What to Expect as a Participant
You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.
In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.
This trial targets 127 participants in total. It began in 2025-12-01 with a primary completion date of 2026-07.

Brief Summary
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 placebo. Throughout the study, participants will: Have their peripheral blood lymphocyte subpopulations tested at baseline and on Days 7 and 14 Undergo safety monitoring for adverse events according to CTCAE 5.0 criteria Provide information on their quality of life during the treatment period Researchers will compare the outcomes of those who continue PRaG-1 to those who receive a placebo to determine if the observed improvement in CD8+ lymphocytes is sustained, which would indicate that the drug is effective in maintaining immune response.
Eligibility Criteria
Inclusion Criteria: 1. Age ≥ 18 years; 2. Participants with solid malignant tumors, with confirmed pathological diagnosis or medical history; they have completed radiotherapy and/or chemotherapy more than six months ago; and peripheral blood CD8+ absolute count (blood drawn before 10:00 AM) below the lower reference limit (LRL); 3. No treatment with immunomodulatory or immunosuppressive agents within the past 2 weeks prior to enrollment; 4. ECOG performance status score of 0-1, with an estimated life expectancy of ≥ 3 months; 5. AST and ALT ≤ 3.0 times the upper limit of normal (ULN) within one week prior to study enrollment; serum creatinine ≤ 2 times ULN; 6. Ability to understand the study and voluntarily provide written informed consent. Exclusion Criteria: 1. History of uncontrolled epilepsy, central nervous system (CNS) disease, or mental disorders, as determined by the investigator to be clinically significant and potentially interfere with the participant's ability to provide informed consent or comply with medication; 2. Significant (i.e., active) cardiovascular disease, including symptomatic coronary heart disease, congestive heart failure classified as New York Heart Association (NYHA) Class II or worse, or serious arrhythmias requiring pharmacological intervention, or history of myocardial infarction within the past 12 months; 3. Known active serious infections, or in the investigator's opinion, presence of major hematological, renal, metabolic, gastrointestinal, or endocrine dysfunction, or other serious, uncontrolled comorbidities; 4. History of allergy to fungi, or to any of the following components: Cordyceps militaris extract powder, D-mannitol, maltitol, microcrystalline cellulose, or magnesium stearate; 5. History of immunodeficiency, including HIV positive status, or diagnosis with other acquired or congenital immunodeficiencies, or a history of organ transplantation, or immunological disorders requiring long-term oral corticosteroid treatment; 6. Acute gout flare 7. Any other condition deemed unsuitable for enrollment by the investigator.
