Lupin Presents Phase 3 Data for Solosec® (secnidazole) Demonstrating Significant Response Rate in Female Patients with Trichomoniasis
Mumbai, Baltimore, August 14, 2020: Lupin Pharmaceuticals Inc. (Lupin) the U.S. based wholly owned subsidiary of Lupin Limited, today announced results from its pivotal Phase 3 clinical trial to assess efficacy and safety of single-dose Solosec® (secnidazole) 2g oral granules in female patients with trichomoniasis, the most common non-viral, curable sexually transmitted infection (STI) in the U.S. The trial results showed a clinically and statistically significant response rate, or microbiological cure, in patients treated with Solosec® as compared to placebo (p<0.001). The data were presented at the 2020 Infectious Diseases Society for Obstetrics & Gynecology (IDSOG) Virtual Annual Meeting.
“The efficacy results of the Phase 3 study are quite encouraging and could support the utility of Solosec® in clinical practice as a treatment option for trichomoniasis once the new indication is approved,” said Christina Muzny, M.D., MSPH, University of Alabama at Birmingham, who presented the abstract at IDSOG. “Trichomoniasis increases risk of HIV infection, disproportionately affects African American women and can lead to adverse health outcomes. It is critical to screen women at high risk and treat with therapy that is convenient to use, to help improve patient compliance.”
Based on the data, Lupin will submit a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (FDA) for Solosec® for the treatment of trichomoniasis later this year. Solosec® is only currently approved by the FDA to treat bacterial vaginosis (BV) in adult women.
The trial titled “A Phase 3, multi‐center, prospective, randomized, placebo‐controlled, delayed treatment, double‐blind study to evaluate the effectiveness and safety of a single oral dose of 2 grams of secnidazole for the treatment of trichomoniasis in women,” met its primary endpoint of microbiological cure at the test-of-cure (TOC) visit on study Day 6-12. Microbiological cure was defined as a negative trichomonas vaginalis culture (i.e., InPouch™ TV test negative for T. vaginalis) in the modified Intent-To-Treat (mITT) population (all randomized subjects who were culture positive for T. vaginalis and negative for gonorrhea and chlamydia at baseline). In the trial, 92.2% of patients in the Solosec® group (59/64) achieved the primary endpoint versus 1.5% (1/67) in the placebo group (p<0.001). In the Per-Protocol population, the cure rate was 94.9% (56/59) for Solosec® versus 1.7% (1/60) for placebo (p<0.001). Solosec® was generally well-tolerated. The most commonly reported adverse events were vulvovaginal candidiasis (2.7%) and nausea (2.7%). No serious adverse events were observed in the trial.
“Trichomoniasis is the most common non-viral, STI that impacts an estimated 3-5 million people in the U.S.,” Gregory Kaufman, M.D., Senior Vice President, Global Clinical and Medical Affairs, Specialty at Lupin said. “We look forward to working with the FDA as we file for this new indication.”
About the Phase 3 Study
The Phase 3 multicenter, randomized, delayed treatment, placebo-controlled, double-blind study enrolled 147 adult female patients to evaluate the effectiveness and safety of a single oral dose of Solosec® (secnidazole) granules for the treatment of trichomoniasis. Subjects were diagnosed with trichomoniasis at the screening visit (Visit 1, baseline) that was confirmed by a positive culture for T. vaginalis. At Visit 1, subjects were randomly assigned in a 1:1 ratio to either Solosec or matching placebo. Subjects were evaluated for TOC at the second visit (Visit 2, Day 6 -12), at which (following sampling for the TOC culture), subjects also received active treatment if they had received placebo at baseline, and subjects received placebo if they had received active treatment at baseline. Subjects were then followed at subsequent visits for resolution of trichomoniasis as well as any need for additional therapy.
Trichomoniasis is the most common non-viral STI in the U.S., and is caused by a protozoan parasite called Trichomonas Vaginalis. An estimated 3 to 5 million people have the infection, with African American women having a nearly ten times higher risk of being affected compared with non-Hispanic white women. Trichomoniasis is four-to-five times more prevalent in women compared to men.3 Signs and symptoms in women can include itching, burning, redness or soreness of the genitals, discomfort with urination and vaginal discharge.1 However, most infected persons (70%-85%) have minimal or no symptoms, and untreated infections might last for months to year.1,,8 Trichomoniasis is associated with a two- to three-fold increased risk of HIV infection,, as well as adverse reproductive health outcomes, including infertility and preterm birth. Up to 53% of women with HIV infection also have T. vaginalis, which is associated with a significantly increased risk of contracting pelvic inflammatory disease (PID). Routine screening of asymptomatic women with HIV infection for T. vaginalis is recommended because of the adverse events associated with asymptomatic trichomoniasis and HIV infection.8 Patients receiving care in high-prevalence settings (e.g. STD clinics) and asymptomatic patients at high risk for infection (e.g., persons with multiple sex partners, history of STDs) may also be considered for screening.8
Solosec® (secnidazole) 2 g oral granules is a 5-nitroimidazole antimicrobial agent indicated for the treatment of BV in adult women.
