Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • 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:
  • 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.
Show all 29Show fewer
  • Consecutive elevated serum tumor markers (HCG or AFP) that are increasing. Increase of an elevated LDH alone does not constitute progressive disease.
  • 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.
  • 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.
  • Patients with late relapse (relapse > 2 years after last therapy) as this patient population has historically not benefitted from HDCT.
  • 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.
  • Female patients of reproductive potential, defined as not surgical sterile (i.e., bilateral tubal ligation, bilateral oophorectomy, or complete hysterectomy) or post-menopausal (see above for definition) and non-sterilized males who are sexually active with a female partner of reproductive potential must be willing to adhere to the following restrictions:
  • Females of childbearing potential who are sexually active with a non-sterilized male partner must agree to use at least 1 highly effective method of contraception from the time of screening until 180 days after the last dose of durvalumab + tremelimumab combination therapy or 90 days after the last dose of durvalumab monotherapy. Cessation of birth control after this point should be discussed with a responsible physician. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. It is strongly recommended that non-sterilized male partners of a female patient must use male condom plus spermicide throughout this period Not engaging in sexual activity for the total duration of the drug treatment and the drug washout period is an acceptable practice.
  • Non-sterilized males who are sexually active with a female partner of childbearing potential must use a male condom plus spermicide from screening through 180 days after receipt of the final dose of durvalumab + tremelimumab combination therapy or 90 days after receipt of the final dose of durvalumab monotherapy. Periodic abstinence, the rhythm method, and the withdrawal method are not acceptable methods of birth control. Not engaging in sexual activity is an acceptable practice. Male patients should refrain from sperm donation throughout this period. It is strongly recommended that female partners (of childbearing potential) of male patients to also use a highly effective method of contraception throughout this period.
  • Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Durvalumab and Tremelimumab in people with Germ Cell Tumor and Nonseminomatous Germ Cell Tumor, run by Memorial Sloan Kettering Cancer Center at 7 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 29 inclusion and 34 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 18 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

overall response rate (ORR) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03158064.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Sep 2026.
