Details and patient eligibility

About

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.

Cohort C: Participants will be randomized to receive either a placebo or bevacizumab.

This record describes the default procedures and analyses for Cohort C. Please see NCT06703073 for information on the BP-ARDS-P2-001 Master Protocol.

Full 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. This record only includes information relevant to the bevacizumab cohort.

Inclusion criteria

The following inclusion criteria are in addition to the exclusion criteria specified in the Master Protocol NCT06703073.

ARDS Severity of mild, moderate or severe, based on PaO2/FiO2 or SpO2/FiO2 assessment at the time of randomization.

Exclusion criteria

The following exclusion criteria are in addition to the exclusion criteria specified in the Master Protocol NCT06703073.

Participant has a known allergy or hypersensitivity to the active substance/excipients, or Chinese Hamster Ovary cell products or other recombinant human or humanized antibodies
Participant with established cirrhosis and Child-Pugh Score of 7 or greater
Participant was dialysis-dependent prior to hospitalization. Participant must have a urine dipstick for proteinuria < 2+
The hospitalized participant has a history or currently experiencing the following:
1. Participant must not have an international normalized ratio (INR) >1.5 and/or aPTT >1.5 × upper limit of normal (ULN) within 7 days prior to initiation of study treatment for participants not receiving anticoagulation. For participants on full dose oral or parenteral anticoagulants for therapeutic purposes the INR and/or activated partial thromboplastin time (aPTT) must be within therapeutic limits (according to institution standards) within 7 days prior to initiation of study treatment and the participant on a stable dose of anticoagulants for ≥ 2 weeks prior to initiation of study treatment.
2. Participant with recent serious hemorrhage or history of recent hemoptysis > 2 episodes (defined as ≥2.5 mL of bright red blood per episode) within 1 month of screening.
3. Participant with inadequately controlled hypertension (defined as systolic blood pressure > 150 mmHg and/or diastolic blood pressure > 100 mmHg). Antihypertensive therapy is permitted to achieve these parameters.
4. Participant with a history of hypertensive crisis or hypertensive encephalopathy.
5. Participant with a history of Grade ≥ 4 venous thromboembolisms.
6. Participant with significant vascular disease (eg, aortic aneurysm requiring surgical repair or recent arterial thrombosis) within 3 months of study drug treatment.
7. Participant with history of abdominal fistula, gastrointestinal perforation, intra-abdominal abscess, or active gastrointestinal bleeding within 6 months of study drug treatment.
8. Participant with serious, non-healing wound, active ulcer, or untreated bone fracture.
9. Participant with history or evidence of inherited bleeding diathesis or significant coagulopathy at risk of bleeding (ie, in the absence of therapeutic anticoagulation).
10. Participant with clinically significant cardiovascular disease including cerebrovascular accident or myocardial infarction within previous 6 months, unstable angina, congestive heart failure, or serious cardiac arrhythmia uncontrolled by medication.
11. Participant with a platelet count of <75×109/L.
12. Participant with current or recent (<10 days prior to initiation of study treatment) use of aspirin (>325 mg/day) or clopidogrel (>75 mg/day).
13. Participant is receiving a direct anticoagulant (DOAC) such as dabigatran (Pradaxa®) and rivaroxaban (Xarelto®) without the availability of a reversal agent at the site.
14. Participant is receiving a DOAC such as betrixaban (Bevyxxa®) and edoxaban (Lixiana®) for which there is no approved reversal agent.
