Pharmacokinetics, Pharmacodynamics, Bioavailability, and Immunogenicity of Obexelimab Following Subcutaneous Administration in Healthy Japanese and Non-Japanese Volunteers

Article

作者: Quinn, Shauna ; Arora, Sujata ; Matijevic, Mark ; Gao, Minggeng ; Kirk, Rachel ; Poma, Allen ; Fischer, Tanya ; Wang, Xiaodong

INTRODUCTION:

Obexelimab is an investigational, bifunctional, non-depleting, humanized monoclonal antibody that binds CD19 and FcγRIIb to inhibit B cells, plasmablasts, and CD19-expressing plasma cells. In clinical trials, intravenous (IV) administration of obexelimab has been well-tolerated, and demonstrated clinical activity in patients with rheumatoid arthritis, systemic lupus erythematosus, and immunoglobulin G4-related disease. This study was performed to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of obexelimab following subcutaneous (SC) administration, and compare PK/PD profiles between healthy Japanese and non-Japanese volunteers.

METHODS:

This was a Phase I, open-label, parallel group, multiple-dose study. Participants were randomized to five cohorts to receive three doses of obexelimab as 125 mg SC every 14 days (q14d), 250 mg SC q14d, 375 mg SC q14d, 250 mg IV q14d, and 125 mg SC every 7 days, then monitored during a 28-day safety follow-up period. PK/PD assessments were performed after the first and third doses.

RESULTS:

A total of 50 healthy volunteers (25 Japanese and 25 non-Japanese) were enrolled and distributed evenly between dose cohorts. All SC dosing regimens were well-tolerated. Dose-proportional PK was observed following SC doses with a bioavailability of approximately 60%. No clinically meaningful differences in PK parameters were found between healthy Japanese and non-Japanese participants. Antidrug antibodies (ADA) were detected in 6/50 (12%) participants after dosing. ADA had no or minimal impact on PK in all six ADA positive participants. Near-complete CD19 receptor occupancy and an absolute B-cell count nadir of approximately 50% baseline levels were maintained for the duration of the study in both populations.

CONCLUSION:

Obexelimab SC administration demonstrated favorable bioavailability, was well-tolerated, and showed no clinically meaningful ethnic differences in PK/PD. These results support further clinical development of SC obexelimab to treat B-cell mediated autoimmune diseases.

Antibody based therapeutics for autoimmune hemolytic anemia

Review

作者: Fattizzo, Bruno ; Cavallaro, Francesca ; Barcellini, Wilma

INTRODUCTION:

Autoimmune hemolytic anemia (AIHA) treatment has been revolutionized by the introduction of target therapies, mainly monoclonal antibodies (MoAbs).

AREAS COVERED:

The anti-CD20 rituximab, which targets Ab production by B-cells, induces 80% of response in warm-type AIHA (wAIHA) and 50-60% in cold agglutinin disease (CAD). Other B-cell targeting MoAbs including ianalumab, povetacicept, and obexelimab are under active study. The anti-CD38 MoAb daratumumab has been used in several reports to target long-lived plasma-cells responsible for AIHA relapse, being effective even in multi-refractory cases. Anti-complement MoAbs will soon change the treatment paradigm in CAD; the anti-C1s sutimlimab rapidly increased Hb in more than 80% of the cases. Finally, MoAbs inhibiting the neonatal Fc receptor (FcRn), such as nipocalimab, can reduce the half-life of the pathogenic autoAbs, representing a promising treatment for wAIHA.

EXPERT OPINION:

MoAbs offer the potential to improve efficacy by reducing toxicity. However, there is a huge need for clinical trials exploring response duration rather than short-term efficacy. Complement inhibitors and anti-FcRns do not abrogate autoAb production and are being developed as long-term therapies. Thus, the combination of B-cell/plasma cell targeting drugs deserves to be explored. On the other hand, their rapid efficacy should be exploited for the acute AIHA phase.

