> Hansoh’s HS-20093 builds on GSK’s oncology portfolio of clinical-stage antibody-drug conjugates, following earlier agreement for Hansoh’s HS-20089 focused on gynaecologic cancers

> HS-20093 has shown promising initial clinical activity in lung cancer with potential to address unmet medical need in broader solid tumour indications


GSK plc (LSE/NYSE: GSK) and Hansoh Pharma (HKEX: 03692), a Chinese biopharmaceutical company committed to discovering and developing life-changing medicines to help patients conquer serious diseases and disorders, today announced that they have entered into an exclusive license agreement for HS-20093, a B7-H3 targeted antibody-drug conjugate (ADC) utilising a clinically validated topoisomerase inhibitor (TOPOi) payload. Under the agreement, GSK will obtain exclusive worldwide rights (excluding China’s mainland, Hong Kong, Macau, and Taiwan) to progress clinical development and commercialisation of HS-20093.

Hesham Abdullah, SVP, Global Head Oncology, R&D, GSK, said: “B7-H3 is highly expressed in a broad range of solid tumours where there remains a significant need for novel treatment options. We look forward to progressing this potential new treatment across several indications and in future potential combination approaches with our established portfolio.”

This agreement provides GSK with a second clinical-stage ADC that complements GSK’s existing capabilities and strengths in developing medicines to address unmet medical needs in various solid tumours. HS-20093 is currently being investigated in ongoing phase I and II trials in China. Data from the ARTEMIS-001 phase I trial (NCT05276609), for HS-20093 in advanced solid tumours, was presented at the 2023 American Society of Clinical Oncology (ASCO) annual meeting in which initial clinical activity was observed in small cell lung cancer, non-small cell lung cancer and sarcoma with multiple confirmed responses and a manageable safety profile.1

Eliza Sun, Executive Director of Board, Hansoh Pharma, said: “HS-20093 is a novel B7-H3 targeting antibody-drug conjugate showing encouraging early clinical signals in lung cancer. We are excited to enter this new license agreement with GSK, our existing licensee on HS-20089, furthering Hansoh’s goal of bringing a potentially transformative treatment option to cancer patients globally.”

GSK plans to begin phase I trials for HS-20093 outside of China in 2024.

In October 2023, GSK and Hansoh entered into an agreement for HS-20089, a B7-H4 targeted ADC currently in phase II clinical trials in China. HS-20089 has best-in-class potential in ovarian and endometrial cancer with opportunities in other solid tumours.


Terms of the agreement

Under the terms of this agreement, GSK will pay $185 million upfront. In addition, Hansoh will be eligible to receive up to $1.525 billion in success-based milestones for HS-20093. Upon commercialisation of HS-20093, GSK will pay tiered royalties on global net sales outside of China’s mainland, Hong Kong, Macau, and Taiwan.

This agreement is subject to customary conditions, including applicable regulatory agency clearances under the Hart-Scott-Rodino Act in the US.
