New drug aims to tame severe viral lung infections
NCT ID NCT07633288
First seen Jun 27, 2026 · Last updated Jul 29, 2026 · Updated 2 times
Summary
This study tests whether a daily pill called AP1189 can help hospitalized patients with breathing failure due to viruses like flu, RSV, or COVID-19. About 96 adults will receive either AP1189 or a placebo for 14 days, on top of usual care. The main goal is to see if the drug reduces serious outcomes like death, need for a breathing machine, or kidney failure within 28 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- AP1189 (a melanocortin agonist pill)
- What this could lead to
- If it works, this could point toward a new add-on treatment to reduce severe complications from respiratory viral infections like flu, RSV, or COVID-19.
- What could go wrong
- This is an early Phase 2 proof-of-concept trial with only 96 participants, so results may not apply broadly. The drug is tested on top of standard care, and its benefit over placebo is uncertain.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Written informed consent has been obtained prior to initiating any study-specific procedures * Expected respiratory viral infection, and positive for either SARS-COV-2, Influenza A or B, or RSV as confirmed by a bedside LAF test, qualitative PCR, or quantitative PCR (Q-PCR). * Hospitalized with respiratory insufficiency expected to be caused by respiratory viral infection defined by SpO2 ≤ 93 % on ambient air or supplementary oxygen supply via nasal catheter or facial mask (WHO Clinical Progression Scale score 5 or 6). Or in participants with hypercapnic respiratory failure (usually due to COPD) the SpO2 threshold is SpO2 ≤ 85 %. * Duration of disease from first symptom\< 15 days before enrolment * Females of childbearing potential using reliable means of contraception or are post-menopausal or are surgically sterilized * Females of childbearing potential with a negative pregnancy test at screening and baseline * As the morbidity and mortality of respiratory infections are many fold increased in vulnerable participants, vulnerable participants are not excluded but included as subgroups. * Screened within 24 hours of hospital admission to the hospital, or within 24 hours of receiving a patient, if the patient is transferred from another hospital or another hospital department due to respiratory distress Exclusion Criteria: * In the investigator's opinion, progression to death is imminent and inevitable irrespective of the provision of treatment * Already meeting any component of the primary composite endpoint at screening, defined as the presence of any of the following: invasive mechanical ventilation, ECMO, cardiovascular organ support (balloon pump or inotropes/vasopressors), or renal failure (Cockcroft-Gault estimated creatinine clearance \<15 ml/min, haemofiltration or dialysis). Note: participants qualifying under inclusion criterion 8b (pre-existing renal insufficiency or dialysis) are excluded only if they meet any of the other criteria (invasive mechanical ventilation, ECMO, or cardiovascular organ support). Participants who are physically located in an ICU or HDU but do not meet the above physiological criteria are not excluded on that basis alone. * Participating in other drug clinical trials * Any condition that in the view of the screening physician would suggest that the participant is unable to comply with study protocol and procedures * Participants who have initiated treatment within 3 months prior to screening with immunosuppressive or immunomodulatory treatments for chronic autoimmune diseases. Administration of steroids or other immunosuppressive medicines implemented as standard-of-care for the treatment of the respiratory viral infection is acceptable. Asthma/COPD participants are allowed to use their habitual inhalation spray containing adrenocortical hormone. * Pregnant women or nursing (breastfeeding) mothers
