ACTiON Study : Chemotherapy Induced Peripheral Neuropathy (CIPN)
ACTiON is a Phase 2, double blind placebo-controlled crossover randomised clinical trial (‘RCT’) to assess Ananda’s patent-pending MRX1 drug candidate versus placebo in the treatment of CIPN.

About CIPN and its treatment
- CIPN is one of the most frequent side effects of treatment of cancers with chemotherapy, affecting up to 50% of patients.
- There are 160,000 new patients every year in the UK alone.
- CIPN has a ‘glove and stocking’ distribution and symptoms include pins and needles, tingling, pain, burning, hyperalgesia (increased response to normally painful stimulus), allodynia (pain in response to innocuous stimulus), proprioception difficulties, functional impairment, fine motor task difficulties, Quality of Life impairment.
- Currently there are no effective treatments for the prevention of CIPN and symptomatic treatment is frequently ineffective. It is a condition with a high unmet clinical need.
