Immunotherapy for advanced metastatic solid tumors

Phase 1 Trial of SYNC-T - Immunotherapy Regimen Given After Controlled Cellular Lysis for Patients With Advanced/Metastatic Solid Tumors

This study is testing a new immunotherapy called SYNC-T to see if it can help people with advanced solid tumors that haven't responded to other treatments.

• Study type: Interventional
• Enrollment: 20 (estimated)
• Ages: 18 Years and up
• Sex: All

• Trial ID: NCT05544240 on ClinicalTrials.gov

What this trial studies

This clinical trial evaluates the safety and efficacy of SYNC-T, an immunotherapy using SV-101, designed to combat advanced and metastatic solid tumors. The approach aims to address the complex mechanisms that allow tumors to evade the immune system by employing a combination of therapeutic agents that stimulate various immunological responses. Participants will be closely monitored for their response to treatment and any potential side effects, with a focus on those who have not responded to standard therapies.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 with advanced or metastatic solid tumors that have not responded to previous therapies.

Not a fit: Patients with early-stage cancer or those who have not yet undergone standard treatment options may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced metastatic cancers who have limited or no available standard treatments.

How similar studies have performed: While the specific approach of SV-101 may be novel, other immunotherapy studies have shown promise in treating metastatic cancers, indicating potential for success.

12. In the opinion of the Investigator, there is no other meaningful life-prolonging therapy option available.
13. Adequate bone marrow, renal, and hepatic function, defined as follows:

    a. Bone marrow function without transfusion 30 days before first dosing: i. Absolute neutrophil count ≥ 1.5 x 109/L; Lymphocyte count of ≥ 1.0 x 109/L; Platelet count ≥ 100 x 109/L; ii. Hemoglobin ≥ 9.0 g/dL b. Renal function: i. Estimated glomerular filtration rate ≥30 mL/min/1.73 m2 or creatinine clearance calculated by Cockcroft-Gault equation ≥30 mL/ c. Hepatic function: i. Alanine aminotransferase ≤ 3x upper limit of normal (ULN) ii. Aspartate aminotransferase ≤ 3x ULN iii. Total bilirubin ≤ ULN or total bilirubin ≤ 1.5x ULN with direct bilirubin ≤ ULN of the laboratory in subjects with documented Gilbert's Syndrome iv. Patients with liver metastases ≤5x ULN
14. All clinically relevant toxicities related to prior anticancer therapy must have recovered to Grade ≤1 or baseline (except alopecia or ototoxicity
15. All subjects with female partners of childbearing potential must use effective contraception throughout study treatment and for 120-150 days (4-5 months) after the last dose of study intervention
16. Has at least one lesion that is demonstrable on PET/CT, CT, Ultrasound, or MRI and is accessible for injection

Exclusion criteria:

1. Has a known additional malignancy that is progressing or has required active treatment in the last 3 years, excluding basal and squamous cell carcinoma
2. Has undergone major surgery within 28 days prior to enrollment and has not recovered adequately from the toxicities and/or complications
3. Has an active infection (including tuberculosis) requiring systemic therapy
4. Has a history of (non-infectious) pneumonitis that required steroids or current pneumonitis
5. Has received a live vaccine within 30 days prior to enrollment
6. Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first treatment
7. Has tumor volume or disease burden too great to provide for safe and/or effective treatment as determined by the Principal Investigator after consultation with Syncromune's Chief Medical Officer
8. Subjects who have metastases limited to subcutaneous regions (only skin)
9. Significant cardiac or other medical illness such as severe congestive heart failure, unstable angina, or serious cardiac arrhythmia (e.g., New York Heart Association Class 4), or history of previous heart failure.
10. Malignant pleural effusions or ascites that require immediate intervention
11. Prior history of autoimmune disease except hypothyroidism
12. Any primary or acquired immunodeficiency
13. Active COVID infection or tests positive for COVID day before or day of planned treatment
14. Known or suspected hepatitis B if active infection (subjects with chronic hepatitis B infection must have an undetectable Hepatitis B virus (HBV) viral load on suppressive therapy, if indicated; positive surface antibody alone is not an exclusion)
15. Known or suspected hepatitis C infection which has not been treated and cured unless currently on treatment with an undetectable viral load
16. Prior history of autoimmune disease except hypothyroidism, uncontrolled or unmanaged diabetes, cardiac arrhytmia (unstable or untreated), hypersensitivity, or other illness or disease that in the opinion of the Principal Investigator, with consultation with Syncromune's Chief Medical Officer, makes the subject a poor candidate.Any condition(s) that, in the opinion of the Investigator, would increase the risk for toxicities from study drug, interfere with subject compliance or conduct of this study
