The Company has Completed a Positive Phase 3 COVID-19 Study in Hospitalized Moderate to Severe COVID-19 Patients at High Risk for ARDS.
A double-blind, randomized, placebo-controlled Phase 3 COVID-19 clinical trial was conducted in approximately 210 hospitalized COVID-19 patients with moderate to severe COVID (≥ WHO 4-supplemental oxygen) at high risk for ARDS and death. The primary endpoint was the proportion of deaths by Day 60. Based on a planned interim analysis of the first 150 patients randomized, the Independent Data Monitoring Committee unanimously halted the study for overwhelming efficacy and safety. Treatment with sabizabulin 9mg once daily, an oral, first-in-class, new chemical entity, microtubule disruptor that has dual anti-inflammatory and antiviral properties, resulted in a clinically meaningful and statistically significant 55.2% relative reduction in deaths.
On June 6, 2022, the Company submitted a request for emergency use authorization to FDA. On July 6, 2022, the Company announced the publication of the Phase 3 COVID-19 trial results evaluating the efficacy and safety of oral sabizabulin in The New England Journal of Medicine Evidence®. On July 25, 2022, the UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) informed the Company that the sabizabulin marketing authorization application will receive expedited review. On July 27, 2022, the European Medicines Agency’s Emergency Task Force initiated the review of sabizabulin treatment for hospitalized COVID-19 patients for emergency use in European Union countries.
The Company has scaled up manufacturing processes and will be able to produce commercial drug supply to address anticipated drug needs following potential FDA authorization and subsequent authorizations in the U.S. as well as other countries and regions.
The Company has initiated discussions with government agencies to discuss potential government purchases of sabizabulin in the U.S. and other countries around the world.

Enobosarm, a Novel Oral Selective Androgen Receptor Targeting Agonist, for the 3rd Line Treatment of AR+ ER+ HER2- Metastatic Breast Cancer with AR ≥ 40% Expression—Phase 3 ARTEST Clinical Study- Enrolling.
Enobosarm is an oral, new chemical entity, selective androgen receptor targeting agonist that activates the androgen receptor (AR), a tumor suppressor, in AR+ER+HER2- metastatic breast cancer without causing unwanted masculinizing side effects. Enobosarm has extensive nonclinical and clinical experience having been evaluated in 25 separate clinical studies in approximately 1,450 subjects dosed, including three Phase 2 clinical studies in advanced metastatic breast cancer involving more than 250 patients. In the two Phase 2 clinical studies conducted in women with AR+ER+HER2- metastatic breast cancer, enobosarm demonstrated significant antitumor efficacy in heavily pretreated cohorts that previously failed estrogen receptor blocking agents, chemotherapy, and/or CDK 4/6 inhibitors and enobosarm was well tolerated with a favorable safety profile.
We are enrolling the Phase 3 multicenter, international, open label, and randomized (1:1) ARTEST registration clinical trial design to evaluate enobosarm monotherapy versus physician’s choice of either exemestane ☐ everolimus or a selective estrogen receptor modulator (SERM) as the active comparator for the treatment of AR+ ER+ HER2- metastatic breast cancer in approximately 210 patients with AR expression ≥40% in their breast cancer tissue who had previously received a nonsteroidal aromatase inhibitor, fulvestrant, and a CDK4/6 inhibitor. In January 2022, the FDA granted Fast Track designation to the ARTEST Phase 3 registration program, a distinction that underscores the urgent need for novel, targeted therapies for this important unmet medical need.
