Current report

We are an oncology company developing next-generation antibody-drug conjugates (“ADCs”) designed around novel proprietary cancer-killing toxins (“payloads”). We believe these novel payloads may have the potential to transform the efficacy and safety outcomes of ADCs as cancer therapies beyond options that are currently available or in development.

Current report

ADCs are a class of cancer therapies that combine the precision targeting of antibodies with payload toxins that attack cancer cells. To date, innovation in the field of ADC therapies has focused primarily on the development of novel antibodies linked to existing classes of payload toxins. For example, there is a range of approved ADCs with antibodies that target the Her2, Trop2, CD19, CD22, CD30, Nectin-4, Tissue Factor, and FR alpha antibodies. But there is a surprising lack of diversity in the payload toxins to which those antibodies are linked, as all of these marketed products, and more than 90% of ADCs in late-stage clinical development of which we are aware, utilize payloads from just two standard classes: (1) microtubule inhibitors or (2) DNA-damaging agents such as topoisomerase I inhibitors.

Current report

Our differentiated ADC discovery and development platform (our “ADC Platform”) enables us to generate a range of ADC product candidates that pair our novel payloads with biologically validated antibody targets prevalent in cancer tumors. We believe that our focus on the development of ADCs that utilize our novel payloads may allow us to develop ADCs with benefits that include:

Current report

generation of greater numbers of neoepitopes than currently available ADCs, leading to activation of both B-cells and T-cells in the tumor microenvironment to generate an immune response that has the potential to continue to kill cancer cells in the tumor microenvironment and throughout the body;

Current report

ability to be used in combination with checkpoint inhibitors to potentially deliver synergistic efficacy results (more than additive);

Current report

sustained duration of response of tumor regression or elimination;

Current report

improved safety and tolerability relative to ADCs that are currently available.

Current report

Our lead product candidate is AKTX-101, a preclinical stage Trop2-targeting ADC that combines PH1 with the Trop2 antibody, which is expressed in the highest number of solid tumor cancer types, including lung, breast, colon and prostate. We aim to establish AKTX-101 as a best-in-class Trop2-targeting ADC for the treatment of a variety of solid tumors.

Current report

We acquired the ADC Platform in connection with the acquisition of Peak Bio (the “Merger”). Prior to that time, we were primarily focused on advancing our former lead product candidates nomacopan and PAS-nomacopan (longer-acting nomacopan that is PASylated). Since the closing of the Merger, we have focused substantially all of our efforts on the development of ADCs and our ADC Platform. We have suspended further internal development of our legacy programs, nomacopan and PAS-nomacopan, and intend to seek strategic partners to advance their development externally. For our PHP-303 program, a program that Peak Bio had advanced prior to the closing of the Merger, we intend to seek strategic partners for it as well to further its development externally.

Current report

We do not have any products available for commercial sale, and we have not generated any product revenue from our portfolio of product candidates or other sources. Our ability to generate revenue sufficient to achieve profitability, if ever, will depend on the successful development and eventual commercialization of our potential therapies, which we expect, if it ever occurs, will take a number of years. The research and development efforts require significant amounts of additional capital and adequate personnel infrastructure. There can be no assurance that our research and development activities will be successfully completed, or that our potential therapies will be commercially viable.

Current report

On March 14, 2025, we entered into an Executive Offer of Employment Agreement (as amended by a subsequent Chief Executive Officer Letter Agreement, dated March 18, 2025) with Mr. Abizer Gaslightwala pursuant to which Mr. Gaslightwala will serve as our President and Chief Executive Officer, effective on April 21, 2025. Mr. Gaslightwala will earn a base salary, which includes an annual cash bonus target, and receive share-based payment compensation based on time service and the achievement of specific performance criteria.

