Brief Summary:

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, 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.

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 a separate clinical trial (MRG106-11-203 or PRISM), if they meet the entry criteria for that study.


Condition or disease Intervention/treatment Phase
Cutaneous T-Cell Lymphoma/Mycosis Fungoides Drug: Cobomarsen Drug: Vorinostat Phase 2

Detailed Description:

Study Design:

Subjects will be randomly assigned in a 1:1 ratio to receive either cobomarsen or vorinostat. A total of 126 subjects (63 per arm) will 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.

Primary Outcome Measures :
  1. Proportion of subjects achieving an objective response of at least 4 months duration (ORR4) [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Based on composite global response criteria including radiological imaging, flow cytometry, and the modified Severity Weighted Assessment Tool (mSWAT).


Secondary Outcome Measures :
  1. Progression-free survival [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Time from date of randomization until the date of earliest documented progression or death from any cause

  2. Pruritus Numerical Rating Scale [ Time Frame: Daily, up to 6 months, then weekly up to approximately 36 months (estimated study duration) ]
    Measures the patient's degree of itch related to mycosis fungoides based on an 11-point scale (from 0-10), with 0 being no itch and 10 being worst imaginable itch.

  3. Skindex-29 Dermatological Survey [ Time Frame: Monthly, up to approximately 36 months (estimated study duration) ]
    Measures the effects of skin disease on quality of life based on a 30-item questionnaire. The patient's responses are transformed to a linear scale from 0 to 100 and averaged to determine a subscore in three domains (Symptoms, Emotions and Functioning), as well as a total score. Lower scores indicate a lesser degree of skin disease interference with quality of life.

  4. Pain Numerical Rating Scale [ Time Frame: Daily, up to 6 months, then weekly up to approximately 36 months (estimated study duration) ]
    Measures the patient's intensity of pain related to mycosis fungoides based on an 11-point scale (from 0-10), with 0 being no pain and 10 being worst imaginable pain.

  5. Difference in drug tolerability by Patient Impression of Treatment Side Effects [ Time Frame: Weekly, up to approximately 36 months (estimated study duration) ]
  6. Duration of composite global response for responding subjects [ Time Frame: Up to approximately 36 months (estimated study duration) ]
  7. Complete response rate [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Based on composite global response criteria including radiological imaging, flow cytometry, and mSWAT.

  8. Skin disease severity based on modified Severity-weighted Assessment Tool (mSWAT) [ Time Frame: Monthly, up to approximately 36 months (estimated study duration) ]
    Measures skin disease severity based on the percentage of skin within each body region with patches, plaques, or tumors. Total scores are calculated by adding the total percent for each category of lesion (patch, plaque, or tumor) and multiplying by a weighting factor. Weighted subtotals are added together to obtain the total score. Lower scores indicate a lower degree of skin disease severity.

  9. Time to progression [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Time from date of randomization until the earliest date of confirmed progression.

  10. Overall survival [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Time from date of randomization until date of death from any cause.

  11. Number of participants with treatment-related adverse events as assessed by CTCAE v5.0 [ Time Frame: Up to approximately 36 months (estimated study duration) ]
  12. Plasma concentration of cobomarsen [ Time Frame: From Day 1 to End of Treatment visit, up to approximately 36 months (estimated study duration) ]
    Sparse pharmacokinetic samples will be collected for the purpose of population PK model development and analysis of covariate effects.


Other Outcome Measures:
  1. Number of participants with anti-drug antibody generation [ Time Frame: Up to approximately 36 months (estimated study duration) ]
  2. Change from baseline in Mycosis Fungoides/Sézary Syndrome Cutaneous T-cell Lymphoma-Quality of Life (MF/SS CTCL QOL) instrument [ Time Frame: Up to approximately 36 months (estimated study duration) ]
    Measures the impact of CTCL on patients' quality of life based on a 12-item questionnaire. The patient's total scaled score is determined from the sum of the 12 item scores and may range from 62 to 154. Lower scores indicate a lesser degree of CTCL disease interference with quality of life.
