BGE-102 was well-tolerated in SAD and initial MAD cohorts, with a pharmacokinetic profile supporting once-daily oral dosing

Strong target engagement: BGE-102 achieved 90-98% suppression of IL-1β, a cytokine directly downstream of NLRP3, at Day 14

High brain penetration: BGE-102 doses of 60 mg and higher exceeded target IC90 levels in cerebrospinal fluid (CSF) at Day 14

Company is expanding the Phase 1 trial to include MAD cohorts in participants with obesity and elevated hsCRP, with data anticipated in first half of 2026

EMERYVILLE, Calif., Dec. 04, 2025 (GLOBE NEWSWIRE) -- BioAge Labs, Inc. (Nasdaq: BIOA) ("BioAge"), a clinical-stage biopharmaceutical company developing therapeutic product candidates for metabolic diseases by targeting the biology of human aging, today announced positive interim data from the ongoing Phase 1 single ascending dose (SAD) / multiple ascending dose (MAD) clinical trial evaluating BGE-102, a potent, structurally novel, orally available, brain-penetrant small molecule NLRP3 inhibitor being developed for treatment of patients with cardiovascular risk factors.

“We’re very encouraged by the interim data from our ongoing Phase 1 trial of BGE-102, an NLRP3 inhibitor with best-in-class potential. Once-daily doses of 60 mg and above were well tolerated and exceeded target IC90 levels in both the periphery and the brain,” said Kristen Fortney, PhD, CEO and co-founder of BioAge. “The clear evidence of high brain penetration is especially important, as it supports BGE-102’s potential to comprehensively target NLRP3-driven inflammation in both the central nervous system and peripheral tissues.”

Key Initial Findings from the Phase 1 Study

Safety & Tolerability

• BGE-102 treatment was well tolerated across all dose levels evaluated to date in SAD (10, 30, 60, and 120 mg) and MAD (60 and 120 mg) cohorts
• Adverse events were infrequent and mild to moderate in severity, and all resolved without intervention; full analysis to follow after database lock and unblinding in the first half of 2026

Pharmacokinetics & Pharmacodynamics

• Dose proportionality observed across doses tested
• BGE-102 treatment achieved 90% (60 mg dose) to 98% (120 mg dose) suppression of IL-1β production in an ex vivo whole blood stimulation assay prior to dosing on Day 14
• In MAD cohorts, treatment with BGE-102 at 60 mg and higher achieved plasma concentrations exceeding IC90 for 24 hours
  

CNS Penetration

• In MAD cohorts, BGE-102 doses of 60 mg and higher resulted in CSF concentrations exceeding the IC90 after 14 days
• High brain penetration is a key differentiator from other NLRP3 inhibitors in development, enabling the targeting of both peripheral and central inflammation

Phase 1 Study Design

The ongoing Phase 1 study is a randomized, double-blind, placebo-controlled trial in healthy volunteers and obese participants. Part 1 evaluated SAD at four dose levels (10, 30, 60, and 120 mg); Part 2 evaluated MAD administered once daily for 14 days in healthy volunteers (60 mg and 120 mg). Pharmacodynamic effects were evaluated using an ex vivo whole blood stimulation assay that measures BGE-102's ability to inhibit production of the key inflammatory signal IL-1β, which is directly downstream of NLRP3.

Part 2 has been expanded to evaluate two dose levels in obese participants with elevated hsCRP. The MAD portion in obese participants is ongoing, with data anticipated in the first half of 2026.

"Recent clinical experience has shown that NLRP3 inhibitors can achieve substantial reductions in inflammatory biomarkers such as hsCRP within the first week of treatment," said Paul Rubin, MD, Chief Medical Officer of BioAge. "Because IL-1β is a key upstream regulator of CRP production, the potent and sustained IL-1β suppression we observed with BGE-102 has the potential to translate directly into meaningful effects on hsCRP. As a result, we have expanded the current trial with additional cohorts of obese participants with elevated baseline inflammation with the goal of providing early potential biomarker proof-of-concept."

Anticipated Milestones

• 1H26: Completion of Phase 1 MAD cohorts in obese participants with elevated hsCRP, evaluating changes in key inflammatory biomarkers including hsCRP and IL-1β
• 1H26: Initiation of Phase 2a proof-of-concept study in patients with obesity and cardiovascular risk factors.
  • The trial is planned to enroll approximately 100 patients randomized 1:1 to placebo or BGE-102 monotherapy for 12 weeks. The anticipated primary endpoint of the trial is percent change in hsCRP. Additionally, the trial will assess a range of inflammatory and metabolic biomarkers, and will include MRI imaging.
• 2H26: Phase 2a data readout

Background on BGE-102 and NLRP3

BGE-102 is a potent, orally available, brain-penetrant small molecule NLRP3 inhibitor being developed for cardiovascular risk factors in patients with obesity. BGE-102 represents a structurally novel class of NLRP3 inhibitors developed by BioAge with a unique mechanism and binding site. NLRP3 is a key driver of age-related inflammation that has been implicated in a broad range of diseases, including cardiovascular disease, neurodegenerative conditions, and metabolic disorders. NLRP3 inhibition is a promising emerging strategy for reducing levels of inflammatory biomarkers associated with cardiovascular risk.
