简要总结
A research study to evaluate the activity of alectinib for the Treatment of pretreated patients with advanced NSCLC that have confirmed RETrearrangement.
详细描述
The trial is investigating the efficacy of alectinib in patients with advanced stage RET-rearranged NSCLC, treated with at least one platinum based systemic chemotherapy regimen. Preclinical studies have shown that alectinib, a highly selective next generation ALK inhibitor, has potent anti-tumour activity in RET-rearranged NSCLC. Therapeutically, several multiple kinases inhibitors, are potentially able to inhibit RET kinase function, which has been tested in several unselected NCSLC trials. However, those result were negative and none of the tested drugs was approved for lung cancer treatment.
The ALERT-lung trial is a single arm, phase II trial with the primary objective to assess the efficacy of alectinib in terms of best overall response (OR) assessed by RECIST v1.1 in selected NSCLC patients with RET rearrangement. The secondary objectives are to evaluate secondary measures of clinical efficacy including disease control, progression-free survival (PFS), and overall survival (OS) as well as to assess safety and tolerability of the treatment and to describe the association of primary and secondary outcomes with tumour characteristics.
Alectinib is administered orally, 600 mg, twice per day, until progression, refusal or unacceptable toxicity. Trial treatment may also continue beyond progression, with physician and patient agreement, for as long as the patient may still derive clinical benefit. A total sample size of 44 patients is required.

- •Sexually active men and women of childbearing potential must use an effective contraceptive method (intrauterine devices without hormones, bilateral tubal occlusion, vasectomized partner or total abstinence) during the trial treatment and for a period of at least 3 months following the last dose of alectinib.
- •Recovered from any previous therapy related toxicity to Grade ≤1 at date of enrolment (except for recovery to Grade ≤2 of alopecia, fatigue, creatinine increased, lack of appetite or peripheral neuropathy)

研究组 & 干预措施
Trial treatment
Alectinib is administered orally, 600 mg, twice per day (1200 mg per day) until progression, refusal or unacceptable toxicity.
Trial treatment may also continue beyond progression, with physician and patient agreement, for as long as the patient may still derive clinical benefit as per investigator decision.
干预措施: Alectinib (Drug)
结局指标
主要结局
Best Overall Response (BOR)
时间窗: Evaluated from enrollment through study completion, up to a maximum of 28 months.
Best overall response (OR = CR or PR), per investigator assessment. OR was determined using the Response Evaluation Criteria in Solid Tumors (RECIST v1.1). OR is defined as the best overall response \[Complete Response (disappearance of all target and non-target lesions, no new lesions) or Partial Response (at least a 30% decrease in the sum of the longest diameter of target lesions taking as reference the baseline sum of diameters, no measurable increase in a non-target lesion, no new lesions)\] across all assessment points. Radiological tumour assessments were performed using CT scans.
次要结局
- Disease Control at 24-weeks(From first documented response (CR, PR, SD, non-CR/non-PD) to 24 weeks or first documented progression or death from any cause, whichever came first, assessed every 8 weeks (±4 days).)
- Progression-free Survival (PFS)(Evaluated from enrollment through study completion, up to a maximum of 28 months.)
- Overall Survival (OS)(Evaluated from enrollment through study completion, up to a maximum of 28 months.)
- Number of Patients Experienced Adverse Events(Evaluated from enrollment through study completion, up to a maximum of 28 months.)
