Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Age ≥ 18 years at time of informed consent
• Body weight > 30 kg
• Histologically confirmed diagnosis of GCT (nonseminoma or seminoma in men; non-dysgerminomas, dysgerminomas, or germinomas in women or patients with pineal gland GCT) at MSKCC of any primary site (includes female GCT and intracranial GCT).
• Evidence of measurable disease either by RECIST 1.1 or elevation of serum tumor markers (AFP > 15 ng/mL or HCG >2.2 mIU/ml).
• Patients must have progressed after at least one prior systemic therapy for GCT and meet one of the following criteria:
• a. Patients with evidence of progressive or recurrent GCT after progression prior high dose chemotherapy (HDCT) treatment, defined as meeting at least on of the following criteria: i. Tumor biopsy of new or growing or unresectable lesions demonstrating viable GCT. In the event of an incomplete gross resection where viable GCT is found, patients will be considered eligible for this study.
• ii. Consecutive elevated serum tumor markers (HCG or AFP) that are increasing. Increase of an elevated LDH alone does not constitute progressive disease.
• iii. Development of new or enlarging lesions in the the setting of persistently elevated HCG or AFP, even if the HCG and AFP are not continuing to rise.
• b. Patients deemed not to be a candidate for or benefit from potentially curative HDCT or other curative treatment options defined as follows: i. Patients with inadequate renal function for HDCT. ii. Patients who have had 3 or more lines of prior chemotherapy as this patient population has historically not benefitted from HDCT.
• iii. Patients with late relapse (relapse > 2 years after last therapy) as this patient population has historically not benefitted from HDCT.
• iv. Patient with inadequate stem cell collection to move forward with HDCT. v. Patients with significant medical or psychosocial comorbidities that are felt to be a contraindication to HDCT by the treating investigator.
• NOTE: There is no maximum number of prior treatments allowed "Progression" after prior therapy is defined as any one of the following: NOTE: Patients with clinically growing "teratoma" (normal declining tumor markers and radiographic or clinical progression) should be considered for surgery. In patients with rising tumor markers as their only evidence of disease progression where AFP is <30 or HCG is <15, alternate causes of increased levels of these markers should be ruled out. (e.g., hypogonadism by testosterone suppression of LH, hepatitis, use of marijuana).
• Patients with brain metastases are allowed onto the study as long as patients have completed their treatment for brain metastasis, no longer require corticosteroids, and are asymptomatic. Subjects with neurological symptoms should undergo a head CT scan or brain MRI to exclude brain metastasis, at the discretion of the treating physician.
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
• Adequate normal organ and marrow function as defined below:
• Hemoglobin ≥ 9.0 g/dL
• Absolute neutrophil count (ANC) ≥ 1.0 x 109/L (> 1000 per mm3)
• Platelet count ≥ 100 x 109/L (>100,000 per mm3)
• Serum bilirubin ≤ 1.5 x institutional upper limit of normal (ULN) (≤ 3 x institutional ULN in patient's with Gilbert's syndrome)
• AST (SGOT)/ALT (SGPT) ≤ 2.5 x institutional ULN unless liver metastases are present, in which case it must be ≤ 5x ULN
• Calculated creatinine clearance >30 mL/min by the Cockcroft-Gault formula (Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance
• Evidence of post-menopausal status or negative urinary or serum pregnancy test for female pre-menopausal patients. Women will be considered post-menopausal if they have been amenorrheic for 12 months without an alternative medical cause. The following age-specific requirements apply.
• Women < 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of exogenous hormonal treatment and if they have luteinizing hormone and follicle-stimulating hormone levels in the post-menopausal range for the institution or underwent surgical sterilization (bilateral oophorectomy or hysterectomy).
• Women >/= 50 years of age would be considered post-menopausal if they have been amenorrheic for 12 months or more following cessation of all exogenous hormonal treatments, had radiation-induced menopause with last menses > 1 year ago, had chemotherapy-induced menopause with last menses >1 year ago, or underwent surgical sterilization (bilateral oophorectomy, bilateral salpingectomy or hysterectomy).
• A positive serum pregnancy test must be confirmed by a pelvic US since some NSGCT may secrete beta-hCG and cause a false positive pregnancy. A pelvic US does not need to be repeated with each cycle unless the treating physician thinks it is necessary to do so.

You may not qualify if…

• Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site)
• Previous enrolment in the present study
• Participation in another clinical study with an investigational product during the last 14 days
• Mean QT interval corrected for heart rate (QTc) ≥ 470 ms calculated from 3 electrocardiograms (ECGs) using Fredericia's Correction
• Any previous treatment with a PD-1 or PD-L1 inhibitor, including durvalumab or an anti-CTLA-4, including tremelimumab
• Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) ≤ 14 days prior to the first dose of study drug
• Major surgery within 28 days of starting study treatment. There is no minimum time requirement for minor procedures such as biopsy or vascular access placement.
• Radiation within 14 days of starting study treatment
• Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab or tremelimumab. The following are exceptions to this criterion:
• Intranasal, inhaled, topical steroids, or local steroid injections (e.g., intra articular injection)
• Systemic corticosteroids at physiologic doses not to exceed10 mg/day of prednisone or its equivalent
• Steroids as premedication for hypersensitivity reactions (e.g., CT scan premedication)
• A temporary period of steroids for different indications, at the discretion of the principal investigator (e.g., chronic obstructive pulmonary disease, radiation, nausea, etc)
• Any unresolved toxicity (>CTCAE grade 2) from previous anti-cancer therapy. Subjects with irreversible toxicity that is not reasonably expected to be exacerbated by the investigational product may be included (e.g., alopecia, hearing loss, peripheral neuropathy).
• History of pulmonary fibrosis by imaging or biopsy (including secondary to bleomycin), pneumonitis (including drug induced) requiring steroids ≥ 3 weeks, organizing pneumonia (i.e., bronchiolitis obliterans, cryptogenic organizing pneumonia, etc.), or evidence of active pneumonitis on screening chest computed tomography (CT) scan with associated symptoms.
• Active or prior documented autoimmune or inflammatory disorders (including inflammatory bowel disease [e.g., colitis or Crohn's disease], diverticulitis, celiac disease, systemic lupus erythematosus, Sarcoidosis syndrome, or Wegener syndrome (granulomatosis with polyangiitis, Graves' disease, rheumatoid arthritis, hypophysitis, uveitis, etc)). The following are exceptions to this criterion:
• Patients with vitiligo or alopecia
• Patients with hypothyroidism (eg, following Hashimoto syndrome) stable on hormone replacement
• Any chronic skin condition that does not require systemic therapy
