Brief Summary:
This phase I trial studies the side effects of BO-112 when given together with nivolumab before surgery in treating patients with soft tissue sarcoma that can be removed by surgery (resectable). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Immunotherapy with BO-112, may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab and BO-112 before surgery may work better in treating patients with soft tissue sarcoma compared to nivolumab alone.

Detailed Description:

PRIMARY OBJECTIVE:

I. To determine the safety and tolerability of integrating BO-112, and BO-112 with nivolumab in soft tissue sarcoma patients undergoing preoperative radiotherapy.

SECONDARY OBJECTIVES:

I. Determine the change in T cell infiltration at surgical resection from baseline as measured by immunohistochemistry.

II. Assess treatment effect (necrosis score) of BO-112 and BO-112 in combination with nivolumab in soft tissue sarcoma patients receiving preoperative hypofractionated radiotherapy, compared to patients treated on a recently completed phase 2 study of preoperative hypofractionated radiotherapy alone.

III. Evaluate the 2-year rate of local and distant metastasis of BO-112 and BO-112 in combination with nivolumab in patients with localized resectable soft tissue sarcoma receiving preoperative hypofractionated radiotherapy, as compared to historical patients receiving preoperative radiotherapy alone.

EXPLORATORY OBJECTIVES:

I. Evaluate the dynamics of the intratumoral T cell phenotype. II. Assess the capacity to grow ex vivo tumor infiltrating lymphocytes from patients treated with BO-112 and BO-112 in combination with nivolumab.

III. Analyze changes in T-cell receptor (TCR) repertoire in tumor infiltrating lymphocytes and peripheral blood mononuclear cells (PBMCs) between baseline, post-treatment, and ex vivo cultured tumor infiltrating lymphocyte (TIL) samples.

IV. For patients with disease burden outside of the resected lesion, assess imaging response to treatment using Response Evaluation Criteria in Solid Tumors (RECIST) criteria.

OUTLINE:

Patients receive BO-112 intratumorally on days 8 and 15 or 1, 8, and 15 and nivolumab intravenously (IV) over 30-60 minutes on day 8 in the absence of disease progression or unacceptable toxicity. Patients also undergo standard of care radiation therapy on days 8-12 for a total of 5 fractions. Patients then undergo standard of care definitive surgical resection on day 26 to 50.

After completion of study treatment, patients are followed up at 2 weeks, 3 months, and between 6-12, 12-18, and 18-24 months.

Primary Outcome Measures :
  1. Incidence of adverse events (AEs) [ Time Frame: study enrollment through 100 days after the last dose of study drug ]
    AEs will be tabulated by type, severity, and the proportion of subject experiencing the event.


Secondary Outcome Measures :
  1. Immune-oncologic impact of the BO-112 or the combined regimen of nivolumab and BO-112 [ Time Frame: from the date of study drug initiation until 50 days after study drug initiation (or the date of surgery, whichever comes first) ]
    Statistical analysis of immune-oncologic changes will be performed by comparing results from surgical specimens with baseline biopsy specimens. For immunohistochemical parameters, the percentage of CD4+ (cluster of differentiation 4) or CD8+((cluster of differentiation 8) cells will be compared between biopsy and surgical specimens using a paired two-tailed ratio T-test comparing means.

  2. Pathologic treatment effect [ Time Frame: At time of surgery ]
    Will be compared to historical samples receiving preoperative radiotherapy alone. Will use a two-sample paired T-test comparing means.

  • HIGHLY EFFECTIVE METHODS OF CONTRACEPTION

Highly effective methods of contraception have a failure rate of < 1% when used consistently and correctly. WOCBP and female partners of male subjects, who are WOCBP, are expected to use one of the highly effective methods of contraception listed below. Male subjects must inform their female partners who are WOCBP of the contraceptive requirements of the protocol and are expected to adhere to using contraception with their partner. Contraception methods are as follows:

  • Progestogen only hormonal contraception associated with inhibition of ovulation
  • Hormonal methods of contraception including oral contraceptive pills containing combined estrogen + progesterone, vaginal ring, injectables, implants and intrauterine devices (IUDs) such as Mirena
  • Nonhormonal IUDs, such as ParaGard
  • Bilateral tubal occlusion
  • Vasectomized partner with documented azoospermia 90 days after procedure

    • Vasectomized partner is a highly effective birth control method provided that partner is the sole sexual partner of the WOCBP trial participant and that the vasectomized partner has received medical assessment of the surgical success
  • Intrauterine hormone-releasing system (IUS)
  • Complete abstinence

    • Complete abstinence is defined as the complete avoidance of heterosexual intercourse
    • Complete abstinence is an acceptable form of contraception for all study drugs and must be used throughout the duration of the study treatment (plus 5 half-lives of the investigational drug plus 30 days)
    • It is not necessary to use any other method of contraception when complete abstinence is elected
    • Subjects who choose complete abstinence must continue to have pregnancy tests, as specified
    • Acceptable alternate methods of highly effective contraception must be discussed in the event that the subject chooses to forego complete abstinence
    • The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject

      • LESS EFFECTIVE METHODS OF CONTRACEPTION
  • Diaphragm with spermicide
  • Cervical cap with spermicide
  • Vaginal sponge with spermicide
  • Male or female condom with or without spermicide

    • A male and a female condom must not be used together
  • Progestogen-only oral hormonal contraception, where inhibition of ovulation is not the primary mode of action

    • UNACCEPTABLE METHODS OF CONTRACEPTION
