Brief Summary:

The purpose of this research study is to determine the safety and tolerability of talimogene laherparepvec when combined with radiation therapy.

Approximately 30 people will take part in this study conducted by investigators at the University of Iowa.


Condition or disease Intervention/treatment Phase
Soft Tissue Sarcoma Drug: Talimogene Laherparepvec Radiation: Radiotherapy Phase 1 Phase 2

Detailed Description:
This is a single-arm open-label phase Ib and phase II clinical study assessing the safety and relative efficacy of concurrent talimogene laherparepvec in combination with radiotherapy in patients with soft tissue sarcomas. Patients will be treated with neoadjuvant radiation and weekly intratumoral injections of talimogene laherparepvec. Weekly injections of talimogene laherparepvec will be continued until surgery. Surgery will be performed 4-6 weeks from the end of radiation therapy to allow for resolution of acute toxicities per current standard of care.

Arm Intervention/treatment
Experimental: Treatment

Talimogene Laherparepvec in combination with radiotherapy

Talimogene Laherparepvec Dose Levels:

• Initial dose for all = talimogene laherparepvec up to 4.0 mL of 106 PFU/mL

Drug: Talimogene Laherparepvec
Talimogene Laherparepvec

Radiation: Radiotherapy
Concurrent Preoperative Radiation. External Beam Radiation Therapy (EBRT) will be given at the standard dose for resectable soft tissue sarcomas. according to the NCCN sarcoma guidelines.




Primary Outcome Measures :
  1. Phase 1b: Number of Participants With Dose Limiting Toxicities (DLTs) [ Time Frame: 14 weeks ]
    A DLT is defined as any of the following talimogene laherparepvec-related toxicity or related to the combination of talimogene laherparepvec and radiation therapy during treatment and up to 4 weeks after the last talimogene laherparepvec injection: Grade 3 or greater immune-mediated adverse events, Grade 3 or greater allergic reactions, any grade plasmacytoma, any other unexpected grade 3 or greater hematologic or non-hematologic toxicity, with the exceptions of: any grade of alopecia, expected radiation related skin toxicity of any grade, Grade 3 arthralgia or myalgia, brief (< 1 week) grade 3 fatigue, Grade 3 fever, Grade 3 diarrhea or vomiting responding to supportive case.

  2. Phase 2: Number of Subjects With Pathologic Tumor Necrosis ≥ 95% Following Concurrent Radiation Therapy and Talimogene Laherparepvec. [ Time Frame: 14 weeks ]
    At the end of the neoadjuvant therapy, patients will undergo resection of the treated tumor. The percentage of post treatment tumor necrosis must be documented. The primary end point for this study is pathologic complete response (pCR), and is defined as ≥ 95% tumor necrosis following concurrent radiation therapy and talimogene laherparepvec.


Secondary Outcome Measures :
  1. Overall Response Rate (ORR) as Measured by RECIST [ Time Frame: 24 months ]
    Overall response rate (ORR) as measured by RECIST 1.1. Complete response is the disappearance of all target lesions.Partial response is a 30% decrease in the sum of the longest dimensions of the target lesions, relative to baseline. Progressive disease is an increase of 20% or more in the sum of the longest dimension of target lesions. Stable disease is a decrease in the tumor size of < 30% or an increase of < 20%..

  2. Time to Disease Progression (TTP) [ Time Frame: 24 months ]
    TTP is defined as the time from enrollment until objective tumor progression including local and distant recurrences as measured by RECIST 1.1. Complete response is the disappearance of all target lesions.Partial response is a 30% decrease in the sum of the longest dimensions of the target lesions, relative to baseline. Progressive disease is an increase of 20% or more in the sum of the longest dimension of target lesions. Stable disease is a decrease in the tumor size of < 30% or an increase of < 20%.

  3. Overall Survival Rate (OS) at 5 Years [ Time Frame: 5 years ]
    Subjects will be followed for overall survival rate (OS) at 5 years from the last enrollment

  4. Number of Participants With Adverse Events (AEs) [ Time Frame: 14 weeks ]
    To further assess the safety of talimogene laherparepvec given concurrently with preoperative external beam radiation in sarcoma patients.Information regarding the occurrence of adverse events will be collected from the time the subject signs the informed consent form and throughout their participation in the study, including a period of 30 days after the last dose of study drug.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Subject has provided informed consent.
  • Histologically confirmed diagnosis of locally advanced STS that is unresectable with clear wide margins, for which preoperative radiotherapy is considered appropriate.

EXAMPLES:

  • Resectable stage IIB, III, and IV disease that are not suitable for surgically resection alone due to inability to achieve clear margins.
  • Including metastatic (stage IV) disease for which radiotherapy and surgical resection are indicated.
  • Except certain histologic subtypes: GIST, Desmoid, Ewing sarcoma, Kaposi sarcoma, and bone sarcomas.
  • Previous treatment: prior systemic anti-cancer treatment consisting of chemotherapy, immunotherapy, or targeted therapy are allowed provided therapy completed at least 1 year prior to enrollment.
  • No prior Talimogene laherparepvec or tumor vaccines allowed.

    • Patient must have measurable disease:
  • Tumor size at least ≥ 5 cm in the longest diameter as measured by CT scan or MRI for which radiation is feasible.

    • Patient must have injectable disease (direct injection or ultrasound guided).
