Rhea-AI Filing Summary

AbCellera Biologics Inc. reported first quarter 2026 results and highlighted positive interim Phase 1 data for its lead program ABCL635. Revenue rose to $8.3 million from $4.2 million in Q1 2025, while net loss narrowed slightly to $43.2 million or $(0.14) per share.

The company increased research and development spending to $46.7 million and reduced sales, general and administrative expenses to $12.3 million. AbCellera ended the quarter with approximately $655 million in total available liquidity, including $531 million in cash, cash equivalents and marketable securities and about $124 million in non‑dilutive government funding.

Interim Phase 1 data for ABCL635, a potential first‑in‑class antibody targeting NK3R for menopausal vasomotor symptoms, showed a favorable tolerability profile with no serious adverse events or liver toxicity, an estimated half‑life of about 24 days supporting once‑monthly dosing, and strong, sustained suppression of testosterone, follicle‑stimulating hormone and luteinizing hormone as biomarkers of target engagement. These findings supported advancing ABCL635 into a Phase 2 trial in postmenopausal women, with topline efficacy data expected in Q3 2026.

Positive

  • None.

Negative

  • None.

Insights

Stronger revenue, solid cash and encouraging Phase 1 data support AbCellera’s 2026–2027 pipeline plans.

AbCellera nearly doubled Q1 2026 revenue to $8.3 million from $4.2 million, while keeping net loss roughly flat at $43.2 million. R&D rose to $46.7 million, reflecting heavier investment in its internal pipeline as SG&A fell to $12.3 million.

Liquidity remains a key strength: the company reported $531 million in cash, cash equivalents and marketable securities plus about $124 million in available non‑dilutive government funding, totaling roughly $655 million. This provides runway to fund multiple programs, including ABCL635, ABCL575, ABCL688 and ABCL386.

Clinically, interim Phase 1 data for ABCL635 showed no serious adverse events or liver toxicity, and an estimated half‑life of about 24 days that supports once‑monthly subcutaneous dosing. Dose‑dependent, sustained suppression of testosterone, FSH and LH in healthy volunteers indicates robust NK3R target engagement. With Phase 2 topline vasomotor symptom data planned for Q3 2026, subsequent disclosures will clarify whether the biomarker profile translates into meaningful clinical benefit.

ABCL635 half-life ~24 days Estimated mean terminal half-life in Phase 1 SAD/MAD
vasomotor symptoms medical
"for the treatment of moderate-to-severe vasomotor symptoms (VMS) associated with menopause"
Vasomotor symptoms are sudden feelings of intense heat, often with sweating and rapid heartbeat, commonly known as hot flashes and night sweats; they occur when the body’s mechanism for controlling blood vessel widening and narrowing becomes unstable. Investors should care because these symptoms affect large patient groups and drive demand for treatments, influence clinical trial design and regulatory decisions, and can materially affect sales and market value of therapies addressing quality-of-life conditions—think of them as a thermostat malfunction that creates a clear medical market need.
Phase 1 medical
"positive interim results from the Phase 1 portion of its ongoing Phase 1/2 clinical trial of ABCL635"
Phase 1 is the first stage of testing a new drug or medical treatment in people, focused primarily on safety, how the body handles the product, and finding a tolerated dose. Think of it as a short, tightly controlled experiment with a small group to check for dangerous side effects before wider testing; for investors it is an early milestone that reduces some uncertainty but still carries high risk and potential for both big value changes and setbacks.
G protein-coupled receptor medical
"Target Type G protein-coupled receptor (GPCR)"
A G protein-coupled receptor is a protein on a cell’s surface that acts like an antenna: it detects signals such as hormones, neurotransmitters or drugs outside the cell and passes that message inside to change cell behavior. Investors care because roughly a third of marketed medicines act on these receptors, so a company’s success in targeting or modulating a specific receptor can determine the value of drug candidates, regulatory risk, and future revenue potential.
non-dilutive government funding financial
"approximately $124 million in available non-dilutive government funding"
Non-dilutive government funding is money a company receives from a government—such as grants, contracts, tax credits, or low-interest loans—that does not require issuing new shares or giving up ownership. For investors, it matters because it funds growth or R&D without shrinking existing shareholders’ stake, extending a company’s cash runway and reducing the need to sell equity; think of it as a subsidy or loan that preserves ownership while de-risking projects.
total available liquidity financial
"bringing total available liquidity to approximately $655 million to execute on AbCellera's strategy"
The total amount of cash, short-term investments and other funding a company can access quickly — including unused credit lines and committed financing — that can be used to meet obligations or seize opportunities on short notice. Investors watch this like a household’s combined bank balance and available credit: it shows how easily the company can pay bills, ride out revenue drops or fund short-term growth, so low liquidity raises the risk of financial stress.
randomized, double-blind, placebo-controlled medical
"a randomized, double-blind, placebo-controlled study designed to evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics"
A "randomized, double-blind, placebo-controlled" process is a method used to test the effectiveness of a new treatment or intervention. Participants are randomly assigned to different groups, with one receiving the real treatment and the other a fake version, called a placebo. Neither the participants nor the researchers know who is receiving which, which helps ensure unbiased results. For investors, this rigorous approach increases confidence that the findings are accurate and not influenced by guesswork or bias.

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.

FAQ

How did AbCellera (ABCL) perform financially in Q1 2026?

AbCellera’s Q1 2026 revenue was $8.3 million, up from $4.2 million in Q1 2025. The company reported a net loss of $43.2 million, or $(0.14) per basic and diluted share, slightly improving from a $45.6 million loss a year earlier.

What is AbCellera’s liquidity position as of March 31, 2026?

AbCellera ended Q1 2026 with $531 million in cash, cash equivalents and marketable securities, plus about $124 million in available non‑dilutive government funding. This brought total available liquidity to approximately $655 million to support its research, clinical programs, and corporate strategy.

What are the key Phase 1 results for AbCellera’s ABCL635 program?

Interim Phase 1 data for ABCL635 showed a favorable tolerability profile with no serious adverse events or liver toxicity and generally mild, transient adverse events. The antibody demonstrated an estimated ~24‑day half‑life and strong, sustained suppression of testosterone, FSH, and LH, indicating robust NK3R target engagement.

What is ABCL635 and what condition is AbCellera targeting?

ABCL635 is a potential first‑in‑class antibody targeting neurokinin 3 receptor (NK3R). AbCellera is developing it as a non‑hormonal treatment for moderate‑to‑severe vasomotor symptoms (hot flashes) associated with menopause, aiming for once‑monthly subcutaneous dosing and a differentiated safety profile.

What are the plans for ABCL635 Phase 2 and expected milestones?

Based on Phase 1 data, AbCellera advanced ABCL635 into a Phase 2 randomized, double‑blind, placebo‑controlled trial in about 80 postmenopausal women with moderate‑to‑severe vasomotor symptoms. The study evaluates a single 600 mg subcutaneous dose, with topline efficacy and safety data expected in Q3 2026.

How is AbCellera’s broader pipeline progressing beyond ABCL635?

AbCellera reported that ABCL635 and ABCL575 are progressing through clinical trials, while ABCL386 and ABCL688 are in IND‑enabling activities. The company also held downstream stakes in 14 molecules in the clinic and 40 partner‑led programs believed to be progressing at the end of Q1 2026.
