Combination treatment of E7727 and decitabine for patients with solid tumors

A Phase I Dose-Escalation Study of E7727, an Oral Cytidine Deaminase Inhibitor (CDAi) With Oral Decitabine in Subjects With Solid Tumors

Phase 1 Interventional Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins · NCT03875287

This study is testing a new combination of two medications, E7727 and decitabine, to see if it can safely help people with advanced solid tumors who have already tried other treatments.

What this trial studies

This phase 1 study evaluates the safety and optimal dosing of E7727, an oral cytidine deaminase inhibitor, in combination with oral decitabine for patients with advanced solid tumors. The trial aims to enroll up to 35 patients, assessing both the hypomethylation effects and toxicity of the treatment. Participants must have previously received at least two lines of therapy and have measurable disease. The study will help determine the best dosage for future trials.

Who should consider this trial

Good fit: Ideal candidates are patients with advanced, unresectable, or metastatic solid tumors who have exhausted standard treatment options.

Not a fit: Patients who have recently undergone chemotherapy or radiotherapy, or those with active infections or certain gastrointestinal conditions, may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment alternatives.

How similar studies have performed: While this approach is novel, similar studies involving hypomethylating agents have shown promise in treating solid tumors.
