Previous report
We anticipate providing preliminary clinical data from our Phase 1 clinical trial of ADI-001 in lupus nephritis in the fourth quarter of 2024 or first quarter of 2025, subject to study site activation and enrollment, and to begin to provide preliminary clinical data in the additional autoimmune indications starting in the fourth quarter of 2024 or first half of 2025, subject to clearance of INDs in those indications as well as successful site initiation and patient enrollment in the relevant clinical protocols.
Previous report
In March 2021, we initiated the first-in-human Phase 1 (GLEAN) trial to assess safety and efficacy of ADI-001 in patients with relapsed or refractory aggressive B cell NHL. The study includes a dose escalation portion followed by dose expansion cohorts to explore the activity of ADI-001 in multiple subtypes of NHL. In April 2022, the FDA granted fast track designation for ADI-001 for NHL. As of the May 4, 2023 cutoff date, of the 24 evaluable subjects in the GLEAN trial, 18 had large B cell lymphoma (LBCL), five had mantle cell lymphoma (MCL), and one patient had follicular lymphoma. Most patients were heavily pre-treated, with a median four lines of prior therapy, and twelve patients (50%) had previously progressed following CAR T cell therapy. Despite the advanced nature of patients at baseline, we observed a high complete response (CR) rate and favorable durability in MCL patients. Across all doses of MCL patients, we observed an 80% (4/5 patients) overall response rate (ORR), an 80% CR rate (4/5 patients) and a 60% CR rate (3/5 patients) at six months. As of May 4, 2023, the safety profile of ADI-001 was generally favorable, with no significant risk of cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), or T cell malignancy observed. In November 2023, we initiated an expansion cohort, EXPAND, in post-CAR T LBCL. In January 2024, we announced our decision to deprioritize enrolling LBCL patients in the GLEAN trial in order to focus on advancing MCL enrollment.
Previous report
We expect to provide a clinical update from the Phase 1 study in NHL patients which will include efficacy data, including six-month CR rate, and safety data from additional MCL patients in the second half of 2024. Subject to clinical data and regulatory feedback, in the first half of 2025, we plan to define the regulatory path for a potentially pivotal Phase 2 study for ADI-001 in MCL and provide a further clinical update in the second half of 2025.
Previous report
We have expanded manufacturing capabilities of ADI-001 by transferring the manufacturing process to an additional contract development and manufacturing organization (CDMO) that is capable of operating at a larger scale of production.

1000 Bridge Parkway Lease and Letter of Credit
Previous report
On January 9, 2023, we entered into a third lease amendment (the Third Amendment) with Westport Office Park, LLC (Westport). The Third Amendment further amends the Redwood City Lease and increases the tenant improvement allowance as of January 1, 2023 by an additional $3.0 million. We expect to utilize the full allowance for the continued buildout of office and laboratory space at 1000 Bridge Parkway. Per the terms of this amendment, this additional allowance will be repaid through equal monthly payments of principal amortization and interest on a monthly basis over the term of the lease at an interest rate of eight percent (8%) per annum. We received the allowance on February 21, 2023.
Previous report
On August 7, 2023, we entered into a fourth lease amendment (the Fourth Amendment) with Westport. The Fourth Amendment amended the period over which the tenant improvement allowance received in the Third Amendment will be amortized and identified our monthly amortization payable.
Previous report
On September 1, 2023, we amended our letter of credit with Westport. The amendment reduced the amount of the letter of credit associated with our 1000 Bridge Parkway facility by $2.1 million resulting in an updated letter of credit amount of $2.1 million.

Option Repricing
Previous report
On August 8, 2023, our board of directors approved a stock option repricing (the Option Repricing) to be effective on August 14, 2023 (the Effective Date) in accordance with the terms of our 2015 Stock Incentive Plan and 2018 Plan (together, the Plans). Pursuant to the Option Repricing and subject to a one year cliff period, the exercise price of each stock option previously granted under the Plans, totaling 6,431,910 options, was amended to reduce the exercise price of such options to $2.14 per share, the closing price of our common stock on the Nasdaq Global Market on the Effective Date. Under the terms of the Option Repricing, a repriced option will revert to its original exercise price if, prior to the one-year anniversary of the Effective Date, (a) the option holder’s employment is terminated by us with cause or by the option holder or (b) the option is exercised. The repriced options otherwise retained their existing terms and conditions as set forth in the Plans and applicable award agreements.
Previous report
In addition, as of the Effective Date, we issued 1,418,042 options to purchase shares of common stock under the 2018 Plan to eligible employees who held inducement awards as of August 8, 2023. These new options were issued to eligible employees because their inducement awards granted under Nasdaq Listing Rule 5635(c)(4) are not eligible for repricing. The prior inducement awards remain outstanding under their original terms.

