Clinigen Group Partners with Sunesis to Initiate a Compassionate Use Program for Patients with Relapsed or Refractory Acute Myeloid Leukemia

Clinigen Group plc's (AIM: CLIN, 'Clinigen' or the 'Group') Managed Access (MA) division has partnered with Sunesis Pharmaceuticals, Inc. (NASDAQ:SNSS) to manage its compassionate use program for vosaroxin. The program has been initiated today and will be made available to eligible patients in the U.S. and selected European countries diagnosed with relapsed or refractory acute myeloid leukemia (AML).

Vosaroxin is an investigational treatment and is currently not approved for use by any regulatory agency. Compassionate use programs are put in place to provide access to medicines for patients who have serious, or immediately life-threatening illnesses, and for whom no alternative treatment options are available. Access is provided in response to an unsolicited request from a physician for his/her patient with an unmet medical need.

Simon Estcourt, Managing Director of Idis Managed Access, Clinigen Group said: "AML is the most common acute leukemia affecting adults, with a very low survival rate, so there is a real need for new treatment options in these patients. By using our global logistical and regulatory expertise we will work with Sunesis and the AML community to provide ethical access to vosaroxin to help eligible patients who have no alternative treatment options."

"Sunesis is committed to providing patients and healthcare providers around the globe with more options for treating relapsed and refractory AML, a disease for which the standard of care has changed little in the last four decades," said Par S Hyare, VP Global Oncology Operations, Sunesis. "We are pleased to be working with Idis MA, a recognized leader in providing ethical access to medicines that address unmet needs and will be working towards gaining approval for vosaroxin in the U.S. and Europe for the treatment of relapsed and refractory AML."

About vosaroxin

Vosaroxin is an anti-cancer quinolone derivative (ADQ) under investigation for the treatment of AML. Vosaroxin intercalates DNA and inhibits topoisomerase II, causing replication-dependant, site-selective DNA damage, G2 arrest and apoptosis. Both the U.S. Food and Drug Administration (FDA) and European Commission granted orphan drug designation to vosaroxin for the treatment of AML. Additionally, vosaroxin has been granted fast track designation for potential treatment of relapsed or refractory AML in combination with cytarabine. Vosaroxin is an investigational medicine and has not been approved for use by any regulatory agency.
