Cancer Research UK30 enrolled

Overview

This clinical trial is looking at a drug called entrectinib. Entrectinib is approved as standard of care treatment for adult patients with non-small cell lung cancer (NSCLC) which have a particular molecular alteration called ROS1-positive, and patients 12 years old or above with solid tumours which have another type of change in the cancer cells. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Investigators now wish to find out if it will be useful in treating patients with other cancer types which have the same molecular alteration (ROS1-positive). 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.

DETERMINE Treatment Arm 03 (entrectinib) aims to evaluate the efficacy of entrectinib in ROS1 gene fusion-positive rare\* adult, paediatric and teenage/young adult (TYA) cancers and in common cancers where a ROS1 mutation or amplification 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 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 patient based on molecularly-defined cohorts. Screening: Consenting patients undergo biopsy and collection of blood samples for research purposes. Treatment: Patients will receive entrectinib until disease progression without clinical benefit, unacceptable adverse events (AEs) or withdrawal of consent. Patients will also undergo collection of blood samples at various intervals while receiving treatment and at the end of treatment visit (EoT). After completion of study treatment, patients are followed up every 3 months for 2 years THE DETERMINE TRIAL MASTER (SCREENING) PROTOCOL: Please see DETERMINE Trial Master (Screening) Protocol record (NCT05722886) for information on the DETERMINE Trial Master Protocol and applicable documents.

An OR is defined as the confirmed occurrence of either a Complete Response (CR) or Partial Response (PR) according to Response Evaluation Criteria in Solid Tumours (RECIST) Version 1.1 criteria (or immune related \[ir\]-RECIST or standard imaging criteria for specific disease e.g. Response Evaluation in Neuro Oncology criteria \[RANO\]). In patients with leukaemia, OR will be defined as the occurrence of CR, CRi (CR with incomplete neutrophil recovery) or CRp (CR with incomplete platelet recovery). The trial will report the proportion of patients with an OR and 95% credible interval.

Time frame: Disease assessments to be performed up to 24 weeks from the start of trial treatment.

Durable Clinical Benefit (DCB)

DCB is defined as the absence of disease progression for at least 24 weeks from the start of trial treatment according to RECIST Version 1.1 criteria (or ir-RECIST or standard imaging criteria for specific disease e.g. RANO criteria) and, where relevant (e.g. for haematological malignancies), by standard bone marrow response assessment criteria. Alternative definitions of DCB based on different time points may be pre-specified for particular sub-cohorts if 24 weeks is not clinically relevant. The trial will report the proportion of patients with a DCB and 95% credible interval.

Time frame: Disease assessments to be performed up to 24 weeks from the start of trial treatment.

Secondary Outcomes

Duration of response (DR)

DR is defined as the time from the date of the first confirmed CR or PR according to RECIST 1.1 (or ir-RECIST or standard imaging criteria for specific disease e.g. RANO criteria) to the date of disease progression. The trial will report the median DR and 95% credible interval.

Time frame: Disease assessment every 2 cycles of entrectinib (each cycle is 28 days) and at EoT. After 24 weeks, it can be done every 12 weeks, on discussion with Sponsor. Follow-up visits are every 3 months after last dose of entrectinib for up to 2 years.

Best percentage change in sum of target lesion / index lesion diameters (PCSD)

PCSD is defined as the greatest decrease or least increase in the sum of target lesion diameters (RECIST) or index lesion diameters (irRECIST) as a percentage compared to the baseline measurement. The trial will report the mean PCSD and 95% credible interval.

EORTC-QLQ-C30 Standardised Area Under Summary Score Curve (QLQSAUC) in adult patients.

For adult populations, multiple measures of Quality of Life (QoL) will be generated from patient completion of the European Organisation for Research and Treatment of Cancer QLQ-C30 (EORTC-QLQ-C30) questionnaire (15 measures). For each patient 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 QLQSAUC and 95% credible interval.

Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).

EQ-5D Standardised Area Under Index Value Curve (EQ5DSAUC) in adult patients

For adult populations, two measures of QoL will be generated from patient completion of the EQ-5D-5L questionnaire. For each measure, scores based on responses 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 EQ5DSAUC and 95% credible interval.

Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).

Mean change from baseline in the PedsQL 4.0 Standardised Area Under total Scale Score Curve (PedsSAUC) in paediatric patients

For paediatric populations multiple measures of QoL will be generated from patient completion of the PedsQL 4.0 (4 measures and a Total Scale Score). 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.

Time frame: QoL surveys performed prior to inclusion, every cycle (each cycle is 28 days) and at EoT visit (up to 5 years).
