Current report

Screening in the Company's FNAIT natural history study is ongoing, with more than 12,000 pregnant women screened as of August 1, 2024. In connection with the initiation of the Phase 2 trial, we will begin to transition European sites from the natural history study to the Phase 2 trial, where sites will continue to collect natural history data in women who do not receive RLYB212. As a result, we expect to see a temporary reduction in screening rates at these sites during such transition. The North American natural history study sites will continue screening activities as currently planned. The totality of natural history data from both studies is designed to provide a contemporary dataset for HPA-1a alloimmunization frequency in a racially and ethnically diverse population that can serve as a control arm for the planned Phase 3 trial.

Current report

Based on the data generated in the MAD portion of the study, we initiated additional manufacturing activities and biomarker analyses. The manufacturing work on RLYB116 is on track to be completed in the third quarter of 2024. Drug substance characterization data indicates that Rallybio's efforts to enhance the manufacturing process have been successful. In addition, we have conducted additional complement biomarker analyses that when taken together with the MAD data lead us to believe that there is an opportunity to pursue indications beyond gMG including PNH and APS at doses tested in the Phase 1 MAD study. We plan to provide an update on future plans for RLYB116 later this year.

Current report

We do not have any product candidates approved for sale and have not generated any revenue from product sales. Our collaboration and license revenue to date is related to data collection and data submission performance obligations pursuant to the two-year Collaboration Agreement with J&J to facilitate the advancement of research into products to address unmet needs relating to FNAIT. Pursuant to the Collaboration Agreement, we received an upfront payment of $0.5 million from J&J for the information dissemination and data provision services under the agreement. In addition, we are eligible for payments upon the achievement of certain enrollment-related events, totaling up to $0.7 million. We are also eligible to receive additional payments upon certain triggers related to the companies' FNAIT studies.

Current report

We evaluated the agreement and determined it was within the scope of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers(“ASC 606”). We determined there were performance obligations as follows:

Current report

(1) Data collection & submission revenue – derived from Rallybio’s ongoing management of the studies including the maintenance of a minimum site footprint, the license to utilize, and timely, semi-annual submission of the anonymized data, in the required formats.

(2) Dissemination of J&J materials & participant revenue – derived from Rallybio’s dissemination of content, information or materials related to the J&J-Sponsored Studies that are developed by J&J and are provided by Rallybio for the purpose of disseminating such content, information, or materials to staff at Rallybio study sites to provide to potential eligible participants regarding J&J’s independent study.

Current report

In April 2024, we also entered into a Securities Purchase Agreement with JJDC. Under the terms of the Securities Purchase Agreement, JJDC made an equity investment purchasing 3,636,363 shares of common stock with a par value of $0.0001 per share for a share purchase price of $1.82 per share which includes a 10% premium for an aggregate purchase price of $6.6 million. The Securities Purchase Agreement contains provisions related to the registration of the shares and the restriction on the sale or transfer of the shares for a period of time. We determined the Collaboration Agreement and Securities Purchase Agreement represented combined agreements. In accordance with ASC 606 and ASC Topic 820, Fair Value Measurement (“ASC 820”), total consideration of $1.2 million for the shares of common stock from the Securities Purchase Agreement, which represents the premium of $0.7 million and discount for lack of marketability of $0.5 million, has been allocated to revenue and will be recognized over the two year expected performance period.

Removed paragraphs (7)

Previous report

Based on the MAD data and additional work we have conducted with RLYB116, we believe that RLYB116 has the potential to be an effective treatment for patients with certain complement-mediated diseases, including gMG. We have prioritized enhancements to the manufacturing process that are intended to improve tolerability at higher doses with a low injection volume and infrequent SC administration, thereby opening up the opportunity to treat a wider range of complement-mediated diseases in addition to gMG including PNH and APS. We expect the manufacturing work to be completed in the second half of 2024.

Previous report

▪a $1.5 million increase in payroll and personnel-related costs, primarily related to severance costs incurred in connection with the workforce reduction, effective March 6, 2024.

Previous wording

We are a clinical-stage biotechnology company comprised of experienced biopharma industry leaders with extensive research, development, and rare disease expertise with a mission to develop and commercialize life-transforming therapies for patients with severe and rare diseases. Since our launch in January 2018, we have built a broad pipeline of promising product candidates aimed at addressing diseases with unmet medical need in the areas of maternal fetal health, complement dysregulation, hematology, and metabolic disorders. Our two most advanced programs are in clinical development: RLYB212, an anti-HPA-1a antibody for the prevention of fetal and neonatal alloimmune thrombocytopenia ("FNAIT") and RLYB116, an inhibitor of complement component 5 (“C5"), with the potential to treat several diseases of complement dysregulation. Both programs have completed Phase 1 clinical studies, and we currently plan to initiate a Phase 2 clinical trial of RLYB212 in the second half of 2024.

Previous wording

Both the FDA and EMA have designated RLYB212 as an orphan drug. Orphan drug designations offer certain incentives including tax credits, marketing exclusivity upon any approval, fee waivers, and the ability to interact with both agencies to receive specialized regulatory advice and assistance. We engaged with the EMA in such a process in advance of our planned Phase 2 clinical trial. We received feedback from the EMA and are now moving forward with our Clinical Trial Application to support conduct of the Phase 2 trial in Europe.

We are also conducting a prospective, non-interventional, multinational FNAIT natural history study. This study is designed to screen up to 30,000 pregnant women presenting at the Gestational Week 10 to 14 prenatal visit to determine the frequency of women at higher FNAIT risk among pregnant women of different racial and ethnic characteristics, as well as the frequency of HPA-1a alloimmunization and pregnancy outcomes among these women. Subject to discussion with regulatory authorities, we expect that data from this study will contribute to a control dataset for a future single-arm Phase 3 registrational trial for RLYB212. The FNAIT natural history study will also operationalizede novo the laboratory test paradigm for FNAIT risk and generate FNAIT laboratory test performance data that we plan to use for future regulatory discussions. As of May 1, 2024, Rallybio has screened approximately 10,000 pregnant women. The Company expects screening for the natural history study to continue simultaneously with execution of the Phase 2 trial.

Previous wording

In May 2022, we obtained worldwide exclusive rights to RLYB331, a preclinical, monoclonal antibody that is designed to inhibit Matriptase-2 ("MTP-2"). The inhibition of MTP-2 significantly increases levels of hepcidin, decreases iron load and treats ineffective erythropoiesis. In the first quarter of 2024, we completed nonclinical studies that demonstrated favorable tolerability, dose-dependent PK and sustained PD effects with RLYB332, a long-acting version of the RLYB331 anti-Matriptase-2 antibody. These findings support the continued development of RLYB332 as a potentially best-in-class therapeutic for treating diseases of iron overload. We anticipate presentation of this data in the second half of 2024. We continue to evaluate non-dilutive options to further advance this program, including potential partnerships.
