REZILIENT: Researching Zipalertinib In EGFR Non-Small Cell Lung Cancer Tumors

About Zipalertinib
Zipalertinib (development code: CLN-081/TAS6417) is an orally available small molecule designed to target activating mutations in EGFR. The molecule was selected because of its ability to inhibit EGFR variants with exon 20 insertion mutations, while sparing wild-type EGFR. Zipalertinib is designed as a next generation, irreversible EGFR inhibitor for the treatment of a genetically defined subset of patients with non-small cell lung cancer. Zipalertinib has received Breakthrough Therapy Designation from the FDA.

Zipalertinib is being developed by Taiho Oncology, Inc., its parent company, Taiho Pharmaceutical Co., Ltd., and in collaboration with Cullinan Therapeutics, Inc. in the U.S.

About the EGFR exon 20 insertion mutations
NSCLC is a common form of lung cancer and up to 4% of all cases have EGFR exon 20 insertions, which makes them the third most common EGFR mutation subtype.2 In the United States, approximately 16% of patients with NSCLC harbor EGFR mutations, with insertions at exon 20 accounting for up to 12% of these mutations.

"The granting of this EU patent represents another milestone that provides expanded global protection along with building our intellectual capital and differentiation from any existing or emerging competitive technologies that may leverage the beneficial characteristics of binding to human serum albumin," commented Pankaj Mohan, Ph.D., Founder and CEO of Sonnet. "Further, this European patent issuance expands the global IP protection for our product pipeline beyond previous patents issued in China, Japan, Russia and New Zealand, which we believe provides further validation for our FHAB platform."

Sonnet’s FHAB platform consists of a single, fully human construct of a FHAB antibody fragment that has high affinity to bind to human albumin. The platform provides an off-the-shelf lock and load opportunity to rapidly develop numerous therapeutic biologics.

John Cini, Ph.D., Co-Founder and CSO of Sonnet commented, "The FHAB platform technology provides each of Sonnet’s pipeline drug candidates with either a mono- or bi-functional mechanism of action, thus allowing for the potential of biological synergy between cytokines. Preclinical comparative in vivo studies with wild type cytokines have shown that FHAB-derived drug candidates have reproducibly extended pharmacokinetics, enhanced payload delivery to the tumor and improved efficacy."

Prostate Cancer

TALZENNA plus XTANDI:Oral and poster presentations from the pivotal Phase 3 TALAPRO-2 trial of TALZENNA in combination with XTANDI will provide detailed results on the statistically significant and clinically meaningful improvement in OS in all-comers (cohort 1) as well as in those patients with homologous recombination repair (HRR) gene-mutated mCRPC (cohort 2), compared to XTANDI alone. TALZENNA in combination with XTANDI has been approved for use in over 35 countries globally for patients with certain types of mCRPC*. The OS results will be shared with global health authorities to potentially update the TALZENNA label.
XTANDI: Six abstracts continue to underscore the benefit of XTANDI across its approved indications, including two posters highlighting follow-up analysis from the EMBARK trial of XTANDI in combination with leuprolide in patients with non-metastatic castration-sensitive prostate cancer with biochemical recurrence at high-risk for metastasis.
Mevrometostat: The first randomized PFS results from the ongoing Phase 1 dose-expansion study examine the potential of mevrometostat (PF-06821497), an investigational selective inhibitor of enhancer of zeste homolog 2 (EZH2), in combination with XTANDI in patients with mCRPC, compared to XTANDI alone. Pfizer initiated two pivotal Phase 3 trials for mevrometostat plus XTANDI in 2024 and expects to start a Phase 3 study of mevrometostat plus XTANDI in first-line mCSPC during the first half of 2025.
Bladder Cancer

PADCEV: Long-term follow-up data from the groundbreaking Phase 3 EV-302 study of PADCEV in combination with pembrolizumab, including OS and safety data, continue to demonstrate consistent efficacy versus chemotherapy in a broad population, reinforcing the combination as standard of care in first-line treatment of la/muC.
Disitamab vedotin: Updated efficacy and safety data from an ongoing Phase 2 study (sponsored by Remegen) evaluating the HER2-targeting ADC disitamab vedotin plus toripalimab show encouraging results as a perioperative regimen in HER2-expressing muscle-invasive bladder cancer (MIBC). These data add to the growing body of evidence supporting the continued development of disitamab vedotin across stages of bladder cancer.
Sasanlimab: Three real-world evidence poster presentations highlight the need for advanced treatment options for patients with non-muscle invasive bladder cancer (NMIBC), including presentations on Bacillus Calmette-Guérin (BCG) treatment patterns, impact of BCG shortages, and outcomes and treatment patterns in patients with high-risk NMIBC. Pfizer recently reported positive topline results for sasanlimab in combination with BCG as induction therapy with or without maintenance in patients with BCG- naïve, high-risk NMIBC. Detailed results from the Phase 3 CREST trial will be presented at an upcoming congress.
