Testing hymecromone in adults with interstitial lung disease

Phase IIa Investigation of H01 in Adults With Interstitial Lung Disease (The SOLIS Study)

Phase 2 Interventional National Institutes of Health Clinical Center (CC) · NCT06325696

This study is testing a new medication called hymecromone to see if it can help adults with progressive interstitial lung disease feel better and improve their lung function.

What this trial studies

This Phase 2a open-label study aims to evaluate the safety, tolerability, and efficacy of hymecromone in adults diagnosed with progressive interstitial lung disease. Up to 37 participants will undergo a series of assessments over five months, including blood tests, lung function tests, and sputum samples. The primary objective is to measure the reduction of hyaluronan levels in participants, while secondary objectives include assessing clinical and functional changes, safety, and pharmacokinetics of the drug.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 years old diagnosed with idiopathic pulmonary fibrosis or other forms of progressive interstitial lung disease.

Not a fit: Patients with severe lung impairment or those who do not meet the specific inclusion criteria may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that may slow the progression of interstitial lung disease and improve patients' quality of life.

How similar studies have performed: While this approach is novel, similar studies targeting hyaluronan levels in lung diseases have shown promise, indicating potential for success.

* MD diagnosis of Idiopathic Pulmonary Fibrosis or other progressive ILD as defined previously
* DLCO\>30% and FVC\>45%
* Subjects in reproductive age who are heterosexually active must use an acceptable method of contraception: condoms (male or female) with or without a spermicidal agent, diaphragm or cervical cap with spermicide, IUD, or Hormone-based contraceptive
* Agreement to adhere to Lifestyle Considerations throughout study duration

EXCLUSION CRITERIA:

An individual who meets any of the following criteria will be excluded from participation in this study:

* Active on lung transplantation list
* On supplemental oxygen at rest
* Evidence of an acute respiratory infection or exacerbation of pulmonary fibrosis
* Known diagnosis of celiac disease or wheat or gluten allergies
* Cirrhosis or active viral or non-viral hepatitis: Bilirubin, AST and ALT values higher than twice the upper range of normal, or a Child-Pugh score of 7 or more
* Subjects with history of active Inflammatory Bowel Disease, dysphagia, achalasia, or difficulty swallowing capsules, tablets or pills
* Subjects with significant renal impairment defined as eGFR lower than 40 ml/min.
* Subjects with a baseline corrected Fridericia's QT interval (QTcF) \>450ms or baseline ECG abnormalities which, in the opinion of the study physician, are clinically significant and would place the participant at increased risk for adverse effects.
* Subjects with ongoing alcohol or illegal drug use disorder
* Subjects who are pregnant, lactating or attempting to conceive

  * Participants able to become pregnant (have not completed menopause, had a hysterectomy and/or both tubes and/or both ovaries removed) must use effective birth control methods to try and not become pregnant while participant in this study. Methods include (a) partner vasectomy, (b) bilateral tubal ligation, (c) intrauterine devices (IUDs), (d) hormonal implants (such as Implanon), or (e) other hormonal methods (birth control pills, injections, patches, vaginal rings).
  * Male participants able to father children with a partner able to become pregnant must agree to use effective birth control (listed above) to participate in this study.
* Known allergy to hymecromone or any component thereof
* Chronic therapy with medications that are known potent human UDP-glucuronosyltransferase inhibitors: canagliflozin, temazepam, tacrolimus.
* Physician concern that participant may not adhere to the study protocol
* Current participation in another clinical treatment trial for ILD. May participate after 12 weeks from conclusion of another treatment trial.
* Changing dose of other ILD medications over the 3 months prior to baseline
* Any condition(s) or diagnosis, both physical or psychological, or physical exam finding that place the participant at increased risk for adverse effects, as determined by the study physician.
