Brief Summary:

Background:

Immunotherapy drugs help the body to fight cancer. Scientists think that combining some of these drugs will make them work better than when used alone. This may be true for many types of cancer, including castration-resistant prostate cancer (mCRPC).

Objective:

To test if the combination of the drugs BN-brachyury, M7824, ALT-803, and Epacadostat is safe and shrinks tumors.

Eligibility:

People ages 18 and older with mCRPC or another metastatic cancer

Design:

Participants will be screened with:

  • Medical history
  • Physical exam
  • CT or MRI scans
  • Possible bone imaging
  • Blood, urine, and heart tests
  • Possible tumor biopsy

Participants will be treated with a 2-, 3- or 4-drug combinations of the following study drugs in 2-week cycles:

  • Participants will receive M7824 by IV once every 2 weeks.
  • Participants will receive ALT-803 by injection once every 2 weeks. They will record any skin changes at the injection site in a diary.
  • Participants will receive BN-brachyury as 4 injections to different limbs. They will get the first 3 doses 2 weeks apart. Then they will get doses every 4 weeks for 6 months, then every 3 months for 2 years, then every 6 months.
  • Participants will take Epacadostat orally every 12 hours. They will keep a pill diary.

Participants will have physical exams and blood and urine tests at the start of each cycle. They may have scans every 12 weeks.

Participants will continue treatment until their disease gets worse or they cannot tolerate the side effects.

Participants will have a follow-up visit 4-5 weeks after they stop treatment. They will have a physical exam and blood tests. They may be asked to return for scans every 3 months.

Ages Eligible for Study:   18 Years to 99 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria
  • INCLUSION CRITERIA:

Patients must have histologically or cytologically confirmed any solid tumor (Cohort 1) or prostate cancer (Cohort 2). No prior treatment other than testosterone lowering therapy for mCRPC is required.

For the Cohort 1, eligible patients must have a histologically, cytologically or radiographically proven metastatic or locally advanced solid tumor of any type, for which there is no curative standard therapy or standard therapy has failed.

Castrate testosterone level (less than 50ng/dl or 1.7nmol /L). (Patients with a malignancy other than prostate cancer are excluded from this criterion).

Radiological confirmation of metastatic disease, or

Progressive disease at study entry defined as one or more of the following criteria occurring in the setting of castrate levels of testosterone:

--Radiographic progression defined as any new or enlarging bone lesions or growing lymph node disease, consistent with prostate cancer

OR

--PSA progression defined by sequence of rising values separated by greater than 1 week

(2 separate increasing values over a minimum of 1 ng/ml (PCWG3 PSA eligibility criteria). If patients had been on flutamide, PSA progression is documented 4 weeks or more after withdrawal. For patients on bicalutamide or nilutamide disease progression is documented 6 or more weeks after withdrawal. The requirement for a 4-6 week withdrawal period following discontinuation of flutamide, nilutamide or bicalutamide only applies to patients who have been on these drugs for at least the prior 6 months. For all other patients they must stop bicalutamide, nilutamide or flutamide the day prior to enrollment.

Asymptomatic or mildly symptomatic form prostate cancer; no use of regularly scheduled opiate analgesics for prostate cancer-related pain. (Patients with a malignancy other than prostate cancer are excluded from this criterion).

Patients must agree to continuation of androgen deprivation therapy (ADT) with a gonadotropin-releasing hormone analogue/antagonist or bilateral orchiectomy.

(Patients with a malignancy other than prostate cancer are excluded from this criterion).

Age greater than or equal to 18 years.

ECOG performance status less than or equal to 1

Patients must have normal organ and marrow function as defined below:

  • Absolute neutrophil count greater than or equal to 1000/mcL
  • Platelets greater than or equal to 100,000/mcL
  • Hemoglobin greater than or equal to 9.0 g/dL
  • Total bilirubin within normal institutional limits; in patients with

Gilbert s, less than or equal to 3.0 mg/dL

  • AST (AGOT)/ALT (AGPT) less than or equal to 2.5X upper limit of normal. For subjects with liver involvement in their tumor, AST less than or equal to 3.5. (SqrRoot) ULN, ALT less than or equal to 3.5 (SqrRoot) ULN, and bilirubin less than or equal to 3.0 is acceptable
  • Creatinine within 1.5X upper limit of normal institutional limits

The effects of BN-Brachyury, M7824, ALT-803, and Epacadostat on the developing human fetus are unknown. For this reason, men and women must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, during the study and maintain such contraception until 4 months following the last dose of any study agent. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her partner s treating physician immediately.

Ability of subject to understand and the willingness to sign a written informed consent document.

Patients with successfully treated HCV are eligible if HCV viral load is undetectable.

EXCLUSION CRITERIA:

Patients who are immunocompromised as follows:

  • Human immunodeficiency virus positivity due to the potential for decreased tolerance, and potential to be at risk for severe side effects with immunotherapies. These concerns are relevant to all drugs, as drug-drug interactions among antiretrovirals and immunotherapies are yet uncharacterized.
  • Chronic administration (defined as daily or every other day for continued use greater than 14 days) of systemic corticosteroids or other immune suppressive drugs, within 28 days before treatment on study. Nasal, or inhaled steroid, topical steroid creams and eye drops for small body areas are allowed.
  • Patients who have undergone allogeneic peripheral stem cell transplantation, or solid organ transplantation requiring immunosuppression

    • Active autoimmune disease, except patients with type 1 diabetes mellitus, vitiligo, psoriasis, hypo- or hyperthyroid disease not requiring current immunosuppression, or with other endocrine disorders on replacement hormones or are not excluded if the condition is well controlled.

Prostate cancer patients with a history of brain/leptomeningeal metastasis, since these patients have a very poor prognosis and immunotherapy may take time to lead to beneficial clinical effects. Patients with brain or CNS metastases enrolling to arm 1.1 are eligible if they are status post definitive radiotherapy or surgery, and are asymptomatic

History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agents to be used in the cohort the subject will be enrolled into.

Known allergy to eggs, egg products, aminoglycoside antibiotics (for example, gentamicin or tobramycin).

Any condition which, in the opinion of the investigator, would prevent full participation in this trial (including the long-term follow-up), or would interfere with the evaluation of the trial endpoints.

Patients with prior investigational drug, chemotherapy, immunotherapy or any prior radiotherapy (except for palliative bone directed therapy) within the past 28 days prior to enrollment, except if the investigator has assessed that all residual treatment-related toxicities have resolved or are minimal and feel the patient is otherwise suitable for enrollment.

Uncontrolled intercurrent acute or chronic illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (New York Heart Association Class I), hepatic disease, unstable angina pectoris, serious cardiac arrhythmia, requiring medication, uncontrolled hypertension (SBP greater than 170/ DBP greater than 105) or psychiatric illness/social situations within 12 months that would limit compliance with study requirements.

Use of herbal products that may decrease PSA levels (e.g. saw palmetto)

Patients who have had chemotherapy for metastatic castration-resistant prostate cancer within the past year. (Patients who have had docetaxel for metastatic castration sensitive per CHAARTED data may enroll as long as they did not have progressive disease while on docetaxel and are 3 months removed from treatment, with all treatment related toxicities resolving to at least grade 1.)

Patients who have undergone major surgery within 4 weeks of enrollment. A biopsy will not preclude a patient from starting study.

Patients with a history of hepatitis B (HBV) are excluded due to potential risk for viral reactivation and resulting liver injury in persons with latent HBV
