DETERMINE Trial Treatment Arm 02: Atezolizumab in Adult, Teenage/Young Adults and Paediatric Patients With Cancers With High Tumour Mutational Burden (TMB) or Microsatellite Instability-high (MSI-high) or Proven Constitutional Mismatch Repair Deficiency (CMMRD) Disposition (DETERMINE)

January 4, 2024 updated by: Cancer Research UK

DETERMINE (Determining Extended Therapeutic Indications for Existing Drugs in Rare Molecularly Defined Indications Using a National Evaluation Platform Trial): An Umbrella-Basket Platform Trial to Evaluate the Efficacy of Targeted Therapies in Rare Adult, Paediatric and Teenage/Young Adult (TYA) Cancers With Actionable Genomic Alterations, Including Common Cancers With Rare Actionable Alterations. Treatment Arm 02: Atezolizumab in Adult, Teenage/Young Adults and Paediatric Patients With Cancers With High TMB or MSI-high or Proven CMMRD Disposition.

This clinical trial is looking at a drug called atezolizumab. Atezolizumab is approved as standard of care treatment for adult patients with urothelial cancer, non-small cell lung cancer, extensive-stage breast small cell lung cancer, hepatocellular carcinoma and triple negative cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK.

Atezolizumab works in patients with these types of cancers which have certain changes in the cancer cells called high tumour mutational burden (TMB) or high microsatellite instability (MSI) or proven (previously diagnosed) constitutional mismatch repair deficiency (CMMRD).

Investigators now wish to find out if it will be useful in treating patients with other cancer types which are also TMB/MSH-high or show CMMRD. If the results are positive, the study team will work with the NHS and the Cancer Drugs Fund to see if these drugs can be routinely accessed for patients in the future.

This trial is part of a trial programme called DETERMINE. The programme will also look at other anti-cancer drugs in the same way, through matching the drug to rare cancer types or ones with specific mutations.

Detailed Description

DETERMINE Treatment Arm 02 (atezolizumab) aims to evaluate the efficacy of atezolizumab in adult, paediatric and teenage/young adult (TYA) patients with rare* cancers with high TMB or high MSI or proven CMMRD disposition and in common cancers where high TMB/MSI or proven CMMRD is considered to be infrequent.

*Rare is defined generally as incidence less than 6 cases in 100,000 patients (includes paediatric and teenagers/young adult cancers) or common cancers with rare alterations.

This treatment arm has a target sample size of 30 evaluable patients. Sub-cohorts may be defined and further expanded where promising activity is identified to a target of 30 evaluable patients each.

The ultimate aim is to translate positive clinical findings to the NHS (Cancer Drugs Fund) to provide new treatment options for rare adult, paediatric and TYA cancers.

OUTLINE:

Pre-screening: The Molecular Tumour Board makes a treatment recommendation for the participant based on molecularly-defined cohorts.

Screening: Consenting participants undergo biopsy and collection of blood samples for research purposes.

Treatment: Participants will receive atezolizumab until disease progression, unacceptable toxicity or withdrawal of consent. Participants will also undergo collection of blood samples at various intervals while receiving treatment and at EoT.

After completion of study treatment, patients are followed up every 3 months for 2 years.

  • Male patients with pregnant or lactating partners must be advised to use barrier method contraception (e.g. condom) to prevent drug exposure of the foetus or neonate.

D. Patients must be able and willing to undergo a fresh biopsy.

E. ADULT PATIENTS: Adequate organ function as per haematological and biochemical indices within the ranges shown below. These measurements should be performed to confirm the patient's eligibility.

Haemoglobin (Hb): ≥90 g/L (transfusion allowed)

Lymphocyte count: ≥0.5×10^9/L

Absolute neutrophil count (ANC): ≥1.5×10^9/L (no granulocyte colony-stimulating factor [GCSF] support in preceding 72 hours)

Exclusion Criteria:

A. Diagnosis of urothelial cancer, non-small cell lung cancer, extensive-stage small cell lung cancer, hepatocellular carcinoma or triple negative breast cancer.

B. Patients with rapidly progressing or symptomatically deteriorating brain metastases. Patients with previously treated brain metastases are eligible, provided the patient has not experienced a seizure or had a clinically significant change in neurological status within the 14 days prior to the start of IMP administration. Such patients must be non-dependent on steroids or on a stable or reducing dose of steroid treatment for at least 14 days (or 7 days for paediatric patients) prior to the start of IMP administration. Primary brain or central nervous system (CNS) malignancies are allowed providing the patient is clinically stable (if requiring corticosteroids must be at stable or decreasing doses for at least 14 days for adults and 7 days for paediatric patients prior to the start of IMP administration). Patients who have received brain irradiation must have completed whole-brain radiotherapy and/or stereotactic radiosurgery at least 14 days prior to the start of IMP administration.

