Expanded Access Protocol for the Use of SL-28 in the Treatment of Advanced Solid Tumors

Study Purpose

This is an Expanded Access Program (EAP) that will give the participants access to the drug SL-28 before it is approved by the FDA. Participants in this study will have Advanced Solid Tumors who failed to respond to standard therapy (chemotherapy, immunotherapy) or developed progressive disease at any phase of standard therapy. Researchers think the SL-28 will be effective because SL-28 has a direct activity against different types of tumors. SL-28 is a cell-based therapy, based on leukocytes isolated from healthy donors and are activated through the proprietary process. After quality assessment (sterility, viable cell count, purity, and absence of infectious diseases), they are stored at -80°C until use. Upon need, the SL-28 is thawed, followed by checking their viability, count, and sterility. Adult and older adult patients aged 18 to 65+ who meet the eligibility criteria will be included in the study. Patients receive SL-28 IV once daily on days 1-5 and 8-12. Based on the patient's response, the need for additional injections will be evaluated. If improvements in the patient's condition are confirmed by MRI, further injections can continue on a rate 5 days a week.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	Unknown
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Expanded Access
Eligible Ages	2 Years and Over
Gender	All

Exclusion Criteria:

- Untreated or active primary central nervous system (CNS) tumor or metastasis; - Patients diagnosed of having primary and secondary immunodeficiencies; - Patients with disease of any major organ system that would compromise their ability to withstand therapy.

- Arterial/venous thrombosis events that occurred in the 12 months before enrollment, such as cerebrovascular accidents (including temporary ischemic attacks, cerebral hemorrhage, cerebral infarction), deep vein thrombosis, and pulmonary embolism; - Known allergy to any of the agents or their ingredients used in this study; - Patients who are on hemodialysis; - Pregnant or breast-feeding women; fertility patients who are unwilling or unable to take effective contraceptive measures; - Patients with untreated positive blood cultures or progressive infections.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT06872489
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
