Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main objective of this clinical trial is to study the efficacy and safety of cobomarsen (also known as MRG-106) for the treatment of cutaneous T-cell lymphoma (CTCL), mycosis fungoides (MF) subtype in subjects who have confirmed disease progression following treatment with vorinostat in the SOLAR clinical study (MRG106-11-201). Cobomarsen is designed to inhibit the activity of a molecule called miR-155 that may be important to the growth and survival of MF cancer cells.

The effects of treatment will be measured based on changes in skin lesion severity, disease-associated symptoms, and quality of life, as well as the length of time that the subject's disease remains stable or improved, without evidence of disease progression. The safety and tolerability of cobomarsen will be assessed based on the frequency and severity of observed side effects.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Study Design:

Up to 60 subjects are expected to be enrolled after discontinuation from the SOLAR clinical study (MRG106-11-201). Cobomarsen will be administered in the clinic by 2-hr intravenous infusion on Days 1, 3, 5 and 8, and weekly thereafter. Treatment will continue until the subject becomes intolerant, develops clinically significant side effects, progresses, or the trial is terminated.
