A Study of VG712 in Patients With Mycosis Fungoides
United States386 participantsStarted 2026-07-30
Plain-language summary
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.

Inclusion criteria
. 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
. Adequate baseline organ function within 28 days before the start of study treatment, including: left ventricular ejection fraction (LVEF) of 50% or greater by MUGA scan or 2D echocardiogram without evidence of cardiac chamber hypertrophy, dilatation, or hypokinesis; no clinically significant abnormalities on a 12-lead ECG; bilirubin 1.5x ULN or less (except subjects with Gilbert's syndrome); AST and ALT each 2.5x ULN or less (or 5.0x ULN or less with known hepatic involvement by MF); calculated creatinine clearance greater than 50 mL/min using the Cockcroft-Gault formula; serum albumin 3.2 g/dL or greater (albumin infusions are not permitted to meet eligibility); platelets 75,000/uL or greater, ANC 1.0x10\^9/L or greater, Hgb greater than 8 g/dL (exception for subjects with low blood counts due to documented bone marrow involvement, with sponsor medical monitor approval required before enrollment)
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Progression-Free Survival (PFS)
Timeframe: From randomization until disease progression or death, assessed up to 72 months post-EOT visit.
. Has recovered from toxicities (except alopecia) of prior chemotherapy or radiation therapy to Grade 1 or less according to NCI-CTCAE v5.0
. Females and males must be willing to use an approved form of contraception while on study drug and for 3 months after the last dose of study drug
. Expected survival of 3 months or greater
Exclusion criteria
. 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)
. History of active malignancy within 2 years, or malignancies that may interfere with data interpretation, other than nonmelanoma skin cancer, melanoma in situ, carcinoma in situ of the uterine cervix/prostate/bladder/breast, localized prostate cancer with PSA less than 0.1 ng/mL, or thyroid cancer
. Clinical evidence of central nervous system MF involvement
. Known active, uncontrolled autoimmune disease requiring systemic corticosteroids, cytotoxic or biologic therapy. Exceptions permitted include: type I diabetes mellitus; hypothyroidism only requiring hormone replacement therapy; skin disorders such as vitiligo, psoriasis, or alopecia not requiring systemic therapy
. Baseline corrected QT interval greater than 470 ms; baseline QT interval corrected with Fridericia's method (QTcF) greater than 470 ms (average of triplicate ECG)