Current report

On March 2, 2025, we entered into the March 2025 Purchase Agreement, pursuant to which we agreed to sell and issue in a private placement (the “March 2025 Offering”) an aggregate of 6,637,626 ADSs, or prefunded warrants in lieu thereof (“Pre-Funded Warrants”), and, in each case, Series A Warrants and Series B Warrants, together with the Pre-Funded Warrants and Series A Warrants, the “Warrants,” and together with the ADSs or Pre-Funded Warrants, the “Units”)). The Units consist of (i) for investors committing less than $1.0 million in the March 2025 Offering (“Tier 1 Investors”) one ADS or Pre-Funded Warrant plus a Series A Warrant to purchase one ADS and a Series B Warrant to purchase one ADS, (ii) for investors committing at least $1.0 million but less than $3.0 million in the March 2025 Offering (“Tier 2 Investors”) one ADS or Pre-Funded Warrant plus a Series A Warrant to purchase 1.25 ADSs and a Series B Warrant to purchase one ADS, and (iii) for investors committing $3.0 million or more in the March 2025 Offering (“Tier 3 Investors”), one ADS or Pre-Funded Warrant plus a Series A Warrant to purchase 1.5 ADSs and a Series B Warrant to purchase one ADS. The purchase price per Unit for investors purchasing ADSs is equal to $0.87 plus (a) $0.25 for Tier 1 Investors, (b) $0.28125 for Tier 2 Investors, or (c) $0.3125 for Tier 3 Investors (the “ADS Unit Purchase Price”). The purchase price per Pre-Funded Warrant and accompanying Series A Warrant and Series B Warrant is equal to $0.67 (which represents the ADS purchase price minus the $0.20 exercise price for such Pre-Funded Warrant) plus (a) $0.25 for Tier 1 Investors, (b) $0.28125 for Tier 2 Investors, or (c) $0.3125 for Tier 3 Investors (the “Pre-Funded Unit Purchase Price”).

Current report

As part of the March 2025 Offering, Dr. Hoyoung Huh, our Chairman of the Board, agreed to purchase $1 million of Units, with the purchase price thereof to be satisfied through his agreement to cancel and extinguish $1.0 million of notes previously issued to him by the Company (the “Note Termination”) for an equal amount of ordinary shares and warrants.

Current report

The net proceeds from the March 2025 Offering, after deducting placement agent fees and other offering expenses payable by us, were approximately $6.0 million, of which $4.0 million was received in April 2025.

Current report

In addition to a cash commission, the placement agent was also paid three percent (3%) of the total number of ADSs issued in the March 2025 Offering, including any of the ADSs issuable upon exercise of the Pre-Funded Warrants (excluding the ADSs issued to Dr. Huh in respect to the Note Termination).

Current report

For additional information on the Merger, refer to our Form 10-K for the fiscal year ended December 31, 2024.

Current report

During the three months ended March 31, 2025, our loss from operations totaled $3.5 million, a 41% decrease, compared to a loss from operations of $6.0 million for the three months ended March 31, 2024. General and administrative expenses comprise the majority of our total operating expenses, as shown in the table below:

Current report

These expenses include external expenses that we incurred in connection with the research and discovery of our ADC platform and program(s), and primarily consist of payments to CROs and other vendors. In December 2024, we announced our strategic prioritization of our ADC technology and programs and expect to incur material additional costs related to this program as we will invest in additional ADC related preclinical research and discovery activities.

Current report

These expenses include compensation and related costs associated with employees, independent consultants and staffing firms. The less than $0.1 million, or 3% decrease during the three months ended March 31, 2025, as compared to the three months ended March 31, 2024, is primarily due to lower cash-based salaries, offset by increases in non-cash stock based compensation expense.

Current report

During the three months ended March 31, 2025, total general and administrative costs decreased by approximately $1.0 million, or 27%, as compared to the three months ended March 31, 2024, primarily due to decreases in legal and professional fees of approximately $1.0 million (primarily related to the Merger) and a decrease of approximately $0.2 million in directors and officers insurance.

Current report

During the three months ended March 31, 2025, we recorded a gain on debt extinguishment related to our November 2022 Note of less than $0.1 million. Refer to Note 6 of our unaudited condensed consolidated financial statements included in this Form 10-Q. No such gain was recognized during the three months ended March 31, 2024.

Current report

In March 2025, we entered into the March 2025 Purchase Agreement with certain investors, including all of our directors, pursuant to which we agreed to sell and issue in a private placement an aggregate of a combination of Units. For more information, see “Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Recent Developments—March 2025 Private Placement.”

Current report

In November 2024, we entered into a definitive purchase agreement with certain investors, Dr. Ray Prudo and Dr. Samir Patel, pursuant to which we sold and issued in a private placement an aggregate of 1,713,402 ADSs, and Series D Warrants (the “Series D Warrants”) to purchase up to 1,713,402 ADSs, at a per unit price of $2.26 for aggregate gross proceeds of $3.2 million (the “November 2024 Private Placement”). The Series D Warrants have 3-year terms ranging from December 2, 2027 to June 2, 2028 and have cashless exercise provisions in limited circumstances.

