S1300: Pemetrexed Disodium With or Without Crizotinib in Treating Patients With Stage IV Non-Small Cell Lung Cancer That Has Progressed After Crizotinib

PRIMARY OBJECTIVES:

I. To evaluate the efficacy of the combination of crizotinib and pemetrexed (pemetrexed
disodium) compared to pemetrexed monotherapy as measured by progression-free survival (PFS)
in anaplastic lymphoma kinase (ALK)+ non-squamous non-small cell lung cancer (NSCLC) patients
who achieved clinical benefit with crizotinib monotherapy and subsequently progressed
systemically.

SECONDARY OBJECTIVES:

I. To compare the response rate (confirmed and unconfirmed, complete and partial responses)
in patients randomized to receive pemetrexed monotherapy to historical data.

II. To assess overall survival in both arms. III. To evaluate the patterns of failure
(central nervous system [CNS], extra-CNS) of the combination of crizotinib and pemetrexed and
of pemetrexed monotherapy in ALK+ non-squamous NSCLC after progression on crizotinib.

IV. To evaluate the frequency and severity of toxicities resulting from the administration of
crizotinib and pemetrexed compared to pemetrexed monotherapy.

V. To evaluate PFS and the response rate in patients treated with crizotinib following
progression on the pemetrexed monotherapy arm.

TERTIARY OBJECTIVES:

I. To compare progression-free survival (PFS) and response rates (RR) between ALK dominant
and ALK non-dominant patients in the entire study population and within each treatment arm.

II. To evaluate if the magnitude of difference in these outcomes between ALK dominant and ALK
non-dominant patients varies by treatment arm.

III. To assess blood biomarkers of sensitivity and resistance to crizotinib and pemetrexed in
an exploratory manner. The blood biomarkers include cell free circulating deoxyribonucleic
acid (DNA), micro ribonucleic acid (microRNA) before treatment, during treatment (after 2
cycles) and at treatment progression.

IV. To assess pharmacogenomic factors in peripheral blood that might affect the drug level
and treatment outcomes in an exploratory manner.

V. To assess proteomic/immunologic parameters that might affect the treatment outcomes in an
exploratory manner.

VI. To evaluate the frequency of individual mechanisms of resistance (copy number gain [CNG],
mutation, alternate oncogene).

VII. To identify alternative driver mechanisms in ALK fluorescence in situ hybridization
positive (FISH+) otherwise unknown.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive crizotinib orally (PO) twice daily (BID) on days 1-21 and pemetrexed
disodium intravenously (IV) over 10 minutes on day 1.

ARM II: Patients receive pemetrexed disodium IV over 10 minutes on day 1. Upon disease
progression or symptomatic deterioration, patients may crossover to Arm I.

In both arms, courses repeat every 21 days in the absence of disease progression or
unacceptable toxicity.

After completion of study treatment, patients are followed up for 3 years.

patients who were not able to tolerate 250 mg BID of crizotinib are not eligible for
this study

- Patients must be pemetrexed-naïve; patients may have received any number of prior
chemotherapy or molecularly targeted agents; if crizotinib was used in the 1st line
setting then chemotherapy naive patients are also eligible; if patient received
crizotinib in combination with chemotherapy, prior chemotherapy must have been
discontinued at least 14 days prior to registration and all adverse events must have
resolved to =< grade 1

- Patients must have measurable disease per RECIST documented by computed tomography
(CT) or magnetic resonance imaging (MRI); the CT from a combined positron emission
tomography (PET)/CT may be used to document only non-measurable disease unless it is