Underwritten Public Offering
Previous report
In January 2024, we sold an aggregate of 6,350,000 shares of common stock in a series of sales in accordance with our “at-the-market” offering program (ATM Program) with JonesTrading Institutional Services LLC (Sales Agent), at an average price of $3.13 per share, for aggregate net proceeds of approximately $19.3 million, after deducting sales agent commissions, but before deducting any expenses related to such sales. As of the date of this Annual Report on Form 10-K, up to $80.1 million of our common stock remains available for sale from time to time under our ATM Program. In March 2024, we terminated our ATM Program.
Previous report
We received a non-refundable upfront payment of $25.0 million from Regeneron upon execution of the Regeneron Agreement on July 29, 2016 and have received an aggregate of $20.0 million of additional payments for research funding from Regeneron as of December 31, 2023. Our obligations under the Regeneron Agreement were completed during the first quarter of 2022. Regeneron may have to pay us additional amounts in the future consisting of up to an aggregate of $80.0 million of option exercise fees for a certain number of Interprofessional Collaboration Practices (ICPs). On January 28, 2022, we received a payment of $20.0 million from Regeneron for exercise of its option to license exclusive rights to ADI-002 and Regeneron potentially has additional options to other Collaboration ICP targets under the Regeneron Agreement. We declined to exercise our option to co-fund the development of ADI-002 with Regeneron, and accordingly, Regeneron must also pay us high single digit royalties as a percentage of net sales for ADI-002 or any other optioned ICPs to targets for which it has exclusive rights and low single digit royalties as a percentage of net sales on any non-ICP product comprising a target generated by us through the use of Regeneron’s proprietary mice. We must pay Regeneron mid-single to low double digit royalties as a percentage of net sales of Collaboration ICPs to targets for which we have exercised exclusive rights, and low to mid-single digit royalties as a percentage of net sales of targeting moieties generated from our license to use Regeneron’s proprietary mice. Royalties are payable until the longer of the expiration or invalidity of the licensed patent rights or 12 years from first commercial sale.
Previous report
We used a cost-based input method to measure proportional performance and to calculate the corresponding amount of revenue to recognize under the Regeneron Agreement. In applying the cost-based input method of revenue recognition, we used actual costs incurred relative to budgeted costs to fulfill the combined performance obligation. Revenue was recognized based on actual costs incurred as a percentage of total budgeted costs as we completed our performance obligations over the research term. A cost-based input method of revenue recognition requires us to estimate costs to complete our performance obligations, which requires significant judgment to evaluate assumptions related to cost estimates. The cumulative effect of revisions to estimated costs to complete our performance obligations is recorded in the period in which changes are identified and amounts can be reasonably estimated.
Previous report
Revenue
Previous report
Revenue decreased by $25.0 million, or 100%, for the year ended December 31, 2023 compared to the year ended December 31, 2022. The decrease was due to no revenue recognized under the Regeneron Agreement in the current period. Our obligations under the combined performance obligation with Regeneron were completed during the first quarter of 2022, resulting in revenue fully recognized under the agreement as of March 31, 2022.
Previous report
Other expense decreased by $0.3 million, or 38%, during the year ended December 31, 2023 compared to the year ended December 31, 2022, which was primarily due to a decrease in franchise and capital taxes for the period.
Previous report
In August 2022, we received net proceeds of $43.6 million from the sale of shares of our common stock under our ATM Program with the Sales Agent and, in January 2024, we received net proceeds of $19.3 million from the sale of shares of our common stock under our ATM Program. Up to $80.1 million of shares of our common stock remains available for sale under our ATM Program, providing us with an additional source of liquidity, subject to market conditions. In March 2024, we terminated our ATM Program.
Previous report
As of December 31, 2023, we have $12.7 million available under the Loan Agreement. As of the date of this Annual Report on Form 10-K, we were in compliance with such covenants and had no indebtedness outstanding under the Loan Agreement.
Previous report
Net cash provided by financing activities was $41.5 million for the year ended December 31, 2022, which primarily consisted of $43.4 million in proceeds from the issuance of common stock pursuant to our ATM Program and $1.7 million in cash proceeds from the exercise of stock options and purchases under our Employee Stock Purchase Plan. Net cash provided by financing activities was partially offset by $3.2 million of taxes withheld and paid related to net share settlement of employee equity awards and $0.4 million related to deferred issuance costs.
Previous report
Expected Term — The expected term is calculated using the simplified method which is used when there is insufficient historical data about exercise patterns and post-vesting employment termination behavior. The simplified method is based on the vesting period and the contractual term for each grant, or for each vesting-tranche for awards with graded vesting. The mid-point between the vesting date and the maximum contractual expiration date is used as the expected term under this method. For awards with multiple vesting-tranches, the times from grant until the mid-points for each of the tranches may be averaged to provide an overall expected term.
Previous report
Expected Volatility — The Company has limited trading history. As such, the expected volatility was determined by examining the historical volatilities of a peer group of comparable publicly traded companies in biotechnology and pharmaceutical related industries to be representative of our expected future stock price volatility. For purposes of identifying these peer companies, we consider the industry, stage of development, size and financial leverage of potential comparable companies. For each grant, we measure historical volatility over a period equivalent to the expected term.
Previous report
Risk-Free Interest Rate — The risk-free interest rate is based on the implied yield currently available on United States Treasury zero-coupon issues with a remaining term equivalent to the expected term of the stock award.
Previous report
Expected Dividend Rate — We have not paid and do not anticipate paying dividends in the near future. Accordingly, we estimate the dividend yield to be zero.

