Arm Intervention/treatment
Experimental: INCB050465 Drug: INCB050465
INCB050465 administered orally once daily at the cohort-specified dose level.




Primary Outcome Measures :
  1. Number of treatment-emergent adverse events [ Time Frame: Up to 20 weeks ]
    Any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.


Secondary Outcome Measures :
  1. Cmax of INCB050465 [ Time Frame: Up to 6 weeks ]
    Maximum observed concentration.

  2. tmax of INCB050465 [ Time Frame: Up to 6 weeks ]
    Time to maximum concentration.

  3. Cmin of INCB050465 [ Time Frame: Up to 6 weeks ]
    Minimum observed concentration over the dose interval.

  4. AUC0-t of INCB050465 [ Time Frame: Up to 6 weeks ]
    Area under the concentration-time curve from time = 0 to the last measurable concentration at time = t.

  5. CL/F of INCB050465 [ Time Frame: Up to 6 weeks ]
    Apparent oral dose clearance.

Criteria

Inclusion Criteria:

  • Clinically documented and confirmed diagnosis of pemphigus vulgaris: minimum of 6 months of pemphigus vulgaris diagnosis; positive for anti-desmoglein (DSG)1 or DSG3; Pemphigus Disease Area Index score of 8 to 45 points; active skin, scalp, or mucosal lesions.
  • Disease progression after treatment with standard therapies that are known to confer clinical benefit, or intolerant to treatment; there is no limit to the number of prior treatment regimens.
  • Willingness to avoid pregnancy or fathering children.
  • If required, willing to receive Pneumocystis jirovecii pneumonia prophylaxis during the study period.

Exclusion Criteria:

  • Pregnant or breast-feeding female.
  • Participants with pemphigus vulgaris who are treatment-naive.
  • Use of protocol-specified medications within defined periods before baseline.
  • Evidence or history of clinically significant infection or protocol-defined medical conditions
  • Laboratory values outside the protocol-defined range at screening.
  • Known or suspected allergy to INCB050465 or any component of the study drug.
  • Known history of clinically significant drug or alcohol abuse in the last year before baseline.
  • Inability or unlikeliness of the participant to comply with the dose schedule and study evaluations, in the opinion of the investigator.
  • 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.
