Trial of Anti-Tim-3 in Combination With Anti-PD-1 and SRS in Recurrent GBM

Not Recruiting

Trial ID: NCT03961971


This phase I trial studies the side effects of stereotactic radiosurgery with MBG453 and spartalizumab in treating patients with recurrent glioblastoma multiforme (GBM). Stereotactic radiosurgery is a specialized radiation therapy that delivers a single, high dose of radiation directly to the tumor to more precisely target the cancer. Monoclonal antibodies, such as MBG453 and spartalizumab may interfere with the ability of tumor cells to grow and spread. Giving stereotactic radiosurgery together with immunotherapy may be a better treatment for GBM.

Inclusion Criteria:

   1. Patients must provide written informed consent prior to any screening procedures.

   2. Age 18 years or older.

   3. Willing and able to comply with scheduled visits, treatment plan and laboratory tests

   4. Must have WHO Grade IV Glioblastoma or gliosarcoma based on histopathological OR
   molecular criteria

   5. Patients tumor target (GTV) should be ≤ 5 cm.

   6. a) Must have received first-line multimodal therapy with surgery (resection or biopsy)
   followed by radiation and Temozolomide (unless known MGMT promoter unmethylated) AND
   b) Must have completed at least 21 days of combination and Temozolomide therapy
   (unless known MGMT promoter unmethylated. . An interval of at least 12 weeks after the
   end of combination radiation therapy + Temozolomide is required unless there is: i.)
   Histopathologic confirmation of recurrent tumor, or ii) new enhancement on MRI outside
   of the radiotherapy treatment field. (*NOTE: Patients treated with Optune device or
   who received Gliadel wafers placed during the first surgery are eligible.

   7. Must have no more than 2 recurrences of either GBM or gliosarcoma. Recurrence must be
   confirmed by diagnostic biopsy/surgery with local pathology review OR
   contrast-enhanced MRI measurable by RANO criteria. (*NOTE: Patients diagnosed with WHO
   Grade III that undergo surgical resection and are found to have WHO Grade IV or
   gliosarcoma are considered eligible).

   8. Prior gamma knife, stereotactic radiosurgery, or other focal high-dose radiotherapy is
   allowed but the subject must have either histopathologic confirmation of recurrent
   tumor, or new enhancement on MRI outside of the radiotherapy treatment field

   9. Karnofsky Performance Status ≥ 70

10. Must have ability to undergo MRI scans

11. Must be > 30 days since last chemotherapy

12. Must have recovered from severe toxicity of prior therapy. (NOTE: Patients who undergo
   surgical resection must have recovered from surgery (at least 2 weeks) before starting
   study treatment).

13. Subjects must have normal organ and marrow function as defined below:

   WBC ≥ 2,000/mcL absolute neutrophil count ≥ 1,500/mcL platelets ≥ 100,000/mcL
   hemoglobin ≥ 9.0 g/dL lymphocytes ≥ 500/mcL total bilirubin ≤ 1.5X institutional upper
   limit of normal AST/ALT ≤ 3.0 X institutional upper limit of normal creatinine ≤ 1.5X
   institutional upper limit of normal OR Creatinine clearance (CrCl) ≥ 50 mL/min (using
   the Cockcroft-Gault formula)

14. Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy
   test within -7 days prior to the start of therapy. Women must not be breastfeeding.

15. Women of child bearing potential (WOCBP) and men must use a reliable form of
   contraception during the study treatment period and for 150 days following the last
   dose of study drug. In order for a woman to be determined not of child-bearing
   potential, she must have ≥ 12 months of non-therapy-induced amenorrhea or be
   surgically sterile.

Exclusion Criteria:

   1. History of other malignancy, unless the patient has been disease-free for at ≥5 years.
   Curatively treated basal or squamous cell carcinoma of the skin, totally excised
   melanoma of stage IIA or lower, low or intermediate-grade localized prostate cancer
   (Gleason sum ≤7), and curatively-treated carcinoma in situ of the cervix, breast, or
   bladder are allowed regardless.

   2. Any known metastatic extracranial or leptomeningeal disease.

   3. Evidence of acute intracranial / intra-tumoral hemorrhage

   4. History of organ or hematopoietic stem cell (HSC) transplant

   5. Receiving greater than 4 mg dexamethasone/day (or equivalent amount of an alternative
   corticosteroid) for a minimum of 5 days prior to screening visit. Subjects with an
   autoimmune condition requiring systemic treatment with either corticosteroids (> 10 mg
   daily prednisone or equivalent) or other immunosuppressive medications within 14 days
   of study entry *NOTE: Inhaled or topical steroids, and adrenal replacement steroid
   doses > 10 mg daily prednisone or equivalent, are permitted in the absence of active
   autoimmune disease

   6. Prior treatment with immune-modulating therapy, other than steroids.

   7. Pregnant or nursing (lactating) women

   8. Known positive history of HIV, active Hepatitis B, and/or active Hepatitis C

   9. Subjects with active, or recent history of known or suspected autoimmune disease.
   Subjects with Type 1 diabetes mellitus, hypothyroidism only requiring hormone
   replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring
   systemic treatment, or conditions not expected to recur in the absence of an external
   trigger are permitted to enroll

10. Major surgery, outside of a craniotomy/resection, within 2 weeks of the first dose of
   study treatment (mediastinoscopy, insertion of a central venous access device, and
   insertion of a feeding tube are not considered major surgery).

11. Use of any vaccines against infectious diseases (e.g. varicella, pneumococcus) within
   4 weeks of initiation of study treatment

12. Any serious or uncontrolled medical disorder that, in the opinion of the investigator,
   may increase the risk associated with study participation or study drug
   administration, impair the ability of the subject to receive protocol therapy, or
   interfere with the interpretation of study results.

13. Subjects with interstitial lung disease that is symptomatic or may interfere with the
   detection or management of suspected drug-related pulmonary toxicity

14. History of evidence upon physical/neurological examination of other central nervous
   system condition (i.e. seizures, abscess) unrelated to cancer, unless adequately

   physical (e.g. infections disease) illness.