Obexelimab in Systemic Lupus Erythematosus With Exploration of Response Based on Gene Pathway Co‐Expression Patterns: A Double‐Blind, Randomized, Placebo‐Controlled, Phase 2 Trial

Article

作者: Khosroshahi, Arezou ; James, Judith A ; Rathi, Gaurav ; Koumpouras, Fotios ; Askanase, Anca ; Arora, Sujata ; Guthridge, Joel ; Matijevic, Mark ; June, Joshua ; Merrill, Joan T ; Burington, Bart ; Zack, Debra J ; Wax, Stephen ; Smith, Miles ; Foster, Paul ; Machua, Wambui ; Wang, Xiaodong ; Gao, Minggeng ; Sheikh, Saira Z

Objective:

Obexelimab is an investigational, bifunctional, noncytolytic monoclonal antibody that binds CD19 and FcyRIIb to inhibit B cells, plasmablasts, and plasma cells. This trial evaluated the efficacy and safety of obexelimab in the treatment of patients with systemic lupus erythematosus (SLE).

Methods:

During screening, patients with active, non–organ‐threatening SLE received corticosteroid injections to ameliorate symptoms while immunosuppressants were withdrawn (≤10 mg/day prednisone equivalent and ≤400 mg/day hydroxychloroquine allowed). Patients with improved disease activity were randomized 1:1 to obexelimab 5 mg/kg intravenously or placebo once every 2 weeks until week 32 or loss of improvement (LOI).

Results:

In this study, 104 patients were randomized. Analysis of the primary endpoint, proportion of patients reaching week 32 without LOI, used an efficacy‐evaluable (EE) population defined as patients who completed the study or withdrew for flare or treatment‐related toxicity. This endpoint did not reach statistical significance: 21 of 50 obexelimab‐treated patients (42.0%) versus 12 of 42 patients (28.6%) treated with a placebo (P = 0.183). Time to LOI was increased in obexelimab‐treated patients versus patients treated with a placebo in the EE (hazard ratio [HR] 0.53, P = 0.025) and intention‐to‐treat (HR 0.59, P = 0.062) populations. In obexelimab‐treated patients, B cells decreased approximately 50%, and trough concentration and inclusion in baseline gene expression clusters with high B cell pathway modules were associated with increased time to LOI. Obexelimab was associated with infusion reactions but was generally safe and well‐tolerated.

Conclusion:

Although the primary endpoint was not reached, secondary analysis showed time to LOI was significantly increased in obexelimab‐treated patients, and analysis of patient subsets defined by gene expression patterns at baseline suggests a responding subpopulation.image

Royalty bestows Zenas with $300M deal to push autoimmune asset across FDA finish line

Royalty Pharma will rake in 5.5% of worldwide net sales as well as some other undisclosed payments connected to obexelimab’s commercialization.\n Zenas BioPharma has secured up to $300 million from Royalty Pharma in return for royalties on sales of lead autoimmune candidate obexelimab. The cash is intended to help Zenas get its star asset across the phase 3 finish line in IgG4-related disease and into commercialization, the companies announced in a Sept. 2 release.Royalty is bestowing Zenas with a $75 million upfront payment, with more $75 million payouts available if Zenas’ phase 3 trial succeeds and if obexelimab is approved by the FDA for IgG4-RD and systemic lupus erythematosus. IgG4-RD top-line data are expected by the end of the year, Zenas said in the release, and obexelimab is currently in a phase 2 trial for SLE that should read out in the middle of next year.The initial payment should sustain Zenas’ operations through the first quarter of 2027, according to the release.In return, Royalty will rake in 5.5% of worldwide net sales as well as some other undisclosed payments connected to obexelimab’s commercialization.“This transaction underscores our conviction in the potential of obexelimab as a franchise molecule and provides us with financial flexibility to rapidly advance our clinical programs and fund the commercial launch of obexelimab if approved for the treatment of IgG4-RD,” Zenas CEO and founder Lonnie Moulder said in the release. Zenas is also putting obexelimab through its paces in a phase 2 multiple sclerosis trial, with data expected early in the fourth quarter of 2025.While Zenas has two other pipeline programs, ZB002 and ZB004, obexelimab is the Massachusetts-based biotech’s only asset in publicly disclosed clinical trials. Zenas bought exclusive global rights to the candidate in 2021 from Xencor in a deal worth as much as $480 million. In September 2023, Zenas snagged $50 million upfront from Bristol Myers Squibb in exchange for the right to develop and commercialize obexelimab in Asia and Australia.

