Assess Safety & Efficacy of Selumetinib When Given in Combination With Standard First Line Treatment for Advanced Non-small Cell Lung Cancer

AstraZeneca55 enrolled

Overview

This is a Phase I, open label multicentre study of selumetinib administered orally in combination with first line chemotherapy regimens to patients with advanced/metastatic NSCLC. The study has been designed to allow an investigation of the optimal dose of selumetinib in combination with various standard first line double-platinum chemotherapy regimens. Initial assessment will be based on tolerability of selumetinib in combination with one or more selected regimens that are considered to be tolerated also being assessed for preliminary evidence of activity. This study is a dose finding and optional cohort expansion; In addition all patients will be assessed for anti-cancer efficacy of the combination of selumetinib and chemotherapy.

A Phase I, Open Label, Multicentre Study to Assess the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of Selumetinib (AZD6244; ARRY-142886) in Combination with First Line Chemotherapy Regimens in Patients with Non-Small Cell Lung Cancer (NSCLC)

Interventions

selumetinibDRUG

2 x 25mg capsules bd continuously in cohort 1 (with gemcitabine and cisplatin). If tolerated - next cohort 3 x 25mg capsules bd continuously. if higher doses are explored, required number of capsules will be provided. Option to administer on D2-19 of each 21 day cycle if required to assess tolerability of combinations with chemotherapy

gemcitabineDRUG

1250 mg/m2 iv on Day 1 and 8 of each 21 day cycle. If combination not tolerated, option to give 1000 mg/m2 iv on Day 1 and Day 8 of each 21 day cycle

cisplatinDRUG

75 mg/m2 iv on Day 1 of each 21 day cycle. If combination not tolerated, option to give 50 mg/m2 iv on Day 1 or 25mg/m2 iv on Day 1 and Day 8 of each 21 day cycle

carboplatinDRUG

If it is not possible to identify a tolerable combination of selumetinib, gemcitabine and cisplatin, cisplatin may be replaced with carboplatin (AUC5) iv on Day 1 of each 21 day cycle

pemetrexedDRUG

Gemcitabine may be replaced with pemetrexed 500 mg/m2 iv on Day 1 of each 21 day cycle.

Outcomes

Primary Outcomes

Dose Limiting Toxicity (DLT) Events in Chemotherapy in Combination With Selumetinib

Any toxicity not attributable to the disease or disease-related processess under investigation, considered related to the combination of chemotherapy plus selumetinib, which occurs within the timeframe and is dose limiting

Time frame: The first dose on Cycle 1 Day 1 up to the time before dosing on Cycle 2 Day 1, assessed up to 3 weeks

Secondary Outcomes

Best Objective Response

The best response a patient has had during their time in the study up until RECIST progression or last valuable assessment in the absence of RECIST progression. Per Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) for target lesions (TL) and assessed by MRI or CT: Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Stable Disease (SD), neither sufficient shrinkage to qualify for a Partial Response nor sufficient increase to qualify for Progressive Disease (PD); Progressive Disease (PD), \>=20% increase in the sum of the longest diameter of target lesions, the sum must also demonstrate an absolute increase of \>=5mm; Complete Response (CR), disappearance of all target lesions, any pathological lymph nodes selected as TLs must have a reduction in short axis to \<10mm

Time frame: Screening, week 6 and week 12

Percentage Change From Baseline at 6 Weeks in Target Lesion Size

The percentage change in the sum of the diameters of target lesions

Time frame: Week 6

Best Percentage Change From Baseline in Target Lesion Size

The best percentage change in tumour size a patient has had during their time in the study up until RECIST progression or last valuable assessment in the absence of RECIST progression. Percentage change was derived at each visit by the percentage change in the sum of the diameters of target lesions

Time frame: Screening, week 6 and week 12

Objective Response Rate (ORR)

The number of patients who had at least 1 confirmed visit response of Complete Response (CR) or Partial Response (PR) prior to any evidence of progression. Per Response Evaluation Criteria In Solid Tumours (RECIST version 1.1) for target lesions (TL) and assessed by MRI or CT: Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Complete Response (CR), disappearance of all target lesions, any pathological lymph nodes selected as TLs must have a reduction in short axis to \<10mm; Objective Response Rate (ORR) = CR + PR

Time frame: Up until progression or last evaluable assessment in the absence of progression, up to 9 months

AUC (0-tau)

Area under the concentration time curve (AUC) over a dosing interval at steady state (0-tau)

Cmax,ss

Maximum plasma concentration at steady state

Time frame: Cycle 2 Day1, pre-dose, 0.5, 1, 1.5, 2, 4, 8, 10 hours post dose
