Vaderis Therapeutics AG announces Initiation of Clinical PoC trial in HHT

Nicholas Benedict, CEO of Vaderis

Vaderis Therapeutics AG (Vaderis), one of the clinical stage biotechnology company focused on developing treatments for rare diseases associated with vascular malformations, recently announced its emergence from stealth and initiation of its INSIGHT proof-of-concept (PoC) clinical trial in patients suffering from Hereditary Haemorrhagic Telangiectasia (HHT), also known as Osler-Weber-Rendu Syndrome. Vaderis was established in 2019 and in 2020 raised over CHF18 million from Medicxi, enabling progression of its lead asset into the clinic and successful completion of Phase 1a.

Emergence from Stealth Vaderis was founded with the unique aim to develop therapeutics for rare and orphan diseases associated with vascular malformations.  In April 2020 Vaderis acquired a portfolio of allosteric AKT inhibitors from Almac Discovery Ltd of Belfast, UK.  AKT is a serine kinase which plays a crucial role in vascular growth and in vascular overgrowth.  There is a significant number of rare diseases such as HHT in which upstream genetic mutations trigger over-activation of the serine kinase AKT, resulting in vascular overgrowth.  Such diseases frequently manifest in ways that are debilitating, disfiguring, painful and sometimes life-threatening.  The vast majority of these diseases are currently left untreated except for symptomatic interventions which tend to offer patients limited temporary relief of individual symptoms. VAD044 is a once daily, orally administered, allosteric AKT inhibitor which has the potential to treat the underlying cause of these diseases.  If successful, Vaderis would be the first company in the world to develop a medicine for the treatment of HHT and other diseases associated with vascular malformations.

Initiation of Clinical PoC in HHT In pursuit of the company’s core objective, Vaderis announces the initiation of the first study of VAD044 in HHT patients. Known as the INSIGHT proof-of-concept trial (INternational Study InvestiGating HHT), the study is unique in its robust design aimed at achieving a thorough understanding of the safety of VAD044 in HHT patients. A total of 80 HHT patients across the USA, Canada and Europe will be randomised in a double-blind, controlled trial comparing two doses of VAD044 to placebo.  Initiation of the INSIGHT trial follows Health Authority approvals including FDA, Health Canada and key European agencies.

J.J. Mager, MD, PhD, pulmonologist at St. Antonius Hospital Utrecht, Chairman of the Global Research and Medical Advisory Board of Cure HHT and lead investigator of the INSIGHT trial commented, “The first patients recruited into the INSIGHT trial mark an exciting milestone in HHT clinical research.  If successful, this trial may demonstrate the potential of this new drug to be effective beyond the symptomatic treatments we currently offer HHT patients, by addressing the course of this rare, progressive, and debilitating disease.”

Nicholas Benedict, CEO of Vaderis added, “Working together with the HHT community, both caregivers and patient associations, Vaderis hopes to be the catalyst which transforms patient care in HHT.  Success in the INSIGHT trial would be a major step towards developing the first ever registered treatment for HHT anywhere in the world.”

Giovanni Mariggi, Partner at Medicxi and Chairman of Vaderis

Giovanni Mariggi, Partner at Medicxi and Chairman of Vaderis said, “Our vision is to create a unique company dedicated to delivering breakthrough therapies for rare diseases caused by vascular malformations. Initiation of the INSIGHT trial is an important milestone on the way to realising this vision.  It is testament to the significant progress made by the company over the last two years”.
