HitGen’s DEL Platform Powers BioAge’s Obesity Drug Into the Clinic
Chengdu, China – HitGen Inc. (SSE: 688222.SH) announced that partner BioAge Labs, Inc. (NASDAQ: BIOA) has begun a Phase 1 clinical trial of BGE-102, a first-in-class NLRP3 inhibitor discovered using HitGen’s DNA-encoded library (DEL) technology. The milestone triggers an undisclosed payment to HitGen under its collaboration with BioAge.
BGE-102: A Novel NLRP3 Inhibitor
Mechanism: Orally available, brain-penetrant small molecule inhibitor of NLRP3 inflammasome.
Indication: Being developed for obesity, with potential applications in neurodegenerative, cardiovascular, and metabolic diseases linked to chronic inflammation.
Preclinical data: Showed significant weight loss as monotherapy and in combination with GLP-1 receptor agonists.
Clinical status: A SAD/MAD Phase 1 trial is ongoing, with initial single-ascending dose data expected by end of 2025.
Collaboration Milestones
April 2021: HitGen and BioAge identified promising NLRP3 hits from DEL screening.
Feb 2024: Joint publication in Bioorganic & Medicinal Chemistry Letters detailing discovery of indazole NLRP3 inhibitors.
2024–2025: Co-filed patents on structurally novel compounds.
Sept 2025: BioAge advances BGE-102 into the clinic, triggering a milestone payment to HitGen.
Leadership Commentary

Company Profiles
HitGen Inc.
Global leader in DNA-encoded library screening, with 1.2 trillion molecules in its libraries.
Platforms: DEL, fragment-based drug discovery, structure-based design, targeted protein degradation, oligonucleotide therapeutics.
NLRP3 inflammasome is emerging as a hot drug target for metabolic, neurodegenerative, and cardiovascular diseases.
Competitors include Inflazome (acquired by Roche) and Novartis, both developing inflammasome inhibitors.
If successful, BGE-102 could provide a novel anti-inflammatory approach to obesity, potentially complementing or competing with GLP-1 therapies like semaglutide.