Our lead product candidate, ADI-001, a first-in-class allogeneic gamma delta T cell therapy expressing a CAR targeting CD20, is being developed for the potential treatment of autoimmune diseases and relapsed or refractory aggressive B cell non-Hodgkin's lymphoma (NHL). Our pipeline also includes our lead preclinical candidate, ADI-270, an armored gamma delta CAR T cell product candidate targeting renal cell carcinoma, with potential for other CD70+ solid tumor and hematological malignancies indications. Our pipeline has several additional internal gamma delta T cell therapy programs in discovery and preclinical development for both hematological malignancies and solid tumors. We expect to continue to develop product candidates in autoimmune diseases and cancer based on our gamma delta T cell platform using either previously validated antigens or those that we identify and target using CAR and other technology. We plan to file one new Investigational New Drug (IND) application every 12-18 months, including an IND for ADI-270 in the first half of 2024.

Previous wording
In December 2023, the U.S. Food and Drug Administration (FDA) cleared our IND application for ADI-001 in lupus nephritis, an autoimmune disease caused by systemic lupus erythematosus (SLE). Lupus nephritis is a serious complication of SLE which affects approximately 40% of the estimated 325,000 patients with SLE in the U.S. We expect to initiate a Phase 1 clinical trial of ADI-001 for the treatment of lupus nephritis in the second quarter of 2024 and expand development of the candidate into one to two additional autoimmune indications in the second and third quarters of 2024, subject to clearance of INDs in those indications. We believe the potential market opportunity for ADI-001 in B cell mediated autoimmune diseases is substantial based on the prevalence in the U.S., EU5, China and Japan of greater than 1.7 million patients with autoimmune diseases where CAR-T cell therapy has demonstrated clinical proof-of-concept, including SLE (which includes lupus nephritis), systemic sclerosis and idiopathic inflammatory myopathies.
Current wording
In December 2023, the U.S. Food and Drug Administration (FDA) cleared our IND application for ADI-001 in lupus nephritis (LN). In August 2024, we expanded our ADI-001 autoimmune clinical development program to include systemic lupus erythematosus (SLE), systemic sclerosis (SSc) and anti-neutrophil cytoplasmic autoantibody associated vasculitis (AAV). In September 2024, we activated sites for our Phase 1 clinical trial of ADI-001 in autoimmune diseases and opened enrollment for patients with LN. In October 2024, we received clearance for our IND amendment to evaluate ADI-001 in idiopathic inflammatory myopathies (IIM) and stiff person syndrome (SPS) as part of our Phase 1 clinical trial in autoimmune diseases. We expect to initiate enrollment for patients with SLE, SSc, IIM and SPS in the second quarter of 2025, and for patients with AAV in the second half of 2025. We believe the favorable safety profile, cellular kinetics and B cell depletion in peripheral blood and secondary lymphoid tissue demonstrated with ADI-001 clinical experience to date is favorable for development in autoimmune diseases. We believe the potential market opportunity for ADI-001 in B cell mediated autoimmune diseases is substantial based on the prevalence in the U.S., EU5, China and Japan of greater than 1.7 million patients with autoimmune diseases where CAR-T cell therapy has demonstrated clinical proof-of-concept, including SLE (which includes LN), SSc, IIM and SPS. In June 2024, the FDA granted Fast Track Designation to ADI-001 for the potential treatment of relapsed/refractory class III or class IV LN. In February 2025, the FDA granted Fast Track Designation to ADI-001 for the potential treatment of adult patients with refractory SLE with extrarenal involvement and for SSc. In November 2024, we dosed our first LN patient, and in February 2025, reported that we have dosed a total of three LN patients, in our Phase 1 clinical trial of ADI-001 in autoimmune diseases. We plan to report preliminary LN clinical data from this trial in the first half of 2025, and data for other autoimmune diseases in the second half of 2025, subject to study site initiation and patient enrollment.
