- The test design has been improved for a better assessment of DNV3837 effectiveness in treating Clostridium difficile infections,
- This will be a multicenter trial, taking place mostly in the United States, where the prevalence of the disease is high,
- DEINOVE has chosen Medpace as its Clinical Research Organization (CRO)  to prepare and oversee the trial, notably because of their experience with the target disease,
- The trial is scheduled to begin mid-2019,
- This clinical program will be the focal point of DEINOVE's antibiotic strategy in the coming months, as the Company has decided not to exercise its option on the NBTI program.
DEINOVE (Euronext Growth Paris: ALDEI), a French biotech company that uses a disruptive approach to develop innovative antibiotics and bio-based active ingredients for cosmetics and nutrition, is preparing the Phase II study that will test DNV3837, its most advanced antibiotic candidate, for use against Clostridium difficile infections (CDI). DEINOVE has chosen Medpace (NASDAQ: MEPD) to act as its CRO and to oversee the clinical trial scheduled to begin in 2019.
DNV3837 is a first-in-class antibiotic candidate targeting the treatment of Clostridium difficile infections (CDIs), a disease classified as a priority by the WHO and one of the leading causes of healthcare-associated infections . DNV3837 has demonstrated a promising efficacy profile and acceptable tolerance in Phase I trials. The FDA  has already approved the start of a Phase II study and has granted the DNV3837 program the Qualified Infectious Disease Product (QIDP) designation and Fast Track status  for accelerated product development.
DEINOVE acquired the DNV3837 program in the 1sthalf of 2018. Since then, their clinical development team has worked with a group of healthcare experts in CDI to prepare for the start of a Phase II clinical trial whose purpose is to demonstrate the efficacy of DNV3837 in patients suffering from CDI. Several aspects of the trial design, which had been presented to the FDA prior to the acquisition, have been improved:
- the target patient population was expanded and now covers moderate to severe CDIs for greater progressiveness in treatment assessment;
- it will be a multicenter trial with a major part taking place in the United States, where there is greater prevalence and the regulatory authorities are looking for new treatment options.
The design of the trial has now been finalized for submission of the updated version to the FDA. The selection process of clinical investigation centers is underway. The trial is scheduled to begin mid-year.
DEINOVE has chosen Medpace to oversee the trial. Medpace is an internationally-recognized full-service CRO that notably has a great deal of experience in infectious diseases, especially gastrointestinal infections like CDIs.
Its mission includes support for the clinical trial's design and set-up (protocol review, contacting the clinical investigation centers, etc.), gathering and analyzing data, and interacting with the FDA.
Georges Gaudriault, Scientific Director at DEINOVE, said: "Preparations for the Phase II clinical trial for DNV3837 are moving forward as planned and we are delighted to have executed such an agreement with Medpace for this trial's oversight. Their experience in both the pathology and American regulatory procedures will help us to secure and maximize this trial's progress."
The DNV3837 program is followed by the AGIR program (backed by Bpifrance), whose aim is to add to the portfolio of new molecules from DEINOVE's biodiversity. The option on the NBTI  program will indeed not be exercised, as the data gathered during the assessment phase were not considered to be in line with DEINOVE's expectations for pursuing the program.
Emmanuel Petiot, CEO of DEINOVE, added: "The antibiotics field is a priority for DEINOVE and the DNV3837 program is our spearhead. Furthermore, we have decided not to exercise our option on the NBTI program with REDX Pharma, insofar as our teams' assessment showed obstacles to its development without further optimization. We want to respond quickly and effectively to the health emergency and the lack of innovative antibiotics, and we are focusing our efforts on those programs with the highest possible probability of success."

 "Fast Track" status facilitates the development of the molecule through a faster and more flexible regulatory review of the application. The QIDP designation gives the drug exclusive access to the market for an additional five-year period. These status are granted by the FDA to drugs under development that meet critical and unmet therapeutic needs.
