NUTMEG: This phase II trial is comparing the effect of a chemotherapy drug (Temozolomide) alone and in combination with an immunotherapy drug (Nivolumab) for the treatment of elderly patients with a newly diagnosed glioblastomaA Randomised Phase II Study of NivolUmab and TeMozolomide vs Temozolomide alone in newly diagnosed Elderly patients with Glioblastoma (NUTMEG) to analyse overall survival.

Clinical summary


All patients will receive radiotherapy (40Gy/ 15 fractions, weekdays over 21 days) concurrently with temozolomide (TMZ) tablets 75mg/m2 daily for 21 days. After a 4 week break the experimental group will receive nivolumab intravenous infusions (240 mg days 1 and 15 every 28 days for cycles 1-4; then 480 mg day 1 every 28 days for cycles 5-6) with concurrent adjuvant temozolomide tablets days 1-5, every 28 days) for 6 cycles. TMZ will be dosed at 150mg/m2 for the first cycle. If well tolerated TMZ is then given at 200mg/m2 for cycles 2 - 6. The intervention will not be personalised.

  2. Tissue available for MGMT testing
  3. ECOG 0-2
  4. Life expectancy of >12 weeks
  5. Adequate bone marrow function (platelets > 100 x 10^9/L, ANC > 1.5 x 10^9/L)
  6. Adequate liver function (ALT/AST < 1.5 x ULN)
  7. Adequate renal function (creatinine clearance > 30 ml/min measured using Cockcroft-Gault
  8. Willing and able to comply with all study requirements, including treatment, timing and/or nature of required assessments including MRI
  9. Signed, written informed consent


  1. Specific comorbidities or conditions (e.g. psychiatric) or concomitant medications which may impact with the administration of study related treatments or procedures
  2. Other co-morbidities or conditions that may compromise assessment of key outcomes
  3. Prior chemotherapy or cranial radiation within the last 5 years. Prior or concomitant therapies for GBM (except surgery).
  4. History of another malignancy within 2 years prior to registration. Patients with a past history of adequately treated carcinoma-in-situ, basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or superficial transitional cell carcinoma of the bladder are eligible. Patients with a history of other malignancies are eligible if they have been continuously disease free for at least 2 years after definitive primary treatment.
  5. Significant infection, including chronic active hepatitis B, hepatitis C, or HIV. Testing for these is not mandatory unless clinically indicated
  6. Active, known or suspected autoimmune disease. Subjects with type I 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.
  7. For symptoms related to GBM, the need for >4 mg/day of dexamethasone or >20 mg/day prednisone (or equivalent) at the time of screening.
  8. For a condition other than GBM, the need for >2 mg/day of dexamethasone or >10 mg/day prednisone (or equivalent) or other immunosuppressive medications within 14 days prior to randomisation. Exceptions to this include the use of inhaled or topical steroids >10 mg/day prednisone (or equivalent), which are permitted in the absence of active autoimmune disease.
