A Randomized, Double-blind, Placebo-controlled, Phase 2 Clinical Trial of Alisertib (MLN8237) in Combination With Paclitaxel Versus Placebo in Combination With Paclitaxel as Second Line Therapy for Small Cell Lung Cancer (SCLC).


Brief Summary
This is a two-arm, randomized, double-blind, placebo-controlled, multicenter, phase 2 study designed to is to determine if the combination treatment can improve progression free survival (defined as the time from the date of randomization to the date of first documentation of disease progression or death, whichever occurs first) when compared with placebo + paclitaxel.

Detailed Description
The drug tested in this study is called alisertib. Alisertib is being tested to treat people who have Small Cell Lung Cancer (SCLC). This study determined the safety and efficacy for alisertib when given twice a day along with paclitaxel. This open label study enrolled 178 patients. Participants were randomly assigned (by chance, like flipping a coin) to one of the two treatment groups—which remained undisclosed to the patient and study doctor during the study (unless there is an urgent medical need) and participants were stratified at baseline as to whether brain mets were present or not; whether they were sensitive to prior therapy or were relapsed/refractory to prior therapy; and by world region: - Alisertib 40 mg + Paclitaxel 60 mg/m^2 - Paclitaxel 80 mg/m^2 + Placebo (dummy inactive pill) - this is a tablet that looks like the study drug but has no active ingredient All participants received treatment until their disease progressed or they experienced unacceptable alisertib-related toxicity. This multi-center trial was conducted world-wide. The overall time to participate in this study was approximately up to 22 months. Participants made multiple visits to the clinic, and were contacted by telephone every month for 6 months after the end of treatment (EOT) for follow-up assessment of progression free survival and for overall survival every 2 months until death, study closure, or 14 months after randomization of the last participant.


Phase 2 - takes the treatment one step further, assessing the activity of a particular therapy in a disease, often building upon leads from the Phase I trial. While patients are generally required to be previously untreated, participation in a Phase II trial doesn't usually preclude the patient from getting the standard treatment after they've received the investigational agent. At best they are allowed to get a new drug they wouldn't be able to get otherwise that may turn out to be better for their disease.

Inclusion and Exclusion Criteria

  • Inclusion Criteria Each participant must meet all the following inclusion criteria to be enrolled in the study:
  • Male or female participants ≥ 18 years old.
  • Have a pathologically (histology or cytology) confirmed diagnosis of SCLC.
  • Have received and progressed after a platinum-based standard chemotherapy regimen for first line treatment of SCLC, either limited stage (LS) or extensive stage (ES).
  • Have measurable disease within ≤ 2 weeks before randomization. Clear radiographic evidence of disease progression after initial therapy should have been documented.
  • Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0 or 1 (PS 0-1).
  • Participants with treated brain metastases (surgery, whole or stereotactic brain radiation) are allowed provided the lesions have been stable for at least 2 weeks and the participant is off steroids or is on a stable dose of steroids. Participants should be without neurologic dysfunction that would confound the evaluation of neurological and/or other AEs. Exclusion Criteria Participants meeting any of the following exclusion criteria are not to be randomized to treatment:
  • Any prior therapy for second-line treatment of SCLC.
  • Participants who relapsed ≥ 180 days after their response to first-line treatment.
  • Prior treatment with an Aurora A specific-targeted or pan-Aurora-targeted agent, including alisertib, or any other investigational agent.
  • Prior treatment with paclitaxel or any other taxane agent.
  • Known hypersensitivity to Cremophor® EL, paclitaxel, or its components.
  • Any comorbid condition or unresolved toxicity that would preclude administration of alisertib or weekly paclitaxel.
  • Prior history of ≥ Grade 2 neurotoxicity that is not resolved to ≤ Grade 1.
  • Participants with symptomatic and/or progressive brain metastases or with carcinomatous meningitis.
  • Treatment with clinically significant enzyme inducers within 14 days prior to the first dose of alisertib and during study conduct. Major prohibited enzyme inducers include: phenytoin, carbamazepine, phenobarbital, rifampin, rifabutin, rifapentine, and St. John's wort.
  • Inability to swallow alisertib or other orally administered medications.
  • Requirement for administration of proton pump inhibitor (PPI), H2 antagonist, or pancreatic enzymes.
  • Diagnosed with or treated for another malignancy within 2 years before the first dose of study drug, or previously diagnosed with another malignancy and have any evidence of residual disease.
  • Other severe acute or chronic medical or psychiatric condition(s) per protocol.
  • History of myocardial infarction, unstable symptomatic ischemic heart disease, uncontrolled hypertension despite appropriate medical therapy, any ongoing cardiac arrhythmias of Grade > 2, thromboembolic events (eg, deep vein thrombosis, pulmonary embolism, or symptomatic cerebrovascular events), or any other cardiac condition (eg, pericardial effusion or restrictive cardiomyopathy) within 6 months before receiving the first dose of study drug.
  • Known history of human immunodeficiency virus (HIV) infection, hepatitis B or hepatitis C.
  • Surgery within 3 weeks (or 2 weeks for a minor surgery) before study enrollment and not fully recovered to baseline or to a stable clinical status.
  • Participants who are pregnant, lactating, or do not agree to use effective methods of contraception during the study treatment period through 6 months after the last dose of study drug per protocol.
