Gastroesophageal Junction Cancer clinical trials at UCLA

A Phase Ib/II, open label, multi-center, randomized study designed to assess the safety, tolerability, pharmacokinetics and preliminary anti-tumor activity of immunotherapy-based treatment combinations in patients with locally advanced unresectable or metastatic G/GEJ cancer (hereafter referred to as gastric cancer) and esophageal cancer. Two cohorts of patients with gastric cancer have been enrolled in parallel in this study: the second-line (2L) Gastric Cancer Cohort consists of patients with gastric cancer who have progressed after receiving a platinum-containing or fluoropyrimide-containing chemotherapy regimen in the first-line setting, and the first-line (1L) Gastric Cancer Cohort consists of patients with gastric cancer who have not received prior chemotherapy in this setting. In each cohort, eligible patients will be assigned to one of several treatment arms. Additionally, a cohort of patients with esophageal cancer who have not received prior systemic treatment for their disease will be enrolled in this study. Eligible patients will be randomized to chemotherapy or the combination of chemotherapy with checkpoint inhibitor immunotherapy.

A Phase I-II, First-in-Human Study of SKB264 in Patients with Locally Advanced Unresectable/Metastatic Solid Tumors who are refractory to Available Standard Therapies. Patient must have historically documented, incurable, locally advanced or metastatic cancer that are refractory to standard therapies of one of the following types: 1. Triple negative breast cancer 2. Epithelial ovarian cancer 3. Non-small cell lung cancer 4. Gastric adenocarcinoma/Gastroesophageal junction adenocarcinoma 5. Small cell lung cancer 6. HR+/ HER2-breast cancer 7. Head and neck squamous cell carcinoma 8. Endometrial carcinoma 9. Urothelial carcinoma

A Phase 2, Multicenter, Open-Label Study of DKN-01 in Combination with Tislelizumab ± Chemotherapy as First-Line or Second-Line Therapy in Adult Patients with Inoperable, Locally Advanced or Metastatic Gastric or Gastroesophageal Junction Adenocarcinoma

This is a Phase 1/1b, multicenter, open-label, dose-escalation, and dose-expansion study to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and clinical activity of AB308 in combination with zimberelimab (AB122) in participants with advanced malignancies.

This is a Global Study of Neoadjuvant-Adjuvant Durvalumab or Placebo and FLOT Chemotherapy Followed by Adjuvant Durvalumab or Placebo in Patients with Resectable Gastric and Gastroesophageal Cancer (GC/GEJC) (MATTERHORN).

The main objective of this study is to compare efficacy of bemarituzumab combined with oxaliplatin, leucovorin, and 5-fluorouracil (5-FU) (mFOLFOX6) to placebo plus mFOLFOX6 as assessed by overall survival (OS) in participants with FGFR2b ≥10% 2+/3+ tumor cell staining (FGFR2b ≥10% 2+/3+TC)

This is a Phase 2/3, randomized, open-label study for the treatment of patients with HER2-positive Gastric cancer (GC) or Gastroesophageal Junction (GEJ) cancer conducted in two parts. Part A is a single-arm cohort (Cohort A, 40 to 110 patients) will evaluate safety and efficacy of margetuximab plus retifanlimab. Part B Part 1 has 4 arms (50 patients/arm). Patients will be randomized to margetuximab plus retifanlimab plus chemotherapy, margetuximab plus tebotelimab, plus chemotherapy, margetuximab plus chemotherapy, or trastuzumab plus chemotherapy.

The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in combination with chemotherapy (Cisplatin combined with 5-Fluorouracil [FP regimen] or oxaliplatin combined with capecitabine [CAPOX regimen]) versus placebo in combination with chemotherapy (FP or CAPOX regimens) in the treatment of human epidermal growth factor receptor 2 (HER2) negative advanced gastric or GEJ adenocarcinoma in adult participants. The primary hypotheses of this study are that pembrolizumab plus chemotherapy is superior to placebo plus chemotherapy in terms of overall survival (OS).

The study will compare the efficacy and safety of pembrolizumab plus trastuzumab in combination with standard of care (SOC) chemotherapy versus trastuzumab in combination with SOC chemotherapy in participants with HER2-positive gastric cancer. The primary hypotheses of the study are that pembrolizumab plus trastuzumab in combination with chemotherapy is superior to trastuzumab plus chemotherapy in terms of 1) progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR), and 2) overall survival (OS).