Current report

At close of the November 2024 Private Placement, we incurred a total of $204,000 in placement agent fees with Paulson Investment Company, LLC (“Paulson”). Net proceeds from the November 2024 Private Placement were approximately $2.8 million after deducting placement agent fees and other expenses. In April 2025, we issued 408,000,000 ordinary shares to Paulson in lieu of $204,000 in cash payment.

Current report

In May 2024, we entered into a definitive purchase agreement with certain investors, Dr. Ray Prudo and Dr. Samir Patel, pursuant to which we sold and issued in a private placement an aggregate of 4,029,754 ADSs, and May 2024 Series C Warrants (the “Series C Warrants”) to purchase up to 4,029,754 ADS, at a per unit price of $1.885 per ADS and Series C Warrant for aggregate gross proceeds of approximately $7.6 million (the “May 2024 Private Placement”). The Series C Warrants have 3-year terms ranging from May 31, 2027 to June 21, 2027 and have cashless exercise provisions in limited circumstances. The Series C Warrants (other than those issued to Dr. Prudo and Dr. Patel) have an exercise price of $1.76 per ADS. The Series C Warrants issued to Dr. Prudo and Dr. Patel have an exercise price of $1.79 per ADS. Net proceeds from the May 2024 Private Placement were approximately $7.0 million after deducting placement agent fees and other expenses.

Current report

In May 2024, we entered into unsecured convertible promissory notes (the “May 2024 Notes”) with Dr. Prudo, our Chairman at the time, and our then Interim President and Chief Executive Officer and director, Dr. Patel, for an aggregate of $1.0 million in gross proceeds. The May 2024 Notes bear interest at 15% per annum, which may be increased to 17% upon the occurrence of certain events of default as described therein, and the principal and all accrued but unpaid interest is due on the date that is the earlier of (a) ten (10) business days following our receipt of a U.K. research and development tax credit from HM Revenue and Customs, and (b) November 10, 2024. Provided, however, at any time or times from the date of the note and until the tenth business day prior to closing of the acquisition, the note holders are entitled to convert any portion of the outstanding and unpaid amount, including principal and accrued interest, into our ADSs at a fixed conversion price equal to $1.59, representing the Nasdaq official closing price of our ADSs on the issuance date, subject to certain restrictions.

Current report

In October 2024, Drs. Prudo and Patel each elected to convert $125,000 of principal and accrued interest into our ADSs at a conversion price of $1.59 per ADS. These ordinary shares remain unissued as of December 31, 2024 and are expected to be issued during the second quarter of 2025. The remaining unconverted aggregate principal balance of the May 2024 Notes, or $750,000, was repaid in cash with proceeds from our U.K. research and development tax credit from HM Revenue and Customs.

Current report

For the three months ended March 31, 2025, an aggregate of $1.2 million in net proceeds received from the March 2025 Private Placement, an aggregate of $1.1 million received from advance deposits related to the second closing of the March 2025 Private Placement that occurred subsequent to March 31, 2025, partially offset by $0.5 million of payments related to our promissory notes and $0.1 million of payments for our insurance premium financing; and

Current report

In January 2025, we entered into a short-term financing arrangement with a third-party vendor to finance insurance premiums. The aggregate amount financed under this agreement was $0.5 million which is scheduled to be paid in monthly installments through November 2025.

Current report

In November 2024 as part of the Merger, we assumed convertible notes and notes payable with third parties, and notes payable with a related party, through the acquisition of Peak Bio Inc., as more fully described in Note 6 and Note 12, respectively, to our unaudited condensed consolidated financial statements appearing in this Form 10-Q. As of March 31, 2025, these obligations are expected to result in principal payments of approximately $1.6 million.

Current report

We enter into a variety of agreements and financial commitments in the normal course of business. The terms generally provide us the option to cancel, reschedule and adjust our requirements based on our business needs, prior to the delivery of goods or performance of services. However, it is not possible to predict the amount of future payments under these agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement.

Previous report

Our lead product candidate, nomacopan, is a recombinant small protein (16,769 Da) derived from a protein originally discovered in the saliva of the Ornithodoros moubata tick, which modulates the host immune system to allow the parasite to feed without alerting the host to its presence or provoking an immune response. Nomacopan is a second-generation complement inhibitor which has been shown to act on complement C5, preventing release of C5a and formation of C5b-9 (also known as the membrane attack complex (“MAC”)). Nomacopan also specifically sequesters and inhibits LTB4. Complement C5 and LTB4 activation and their proinflammatory actions are typically co-localised during an immune reaction. With its unique bispecific mode of action and biophysical properties, we believe nomacopan may be able to prevent inflammatory and prothrombotic activities of these two important pathways and also and has the potential to be formulated for administration by a variety of routes including subcutaneous, intravenous, topical to eye, inhaled and intravitreous.

