A Phase 2 interventional study of Repotrectinib in NSCLC, Brain Metastases and ROS1 Gene Rearrangement, sponsored by MedSIR. Recruiting at 17 sites in 3 countries. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-09-09.
Sponsored by MedSIR · Phase 2, Interventional, and Treatment
REPOSE is a phase II clinical trial exploring the safety and efficacy of repotrectinib in patients with non-small cell lung cancer (NSCLC) characterized by the presence of brain metastasis (BM) and whose tumors have mutated ROS proto-oncogene 1, receptor tyrosine kinase (ROS1) gene.
REPOSE is an international multicenter, open-label, single arm phase II clinical trial designed to evaluate the efficacy of repotrectinib in patients with ROS1-positive NSCLC with BM.
Upon meeting all selection criteria, a total of 20 participants confirmed ROS1 rearrangement will be enrolled. Participants who have received prior chemotherapy, immunotherapy or other non-ROS1 tyrosine kinase inhibitor (TKI) are eligible.
Patients will continue study treatment until end of treatment (EoT) defined as the date of disease progression, death, or discontinuation from the study treatment for any other reason. After study treatment discontinuation, all participants will undergo a safety visit (at 28 ± 7 days after last treatment dose) in order to follow up toxicities and changes in concomitant medication. Patients discontinuing the study treatment at any time will enter a post-treatment follow-up period during which survival and subsequent anticancer therapy information will be collected every 3 months (± 7 days) from the safety visit until death, lost to follow-up, elective withdrawal from the study, or the end of study (EoS), whichever occurs first. Patients who discontinue treatment without evidence of disease progression will be also followed for tumor assessments until documented progression, elective withdrawal from the study, the start of new anti-cancer treatment, or the EoS.
EoS is estimated to occur 13 months after the last participant is included (LPI), unless premature termination of the Study. EoS is defined as the last data collection point in the Study (which can be a clinic visit or a telephone call), unless premature termination of the Study.
The main objective of REPOSE study is to determine the efficacy of repotrectinib at any timepoint during the study period as determined locally by best central nervous system (CNS) response, that is in terms of intracranial objective response rate (IC-ORR).

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Patients will be included in the study only if they meet all the following criteria:
No indication for immediate local therapy (neurosurgery, brain radiotherapy) of brain metastases per local investigator.
Note: in case of immediate local therapy is needed, the study's medical monitor should be consulted.
Patient has adequate bone marrow, liver, and renal function:
I. Hematological (without , red blood cell transfusion, and/or granulocyte colony-stimulating factor support within 28 days before first study treatment dose): White blood cell (WBC) count > 3.0 x 109/L, (ANC) ≥ 1.5 x 109/L, platelet count ≥ 100.0 x109/L, and ≥ 8.0 g/dL (≥ 4.96 mmol/L).
II. Hepatic: Total ≤ 1.5 times (ULN) (≤ 3 in patients with liver metastases or know history of Gilbert's disease); alkaline phosphatase (ALP) ≤ 2.5 times ULN; (AST) and alanine transaminase (ALT) ≤ 3 times ULN (≤ 5 in patients with liver metastases); (INR) \< 1.5.
III. Renal: serum creatinine ≤ 1.5 x ULN or ≥ 40 mL/min/1.73 m2 based on Cockcroft-Gault estimation for patients with creatinine levels above institutional normal.
Women of (WOCBP) who are sexually active with a non-sterilized male partner must have a negative serum pregnancy test within 14 days before study treatment initiation. In addition, they must agree to use one highly effective method of from the time of screening until 2 months after the last dose of study treatments. Female patients must refrain from egg cell donation and breastfeeding during this same period.
Note: Due to a potential loss of effectiveness of hormonal contraceptives caused by interaction with study intervention, if WOCBP use hormonal contraceptives (including oral hormonal contraceptives), they must use either another form of non-hormonal highly effective contraception or a reliable barrier method.
Exclusion Criteria:
Any patient meeting ANY of the following criteria will be excluded from the study:
Any of the following cardiac criteria:
I. Mean resting interval ( interval measured from the onset of the QRS complex to the end of the T wave) for heart rate (QTc) > 470 msec obtained from 3 ECGs, using the screening clinic ECG machine-derived QTc value.
II. Any abnormalities in rhythm, conduction or morphology of resting ECG (e.g., complete left bundle branch block, third degree heart block, second degree heart block, PR interval > 250 msec).
III. Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome, or any concomitant medication known to prolong the QT interval.
Presence or history of any other primary other than NSCLC within 5 years prior to enrollment into the study.
Note: Patients with a history of adequately treated basal or squamous cell carcinoma of the skin or any adequately treated in situ carcinoma may be included in the study.
Current use or anticipated need for drugs that are known to be strong Cytochrome P450, family 3, subfamily A () inhibitors or inducers.
Note: midazolam requires diligent monitoring in situations where there is an unprecedented necessity for co-administration. These cases should be discussed with the study's medical monitor.
Patients requiring concomitant use of chronic systemic (intravenously [IV] or oral) corticosteroids at doses higher than 8 mg dexamethasone per day or other medications except for managing adverse events (AEs); (inhaled steroids or intra articular steroid injections are permitted in this study).
