NCT03845712
An Open-Label Study of Continuation Treatment With Combination Pyrimidine Nucleosides in Patients With TK2 Deficiency
This is a Phase 2 prospective open-label treatment study of the safety and efficacy of doxecitine and doxribtimine in study participants with thymidine kinase 2 (TK2) deficiency who participated in the retrospective study MT-1621-101 \[NCT03701568\] or who were receiving nucleos(t)ide treatment and were approved by the Sponsor.

NCT03639701
Treatment of TK2 Deficiency With Thymidine and Deoxycytidine
Patients with confirmed mitochondrial DNA depletion syndrome 2 (thymidine kinase 2 \[TK2\] deficiency) have reduced levels of nucleotides (deoxythymidine monophosphate and deoxycytidine monophosphate) for mitochondrial DNA synthesis. This results in mitochondrial DNA depletion syndrome (i.e less number of functional mitochondrial DNA). Patients with confirmed TK2 deficiency will be treated with open label deoxythymidine (dThd) and deoxycytidine (dCyt), which are nucleotide precursors, with the expectation that the cells could make additional mitochondrial DNA. This in turn may help reduce the clinical symptoms.