Previous report

We are investigating PAS-nomacopan, a long-acting form of nomacopan that is a bispecific inhibitor of C5 and LTB4, for the intravitreal treatment of geographic atrophy (“GA”) secondary to dry age-related macular degeneration (“AMD”) in preclinical studies. Following a positive and constructive Pre-Investigational New Drug application meeting with FDA in August 2024, we are completing final non-clinical studies and Good Manufacturing Practices (“GMP”) manufacturing and expect to file an Investigational New Drug Application (“IND”) with the FDA in 2025 for PAS-nomacopan in GA. We believe PAS-nomacopan has the potential for longer dose intervals between intravitreous injections than currently approved complement only inhibitors, as well as potential reduction of the choroidal neovascularization (“CNV”) risk that is associated with approved inhibitors. CNV is a sight-threatening over development of blood vessels within the retina, which is typically treated with anti-vascular endothelial growth factor (“VEGF”) intravitreal injections. As a bispecific inhibitor of complement C5 and LTB4 we believe PAS-nomacopan may be more efficacious than marketed treatments for GA that only inhibit complement.

Previous report

Until May 2024, we were conducting a clinical trial of subcutaneous nomacopan for the treatment of hematopoietic stem cell transplant-related thrombotic microangiopathy (“HSCT-TMA”) in pediatrics. Following completion of a portfolio prioritization review, we announced that our HSCT-TMA program will be suspended, as more fully described below.

Previous report

For additional information on the Merger and the Closing, refer to Note 3 and Note 10 to the notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q.

Previous report

These expenses previously included external expenses that we incurred in connection with the development of nomacopan for the treatment of bullous pemphigoid (“BP”) and primarily consist of payments to CROs and other vendors. In 2022, we discontinued our BP clinical program and in connection with the final reconciliation of clinical trial close-out costs, we recorded a $1.1 million credit in 2023 and do not expect to incur material additional costs related to this program.

Previous report

These expenses include compensation and related costs associated with employees, independent consultants and staffing firms. The $0.5 million, or 60%, decrease in expenses incurred during the three months ended September 30, 2024 and $1.2 million, or 48%, decrease in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily due to the impact of the RIF which was announced in May 2024, along with lower costs incurred with consultants. Separation benefits paid to impacted employees are classified separately under “Restructuring and other costs” as discussed below.

Previous report

We record receipts of U.K. tax credits in the year received as a reduction in research and development expenses. Changes in tax credits received are the result of eligible research and development expenses incurred in the previous tax year, which can fluctuate depending on timing of and location in which expenses are incurred.

Previous report

During the three months ended September 30, 2024, total general and administrative costs decreased by approximately $1.1 million, or 39%, as compared to the three months ended September 30, 2023. During the nine months ended September 30, 2024, total general and administrative costs decreased by approximately $2.2 million, or approximately 25%, as compared to the nine months ended September 30, 2023. The decreases during both periods were primarily due to decreases in personnel costs resulting from the impact of the RIF which was announced in May 2024, along with lower costs incurred with consultants. Separation benefits paid to impacted employees are classified separately under “Restructuring and other costs” as discussed below.

Previous report

Merger-related costs consist of direct expenses incurred in connection with the proposed Merger and are comprised primarily of legal and professional fees.

Previous report

Merger-related costs for the three and nine months ended September 30, 2024 were $1.0 million and $2.3 million, respectively. No such costs were incurred during the corresponding 2023 periods.

Previous report

Restructuring costs consist primarily of severance and related benefit costs related to workforce reductions incurred in connection with the RIF, which the Company began to implement in May 2024.

Previous report

Restructuring and other costs for the three and nine months ended September 30, 2024 were $0.1 million and $1.7 million, respectively, and includes $0.3 million of non-cash share-based compensation expense for the nine months ended September 30, 2024. No such costs were incurred during the corresponding 2023 periods.

Previous report

Interest income consists primarily of interest income received on deposits.

