(NASDAQ: DARE), a purpose-driven health biotech company solely focused on closing the gap in women’s health between promising science and real-world solutions, today announced the initiation of its Phase 2 clinical study of DARE-HPV, an investigational, proprietary fixed-dose formulation of lopinavir and ritonavir in a soft gel vaginal insert, designed to evaluate DARE-HPV as a potential treatment for persistent high-risk human papillomavirus (HPV) infection. DARE-HPV is being developed as a non-surgical, localized, self-administered therapy designed to clear persistent high-risk HPV infection. HPV infection is the underlying cause of 99% of cervical cancer cases in the United States. There are currently no FDA-approved pharmacologic treatments for HPV infection. The Phase 2 study is a randomized, placebo-controlled, double-blind trial designed to evaluate the safety and antiviral activity of a lower and higher DARE-HPV dose compared with placebo in approximately 100 women with confirmed persistent high-risk HPV infection over an up to 21-day course of daily treatment. The primary endpoint is HPV clearance rate at three months post treatment. Secondary endpoints include safety, tolerability, and reduction in viral load. Daré Bioscience expects to report topline data in 2027. Study initiation follows clearance by the U.S. Food and Drug Administration (FDA) of the Investigational New Drug (IND) application for the study, announced in February 2026, and represents a significant clinical development milestone. By targeting the virus itself rather than waiting for cellular changes to develop, DARE-HPV has the potential to redefine the treatment paradigm in cervical disease prevention. If approved, DARE-HPV could be the first FDA-approved pharmacologic treatment for HPV infection, addressing a substantial unmet need, with more than 6 million women per year in the United States estimated to acquire a high-risk HPV infection. “Initiating this Phase 2 study marks a historic step — for the first time, women with persistent high-risk HPV infection may have access to this pharmacologic treatment as part of a clinical trial," said Sabrina Johnson, President and CEO of Daré Bioscience. “For decades, women have been told to ‘watch and wait’ to see if the virus clears on its own or the infection progresses to precancerous lesions on the cervix. DARE-HPV is designed to intervene earlier – targeting the virus itself before progression to cervical disease – aiming to eliminate the frequent ‘watchful waiting’ visits to a health care provider that are costly, burdensome, and contribute to socioeconomic and racial disparities in cervical cancer. We are grateful to ARPA-H, our clinical investigators, and most importantly, to the women who will participate in this study.” HPV is one of the most common sexually transmitted viral infections worldwide. An estimated over 11 million women in the U.S. alone acquire a new HPV infection every year. While most HPV infections resolve spontaneously, an estimated 6 million of those women per year experience “high-risk” HPV infection, or an HPV infection caused by one of the carcinogenic HPV types, that can progress to precancerous cervical lesions and, ultimately, cervical cancer if left untreated. According to the Centers for Disease Control and Prevention, high-risk HPV types are responsible for nearly all cases of cervical cancer in the United States. Persistent high-risk HPV infection refers to testing positive for a high-risk HPV type at consecutive timepoints for at least 12 months. Today, the standard of care does not treat the virus. Instead, women with high-risk HPV infection are monitored through repeated screening. Intervention typically occurs only after precancerous lesions develop, often requiring surgical procedures such as excisional or ablative treatments of cervical tissue. These procedures may increase the risk of preterm birth in future pregnancies and can pose risks to fertility – creating a significant physical and emotional burden for women. Persistent high-risk HPV infection represents a substantial unmet medical need: <ul type="disc"><li>High-risk HPV types cause virtually all cases of cervical cancer</li><li>There are no FDA-approved pharmacologic treatments for high-risk HPV infection</li><li>Current intervention strategies rely on surgical removal of abnormal cervical tissue</li><li style="margin-bottom:10pt;">Surgical procedures are associated with increased risks of preterm birth and potential impacts on fertility </li></ul> The Phase 2 clinical study, as well as the broader DARE-HPV program, is supported by a $10 million contract funded by the Advanced Research Projects Agency for Health (ARPA-H), part of the U.S. Department of Health and Human Services. Daré has received $9 million of this award to date and expects to receive the remaining funding as program milestones are achieved. “This program reflects our commitment to advancing science where women have historically had limited or no therapeutic options,” Johnson added. “With ARPA-H support and initiation of this Phase 2 study, we are positioned to generate clinical data that could meaningfully advance a product candidate with the potential to change how persistent high-risk HPV infection is managed.” Additional details regarding the Phase 2 study will be available at <a href="https://www.globenewswire.com/Tracker?data=6Di0HZAFaR6UloQxP95EJLdTCGS3tcqZ_MukOWfC1MXDIsIG05St-kUuUeuBGa5mXUg8nX1tbi6pjKJEc2K445RG7-WmO3Tej00DsxpGK1I=" rel="nofollow" target="_blank" title="www.ClinicalTrials.gov">www.ClinicalTrials.gov</a>. Daré Bioscience expects to report topline data from the Phase 2 study in the 2027 and will provide updates on study progress in the interim. About DARE-HPV DARE-HPV is an investigational, proprietary fixed-dose formulation of lopinavir and ritonavir in a soft gel vaginal insert being developed as a non-surgical, localized, self-administered therapy for clearance of persistent high-risk HPV infection. Lopinavir and ritonavir are protease inhibitors with established antiviral activity. DARE-HPV development has been supported by a $10 million contract funded by ARPA-H. If clinically successful and approved, DARE-HPV could be the first FDA-approved pharmacologic treatment for HPV infection. There are currently no FDA-approved pharmacologic treatments for HPV infection. About Daré Bioscience Daré Bioscience is a purpose-driven health biotech company solely focused on closing the gap in women’s health between promising science and real-world solutions. Every innovation Daré advances is based in advanced science and backed by rigorous, peer-reviewed research. From contraception to menopause, pelvic pain to fertility, vaginal health to infectious disease, Daré is working to close critical gaps in care using science that serves her needs. For decades, women have been told to “wait it out” or “live with it,” while innovations that could improve their quality of life languish in the regulatory or funding pipeline. With growing awareness around menopause, sexual health, and vaginal health, the conversation is shifting. However, access to real, evidence-based solutions continues to lag. Daré was founded to change that. As a female-led health biotech company, Daré is accelerating the development of credible, science-based solutions that meet the high standards of clinical rigor – randomized, controlled trials; validated endpoints; peer-reviewed publications; and current Good Manufacturing Practice (cGMP) requirements.
