Theseus Pharmaceuticals to Present Preclinical Data Characterizing Next-Generation Epidermal Growth Factor Receptor (EGFR) Inhibitors at the 2022 American Association for Cancer Research (AACR) Annual Meeting
Rhea-AI Summary
Theseus Pharmaceuticals (THRX) announced it will present a poster on next-generation EGFR inhibitors at the AACR 2022 Annual Meeting from April 8-13 in New Orleans. The poster will detail the characterization of selective EGFR inhibitors that target T790M and C797S mutations, which are prevalent in patients resistant to current therapies. These innovations may significantly impact non-small cell lung cancer treatment, as EGFR mutations occur in 10-50% of cases. The presentation will be made by Dr. Wei-Sheng Huang on April 12.
Positive
- Presentation of selective next-generation EGFR inhibitors addressing T790M and C797S mutations.
- Potential to improve treatment options for 10-50% of NSCLC patients with EGFR mutations.
Negative
- None.

CAMBRIDGE, Mass., March 8, 2022 /PRNewswire/ -- Theseus Pharmaceuticals, Inc. (NASDAQ: THRX) (Theseus or the Company), a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients through the discovery, development and commercialization of transformative targeted therapies, today announced that the Company will present a poster highlighting the characterization of potent and selective next-generation EGFR inhibitors at the American Association for Cancer Research (AACR) 2022 Annual Meeting, being held April 8-13, 2022 in New Orleans, Louisiana.
Presentation details:
Abstract Title: Discovery of potent and selective next-generation EGFR inhibitors with activity against single, double, and triple mutant EGFR variants including T790M and C797S
Abstract Number: 3342
Presenter: Wei-Sheng Huang, Ph.D., Vice President of Chemistry
Session Date and Time: Tuesday, April 12th, 1:30pm-5pm CT
The presentation will detail the characterization of compounds that potently inhibit the kinase activity, both in vitro and in vivo, of single, double, and triple mutant EGFR variants including T790M and C797S, with selectivity over wild-type EGFR and the ability to penetrate the central nervous system. These variants comprise all major classes of EGFR activating and resistance mutations that contribute to later-line clonal heterogeneity in patients who have been failed by current approved therapies.
EGFR activating mutations are observed in 10-50 percent of non-small cell lung cancer (NSCLC) patients and are initially sensitive to first, second, and third generation EGFR inhibitors. However, on-target resistance is observed in a substantial percentage of patients, with T790M and C797S mutations observed most frequently.
About Theseus Pharmaceuticals, Inc.
Theseus is a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients through the discovery, development and commercialization of transformative targeted therapies. Theseus is working to outsmart cancer resistance by developing pan-variant tyrosine kinase inhibitors (TKIs) to target all known classes of cancer-causing and resistance mutations that lead to variants in a particular protein in a given type of cancer. Theseus' lead product candidate, THE-630, is a pan-variant KIT inhibitor for the treatment of patients with advanced gastrointestinal stromal tumors (GIST), whose cancer has developed resistance to earlier lines of kinase inhibitor therapy. Theseus is also developing a fourth-generation, selective epidermal growth factor receptor (EGFR) inhibitor for C797S-mediated resistance to first- or later-line osimertinib treatment in patients with non-small cell lung cancer (NSCLC).
