Clinical Research


This is the research conducted in collaboration with patients.
It is intended to gain a better knowledge and then to be able to treat intelligence genetic diseases


It includes :

Therapeutic Research, Epidemiological Research ,
and Diagnostic Research

Therapeutic Research

This is intended to study medicines which are aimed at treating our patients. The clinical tests are conducted using products in widespread use for other diseases. They are conducted taking maximum precautions. In general this involves comparative testing (double blind testing). Before implementation, the protocols for these studies are subjected to multiple checks by the Jérôme Lejeune Foundation Scientific Council, the French Ministry for Research, the French National Committee for Information Technology and Freedom (C.N.I.L.), the French Ministry of Health (AFSSaPS), the Ethics Committee (C.C.P.P.R.B.), etc.

Several clinical tests are being conducted at the Jérôme Lejeune Medical Centre :

ENTRAIN concerns children suffering from Trisomy 21 (Down's syndrome), between 3 and 30 months old.

TRAFAO is being prepared, to evaluate a long-term treatment for infants suffering from Trisomy 21.

COFAC is being prepared, to study a treatment intended for hyperactive 5- to 11-year old children suffering from Trisomy 21.

TEDDI is also being prepared, and is aimed at adult patients suffering from Trisomy 21.

Epidemiological Research

These studies are essential in order to gain a better knowledge of the diseases and are extremely valuable for guiding future research, including the discovery of new medicines.
Epidemiological studies are under way at the Jérôme Lejeune Medical Centre :

NICOLAS (metabolic study) and TROPHEE (ophthalmological study) are aimed at adult patients (over 18 years old).

The DULAC study concerns a particular form of epilepsy (infantile spasms) in children suffering from Trisomy 21.

The SATGE study concerns the appearance of certain tumours in Trisomy 21.

TREFHOR is conducted in Grenoble and is studying the adaptation to physical exercise in adolescent patients (13 to 18-year olds) suffering from Trisomy 21.
Finally, a very broad epidemiological study concerning all patients suffering from Trisomy 21,
INTREPID is currently being elaborated.

Diagnostic Research

The RMLX study is intended to improve the diagnostics of certain mental deficiencies, where the gene is located on the X chromosome.
