Pathos AI, a clinical-stage AI and technology company advancing its own pipeline of cancer therapies, today announced a licensing agreement with Jiangsu Alphamab Biopharmaceuticals Co., Ltd. (“Alphamab”), a wholly-owned subsidiary of Alphamab Oncology (Stock Code: 9966.HK), on JSKN016, a first-in-class (FIC) TROP2/HER3 bispecific antibody-drug conjugate (ADC) independently developed by Alphamab.

Pursuant to the licensing agreement, Alphamab granted Pathos an exclusive license to research, develop, manufacture and commercialize JSKN016 in territories outside the Chinese Mainland, Hong Kong, Macau and Taiwan, with Pathos bearing all related development and commercialization costs and expenses under the agreement. Alphamab retains its full and exclusive rights to develop, manufacture and commercialize JSKN016 in the Chinese Mainland, Hong Kong, Macau and Taiwan.

Under the terms of the agreement, Alphamab is entitled to receive a non-refundable upfront payment of US$125 million and milestone payments based on the achievement of certain development and commercialization milestones, totaling up to US$2,093 million, as well as tiered royalties at high-single digit to low-double digit percentage rates according to aggregate annual net sales in the licensed territories.

Accelerated by AI: The Foundry Advantage

JSKN016 was identified and prioritized through Foundry, Pathos’s proprietary AI-driven decision platform for oncology drug development. Foundry utilizes thousands of AI agents working in parallel, powered by the Pathos’ proprietary AI models, to analyze biological, clinical, and real-world data at scale; surfacing high-potential assets, designing clinical trials, and matching the right patients to the right therapies faster and more safely than traditional methods allow.

Every major asset-level decision at Pathos flows through Foundry. JSKN016 becomes the fourth clinical-stage program advanced into the Pathos pipeline through the platform.

"JSKN016 is a next-generation bispecific ADC with the potential to address significant unmet need across a range of solid tumors, and we are excited to advance it in partnership with Alphamab. This program was identified through Foundry, the same platform that continues to guide portfolio decisions across our clinical pipeline. This collaboration reflects our shared commitment to bringing differentiated therapies to patients."

— Iker Huerga, CEO of Pathos AI

"JSKN016 represents the best of our next-generation bispecific ADC platform, and we are excited to partner with Pathos. With Pathos's leading capabilities in AI-driven precision development, we are confident this collaboration will accelerate the global clinical advancement of JSKN016 and bring a potential breakthrough therapy to more patients with solid tumors. This partnership reflects our shared commitment to delivering differentiated innovation to patients worldwide."

A Growing Mission to Transform Oncology

The addition of JSKN016 expands Pathos’s clinical pipeline to four assets across multiple solid tumor indications. JSKN016, a TROP2/HER3 bispecific ADC, joins pocenbrodib, currently in development for metastatic castration-resistant prostate cancer (mCRPC) and relapsed/refractory multiple myeloma (RRMM); DO-2, for MET-altered non-small-cell lung cancer (NSCLC); and AZD4241, an ERα PROTAC for ER+/HER2- breast cancer being advanced under a collaboration with AstraZeneca. Every program in the Pathos pipeline has been identified, evaluated, or accelerated by the Foundry platform, reinforcing the company’s commitment to AI-native drug development.
