Theriva Biologics Announces Orphan Medicinal Product Designation Granted by the European Commission to VCN-01 for the Treatment of Retinoblastoma
“We are very pleased with the European Commission's grant of orphan medicinal product designation to VCN-01, emphasizing the urgent need for new treatment options for retinoblastoma,” said Steven A. Shallcross, Chief Executive Officer of Theriva Biologics. “We have previously reported encouraging results from an investigator sponsored Phase 1 trial evaluating the safety and activity of intravitreal VCN-01 in pediatric patients with refractory retinoblastoma, and we are working closely with leading physicians and regulatory agencies worldwide to refine our clinical strategy for VCN-01 as an adjunct to chemotherapy in children with this challenging disease.”
The EMA recommends orphan designation for products intended to treat, prevent or diagnose a disease that is life-threatening or chronically debilitating and either the prevalence of the condition in the European Union (EU) does not exceed 5 in 10,000 or it is unlikely that marketing of the product would generate sufficient returns to justify the investment needed for its development. Additionally, there should be no authorizable method of diagnosis, prevention or treatment of the condition, or, if such a method exists, the medicine must be of significant benefit to those affected by the condition. Orphan designation is designed to provide drug developers with various benefits to support the development of novel therapies, including 10-years of market exclusivity once they receive marketing authorization in the EU, protocol assistance, administrative and procedural assistance, and reduced fees for regulatory activities.
About Retinoblastoma
Retinoblastoma is a tumor that originates in the retina and is the most common type of eye cancer in children. It occurs in approximately 1/14,000 - 1/18,000 live newborns and accounts for 15% of the tumors in the pediatric population < 1 year old. The average age of pediatric patients at diagnosis is 2, and it rarely occurs in children older than 6. In Europe, retinoblastoma has an estimated incidence rate of 1 per 13,844 live births (14.1 per million children under the age of 5) with approximately 300 children diagnosed per year ( Stacey et al. 2021 ). Preserving life and preventing the loss of an eye, blindness and other serious effects of treatment that reduce the patient's life span or the quality of life, remains a challenge. In addition, children with retinoblastoma have been more likely to lose their eye and die of metastatic disease in low-resource countries.
About VCN-01
VCN-01 is a systemically administered oncolytic adenovirus designed to selectively and aggressively replicate within tumor cells and degrade the tumor stroma that serves as a significant physical and immunosuppressive barrier to cancer treatment. This unique mode-of-action enables VCN-01 to exert multiple antitumor effects by (i) selectively infecting and lysing tumor cells; (ii) enhancing the access and perfusion of co-administered chemotherapy products; and (iii) increasing tumor immunogenicity and exposing the tumor to the patient's immune system and co-administered immunotherapy products. Systemic administration enables VCN-01 to exert its actions on both the primary tumor and metastases. VCN-01 has been administered to over 140 patients to date in clinical trials of different cancers, including PDAC (in combination with chemotherapy), head and neck squamous cell carcinoma (with an immune checkpoint inhibitor), ovarian cancer (with CAR-T cell therapy), colorectal cancer, and retinoblastoma (by intravitreal injection). More information on these clinical trials is available at Clinicaltrials.gov.
About Theriva Biologics, Inc.
Theriva Biologics (NYSE American: TOVX), is a diversified clinical-stage company developing therapeutics designed to treat cancer and related diseases in areas of high unmet need. The Company's wholly-owned Spanish subsidiary Theriva Biologics, S.L., has been developing a new oncolytic adenovirus platform designed for intravenous (IV), intravitreal and antitumoral delivery to trigger tumor cell death, improve access of co-administered cancer therapies to the tumor, and promote a robust and sustained anti-tumor response by the patient's immune system. In addition to VCN-01, the Company's clinical-stage candidates include (1) SYN-004 (ribaxamase) which is designed to degrade certain commonly used IV beta-lactam antibiotics within the gastrointestinal (GI) tract to prevent microbiome damage, thereby limiting overgrowth of pathogenic organisms such as VRE (vancomycin resistant Enterococci) and reducing the incidence and severity of acute graft-versus-host-disease (aGVHD) in allogeneic hematopoietic cell transplant (HCT) recipients); and (2) SYN-020, a recombinant oral formulation of the enzyme intestinal alkaline phosphatase (IAP) produced under cGMP conditions and intended to treat both local GI and systemic diseases.
