Stereotactic Body Radiation Therapy and Avelumab Immunotherapy for Treatment of Malignant Mesothelioma

Published: January 17, 2018

Primary Outcome Measures

  • Overall response rate [ Time Frame: 3 years ]
    defined by modified RECIST 1.1 for mesothelioma


Inclusion Criteria
Patient willing and able to provide written informed consent for the trial.

Patient age ≥ 18 at time of consent.

Histologically or cytologically confirmed malignant pleural or peritoneal mesothelioma (MPM).

No plans for surgical resection.

PD-L1 expression in ≥ 5% of cells by IHC (testing will be performed at MSKCC on archival tissue using the Cell Signaling Clone – E1L3N)

At least one prior line of systemic therapy including platinum and pemetrexed.

At least one targetable lesion appropriate for palliative SBRT and one non-target lesion

Karnofsky Performance Score (KPS) ≥ 70%

If of childbearing potential, must be willing to use highly effective mode of contraception for at least one month prior, during, and for 2 months after the end of active therapy

Adequate organ function, defined as:

Absolute Neutrophil Count ≥ 1.5K/mcL.

Platelet count ≥ 100K/mcL.

Adequate renal function as defined by an estimated creatinine clearance ≥ 30 mL/min according to the Cockcroft-Gault formula or serum creatinine ≤ 1.5 x ULN

Hemoglobin > 9g/dL (prior transfusion permitted)

Total bilirubin level ≤ 1.5 × the upper limit of normal (ULN) range

AST and ALT levels ≤ 2.5 × ULN or AST and ALT levels ≤ 5 x ULN (for subjects with documented metastatic disease to the liver).

If the patient received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.
Exclusion Criteria
Currently participating and receiving another study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.

Prior radiation therapy precluding SBRT

Continuous oxygen use

Current use of immunosuppressive medication, EXCEPT for the following: a. intranasal, inhaled, topical steroids, or local steroid injection (e.g., intra-articular injection); b. Systemic corticosteroids at physiologic doses ≤ 10 mg/day of prednisone or equivalent; c. Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication).

Active autoimmune disease that might deteriorate when receiving an immunostimulatory agent. Patients with diabetes type I, vitiligo, psoriasis, or hypo- or hyperthyroid diseases not requiring immunosuppressive treatment are eligible. Replacement therapy (e.g. thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment.

Known prior severe hypersensitivity to investigational product or any component in its formulations, including known severe hypersensitivity reactions to monoclonal antibodies (NCI CTCAE v4.03 Grade ≥ 3)

Prior Therapies:

Treatment with a monoclonal antibody within 4 weeks prior to study Day 1 or has not recovered (i.e., ≥ Grade 1 at baseline) from adverse events due to agents administered > 4 weeks earlier.

Prior chemotherapy, targeted small molecule therapy, within 3 weeks prior to study Day 1 or has not recovered (i.e., ≥ Grade 1 at baseline) from adverse events due to a previously administered agent (excluding Grade 2 neuropathy).

Prior therapy with an anti-PD-1, anti-PD-L1, anti-PD-L2, anti-CD137, or anti- Cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) antibody (including ipilimumab or any other antibody or drug specifically targeting T-cell co-stimulation or checkpoint pathways).

Comorbidities or Prior Conditions

Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.

Prior organ transplantation including allogenic stem-cell transplantation.

Known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or in situ cervical cancer that has undergone potentially curative therapy.

Known history of active TB (Tuberculosis).

Known history of HIV or known acquired immunodeficiency syndrome.

Active Hepatitis B virus (HBV) or Hepatitis C virus (HCV) infection at screening or positive serologies indicating prior infection.

Active infection requiring systemic therapy.

Has evidence of interstitial lung disease or active, non-infectious pneumonitis.

Clinically significant (i.e., active) cardiovascular disease: cerebral vascular accident/stroke (< 6 months prior to enrollment), myocardial infarction (< 6 months prior to enrollment), unstable angina, congestive heart failure (≥ New York Heart Association Classification Class II), or serious cardiac arrhythmia requiring medication.
Pregnant women or women who are breastfeeding or of childbearing potential and not using a highly effective method of birth control for at least one month prior to enrollment. If the risk of contraception exists, male and female subjects must use highly effective contraception throughout the study and for at least 60 days after last avelumab treatment.

a. Highly effective contraception includes either 2 barrier methods (diaphragm, condom by the partner, copper intrauterine device, sponge, or spermicide), or 1 barrier method and 1 hormonal method (any oral, subcutaneous, intrauterine, or intramuscular registered and marketed contraceptive agent that contains an estrogen and/or a progesterone agent).

Vaccination within 4 weeks prior to the first dose of avelumab and while on trial is prohibited except for administration of inactivated vaccines.

Concomitant use of the following medications

Any investigational anticancer therapy.

Any concurrent chemotherapy, immunotherapy, or biologic therapy. Concurrent use of hormones for non-cancer-related conditions (e.g., insulin for diabetes and hormone replacement therapy) is acceptable.

Immunosuppressive medications including, but not limited to systemic corticosteroids (>10 mg/day prednisone or equivalent), methotrexate, azathioprine, and tumor necrosis factor alpha (TNF-α) blockers. Use of immunosuppressive medications for the management of investigational product-related AEs, in subjects with contrast allergies is acceptable. In addition, use of inhaled and intranasal corticosteroids is permitted.
