Aditum Bio, Co-Founded by Novartis Veterans Joe Jimenez and Dr. Mark Fishman, forms Second Company

Tempero Bio to develop drug candidate aimed at treating neurological diseases

Oakland California, November 2, 2020 [NEWSWIRE] – Aditum Bio, the biotech investment firm cofounded in 2019 by former Novartis CEO Joe Jimenez and former President of the Novartis Institutes for BioMedical Research (NIBR) Dr. Mark Fishman, today announced the formation of Tempero Bio, a portfolio company developing a new neuroscience drug for the treatment of substance use disorders and anxiety, often neglected fields in drug development, to help address significant treatment gaps for patients. Tempero Bio is being formed in partnership with Sosei Heptares, the Japan-listed biopharmaceutical company, from which the drug, TMP-301, was in-licensed.

Tempero Bio is the second independent company launched by Aditum Bio, whose mission is to give large patient populations access to medicines which otherwise may not be developed. To speed these drugs to market, Aditum Bio utilizes a Silicon Valley-inspired model, creating an individual “spin-out” company to implement Phase I and Phase II clinical trials. The “spin-out” structure enables a nimble, start-up culture with its own dedicated team of managers. “Our goal is to take drug candidates with enormous potential and accelerate those drugs through Phase II, helping to bring life changing treatments to patients in need more quickly,” said Joe Jimenez, Co-Founder and Managing Director of Aditum Bio. Dr. Mark Fishman, Co-Founder and Chair of the Medical and Scientific Advisory Boards added, “By focusing Aditum Bio on the translational medicine phase of drug development, we are able to rapidly move pre-clinical candidates into human trials, to get an early read on their safety and efficacy.”

Aditum Bio uses data, software and technology to help bring innovative medicines through the clinical trial phase. The company has partnered with TrialSpark, a technology driven research company that can complete clinical trials faster and at a lower cost than traditional trials. TrialSpark partners with doctors to create trial sites within their existing practices. Their digital platform enables faster patient recruitment, together with common data entry and analysis across sites which leads to speed, quality, and standardization.

Aditum Bio is taking a new approach to healthcare: one which combines behavior modification with the pharmaceuticals to create a better patient outcome. Each therapeutic will be supported by a digital device such as a mobile app, which engages with the patient to help them through their treatment journey. This allows scalable patient support enabled by technology, and can help improve key treatment challenges such as adherence.

Anxiety and addiction rates have both increased since the onset of the COVID-19 pandemic, with the Center for Disease Control (CDC) reporting that Americans are now 3 time more likely to report anxiety symptoms than in 2019, and that many Americans are consuming more alcohol or drugs due to the pandemic. TMP-301 is a mGluR5 negative allosteric modulator (NAM). Research has shown that metabotropic glutamate receptors (mGlurs) play a substantial role in numerous central nervous system diseases and psychiatric disorders by helping to control glutamate activity in the brain.
