Lupin Announces Positive Topline Results from its Phase 3 Study of Single-Dose Solosec® (secnidazole) for the Treatment of Trichomoniasis

• Primary endpoint successfully achieved in Phase 3 clinical trial of 147 patients
• Solosec® 2g oral granules was generally well-tolerated among study subjects
• Lupin plans to submit a supplemental New Drug Application for Solosec® to the U.S. FDA for the treatment of trichomoniasis in H2 2020

Mumbai, May 06, 2020: Lupin Pharmaceuticals Inc. (Lupin)  the U.S. based wholly owned subsidiary of Lupin Limited, today announced positive top-line results from its pivotal Phase 3 clinical trial to assess efficacy and safety of single-dose Solosec® (secnidazole) 2g oral granules in 147 female patients with trichomoniasis.Trichomoniasis is the most common non-viral, curable, sexually transmitted infection (STI) in the U.S. The trial demonstrated a clinically and statistically significant response rate, or microbiological cure, in patients dosed with Solosec® as compared to placebo (p<0.001). Based on the data, Lupin plans to submit a supplemental New Drug Application (sNDA) to the U.S. Food and Drug Administration (U.S. FDA) for Solosec® for the treatment of trichomoniasis in the second half of 2020. Solosec® is approved by the U.S. FDA to treat bacterial vaginosis (BV) in adult women.

The trial met its primary endpoint of microbiological cure at the test-of-cure (TOC) visit on study Day 6-12, defined as a negative Trichomonas vaginalis culture. The predefined primary efficacy endpoint, defined as Microbiological Cure (i.e., InPouch™ TV test negative for T. vaginalis) at the Test-Of-Cure visit (Day 6-12) 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), was 92.2% (59/64) for Solosec®  (secnidazole) versus 1.5% (1/67) for placebo  (p<0.001). In the Per-Protocol population, the cure rate was 94.9% (56/59) for Solosec® (secnidazole) versus 1.7 % (1/60) for placebo (p<0.001). Solosec® (secnidazole) was generally well-tolerated with the most commonly reported adverse events being vulvovaginal candidiasis (2.7%) and nausea (2.7%). No serious adverse events were observed.

“Trichomoniasis impacts an estimated 3 to 5 million people in the U.S.,” Gregory Kaufman, M.D., Senior Vice President, Global Clinical and Medical Affairs, Specialty at Lupin said. “We are encouraged by the topline results of our clinical trial, look forward to finalizing the analysis, and working with the FDA to provide a new single-dose therapy option to physicians and patients, to treat this disease.”

About the Phase 3 Study

The Phase 3 trial is a multicenter, randomized, delayed treatment, placebo-controlled, double-blind study to evaluate the effectiveness and safety of a single oral dose of Solosec® (secnidazole) granules for the treatment of trichomoniasis in adult women. Subjects included female patients with a diagnosis of 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.

About Trichomoniasis

Trichomoniasis is the most common non-viral sexually transmitted infection (STI) in the U.S.,and is caused by a protozoan parasite called Trichomonas vaginalis.[i]An estimated 3 to 5 million people have the infection,[ii]with African American women having a nearly ten times higher risk of being affected compared with non-Hispanic white women.[iii]Trichomoniasis is four-to-five times more prevalent in women compared to men.³Signs and symptoms in women can include itching, burning, redness or soreness of the genitals, discomfort with urination and vaginal discharge. 1However, most infected persons(70%-85%)have minimal or no symptoms, and untreated infections might last for months to year.1^,[iv],8Trichomoniasis is associated with a two- to three-fold increased risk of HIV infection,[v]^,[vi]as well as adverse reproductive health outcomes, includinginfertility andpreterm birth.[vii]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).[viii]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.⁸Patients 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