Previous wording
ADI-270 is an investigational allogeneic gamma delta CAR T cell therapy targeting CD70 via the CD27-ligand for the treatment of renal cell carcinoma (RCC) and with potential in other solid tumor indications. ADI-270 is designed to home to solid tumors, with a highly specific targeting moiety for CD70 and an armoring technology of transforming growth factor (TGF) beta dominant-negative receptor to address immunosuppressive factors in the tumor microenvironment. Building on gamma delta 1 tissue tropism to solid tumors and three mechanisms of anti-tumor activity (CAR, innate and adaptive), CAR gamma delta 1 T cells may be well positioned to address solid tumors. We plan to file an IND application for ADI-270 in RCC in the second quarter of 2024 and provide clinical data in the first half of 2025, subject to regulatory clearance and study initiation activities. We are also considering potential expansion into additional CD70+ tumor indications in the first half of 2025, with potential clinical data from such studies in the second half of 2025, subject to regulatory clearance and study initiation activities.

Goodwill represents the excess of the purchase price over the fair value of net tangible and identified intangible assets acquired in our merger with resTORbio, Inc. in September 2020. Goodwill is not amortized but is evaluated at least annually for impairment or when a change in facts and circumstances indicate that the fair value of the goodwill may be below the carrying value. If the fair value of the reporting unit is less than the carrying value, we measure the amount of impairment loss, if any, as the excess of the carrying value over the fair value of the reporting unit. This amount is recognized as a goodwill impairment charge for the period. The Company performed an interim test for goodwill impairment in the third quarter of 2023 and determined that the entire balance of goodwill was impaired.

Previous wording
Research and development expenses increased by $34.8 million, or 49%, during the year ended December 31, 2023 compared to the year ended December 31, 2022. The increase in research and development expenses was primarily due to a $10.7 million increase in expenses related to CDMOs and other externally conducted research and development and a $11.5 million increase in payroll and personnel expenses resulting from an increase in overall headcount. In addition, there was an $8.5 million increase in allocated facility expenses and a $4.1 million increase in laboratory expenses for the period. This increase was partially offset by a $0.2 million decrease in professional fees.
Current wording
Research and development expenses decreased by $6.7 million, or 6%, during the year ended December 31, 2024 compared to the year ended December 31, 2023. The decrease in research and development expenses was primarily due to a $7.7 million decrease in expenses related to CDMOs. This decrease was partially offset by a $0.6 million increase in lab expenses as well as a $0.5 million increase in professional fees.
Previous wording
General and administrative expenses increased by $0.2 million, or 1%, during the year ended December 31, 2023 compared to the year ended December 31, 2022. The increase in general and administrative expenses was primarily due to a $3.3 million increase in payroll and personnel expenses, which includes an increase in salaries and benefits of $1.0 million, contractor fees of $0.9 million, stock-based compensation of $1.2 million and recruiting fees of $0.3 million. These increases were the result of increased headcount for the period. The increase was partially offset by a $2.6 million decrease in allocated facility expenses. There was also a $0.5 million decrease in professional fees for the period.
Current wording
General and administrative expenses increased by $1.8 million, or 7%, during the year ended December 31, 2024 compared to the year ended December 31, 2023.

