Clinical Trial Summary

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.


Description:

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 approximately 13 months after the last patient included in the study initiates repotrectinib treatment, unless consent withdrawal, patient is lost to follow-up, death, or premature termination of the study. EoS is defined as the last data collection point at the last participant's safety visit and will occur after the study treatment termination of the last patient in 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).

Patients with confirmed ROS1 rearrangement. Prior to study enrollment, patients must have had confirmation of ROS1 rearrangement, which should have been determined locally by a certified laboratory using methods such as fluorescent in situ hybridization (FISH), next generation sequencing (NGS), quantitative PCR (qPCR), or immunohistochemistry (IHC). 9. Measurable disease according to RANO-BM criteria, with at least one measurable brain lesion of =10 mm on T1-weighted, gadolinium-enhanced magnetic resonance imaging (MRI). 10. Eastern Cooperative Oncology Group (ECOG) performance status of = 2. 11. Minimum life expectancy of = 6 weeks at screening. 12.

II. Hepatic: Total bilirubin = 1.5 times upper limit of normal (ULN) (= 3 in patients with liver metastases or know history of Gilbert's disease); alkaline phosphatase (ALP) = 2.5 times ULN; aspartate transaminase (AST) and alanine transaminase (ALT) = 3 times ULN (= 5 in patients with liver metastases); international normalized ratio (INR) < 1.5. III.

Women of childbearing potential (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 birth control 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. 19. Male participants who are sexually active with a WOCBP partner must be surgically sterile or using an acceptable method of contraception from the time of screening until 4 months after the last administration of the study drug. Male participants must not donate or bank sperm during this same period. 20. Patient must be accessible for treatment and follow-up. Exclusion Criteria: Any patient meeting ANY of the following criteria will be excluded from the study: 1. Major surgery within four weeks of the start of treatment. 2. Type I leptomeningeal disease per ESMO-EANO guidelines. 3. Any of the following cardiac criteria: I. Mean resting corrected QT interval (ECG 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 clinically important 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).

Peripheral neuropathy grade = 2. 8. History of extensive, disseminated, bilateral, or presence of NCI CTCAE grade 3 or 4 interstitial fibrosis or interstitial lung disease (ILD) including a history of pneumonitis, hypersensitivity pneumonitis, interstitial pneumonia, ILD, obliterative bronchiolitis, and pulmonary fibrosis. Patients with a history of prior radiation pneumonitis are not excluded. 9. Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may increase the risk associated with study participation or study drug administration, or that may interfere with the interpretation of study results and, in the judgment of the Investigator, would make the patient inappropriate for entry into this study or could compromise the protocol objectives in the opinion of the Investigator. 10. Presence or history of any other primary malignancy 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. 11. Current use or anticipated need for drugs that are known to be strong Cytochrome P450, family 3, subfamily A (CYP3A) 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. 12. Patients requiring concomitant use of chronic systemic (intravenously [IV] or oral) corticosteroids at doses higher than 8 mg dexamethasone per day or other immunosuppressive 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 brain metastases should be discussed with the Sponsor's Medical Monitor.
