Exhibit 99.1

Daré Bioscience, Inc. Announces Initiation of Content Validity Study for Sildenafil Cream, 3.6%, a Potential Therapy for Female Sexual Arousal Disorder

Sildenafil Cream, 3.6% has the Potential to Receive the First FDA Approval for Female Sexual Arousal Disorder

SAN DIEGO, Nov. 29, 2018 (GLOBE NEWSWIRE) — Daré Bioscience, Inc. (NASDAQ: DARE), a leader in clinical-stage women’s health innovation, and Strategic Science & Technologies, LLC (SST), a Cambridge, MA based novel topical drug delivery company, today announced the initiation of a content validity study intended to support the use of specific patient reported outcome (PRO) measures to assess efficacy in female sexual arousal disorder (FSAD) patients in the Phase 2b and Phase 3 program for Sildenafil Cream, 3.6%.

This non-interventional study is designed to explore the experience of FSAD and evaluate the relevance of the selected PRO measures based on patients’ own experiences and determine patients’ understanding of the items, instructions, and response options of the selected PRO measures. Subjects that meet the inclusion criteria will participate in one-on-one, in-depth interviews conducted by subject matter experts in the field of clinical outcome assessments and female sexual medicine, which include thought leaders in the field of sexual medicine that are a subset of the sites that are expected to enroll subjects into the Phase 2b at-home interventional study. This non-interventional content validity study provides a unique opportunity to pilot the methods intended to be used, subject to U.S. Food and Drug Administration (FDA) approval, to identify, screen and diagnose women with FSAD in the Phase 2b at-home interventional study.

“We’re excited to announce that we have reached this milestone with the initiation of the content validity study for our Sildenafil Cream, 3.6% program,” said Sabrina Martucci Johnson, President and CEO of Daré Bioscience. “Although numerous pharmaceutical products have been developed, tested and approved to treat erectile dysfunction (ED) in men, women continue to lack effective options for FSAD, an analogous condition. Sildenafil is marketed in an oral dosage form under the brand name Viagra^® for the treatment of ED in men, and we plan to leverage the existing data and safety profile of the Viagra^® brand for our Sildenafil Cream, 3.6% program. Correct selection and implementation of a validated PRO to assess efficacy is a critical component of our successful Phase 2b and Phase 3 program. The goal of the study is to demonstrate that women both understand the PRO items and agree that they capture their most important and relevant symptoms and impacts of FSAD. We believe that establishing a content valid and well-understood PRO tool will help us provide confidence in the efficacy endpoints selected for the Phase 2b study.”

Sildenafil Cream, 3.6% is a proprietary cream formulation specifically designed to increase blood flow to the genital tissue in women, leading to a potential improvement in genital arousal response during sexual activity. If successful, Sildenafil Cream, 3.6% has the potential to be the first FDA-approved FSAD treatment option.

“The content validation study is part of a robust clinical development program designed to support this innovative application of sildenafil for the treatment of FSAD,” said Steven Brugger, President and Chief Operating Officer of SST. “Working in concert with the FDA we look forward to advancing the program towards important near-term value inflection milestones in the Phase 2b program, beginning with the content validity study.”

About FSAD

Unlike other female sexual disorders, FSAD is characterized primarily by an inability to attain or maintain sufficient physical sexual arousal that causes distress or interpersonal difficulty. It is the closest analog in women to ED in men. While increased attention has been focused on female sexual dysfunction over the past several years, no pharmacologic options have yet been FDA approved for FSAD. In a Phase 2a trial, Sildenafil Cream, 3.6% increased measurable blood flow to the vaginal tissue in both pre- and postmenopausal women with FSAD compared to placebo.
