In a phase 3 RUBY trial, dostarlimab combined with chemotherapy (carboplatin and paclitaxel) significantly increased progression-free survival as compared to placebo, with a substantial benefit in the dMMR–MSI-H population in patients with primary advanced stage III or IV or first recurrent endometrial Cancer. More severe...
In POSEIDON study, a treatment-naive patients with metastatic non-small cell lung cancer (NSCLC), tremelimumab (anti-CTLA-4 antibody) plus durvalumab (anti-PD-L1 antibody) and platinum-based chemotherapy demonstrated a statistically significant and clinically meaningful improvement in median Overall Survival (OS) [14 months vs 11.7 months] and median Progression Free...
In this Phase III study (CHOICE-01), patients with treatment-naive, advanced NSCLC with EGFR/ALK mutations, treatment with toripalimab (a humanized IgG4K monoclonal antibody specific for human PD-1) in combination with chemotherapy showed significantly better PFS (median PFS 13.1 v 5.5 months). This study supports the use...
In patients with advanced NSCLC without EGFR, ALK, or ROS1 genomic tumor aberrations, treatment with cemiplimab plus chemotherapy showed a consistent relationship between ORR and baseline PD-L1 expression, with benefits versus chemotherapy alone seen across all levels of baseline PD-L1 expression; there was also a...
In patients with pretreated germline BRCA1/2 breast cancer who had received a median of two prior chemotherapy lines for advanced disease, treatment with Lurbinectedin (a selective inhibitor of oncogenic transcription) showed an ORR of 28.6% (95% CI 11.3% to 52.2%), median DoR was 8.6 months,...
Indoleamine 2,3- dioxygenase 1 (IDO1) is a cytosolic heme-containing enzyme that functions to catalyze tryptophan (Trp) degradation and kynurenine (Kyn) production, and the Trp:Kyn ratio reflects IDO1 activity. Tobacco carcinogens upregulate IDO1. Clinically, smoker patients with non-small-cell lung cancer (NSCLC) exhibited high IDO1 levels and...
