JUST BREATHE, Breathing Life Into Innovative Therapies for ARDS (Master Record)
Purpose
This is a Phase 2 multicenter, randomized, double-blinded, placebo-controlled study that will evaluate the safety and efficacy of host-directed therapeutics in hospitalized adults diagnosed with Acute Respiratory Distress Syndrome (ARDS) utilizing a platform trial design. Participants will be randomized to receive either a placebo or one of the active treatments. This record describes the default procedures and analyses for all cohorts. Each specific cohort may have additional eligibility requirements, safety and efficacy procedures, or endpoints, which will be described in the corresponding intervention-specific records on clinicaltrials.gov listed below in the detailed description.

Inclusion Criteria
- Participant (or their Legally Authorized Representative (LAR)) provides informed consent and agrees to comply with protocol requirements - Participant is at least 18 years of age or older at the time of consent. - Participant with signs and symptoms of ARDS according to the Berlin definition of ARDS. Note that participants on noninvasive ventilation may be screened. - Participant of childbearing potential must agree to either abstinence or use at least one primary form of contraception, not including hormonal contraception, from the time of screening through Day 28. Additional cohort-specific requirements may apply - Participant agrees to not participate in another investigational interventional study while participating in this study (i.e., through Day 90).
Exclusion Criteria
- Participant with ARDS or at risk of developing ARDS due to the following reasons: trauma, large volume aspiration, or transfusion. - Participant with pulmonary edema due to cardiogenic pulmonary edema/fluid overload or hypoxemia primarily attributable atelectasis, in the absence of a predisposing risk factor for ARDS. - Participant who demonstrates an improvement in oxygenation and ventilatory support 24 hours prior to or during screening up to randomization, such that per investigator clinical judgement, the participant is expected to have significant improvement in lung function over subsequent 24 hours regardless of additional interventions. - Participant is known to be pregnant, nursing, or with a positive (urine and/or serum test) pregnancy test. - Participant is anticipated to be transferred to another hospital which is not a study site within 72 hours. - Participant is not expected to survive for 72 hours. - Participant has been on invasive mechanical ventilation or ECMO for more than 48 hours for ARDS at the time of consent. - Participant has an underlying clinical condition where, in the opinion of the Investigator and based on their clinical judgement, it would be extremely unlikely that the participant would come off ventilation - Participant has severe COPD requiring continuous long-term home oxygen therapy or mechanical ventilation (noninvasive ventilation or via tracheotomy) except for CPAP or bi-level positive airway pressure used solely for sleep-disordered breathing. - Participant has interstitial lung disease or idiopathic pulmonary fibrosis requiring continuous chronic home oxygen therapy. - Participant has NY Heart Association Class IV congestive heart failure. - Participant has a known allergy to any study medication or any of its excipients. - Participant is receiving systemic immunosuppressive therapy for solid organ or hematopoietic cancer or transplant anti-rejection medication. NOTE: Patients on chronic low dose immunosuppressive therapy may be enrolled at the discretion of the investigator in consultation with the medical monitor. - Participant is undergoing active cancer systemic chemotherapy. - Participant received treatment with an investigational immunomodulator or immunosuppressant drugs within 5 half-lives or 30 days (whichever is longer) before randomization. - Participant with concurrent infections or history of the following: 1. Known active tuberculosis, 2. Known active Hepatitis B, or 3. HIV and a CD4 count less than 50 or a detectable viral load of >200 copies/mL HIV RNA. - Participant received treatment with any other investigational drugs within 30 days prior to consent. - Participant had a history of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess within 28 days of screening or inadequate wound healing secondary to major thoracoabdominal surgery at the time of screening. - Participant is considered by the investigator, for any reason, to be an unsuitable candidate for the study. Participant may have additional cohort-specific requirements.

- Masking
- Triple (Participant, Care Provider, Investigator)
- Masking Description
- The overall 2-step randomization scheme will be implemented. - Randomization Level 1 will be open-label, assigning an eligible patient to one of the available treatment cohorts. - Randomization Level 2 will be double-blinded and will randomize participants at a 1:1 ratio to receive either IP or placebo within a specific cohort. Thus, the PPD blinded team, site blinded staff members, and participants/legal authorized representative will be considered blinded to study treatment assignment (either IP or placebo) throughout the course of the study. To preserve the integrity of the study blind, an unblinded pharmacist at each site will be responsible for the reconstitution and dispensation of all study drugs and placebos and will endeavor to ensure that there are no observable differences between the treatment groups (IP or placebo) when dispensing the study materials.

Detailed Description
This is a master protocol for a Phase 2 platform clinical trial to evaluate host-directed therapeutic candidates (i.e., investigational product, IP) for the treatment of hospitalized participants diagnosed with ARDS. The safety and efficacy of each IP will be studied within its own cohort (IP versus Placebo). All patients will continue to receive standard treatments for ARDS as per the investigator. An individual participant will complete the study in approximately 90 days. The study will include a screening period (<24 hours from providing informed consent to treatment), in-hospital treatment period with IP/placebo starting on Day 1 through discharge from the hospital, and a follow-up period after discharge from the hospital through the end of study (Day 90 + 2 weeks). Outcome data will be assembled for each patient over time (such as ventilatory status, oxygenation, and survival). Functional status using the WHO Ordinal scale and Karnofsky scale will be collected. Resource utilization will be calculated (length of stay in a critical care setting, days intubated, and survival). All participants will undergo a series of physical exams, laboratory assessments/biomarker collections, ECG, Chest X-ray or CT scan, and questionnaires through Day 90. Exploratory biomarkers will be evaluated over time to facilitate clinical learning.
