A Study to Evaluate the Esophageal Stenosis Inhibition Effects of CLS2702C/CLS2702D After Endoscopic Submucosal Dissection (ESD) in Patients With Superficial Esophageal Cancer in the Steroid Administration Risk Group

Superficial Esophageal Cancer Clinical Trial

Official title:
A Phase III, Multicenter, Open-label Study to Evaluate the Esophageal Stenosis Inhibition Effects and Safety of CLS2702C/CLS2702D After Endoscopic Submucosal Dissection (ESD) in Patients With Superficial Esophageal Cancer in the Steroid Administration Risk Group

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy and safety of esophageal epithelial regenerative treatment by the transplantation of the product, CLS2702C, to the esophageal wound site after extensive ESD for superficial esophageal cancer in the steroid administration risk group.

Phase 3

Interventional studies are often prospective and are specifically tailored to evaluate direct impacts of treatment or preventive measures on disease.

Observational studies are often retrospective and are used to assess potential causation in exposure-outcome relationships and therefore influence preventive methods.

Expanded access is a means by which manufacturers make investigational new drugs available, under certain circumstances, to treat a patient(s) with a serious disease or condition who cannot participate in a controlled clinical trial.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
