Brief Summary

Acute respiratory distress syndrome (ARDS) is a life-threatening condition with a diffuse, inflammatory form of lung injury, causing pulmonary infiltration and respiratory failure leading to poor oxygenation. It is a rapidly progressive form of respiratory failure and accounts for approximately 10% of admissions to the intensive care unit (ICU) and has a high mortality (40%) in severe cases. Globally, approximately 3 million ARDS cases are reported each year, with around 200,000 cases seen in the United States.

The etiology of ARDS could be pulmonary or extra-pulmonary. Patients with ARDS have symptoms like difficulty in breathing, shortness of breath, and cyanosis, and they may require assisted breathing/ventilatory support/extracorporeal membrane oxygenation. About 25% of ARDS patients need mechanical ventilation to support breathing; however, a ventilator-induced lung injury (VILI) is known to further exacerbate ARDS in many of them. In recent decades, numerous efforts have been made to develop therapies for treating/managing ARDS. Unfortunately, they have been largely unsuccessful or inconclusive, and at present, no effective pharmacological therapy for ARDS is available. Hence, development of better therapeutics for ARDS is an unmet need.

Centhaquine is a first-in-class resuscitative agent for hypovolemic shock approved for marketing in India. Centhaquine has been found to be an effective resuscitative agent in rat, rabbit, and swine models of hemorrhagic shock. Its safety and tolerability have been demonstrated in a human phase I study in 25 subjects (CTRI/2014/06/004647). Results from multicentric, randomized, double-blind, parallel, controlled clinical phase II (CTRI/2017/03/008184) and phase III (CTRI/2019/01/017196) studies conducted in India indicate that centhaquine is a novel, first-in-class, highly effective resuscitative agent for hypovolemic shock. A total of 155 patients with hypovolemic shock have been studied in the combined phase II and III trials, while a multicentric phase IV study (NCT05956418) in 400 patients with hypovolemic shock is currently being conducted in India. The outcomes of the completed trials indicate that centhaquine is safe and reduces mortality significantly (P=0.0271) compared to standard treatment of hypovolemic shock. In the phase II and III studies, ARDS and MODS were evaluated as secondary endpoints. Centhaquine provided hemodynamic stability and significantly reduced ARDS and multiple organ dysfunction score (MODS) in patients enrolled in these trials, which suggests that centhaquine has potential beyond treating hypovolemic shock and could be useful for ARDS treatment. Centhaquine is likely to provide hemodynamic stability, improve tissue oxygenation, reduce pulmonary edema, reduce ARDS score, and reduce MODS in patients with ARDS.

Detailed Description

This is a multicentric, randomized, double-blind, placebo-controlled phase-II clinical study to assess the safety and efficacy of centhaquine as an adjuvant to the standard of care in patients with moderate to severe ARDS. Approximately 10 study centers in the United States will participate in the study. For an individual patient, the duration of the study will be 60 days, including 3 study visits: visit 1/Day 1 (screening/randomization/baseline/treatment visit), visit 2/Day 28, and visit 3/End of Study (Day 60). At visit 1, approximately 80 eligible patients will be randomized 1:1 into 2 treatment groups of 40 each after meeting the eligibility criteria. A total of 40 patients will be enrolled in the centhaquine group (Group 1) and a total of 40 patients in the control group (Group 2):

• Group 1 (Active Group): Centhaquine (Dose: 0.01 mg/kg) + Standard of care
• Group 2 (Control group): Equal volume of Normal Saline + Standard of care In both treatment groups, patients will be provided with the standard of care. Centhaquine or Equal volume of Normal Saline will be administered intravenously after randomization to patients meeting the eligibility criteria. In the centhaquine group, centhaquine (0.01 mg/kg) dose will be administered as an intravenous (IV) infusion over 1 hour in 100 mL of normal saline. An additional dose of centhaquine will be administered on Day 2 if oxygenation and/or vasopressor support is required, but not before 24 hours of the previous dose (maximum 2 doses at an interval of 24 hours can be administered). In the control group, equal volume of normal saline will be administered as an intravenous (IV) infusion over 1 hour post-randomization. Conditions of administration will remain the same as for the centhaquine group. All subjects will be closely monitored during and after infusion. Vital signs will be monitored every 10 minutes during infusion. In the event of worsening hemodynamics or respiratory status, the infusion will be discontinued. Each subject will be monitored closely and followed up throughout his/her hospitalization. Moreover, he/she will be assessed for safety and efficacy parameters over 60 days from randomization.
