About

This study is designed as a 2-part, 2-cohort, double-blind, randomized, placebo controlled, multicenter Phase 1/2 study to evaluate the safety, tolerability and efficacy of RJX in patients with COVID-19.

Full description

For each cohort, there will be an open label Safety Lead-in (Part 1) and a placebo controlled, randomized, double-blind portion (Part 2). In Part 1, RJX will be administered daily for 7 days. In the active treatment arm of Part 2 for both cohorts, RJX will be administered daily for 7 days per cycle and patients may receive up to 2 cycles. As detailed below, patients will be allowed to receive a second 7 day cycle of therapy based on the medical judgment of the Investigator. The total RJX exposure during Part 2 could therefore be up to 14 days. Both cohorts will start and enroll in parallel and independently. A safety follow-up period will begin at Day 14/Discharge, or when treatment is discontinued, and will continue for approximately 60 days post discharge. Part 1 will be conducted at a single site and Part 2 will be conducted at multiple sites. The 2 cohorts in this study are:

• Cohort 1:

  • Hospitalized COVID-19 patients ≥18 years without hypoxemia who are either not receiving any oxygen therapy OR are receiving supplemental oxygen via mask or nasal prongs (namely, clinical status score 4 or 5 on an 8-point ordinal scale).

  • Patients are required to have the following high-risk characteristics

    1. Age ≥65 years AND type 2 diabetes or hypertension OR

    2. Age ≥18 years with abnormal blood tests AND CRP >50 mg/L PLUS at least 1 of the following biomarkers:

       1. D-dimer >1,000 ng/mL,
       2. Ferritin >500 µg/L,
       3. High sensitivity cardiac troponin >2 × upper limit of normal (ULN),
       4. LDH >245 U/L.

• Cohort 2:

  • Hospitalized COVID-19 patients with hypoxemia without ARDS who are receiving either non-invasive positive pressure ventilation (NIPPV) OR high flow oxygen (namely, clinical status score 3 on an 8-point ordinal scale).

Enrollment: 237 estimated patients

3. On extracorporeal membrane oxygenation
4. Uncontrolled hypertension (systolic blood pressure [BP] >150 mmHg and/or diastolic BP >100 mmHg), unstable angina, congestive heart failure of New York Heart Association Classification Class III or IV (i.e., Class III: marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g., walking short distances [20 100 m], comfortable only at rest; Class IV: severe limitations, experiences symptoms even while at rest, mostly bedbound patients), serious cardiac arrhythmia requiring treatment (exceptions: atrial fibrillation, paroxysmal supraventricular tachycardia), history of myocardial infarction within 12 months prior to enrollment
5. Subjects with a history of congenital long QT syndrome or of Torsades de pointes; subjects with bradycardia (<60 bpm), heart block (excluding 1st degree block, being PR interval prolongation only); subjects with any of the following findings on electrocardiogram (ECG): QTc interval >470 msec in women OR >450 msec in men; subjects requiring any drugs known to prolong the QTc interval, including antiarrhythmic medications
