DSSG Group: Gastrointestinal

Previously untreated advanced/ metastatic HER-2 negative gastric/ gasto-esophageal junction (GEJ) cancer.

The purpose of this study is to assess the efficacy and safety of lenvatinib (E7080/MK-7902) plus pembrolizumab (MK-3475) plus chemotherapy compared with chemotherapy alone in participants with advanced/metastatic gastroesophageal cancer.

HER-2 positive metastatic and/or unresectable gastric or gasto-esophageal junction (GEJ) cancer

This study will evaluate the efficacy and safety of trastuzumab deruxtecan (T-DXd), a HER-2 targeting antinbody drug, compared with ramucirumab and paclitaxel (Ram + PTX) in participants with HER2-positive gastric or gastro-esophageal junction (GEJ) cancer who have progressed on or after a trastuzumab-containing regimen and have not received any additional systemic therapy.

Metastatic colorectal cancer (mCRC)

The main purpose of this study is to compare the clinical benefit, as measured by Progression-Free Survival (PFS), Objective Response Rate (ORR), and Overall Survival (OS), achieved by nivolumab in combination with ipilimumab or by nivolumab monotherapy in participants with Microsatellite Instability High (MSI-H) or Mismatch Repair Deficient (dMMR) metastatic colorectal cancer (mCRC).

Claudin 18.2 (CLDN18.2) Positive, Metastatic Pancreatic Adenocarcinoma

This study will asses the antitumor activity and safety of Zolbetuximab (IMAB362) in combination with Nab-Paclitaxel and Gemcitabine (Nab-P + GEM)

Bile duct cancer that is inoperable or has spread, in patients that test positive for FGFR2 gene fusion, or, FGFR2 gene mutations or amplifications.

To investigate the effects of the drug derazantinib (formerly ARQ 087) in patients who have a type of bile duct cancer that cannot be operated on, or has spread, called Advanced Intrahepatic Cholangiocarcinoma. Patients will have a positive genetic test for FGFR2 Gene Fusion or FGFR2 gene mutations or amplifications.

Advanced oesophago-gastric or colorectal cancer

The purpose of this trial is to determine the safety and efficacy of the drug lithium and the optimum dose when used with standard chemotherapy.

Hepatocellular Carcinoma

This study will evaluate the safety and efficacy of pembrolizumab (MK-3475) versus placebo as adjuvant therapy in participants with hepatocellular carcinoma (HCC) and complete radiological response after surgical resection or local ablation (KEYNOTE-937).
