Veru Enrolls First Patient in International Phase 3 ARTEST Clinical Trial of Enobosarm in Metastatic Breast Cancer
Veru Inc. (NASDAQ: VERU) has initiated the Phase 3 ARTEST trial, enrolling its first patient for enobosarm, a targeted hormone therapy for AR+ER+HER2- metastatic breast cancer. This trial, conducted across 49 sites in the U.S. and Europe, aims to evaluate the efficacy and safety of enobosarm versus active controls for patients previously treated with estrogen blockers and CDK4/6 inhibitors. A companion diagnostic test will be developed to identify the most suitable candidates. The study targets around 210 patients and aims to address a significant unmet need in breast cancer treatment.
- Initiation of Phase 3 ARTEST trial for enobosarm targeting metastatic breast cancer.
- Enobosarm showed a clinically meaningful benefit rate of 32% and 29% in Phase 2 study cohorts.
- A companion diagnostic will enhance patient selection for treatment.
- Trial results are uncertain; future efficacy and safety outcomes remain to be seen.
- Potential competition and market acceptance risks could impact product success.

MIAMI, Oct. 13, 2021 (GLOBE NEWSWIRE) -- Veru Inc. (NASDAQ: VERU), an oncology biopharmaceutical company with a focus on developing novel medicines for the management of prostate and breast cancer, today announced that it has enrolled the first patient in its Phase 3 ARTEST registration trial of enobosarm, an oral selective androgen receptor (AR) targeting agonist, for patients with AR+ER+HER2- metastatic breast cancer who had tumor progression following treatment with estrogen blocking agents and CDK4/6 inhibitors.
“While endocrine therapies have been the mainstay of breast cancer treatment for decades, these therapies have all focused on the estrogen receptor. Targeting the AR, a demonstrated tumor suppressor, provides us with an opportunity to bring a truly novel hormone treatment approach to patients who have AR+ER+HER2- metastatic breast cancer,” said Mitchell Steiner, M.D., Chairman, President and Chief Executive Officer of Veru Inc. “We already have substantial safety information about enobosarm therapy as it has been evaluated in 25 clinical trials comprising over 2,000 patients with approximately 350 patients dosed at 9mg or higher doses. Enobosarm is well tolerated and has also resulted in improvements in quality of life including reported better physical function, mobility, and pain in metastatic breast cancer patients. Furthermore, a recent Phase 2 study in heavily pretreated patients with metastatic breast cancer confirmed that enobosarm’s efficacy was best in women that had
“Targeting patients expressing the androgen receptor allows us to focus a new endocrine approach on patients that have become resistant to existing therapies,” said Adam Brufsky, M.D., Ph.D., Professor of Medicine, Associate Chief, Division of Hematology/Oncology and Co-Director, Comprehensive Breast Cancer Center at the University of Pittsburgh Medical Center. Dr. Brufsky is also the Principal Investigator of the ARTEST study. “I couldn’t be more pleased that Veru is advancing enobosarm into a registration Phase 3 trial for the treatment of hormone receptor positive metastatic breast cancer in an effort to fill an unmet medical need benefitting these patients.”
ARTEST Phase 3 Trial Design
The Phase 3 ARTEST (Androgen Receptor Targeting Agent, Enobosarm, for the Treatment of Metastatic ER+ Breast Cancer) clinical trial is an international, multicenter, open-label randomized, active control pivotal study evaluating the efficacy and safety of enobosarm 9mg oral daily dosing versus active control (exemestane +/- everolimus or SERM – physician’s choice) in the 3rd line metastatic treatment of approximately 210 metastatic AR+ ER+ HER2- advanced breast cancer patients who had tumor progression on a nonsteroidal aromatase inhibitor (anastrozole or letrozole), fulvestrant, and a CDK4/6 inhibitor. Enobosarm is being targeted to patients with positive androgen receptor staining using a threshold of ≥
About the Enobosarm Phase 2 (G200802) Study
The Phase 2 clinical study was an open label, parallel design, randomized study to investigate the efficacy and safety of enobosarm 9mg and 18mg oral daily dosing in 136 heavily pretreated women with ER+ HER2- metastatic breast cancer who had breast cancer progression being treated with multiple lines of endocrine therapy and
The Phase 2 primary endpoint demonstrated clinically meaningful clinical benefit rate of
Women being treated with 9mg or 18mg of enobosarm also reported significant improvements in quality-of-life measurements including mobility, anxiety/depression and pain discomfort. Overall, enobosarm was well tolerated with most of the observed adverse events being grade 1 and 2. Drug related severe adverse events (SAEs) (Grades 3-4) were observed in 6 patients (
Enobosarm Clinical Development Program
Enobosarm is in clinical development for two indications: (i) a Phase 3 ARTEST clinical study evaluating enobosarm for the treatment of 3rd line metastatic AR+ER+HER2- breast cancer patients whose disease has progressed after treatment with a nonsteroidal aromatase inhibitor, fulvestrant, and a CDK4/6 inhibitor which is enrolling; and (ii) a Phase 3 ENABLAR-2 clinical study evaluating enobosarm + abemaciclib combination therapy as treatment of 2nd line metastatic AR+ER+HER2- breast cancer patients whose breast cancer has progressed after treatment with palbociclib and either a nonsteroidal aromatase inhibitor or fulvestrant combination. The Phase 3 ENABLAR-2 clinical trial is expected to begin enrollment in calendar Q4 2021.

Veru’s prostate cancer pipeline includes: sabizabulin, an oral, first-in-class, new chemical entity that targets the cytoskeleton which in prostate cancer also disrupts the transport of the androgen receptor. A Phase 3 VERACITY clinical trial evaluating the efficacy and safety of sabizabulin in approximately 245 men for the treatment of metastatic castration and androgen receptor targeting agent resistant prostate cancer is enrolling. VERU-100, a novel, proprietary gonadotropin releasing hormone antagonist peptide long acting 3-month subcutaneous injection formulation for androgen deprivation therapy to treat hormone sensitive advanced prostate cancer, is currently enrolling in a dose finding Phase 2 clinical trial, and the Phase 3 clinical trial is planned to initiate in calendar Q4 2021. Veru’s breast cancer pipeline includes: enobosarm, an oral, first-in-class, new chemical entity, selective androgen receptor agonist that targets the androgen receptor, a tumor suppressor, to treat AR+ER+HER2- metastatic breast cancer without unwanted masculinizing side effects. The enobosarm clinical program is initially focusing on 2 indications: 1) Phase 3 ARTEST clinical trial to evaluate enobosarm monotherapy in a 3rd line metastatic setting in approximately 210 subjects with AR+ER+HER2- metastatic breast cancer (≥