•Paediatric patients with either primary brain tumours or extracranial solid tumours with intracranial metastases with one or more intracranial lesions should only be considered for inclusion if largest intracranial lesion is ≤6 cm in longest axis. Consideration should also be given to the intracranial location of the tumour and potential risk should swelling occur. This is because of the class risk of immune checkpoint inhibitors such as atezolizumab causing immune-mediated inflammatory response and 'tumour flare' which may result in acute neurological deterioration.

C. Female patients who are pregnant, breastfeeding or planning to become pregnant during the trial or within five months following their last dose of atezolizumab.

D. History or clinical evidence of current inflammatory lung disease:

  • History of idiopathic pulmonary fibrosis, organising pneumonia (e.g. bronchiolitis obliterans), drug-induced pneumonitis, or idiopathic pneumonitis.
  • Evidence of active pneumonitis on screening chest computed tomography (CT) scan.

E. Active autoimmune disease that requires the use of systemic immunomodulatory therapy (i.e. with disease modifying agents, corticosteroids or immunosuppressive drugs). Replacement therapy for hypothyroidism and adrenal or pituitary insufficiency is acceptable.

F. Ongoing lung pathologies which, in the opinion of the Investigator present a compromise to safety (e.g. active tuberculosis).

G. Systemic immunomodulatory agents within 14 days prior to trial entry (immunostimulatory agents within four weeks). Exceptions to this are:

  • Patients who received acute, low dose systemic immunosuppressant medication or a one-time pulse dose of systemic immunosuppressant medication (e.g. 48 hours of corticosteroids for a contrast allergy) are eligible for the trial.
  • Patients who received corticosteroids for chronic obstructive pulmonary disease (COPD) or asthma equivalent to ≤10 mg prednisolone a day or asthma, or low-dose corticosteroids for orthostatic hypotension or adrenal insufficiency are eligible for the trial.
  • Patients with primary CNS disease can be receiving concurrent treatment with corticosteroids. Patients must be receiving a stable or decreasing dose for ≥14 days for adults and ≥7 days for paediatric patients prior to the screening magnetic resonance imaging (MRI) scan and at the time of drug initiation.
  • Patients who receive physiological doses of steroid replacement (e.g. hydrocortisone) are permitted.

H. Known to be serologically positive (as detected by polymerase chain reaction) for hepatitis B, hepatitis C or human immunodeficiency virus (HIV).

I. History of severe allergic anaphylactic reactions to chimeric, human or humanised antibodies, or fusion proteins including other immune checkpoint inhibitors.

J. Known hypersensitivity to Chinese hamster ovary cell products.

K. Known hypersensitivity to atezolizumab or any of the excipients.

L. Patients who were administered a live, attenuated vaccine within 28 days prior to enrolment, or anticipation of need for such a vaccine during atezolizumab treatment or within five months after the final dose of atezolizumab.

M. Patients with clinically significant pre-existing cardiac conditions, including uncontrolled or symptomatic angina, uncontrolled atrial or ventricular arrhythmias, or NYHA class III or IV congestive heart failure.

Patients with a cerebrovascular event (including stroke or transient ischaemic attacks [TIA]) or cardiovascular event (including acute myocardial infarction [MI]) within three months before the first dose of atezolizumab.

N. Prior allogeneic stem cell or solid organ transplantation on immunosuppression.

O. Prior treatment with the same class of drug unless genetic profile demonstrates a mechanism of resistance known to be potentially sensitive to atezolizumab.

P. Uncontrolled diabetes.

Q. Any clinically significant concomitant disease or condition (or its treatment) that could interfere with the conduct of the trial or absorption of oral medications or that would, in the opinion of the Investigator, pose an unacceptable risk to the patient in this trial.

For paediatric populations multiple measures of QoL will be generated from patient completion of the PedsQL 4.0 (4 measures). The Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean PedsSAUC and 95% credible interval.

Mean change from baseline in the PedsQL 4.0 Standardised Area Under total Scale Score Curve (PedsSAUC) in parents from paediatric participants.
Time Frame: QoL surveys performed prior to inclusion, every 2 cycles (each cycle is 21 days) and at EoT visit (up to 5 years).
For paediatric populations multiple measures of QoL will be generated from patient's parent completion of the PedsQL 4.0 (4 measures). The Summary Score from the questionnaire will be generated at each time point and the area under the curve generated by these scores over time will be calculated and standardised by the time frame. The trial will report the mean PedsSAUC and 95% credible interval.
