Concurrent Pemetrexed, Cisplatin and Radiation Therapy in Patients With Stage IIIA/B Non Small Cell Lung Cancer

Recommended Phase 2 MTD was highest dose at which no more than 1 of 6 participants experienced dose level toxicity (DLT). DLT=(1) Grade 3/4 dysphagia/esophagitis, leukopenia, thrombocytopenia, febrile neutropenia, fatigue/malaise, pneumonitis, dermatitis, persistent elevation of bilirubin/alkaline phosphatase/aspartate aminotransferase only if resulting in delay of radiotherapy >1 week, delay of pemetrexed/cisplatin Cycle 2 >2 weeks, or delay of pemetrexed/cisplatin Cycle 3 past 5 weeks after radiotherapy; (2) other Grade 3 or 4 toxicity possibly related to concurrent treatment administration.

OS was defined as the time from date of enrollment to death due to any cause.

A listing of AEs is located in the Reported Adverse Event module.

OS was defined as the time from date of enrollment to death due to any cause.

Time to PD was defined as the time from study enrollment to the first date of objective disease progression as defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.0) as at least a 20% increase in the sum of the longest diameter (LD) of target lesions as references the smallest sum LD recorded since treatment started or the appearance of 1 or more new lesions. Time to PD was censored at the date of death if death was due to other cause. For participants not known to have died as of the data cut-off date and who did not have PD, time to PD was censored at the last progression-free disease assessment. For participants who received subsequent cancer therapy (after discontinuation from the study therapy) before PD, time to PD was censored at the date of subsequent cancer therapy initiation.

The percentage of participants not known to have died as of the data cut-off date or last contact and who did not have PD.

PFS was defined as the period from study entry until PD, death, or date of last contact. For participants not known to have died as of the data cut-off date and who did not have PD, the PFS date was censored at the last contact date (contacts considered in the determination of last progression free disease assessment).

Response using Response Evaluation Criteria In Solid Tumors (RECIST 1.0). Complete Response (CR)=disappearance of all target lesions; Partial Response (PR)=30% decrease in sum of longest diameter of target lesions; Progressive Disease (PD)=20% increase in sum of longest diameter of target lesions; Stable Disease (SD)=small changes that do not meet above criteria. Objective response rate (%)=number of objective responders divided by the number of participants with measurable disease * 100, where objective responders are those participants who have met criteria either for CR or PR.

Summarized participants with local (progression within the sites of initial disease)/regional (disease progression adjacent to but not within the site of initial disease at the start of treatment), distant (disease progression that is blood borne to other parts of the body, including outside the chest or involving the contralateral lung), and local + distant sites of disease. Objective PD is defined by Response Evaluation Criteria in Solid Tumors (RECIST 1.0) as at least a 20% increase in the sum of the longest diameter (LD) of target lesions as references the smallest sum LD recorded since treatment started or the appearance of 1 or more new lesions.