Previous report

During the nine months ended September 30, 2024 and 2023, we recorded a change in the fair value of warrant liability, representing a non-cash warrant revaluation gain, of approximately $0.5 million and $5.9 million, respectively. Changes in the fair value of the warrant liability and resulting warrant revaluation gains for each of the nine months ended September 30, 2024 and 2023 was driven by a decrease in our stock price and decreases in expected term and expected volatility assumptions during the reporting period.

Previous report

As discussed in Note 10 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in November 2024, we entered into a purchase agreement with certain investors, pursuant to which we agreed to sell and issue in a private placement an aggregate of 1,713,402 ADSs, and warrants to purchase up to 1,713,402 ADS, at a per unit (each unit consists of one ADS and one warrant) purchase price of (i) $1.70 per ADS and warrant for all investors other than Drs. Patel and Prudo, and (ii) $2.385, which is equal to the consolidated closing bid price of the ADSs on The Nasdaq Stock Market on November 12, 2024 plus $0.125 for Drs. Patel and Prudo, for aggregate gross proceeds of $3.2 million.

Previous report

As discussed in Note 6 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in May 2024, we entered into a purchase agreement with certain investors, pursuant to which we sold and issued in a private placement an aggregate of 4,029,754 ADSs, and warrants to purchase up to 4,029,754 ADS, at a per unit (each unit consists of one ADS and one warrant) purchase price of $1.885, for aggregate gross proceeds of approximately $7.6 million. Net proceeds from the May 2024 Private Placement were approximately $7.0 million after deducting placement agent fees and other expenses.

Previous report

As discussed in Note 2 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in May 2024, we entered into convertible promissory notes with existing investors and directors, Dr. Prudo and Dr. Patel, for an aggregate of $1.0 million (the “May 2024 Notes”).

Previous report

continued compliance with both Nasdaq continued listing requirements and Exchange Act requirements.

Previous report

For the nine months ended September 30, 2024, an aggregate of $8.7 million in net proceeds received from debt and equity financings, including (i) $1.7 million in net proceeds from the March 2024 Private Placement, (ii) $1.0 million in net proceeds from the issuance of the May 2024 Notes, and (iii) $7.0 million in net proceeds from the May 2024 Private Placement, partially offset by $0.9 million in payments related to our short-term insurance premium financing arrangement; and

Previous wording

We are a biotechnology company focused on developing advanced therapies for autoimmune and inflammatory diseases involving the complement component 5 (“C5”) and leukotriene B4 (“LTB4”) pathways. Each of these pathways has scientifically well-supported causative roles in the diseases we are targeting. We believe that blocking early mediators of inflammation will prevent initiation and continual amplification of the processes that cause certain diseases. Our activities since inception have consisted of performing non-clinical and clinical research and development activities and raising capital.

Current wording

Our activities since inception have consisted of performing research and development activities and raising capital.

Previous wording

In May 2024, we announced the completion of a joint portfolio prioritization review pursuant to which the anticipated combined entity, following completion of the proposed Merger (as defined below), will focus on Peak Bio’s antibody drug conjugate (“ADC”) platform technology and our PAS-nomacopan GA program. As a result, our HSCT-TMA program was suspended, with enrollment in our pediatric clinical study discontinued due to cost and timeline. Following the closing of the Merger on November 14, 2024, we have expanded our pipeline of assets spanning early and late development stages with the addition of Peak Bio’s ADC toolkit with novel payload and linker technologies as well as the Peak Bio PHP-303 small molecule selective and reversible neutrophil elastase inhibitor. The ADC program includes a novel pre-clinical ADC candidate targeting TROP-2. By combining chemotherapy with immunotherapy strategies, we aim to develop cutting-edge solutions for cancer patients. Further, related to PHP-303, we expect to emphasize partnering/collaboration and licensing opportunities with broad potential impact on patients. We also plan to work closely with the FDA to define the best path for this platform and will pursue opportunities for external partnering/collaboration and licensing for nomacopan, including as a potential treatment for pediatric HSCT-TMA.

