---

On November 26, 2025, Daré Bioscience, Inc. ("we," "us", "our," or the "Company") received notice from Bayer HealthCare LLC ("Bayer") that it was terminating the license agreement between the parties dated January 10, 2020 (the "License Agreement"). In accordance with the terms of the License Agreement, the termination will be effective 90 days from the date we received the notice, or February 24, 2026. Bayer's election to terminate the License Agreement was due to its strategic prioritization.

The License Agreement related to the further development and commercialization of Ovaprene in the U.S. In connection with entering into the License Agreement, we received a $1.0 million upfront non-refundable license fee payment from Bayer, which will be recorded as license revenue upon termination of the License Agreement. Under the terms of the License Agreement, Bayer agreed to support us in development and regulatory activities by providing the equivalent of two experts to advise us in clinical, regulatory, preclinical, commercial, chemistry, manufacturing and controls, and product supply matters, and we agreed to be responsible for the pivotal trial for Ovaprene and for its development and regulatory activities and product supply obligations. As a result of the termination of the License Agreement, we will not be receiving any future license fees or milestone or other payments from Bayer, and all licenses and rights we granted to Bayer will immediately terminate upon termination of the License Agreement.

The foregoing summary of the License Agreement is qualified in its entirety by reference to a copy thereof, which was filed as Exhibit 10.8 to our annual report on Form 10-K, which was filed with the U.S. Securities and Exchange Commission (the "SEC") on March 31, 2025, and is incorporated herein by reference.

We do not expect the termination of the License Agreement to have a material impact on the ongoing pivotal Phase 3 multi-center, single arm, non-comparative clinical study of Ovaprene to evaluate its effectiveness as a contraceptive along with its safety and acceptability (ClinicalTrials.gov ID: NCT06127199). In July 2025, the study's data safety monitoring board (DSMB), an independent group of experts which evaluates the safety and integrity of the study, conducted a planned interim analysis and recommended the study continue without modification. In accordance with the Investigational Device Exemption for Ovaprene, we provided an annual report to the U.S. Food and Drug Administration ("FDA") with data collected from the study through September 15, 2025 regarding safety, tolerability and pregnancy experiences. Such data was consistent with the data analyzed by the DSMB during the July 2025 planned interim analysis. We intend to maintain active recruitment at five study sites, supported by grant funding we received in November 2024. We currently anticipate enrollment will be completed in 2026, and plan to provide further updates regarding anticipated enrollment and study completion targets in 2026.

## Exhibit 99.1

**Exhibit 99.1**

**Daré Bioscience Announces Return of Rights to Ovaprene®; Phase 3 Program Ongoing; Positive Interim Data and Grant Funding Position Asset for Value-Maximization**

**SAN DIEGO, December 1, 2025 — Daré Bioscience, Inc. (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 that all rights to Ovaprene®, the company's first-in-category, investigational, hormone-free monthly intravaginal contraceptive, will be returned to Daré by Bayer HealthCare LLC as a result of Bayer electing to terminate the license agreement between the parties as part of a strategic prioritization. In accordance with the license agreement, the termination will be effective in February 2026. With the Phase 3 program advancing with non-dilutive grant support, the return of rights will provide Daré with full control of a late-stage asset that is differentiated in a large market with significant unmet need.

**Late-Stage, First-in-Category Asset**

The consolidation of commercialization rights will strengthen Daré's strategic position as Ovaprene advances through its pivotal Phase 3 clinical study. Ovaprene has the potential to become the first FDA-approved hormone-free, monthly intravaginal contraceptive option available to women, representing a meaningful innovation in a category that has seen limited advancement in decades.

"We view the consolidation of commercial rights under Daré at this stage of Ovaprene's development as value-enhancing for our company," said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. "The Phase 3 study is progressing, supported by non-dilutive funding, and the positive interim data announced in July 2025 underscore the asset's potential. We will have maximum strategic flexibility to capture the value of this opportunity."

