Description

Summary

This randomized, placebo-controlled phase 2 study is seeking to evaluate the efficacy and safety of belumosudil (KD025) for the treatment of diffuse cutaneous systematic sclerosis. Upon eligibility confirmation, a total of 60 adult subjects will be enrolled and randomized into 3 groups (1:1:1) to either receive orally administered belumosudil (200 mg once daily and 200 mg twice daily) or matched placebo for 28 weeks. The study will be double-blinded for the first 28 weeks followed by an open-label extension period of 24 weeks. After unblinding, the subjects on belumosudil will continue on the same belumosudil dose whereas the subjects in the placebo group will be re-randomized to one of the belumosudil doses.

Official Title

A Phase 2, Randomized, Placebo-controlled, Double-blind, Open-label Extension Multicenter Study to Evaluate the Efficacy and Safety of Belumosudil (KD025) in Subjects With Diffuse Cutaneous Systemic Sclerosis

Details

Systemic sclerosis (SSc) is a chronic autoimmune disease that causes widespread microvascular damage and excessive deposition of collagen in the skin and internal organs. Limited cutaneous systemic sclerosis is primarily cutaneous, affecting the hands, arms, and face. Diffuse cutaneous systemic sclerosis (dcSSc) is a more serious manifestation of the disease and is often rapidly progressive, not only involving the skin, but also involving internal organs including kidney, heart, and lungs. Subjects who have signed an Institutional Review Board/Independent Ethics Committee-approved informed consent form and met all of the inclusion/exclusion criteria will be enrolled. A total of 60 subjects will be randomized into 3 groups (1:1:1) to receive orally administered belumosudil 200 mg once daily (QD; n = 20 subjects), belumosudil 200 mg twice daily (BID; n = 20 subjects), or matched placebo (n = 20 subjects) for 28 weeks. The study will be double-blinded for the first 28 weeks followed by an open-label extension of 24 weeks. After unblinding, the subjects in Group 1 and 2 will continue on the same belumosudil dose whereas the subjects in the placebo group will be re-randomized to either belumosudil 200 mg QD or belumosudil 200 mg BID in 1:1 fashion.

Open to people ages 18-100

  1. Male and female subjects ≥ 18 years old with the diagnosis of dcSSc according to the 2013 American College of Rheumatology and European League Against Rheumatism criteria
  2. Must have disease duration (defined as interval from first non-Raynaud disease manifestation) of ≤ 5 years
  3. Must have mRSS of ≥ 15 but ≤ 35
  4. Active disease defined as any of the following within the 6 months prior to screening:
  5. Increase in mRSS by ≥ 3 units
  6. Increase in mRSS by ≥ 2 units with involvement of 1 new body area
  7. Involvement of 2 new body areas
  8. Symptoms indicative of skin activity such as severe cutaneous itching or burning
  9. Subjects receiving concomitant immunosuppression must be on a stable dose for at least 6 months prior to screening
  10. Adequate organ and bone marrow functions evaluated during the 28 days prior to enrollment as follows:
  11. Absolute neutrophil count ≥ 1.5 × 109/L

  12. Platelet count ≥ 100 × 109/L

  13. Total bilirubin ≤ 1.0 × upper limit of normal (ULN);
  14. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) within normal limits; and
  15. Serum creatinine ≤ 1.5 × ULN.
  16. Female subjects of childbearing potential have a negative pregnancy test at screening. Females of childbearing potential are defined as sexually mature women without prior hysterectomy or who have had any evidence of menses in the past 12 months. However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, anti-estrogens, or ovarian suppression.
  17. Women of childbearing potential (i.e., menstruating women) must have a negative urine pregnancy test (positive urine tests are to be confirmed by serum test) documented within the 24-hour period prior to the first dose of study drug.
  18. Sexually active women of childbearing potential enrolled in the study must agree to use 2 forms of accepted methods of contraception during the course of the study and for 3 months after their last dose of study drug. Effective birth control includes (1) intrauterine device plus 1 barrier method; (2) on stable doses of hormonal contraception for at least 3 months (e.g., oral, injectable, implant, transdermal) plus 1 barrier method; or (3) two barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm), or a vasectomized partner
  19. For male patients who are sexually active and who are partners of premenopausal women, agreement to use 2 forms of contraception as in Criterion Number 7 above during the treatment period and for at least 3 months after the last dose of study drug
  20. Male subjects must not donate sperm for 3 months after last dose of study drug.
  21. . Able to provide written informed consent prior to the performance of any study-specific procedures.

You CAN'T join if...

  1. Subject has QTcF > 450 ms
  2. Female subject who is pregnant or breastfeeding
  3. Participated in another study with an investigational drug within 28 days of study entry (for studies involving biologics within 3 half-lives of the biologic)
  4. History or other evidence of severe illness or any other conditions that would make the subject, in the opinion of the Investigator, unsuitable for the study
  5. Chronic heart failure with New York Heart Association Class II, III, or IV
  6. Positive human immunodeficiency virus (HIV) test
  7. Active hepatitis C virus (HCV), hepatitis B virus (HBV), or positive whole blood tuberculin test
  8. Diagnosed with any malignancy within 3 years of enrollment, with the exception of basal cell or completely resected squamous cell carcinoma of the skin, resected in situ cervical malignancy, resected breast ductal carcinoma in situ, or low-risk prostate cancer after curative resection
  9. Has had previous exposure to belumosudil or known allergy/sensitivity to belumosudil, or any other ROCK2 inhibitor
  10. . Scleroderma renal crisis within 4 months prior to enrollment
  11. . FVC ≤ 50% Predicted.
