NEW HAVEN, Conn.--(BUSINESS WIRE)-- Rallybio Corporation (Nasdaq: RLYB), a clinical-stage biotechnology company translating scientific advances into transformative therapies for patients with devastating rare diseases, today reported first quarter financial results for the period ended March 31, 2024 and provided an update on recent company developments.

“This year is off to a strong start as we continue to progress towards the initiation of our Phase 2 dose confirmation trial for RLYB212 in pregnant women at higher risk of FNAIT, which is on track for the second half of 2024," said Stephen Uden, M.D., Chief Executive Officer of Rallybio. "Last month, we were particularly pleased to announce our collaboration with Johnson & Johnson, marking a significant step forward in our mission to eliminate FNAIT and its devastating consequences. Together with Johnson & Johnson, we look forward to further driving awareness of FNAIT, emphasizing the importance of screening for FNAIT risk, and advancing our complementary therapeutic approaches, which aim to ensure all pregnant women at risk of FNAIT have a potential treatment option regardless of their alloimmunization status."

Dr. Uden continued, "In the near-term, we look forward to sharing initial data from an epidemiologic analysis investigating the genetic markers of FNAIT risk in a racially and ethnically diverse population beyond the Caucasian population, where FNAIT risk has been better established in published literature. This analysis will more accurately inform the number of pregnant women at higher risk for FNAIT annually. We expect that these data combined with data from our ongoing FNAIT natural history study will further emphasize the need for a preventative therapeutic and identify a market opportunity for RLYB212 that is larger than our current estimates."

Recent Business Highlights and Upcoming Milestones:

Corporate Updates

  • In April 2024, Rallybio announced a collaboration with Momenta Pharmaceuticals, Inc., a Johnson & Johnson Company, to advance complementary therapeutic solutions for pregnant women at risk of fetal and neonatal alloimmune thrombocytopenia (FNAIT). Rallybio received an equity investment of $6.6 million from Johnson & Johnson Innovation – JJDC, Inc.
  • In February 2024, Rallybio announced a prioritization of its portfolio and a 45% workforce reduction to focus the Company’s resources on its two Phase 2 ready assets, RLYB212, a novel human monoclonal anti-HPA-1a antibody in development for the prevention of FNAIT, and RLYB116, a once-weekly, low volume subcutaneously injected inhibitor of complement component 5 (C5) in development for patients with complement-mediated diseases.

RLYB212 Program

  • Rallybio is on track to initiate a Phase 2 trial in pregnant women at higher risk for HPA-1a alloimmunization and FNAIT in the second half of 2024. The primary objectives of this trial are to assess the pharmacokinetics and safety of subcutaneously administered RLYB212 in pregnant women. Secondary objectives include assessments of pregnancy and neonatal outcomes, and the occurrence of emergent HPA-1a alloimmunization. Administration of RLYB212 will be initiated by Gestational Week 16 and continue every 4 weeks through parturition.
  • Screening in the Company's FNAIT natural history study is ongoing. This study is designed to provide a contemporary dataset for HPA-1a alloimmunization frequency in a racially and ethnically diverse population. As of May 1, 2024, Rallybio has screened approximately 10,000 pregnant women. The FNAIT natural history study is designed to run in parallel with the Phase 2 study and to continue through to initiation of the planned Phase 3 trial to enable seamless transition of participating sites into the registration trial.
  • To better understand the frequency of HPA-1a-negative, HLA-DRB3*01:01-positive status in a broad and diverse population, Rallybio partnered with HealthLumen, a leader in epidemiological modeling of rare genetic diseases, to conduct an epidemiologic analysis utilizing information from large genomic datasets. Rallybio expects data from this analysis to be disclosed in mid-2024.
  • Several presentations and publications are expected in the second half of 2024, including additional data from the Phase 1b proof-of-concept study and an integrated summary of clinical and nonclinical data supporting the RLYB212 Phase 2 dose.

RLYB116 Program

  • RLYB116 manufacturing work continues and is on track to complete in the second half of 2024. Furthermore, additional biomarker development work is underway to further evaluate results of the Phase 1 multiple ascending dose (MAD) study, which was completed in the fourth quarter of 2023. Rallybio expects to provide an update on this analysis and future development plans for RLYB116 in the second half of 2024.

Preclinical Programs

Rallybio continues to believe that its preclinical programs have the potential to address significant existing unmet needs for patients and caregivers and bring meaningful value to stakeholders. Given Rallybio's focus of current capital and resources on its clinical-stage assets, primarily RLYB212, the Company is seeking alternative options to further advance its preclinical programs, including partnerships and other forms of non-dilutive financing.

  • RLYB332: In the first quarter of 2024, Rallybio completed nonclinical studies that demonstrated favorable tolerability, dose-dependent pharmacokinetics, and sustained pharmacodynamic 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. Presentation of this data is expected in the second half of 2024.
  • RLYB114, EyePoint Collaboration: EyePoint has demonstrated feasibility for sustained delivery of Rallybio’s inhibitor of C5 using EyePoint’s proprietary intraocular drug delivery technology, and optimization work is ongoing.

First Quarter 2024 Financial Results

  • Research & Development (R&D) Expenses: R&D expenses were $12.9 million for the first quarter of 2024, compared to $11.2 million for the same period in 2023. The increase in R&D expense was primarily due to an increase in payroll and personnel-related costs, largely related to severance costs incurred in connection with the workforce reduction, effective March 6, 2024. The increase was partially offset by a decrease in costs related to the development of RLYB212.
  • General & Administrative (G&A) Expenses: G&A expenses were $6.9 million for the first quarter of 2024, compared to $7.2 million for the same period in 2023. The decrease in G&A expense was primarily related to decreases in other general and administrative related expenses and director and officer insurance premiums. This decrease was partially offset by an increase in payroll and personnel-related costs, primarily related to severance costs incurred in connection with the workforce reduction, effective March 6, 2024.
  • Net Loss and Net Loss Per Common Share: Rallybio reported a net loss of $19.0 million, or $0.47 per common share, for the first quarter of 2024. This compares to a net loss of $17.3 million, or $0.43 per common share, for the first quarter of 2023.
  • Cash Position: As of March 31, 2024, cash, cash equivalents, and marketable securities were $94.2 million.
