EMERCell is a biotechnology company bridging immunotherapy research projects to first pharmaceutical development steps


EMERCell ’s focus is to implement the first steps of the pharmaceutical development of innovative therapeutic products, until the first clinical trials.

Immunotherapy and cell therapy are highly potent therapeutic ways to help body’s immune system and to better fit the current therapeutic needs.

The first project of EMERCell is NK-001, in oncology area.

NK-001 Technology

For the first project of the company, EMERCell is developing a generic cell immunotherapy NK-based to be used in synergy with monoclonal antibodies (MAbs) to treat refractory patients in oncology. This new and innovative drug therapy called NK-001 consists of allogeneic Natural Killer (NK) cells which are activated & amplified ex vivo according to a patented process.

NK-001 Project story

NK-001 project : new Advanced Therapy Medicinal Product (ATMP) development using a patented process to amplify and activate allogeneic Natural Killer (NK) cells.

NK-001 project has been presented twice at the French Regulatory Authorities (ANSM), in 2012 before EMERCell creation, and in 2016 for a review of the preclinical & clinical development plans.

The impact of the association between EMERCell NK and monoclonal antibodies directed against tumor antigens is currently being evaluated: a collaborative program funded by the Fonds Unique Interministériel (a French governmental funding) on B lymphoma is ongoing.

Q4 2017, in vivo proof of concept & preclinical regulatory experiments are ongoing on immunodeficient mice for B lymphoma application.

First ANSM meeting focused on project presentation
Company creation
NK-001 selection in "34 plans de réindustrialisation de la France"
ADI funding, Région Occitanie/BPI
NK-001 project eligibility for "20ème AP du FUI"
Scientific advice, ANSM development plan review
Preclinical data
in vivo proof of concept & preclinical regulatory experiments are ongoing on immunodeficient mice for B lymphoma application.
Expected beginning of clinical development

Development strategy : Which steps ?

After NK-001 therapeutic tool industrial production, NK cells being hematological cells, the proof of concept is suggested initially in the treatment of onco-hematological pathologies: First phase in CD20 refractory lymphoma with a clinically well-known MAb (Rituximab), and second phase in refractory AML (Acute Myeloid Leukemia). Then NK-001 will be tested with Trastuzumab (or equivalent) on solid tumor expressing HER2.
