FDA agreed that the Phase 3 COVID-19 study is sufficient to support the efficacy portion of a request for EUA submission and for an NDA submission.
FDA also agreed that the current safety data available for sabizabulin is sufficient to support the safety portion of a request for EUA submission. FDA informed the Company that additional safety data that would be collected during the use of sabizabulin under the EUA, if granted, will be sufficient to support an NDA submission, and furthermore, that no additional safety clinical studies are required.
The Company plans to submit a request for an EUA application in calendar 2Q 2022.
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 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.
Enobosarm and Abemaciclib, CDK 4/6 Inhibitor, Combination Therapy for the 2nd Line Treatment of AR+ER+HER2- Metastatic Breast Cancer with AR ≥ 40% Expression - Phase 3 ENABLAR-2 Clinical Study-Enrolling.
We are enrolling the Phase 3 multicenter, open label, randomized (1:1), active control clinical study, named ENABLAR-2 to evaluate the treatment of the enobosarm and abemaciclib combination versus an alternative estrogen blocking agent (fulvestrant or an aromatase inhibitor) in subjects with AR+ ER+
