Condition non-small cell lung cancer
Treatments celecoxib, placebo
Phase phase 3
Sponsor University Hospital, Linkoeping
Collaborator Swedish Lung Cancer Study Group
Start date May 2006
End date May 2010
Trial size 319 participants
Trial identifier NCT00300729, SLCSG0501


The primary purpose of the study is to investigate if daily treatment with celecoxib, an inhibitor of cyclooxygenase-2, can prolong survival in patients with advanced non-small cell lung cancer who receive anticancer chemotherapy as their primary treatment. Secondary endpoints of the study are: health-related quality of life, toxicity, cardiovascular events, progression-free survival, and biological markers (VEGF, proteomics).

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking double blind (subject, caregiver, investigator, outcomes assessor)
Primary purpose treatment
(Active Comparator)
Four cycles of combination chemotherapy, usually with carboplatin + gemcitabine or carboplatin + vinorelbine, plus celecoxib 400 mg b.i.d. Treatment with celecoxib is continued after completion of chemotherapy. Maximum treatment duration is one year.
celecoxib Celebra
Celecoxib 400 mg twice daily, orally, starting on the same day as palliative chemotherapy. Maximum duration of treatment is one year. Treatment should be terminated earlier in case of disease progression, unacceptable toxicity, or if the patient wants to stop treatment.
(Placebo Comparator)
Chemotherapy as in arm 1 plus placebo capsules, b.i.d.
One capsule twice daily, starting on the same day as palliative chemotherapy. Maximum duration of treatment is one year. Treatment should be terminated earlier in case of disease progression, unacceptable toxicity, or if the patient wants to stop treatment.

Additional Information

Official title Cox-2-Inhibitor and Chemotherapy in Non-Small Cell Lung Cancer. A Prospective Randomized Double-Blind Study
Principal investigator Andrea Koch, MD
Description The study (CYCLUS trial, CY-cyclooxygenase-2 inhibitor, Chemotherapy, LUng cancer, Survival) is a prospective randomized double-blind multicenter trial. Patients are randomized to receive celecoxib at a dose of 400 mg b.i.d. or placebo. Primary endpoint of the trial is survival. Secondary endpoints are: quality of life, progression-free survival, toxicity, cardiovascular events, and biological parameters (plasma VEGF and proteomics). The rationale behind the study consists of preclinical observations of antitumor effect of celecoxib in NSCLC. Inhibition of angiogenesis and proliferation as well as increased apoptosis has been demonstrated. In addition, pilot studies have shown that the combination of chemotherapy and celecoxib is feasible. No unexpected toxicity has been recorded in such trials. Furthermore, a randomized study of indomethacin, prednisolone or placebo in other types of advanced cancer, mainly gastrointestinal, showed a survival advantage for patients receiving antiinflammatory treatment. Chemotherapy is given according to the current standard of the participating institution. In practice, patients will usually receive either carboplatin + gemcitabine or carboplatin + vinorelbine. Treatment duration with chemotherapy is 4 cycles (cycle length 3 weeks) in the absence of tumour progression or prohibitive toxicity. Treatment with the study drug starts on the first day of cancer chemotherapy. Maximum treatment duration is one year. Treatment will be stopped earlier in case of objective tumor progression, serious toxicity that is considered to be related to the study drug or if the patient wants to stop treatment. The size of the study is based on the hypothesis that celecoxib could prolong median survival by 8 weeks as compared to 7.5 months in the placebo group. With standard statistical requirements (type I error 5%, type II error 20%), the calculated number of patients was 760. The study was supported by the Swedish Lung Cancer Study Group and organized as a multicenter trial, with participation of seven university hospitals and six smaller hospitals. The number of new cases of NSCLC stage IIIB-IV and performance status 0-2 in Sweden is around 1200/year. It was expected that 20% of the patients could be included in the study, which would make completion possible in three years. The study was opened for randomization on May 31, 2006. Recruitment of patients was lower than expected. The study was closed for further randomization on May 31, 2009, as originally planned. 319 patients were included. Since maximum duration of treatment with the study drug is one year, the code will be broken after May 31, 2010. Data analysis is planned to take place in summer and autumn, 2010.
