Item 8.01 | Other Events. |
On July 29, 2019, the Company reported topline results from STRIVE B. The Company previously reported topline results from Part A of the STRIVE clinical trial (“STRIVE A”) in March 2018.
STRIVE B was an international, multicenter, double-blind clinical trial evaluating the safety, tolerability and efficacy of once-weekly dosing of rezafungin acetate compared to once-daily dosing of caspofungin in patients with candidemia and/or invasive candidiasis.
STRIVE B enrolled 91 patients in the microbiologicalintent-to-treat, or mITT, population. Patients were randomized to receive either 400 mg of rezafungin administered intravenously once weekly for two to four weeks or daily caspofungin administered intravenously according to the approved prescribing information, with an optional step down to oral fluconazole. To align with the chosen dosing regimen in the Phase 3 program, the STRIVE B trial was amended midway for Group 1 to use rezafungin 400 mg for the first week followed by 200 mg once weekly for up to four weeks in total.
The objective of STRIVE B was to show comparability in efficacy and safety of rezafungin dosed once-weekly and caspofungin dosed once-daily. Efficacy measures in the trial included clearance ofCandida from the blood or other normally sterile sites, resolution of systemic signs attributed to theCandida infection, investigator assessment of clinical response and overall survival. The trial was not statistically powered to demonstrate superiority ornon-inferiority and therefore comparisons of efficacy are directional.
In the STRIVE B trial, rezafungin met all of its objectives for efficacy, safety and tolerability in the treatment of patients with candidemia and/or invasive candidiasis. The trial results show that patients treated with rezafungin had numerically improved outcomes as compared to caspofungin across all efficacy measures at the 400 mg/200 mg dosing regimen. In addition, an analysis combining data across STRIVE A and STRIVE B, demonstrated that rezafungin achieves meaningful improvement in outcomes compared to caspofungin on Clinical Response across all efficacy endpoints at the same 400 mg/200 mg dose.
The charts below illustrate the topline results from STRIVE B and combined results from STRIVE A and STRIVE B for critical measures of efficacy.
All-Cause Mortality – Death through Day 30a
Clinical Cure at Day 14 b
Overall Success at Day 14 c
a | All-Cause Mortality on Day 30 is the primary endpoint for the Phase 3 ReSTORE trial as recommended by the FDA. |
b | Clinical Cure by PI Assessment is the outcome that most closely approximates the primary outcome in prior candidemia/invasive candidiasis clinical trials and primary endpoint for EMA for the Phase 3 ReSTORE trial. |
c | Overall Success is defined as the resolution of attributable systemic signs of candidemia/invasive candidiasis present at baseline plus mycological eradication. |
There were no unanticipated or concerning adverse event trends among STRIVE B trial participants. Thetop-line results indicate that rezafungin was safe and well-tolerated at both dosing regimens. As expected, and observed in STRIVE A, treatment emergent adverse events (TEAEs) in the study population were observed in most patients, though study drug-related adverse events were substantially lower, with a frequency of 6.5 percent, 0 percent and 14.7 percent in the 400 mg/400 mg, 400 mg/200 mg, and caspofungin groups respectively.
