Investigators observe a benefit with durvalumab plus neoadjuvant chemotherapy among subgroups of patients regardless of microsatellite instability status in the phase 3 MATTERHORN trial.

Findings from the phase 3 FRESCO-2 trial support fruquintinib’s potential to provide an improved survival benefit and quality of life for those with previously treated metastatic colorectal cancer.

The DeFianCe trial is using DKN-01 plus bevacizumab and chemotherapy to determine if a clinical benefit would occur in patients with microsatellite stable colorectal adenocarcinoma.

Data from the phase 3 SKYSCRAPER-08 trial may support tiragolumab plus atezolizumab and chemotherapy as an alternative frontline treatment option for those with locally advanced or metastatic esophageal squamous cell carcinoma.

Neoadjuvant camrelizumab plus chemotherapy may hold promise as a standard of care in locally advanced esophageal squamous cell carcinoma, according to Yin Li, MD.

Combining ASKB589 with capecitabine, capecitabine, and sintilimab leads to no treatment discontinuation due to adverse effects among patients with gastric or gastroesophageal junction cancer in a phase 1/2 trial.

In the overall population and in patients with a PD-L1 CPS of 5 or greater who received nivolumab plus chemotherapy, overall survival and progression-free survival improved when compared with chemotherapy alone.

Results from an observational study found nivolumab plus chemotherapy helped enhance overall survival and progression-free survival for patients with advanced or metastatic gastric cancer, gastroesophageal junction cancer, or esophageal adenocarcinoma.

An overview of NRG1 fusion–positive tumors was given by experts in the gastrointestinal and lung cancer space in a recent Frontline Forum.

Sugemalimab is now approved for managing esophageal squamous cell carcinoma in China following results from the phase 3 GEMSTONE-304 study.

Investigators indicate that, although treatment with adjuvant/neoadjuvant pembrolizumab results in an absolute decrease in risk of an event, the benefit was not statistically significant in those with untreated, locally advanced gastric/GEJ cancer.

In Europe, pembrolizumab is now available as a treatment in combination with fluoropyrimidine-/platinum-containing chemotherapy for HER2-negative gastric or GEJ adenocarcinoma, as well as in combination with gemcitabine/cisplatin for locally advanced biliary tract carcinoma.

First-line pembrolizumab plus chemotherapy has been approved by the FDA for patients with HER2-negative gastric or gastroesophageal junction adenocarcinoma.

Approval of PD-L1 IHC 22C3 pharmDx may also identify patients with non–small cell lung cancer and other malignancies who may benefit from treatment with pembrolizumab.

Only patients with PD-L1–positive tumors may receive treatment with pembrolizumab plus trastuzumab and chemotherapy for HER2-positive gastric or gastroesophageal junction adenocarcinoma following the FDA’s amendment.

CHM 2101 will be assessed as part of a phase 1A/B clinical study in a population of patients diagnosed with advanced colorectal cancer, gastric cancer, and neuroendocrine cancer.

CMG901 demonstrated a well-tolerated safety profile in patients with CLDN18.2-positive, advanced gastric/gastroesophageal junction cancer.

Results from arm A1 of the phase 2 EDGE-Gastric study indicate that patients with gastric, gastroesophageal junction, and esophageal adenocarcinoma experienced improved responses after receiving domvanalimab/zimberelimab.

Results from the phase 3 KEYNOTE-966 trial led to the approval of pembrolizumab plus gemcitabine and cisplatin for patients with locally advanced unresectable or metastatic biliary tract cancer.

Pembrolizumab appears to improve overall survival vs placebo when added to trastuzumab and chemotherapy among patients with metastatic HER2-positive gastric or gastroesophageal junction cancer.

Adding durvalumab to standard-of-care chemotherapy appears to improve downstaging in patients with resectable gastric cancer and gastroesophageal junction cancer in the phase 3 MATTERHORN study.

Findings from the phase 3 TARGET-TP trial support a biomarker-driven primary thromboprophylaxis strategy in adult patients with lung and gastrointestinal cancers as routine care.

Rates of obesity appear to correlate with increasing incidence of cancer in young populations, according to Monique Gary, DO, MSc, FACS.

Data from the phase 2 SGNTUC-019 study support HER2 as an actionable biomarker in patients with metastatic biliary tract cancer.

Two phase 2 studies are assessing the efficacy of BDC-1001 in several disease states, including colorectal, gastroesophageal, endometrial, and breast cancer.
