  • People who are able to follow the trial's requirements and attend all necessary visits
  • People aged 18 years or older

  • People who have a stored tissue sample with enough tumour material for testing (20 slides), or who are able to have a new biopsy taken if needed
  • People whose tumour has a confirmed genetic change (a complete deletion) in one of these genes — SMARCB1, SMARCA4/2, ARID1A/B, PBRM1, BAP1, SMARCC1/2, or another related gene — detected by an approved genetic test, and confirmed by a centralised tissue stain test; the tissue used for this testing must be less than 3 years old, or a new biopsy will need to be done; each group (cohort) also has a limit on how many prior treatments a person may have had (confirm with trial site for details of your specific cohort)
  • People who have at least one measurable area of cancer that has not been previously treated with radiation, visible on a CT or MRI scan, and able to be monitored over time

  • People with an estimated life expectancy of more than 12 weeks
  • People whose blood counts and organ function meet specific thresholds, confirmed by blood tests taken within 3 days before starting treatment (confirm with trial site for detailed values)
  • Women who could potentially become pregnant must have a negative pregnancy blood test during screening, and another negative test within 72 hours before starting treatment (or a negative urine test within 24 hours), and must agree to use highly effective contraception plus a barrier method, or abstain from sex, during the trial and for 3 months after the last dose
  • Women who are breastfeeding must agree to stop breastfeeding during the trial and for 3 months after the last dose

  • People who are covered by a social security system or equivalent (this appears to be a French regulatory requirement — confirm with trial site)

Who may not be able to join:

  • People who have taken part in another clinical trial involving an investigational treatment in the last 4 weeks (observational studies without treatment may be acceptable — confirm with trial site)
  • People who received their last cancer treatment less than 21 days before starting the trial drug, or less than five half-lives of that previous treatment, whichever is the longer period
  • People who have had radiation therapy covering more than 20% of their bone marrow within the past 2 weeks, curative radiation or major surgery within the past 4 weeks, or palliative radiation within the past 2 weeks
  • People who have had another separate cancer within the past 5 years, with some exceptions for certain fully treated and low-risk cancers such as some skin cancers or carcinoma in situ (confirm with trial site)
  • People who have been taking high-dose steroid or immunosuppressive medications in the 2 weeks before starting the trial, or who are expected to need them during the trial (some low-dose or inhaled steroid uses may be permitted — confirm with trial site)

  • People with a known history of severe allergic reactions to certain types of antibody-based medicines, or a known allergy to the trial drug or its ingredients
  • People with serious or uncontrolled heart conditions, including abnormal heart rhythm, heart attack within the past 6 months, uncontrolled chest pain, severe heart failure, uncontrolled high blood pressure, or poor heart pumping function below certain thresholds (confirm with trial site for specific values)
  • People who have tested positive for HIV or have AIDS
  • People with an active hepatitis B or hepatitis C infection confirmed by a positive test within the past 28 days
  • People with active tuberculosis
  • People with an ongoing, uncontrolled serious infection (bacterial, fungal, or viral) requiring intravenous treatment (localised skin or nail fungal infections may be acceptable — confirm with trial site)
  • People with any other serious uncontrolled medical condition that the trial doctor considers poorly managed, including certain bleeding disorders
  • People currently taking moderate or strong medications that strongly affect how the body processes the trial drug (a specific class of drugs known as CYP3A inducers — confirm with trial site for a list)
  • People who have received a live or weakened live vaccine within 4 weeks before starting the trial, or who may need one during the trial (COVID-19 vaccines are an exception)
