E.2.1 | Main objective of the trial |
To evaluate the safety and tolerability of INCB050465 in participants with pemphigus vulgaris. |
|
E.2.2 | Secondary objectives of the trial |
To determine the systemic exposure to INCB050465. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1.Men and women aged 18 to 80 years at the time of consent.
2.Clinically documented and confirmed diagnosis of pemphigus vulgaris: a)Minimum of 6 months of pemphigus vulgaris diagnosis b)Positive for anti-DSG1 or DSG-3 c)PDAI score of 8 to 45 points d)Have active skin, scalp, or mucosal lesions
3.Participants who have disease progression after treatment with standard therapies that are known to confer clinical benefit, or who are intolerant to treatment. There is no limit to the number of prior treatment regimens.
4.Willingness to avoid pregnancy or fathering children based on the criteria below. a)Men must agree to take appropriate precautions to avoid fathering children (with at least 99% certainty) from screening through 90 days after the last dose of study drug and must refrain from donating sperm during this period. Permitted methods that are at least 99% effective in preventing pregnancy (see Appendix A) should be communicated to the participants and their understanding confirmed. b)Women of childbearing potential must have a negative serum pregnancy test at screening and before the first dose on Day 1 and must agree to take appropriate precautions to avoid pregnancy (with at least 99% certainty) from screening through safety follow-up. Permitted methods that are at least 99% effective in preventing pregnancy should be communicated to the participants and their understanding confirmed. c)Women of nonchildbearing potential (ie, surgically sterile with a hysterectomy and/or bilateral oophorectomy OR postmenopausal, defined as ≥ 12 months of amenorrhea before screening, confirmed by FSH levels at screening) are eligible.
5.If required, willing to receive PJP prophylaxis during the study period. |
|
E.4 | Principal exclusion criteria |
1.Pregnant or breast-feeding female.
2.Participants with pemphigus vulgaris who are treatment-naive.
3.Use of the following medications within the following periods before baseline: a) 2Weeks: i)Potent systemic CYP3A4 inhibitors and inducers or fluconazole. Note: Topical agents with limited systemic availability are permitted. Recommend to consult with medical monitors. ii)Topical treatment of pemphigus vulgaris lesions that may affect the disease assessment activities (eg, corticosteroids or tacrolimus/pimecrolimus). b)4 weeks: Systemic immunosuppressive (eg, cyclophosphamide and methotrexate), etanercept, anakinra, prednisone > 0.5 mg/kg per day (or oral corticosteroid equivalent dose). c)12 weeks or 5 half-lives (whichever is longer): infliximab, adalimumab, golimumab, abatacept, tocilizumab, certolizumab, secukinumab, IVIG, plasmapheresis, or any other biologic or experimental treatment. d)12 months: Anti-CD20 monoclonal antibody, for example, rituximab and ofatumumab.
4.Evidence or history of clinically significant infection or medical condition including the following: a)Any other active skin disease or condition (eg, bacterial, fungal, or viral infection) that may interfere with the course, severity, or assessments of pemphigus vulgaris. b)Chronic or ongoing infectious disease requiring long-term systemic treatment, including but not limited to chronic renal infection or chronic pulmonary infection with bronchiectasis. c)Active systemic viral infection or any active viral infection that, based on the investigator's clinical assessment, makes the participant an unsuitable candidate for the study. d)Positive test result for TB from the QuantiFERON®-TB Gold test or T-SPOT.TB test at screening (or, if 2 indeterminate tests, then as evaluated by a purified protein derivative test with a result of < 5 mm of induration within 3 months of screening). e)A history of active TB (treated or untreated) or history of untreated latent TB. f)Positive serology test results for HIV, HBsAg, HBV core antibody, or HCV (HCV antibody with positive HCV-RNA) at screening. g)Received live vaccine within 4 weeks before baseline or planning to receive live vaccine during the course of the study or within 4 weeks after EOT. h)Prolonged QT interval corrected for heart rate using Fridericia's formula (QTcF), defined as > 470 milliseconds for male and > 480 milliseconds for females. i)History of malignancy within 5 years before baseline, other than a successfully treated nonmetastatic neoplasms (eg, cutaneous squamous cell carcinoma, basal cell carcinoma, localized carcinoma in situ of the cervix, or melanoma in situ) j)History of solid organ transplant. k)Any serious illness or medical, physical, or psychiatric condition(s) that, in the opinion of the investigator, would pose a significant risk to the participant or interfere with the interpretation of safety, efficacy, or pharmacodynamic data.
5)Participants with laboratory values at screening, defined in Table 6 in Protocol
6)Known or suspected allergy to INCB050465 or any component of the study drug.
7)Known history of clinically significant drug or alcohol abuse in the last year before baseline.
8)Inability or unlikeliness of the participant to comply with the dose schedule and study evaluations, in the opinion of the investigator.
9)Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data.
10)Inability of the participant to comprehend or unwilling to sign the ICF.
