Brief Summary:


Thymoma and thymic carcinoma are diseases of the thymus. Platinum-based chemotherapy is the standard treatment for these diseases. But in many cases, the disease returns after treatment. Researchers want to see if a new drug can help.


To see if bintrafusp alfa (M7824) is an effective treatment for thymoma and thymic carcinoma.


People age 18 and older who have thymoma or thymic cancer and their disease returned or progressed after treatment with at least one platinum-containing chemotherapy treatment plan, or they have refused standard therapy


Participants will be screened under a separate protocol. Their medical, medicine, and treatment history will be reviewed. They will have a tumor biopsy if they do not have a sample.

Participants will get the study drug once every 2 weeks as an intravenous infusion. For this, a small plastic tube is put into an arm vein.

During the study, participants will undergo the following:

Medicine review

Physical exam

Review of their symptoms and their ability to perform their normal activities

Blood and urine tests

Thigh muscle scan (using MRI)

Tumor assessment (using MRI or CT)

Heart and lung function tests

Thyroid gland test

Skin assessment.

Participants may have tumor biopsies. Some of their blood and biopsy samples will be used for gene testing.

Participants may take the study drug until their disease worsens or they cannot tolerate treatment.

Participants will have follow-up visits 2 and 6 weeks after stopping treatment. Then they will have long-term follow-up visits every 3 months. These may include imaging scans. Visits may be done by phone, with scans (if needed) done at their doctor s office.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
  • INCLUSION CRITERIA: Patients must have histologically confirmed (by the pathology department/CCR/NCI) thymoma or thymic carcinoma. Patients must have had at least one prior line of platinum-based chemotherapy or patient must have refused cytotoxic chemotherapy. Progressive disease must be documented prior to study entry and patients must have advanced, unresectable disease that is not amenable to surgical resection. Disease must be measurable with at least 1 unidimensional measurable lesion by RECIST 1.1. Patients must be aged >18 years. ECOG performance status <1 Patients must have adequate organ and marrow function as defined below:

-absolute neutrophil count >1,500/mm3


>1.5 x 109/L

-platelets >100,000/mm3


> 100 x 109/L

  • hemoglobin >9g/dL (may have been transfused)
  • total bilirubin less than or equal to 1.5 x the upper limit of normal range




<5 x ULN for subjects with documented metastatic disease to the liver

-creatinine clearance greater than or equal to 60 mL/min/1.73 m2 calculated by calculated using eGRF in the clinical lab Negative serum or urine pregnancy test at screening for women of childbearing potential (WOCBP). NOTE: WOCBP is defined as any female who has experienced menarche and who has not undergone successful surgical sterilization or who is not postmenopausal. If necessary, to confirm postmenopausal status an FSH level will be included at screening. The effects of Bintrafusp alfa on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation and for at least 2 months after the last dose of the drug. Patients with previously treated brain or CNS metastases are eligible provided that the subject has recovered from any acute side effects of radiotherapy and does not require treatment with steroids, and any whole brain radiation therapy was completed at least 2 weeks prior to enrollment. Ability of subject to understand and the willingness to sign a written informed consent document.

EXCLUSION CRITERIA: History of allergic reactions attributed to compounds of similar chemical or biologic composition to Bintrafusp alfa. Prior treatment with PD-1 or PD-L1-directed immune checkpoint blockade is not permitted. Prior treatment with other immunomodulating drugs such as cancer vaccines is permitted based on investigators discretion as long as treatment was not discontinued due to life-threatening adverse events (laboratory abnormalities alone with prior therapy will not exclude patients from this trial). Concurrent treatment with a non-permitted drug Prior anticancer treatment within 14 days before treatment (e.g., cytoreductive therapy, radiotherapy [with the exception of palliative bone directed radiotherapy], immune therapy, or cytokine therapy except for erythropoietin); major surgery within 14 days before treatment (excluding prior diagnostic biopsy); prior systemic therapy (or 5 halflives of a drug, whichever is shorter) with immunosuppressive agents within 14 days before treatment; use of hormonal agents for anti-cancer therapy within 7 days before treatment; or use of any investigational drug within 14 days before treatment. Note: Subjects receiving bisphosphonate or denosumab are eligible provided treatment was initiated at least 14 days before treatment. History of previous malignant disease within the last 2 years with the following exceptions: basal or squamous cell carcinoma of the skin, cervical carcinoma in situ, ductal carcinoma in situ of the breast, papillary or follicular thyroid carcinoma, and nonmuscle invasive bladder cancer. Active or history of autoimmune disease that might deteriorate when receiving an immune-stimulatory agent, with the exception of vitiligo, autoimmune thyroid disease, or pure red cell aplasia that are adequately managed with medical therapy. In addition, anti-acetylcholine receptor binding and anti-striational antibodies will be checked during screening and patients will be ineligible if results are positive, even if there is no clinical history of autoimmune disease. Patients receiving systemic corticosteroids at doses > 10 mg daily prednisone equivalent will be excluded. However, patients on inhaled steroids and adrenal replacement steroid doses up to 10 mg daily prednisone equivalents are permitted in the absence of autoimmune disease as described in exclusion criterion Active infection requiring systemic therapy or significant acute or chronic infections including, among others:

  • Hepatitis B virus (HBV) or hepatitis C virus (HCV) infection at screening (positive HBV surface antigen or HCV RNA if anti-HCV antibody screening test positive).
  • Known history of testing positive for HIV or testing positive for HIV at screening or known acquired immunodeficiency syndrome.

HIV-positive TET patients are ineligible because of the risk of developing opportunistic infections after treatment with an immune checkpoint inhibitor. Additionally, TET patients are at higher risk of developing opportunistic infections due to underlying immune defects. Prior cases of disseminated herpes virus, cytomegalovirus and fungal infections have been documented in this patient population. Prior organ transplantation including allogenic stem-cell transplantation. Persisting toxicity related to prior therapy (NCI CTCAE v. 5 Grade > 1); however, alopecia, sensory neuropathy Grade less than or equal to 2, or other Grade less than or equal to 2 not constituting a safety risk based on investigator s judgment are acceptable. Pregnant or lactating women. Pregnant women are excluded from this study because Bintrafusp alfa is in the class of agents known as antineoplastics/monoclonal antibodies with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with Bintrafusp alfa, breastfeeding should be discontinued if the mother is treated with Bintrafusp alfa. Known alcohol or drug abuse. Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. All other severe acute or chronic medical conditions including immune colitis, inflammatory bowel disease, immune pneumonitis, pulmonary fibrosis or psychiatric conditions including recent (within the past year) or active suicidal ideation or behavior; or laboratory abnormalities that may increase the risk associated with study participation or study treatment administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient inappropriate for entry into this study. Participants with history of bleeding diathesis or recent major bleeding events considered by the Investigator as high risk for investigational drug treatment are also excluded. Administration of live vaccine within 4 weeks prior to treatment.
