简要总结
This Phase IIa pilot study is a placebo controlled, multicenter study to evaluate safety and efficacy of aerosolized BIO-11006 Inhalation Solution in ARDS patients. The subjects will be randomized 1:1 to either BIO-11006 125 mg twice daily plus standard of care or placebo plus standard of care. The treatment will continue for up to 28 days. The study will enroll up to 40 adult ARDS patients in up to eight sites within USA.
详细描述
This is a randomized, double blind, placebo controlled, parallel-group Phase IIa pilot study of aerosolized BIO 11006 in patients with sepsis-induced acute respiratory distress syndrome (ARDS). All patients enrolled in the study will be ventilated. To be eligible for enrollment, patients must be adults who have sepsis-induced ARDS within 48 hours prior to enrollment, require intubation, and exhibit bilateral infiltrates consistent with pulmonary edema on the frontal chest radiograph within 48 hours of enrollment. Patients will be randomized in a 1:1 ratio to either BIO-11006 125 mg twice daily (BID) plus standard of care ventilation or placebo (half normal saline [HNS]) BID plus standard of care ventilation. Patients randomized to receive BIO-11006 or placebo will start dosing at the time of ventilation and continue for up to 28 days or length of ventilation (if shorter). Patients in both groups will receive best available standard of care treatment, including low-volume mechanical ventilation as indicated by clinical judgment and patient response. The maximum duration of treatment will be 30 days.
The primary objective of this study is to evaluate the safety and efficacy of aerosolized BIO-11006 at a dose of 125 mg BID in ventilated patients who have ARDS. Safety is the primary endpoint in this study and will be monitored by adverse event reporting, oxygenation, mortality, vital signs, ventilator-free days, and ICU-free days.
This study will enroll up to 40 adult patients with ARDS induced by sepsis who first met the Berlin Criteria for ARDS within 48 hours of enrollment, and who require intubation and exhibit bilateral opacities consistent with pulmonary edema on frontal chest radiograph within 48 hours of enrollment.
BIO 11006 Inhalation Solution drug product is formulated at a dosage strength of 41.67 mg/mL (125 mg/3 mL) as an aqueous solution containing sodium chloride and is intended for aerosol administration by the "Aeroneb Pro®" nebulizer to patients randomized to active treatment.

入选标准
- •Has provided (or relative has) written informed consent and authorization for use and disclosure of protected health information
- •Has a clinical diagnosis of sepsis or septic shock defined as:
- •Known or suspected infection
- •Systemic inflammatory response syndrome (SIRS), defined as meeting at least 2 of the following 3 criteria for a systemic inflammatory response:
- •White blood cell count >12,000 or <4,000 or >10% band forms
- •Body temperature >38°C (any route) or <36°C (by core temperatures only: indwelling catheter, esophageal, rectal)
- •Heart rate >90 beats/min or receiving medications that slow heart rate or pace rhythm
- •Enrollment must occur within 48 hours of first meeting ARDS criteria per the Berlin definition of ARDS (ARDS Task Force 2012) and no more than 72 hours from the initiation of mechanical ventilation. (The bilateral opacities, respiratory failure, and decreased P/F ratio must all be present within a 24 hour time period of one another.):
- •Lung injury of acute onset, within 1 week of an apparent clinical insult, with progression of respiratory symptoms
- •Bilateral opacities on chest imaging not fully explained by effusions, lobar/lung collapse, or nodules.
- •Respiratory failure not fully explained by cardiac failure or fluid overload. (Need objective assessment (e.g. echocardiography) to exclude hydrostatic edema if no risk factor present.)
- •Decreased arterial partial pressure of oxygen (PaO2)/ fraction of inspired oxygen (FIO2) ratio while on a minimum Positive End Expiratory Pressure (PEEP) of 5 cm water (H2O):
- •Moderate ARDS: 101 to 200 mmHg (≤ 26.6 kPa)
- •Severe ARDS: ≤ 100 mmHg (≤ 13.3 kPa)
排除标准
- •Age < 18 years or >75 years old
- •Greater than 48 hours since first meeting ARDS criteria per the Berlin definition of ARDS
- •Pregnant or breastfeeding (negative pregnancy test required prior to randomization for female patients of childbearing potential.)
- •Any other irreversible disease or condition for which 6 month mortality is estimated to be > 50%
- •Moderate to severe liver failure (Child Pugh Score > 12)
- •Severe chronic respiratory disease with a PaCO2 > 50 mmHg or the use of home oxygen
- •Patient, surrogate, or physician not committed to full support (exception: a patient will not be excluded if he/she would receive all supportive care except for attempts at resuscitation from cardiac arrest).
- •Major trauma in the prior 5 days
- •Lung transplant patient
- •No consent/inability to obtain consent
- •Moribund patient not expected to survive 24 hours
- •World Health Organization (WHO) Functional Class III or IV pulmonary hypertension
- •No intent/unwillingness to follow lung protective ventilation strategy or fluid management protocol
- •Currently receiving extracorporeal life support or high frequency oscillatory ventilation
- •Known hypersensitivity to BIO 11006
- •Burn victims >20% Total Body Surface Area (TBSA) or with known airway inhalation injury
