02/12/2019 | 08:03am EDT
MIAMI, Feb. 12, 2019 (GLOBE NEWSWIRE) -- Veru Inc. (NASDAQ: VERU), an oncology and urology biopharmaceutical company developing novel medicines for the prostate cancer continuum of care and urology specialty pharmaceuticals, today announced that four presentations relating to Veru drug candidates are being given at the 2019 American Society of Clinical Oncology (ASCO) Genitourinary Cancers Symposium being held February 14-16, 2019 at the Moscone West Building in San Francisco, California.
Three of the presentations will be about VERU-111, our first-in-class selective oral alpha and beta tubulin inhibitor, which is in a Phase1b/Phase 2 clinical study in 5 clinical sites in the United States. The Phase 1b/2 addresses the large and growing unmet medical need to provide therapies for men who have metastatic castration resistant prostate cancer and who have also become resistant to novel androgen blocking agents (enzalutamide or abiraterone). There are currently no FDA approved drugs approved for this indication.
Presentation Number TPS330, Poster N6
Presentation Title: Design of Phase 1b/2 study of oral VERU-111, an α and β-tubulin inhibitor, for the treatment of metastatic castration and androgen blocking agent resistant prostate cancer. Presenter: Mark Markowski, MD, PhD, Assistant Professor of Oncology, The Johns Hopkins Sidney Kimmel Comprehensive Cancer Center Session Information: Poster Session A: Prostate Cancer Date/Time: February 14, 2019 – 11:30 AM – 1:00 PM and 5:30 PM – 6:30 PM
VERU-111 is currently enrolling an open label Phase1b/2 clinical study in men with metastatic castration prostate cancer who have also failed a novel androgen blocking agent (abiraterone or enzalutamide) and before intravenous taxane chemotherapy (prechemo). The study is being conducted in approximately 15 men in up to 5 clinical sites in the United States. The design of the Phase1b/2 study will be presented at the meeting. The Phase 1 portion will determine both the maximum tolerated dose (safety) and measure effectiveness by measuring serum PSA reductions in approximately 15 men using a standard 3+3 design. The open label Phase 2 clinical study component will enroll an additional 26 men evaluating the VERU-111 dose selected from the Phase 1b study. The primary efficacy endpoint will be the reduction in serum PSA and further assess safety.
Presentation Number 167, Poster G10
Presentation Title: VERU-111, a novel oral inhibitor of a and b tubulin, inhibits tumor growth in the human castration-resistant AR variant prostate cancer (PCa) model 22Rv1 Presenter: Mark Markowski, MD, PhD, Assistant Professor of Oncology, The Johns Hopkins Sidney Kimmel Comprehensive Cancer Center Session Information: Poster Session A: Prostate Cancer Date/Time: February 14, 2019 – 11:30 AM – 1:00 PM and 5:30 PM – 6:30 PM
In preclinical studies, oral doses of VERU-111 showed anti-tumor effectiveness in a highly aggressive animal model of human prostate cancer, 22Rv1. Human prostate cancer, 22Rv1 model is similar to the type of metastatic castration resistant prostate cancer affecting the patients enrolling in the Phase 1b/2 study as it is also resistant to androgen blocking agents (abiraterone and enzalutamide). In this preclinical study, oral VERU-111 treatment resulted in significant reductions in prostate cancer tumors and was well tolerated. In contrast, IV taxane chemotherapy with docetaxel did not significantly affect prostate cancer tumor growth and was not as well tolerated as the animals lost weight.
Presentation Number 299, Poster D7
Presentation Title: The oral a and b tubulin inhibitor, VERU-111, demonstrates no neutropenia, myelosuppression or abnormal liver function in doses being evaluated for the treatment of metastatic castration resistant prostate cancer in nonclinical toxicity studies. Presenter: Robert H. Getzenberg, PhD, Executive Associate Dean for Research and Professor of Medicine, Patel College of Medicine, Nova Southeastern University Session Information: Poster Session B: Prostate Cancer; Urothelial Carcinoma, Penile, Urethral, Testicular and Adrenal Cancers Date/Time: February 15, 2019 – 12:15 PM – 1:45 PM and 5:15 PM – 6:15 PM
Taxane chemotherapies, cabazitaxel and docetaxel, are given by intravenous administration once every 3 weeks, and neutropenia, drop in white blood cell count, is the dose limiting toxicity. VERU-111 was given orally each day for 28 days to assess its toxicity in both dogs and rats. VERU-111 was well tolerated and did not result in neutropenia in clinically relevant doses over the 28 days. As an orally administered drug, VERU-111 also did not have any significant changes in liver function tests and bilirubin levels. These safety studies support the possibility of daily dosing of VERU-111 in patients which may allow the oral delivery of more anticancer drug with potentially better safety profile than intravenous taxane chemotherapy.
