Clinical Trial Summary

LEE011 is a small molecule inhibitor of CDK4/6. LEE011 has demonstrated in vitro and in vivo activity in both tumor models. The primary purpose of this study was to determine the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE) in pediatric patients and to delineate a clinical dose to be used in future studies. This study was also to have assessed the safety, tolerability, PK and preliminary evidence of antitumor activity of LEE011 in patients with MRT or neuroblastoma.

Description:

Due to lack of efficacy, enrollment in the study was stopped at the end of dose escalation (sites were notified of the early enrollment halt on 7-Aug-2014) and the dose-expansion part was not conducted. Due to halted enrollment and/or lack of complete responses (CR) and partial responses (PR), efficacy analysis was only performed in terms of TTP for the patients treated during the dose-escalation part at the maximum tolerated dose (MTD) and recommended dose expansion (RDE).

• Est. primary completion date: June 29, 2017
• Accepts healthy volunteers: No
• Gender: All
• Age group: 1 Year to 21 Years

Eligibility

Inclusion Criteria:

• Confirmed diagnosis of MRT or, neuroblastoma or in dose escalation part, other tumors with documented evidence of D-cyclin-CDK4/6-INK4a-Rb pathway abnormalities (dose escalation part only),

• Patients with CNS disease should be on stable doses of steroids for at least 7 days prior to first dose of LEE011 with no plans for escalation.

• In expansion part, patients must have at least one measurable disease as defined by RECIST v1.1.

• Patients must have a Lansky (= 16 years) or Karnofsky (> 16 years) score of at least 50.

Exclusion Criteria:

• Prior history of QTc prolongation or QTcF > 450 ms on screening ECG.

• Patients with the following laboratory values during screening:

• Serum creatinine > 1.5 x upper limit of normal (ULN) for age

• Total bilirubin >1.5 x ULN for age

• Alanine aminotransferase (ALT)/serum glutamic pyruvic transaminase (SGPT) > 3 x ULN for age; aspartate aminotransferase (AST)/serum glutamic oxaloacetic transaminase(SGOT) > 3 x ULN for age except in patients with tumor involvement of the liver who must have AST/SGOT and ALT/SGPT = 5 x ULN for age. For the purpose of this study, the ULN for SGPT/ALT is 45 U/L.

• Patients who are currently receiving treatment with agents that are metabolized predominantly through CYP3A4/5 and have a narrow therapeutic window and/or agents that are known strong inducers or inhibitors CYP3A4/5 are prohibited. In particular, enzyme-inducing antiepileptic drugs (EIAEDs).

• Other severe acute or chronic medical or psychiatric condition or laboratory abnormality that may interfere with the interpretation of study results, and in the judgment of the investigator would make the patient inappropriate for the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence Rate of Dose Limiting Toxicities (DLTs) by Primary System Organ Class, Preferred Term and Treatment	A DLT was defined as an AE or clinically significant abnormal laboratory value assessed as unrelated to disease, disease progression, inter-current illness, or concomitant medications that occurred within the first 28 days of treatment with LEE011 and met any of the predefined criteria. For the purpose of dose-escalation decisions, DLTs were considered and included in the Bayesian Logistic Regression Model (BLRM). Patients who did not experience DLT during the first cycle were considered to have had sufficient safety evaluations if they were observed for = 28 days following the first dose and were considered to have had enough safety data to conclude that a DLT did not occur. Patients who did not meet these minimum safety evaluation requirements were regarded as ineligible for the DDS. A patient with multiple DLTs within a primary system organ class is counted only once in the total row.	cycle 1 = 28 days (from the time of first dose)
Secondary	Overall Response Rate	This analysis was not done as there were no responders.	Every 2 cycles (cycle = 28 days) up to end of treatment, the maximum time a patient was on study was 1311 days
Secondary	Time to Disease Progression (TTP) Per RECIST 1.1	TTP was assessed per Investigator, for the malignant rhabdoid tumor (MRT) & neuroblastoma patients for the pooled maximum tolerated dose (MTD) & recommended dose for expansion (RDE) according to RECIST 1.1 criteria using Kaplan-Meier method. Time to progression (TTP) is the time from date of randomization/start of treatment to the date of event defined as the first documented progression or death due to underlying cancer. If a patient had not had an event, time to progression was censored at the date of last adequate tumor assessment. At least a 20% increase in the sum of diameter of all measured target lesions, taking as reference the smallest sum of diameter of all target lesions recorded at or after baseline. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm.	Every 2 cycles (cycle = 28 days) up to end of treatment, the maximum time a patient was on study was 1311 days
Secondary	Duration of Response (DOR)	Assess the anti-tumor activity of LEE011 by RECIST 1.1. DOR was not assessed.	Every 2 cycles (cycle = 28 days) up to end of treatment, the maximum time a patient was on study was 1311 days
Secondary	Pharmacokinetics (PK) Parameter: AUC0-24	The AUC calculated to the end of a dosing interval (tau) following single dose or at steady-state (amount x time x volume-1). PK parameters were estimated from individual plasma concentration-time profiles using noncompartmental methods in Phoenix WinNonlin.	0,1, 2, 4, 8 hours post dose Cycle 1 Day 1 (C1D1) and Cycle 1 Day 15 (C1D15)
Secondary	Pharmacokinetics (PK) Parameter: Cmax	Cmax is the maximum (peak) observed plasma, blood, serum, or other body fluid drug concentration after single dose administration or at steady-state (mass x volume-1). PK parameters were estimated from individual plasma concentration-time profiles using noncompartmental methods in Phoenix WinNonlin	C1D1, C1D15
Secondary	Pharmacokinetics (PK) Parameter: Tmax	Tmax is the time to reach maximum (peak) plasma, blood, serum, or other body fluid drug concentration after single dose administration or at steady-state (time). PK parameters were estimated from individual plasma concentration-time profiles using noncompartmental methods in Phoenix WinNonlin.	C1D1, C1D15
