Key Offerings

• RLYB212: RLYB212 is a C5 complement inhibitor being developed for paroxysmal nocturnal hemoglobinuria (PNH) and generalized myasthenia gravis (gMG). While direct market share data is not yet available as the product is in clinical development, competitors include Alexion (acquired by AstraZeneca) and UCB in the C5 complement inhibitor space for PNH and gMG, respectively.
• RLYB211: RLYB211 is an anti-C1s antibody being developed for complement-mediated diseases, including antibody-mediated rejection (AMR) and delayed graft function (DGF). Similar to RLYB212, market share data is unavailable at this stage. Competitors include companies developing complement inhibitors, such as Omeros and Novartis.
• RLYB2601: RLYB2601 is an anti-HPA-1a antibody fragment being developed for fetal and neonatal alloimmune thrombocytopenia (FNAIT). Given that this is currently in early trials there are no directly competing marketed products.

Industry Overview

The biotechnology industry is characterized by high innovation and intense competition. The rare disease market is growing due to increased awareness, improved diagnostics, and regulatory incentives.

Positioning

Rallybio focuses on niche markets within rare diseases where there are unmet medical needs. Their competitive advantage lies in their experienced team and focused therapeutic approach.

Total Addressable Market (TAM)

The TAM for rare diseases is significant, estimated to be in the tens of billions of dollars. Rallybio is focusing on specific subsets within this market. For FNAIT, potential market size is roughly $500M-$1B based on prevalence and per patient cost. For PNH and gMG, total markets are larger, multiple billions of dollars. Rallybio's specific TAM is defined by market share within these conditions.

Key Competitors

• ALXN
• AZN
• UCB
• OMER
• NVS

Competitive Landscape

Rallybio faces competition from established pharmaceutical companies with greater resources. Their advantage lies in their focus on specific rare disease populations.