Note: The use of stable corticosteroid therapy in patients with should be discussed with the Sponsor's Medical Monitor.
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).
Your pathology report is the document that shows this.
Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).
Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.
Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.
Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.
Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.
It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.
The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Blood tests of how long blood takes to clot. The INR is the prothrombin time (PT) put on a common scale; about 1 is usual for someone not taking a blood thinner.
Criteria often make an exception for people on a blood thinner such as warfarin, whose INR is raised on purpose.
How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.
GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².
Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.
The US National Cancer Institute’s scale of how severe an adverse event is — any unwanted medical event during a study, such as a symptom, an illness or an abnormal test result, whether or not a treatment caused it. Whether it did is judged separately.
“Side effects of earlier treatment resolved to grade 1 or less” means they have settled to mild or gone.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
On an ECG, the QT interval is the time the heart’s lower chambers take to activate electrically and recover in each beat. QTc is that time adjusted for heart rate (QTcF by Fridericia’s formula, QTcB by Bazett’s). Some medicines lengthen it, and a long QTc can raise the risk of a dangerous heart rhythm.
The study may name a correction formula and a limit in milliseconds, often around 450–480.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The New York Heart Association’s four classes of how much heart failure limits physical activity.
Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.
A “mini-stroke”: temporary stroke-like symptoms caused by reduced blood flow to part of the brain, spinal cord or eye, without signs of a new stroke on a scan.
Stroke symptoms need emergency care at once, even if they go away.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.
Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Progression-Free Survival (PFS)
To assess the PFS, defined as the period from treatment initiation to the first occurrence of disease progression or death from any cause, whichever occurs first, determined locally per RANO-BM criteria for IC lesions and RECIST criteria v.1.1 for EC and overall lesions.
Time frame: From date of inclusion until the date of first documented progression or date of death from any cause or treatment discontinuation from any other reason, whichever came first, assessed through study completion, an average of 13 months.
Overall Survival (OS)
To determine the OS, defined as the period from treatment initiation to death from any cause, determined locally by the investigator.
Time frame: From date of inclusion until the date of first documented progression or date of death from any cause or treatment discontinuation from any other reason, whichever came first, assessed through study completion, an average of 13 months.
Neurologic function
To assess the patient neurologic function with the Neurologic Assessment in Neuro-Oncology (NANO) scale
Time frame: From date of inclusion until the date of first documented progression or date of death from any cause or treatment discontinuation from any other reason, whichever came first, assessed through study completion, an average of 13 months.
Quality of life (QoL) with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-30)
To evaluate changes from baseline and during repotrectinib treatment in terms of patient-reported outcome (PRO) assessments of QoL and treatment-related symptoms as measured by EORTC QLQ-C30 scale. EORTC QLQ-C30 scale aims to measure cancer patients' physical, psychological and social functions. Scale and single items are transformed into scores ranging from 0 to 100. A high score for a functional scale represents a high level of functioning, whereas a high score for a symptom scale/single item represents a high level of symptomatology.
Time frame: From date of inclusion until the date of first documented progression or date of death from any cause or treatment discontinuation from any other reason, whichever came first, assessed through study completion, an average of 13 months.
QoL with the brain cancer specific questionnaire (QLQ-C20).
To evaluate changes during repotrectinib treatment in terms of PRO assessments of QoL and treatment-related symptoms as measured by EORTC QLQ-C20 scale. EORTC QLQ-BN20 brain specific tool aims to measure the effects of brain tumors and its treatment on symptoms, functions and health-related quality of life. Scale and single items are transformed into scores ranging from 0 to 100. A high score for a functional scale represents a high level of functioning, whereas a high score for a symptom scale/single item represents a high level of symptomatology.
Time frame: From date of inclusion until the date of first documented progression or date of death from any cause or treatment discontinuation from any other reason, whichever came first, assessed through study completion, an average of 13 months.
Safety and tolerability
To evaluate the safety and toxicity profile of treatment with of repotrectinib as per National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0.
Time frame: Through study completion, an average of 13 months.
Exploratory endpoint: Genetic studies using blood samples to investigate the potential association with clinical outcomes
Gene expression profiling analyses performed on blood samples to investigate the potential association with clinical outcomes.
Time frame: Through study completion, an average of 13 months.
Exploratory endpoint: ROS1 gene expression analysis using baseline tissue samples to investigate the potential association with clinical outcomes
ROS1 gene expression analysis performed on baseline tumor tissue samples to investigate the potential association with clinical outcomes.
Time frame: Through study completion, an average of 13 months.
Exploratory endpoint: Analysis of medical imaging to identify potential biomarkers associated with clinical outcomes
Analysis of oncological biomarkers, such as growth rate of tumor derived by tumor growth rate modeling or tumor heterogeneity according to quantitative estimation through radiomics, may be performed on radiological images to investigate the potential association with clinical outcomes.
Time frame: Through study completion, an average of 13 months.
Started Jun 2025 (actual). Primary completion is estimated for Mar 2027, 21 months after the start.
Of 208 non-industry phase 2 interventional studies under Brain Neoplasms, half reached primary completion within 67 months of starting (the median), counting those still running; a quarter within 43 and three quarters within 100. This study's planned 21 months is below that.
Counting every sponsor, half of 252 studies reached it within 61 months; a quarter within 38 and three quarters within 98.