Current wording

In May 2024, we announced the completion of a joint portfolio prioritization review pursuant to which the anticipated combined entity, following completion of the proposed Merger (as defined below), will focus on Peak Bio’s ADC platform technology. As a result, our clinical stage nomacopan program in HSCT-TMA was suspended, with enrollment in our pediatric clinical study discontinued due to cost and timeline. Our preclinical PAS-nomacopan program in Geographic Atrophy (“GA”) has also been suspended from further internal development and we are looking for an external licensing partner to continue its further development. Following the closing of the Merger on November 14, 2024, we expanded our pipeline of assets from Peak Bio spanning preclinical to clinical stage development with the addition of Peak Bio’s proprietary ADC technology platform with novel payload and linker technologies, as well as the Peak Bio PHP-303 small molecule selective and reversible neutrophil elastase inhibitor. The ADC program includes a novel pre-clinical ADC candidate AKTX-101 targeting TROP-2. By potentially combining our ADC program with other immunotherapy strategies, we aim to develop cutting-edge solutions for cancer patients. Further, related to our PHP-303 program, we expect to emphasize partnering/collaboration and licensing opportunities with broad potential impact on patients.

Previous wording

In May 2024, we began to implement a reduction-in-force (the “RIF”) of approximately 67% of our total workforce, as a result of the recently announced program prioritization under which our HSCT-TMA program was suspended. The RIF is part of an operational restructuring plan and includes the elimination of certain senior management positions and was substantially completed by the end of the second quarter. The purpose of the restructuring plan, including the reduction-in-force, is to reduce HSCT-TMA related operating costs, while supporting the execution of our long-term strategic plan. For additional information, refer to the below discussion under the heading “Restructuring and Other Costs” and Note 2 to the notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q.

During the nine months ended September 30, 2024, our loss from operations totaled $16.4 million, a 40% increase, compared to a loss from operations of $11.7 million for the nine months ended September 30, 2023. Our total operating expenses are set forth by category in the table below:

Previous wording

During the three months ended September 30, 2024, total research and development expenses increased by approximately $0.5 million, or 146%, as compared to the three months ended September 30, 2023. During the nine months ended September 30, 2024, total research and development expenses increased by approximately $2.8 million, or 95%, as compared to the nine months ended September 30, 2023. The following sets forth research and development expenses for the three and nine months ended September 30, 2024 and 2023 by category:

Current wording

During the three months ended March 31, 2025, total research and development expenses decreased by approximately $1.5 million, or 64%, as compared to the three months ended March 31, 2024. The following sets forth research and development expenses for the three months ended March 31, 2025 and 2024 by category:

Previous wording

These expenses include external expenses that we have incurred in connection with the development of nomacopan for the treatment of pediatric HSCT-TMA and primarily consist of payments to CROs and other vendors. The $0.1 million, or 31%, increase in expenses incurred during the three months ended September 30, 2024 and $0.5 million, or 43%, increase in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding 2023 period, is primarily due to changes in clinical trial status and related impact on direct service fees incurred with CROs and timing of investigator payments. While the increase for three months ended September 30, 2024 was primarily due to clinical trial close out costs, the increase for the nine months ended September 30, 2024 was also due to increases in patient enrollment and related clinical trial costs incurred during the first quarter of 2024, prior to suspension of the program. In May 2024, following the completion of a pipeline prioritization review, we determined to suspend our HSCT-TMA program. Accordingly, we expect future HSCT-TMA costs to decrease following completion of the wind-down and closeout of the clinical trial.

Current wording

These expenses include external expenses that we have incurred in connection with the development of nomacopan for the treatment of pediatric HSCT-TMA and primarily consist of payments to CROs and other vendors. The $0.6 million, or 90%, decrease in expenses incurred during the three months ended March 31, 2025, as compared to the three months ended March 31, 2024, is primarily due to our decision to suspend our HSCT-TMA clinical stage program with nomapocan in May 2024.

Previous wording

These expenses include external expenses incurred related to the development and manufacturing of nomacopan for use in clinical trials and preclinical development of PAS-nomacopan. Such expenses primarily consist of payments to CMOs and other vendors for manufacturing of drug substance (including raw materials), drug product, supplies, and validation, quality assurance and manufacturing development activities. The $0.3 million, or 42%, decrease in expenses incurred during the three months ended September 30, 2024 and $1.8 million, or 108%, increase in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily due to the timing of manufacturing and development activities, including decreases in spending on the development of and preparation for manufacturing of PAS-nomacopan during the three months ended September 30, 2024 as a result of the completion of PAS-nomacopan good manufacturing practice (“GMP”) drug substance manufacturing during the second quarter of 2024 which was the primary reason for the increase in costs during the nine months ended September 30, 2024, as compared to 2023.

