Summary
Study start date: March 1, 1995
Actual date on which the first participant was enrolled.PROTOCOL OUTLINE: Newly identified patients receive ribose daily for 8 weeks. Patients who improve continue therapy. If improvement then reaches a plateau, uridine (UR) and thymidine (TDR) are added to the regimen. Patients who receive no benefit after 8 weeks of ribose are treated with UR/TDR. Patients who improve after 8 weeks of this combination continue therapy. Ribose is added to the treatment regimen for patients on UR/TDR at entry. At maximal improvement, TDR and UR are sequentially tapered.
