Gastric Cancer

Pembrolizumab and fluoropyrimidine- and platinum-containing chemotherapy are now FDA-approved for the treatment of patients with locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma.

This companion diagnostic tool, which is already approved for use in 5 other cancer types, identifies patients who may be suited for treatment with pembrolizumab.

The updated indication limits the use of pembrolizumab and chemotherapy to tumors expressing PD-L1 as determined by an FDA-approved test.

Phase 2 studies are investigating BDC-1001 in HER2-positive gastroesophageal, colorectal, breast, and endometrial cancers.

According to interim phase 2 results, GEN-001 in combination with avelumab has a significant objective response rate in patients with gastric and gastroesophageal junction adenocarcinoma.

PT886, a novel bispecific antibody which targets claudin 18.2 and CD47, is currently being evaluated in a phase 1 study for patients with gastric, gastroesophageal junction and pancreatic adenocarcinomas.

A read out from the phase 3 KEYNOTE-859 at the February ESMO Virtual Plenary hints pembrolizumab/chemotherapy is a new treatment choice for locally advanced or metastatic, HER2-negative gastric or gastroesophageal junction adenocarcinoma.

The combination of zolbetuximab and mFOLFOX6 prolonged survival in patients with CLDN18.2+ advanced gastric gastroesophageal junction adenocarcinoma, according to the phase 3 data from the SPOTLIGHT trial.

Findings presented at the 2022 Gastrointestinal Cancers Symposium warrant the need for new treatments that attack HER2-low advanced gastric cancer.

During a Targeted Oncology case-based roundtable event, Syma Iqbal, MD, discussed the addition of nivolumab to chemotherapy for patients with gastric/gastroesophageal junction cancer based on PD-L1 status. This is the second of 2 articles based on this event.

During a Targeted Oncology case-based roundtable event, May Cho, MD, discussed with participants how their practice is impacted by the introduction of trastuzumab deruxtecan for HER2+ gastric cancer.

During a Targeted Oncology case-based roundtable event, Syma Iqbal, MD, discussed with participants their impressions of the CheckMate 649 chemoimmunotherapy regimen for patients with gastric/gastroesophageal junction cancers. This is the first of 2 articles based on this event.

Initial results from the phase 3 spotlight study show that the study met its primary and key secondary end point of progression-free and overall survival.

In a first-in-human trial, a peptide-drug conjugate showed tolerability and antitumor activity in patients with advanced solid tumors.

In an interview with Targeted Oncology, Ronan Kelly, MD, discussed the most recent updates seen in these patient populations and what research aims to further examine.

New results from the DESTINY-Gastric02 study include responses, survival data for patients receiving trastuzumab deruxtecan for with locally advanced or metastatic HER2-positive gastric or gastroesophageal junction adenocarcinoma.

ADP-A2M4CD8, an autologous T-cell therapy, showed promising antitumor activity in several solid tumor types including ovarian, gastric, and urothelial cancer.

Orphan drug designation has been granted by the FDA to XMT-2056 for the treatment of patients with gastric cancers.

CMG90 is the only drug in its class to have received fast-track status to date. Prior to its fast track status, the drug was granted orphan drug designation by the FDA.

During a debate at the Gastrointestinal Cancers Symposium, Florian Lordick, MD, argued that knowledge of PD-L1 expression level was needed before starting immune checkpoint inhibitor therapy. He was challenged by Aaron James Scott, MD, who argued that knowledge of PD-L1 is not necessary before initiating immune checkpoint inhibitor therapy.

John Marshall, MD, discusses the DESTINY-Gastric01 study of fam-trastuzumab deruxtecan-nxki in patients with locally advanced or metastatic HER2-positive gastric cancer.

TST001 has shown to be safe in ongoing trials alone or in combination with chemotherapy and displayed encouraging anti-tumor activity signals in gastric cancer and other solid tumor patients expressing CLDN18.2.

In an interview with Targeted Oncology following the tweet chat, Yelena Y. Janjigian, discussed the key takeaways from the discussion and highlighted the biomarkers and standard of care for the patient in this case.

Ryan Sugarman, MD, discusses the design and purpose of the CheckMate 649 trial for gastroesophageal cancers, gastric cancer, and esophageal adenocarcinoma.

In an interview with Targeted Oncology, Ryan Sugarman, MD, discussed the CheckMate 649 trial and Q-TWiST results to provide a further understanding of survival and quality of life benefit of nivolumab plus chemo versus chemo alone.

Findings show DKN-01, tislelizumab, and capecitabine/oxaliplatin (CAPOX) combination to be well tolerated and have encouraging clinical activity as frontline treatment of patients with advanced gastroesophageal adenocarcinoma.

In the CheckMate 649 trial, durable survival benefit was achieved with Nivolumab plus chemotherapy in patients with gastric or gastroesophageal junction cancer.

Results from the phase 3 KEYNOTE-062 study appear mixed for both pembrolizumab monotherapy versus chemotherapy and pembrolizumab plus chemotherapy versus chemotherapy alone in patients with advanced gastric or gastroesophageal junction adenocarcinoma.
