Powering Vision with Science, Together

Science Over Cancer

Vivacitas Oncology, Inc. is developing next-generation technology coupled with proprietary synthesis methods to serve patients with particularly challenging prognoses.

Our lead development candidate (AR-67) is a novel lipophilic compound demonstrating high blood stability, targeting improved efficacy and tolerability.

Other development candidates include Rubitecan (Orathecin), a 2nd generation, semi-synthetic Camptothecin with potential for oral delivery.

Our team of top scientists is breaking new ground on cancer treatment options for patients through scientific discovery.

  • Next-Generation Camptothecin to improve efficacy and tolerability
  • Well understood target and mechanism of action
  • Proprietary synthesis
  • Unique, Patient-Focused Innovation
  • Orphan Drug Designation for Glioblastoma Multiforme

We are pioneering new synthesis methods to give patients and their families new alternatives in the fight against aggressive cancers

  • Proprietary Synthesis Method
  • Results Backed by Scientific Data
  • Unique lipophilic molecular design

Please look at what is best placed in our science, which is the unique design of our lipophilic molecule, and what is best in our technology, which is the proprietary synthesis method