Current wording

These expenses historically included external expenses incurred related to the development and manufacturing of nomacopan for use in clinical trials and development of PAS-nomacopan. In general, such expenses primarily consist of payments to contract manufacturing organizations and other vendors for manufacturing of drug substance (including raw materials), drug product, supplies, and validation, quality assurance and manufacturing development activities. The $0.7 million, or 96%, decrease in expenses incurred during the three months ended March 31, 2025, as compared to the three months ended March 31, 2024, is primarily due to our decision to suspend our HSCT-TMA program in May 2024.

Previous wording

These expenses include external expenses, such as payments to contract vendors, which may be related to preclinical development activities and other unallocated expenses. The $0.1 million, or 43%, decrease in expenses incurred during the three months ended September 30, 2024 and $0.6 million, or 44%, decrease in expenses incurred during the nine months ended September 30, 2024, each as compared to the corresponding periods in 2023, is primarily related to lower costs incurred related to preclinical studies and other development work investigating PAS-nomacopan for the treatment of GA.

Current wording

These expenses include external expenses, such as payments to contract vendors, that may be related to preclinical development activities, discontinued programs and unallocated expenses. The $0.2 million, or 68%, decrease in expenses incurred during the three months ended March 31, 2025, as compared to the three months ended March 31, 2024, is primarily related to lower costs incurred related to preclinical studies and other development work investigating PAS-nomacopan for the treatment of GA.

Change in fair value of warrant liability represents non-cash warrant revaluation gains or losses related to the remeasurement of our liability-classified September 2022 Warrants, as more fully described in Note 2 and Note 4 of the notes to the condensed consolidated financial statements appearing elsewhere in this Form 10-Q. Due to the nature of and inputs in the model used to assess the fair value of our outstanding September 2022 Warrants, it is not abnormal to experience significant fluctuations during each remeasurement period. These fluctuations may be due to a variety of factors, including changes in our stock price and changes in estimated stock price volatility over the remaining life of the warrants.

Current wording

Change in fair value of warrant liabilities represents non-cash warrant revaluation gains or losses related to the remeasurement of our liability-classified instruments, namely our September 2022 Warrants and the warrants we assumed on November 14, 2024 in connection with our acquisition of Peak Bio (the “Peak Bio Warrants”), which are more fully described in Note 4 of our condensed consolidated financial statements included in this Form 10-Q. Due to the nature of and inputs in the model used to assess the fair value of our outstanding September 2022 Warrants and Peak Bio Warrants, it is not unusual to experience significant fluctuations during each remeasurement period. These fluctuations may be due to a variety of factors, including changes in our stock price and changes in estimated stock price volatility over the remaining life of the warrants.

Previous wording

During the three months ended September 30, 2024, we recorded a change in the fair value of warrant liability, representing a non-cash warrant revaluation gain of less than $0.1 million, as compared to a non-cash warrant revaluation loss of approximately $0.3 million for the three months ended September 30, 2023. Changes in the fair value of the warrant liability and resulting warrant revaluation gain for the three months ended September 30, 2024 was driven primarily by decreases in expected term and expected volatility assumptions during the reporting period. Changes in the fair value of the warrant liability and resulting warrant revaluation loss for the three months ended September 30, 2023 was driven primarily by an increase in our stock price during the reporting period.

Current wording

During the three months ended March 31, 2025 and 2024, we recorded a change in the fair value of warrant liabilities, representing a non-cash revaluation loss of less than $0.1 million and a non-cash revaluation gain of $0.6 million, respectively. Change in the fair value of warrant liabilities and resulting warrant revaluation loss for the three months ended March 31, 2025 was driven by the increase in our stock price and the increase in the expected volatility assumption, offset by decreases in the risk-free interest rate and the expected term assumption during the reporting period. Change in the fair value of warrant liabilities and resulting warrant revaluation gain for the three months ended March 31, 2024 was driven primarily by the decrease in our stock price and the decrease in the expected term assumption during the reporting period.

Previous wording

During the three months ended September 30, 2024, we recorded a net foreign currency exchange gain of $0.1 million, as compared to a net foreign currency exchange loss for the three months ended September 30, 2023. During each of the nine months ended September 30, 2024 and 2023, we recorded a net foreign currency exchange loss of less than $0.1 million. Exchange gains and losses can fluctuate significantly from period to period due to changes in exchange rates as well as the volume and timing of expenditures and related payments denominated in foreign currencies.

Current wording

During the three months ended March 31, 2025 and 2024, we recorded a net foreign currency exchange losses of approximately $0.1 million and $0.2 million, respectively.

