What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 30 participants in total. It began in 2024-11-19 with a primary completion date of 2029-10.

Brief Summary

This clinical trial is looking at a drug called capmatinib. Capmatinib is approved as standard of care treatment for adult patients with certain types of lung cancer. This means it has gone through clinical trials and been approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Capmatinib works in patients with lung cancer with a particular mutation in their cancer known as a METex14 skipping mutation. Investigators now wish to find out if it will be useful in treating patients with other cancer types which have the same mutation or other specific mutations or changes which take place in the MET gene. 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.

Eligibility Criteria

THE PATIENT MUST FULFIL THE ELIGIBILITY CRITERIA WITHIN THE DETERMINE MASTER PROTOCOL (NCT05722886) AND WITHIN THE TREATMENT ARM 06 (CAPMATINIB) OUTLINED BELOW\* \*When capmatinib-specific inclusion/exclusion criteria or precautions below differ from those specified in the Master Protocol, the capmatinib-specific criteria will take precedence. Inclusion criteria: A. Confirmed diagnosis of a MET-positive malignancy using an analytically next-generation sequencing method (METex14 skipping, MET amplification, MET fusion, or MET activating mutation). B. Adult patients ≥18 years old. C. Women of childbearing potential are eligible, provided that they meet the following criteria: * Have a negative serum or urine pregnancy test before enrolment, and * Agree to use one form of highly effective birth control method (a method that can achieve a failure rate of \<1% when used consistently and correctly), such as: I. combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation \[oral, intravaginal or transdermal\]) II. progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, or implantable) III. intrauterine device (IUD) IV. Intrauterine hormone-releasing system (IUS) V. bilateral tubal occlusion VI. vasectomised partner VII. sexual abstinence Effective from the first administration of capmatinib, throughout the trial and for seven days after the last administration of capmatinib. D. Male patients with partners who are women of childbearing potential are eligible provided that they agree to the following, from first administration of capmatinib, throughout the trial and for seven days after the last administration of capmatinib: * Agree to take measures not to father children by using a barrier method of contraception (e.g. condom) or sexual abstinence. * Non-vasectomised male patients with partners who are women of childbearing potential must also be willing to ensure that their partner uses a highly effective method of contraception, as in criterion C above. * Male patients with pregnant or lactating partners must be advised to use barrier method contraception (for example, condom) to prevent drug exposure of the foetus or neonate. All male patients must refrain from donating sperm for the same period. E. Patients must be able and willing to undergo a fresh biopsy at baseline and blood samples for translational research. Note that for patients with haematological malignancies or neuroblastomas, blood, bone marrow aspiration and/or trephine or lymph node biopsy samples may be taken. F. Adequate organ function as per haematological and biochemical indices within the ranges defined in the protocol. These measurements should be performed to confirm the patient's eligibility. Exclusion criteria: A. Diagnosis of NSCLC with METex14 skipping mutation or MET amplification. B. Prior treatment with a selective MET inhibitor or HGF-targeting therapy unless genetic profile demonstrates a mechanism of resistance known to be potentially sensitive to capmatinib. C. Carcinomatous meningitis. D. Presence or history of additional malignant disease that has been diagnosed and/or required therapy within the past three years. Exceptions to this exclusion include: completely resected basal cell and squamous cell skin cancers, and completely resected carcinoma in situ of any type. E. Presence or history of interstitial lung disease (ILD) and/or interstitial pneumonitis, including clinically significant radiation pneumonitis (i.e., affecting activities of daily living or requiring therapeutic intervention) and evidence of active pneumonitis on screening chest computed tomography (CT) scan. Prior localised radiotherapy related pneumonitis is permitted if resolved and off steroids and asymptomatic for at least six months. F. Clinically significant, uncontrolled heart disease such as: * Unstable angina within three months prior to screening * Myocardial infarction