Background:

Some cancers have tumor cells that lack specific genes, called SMARCB1 and SMARCA4. These types of cancer occur in children and young adults. These cancers are rare, but they are aggressive and hard to treat. Most people who get these cancers survive only months or years. Better treatments are needed.

Objective:

To test a drug (tiragolumab) alone and combined with a second drug (atezolizumab) to treat SMARCB1 and SMARCA4 deficient cancers.

Eligibility:

People aged 3 years or older with SMARCB1 or SMARCB4 deficient cancer. The cancer must have come back after treatment; failed to respond to treatment; or have no known standard treatment.

Design:

Participants will be screened.

Participants may get a central line. This is an opening into a large vein, usually in the chest, that stays in place for a long time. Blood samples can be taken from the central line, and drugs can be administered into it; that way, participants do not need to have a new needle inserted every time.

Treatment will be given in 21-day cycles. Both study drugs are given through a tube placed into a vein in the body. This will be done slowly over 1 hour or more. Participants will receive 1 or both drugs on the first day of each cycle.

Throughout the study, participants will have frequent blood and urine tests. They will have imaging scans and tests of their heart and lung function.

They may have blood and tissue samples stored for future research.

Participants may continue to receive treatment for up to 5 years.

Eligibility

INCLUSION CRITERIA:

1. Age - Patients must be >= 12 months of age at the time of study enrollment. For Part A, patients must be <18 years old at enrollment. For Part B, there is no upper age limit. The Part B (Phase 2) cohorts will initially open concurrently with the Part A but will only enroll patients at least 18 years of age. Patients <18 years of age will be included in the Part B cohorts only after the tiragolumab monotherapy dose has been assessed to be safe in the Part A portion.

2. Diagnosis - Patients must have SMARCB1 (INI1) or SMARCA4 deficient tumors verified through institutional IHC or molecular confirmation of a pathologic tumor bi-allelic SMARCB1 (INI1) or SMARCA4 loss or mutation from a CLIA certified lab with the following disease histologies:

A. Renal medullary carcinoma

B. Malignant rhabdoid tumor (extra-CNS)

C. Atypical teratoid rhabdoid tumor (CNS)

D. Poorly differentiated chordoma

E. Epithelioid sarcoma

F. Other SMARCB1 or SMARCA4 deficient tumors

Note: Documentation of the institutional IHC or molecular testing must be uploaded via the RAVE system

3. Disease Status - Part A: Patients must have either measurable or evaluable disease. Part B: Patients must have either measurable disease per RECIST v1.1 for non-CNS tumors or CNS response criteria for CNS tumors.

4. Therapeutic Options - Patients must have relapsed, refractory disease or newly diagnosed disease for which there is no known curative therapy or therapy proven to prolong survival with an acceptable quality of life.

5. Performance Status - Patients must have a performance status corresponding to ECOG scores of 0, 1 or 2 (Karnofsky/Lansky score of >= 50). Use Karnofsky for patients > 16 years of age and Lansky for patients <= 16 years of age. Note: Neurologic deficits in patients with CNS tumors must have been stable for at least 7 days prior to study enrollment. Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.

EXCLUSION CRITERIA

1. Pregnancy or Breast-Feeding

Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies, OR because there is yet no available information regarding human fetal or teratogenic toxicities. Pregnancy tests must be obtained in girls who are post-menarchal. Males or females of reproductive potential may not participate unless they have agreed to use two effective methods of birth control, including a medically accepted barrier or contraceptive method (eg, male or female condom) for the duration of therapy and at least 90 days after final dose of tiragolumab and 150 days after final dose of atezolizumab, whichever is later. Abstinence is an acceptable method of birth control.

It is not known if atezolizumab or tirgolumab are present in breast milk; however, IgG immunoglobulins are found in milk. Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended during therapy and for at least 150 days after the last dose of atezolizumab and 90 days after the last dose of tiragolumab, whichever is later.