Presentation Number TPS338, Poster Number N14
Presentation Title: A Phase 2, dose finding, placebo-controlled, study of zuclomiphene citrate to ameliorate the frequency and severity of hot flashes caused by androgen deprivation in men with advanced prostate cancer. Presenter: Robert H. Getzenberg, PhD, Executive Associate Dean for Research and Professor of Medicine, Patel College of Medicine, Nova Southeastern University Session Information: Poster Session A: Prostate Cancer Date/Time: February 14, 2019 – 11:30 AM – 1:00 PM and 5:30 PM – 6:30 PM
The clinical trial design of zuclomiphene citrate (VERU-944), a proprietary oral estrogen receptor agonist drug, will be presented. Zuclomiphene is being evaluated in a placebo controlled, randomized, dose finding (10mg, 50mg, and 100mg versus placebo), multicenter Phase 2 clinical study for the treatment of moderate to severe hot flashes caused by androgen deprivation therapy in men with advanced prostate cancer. Hot flashes are the most common major side effect of androgen deprivation therapy with drugs like LUPRON (leuprolide). Hot flashes not only adversely affect quality of life, but also cause men to consider stopping their cancer treatment for relief of these symptoms. A Phase 2 clinical trial is being conducted in 15 clinical sites in the United States. The primary endpoint is reduction in the frequency of moderate to severe hot flashes at 4 weeks and maintained at 12 weeks compared to baseline. There are no treatments that are FDA approved for this indication.
About VERU-111 VERU-111 is a novel, proprietary, next generation, first-in-class oral selective antitubulin agent that targets and disrupts alpha and beta tubulin subunits of microtubules. In cancer cells, microtubules are critical for transport of growth factor receptors, cellular proliferation, and metastases. In preclinical effectiveness and toxicity studies, orally administered VERU-111 demonstrated significant antitumor activity against castration and novel androgen blocking agent (abiraterone or enzalutamide) resistant human prostate cancers. Furthermore, VERU-111 had significant antitumor effects against cancers that overexpress multidrug resistant proteins, like P-glycoprotein, a common mechanism by which cancer cells become resistant to cancer drugs. At oral doses that had significant antitumor effects, VERU-111 had a favorable safety profile as it did not cause neutropenia or myelosuppression, common dose limiting side effects of other classes of commercially available antitubulins such as intravenous taxanes or intravenous vinca alkaloids.
Veru is conducting an open label Phase1b/2 clinical trial evaluating the safety and effectiveness of VERU-111 in men who have metastatic castration resistant prostate cancer who have also become resistant to novel androgen blocking agents like abiraterone or enzalutamide. In addition to prostate cancer, VERU-111 had antitumor effects in other cancer types including preclinical human models for triple negative breast cancer, ovarian cancer and pancreatic cancer. VERU-111 has the potential to be the first FDA approved selective antitubulin agent that targets and disrupts alpha and beta tubulin subunits of microtubules to treat cancer.
About Zuclomiphene Citrate Zuclomiphene citrate (VERU-944) is a novel, proprietary, oral, nonsteroidal, estrogen receptor agonist being evaluated in a Phase 2 clinical study to treat hot flashes, one of the most common side effects caused by androgen deprivation therapy (ADT), or hormone treatment for men with advanced prostate cancer. The Phase 2 clinical trial will enroll approximately 120 men in over 15 clinical sites in the United States. Zuclomiphene citrate has the potential to be the first FDA approved drug for hot flashes caused by prostate cancer hormone therapy. It is estimated that there are over 600,000 men in the US on ADT and about 30% of them suffer from moderate to severe hot flashes. Concern over hot flashes make men less likely to begin ADT and can lead to early discontinuation of this effective prostate cancer therapy. Based on an independent market analysis sponsored by the Company, the Company estimates the US market potential for zuclomiphene citrate is over $600 million annually.
About Veru Inc. Veru Inc. is an oncology and urology biopharmaceutical company developing novel specialty pharmaceuticals and medicines for the prostate cancer continuum of care. The Veru prostate cancer pipeline includes zuclomiphene citrate (also known as VERU-944, cis-clomiphene) and VERU-111 (bisindole). Zuclomiphene citrate is an estrogen receptor agonist being evaluated in a Phase 2 trial to treat hot flashes, a common side effect caused by hormone treatment for men with advanced prostate cancer. VERU-111 is an oral, next-generation, first-in-class selective small molecule that targets and disrupts alpha and beta subunits of microtubules in cells to treat metastatic prostate cancer patients whose disease is resistant to both castration and novel androgen blocking agent (abiraterone or enzalutamide) therapies. VERU-111 is being evaluated in men with metastatic refractory prostate cancer in an open label Phase 1b/2 clinical trial.
Veru is also advancing new drug formulations in its specialty pharmaceutical pipeline addressing unmet medical needs in urology. The clinical trial of the Company’s proprietary Tadalafil and Finasteride Combination tablet (TADFIN™ tablet) met FDA requirements for bioavailability and bioequivalence for the co-administration of tadalafil 5mg and finasteride 5mg dosed daily for benign prostatic hyperplasia (BPH). Tadalafil (CIALIS®) is currently approved for treatment of BPH and erectile dysfunction and finasteride (PROSCAR® and PROPECIA®) is currently approved for treatment BPH and male pattern hair loss. The co-administration of tadalafil and finasteride has been shown to be more effective for the treatment of BPH than either drug alone. The Company anticipates submitting an NDA for its TADFIN™ tablet under the 505(b)(2) regulatory pathway in the second half of calendar year 2019. Veru is also developing Tamsulosin DRS granules and Tamsulosin XR capsules which are formulations of tamsulosin, the active ingredient in FLOMAX®, which Veru has designed to avoid the “food effect” inherent in currently marketed formulations of the drug, allowing for potentially safer administration and improved patient compliance (NDA submission expected in 2019).