Current wording
Interest income increased by $0.7 million, or 7%, during the year ended December 31, 2024 compared to the year ended December 31, 2023. The increase was primarily due to higher cash balances, investments in treasury securities, and higher interest rates for the period.

On January 22, 2024, we entered into an Underwriting Agreement (the Underwriting Agreement) with Jefferies LLC and Guggenheim Securities, LLC, as representatives of the underwriters (the Underwriters), related to an underwritten public offering (the Offering) of 32,379,667 shares of our common stock, which included 5,325,000 shares sold and issued upon the exercise in full by the Underwriters of their option to purchase additional shares of common stock, and, in lieu of common stock to certain investors, pre-funded warrants to purchase 8,445,333 shares of common stock. The shares of common stock were sold at a public offering price of $2.40 per share and the pre-funded warrants were sold at a public offering price of $2.3999 per pre-funded warrant, which represents the per share public offering price of each share of common stock minus the $0.0001 per share exercise price for each pre-funded warrant. We received net proceeds from the Offering, after deducting the underwriting discount and commissions and other estimated offering expenses, of approximately $91.8 million. We may receive nominal proceeds, if any, from the exercise of the pre-funded warrants.

As of December 31, 2023, we had cash and cash equivalents of $159.7 million. Subsequent to December 31, 2023, we raised aggregate net proceeds of approximately $19.3 million through our ATM Program and approximately $91.8 million through the Offering.

We have based these estimates on assumptions that may prove to be wrong, and we could deplete our available capital resources sooner than we expect. Because of the risks and uncertainties associated with research, development, and commercialization of product candidates, we are unable to estimate the exact amount of our working capital requirements.

Previous wording
Net cash used in operating activities was $44.8 million for the year ended December 31, 2022. Cash used in operating activities consisted of net loss and non-cash adjustments of $22.3 million as well as an increase in assets and liabilities of $2.7 million. Non-cash items primarily included stock-based compensation expense of $17.1 million, non-cash lease expense of $2.4 million and depreciation and amortization of $2.6 million. The net change in assets and liabilities was primarily due to an increase in accrued and other current and non-current liabilities of $5.8 million, an increase in accounts payable of $1.7 million and an increase in prepaid expenses and other current assets of $1.3 million. The increase was partially offset by a decrease in deferred revenue of $4.8 million related to the Regeneron Agreement and a decrease in operating lease liability of $2.3 million.

Net cash used in operating activities was $92.4 million for the year ended December 31, 2024. Cash used in operating activities consisted of net loss offset by non-cash adjustments of $30.3 million and a net decrease in operating assets and liabilities of $5.5 million. Non-cash items primarily included stock-based compensation expense of $22.2 million, depreciation and amortization of $6.5 million and non-cash lease expense of $3.2 million. The net decrease in assets and liabilities was primarily due to a decrease of $3.7 million in operating lease liability, a decrease of $2.0 million in accrued and other current and non-current liabilities and a decrease of $1.3 million in prepaid expenses and other current assets. The decrease was partially offset by an increase in accounts payable of $1.1 million and an increase in other non-current assets of $0.4 million.
Previous wording
We use a fair value-based method to account for all stock-based compensation arrangements with employees and non-employees, including stock options and restricted stock awards. Our determination of the fair value of stock options on the date of grant utilizes the Black-Scholes option pricing model. The fair value of the option granted is recognized on a straight-line basis over the period during which an optionee is required to provide services in exchange for the option award, known as the requisite service period, which usually is the vesting period. For awards that have a performance condition, the Company recognizes compensation expense based on its assessment of the probability that the performance condition will be achieved, using an accelerated attribution model, over the explicit or implicit service period. We account for forfeitures as they occur. In determining fair value of the stock options granted, we use the Black–Scholes option-pricing model, which requires the input of subjective assumptions. These assumptions include estimating the length of time employees will retain their vested stock options before exercising them (expected term), the estimated volatility of our common stock price over the expected term (expected volatility), risk-free interest rate and expected dividends. Changes in the following assumptions can materially affect the estimate of fair value and ultimately how much stock-based compensation expense is recognized; and the resulting change in fair value, if any, is recognized in our consolidated statements of operations during the period the related services are rendered. These inputs are subjective and generally require significant analysis and judgment to develop. Changes in the following assumptions can materially affect the estimate of the fair value of stock-based compensation:
