About this trial
VG712 (A-dmDT390-bisFv(UCHT1) fusion protein) is a recombinant anti-CD3 immunotoxin that selectively depletes CD3-positive T cells through irreversible inhibition of protein synthesis. This Phase II study (CurbMF-001) evaluates the safety and efficacy of VG712 compared with mogamulizumab in subjects with relapsed or refractory mycosis fungoides (MF) who have failed 2 or more prior systemic therapies. The study has two parts: a lead-in dosing part (BOIN design, up to 24 subjects) to determine RP2D, followed by a randomized part (approximately 322 subjects, 1:1 VG712 vs. mogamulizumab). Sponsor: Virogen Biotechnology Inc.
Eligibility criteria
Qualifiers
Male and/or female, aged 18 years or older at the time of enrollment
Stage IB-IVB histologically confirmed relapsed or refractory mycosis fungoides (MF) without Sézary syndrome, with failure of 2 or more prior systemic therapies (for progression or toxicity as assessed by the investigator). Note: Total skin electron beam therapy, narrow band UVB, and psoralen plus UV light therapy are not counted as systemic therapies
ECOG performance status of 2 or less
Normal lung function evaluated by pulse oximetry after 5 minutes of rest in a seated position, with oxygen saturation values between 92% and 100% without supplemental oxygen
Disqualifiers
Current evidence of large cell transformation (LCT) in the randomized part (subjects with clinical features suggestive of LCT must have a biopsy performed within 4 months prior to Cycle 1 Day 1 without evidence of LCT; this exclusion criterion does not apply to the lead-in dosing part)
Inability to understand and give written informed consent for participation in this trial, including all evaluations and procedures specified by this protocol
Allergy to diphtheria toxin, a component of A-dmDT390-bisFv(UCHT1) fusion protein
Unstable or severe uncontrolled medical condition (e.g., uncontrolled diabetes, uncontrolled infections requiring systemic antibiotics, psychiatric illness/social situations, or any important medical illness or abnormal laboratory finding that would, in the investigator's judgment, increase risk to the subject)
