Summary
Brief summary (as posted)
Thymidylate synthase (TS) is a substance the body produces naturally. The purpose of this research is to determine if there is a link between TS production and how well patients respond to treatment of non-squamous non-small cell lung cancer (NSCLC). The aim for the future is that doctors could have a better understanding in advance about which patients might respond well to pemetrexed based on how much TS they produce.

Primary outcomes (1)
- measure
- Progression Free Survival (PFS)
- timeFrame
- Baseline to measured progressive disease with follow-up every 6 weeks until progression of disease (up to 18 months after the last participant commenced induction therapy)
- description
- PFS is time from first dose to first observation of disease progression/death (any cause). PFS is reported for participants with thymidylate synthase (TS) scores. For participants not known to have died by the data cut-off date and who do not have progressive disease, PFS will be censored at date of last objective progression-free disease assessment. For participants who receive systemic anticancer therapy after study drug discontinuation and prior to disease progression/death, PFS will be censored at date of last objective progression-free disease assessment prior to chemotherapy.
