Brief summary

This study is aimed to explore the antitumor activity, safety and efficacy profile of cabozantinib in pretreated, advanced RET-rearranged non-small cell lung cancer patients

Interventions

DRUGCabozantinib 20 MG

Cabozantinib will be administered orally at a (starting) dose of 60 mg once daily. The drug is taken continuously over a period of 28 days (4 weeks), which constitutes one treatment cycle. In all subjects, dose reductions (40mg 20mg) and delays to manage toxicity.

Cabozantinib will be administered orally at a (starting) dose of 60 mg once daily. The drug is taken continuously over a period of 28 days (4 weeks), which constitutes one treatment cycle. In all subjects, dose reductions and delays to manage toxicity. Cabozantinib should be taken in fasting condition with no food for at least 2 hours before and 1 hour after taking the tablets. A high fat meal significantly increased the median tmax to 6 hours from 4 hours (fasted). The treatment will be continued until disease progression, intolerable toxicity, patient refusal or Investigator's decision or any criterion for withdrawal from the trial or trial drug is fulfilled.

Inclusion criteria

1. Locally advanced, relapsed or metastatic non-small cell lung cancer - stage IIIB/IV according to 7th International Association for the Study of Lung Cancer (IASLC) classification 2. Ability to understand and willingness to sign informed consent prior to initiation of any study procedures. 3. Pathologically (histology or cytology) confirmed diagnosis of non- small cell lung carcinoma. 4. RET gene rearrangement by local laboratory analysis with an approved standard method (FISH or Next Generation Sequencing Panel). An archival tumor sample must be available for central laboratory confirmation. 5. Male or female and = 18 years of age 6. Life expectancy = 12 weeks 7. Have progressed after or during at least one standard anticancer treatment 8. Have measurable disease as per Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1); clear radiological evidence of disease progression after first-line therapy must be documented; no previous radiotherapy on the only site of measurable or evaluable disease, unless that site had subsequent evidence of progression 9. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 to 1 10. Subjects must have adequate organ function including the following: * Absolute neutrophil count \> 1.5 x 10\^9/L * Platelet count \> 100 x 10\^9/L * Haemoglobin \> 90 g/L * ALT \< 2.5 times the upper limit of normal (ULN) * AST \< 2.5 times ULN * Total bilirubin \<1.5 times ULN * Creatinine \<1.5 times ULN concurrent with creatinine clearance \> 50 ml/min (measured or calculated by Cockcroft and Gault equation, confirmation of creatinine clearance is only required when creatinine is \> 1.5 times ULN) * Lipase \< 2.0 times the upper limit of normal (ULN) 11. Stable medical condition, including the absence of acute exacerbations of chronic illnesses, serious infections, or major surgery within 4 weeks before registration, and otherwise noted in other inclusion/

Exclusion criteria

12. Recovered (i.e., = Grade 1 toxicity) from effects of prior anticancer therapy, except alopecia 13. No radiologic or clinical evidence of acute or chronic pancreatitis 14. For Females: must be postmenopausal (defined as amenhorrea = 12 consecutive months) before the screening visit, or are surgically sterile. If they are of childbearing potential, a negative serum pregnancy test obtained within 3 days before starting study treatment has to be documented; furthermore, patients must agree to adopt 2 effective methods of contraception, at the same time, from the time of signing the informed consent form (ICF) through 4 months after the last dose of study drug. 15. For Males: even if surgically sterilized (i.e. post-vasectomy status) agree to practice effective barrier contraception during the entire study treatment period and through 4 months after the last dose of study drug. 16. Ability to comply with protocol requirement.

Design outcomes

Primary

MeasureTime frameDescription
Response Rate (RR)From the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsExact binomial method will be used to estimate the response rate (CR+PR) and its 95% confidence interval.Proportion of patients presenting Complete Response (CR) or Partial Response (PR) or Stable Disease (SD) based on the Investigator's assessment according to standard RECIST criteria v1.1. Patients with no tumor assessment after baseline will be classified as non-responders.

Secondary

MeasureTime frameDescription
Toxicity (frequency of adverse events)From the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsthe assessment of safety will be based mainly on the frequency of adverse events; toxicity will be measured according to NCI Common Toxicity Criteria Adverse Event (CTCAE), version 4.03.
Progression-Free Survival (PFS)From the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsPFS will be calculated from the first treatment intake to the date of progressive disease, or death.
Overall survival (OS)From the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsOS will be calculated from the first treatment intake to death from any cause.
Duration of response (DORFrom the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsDOR will be calculated from the first treatment intake to the date of disease progression or death.
Disease Control Rate(DCR)From the start of treatment ( Baseline) to the progression of Disease (PD) or trial discontinuation whichever occurs first, assessed up to 24 monthsDCR will be measured as the sum of complete and partial responses + stable disease.

Other

MeasureTime frameDescription
RET aberrationOn the start of treatment (Baseline) and through study completion, an average of 1 yearDetection of RET aberration on DNA extracted from circulating tumor cells (CTCs) isolated in blood at baseline (optional)
RET-rearrangment on tumor tissueAt the start of treatment (baseline)Archival tumor tissue (FFPE tumor block or 7-10 unstained slides) will be assessed for determination of RET-rearrangment on tumor cells by using A FISH evaluation of the translocation will be performed using a break-apart probe for the 10p11 locus.
