(1) Severe Congenital Neutropenia type 4 (SNC4) due to a deficiency in G6PC3, a phosphatase of the endoplasmic also known a Ubiquitous glucose-6-phosphatase and (2) the neutropenia in Glycogen Storage Disease type 1b due to a deficiency in the glucose-6-phosphate transporter (G6PT / SLC37A4) of the endoplasmic reticulum.

| Main Objective: Ubiquitous glucose-6-phosphatase deficiency (G6PC3) and glucose-6-phosphate transporter deficiency (G6PT / SLC37A4) both cause neutropenia. The purpose of our trial is to test the effect of the effectiveness of Empagliflozin on the urinary excretion and elimination of 1,5-anhydroglucitol from the blood in patients with G6PT deficiency (GSD Ib) and those who are deficient in G6PC3. This should allow patients to significantly lower the level of the toxic compound 1,5-anhydroglucitol-6-phosphate, that we found to accumulate in their neutrophils, and thereby treat their neutropenia. Empagliflozin (marketed in Belgium as Jardiance®) belongs to the class of drugs known as oral hypoglycemic agents. This project is the outcome of the work from researchers and doctors looking after these patients to translate the results from fundamental research, to be soon published in PNAS (Veiga-da-Cunha et al.), into a clinical trial that will very likely benefit the patients.;Secondary Objective: Not applicable;Primary end point(s): -Safety: absence of hypoglycaemia due to gliflozin treatment. -Efficacy: Increased neutrophil count;Timepoint(s) of evaluation of this end point: Day 2, day 3, day 5, day 7, day 14, day 21, day 28, day 35, day 42, day 49, day 56 | — |
