JERSEY CITY, N.J., Aug. 15, 2022 (GLOBE NEWSWIRE) -- SCYNEXIS, Inc. (NASDAQ: SCYX), a biotechnology company pioneering innovative medicines to overcome and prevent difficult-to-treat and drug-resistant infections, today reported financial results for the second quarter ended on June 30, 2022.

“We are pleased to see the improvements to the current sales trajectory, and we are well capitalized with a cash runway into the first quarter of 2024 to execute on the next important steps toward our goal of building a broad, long-lasting antifungal franchise,” said Marco Taglietti, M.D., President and Chief Executive Officer of SCYNEXIS. “For the remainder of the year we will be focused on preparing for the approval of the recurrent VVC indication, while working to enroll invasive candidiasis patients into our MARIO study.”

BREXAFEMME Commercial Update

• BREXAFEMME delivered $1.3 million in net sales in Q2 2022. According to IQVIA data, there were approximately 5,141 total prescriptions for BREXAFEMME written in Q2 2022, a 29 percent increase of total prescriptions over Q1 2022.
• BREXAFEMME was prescribed by over 2,200 individual healthcare professionals (HCPs) in the second quarter, an increase of 25% over Q1 2022.
• Commercial insurance coverage of BREXAFEMME continues to expand. As of June 2022, BREXAFEMME was covered by plans representing more than 109 million or 60% of commercially-insured lives, a 17% increase over the 93 million covered lives as of Q1 2022.

Ibrexafungerp Clinical Updates

• In August 2022, SCYNEXIS announced that the U.S. Food and Drug Administration (FDA) accepted the Company’s submission of a supplemental NDA for a labelling expansion for BREXAFEMME for the prevention of recurrent VVC. The FDA granted the submission Priority Review and assigned the Prescription Drug User Fee Act (PDUFA) target decision date as November 30, 2022.

• Initiated enrollment in MARIO, a global Phase 3 study to evaluate ibrexafungerp as an oral step-down treatment for invasive candidiasis (IC) in the hospital setting. SCYNEXIS anticipates study completion and results to enable regulatory filing and potential approval for IC, including candidemia, in 2024. If approved, oral ibrexafungerp would be the first non-azole oral therapy available for invasive candidiasis and would enable an IV-to-oral transition with a consistent mechanism of action. Like IV-only echinocandins, oral ibrexafungerp acts via glucan synthase inhibition, a mechanism which has been demonstrated to be the most effective for treating invasive Candida infections.

• Initiated enrollment in a new Phase 3b, open-label, multicenter study (VANQUISH) to evaluate the efficacy, safety and tolerability of oral ibrexafungerp as a treatment for vulvovaginal candidiasis (VVC) in patients who have failed treatment with fluconazole, based on mycological and clinical outcomes. The VANQUISH study will enroll approximately 150 patients with complicated VVC who have failed fluconazole treatment and who will receive 600 mg of oral ibrexafungerp for one, three or seven consecutive days determined by their underlying complicating condition including immunocompromised state. Complicated patients include patients with recurrent VVC, those with VVC caused by non-albicans Candida species, and those with diabetes, immunocompromising conditions (e.g., HIV), or immunosuppressive therapy (e.g., corticosteroids).
• Achieved target enrollment of 200 patients for its Phase 3 FURI study evaluating oral ibrexafungerp for the treatment of patients with severe fungal infections who are either intolerant to standard antifungal therapy or experience refractory fungal infections despite treatment, including those caused by Candida auris (C. auris). SCYNEXIS anticipates study closure activities to commence by the end of 2022 and also is on track to complete enrollment in the CARES trial during second half of 2022.
• Following the positive Phase 1 data with the IV formulation reported previously, SCYNEXIS is preparing for discussions with FDA regarding the next stage of development.

