Nuvectis Pharma's NXP900 is emerging as a promising candidate in the fight against Non-Small Cell Lung Cancer (NSCLC), particularly for patients resistant to EGFR and ALK targeted therapies. Like Summit Therapeutics' Ivonescimab, which recently outperformed Merck's Keytruda in a Phase 3 trial, NXP900 targets treatment resistance but through a different mechanism.
NXP900 inhibits SRC/YES1 kinases, key drivers of cancer survival. Preclinical studies show its potential to reverse resistance to existing therapies and enhance their effectiveness when used in combination. While still in early clinical development, NXP900's targeted approach and potential applications beyond NSCLC make it a noteworthy contender in the evolving landscape of cancer treatment.
Merck's KEYTRUDA (pembrolizumab) plus chemotherapy has shown significant promise in treating high-risk early-stage triple-negative breast cancer (TNBC). In the Phase 3 KEYNOTE-522 trial, this regimen reduced the risk of death by 34% compared to chemotherapy alone. After a median follow-up of 75.1 months, the five-year overall survival rate was 86.6% for the KEYTRUDA regimen versus 81.7% for the chemotherapy-placebo regimen.
Key points:
- First immunotherapy-based regimen to show significant improvement in overall survival for high-risk early-stage TNBC
- Consistent benefit across subgroups, including PD-L1 expression, tumor size, and nodal status
- Safety profile consistent with previous studies
- KEYTRUDA is approved in the U.S. for this indication based on earlier trial results
Merck's KEYTRUDA demonstrates sustained overall survival benefit in advanced melanoma patients after 10 years. Key findings from the KEYNOTE-006 trial include:
- 34.0% of KEYTRUDA-treated patients were alive at 10 years vs. 23.6% for ipilimumab
- KEYTRUDA reduced death risk by 29% (HR=0.71)
- Median overall survival: 32.7 months for KEYTRUDA vs. 15.9 months for ipilimumab
- Median modified progression-free survival: 9.4 months for KEYTRUDA vs. 3.8 months for ipilimumab
These results highlight KEYTRUDA's long-term efficacy in advanced melanoma treatment, showcasing its potential to improve patient outcomes significantly.
Merck (NYSE: MRK) and Eisai announced positive results from the Phase 3 LEAP-012 trial evaluating KEYTRUDA® (pembrolizumab) plus LENVIMA® (lenvatinib) in combination with transarterial chemoembolization (TACE) for treating unresectable, non-metastatic hepatocellular carcinoma (HCC). The study showed:
1. 34% reduction in the risk of disease progression or death compared to TACE alone
2. Median progression-free survival (PFS) of 14.6 months vs 10.0 months for TACE alone
