The AACR Annual Meeting is one of the world’s largest and oldest scientific gatherings dedicated to cancer research. The annual event covers some of the most innovative advances in all areas of oncology research and innovation and generates tremendous interest from the global cancer research community. This year’s AACR Annual Meeting is taking place 14-19 April 2023In OrlandoFloridaUNITED STATES.

These three abstracts from Ascentage Pharma include:

Olverembatinib (HQP1351)
Olverembatinib (HQP1351) Enhances the Antitumor Effect of Immunotherapy in Renal Cell Carcinoma (RCC)

  • Summary number: 5071

  • Title: Immunology

  • Session title: Combination immunotherapies 1

  • session time: Tuesday April 18, 2023, 1:30 p.m. – 5 p.m. EDT

Our results suggest that the combination of olverembatinib with a checkpoint inhibitor (CPI) confers synergistic antitumor effects in an RCC cancer mouse model by targeting tumor growth, angiogenesis, and immune regulation. This novel combination could offer an alternative approach to improve the treatment effects of CPIs in kidney cancer.

Olverembatinib (HQP1351) plus lisaftoclax (APG-2575)
Combination of Olverembatinib (HQP1351) with BCL-2 Inhibitor Lisaftoclax (APG-2575) Overcomes Resistance in Gastrointestinal Stromal Tumors (GISTs)

  • Summary number: 1631

  • Track: Experimental and Molecular Therapeutics

  • Session title: Novel antitumor drugs 3

  • session time: Monday 17 April 2023, 9:00 a.m. – 12:30 p.m. EDT

Our results show that olverembatinib and the Bcl-2 inhibitor lisaftoclax have synergistic antitumor effects in imatinib-resistant GIST. Considering that resistance mechanisms are similar for most tyrosine kinase inhibitors (TKIs), this novel dual approach could have potential for treating patients with GIST whose disease has progressed after treatment with imatinib or other TKIs.

Alrizomadline (APG-115)
The MDM2 inhibitor alrizomadlin (APG-115) promotes the antitumor activity of mitogen-activated protein kinase (MAPK) inhibitors in uveal melanoma

  • Summary number: 1632

  • Track: Experimental and Molecular Therapeutics

  • Session title: Novel antitumor drugs 3

  • session time: Monday 17 April 2023, 9:00 a.m. – 12:30 p.m. EDT

Our results demonstrate the potential benefit of combining alirizomadlin with inhibitors of the MAPK pathway for the treatment of patients with uveal melanoma.
