London (UK), Rehovot (Israel), December 19th 2023 – Vidac Pharma Holdings Plc. (Hamburg and Stuttgart: T9G; ISIN:GB00BM9XQ619; WKN: A3DTUQ), a clinical-stage oncology biopharmaceutical company, has completed preparations for a Phase 2b trial of lead candidate VDA-1102 to treat actinic keratosis (AK). Today it announces that it has engaged a world-leading dermatology research institute, CentroDerm GmbH (Wuppertal, Germany), and mandated contract research organization Forschungsdock Gmbh to perform the study. Prof. Dr. Thomas Dirschka, one of the world’s pre-eminent experts in AK, will be the principal investigator of the study.
Cancer hijacks mitochondria to turn up the cellular metabolism, allowing cancer cells to proliferate, resist treatment and preventing programmed cell death. Vidac Pharma’s family of small molecules, including VDA-1102, modulate the HK2 protein, preventing it from blocking the VDAC channel, a signaling relay in mitochondria influencing cellular metabolism. They have been shown in preclinical and early clinical studies to be capable of reversing the abnormal metabolism of cancer cells, halting their hypergrowth. Vidac’s new approach may offer hope for better treatments in a wide range of types of cancer, as well as possibly in combination with available treatments.
“Non-melanoma skin cancers are the most-diagnosed cancers worldwide, and actinic keratosis is one of the most common among them. Treating AK can be tricky, because only 20% of the lesions it causes might become cancerous, yet it is essential to spot and treat the ones that do,” said Prof. Dirschka, and the founder of CentroDerm. “Currently available treatments are either not very effective, or cause unpleasant side effects that make them unattractive to patients and physicians. Vidac Pharma is now the first to perform a clinical trial into specifically this issue, with its VDA-1102 small molecule, which might offer the potential to significantly improve treatment.”
“This study has been designed and de-risked with the benefit of our positive Phase 2a and first Phase 2b trials,” said Prof. Dr. Max Herzberg, Chairman of the Board and Founder of Vidac Pharma. “We believe the trial will allow us to enter pivotal Phase 3 testing and are looking forward to initiating it once we have sufficient funding.”
The second Phase 2b study will focus on advanced AK only, to refine inclusion criteria and endpoints, after the earlier Phase 2b found higher sensitivity in advanced (e.g. proliferative) AK to VDA-1102 than less severe (e.g. non-cancerous) forms of the disease. A protocol will be finalized within two months and submitted to health authorities in Germany. Endpoints will include clearance of advanced AK lesions, and the evolution of lesions after a period of observation.

About Vidac Pharma
Vidac Pharma is a clinical-stage biopharmaceutical company dedicated to discovering and developing first-in-class medicines to help people suffering from a range of oncologic and onco-dermatologic diseases. Vidac develops first-in-class anti-cancer drugs by modifying the hyper glycolytic tumor microenvironment, targeting the overexpression and wrong anchoring of the Hexokinase 2 metabolic checkpoint (HK2) in cancer cells, to renormalize tumor microenvironment and selectively provoke their programmed death without affecting surrounding normal tissue. VDA-1102, a first drug candidate of Vidac Pharma was proven effective against advanced Actinic Keratosis (AK) and Cutaneous T-cell Lymphoma (CTCL) in Phase 2 trials in humans.