(“Zenas” or the “Company”) (Nasdaq: ZBIO), a clinical-stage global biopharmaceutical company committed to being a leader in the development and commercialization of transformative therapies for autoimmune diseases, today reported financial results for the second quarter ended June 30, 2025, and provided recent corporate updates. “We are very pleased with the rapid advancement of our broad obexelimab development program, including the completion of enrollment for the Phase 2 MoonStone trial in patients with Relapsing Multiple Sclerosis this past quarter. We look forward to reporting the results from the primary analysis of the trial, and importantly, the topline results from the Phase 3 INDIGO trial of obexelimab in patients with IgG4-RD,” said Lonnie Moulder, Founder and Chief Executive Officer of Zenas. “Given the differentiated profile of obexelimab, along with our extensive development capabilities and commercialization experience, we are well positioned to execute on the significant opportunity ahead to potentially impact the lives of patients living with autoimmune diseases worldwide.” Recent corporate highlights Obexelimab, a CD-19 x FcγRIIb inhibitor of B cell function Immunoglobulin G4-Related Disease (IgG4-RD): Advanced the Phase 3 INDIGO trial, a global registration-directed, multicenter, randomized, double-blind, placebo-controlled trial, to evaluate the efficacy and safety of obexelimab in patients with IgG4-RD. INDIGO is the largest clinical trial conducted in patients living with IgG4-RD to date. Target enrollment of the INDIGO trial concluded in November 2024, and Zenas expects to report topline results around year-end 2025. Relapsing Multiple Sclerosis (RMS): Completed enrollment of the Phase 2 MoonStone trial, a multicenter, randomized, double-blind, placebo-controlled trial, to evaluate the efficacy and safety of obexelimab in patients with RMS. Zenas expects to report results from this trial, including the 12-week primary endpoint results, early in the fourth quarter of 2025.Systemic Lupus Erythematosus (SLE): Continued enrollment of the Phase 2 SunStone trial, a multicenter, randomized, double-blind, placebo-controlled trial to evaluate the efficacy and safety of obexelimab in patients with SLE. Zenas expects to complete enrollment of the Phase 2 SunStone trial by year-end 2025 and report topline results in mid-2026. Second quarter 2025 financial results As of June 30, 2025, the Company’s cash, cash equivalents and investments were $274.9 million. The Company expects that its cash, cash equivalents and investments, as of June 30, 2025, will fund its operating expenses and capital expenditure requirements into the fourth quarter of 2026.Research and development (R&D) expenses were $43.0 million for the quarter ended June 30, 2025, compared to $33.8 million for the quarter ended June 30, 2024. The increase of $9.2 million in R&D expenses primarily relates to an increase in costs related to the clinical development of obexelimab and an increase in personnel costs partially offset by a decrease in costs related to our partnered programs.General and administrative (G&A) expenses were $12.1 million for the quarter ended June 30, 2025, compared to $5.9 million for the quarter ended June 30, 2024. The increase of $6.2 million in G&A expenses was due to an increase in personnel costs, including stock-based compensation expense, pre-commercialization activities including hiring and other expenses associated with operating as a public company.Net loss was $52.2 million for the quarter ended June 30, 2025, compared to net loss of $38.0 million for the quarter ended June 30, 2024. About ObexelimabObexelimab is a bifunctional monoclonal antibody designed to bind both CD19 and FcγRIIb, which are broadly present across B cell lineage, to inhibit the activity of cells that are implicated in many autoimmune diseases without depleting them.
