Radiation Therapy and Intratumoral Autologous Dendritic Cells in Soft Tissue Sarcomas (STS)

A Phase II Study Evaluating Neoadjuvant Administration of High Dose Radiation Therapy and Intratumoral Autologous Dendritic Cells in Patients With High-risk Soft Tissue Sarcomas

The purpose of this study is to determine if injection of the participant's our own immune related white blood cells (called dendritic cells) into their tumor will strengthen their immune system to fight against their cancer.

干预/治疗
有源比较器:External Beam Radiation Therapy (RT)
Arm A - University of Florida - External Beam Radiation Therapy (RT) - As outlined in Intervention Description

Day 1: Start external beam RT, 25 fractions from days 1-33 administered Monday through Friday only (no conventional external beam RT on days 6, 7, 13, 14, 20, 21, 27, or 28

Days 57-70: Surgery will occur 3-5 weeks after the final dose of external beam RT.

Day 78-91: First post-operative visit

Days 91-365: Clinical follow-up

Beyond day 365, follow-up will be conducted using the standard of care approach applicable to these patients for the determination of disease recurrence, progression and survival.

实验性的:External Beam RT + DC Injection
Arm B - Moffitt Cancer Center - External Beam RT + Autologous Dendritic Cells (DC) Injection - As outlined in Intervention Description

Day 1: Start external beam RT, 25 fractions from days 1-33 administered Monday through Friday only (no conventional external beam RT on days 6, 7, 13, 14, 20, 21, 27, or 28

Days 57-70: Surgery will occur 3-5 weeks after the final dose of external beam RT.

Day 78-91: First post-operative visit

Days 91-365: Clinical follow-up

Beyond day 365, follow-up will be conducted using the standard of care approach applicable to these patients for the determination of disease recurrence, progression and survival.

Prior to each injection on Arm B, patients may receive prophylactic doses of a first generation cephalosporin antibiotic per physician discretion.

Following each DC injection, Arm B patients will assess procedure-associated pain on a scale of 0-10. The next Monday following each DC injection, the patient will be called and questioned about such procedure associated toxicities.

研究衡量的是什么?

主要结果指标

结果测量
措施说明
大体时间
Number of Participants With Enhanced T Lymphocyte Immune Response Specific for Soft Tissue Sarcoma Tumor Associated Antigens(STS-TAAs)
大体时间:11 weeks per participant
Investigate the ability of an intensified radiation therapy (RT) regimen (namely, conventional RT with a high-dose hypofractionated boost) and Dendritic Cell (DC) administration to induce an enhanced T lymphocyte immune response specific for STS-TAAs. Criteria for immune response evaluation: Individual patients were considered as responders to TAAs if at any time point the response in IFN-γ ELISPOT assay was found higher than 30 spots per 200,000 cells or in proliferation assay higher than 3000 counts/min (CPM) AND the response in IFN-γ ELISPOT or proliferation assays to tumor cell lysates (TCL) or Ad-Surv was found more than 2SD higher than the response to corresponding control lysate or Ad-c at the same time point AND 2SD higher than the response to the same stimuli at a base line (before start of the treatment).
11 weeks per participant

次要结果测量

结果测量
措施说明
大体时间
Number of Participants With Treatment Emergent Serious Adverse Events (SAEs) and Adverse Events (AEs)
大体时间:11 weeks per participant
Evaluate the safety of intratumoral injections of DCs in combination with an intensified RT regimen patients with high-grade large STS. Toxicity assessments were performed weekly to include assessments for: constitutional symptoms, fever, fatigue; common radiation side effects; special attention was paid to DC injection and biopsy related toxicity. Only treatment related SAEs and AEs are reported for this measure.
11 weeks per participant
