ctDNA-Guided Adjuvant Therapy in Stage III Colon Cancer: DYNAMIC-III Validates Prognosis but Questions Intensification

ctDNA-Guided Adjuvant Therapy in Stage III Colon Cancer: DYNAMIC-III Validates Prognosis but Questions Intensification

The randomized phase 2/3 DYNAMIC-III trial shows that postoperative circulating tumor DNA (ctDNA) strongly stratifies recurrence risk in stage III colon cancer. ctDNA-guided de-escalation reduced oxaliplatin exposure and hospitalizations with outcomes close to standard care; escalation for ctDNA-positive disease did not improve recurrence-free survival.
Dual TIGIT/PD‑1 Blockade with Domvanalimab + Zimberelimab Plus FOLFOX Shows Promising Activity in First‑Line Advanced Gastric and GEJ Adenocarcinoma

Dual TIGIT/PD‑1 Blockade with Domvanalimab + Zimberelimab Plus FOLFOX Shows Promising Activity in First‑Line Advanced Gastric and GEJ Adenocarcinoma

A phase 2 arm of the EDGE‑Gastric trial reports a 59% confirmed objective response rate and median PFS 12.9 months with domvanalimab (anti‑TIGIT) plus zimberelimab (anti‑PD‑1) combined with FOLFOX in untreated HER2‑negative advanced gastric/GEJ/esophageal adenocarcinoma, with a manageable safety profile.

ctDNA-Guided Adjuvant Therapy in Stage III Colon Cancer: Prognostic Validation but No Benefit from Chemotherapy Intensification — Key Findings from the DYNAMIC-III Randomized Phase 2/3 Trial

The DYNAMIC-III trial validates circulating tumor DNA (ctDNA) as a strong prognostic marker in stage III colon cancer. ctDNA-guided de-escalation reduced oxaliplatin exposure and hospitalizations with near-standard outcomes, but escalation for ctDNA-positive patients failed to improve recurrence-free survival.

Dual TIGIT and PD‑1 Blockade with Domvanalimab + Zimberelimab plus FOLFOX Shows Promising Activity in First‑Line Advanced HER2‑Negative Gastroesophageal Adenocarcinoma

In a phase 2 cohort (EDGE‑Gastric A1), domvanalimab (anti‑TIGIT) plus zimberelimab (anti‑PD‑1) combined with FOLFOX produced a 59% ORR, median PFS 12.9 months and median OS 26.7 months in 41 previously untreated HER2‑negative gastroesophageal adenocarcinoma patients, with immune‑related AEs in 27%.
Perioperative Pembrolizumab + Trastuzumab with FLOT Achieves High pCR and Feasible Safety in HER2‑Positive Localized Esophagogastric Adenocarcinoma: Interim PHERFLOT Results

Perioperative Pembrolizumab + Trastuzumab with FLOT Achieves High pCR and Feasible Safety in HER2‑Positive Localized Esophagogastric Adenocarcinoma: Interim PHERFLOT Results

Interim results from the phase 2 PHERFLOT trial show a 48.4% pathological complete response and a 67.7% major pathologic response after four cycles of pembrolizumab, trastuzumab and FLOT in localized HER2‑positive esophagogastric adenocarcinoma; safety was consistent with known profiles.
MAGNITUDE final analyses: Niraparib + Abiraterone improves symptoms and delays chemotherapy but not overall survival in HRR‑altered mCRPC

MAGNITUDE final analyses: Niraparib + Abiraterone improves symptoms and delays chemotherapy but not overall survival in HRR‑altered mCRPC

Final MAGNITUDE results show niraparib combined with abiraterone–prednisone improves radiographic PFS, time to symptomatic progression and delays cytotoxic chemotherapy in HRR‑altered mCRPC (notably BRCA1/2), preserves patient‑reported quality of life, but did not demonstrate a statistically significant overall survival benefit in the primary analysis.
Neoadjuvant Nivolumab With or Without Low‑Dose Ipilimumab Produces High Pathologic Response and Organ Preservation in Resectable Cutaneous Squamous Cell Carcinoma: Results from the MATISSE Phase 2 Trial

Neoadjuvant Nivolumab With or Without Low‑Dose Ipilimumab Produces High Pathologic Response and Organ Preservation in Resectable Cutaneous Squamous Cell Carcinoma: Results from the MATISSE Phase 2 Trial

The randomized MATISSE trial shows neoadjuvant nivolumab ± low‑dose ipilimumab yields high major/partial pathological response rates, excellent 2‑year disease‑specific survival, and enables organ preservation in many patients with resectable cutaneous squamous cell carcinoma.
Neoadjuvant PD‑1/LAG‑3 Bispecific (tobemstomig) Matches Efficacy but Improves Safety Versus Nivolumab‑Ipilimumab in Resectable Stage III Melanoma: Insights from Morpheus‑Melanoma

Neoadjuvant PD‑1/LAG‑3 Bispecific (tobemstomig) Matches Efficacy but Improves Safety Versus Nivolumab‑Ipilimumab in Resectable Stage III Melanoma: Insights from Morpheus‑Melanoma

The randomized phase 1b/2 Morpheus‑Melanoma trial found that tobemstomig (anti‑PD‑1/anti‑LAG‑3 bispecific) produced comparable pathological response rates to nivolumab plus ipilimumab with a substantially improved safety profile in resectable stage III melanoma.
Prolonged Survival Transforms Leptomeningeal Metastasis in NSCLC: Contemporary Multicenter Cohort Shows TKIs and ICIs Improve Outcomes

Prolonged Survival Transforms Leptomeningeal Metastasis in NSCLC: Contemporary Multicenter Cohort Shows TKIs and ICIs Improve Outcomes

An international cohort of 2,052 NSCLC patients with leptomeningeal disease shows rising prevalence and improved survival in the modern treatment era. CNS‑penetrant tyrosine kinase inhibitors and immune checkpoint inhibitors are key drivers of delayed onset and longer leptomeningeal survival.
Immune Checkpoint Inhibitors Amplify Risk and Delay Onset of SJS/TEN: Evidence for a Two‑Hit Mechanism

Immune Checkpoint Inhibitors Amplify Risk and Delay Onset of SJS/TEN: Evidence for a Two‑Hit Mechanism

A large FAERS analysis links immune checkpoint inhibitors (ICIs) to markedly increased SJS/TEN risk, demonstrates additive synergy with high‑risk small molecules, and shows delayed latency particularly with anti–PD‑1 agents — supporting a two‑hit, T‑cell–mediated model and urging cautious coprescribing and prospective study.
Ezabenlimab plus mDCF Induction and Adaptive Chemoradiotherapy Achieve High Complete Response Rates in Stage 3 Squamous Cell Anal Carcinoma (INTERACT-ION)

Ezabenlimab plus mDCF Induction and Adaptive Chemoradiotherapy Achieve High Complete Response Rates in Stage 3 Squamous Cell Anal Carcinoma (INTERACT-ION)

The INTERACT-ION phase 2 trial reports that induction ezabenlimab with modified DCF followed by biomarker-guided, involved-node radiotherapy produced high clinical complete response rates (overall 77.8%) with a manageable safety profile in stage 3 anal squamous cell carcinoma.
