Mumbai, Baltimore: Lupin Pharmaceuticals, Inc., the U.S. based wholly-owned subsidiary of Lupin Limited (Lupin), announced today that the U.S. Food and Drug Administration (FDA) has accepted their supplemental New Drug Application (sNDA) for Solosec® (secnidazole) for the treatment of trichomoniasis in adults and adolescents. The FDA has assigned a Prescription Drug User Fee Act (PDUFA) target date of June 30, 2021. Trichomoniasis vaginalis is the most common non-viral, curable sexually transmitted infection (STI) in the U.S., affecting an estimated 3 to 5 million people. Solosec® 2 g oral granules is currently FDA-approved to treat bacterial vaginosis (BV) in adult women.
“The FDA acceptance of our application for Solosec® to treat trichomoniasis is an important milestone for our company and for patients who are in need of new options for the treatment of trichomoniasis,” said Jon Stelzmiller, President – Specialty, Lupin Pharmaceuticals, Inc. “We look forward to working with the FDA during their review of our file for this new indication.”
If approved for trichomoniasis, Solosec® could be the only single-dose oral prescription treatment for both BV and trichomoniasis.
The Solosec® sNDA is based, in part, on trial results that showed a clinically and statistically significant response rate, or microbiological cure, in patients treated with Solosec® as compared to placebo (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. The data were presented at the 2020 Infectious Diseases Society for Obstetrics & Gynecology (IDSOG) Virtual Annual Meeting.
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 (T. vaginalis). An estimated 3 to 5 million people have the infection,1 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.2 However, most infected persons (70%-85%) have minimal or no symptoms, and untreated infections might last for months to a year.2,,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. 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., sexually transmitted disease clinics) and asymptomatic patients at high risk for infection (e.g., persons with multiple sex partners, history of sexually transmitted diseases/infections) 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.
DOSAGE AND ADMINISTRATION
Solosec® is a single-dose therapy for oral use. The entire contents of Solosec® packet should be sprinkled onto applesauce, yogurt or pudding and consumed once within 30 minutes without chewing or crunching the granules. Solosec® is not intended to be dissolved in any liquid.
IMPORTANT SAFETY INFORMATION
- Solosec® is contraindicated in patients with a history of hypersensitivity to secnidazole, other ingredients of the formulation or other nitroimidazole derivatives.
- Vulvo-vaginal candidiasis may develop with Solosec® and require treatment with an antifungal agent.
- Potential risk of carcinogenicity is unknown and has not been studied. Carcinogenicity has been seen in rodents chronically treated with nitroimidazole derivatives, which are structurally related to secnidazole. Chronic use should be avoided.
- Breastfeeding is not recommended. Patients should discontinue breastfeeding for 96 hours after administration of Solosec®.
- Most common adverse reactions observed in clinical trials (incidence ≥ 2%) were vulvovaginal candidiasis, headache, nausea, dysgeusia, vomiting, diarrhea, abdominal pain and vulvovaginal pruritus.
