What the trial is, and whether it could suit you
The goal of this clinical trial is to evaluate the effectiveness of PRaG-1 in improving CD8+ lymphocytopenia in patients with solid tumors who are tumor-free for more than six months after completing radiotherapy and/or chemotherapy. It will also assess the safety of PRaG-1 Cordycepin in these patients. The main questions it aims to answer are:
Does PRaG-1 increase CD8+ lymphocyte counts by more than 25% in this patient population? Does the effect of PRaG-1 maintain when treatment is discontinued? What are the safety and tolerability profiles of PRaG-1 during and after the treatment period? Participants will receive open-label PRaG-1 (one tablet in the morning and one in the evening) for 14 days, and those who show a response (CD8+ lymphocytes increase by more than 25%) will enter a 14-day randomized withdrawal period, where they will be assigned to continue PRaG-1 or switch to a placeb
