Brief Summary:
The purpose of this study is to determine whether KC706 is effective in the prevention and healing of blisters in patients with pemphigus vulgaris, while the patient remains on stable doses of corticosteroids and/or immunosuppressants.

Condition or disease Intervention/treatment Phase
Pemphigus Vulgaris Drug: KC706 Phase 2

Detailed Description:
The present study is designed to follow-up on pre-clinical observations that administration of KC706 is associated with prevention of the development of lesions in a mouse model of PV. Patients participating in this study will be those with active disease in spite of ongoing treatment with corticosteroids and/or immunosuppressive agents. The dose chosen for this clinical study is 300 mg once daily. The primary assessment of interest will be pemphigus lesion status during dosing with KC706.

Intervention Details:
  • Drug: KC706
    300 mg once daily (QD) for 12 weeks.

Primary Outcome Measures :
  1. To evaluate the ability of KC706 to prevent the appearance of new lesions and heal existing lesions, while maintaining stable doses of corticosteroids and/or immunosuppressants in patients with pemphigus vulgaris. [ Time Frame: 16 weeks ]

Secondary Outcome Measures :
  1. Evaluate the safety of KC706 in patients with PV and to assess plasma levels of KC706 with once daily dosing. [ Time Frame: 16 weeks ]

  • Patients should have active PV skin, scalp or mucosal lesions that meet at least one of the following criteria at the Baseline Visit:

    • > 3 new lesions/week every week in the previous 3 weeks (skin, scalp, and/or mucosal), with healing occurring at a rate to match the appearance of new lesions; or
    • At least 3 active, established lesions with a Pemphigus Lesion Score of at least 2; skin or scalp lesions must be ≥ 5mm in diameter to qualify; there is no size requirement for mucosal lesions; or,
    • 1 large active established skin, scalp, or mucosal lesion > 10 mm;
  • Accessibility to veins suitable for venipuncture;
  • Patients must be cooperative, able to read, understand and give informed consent, and able to adhere to the study visit schedule and protocol requirements; and,
  • Patients must be willing to follow adequate contraceptive measures during the study (both sexes).

Exclusion Criteria:

  • Infection with HIV;
  • Past or present diagnosis of hepatitis confirmed by serology or elevated hepatic enzymes;
  • History of alcoholic liver disease or cirrhosis;
  • Clinically significant concurrent medical disease or laboratory abnormalities evidenced by one or more of the following:

  • Uncontrolled diabetes (defined as diabetes requiring hospitalization or emergency care in the 3 months prior to first dose of study drug);
  • History or suspicion of Gilbert's syndrome;
  • Significant blood loss (> 500 mL) within 28 days prior to receipt of study drug;
  • Use of an investigational drug within 30 days of screening, or longer if that drug is expected to have long-acting effects (e.g., modulation of B-cell activity);
  • Use of Rituximab within the past 6 months;
  • Use of intravenous IgG within the past 3 months,
  • Current or recent history (within 12 months of screening) of drug or substance abuse, including alcohol;
  • Known or suspected pregnancy; nursing mothers;
  • Clinically significant abnormality on the screening physical examination performed at the Baseline Visit, laboratory testing, vital signs or electrocardiogram suggestive of significant unstable medical condition other than the disease under study;
  • Condition which, in the opinion of the Investigator, could interfere with participation in the study or would put the patient at unacceptable risk;
