AbCellera (Nasdaq: ABCL) and Rallybio Corporation (Nasdaq: RLYB) announced today that they have entered into a strategic alliance to discover, develop, and commercialize novel antibody-based therapeutics for rare diseases. This multi-year, multi-target collaboration will combine AbCellera’s antibody discovery engine with Rallybio’s clinical and commercial expertise in rare diseases to identify optimal clinical candidates and ultimately deliver therapies to patients.

“It’s clear that we need to accelerate drug development for rare diseases to address the enormous unmet medical need for these patients,” said Carl Hansen, Ph.D., founder and CEO of AbCellera. “Rallybio’s team has decades of experience in sourcing, identifying, and evaluating therapeutic targets. By bringing together Rallybio’s deep expertise in rare diseases with AbCellera’s integrated technology for delivering clinical leads with unmatched precision and speed, this partnership creates a unique advantage that we believe will deliver new and transformative medicines to patients.”

“AbCellera’s clinically validated discovery engine will strengthen our efforts in identifying novel rare disease candidates to add to our existing pipeline,” said Martin Mackay, Ph.D., Chief Executive Officer of Rallybio. “We are excited to establish this partnership and look forward to working closely with our colleagues at AbCellera as we build novel medicines together.”

Under the terms of the agreement, AbCellera and Rallybio will co-develop up to five rare disease therapeutic targets, which will be chosen together by both companies. The collaboration will allow Rallybio to add product candidates to its existing pipeline and also provides the option for AbCellera to conduct process development and clinical manufacturing activities. The partnership’s first program will focus on addressing the significant unmet therapeutic needs of patients with rare metabolic diseases.
