BASEL, Switzerland, May 31, 2016 /PRNewswire/ —
Mundipharma EDO GmbH (Early Development in Oncology) has announced the initiation of a first-in-human clinical trial of its investigational drug candidate EDO-S101. A first in class, fusion molecule – S101 is currently being developed for the treatment of relapsed-refractory (RR) haematological malignances. This phase 1 study is designed to evaluate the safety and tolerability of ascending doses of EDO-S101 and will be conducted at several sites across the United States and Europe.

EDO-S101 is the first representative of the A-DAC principle, a new approach in chemotherapy that uses fusion technology to combine an alkylating agent with a pan-histone deacetylase inhibitor (HDAC) to simultaneously damage DNA and block damage repair. The combination of the two different modes of action has the potential to overcome resistance towards other conventional chemotherapies. EDO-S101 combines the active structures of bendamustine and vorinostat, two molecules that have been well established in the treatment of haematological malignancies, to produce a novel single agent with efficacy characteristics superior to those of the parent compounds given in combination.[1],[2]
Dr. Thomas Mehrling, CEO, Mundipharma EDO GmbH commented: “Today EDO forges ahead with even greater momentum following this important milestone of a first-in-human trial. EDO-S101 is making significant progress in its clinical development journey and we are passionate about its potential to treat patients with relapsed-refractory haematological malignances, who are in dire need of new treatment options. The primary goal of this first clinical trial is to evaluate the safety and tolerability of EDO-S101 and its pharmacokinetic profile. These data will be used to establish the recommended dose which will then be further evaluated for safety and efficacy.”
Preclinical experiments demonstrated that EDO-S101 exerts significant activity against haematological malignancies including multiple myeloma (MM)[1],[3], acute myeloid leukemia (AML)[1],[4], mantle cell lymphoma (MCL)[2], ABC type diffuse large B-Cell lymphoma (DLBCL)[3] as well as hodgkin lymphoma (HL)[3]. In addition, the molecule is active in primary resistant cells as well as in cells that have acquired resistance.[5]

About the study
The Phase 1 multi-centre, clinical trial will assess the safety and tolerability of EDO-S101 administered intravenously once in a 28-day cycle. The study will enroll patients with relapsed refractory haematological malignancies for which there are no available therapies and it is designed as a two stage trial. The key objectives of stage one are to determine a maximum tolerated dose and pharmacokinetic profile, while in stage two the recommended dose will be further evaluated for safety and preliminary anti-tumor activity in selected haematological malignancies. Please refer to http://www.clinicaltrials.gov for additional clinical trial details.
About relapsed refractory haematological malignancies
Despite recent improvements in the treatments of haematological malignancies, patients who have relapsed or refractory disease remain a clinical challenge due to limited effective treatment options.
For example, almost all patients with MM who survive initial treatment will eventually relapse and will require further therapy. The patient survival rate for MM up to five years is 48.5%.[6]
Relapse in HL occurs in a small proportion of patients; approximately 5% to 8% of those presenting with limited stage disease and 15% to 20% of those with advanced stage disease.[7]
In the majority of patients with AML who achieve a complete remission (CR), the leukaemia will recur within 3 years. In general, the prognosis of patients after relapse is poor and treatment options unsatisfactory.[8]
