Pilot Trial of CRLX101 in Treatment of Patients With Advanced or Metastatic Stomach, Gastroesophageal, or Esophageal Cancer That Cannot be Removed by Surgery

Adenocarcinoma of the Gastroesophageal Junction Clinical Trial

Official title: Pilot Trial of CRLX101 in the Treatment of Patients With Advanced Gastric, Gastroesophageal, or Esophageal Squamous or Adenocarcinoma

Status Completed

Clinical Trial Summary

This pilot clinical trial studies cyclodextrin-based nanopharmaceutical CRLX101 in treating patients with advanced or metastatic stomach, gastroesophageal, or esophageal cancer that has progressed through at least one prior regimen of chemotherapy and cannot be removed by surgery. CRLX101 delivers the cytotoxic topoisomerase-1 inhibitor camptothecin into tumor cells and is hypothesized to interrupt the growth of tumor cells.

Clinical Trial Description

PRIMARY OBJECTIVES:

I. To evaluate pre- and post-treatment biopsies to assess CRLX101 (cyclodextrin-based polymer-camptothecin CRLX101) nanoparticle and 20(S)-Camptothecin (CPT) uptake in tumor and normal tissue.

SECONDARY OBJECTIVES:

I. To evaluate the safety and toxicity of CRLX101 in this patient population.

II. To examine the antitumor efficacy of CRLX101 in advanced gastric/gastroesophageal junction (GEJ)/esophageal squamous or adenocarcinoma including clinical benefit rate (complete response [CR] + partial response [PR] + stable disease [SD]) at 4 months and overall survival.

OUTLINE:

Patients receive cyclodextrin-based polymer-camptothecin CRLX101 intravenously (IV) over 60 minutes on days 1 and 15. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity.

Patients achieving stable disease or better, may receive treatment for an additional 6 months.

After completion of study treatment, patients are followed up monthly. ;