We currently do not have any firm commitments for future external funding. We will need to raise additional funds, and we may decide to raise additional funds even before we need such funds if the conditions for raising capital are favorable. Until we can generate significant recurring revenues, we expect to satisfy our future cash needs through debt or equity financings, credit facilities or by out-licensing applications of our product candidates. The sale of equity or convertible debt securities may result in dilution to our existing shareholders. The incurrence of indebtedness would result in increased fixed obligations and could also subject us to covenants that restrict our operations. We cannot be certain that additional funding, whether through grants, financings, credit facilities or out-licensing arrangements, will be available to us on acceptable terms, if at all. If sufficient funds are not available, we may be required to delay, reduce the scope of or eliminate research or development plans for, or commercialization efforts with respect to, one or more applications of our product candidates, or obtain funds through arrangements with collaborators or others that may require us to relinquish rights to certain potential products that we might otherwise seek to develop or commercialize independently.

As discussed in Note 6 to our notes to unaudited condensed consolidated financial statements included elsewhere in this Form 10-Q, in March 2024, we entered into a definitive purchase agreement with certain existing investors, pursuant to which we sold and issued in a private placement an aggregate of 1,320,614 ADSs at $1.48 per ADS, for aggregate gross proceeds of approximately $2.0 million. Net proceeds from the March 2024 Private Placement were approximately $1.7 million after deducting placement agent fees and other expenses.

Net proceeds from the March 2024 Private Placement were approximately $1.7 million after deducting placement agent fees and other expenses.

Previous wording

As of the date of this report, we expect our existing cash, plus cash expected to be received from the November 2024 Private Placement to be sufficient to fund our operations into the first quarter of 2025. We do not currently have any products approved for sale and do not generate any revenue from product sales. We are currently seeking and expect to continue to seek additional funding through financings of equity and/or debt securities. We may also engage in strategic research and development collaborations, clinical funding arrangements, the sale or license of technology assets, and/or other strategic alternatives.

Current wording

As of the date of this report, our existing cash, which includes $4.0 million in cash proceeds received from the March 2025 Private Placement subsequent to March 31, 2025, is sufficient to fund our operations into September 2025. While we have additional funding activities in progress to fund our operations, we will need to raise additional capital to continue to fund our operations and service our obligations in the future. If we are unable to raise additional capital when needed, we will not be able to continue as a going concern. We do not currently have any products approved for sale and do not generate any revenue from product sales. We are currently seeking and expect to continue to seek additional funding through financings of equity and/or debt securities. We may also engage in strategic research and development collaborations, pre-clinical and clinical funding arrangements, the sale or license of technology assets, and/or other strategic alternatives.

Financing may not be available to us when we need it, or on favorable or acceptable terms, or at all. We could be required to seek funds through means that may require us to relinquish rights to some of our technologies, drug candidates or drugs that we would otherwise pursue on our own. In addition, if we raise additional funds by issuing equity securities, our then existing shareholders may experience dilution. The terms of any financing may adversely affect the holdings or the rights of existing shareholders. An equity financing that involves existing shareholders may cause a concentration of ownership. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, and are likely to include rights that are senior to the holders of our ordinary shares. Any additional debt or equity financing may contain terms which are not favorable to us or to our shareholders, such as liquidation and other preferences, or liens or other restrictions on our assets.

Based on our recurring losses from operations incurred since inception, our expectation of continuing operating losses for the foreseeable future, negative operating cash flows for the foreseeable future, and the need to raise additional capital to finance its future operations, we have concluded that there is substantial doubt regarding our ability to continue as a going concern within one year after the date that our unaudited condensed consolidated financial statements, included elsewhere in this Form 10-Q (such unaudited condensed consolidated financial statements, the “consolidated financial statements”) are issued. The accompanying unaudited condensed consolidated financial statements have been prepared assuming that we will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As such, the accompanying condensed consolidated financial statements do not reflect any adjustments relating to the recoverability and classification of recorded assets and liabilities that might be necessary if we are unable to continue as a going concern.

Operating Activities. The net cash used in operating activities for the periods presented consists primarily of our net loss adjusted for non-cash charges and changes in components of working capital. The decrease in cash used in operating activities during the nine months ended September 30, 2024, as compared to the 2023 period, was primarily due to the net impact of deferrals of payables in order to preserve cash until additional capital is raised for working capital purposes, partially offset by an increase in operating expenses.
