NEWS RELEASE
AbCellera Reports Q1 2026 Business Results & Announces Positive Interim Phase 1 Clinical Data for ABCL635
5/11/2026
•ABCL635 demonstrated a favorable tolerability profile, with no observed liver toxicity, and achieved potent and sustained reductions in biomarkers of target engagement.
•Ended Q1 2026 with total available liquidity of approximately $655 million.
VANCOUVER, British Columbia--(BUSINESS WIRE)-- AbCellera (Nasdaq: ABCL) today announced financial results for the first quarter of 2026 and positive interim results from the Phase 1 portion of its ongoing Phase 1/2 clinical trial of ABCL635. ABCL635 is a potential first-in-class antibody targeting the neurokinin 3 receptor (NK3R) for the treatment of moderate-to-severe vasomotor symptoms (VMS) associated with menopause. All financial information in this press release is reported in U.S. dollars, unless otherwise indicated.
“We are excited to share interim Phase 1 data that show ABCL635 achieved robust NK3R target engagement at doses that were well-tolerated in healthy volunteers and a pharmacokinetic profile that may support a once monthly dosing regimen. We look forward to the efficacy readout from the Phase 2 data in Q3, which we believe will be highly de-risking for the program,” said Carl Hansen, Ph.D., founder and CEO of AbCellera. “Through 2026 we are focused on delivering data readouts for our clinical programs, advancing ABCL688 and ABCL386 into IND-enabling studies, and selecting at least one additional development candidate. We continue to maintain our strong cash position, ending the quarter with approximately $655 million dollars in available liquidity to execute on our strategy.”
Q1 2026 Business Summary and Program Updates
●ABCL635 and ABCL575 continued to progress through clinical trials.
●ABCL386 and ABCL688 are progressing through IND-enabling activities.
●Generated a net loss of $43.2 million, compared to a net loss of $45.6 million in Q1 2025.
●Ended the quarter with approximately $655 million in total available liquidity to execute on our strategy.
Clinical Update: ABCL635 Interim Phase 1 Data
Study Design
The Phase 1 trial of ABCL635 (NCT07118891) is a randomized, double-blind, placebo-controlled study designed to evaluate single and multiple doses of ABCL635 in healthy volunteers. A total of 40 healthy men and postmenopausal women were enrolled in the single ascending dose (SAD) part and treated with single doses ranging from 30 mg to 900 mg. The multiple ascending dose (MAD) part enrolled a total of 16 postmenopausal women who received multiple once monthly doses ranging from 300 mg to 600 mg.
Study Results
The interim Phase 1 data supported advancing ABCL635 into Phase 2. Data from the MAD part remain blinded, with safety follow-up visits ongoing. The unblinded interim data from the SAD part demonstrated the following:
•A favorable tolerability profile: ABCL635 was well-tolerated across all doses, with no serious adverse events or elevations in liver enzymes. Treatment-emergent adverse events were generally mild and transient.
•A pharmacokinetic profile that supports monthly dosing: ABCL635 exhibited an estimated half-life of ~24 days, supporting the potential for a once monthly subcutaneous dose.
•Strong suppression of biomarkers of target engagement: To confirm target engagement of NK3R on kisspeptin, neurokinin B, and dynorphin (KNDy) neurons in the infundibular nucleus of the hypothalamus, testosterone, a clinically validated surrogate biomarker of NK3R antagonism, was measured in male volunteers. ABCL635 demonstrated sustained and dose-dependent suppression of testosterone over a four-week period.
Based on these data, AbCellera advanced ABCL635 into a Phase 2 study, as announced earlier this year. The Phase 2 is a multicenter, randomized, double-blind, placebo-controlled trial with approximately 80 postmenopausal women designed to evaluate the efficacy of ABCL635 in reducing the frequency and severity of moderate-to-severe VMS.