**Positive Interim Results Reinforce Clinical and Commercial Potential**

In July 2025, <u>Daré announced positive interim data</u> from the ongoing open-label Phase 3 trial of Ovaprene (ClinicalTrials.gov ID: NCT06127199) demonstrating encouraging results including consistent safety and tolerability; no serious safety concerns were identified, and overall tolerability was favorable. The rate of pregnancy in women treated in the study at the time of the interim analysis was consistent with the company's expectations based on the results of the pre-pivotal postcoital test <u>clinical study</u> of Ovaprene. These interim findings support Ovaprene's potential as a meaningful hormone-free alternative. These fundamentals remain unchanged, and the study is progressing toward anticipated completion of enrollment in 2026.

The ongoing trial is supported by previously announced external grant funding, including the award from <u>Gates Foundation announced in 2024</u>, and continues without any change to timelines or operations.

**Expanded Strategic Optionality** 

With global commercialization rights consolidated at Daré, the company is now positioned to evaluate partnership structures that best reflect the value of a late-stage, non-hormonal contraceptive with differentiation and relevance. The company believes that Ovaprene will attract broad strategic interest across pharmaceutical and consumer health organizations.

"We believe this development gives us the ability to pursue the most attractive commercial and access pathways for Ovaprene, including partnerships, non-traditional commercialization models, and opportunities to retain greater long-term economics," Johnson added. "This increased optionality, combined with the clinical profile demonstrated to date, positions Ovaprene as one of the most exciting assets in the women's health pipeline."

**Clear Path Forward** 

● Phase 3 study enrollment expected to be completed in 2026

● Continuation of grant funded trial operations

● Premarket approval (PMA) strategy with the FDA's Center for Devices and Radiological Health (CDRH) as lead review division

● Increasing global interest in non-hormonal contraception

● Company will explore partnership and strategic transaction opportunities

**About Ovaprene®**

Ovaprene is an investigational, hormone-free monthly, intravaginal contraceptive that combines physical and chemical mechanisms. Ovaprene features a proprietary knitted polymer barrier to physically block sperm from entering the cervical canal within a silicone-reinforced ring that releases non-hormonal agent ferrous gluconate to impede sperm motility. Unlike current FDA-approved monthly intravaginal contraceptives, Ovaprene does not contain hormones, but consistent with those monthly intravaginal contraceptives Ovaprene is designed to be a "one size fits most" monthly, self-administered product. It is inserted at the end of one menstrual period and left until the beginning of the next, requiring no action at intercourse. It requires no clinician fitting and a new product is used each month. If approved, Ovaprene would represent the first product of its kind for women seeking new options in non-hormonal contraception.

**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.

**Forward-Looking Statements** 

Daré cautions you that all statements, other than statements of historical facts, contained in this press release, are forward-looking statements. Forward-looking statements, in some cases, can be identified by terms such as "believe," "view," "may," "will," "estimate," "continue," "anticipate," "design," "intend," "expect," "could," "plan," "potential," "predict," "seek," "should," "would," "contemplate," "project," "target," "objective," "on track," or the negative version of these words and similar expressions. In this press release, forward-looking statements include, but are not limited to, statements relating to the potential benefits of the return of the rights to Ovaprene to Daré, that Ovaprene will attract broad strategic interest across pharmaceutical and consumer health organizations, the importance of the interim results from the ongoing pivotal Phase 3 trial of Ovaprene to Daré and Ovaprene, Ovaprene's potential as a safe and effective first-in-category, hormone-free, intravaginal monthly contraceptive, Ovaprene's potential to be the first U.S. Food and Drug Administration (FDA)-approved hormone-free, monthly intravaginal contraceptive, the potential market opportunity for Ovaprene, if approved, and that enrollment in the ongoing pivotal Phase 3 clinical study of Ovaprene will be completed in 2026.
