This study explores a potential new treatment for adults with moderate-to-severe asthma using a drug called linvemastat, which targets an enzyme linked to lung inflammation. Despite using standard asthma medications, many patients still struggle with symptoms, so researchers are testing whether linvemastat can improve lung function and reduce flare-ups. In a carefully controlled trial, participants receive either one of two doses of the drug or a placebo, while continuing their usual treatments. Over 16 weeks, scientists monitor breathing capacity, symptom control, and safety to determine if linvemastat could offer a meaningful new option for asthma management.

This clinical study investigates the potential of a new drug, linvemastat, to improve outcomes for adults with moderate-to-severe asthma who continue to experience symptoms despite using standard treatments like inhaled corticosteroids and long-acting beta-agonists. Linvemastat works by blocking an enzyme called MMP-12, which is believed to contribute to lung inflammation and tissue damage in asthma. The trial is a Phase 2, randomized, double-blind, placebo-controlled study involving approximately 135 participants across multiple global sites. Participants are assigned to receive either 100 mg or 300 mg of linvemastat, or a placebo, once daily for 16 weeks, while continuing their regular asthma medications. Researchers are primarily measuring changes in lung function, specifically the amount of air a person can forcefully exhale in one second (FEV₁), as well as tracking asthma flare-ups, use of rescue inhalers, and markers of inflammation. Safety is closely monitored through lab tests, heart monitoring, and physical exams. The goal is to determine whether linvemastat can offer a meaningful new option for patients whose asthma remains difficult to control, potentially improving both respiratory health and overall quality of life.

Progestogen-only hormonal contraception associated with inhibition of ovulation: oral, injectable, implantable. intrauterine device (IUD), intrauterine hormone-releasing system (IUS), bilateral tubal occlusion, vasectomized partner (when partner is the sole sexual partner of the female patient and when the partner has received medical assessment of the surgical success), sexual abstinence.
• Women not of childbearing potential are defined as: Post-menopausal women (defined as at least 12 months with no menses without an alternative medical cause); in women <45 years of age, a high follicle-stimulating hormone (FSH) level in the post-menopausal range may be used to confirm a post-menopausal state in women not using hormonal contraception or hormonal replacement therapy; OR Have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion at least 6 weeks prior to Screening OR Have a congenital or acquired condition that prevents childbearing.

Exclusion Criteria:

• Pregnant or breastfeeding.

• Participation in another clinical trial of an investigational agent within 3 months (small molecule) / 6 months (biologics) or 5 half-lives (if known) of the agent, whichever is longer, prior to randomization.

• Evidence of COVID-19 infection at Screening, as judged by the Investigator.

• Advanced congestive heart failure [New York Heart Association (NYHA) class 3 or 4].
