Official title

PRISM: An Open-label, Multi-Center Extension Study to Investigate the Efficacy and Safety of Cobomarsen (MRG-106) Following Systemic Treatment in Subjects With Cutaneous T-Cell Lymphoma (CTCL), Mycosis Fungoides (MF) Subtype, Who Have Completed the SOLAR Study

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
