BioAge Labs Reports Second Quarter 2025 Financial Results and Provides Business

Updates

Oral NLRP3 inhibitor BGE-102 on track for Phase 1 initiation in 2H 2025 with initial data by year-end

Expanded APJ agonist pipeline through option agreement for novel antibody and advancement of proprietary oral small molecules

Strengthened discovery platform through molecular profiling of 17,000+ samples from leading European HUNT Biobank

EMERYVILLE, Calif.--BioAge Labs, Inc. ("BioAge", “the Company”), a clinical-stage biotechnology company developing therapeutic product candidates for metabolic diseases by targeting the biology of human aging, today provided business updates and reported its second quarter 2025 financial results.

“In Q2 2025, BioAge achieved key milestones across our clinical pipeline and discovery platform,” said Kristen Fortney, CEO and co-founder of BioAge. “We completed IND-enabling studies for our potential best-in-class oral NLRP3 inhibitor, BGE-102, positioning us to initiate Phase 1 trials later this year, with initial SAD data expected by year-end. We strengthened our apelin pipeline by securing a partnership for potent APJ agonist antibodies and filing patent applications for novel oral small molecules. We also launched a collaboration with the HUNT Biobank to generate millions of new data points, fueling our analysis of human longevity. I’m proud of our progress as we advance our mission to develop transformative therapies for metabolic diseases.”

Second Quarter 2025 Business Highlights

NLRP3 inhibitor program development

●

In May 2025, BioAge announced the completion of IND-enabling studies for BGE-102, an orally available, brain-penetrant NLRP3 inhibitor being initially developed for obesity. BGE-102 demonstrated significant weight loss in preclinical models both as monotherapy and in combination with the GLP-1 receptor agonist semaglutide. The Company plans to initiate a Phase 1 SAD/MAD clinical trial in the second half of 2025, with initial single ascending dose (SAD) data anticipated by year-end.

APJ agonist pipeline expansion

●

In June 2025, BioAge entered into an exclusive option agreement with JiKang Therapeutics (“JiKang”) to potentially in-license a novel APJ agonist nanobody (single-domain antibody) that demonstrates at least 10-fold greater potency than apelin, the natural ligand of APJ. Under the agreement, BioAge and JiKang will jointly advance the nanobody to the beginning of IND-enabling studies, with BioAge holding an exclusive, pre-negotiated option to license the program for worldwide development and commercialization across all indications.

●

In May 2025, BioAge filed a U.S. provisional patent application for a new class of orally active, chemically distinct APJ agonists with picomolar potency and drug-like properties including high solubility and metabolic stability.

Discovery platform expansion

●

In June 2025, BioAge announced the launch of an initiative to comprehensively profile and analyze samples from the HUNT Biobank in Norway through its collaboration with Age Labs AS. BioAge will profile more than 17,000 individual samples from 6,000+ participants to generate millions of molecular measurements tracking the transition from health to disease over decades of lifespan. The Company has exclusive access for drug discovery purposes to data generated by the partnership.

Strategic partnerships

●

The Company continued to advance its multi-year research collaboration with Novartis, announced in December 2024, focused on discovering novel therapeutic targets at the intersection of aging biology and exercise physiology, with multiple targets under evaluation.

●

BioAge progressed its strategic collaboration with Lilly ExploR&D, announced in January 2025, for the development of therapeutic antibodies targeting novel metabolic aging targets identified through BioAge's discovery platform.

Second Quarter 2025 Financial Results

Research and development expenses were $19.8 million for the quarter ended June 30, 2025, compared to $10.5 million for the same period in 2024. The $9.3 million increase in research and development expenses was primarily attributable to a $8.0 million increase in direct costs related to licensing, discovery, and development activities related to our novel apelin receptor APJ agonist programs. Additionally contributing to the increase in research and development expenses was a $3.0 million increase in direct costs related to our BGE-102 program associated with IND-enabling activities and drug-product manufacturing. These higher costs were partially offset by a $1.7 million reduction in azelaprag direct costs as development was terminated in January 2025.

General and administrative expenses were $7.3 million for the quarter ended June 30, 2025, compared to $4.8 million for the same period in 2024. The $2.5 million increase was primarily

attributable to a $1.5 million increase in personnel-related expenses, which was largely attributable to increased stock-based compensation expense associated with option grants issued to employees, executives, board members and advisors. Additionally, contributing to the increase was a $0.9 million increase in legal fees.

Net loss was $21.6 million for the quarter ended June 30, 2025, or $0.60 per weighted-average common share outstanding, basic and diluted, compared to a net loss of $13.6 million, or $7.94 per weighted-average common share outstanding, basic and diluted, for the same period in 2024.

As of June 30, 2025, BioAge had approximately $313.4 million in cash, cash equivalents, and marketable securities. Based on our current operating plan, BioAge estimates that existing cash, cash equivalents, and marketable securities will be sufficient to fund operations and capital expenses through 2029.

The Company's lead product candidate, BGE-102, is a potent, orally available, brain-penetrant small-molecule NLRP3 inhibitor being developed for obesity. BGE-102 has demonstrated significant weight loss in preclinical models both as monotherapy and in combination with GLP-1 receptor agonists. Initiation of a Phase 1 SAD/MAD trial is planned for the second half of 2025, with initial SAD data anticipated by end of year. The Company is also developing long-acting injectable and oral small molecule APJ agonists for obesity. BioAge’s additional preclinical programs, which leverage insights from the Company’s proprietary discovery platform built on human longevity data, address key pathways involved in metabolic aging.
