About this study

Official title: SOLAR: A Phase 2, Randomized, Open-label, Parallel-group, Active Comparator, Multi-center Study to Investigate the Efficacy and Safety of Cobomarsen (MRG-106) in Subjects With Cutaneous T-Cell Lymphoma (CTCL), Mycosis Fungoides (MF) Subtype

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. 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 study will compare the effects of cobomarsen to vorinostat, a drug that has been approved for the treatment of CTCL in the United States and several other countries.

Participants in the clinical trial will be randomly assigned to receive either weekly doses of cobomarsen by injection into a vein or daily oral doses of vorinostat. Participants will continue on their assigned treatment as long as there is no evidence of progression of their cancer. The effects of treatment will be measured based on changes in skin lesion severity, 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.

Participants assigned to receive vorinostat who experience progression of their disease during their participation in this study may have the option to be treated with cobomarsen in an open-label, crossover arm of the same study if they meet the entry criteria for that part of the study.

Read the detailed description

Study Design:

Subjects will be randomly assigned in a 1:1 ratio to receive either cobomarsen or vorinostat. Approximately 126 subjects (63 per arm) are expected to be enrolled. Cobomarsen will be administered in the clinic by 2-hr intravenous infusion on Days 1, 3, 5 and 8, and weekly thereafter. Vorinostat will be dispensed to study subjects and taken as a daily oral dose according to the manufacturer's labeled dosing instructions. Treatment will continue until the subject becomes intolerant, develops clinically significant side effects, progresses, or the trial is terminated. An interim analysis will be conducted after approximately 40 subjects have been followed for a minimum of approximately 6 months. Enrollment will be suspended until the completion of the interim analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Subjects Achieving an Objective Skin Response of at Least 4 Months Duration (ORR4)

    ORR4 is the percentage of subjects with a complete response (CR) or partial response (PR) in the skin for 4 consecutive months confirmed by repeat assessments no less than 28 days (± 3 days) later. The modified Severity Weighted Assessment Tool (mSWAT) is used to measure skin disease severity based on the percentage of body surface area (BSA) with patches, plaques, or tumors. Total scores are calculated by multiplying the BSA percentage for each category of lesion (patch, plaque, or tumor) by a weighting factor and adding the three sub-scores. Lower scores indicate a lower degree of skin disease severity. CR corresponds to 100% clearance of skin lesions present at baseline (mSWAT score of 0). PR corresponds to 50-99% clearance of skin disease present at baseline (at least 50% reduction in mSWAT score), without new tumors.

    Measured: Date of first dose through the earlier of last study visit or interim analysis data cut-off date of 12-Oct-2020, up to 16 months

Secondary outcomes (10)
  1. Progression-free Survival (PFS)

    Time from date of randomization until the date of earliest documented progression or death from any cause. The duration of PFS was censored at the date of the last mSWAT assessment if the subject was alive and had no documented progression. Disease progression in the skin is defined as ≥ 25% increase in mSWAT score from baseline or, in participants with complete or partial response, increase in mSWAT score of greater than the sum of the nadir plus 50% baseline score.

    Measured: Date of first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  2. Complete Response Rate

    Percentage of subjects with a complete response in the skin based on mSWAT

    Measured: Date of first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  3. Time to Progression

    Time from date of randomization until the earliest date of confirmed progression

    Measured: Date of first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  4. Time to Maximal Effect in mSWAT

    Time to greatest improvement in mSWAT score

    Measured: Monthly from first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  5. Objective Response Rate in the Skin of at Least 28-days Duration (ORR1)

    Percentage of participants achieving ≥ 50% improvement in mSWAT of at least 28-days duration

    Measured: Monthly from first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  6. Percentage of Subjects Achieving ≥ 50% Improvement in mSWAT at 28 Days

    Percentage of subjects achieving ≥ 50% improvement from baseline in mSWAT at 28 days after first dose

    Measured: 28 days after first dose

  7. Percentage of Subjects Achieving ≥ 50% Improvement in mSWAT at 4 Months

    Percentage of subjects achieving ≥ 50% improvement from baseline in mSWAT at 4 months after first dose

    Measured: 4 months after first dose

  8. Time to ≥ 50% Improvement in mSWAT

    Time from date of randomization until ≥ 50% improvement in mSWAT score

    Measured: Monthly from first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  9. Duration of Response in Skin

    Duration of response in skin (no progression after achieving ≥ 50% improvement in mSWAT)

    Measured: Monthly from first dose through interim analysis data cut-off date of 12-Oct-2020, up to 16 months

  10. Pruritus Medication Utilization

    Change from baseline in number of pruritus medications taken per subject

    Measured: Date of first dose through end of treatment or interim analysis data cut-off date of 12-Oct-2020, up to 16 months
