Study of Nogapendekin Alfa Inbakicept and iNKT Cells in Critically Ill Adults With Severe Community-Acquired Pneumonia

This is a Phase 3, randomized, blinded, and placebo-controlled clinical trial investigating a new combination treatment for critically ill adults who have severe community-acquired pneumonia, especially if they also have sepsis or acute respiratory distress syndrome. The study aims to determine if adding the experimental agents, Nogapendekin Alfa Inbakicept and iNKT cells, to standard medical care can reduce the 28-day all-cause mortality rate compared to standard care alone with a placebo.

Evaluation of the Effect of Cordycepin on CD8+ Lymphocytopenia in Patients With Solid Tumors

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.

PRaG-1 Plus PRaG Therapy in Advanced Solid Tumors: A Prospective Clinical Trial (PRaG 10.0)

The goal of this clinical trial is to learn if a combination treatment using PRaG-1 Cordycepin Tablets with radiation therapy, immune-boosting injections, and immunotherapy drugs can help patients with advanced solid tumors. It will also assess safety. The main questions it aims to answer are: Does this treatment improve immune function and slow tumor growth? What side effects or risks occur during treatment? Participants will: Take PRaG-1 Cordycepin Tablets (a natural compound derived from Cordyceps fungus) orally: higher dose for 7 days before radiation, then lower daily dose for 2 weeks Receive targeted radiation therapy to the tumor area (5-12 Gy total in 2-3 sessions) Get daily immune-boosting injections (GM-CSF) for 7 days starting with radiation Receive immunotherapy drugs (PD-1/PD-L1 inhibitors) within one week after radiation Have blood drawn and small tumor tissue samples taken before and after the first two treatment cycles for immune analysis All participants will receive this combination treatment; there is no placebo or alternative treatment group in this study.
