Pinpoint Therapeutics is developing novel cancer treatment options aimed to specifically inhibit autophagy, a key cell survival and treatment resistance pathway in cancer. Pinpoint inhibitors target a recently discovered enzyme in the autophagy pathway called PPT1, which is highly expressed across most cancers. These inhibitors could be applied to a broad range of cancers alone or in combination to overcome therapy resistance. Further development of these compounds towards clinical drug candidates will be undertaken by Pinpoint Therapeutics to determine the clinical utility of this novel treatment strategy.
Joining Pinpoint in 2019, Christian brings with him 28+ years of successful scientific, clinical, development and commercialization experience in both academia and the pharmaceutical industry, including CSL Behring, J&J spinoff Therakos and start-up Realm Therapeutics. Instrumental in obtaining FDA approval for seven products.
