NEW HAVEN, Conn.--(BUSINESS WIRE)-- Rallybio Corporation (Nasdaq: RLYB) today reported financial results for the third quarter ended September 30, 2023 and provided an update on recent program and corporate developments.

“We are pleased with the continued progress across our portfolio in recent months, further demonstrating the ability of our team to efficiently advance clinical trials across diverse therapeutic areas. Prior to the end of 2023, we expect to finalize the toxicology package for RLYB212, our anti-HPA-1a monoclonal antibody for the prevention of fetal and neonatal alloimmune thrombocytopenia (FNAIT), to support our planned Phase 2 and Phase 3 studies in pregnant women. In addition, we have completed the multiple dose cohort of our ongoing Phase 1 study for RLYB212 and have initiated regulatory discussions for RLYB212 to support the initiation of a Phase 2 dose confirmation study in pregnant women at higher risk for FNAIT. We also look forward to sharing more about the ongoing FNAIT natural history study at the upcoming American Society of Hematology Annual Meeting in December,” said Stephen Uden, M.D., Chief Executive Officer of Rallybio.

Dr. Uden continued, “Our multiple ascending dose Phase 1 study for RLYB116, an inhibitor of complement component 5 (C5), remains on track and we expect to share initial data from this study, including our indication strategy, prior to the end of 2023. In parallel, we continue to advance our preclinical programs albeit with a focus on capital conservation and believe our existing capital will be sufficient to fund our operating expenses and capital expenditure requirements into the first quarter of 2025.”

Maternal Fetal Blood Disorders Rallybio expects to achieve the following milestones in the fourth quarter of 2023 for RLYB212, an anti-HPA-1a monoclonal antibody being developed for the prevention of FNAIT:

  • Finalize toxicology package for RLYB212, including maternal-fetal toxicology to support our planned Phase 2 and Phase 3 studies in pregnant women.
  • Disclose preliminary data for the multiple dose cohort of the Phase 1 safety and pharmacokinetic study of RLYB212.
  • Poster presentation of abstract for the ongoing natural history study at the 65th American Society of Hematology Annual Meeting in December 2023.
  • On track to screen 7,600 women for the natural history study by the end of 2023.

The Company also continues to advance the FNAIT natural history study. This non-interventional study is designed to inform on the frequency of women at higher risk for FNAIT across a broad population of pregnant women of different racial and ethnic characteristics, and the occurrence of HPA-1a alloimmunization in these women. The Company expects screening for the natural history study to continue simultaneously with execution of the Phase 2 dose confirmation study. The Phase 2 study for RLYB212 is expected to initiate in the second half of 2024 and is designed to confirm the dose regimen for RLYB212 in pregnant women at higher risk of FNAIT.

Complement Dysregulation Rallybio remains on track to report initial data in the fourth quarter of 2023 from the Phase 1 multiple ascending dose (MAD) study of RLYB116, a novel, potentially long-acting, subcutaneously injected inhibitor of C5 in development for the treatment of patients with complement-related diseases. This single-blind, dose escalation, placebo-controlled study is designed to evaluate the safety, pharmacokinetics, and pharmacodynamics of RLYB116 in healthy participants. In parallel with the initial data from this study, Rallybio also intends to discuss its plans for potential indications for which RLYB116 could be developed.

In September 2023, clinical data from the Phase 1 first-in-human single ascending dose (SAD) clinical study of RLYB116 were presented in a poster at the 29th International Complement Workshop. The data demonstrated that single-dose administration of RLYB116 at the two higher doses of 100 mg and 300 mg resulted in maximum exposures of greater than 1 µM and 3 µM, respectively, and greater than 99% reductions in free C5 concentrations. Subcutaneously administered RLYB116 was observed to be generally well-tolerated as a single 100 mg or 300 mg dose, with mild to moderate adverse events and no drug-related serious adverse events.

Third Quarter 2023 Financial Results:

  • Research & Development (R&D) Expenses: R&D expenses were $13.3 million for the third quarter of 2023, compared to $12.1 million for the same period in 2022. The increase in R&D expenses was primarily due to an increase in costs to advance RLYB212 and RLYB331 and an increase in R&D related headcount costs, including share-based compensation expense, as compared to the prior year. These costs were offset by a decrease in R&D costs related to RLYB116.
  • General & Administrative (G&A) Expenses: G&A expenses were $6.1 million for the third quarter of 2023, compared to $6.8 million for the same period in 2022. The decrease in G&A expenses was primarily due to a decrease in G&A related payroll and personnel-related costs and director and officer insurance premiums; offset by increases in other general and administrative related expenses.
  • Net Loss and Net Loss Per Common Share: Net loss was $18.4 million for the third quarter of 2023, or net loss per common share of $0.45 compared to a net loss of $18.4 million, or net loss per common share of $0.60 for the third quarter of 2022.
  • Cash Position: As of September 30, 2023, cash, cash equivalents and marketable securities were $121.4 million.
