Detailed Narrative
ABCL635 Phase II Progress and Expectations
The Phase II study for ABCL635, targeting moderate to severe hot flashes associated with menopause, completed enrollment and initial dosing in June, ahead of schedule. Top-line data is expected very soon. Management believes positive data would highly derisk the program, with success defined by a clean safety profile and efficacy comparable to approved small molecules, particularly a 20% response rate and reduction of at least two hot flashes per day in frequency. The company also plans to evaluate ABCL635 for VMS associated with cancer treatment.
T Cell Engager Platform Development and Partnerships
AbCellera has invested five years in developing its T cell engager (TCE) platform, which now includes diverse CD3 and co-stimulatory antibody panels, scalable engineering workflows, and in vitro assays. This comprehensive toolkit has enabled two new significant collaborations with Vertex and Jazz Pharmaceuticals, adding over $110 million in upfront cash and potential for billions in downstream payments. These partnerships validate the platform's capability for developing multi-specific TCEs across oncology and autoimmunity.
Jazz Pharmaceuticals Collaboration Details
The collaboration with Jazz Pharmaceuticals includes three confirmed discovery programs, with $84 million in total near-term upfront payments. AbCellera has already received $56 million for the first two programs and expects another $28 million for the third program within 12 months. The deal has a potential total value of over $2 billion in downstream payments and mid-single-digit to low double-digit tiered royalties, with options for two additional programs, potentially increasing the total deal value to over $4 billion.
Vertex Collaboration Details
AbCellera's collaboration with Vertex focuses on TCEs for autoimmune diseases. Under the terms, AbCellera will receive $28 million in upfront payments and is eligible for potential downstream payments and tiered royalties on net sales. The agreement also includes a potential option for AbCellera to conduct process development and clinical manufacturing for Vertex.
Financial Position and Liquidity
AbCellera maintains a strong liquidity position, ending the quarter with $567 million in cash and marketable securities, a $6 million increase in the first half of 2026. Including available committed government funding, total available liquidity exceeds $675 million. The company believes this is sufficient to fund at least the next three years of pipeline investments, despite an increase in R&D expenses to $46 million.
Pipeline Updates (Other Programs)
ABCL-688 and ABCL386 are progressing through IND-enabling activities and are expected to enter Phase I/II studies in 2027. The Phase I trial for ABCL575 completed dosing and is on track for a Q4 readout, though the company has no plans to develop it past Phase I. An internal program missed its H1 timeline for IND-enabling activities but is making good progress.
