A Study to Evaluate experimental immuno-modulator in Subjects With Idiopathic Pulmonary Fibrosis
This study is being conducted to evaluate the safety, tolerability, and activity of 400 mg of KD025 once-daily (QD) compared to Best Supportive Care(BSC) in male and postmenopausal/surgically sterilized female subjects with IPF.
A Randomized, Phase 2, Open-Label, Multicenter Study to Evaluate the Safety, Tolerability, and Activity of KD025 in Subjects With Idiopathic Pulmonary Fibrosis (IPF)
Approximately 81 subjects with IPF will be randomly enrolled in a 2:1 ratio (KD025 to BSC) to one of two treatment groups. Subjects randomized to Treatment Group 1 will receive KD025 400 mg QD orally for 24 weeks, with the option for continuation as long as there is no safety signal and clinical progress continues. Subjects randomized to Treatment Group 2 will receive BSC (as deemed appropriate by the investigator). Subjects randomized to BSC will undergo the same procedures and assessments as subjects on KD025.

Open to people ages 18 years and up
- Adult male and postmenopausal/surgically sterilized female subjects at least 18 years of age (if female, is surgically sterilized [ie, total hysterectomy, or bilateral salpingo-oophorectomy]).
- Able to provide written informed consent before the performance of any study specific procedures.
- IPF diagnosis within 5 years before study entry, proven according to the American Thoracic Society/European Respiratory Society consensus conference criteria, with surgical lung biopsy. In the absence of a surgical lung biopsy, HRCT must be consistent with usual interstitial pneumonitis.
- Resting state SpO2 ≥ 88% with or without supplemental oxygen, FVC % ≥ 50% normal predicted value, and DLCO ≥ 30% normal predicted value at baseline.
- Men with partners of childbearing potential must be willing to use 2 medically acceptable methods of contraception during the trial and for 3 months after the last dose of study drug. Effective birth control includes (a) intrauterine device (IUD) plus 1 barrier method; (b) stable doses of hormonal contraception for at least 3 months (eg, oral, injectable, implant, transdermal) plus 1 barrier method; (c) 2 barrier methods. Effective barrier methods are male or female condoms, diaphragms, and spermicides (creams or gels that contain a chemical to kill sperm); or (d) vasectomy.
- Have adequate bone marrow function:
- ANC > 1500/mm3
- Hemoglobin > 9.0 g/L
- Platelets > 100,000/mm3
- Willing to complete all study measurements and assessments in compliance with the protocol
- Has either received pirfenidone and/or nintedanib or has been offered both treatments (with last dose administered at least 1 month before the expected start of study drug dosing). If either or both pirfenidone and nintedanib treatment has not been given, then documentation that the patient was offered both treatments must be documented.