within three months prior to screening * History of documented congestive heart failure (New York Heart Association functional classification III-IV) * Uncontrolled hypertension defined by a systolic blood pressure ≥160 mm Hg and/or diastolic blood pressure ≥100 mm Hg, with or without antihypertensive medication. Initiation or adjustment of antihypertensive medication(s) is allowed prior to screening. Patients with a cerebrovascular event (including stroke or transient ischaemic attack \[TIA\]) within three months before screening. • Patients with primary CNS tumours may be considered unless intra-tumoural bleeding has occurred within two weeks of the first dose of capmatinib, and patients with punctate CNS haemorrhages \<3 mm may be considered. G. History or current diagnosis of electrocardiogram (ECG) abnormalities indicating significant risk of safety for patients participating in the trial such as: * Concomitant clinically significant cardiac arrhythmias (atrial and ventricular), e.g., sustained ventricular tachycardia, and clinically significant second or third degree AV block without a pacemaker * History of familial long QT syndrome or known family history of Torsades de Pointes * Resting QTcF (Corrected QT interval by Fridericia formula) ≥450 msec (male) or ≥460 msec (female) at screening ECG (as a mean of triplicate ECG) H. Major surgery (e.g., intra-thoracic, intra-abdominal or intra-pelvic) within four weeks prior to starting trial treatment (two weeks for resection of brain lesions) or patients who have not recovered from side effects of such procedure. Video-assisted thoracic surgery (VATS) and mediastinoscopy will not be counted as major surgery and patients can be enrolled in the trial at least one week after the procedure. I. Patients receiving treatment with strong inducers of cytochrome P450 (CYP) 3A that cannot be discontinued at least one week prior to the start of treatment with capmatinib and for the duration of the trial. J. Any clinically significant concomitant disease or condition (or its treatment) that could interfere with the conduct of the trial (including absorption of oral medications) that would, in the opinion of the Investigator, pose an unacceptable risk to the patient in this trial. K. Any impairment of gastrointestinal (GI) function or GI disease that may significantly alter the administration or absorption of capmatinib (e.g., Crohn's disease, ulcerative diseases, uncontrolled nausea, vomiting, diarrhoea, malabsorption syndrome or short gut syndrome). Unable to swallow capmatinib intact, without chewing or crushing the tablets (as per the dosing schedule). L. Active infections including, but not limited to, hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). Screening for known chronic conditions is not required. Patients with known serological evidence of chronic HBV or HCV infection whose disease is controlled under antiviral therapy according to local regulation are eligible. Patients with history of testing positive for human immunodeficiency virus (HIV) infection are eligible provided the each of the following conditions are met: * CD4 count ≥350/μL; * undetectable viral load; * receiving antiretroviral therapy (ART) that does not interact with IMP (patients should be on established ART for at least four weeks); and * no HIV/ acquired immune deficiency syndrome-associated opportunistic infection in the last 12 months. M. Known hypersensitivity to any of the excipients of capmatinib. N. Patients with symptomatic central nervous system (CNS) metastases who are neurologically unstable or have required increasing doses of steroids within the two weeks prior to trial entry to manage CNS symptoms. Primary brain or CNS malignancies are allowed providing the patient is clinically stable (if corticosteroids are required, they must be at a stable or decreasing dose for at least 14 days prior to Cycle 1 Day 1). If patients are on corticosteroids for endocrine deficiencies or tumour-associated symptoms other than CNS related, the dose must have been stabilised (or decreasing) for at least five days before Cycle 1 Day 1. O. Patients receiving treatment with any enzyme-inducing anticonvulsant that cannot be discontinued at least one week before first dose of capmatinib, and for the duration of the trial. Patients on non-enzyme-inducing anticonvulsants are eligible. P. Female patients who are pregnant, breastfeeding or planning to become pregnant during the trial or for seven days following their last dose of capmatinib. Q. Patients who were administered a live, attenuated vaccine within 28 days prior to enrolment, or anticipation of need for such a vaccine during capmatinib treatment or within six months after the final dose of capmatinib.
