Alpha Tau Seeks to Revolutionize Skin Cancer Treatment Options

Alpha Tau Secures FDA Approval for Pivotal Study

Alpha Tau Medical Ltd. (NASDAQ: DRTS, DRTSW), an innovative leader in cancer therapeutics, has received a significant breakthrough with the FDA's recent approval of an Investigational Device Exemption (IDE). This allows Alpha Tau to commence a multi-center study focused on treating recurrent cutaneous Squamous Cell Carcinoma (cSCC) in immunocompromised patients using their advanced Alpha DaRT therapy.

The Importance of the Clinical Study

Initiated by the Winship Cancer Institute of Emory University in Atlanta, this clinical study aims to enroll a total of 28 patients across eight U.S.-based institutions. It targets individuals with recurrent cSCC, specifically those facing challenges due to immunosuppression from primary or secondary immunodeficiencies, thereby excluding diabetes. The primary goal is to evaluate the objective response rate (ORR) to the Alpha DaRT treatment, while secondary goals encompass progression-free and overall survival rates, along with local control metrics tracked for a period of twelve months after treatment.

Understanding cSCC and Immunocompromised Risks

The rising incidence of non-melanoma skin cancers, particularly cSCC, among organ transplant recipients is alarming. Research showcased in the Journal of Clinical Medicine underscores that these patients face a staggering 65 to 100 times higher risk of developing cSCC compared to their non-transplant counterparts. Furthermore, a notable study from the New England Journal of Medicine revealed that a majority—over 50%—of Caucasian organ transplant recipients are likely to face a diagnosis of cutaneous carcinomas.

Clinical Insights from Leading Experts

Dr. Zachary Buchwald, a key figure in the trial as the Principal Investigator from Winship, expressed enthusiasm regarding the commencement of this pioneering research. He noted the imperative need to address treatment gaps for immunocompromised patients using Alpha DaRT, especially as the earlier ReSTART trial has shown promising results.

Alpha Tau’s CEO, Uzi Sofer, emphasized the partnership with Emory University, sharing how the clinical community's growing interest in treating immunocompromised individuals has led to this new study. The potential to offer an impactful treatment alternative for these vulnerable patients stands at the forefront of Alpha Tau’s mission.

Behind the Science of Alpha DaRT

Alpha DaRT, or Diffusing Alpha-emitters Radiation Therapy, represents a groundbreaking approach that facilitates exceptionally potent and highly targeted alpha-radiation delivery to solid tumors. This innovative therapy leverages intratumoral delivery of radium-224 sources that, upon decay, release high-energy alpha particles. This targeted strategy is designed to destroy malignant cells while sparing surrounding healthy tissues, a crucial aspect for patient outcomes.

The Path Ahead for Alpha Tau

Founded in 2016, Alpha Tau has rapidly positioned itself as a key player in oncology therapeutics, dedicated to the development and commercialization of the Alpha DaRT technology for solid tumor management. With its roots tied to pioneering work from notable researchers at Tel Aviv University, the company’s vision resonates with both scientific advancement and patient care.

Dr. Robert B. Den, Chief Medical Officer of Alpha Tau, highlighted the trial's significance, focusing on a particularly vulnerable patient demographic. As treatment options remain limited for these individuals, the anticipated clinical trial outcomes are expected to bring forth new hope and alternatives.
