Brief Summary

This is a multi-center phase II study of brentuximab vedotin in combination with bevacizumab for the treatment of refractory CD-30+ germ cell tumors (GCT) after disease progression on imaging and/or tumor marker progression documented by serially rising alpha-fetoprotein (AFP) or beta human chorionic gonadotropin (bHCG) measured on at least 2 consecutive visits and determined by treating physician to be clinically significant. Patients unable to receive 2nd line of platinum-based chemotherapy due to toxicity or refusal would also be eligible.

Outcome Measures

Primary Outcomes (1)

• Disease Response Rate as Defined by the RECIST 1.1 Criteria, Integrated With Tumor Marker Response.

  Changes in the largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria. In addition to CT scan to assess for disease evaluation, whole body bone scans will be done for patients with known or suspected bone metastases to assess for bone lesions.

  1 year

Secondary Outcomes (3)

• Number of Participants Experiencing Progression Free Survival

  2 years

• Number of Participants Who Were Alive at 2 Years - Overall Survival

  2 years

• Number of Participants Experiencing Adverse Events (AE) and Severe Adverse Events (SAE)

  2 Years

Study Arms (1)

Eligibility Criteria

• Age: 18 Years+
• Sex: male
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Male, ≥ 18 years of age
• Diagnosis of CD-30 positive germ cell tumor. CD30 expression will be tested by immunohistochemistry (IHC) in archival or fresh tumor tissue as is routinely done for diagnosis.
• Disease progression on imaging or tumor marker progression (clinical significance of tumor marker progression to be decided per the discretion of treating physician) after at least 2 lines of platinum-based chemotherapies unless patient is ineligible for further platinum based chemotherapy or refuses 2nd line platinum based chemotherapy due to toxicity. For primary mediastinal germ cell tumors, failure of first-line chemotherapy will be accepted. Prior high dose chemotherapy with hematopoietic stem cell rescue is allowed. Prior treatment with bevacizumab is allowed.
• At least 3 weeks should have elapsed since the last treatment (e.g. chemotherapy, targeted small molecule therapy, immunotherapy or radiation) and must have recovered to grade 1 or better from the acute effects of prior therapy.
• Presence of measurable disease according to RECIST 1.1
• ECOG performance status 0 or 1
• Adequate marrow and organ function within 28 days prior to study registration as defined below:
• Leukocytes \> 3,000/µL
• ANC \> 1500/µL
• Hemoglobin ≥ 9 g/dL, Note: Blood transfusion will be allowed for patients with hemoglobin \< 9 g/dl and G-CSF is allowed for neutropenic patients at time of enrollment.
• Platelets \> 100,000/mm3
• Creatinine: ≤3mg/dl OR if serum creatinine \> 3 mg/dl, estimated GFR \>30 mL/min/1.73m2
• INR: \<1.5 x institutional upper limit of normal OR \< 3 if on warfarin or other anticoagulants. There should be no evidence of active bleeding while on anticoagulants.
• Total bilirubin: ≤ 2 x institutional upper limit of normal (ULN)
• SGOT (AST) or SGPT (ALT): \< 3 x institutional upper limit of normal (\< 5 x ULN if liver metastases present)

You may not qualify if:

• Prior treatment with Brentuximab Vedotin.
• Known active brain metastases and or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided brain metastases are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to study registration. This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability.
• History of blood clots, pulmonary embolism, or deep vein thrombosis in previous 6 months unless controlled by anticoagulant treatment
• Known history of HIV
• Known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA \[qualitative\] is detected)
• Received a live vaccine within 1 week prior to the first dose of study treatment
• Has active autoimmune disease that required systemic treatment with use of disease modifying agents, corticosteroids or immunosuppressive drugs
• Any clinically significant active infection that requires systemic treatment at the time of enrollment.
• Known allergy to bevacizumab or brentuximab vedotin or any of its excipients
• Patients who have congestive heart failure (NYHA Class III or IV), unstable angina, sustained ventricular tachycardia, ventricular fibrillation, clinically significant bradycardia, advanced heart block or a history of acute myocardial infarction (MI) within 6 months of study registration
• History of abdominal fistula, gastrointestinal perforation, or intra-abdominal abscess in previous 6 months
• Prior major surgery within the previous 28 days of study registration and/or presence of any non-healing wound, fracture, or ulcer.
• Use of an investigational agent within the previous 28 days of study registration.
• Poorly controlled hypertension \[defined as systolic blood pressure (SBP) of ≥150 mmHg and/or diastolic blood pressure (DBP) of ≥ 90mmHg\]. Note: Initiation or adjustment of antihypertensive medication(s) is permitted prior to study registration
• Arterial thromboembolic events, including transient ischemic attack (TIA), cerebrovascular accident (CVA), unstable angina, or MI within 6 months of study registration