Ibrexafungerp Scientific Presentations and Publications

• Presented positive outcomes from its global Phase 3 CANDLE study investigating the safety and efficacy of oral ibrexafungerp for prevention of recurrent vulvovaginal candidiasis (RVVC), also known as vaginal yeast infection. The results were presented during the Infectious Diseases Society for Obstetrics and Gynecology (IDSOG) Annual Meeting held in Boston August 4-6, 2022. The study met its primary endpoint, with 65.4% of patients who received monthly single-day ibrexafungerp treatment achieving clinical success with no recurrence at all, either culture-proven, presumed or suspected, through Week 24. In addition, ibrexafungerp demonstrated superiority over placebo in preventing mycologically proven recurrence of RVVC through Week 24, a key secondary endpoint. No mycologically proven recurrence was detected in 70.8% of patients receiving ibrexafungerp. The advantage of ibrexafungerp over placebo was sustained over the three-month follow-up period and remained statistically significant in both primary and secondary endpoints (p=0.034 and 0.029, respectively). In the study, ibrexafungerp was generally safe and well-tolerated. There were no serious drug-related adverse events, and no patients treated with ibrexafungerp discontinued therapy due to adverse events. The most commonly-reported adverse events, headaches and gastrointestinal in nature (i.e., diarrhea, nausea), were mostly mild and generally consistent with the current approved product label.

• Presented positive outcomes from the CANDLE nested sub-study investigating oral ibrexafungerp in patients with recurrent vulvovaginal candidiasis (RVVC) who failed fluconazole treatment. The results were presented during the International Society for the Study of Vulvovaginal Diseases (ISSVD) XXVI World Congress and International Vulvovaginal Disease Update 2022 held in Dublin, Ireland, July 15-20, 2022. Data show that 71% of 24 patients with recurrent vulvovaginal candidiasis (RVVC) who failed to respond to a three-day regimen of fluconazole achieved a substantial reduction or complete elimination of signs and symptoms after receiving a one-day treatment with ibrexafungerp.

• Reported new positive outcomes in patients with refractory vulvovaginal candidiasis (VVC) treated with oral ibrexafungerp from the ongoing Phase 3 FURI study. The new interim analysis was presented during the American College of Obstetricians and Gynecologists (ACOG) Annual Clinical & Scientific Meeting held in San Diego May 6-8, 2022. Ibrexafungerp showed positive results in difficult-to-treat VVC patients with severe fungal infections who were either intolerant to standard antifungal therapy or experienced refractory infections despite treatment. Of the 14 patients in the FURI study with refractory or relapsed cases of VVC treated with ibrexafungerp, 10 (71.4%) had successful clinical outcomes as judged by an independent Data Review Committee. Patients with VVC received 750 mg of oral ibrexafungerp (375 mg twice a day) every 72 hours for a total of three dosing days (Day 1, Day 4 and Day 7). In the study, ibrexafungerp was generally safe and well-tolerated with findings consistent with the existing product label.

• Presented positive interim analyses of data from its ongoing Phase 3 FURI and CARES studies at the 32nd Annual European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) held in Lisbon, Portugal April 23-26, 2022. In an interim analysis of the CARES study of 18 enrolled patients with candidemia and other infections caused by Candida auris (C. auris) treated for a mean duration of 18 days, 78% of patients showed complete or partial response and 11% had stable disease. An interim analysis was conducted with combined data of 49 patients with invasive candidiasis and candidemia from the ongoing Phase 3 FURI (n=39) and CARES (n=10) studies. Aggregate data from the two studies showed that of the patients treated with ibrexafungerp, 68% had complete or partial response and 14% had stable disease.

• Additional preclinical data presented at ECCMID from an in vivo mouse model of pulmonary mucormycosis support ibrexafungerp as an effective potential treatment for mucormycosis. The study also demonstrated in vivo efficacy of ibrexafungerp monotherapy in treating both Rhizopus delemar and Mucor circinelloides infections in mice, consistent with other antifungals currently used against mucormycosis. Additionally, the study found that when ibrexafungerp was combined with liposomal amphotericin B or posaconazole, synergistic benefits were observed with a significant enhancement in median survival time and overall survival when compared to any one therapy alone (p
