Study information

Scientific title

A multicentre, randomised, phase III trial of platinum-based chemotherapy versus non-platinum chemotherapy, after excision repair cross-complementation group 1 (ERCC1) protein stratification, in patients with advanced/metastatic non-small cell lung cancer (NSCLC)

Acronym

ET Trial

Study hypothesis

The trial will have two main objectives:
1. To detect an improvement in survival for ERCC1 positive patients treated with a non-platinum chemotherapy compared to platinum-based treatment
2. To establish non-inferiority or improvement in survival for ERCC1 negative patients treated with a platinum-based chemotherapy compared to non-platinum treatment

Secondary objectives:
1. To examine progression-free survival, response rate and quality of life between the two treatment regimens, according to ERCC1 status
2. To investigate whether the treatment effect differs according to:
2.1. Histology (squamous versus non-squamous)
2.2. Gender (males versus females)
2.3. Performance status
3. To undertake a cost-effectiveness analysis based on all patients, and according to ERCC1 status

As of 22/02/2011 the anticipated end date for this trial has been updated from 30/11/2011 to 31/12/2014

Condition

Stage IIIb or IV non-small cell lung cancer (NSCLC)

Intervention

Patients are randomised to one of two treatment arms:
Arm A: cisplatin/pemetrexed (cisplatin 75 mg/m2 over one hour/pemetrexed 500 mg/m2 over 10 minutes - intravenous [IV] administration)
Arm B: paclitaxel/pemetrexed (paclitaxel 175 mg/m2 over three hours/pemetrexed 500 mg/m2 over 10 minutes - IV administration)

Patients will receive up to six cycles of treatment; all patients are assessed with each cycle of chemotherapy. The first post-chemotherapy visit should be completed 3 - 4 weeks after last chemotherapy cycle. Assessments will then be monthly until one year from the date of first chemotherapy cycle, then two-monthly thereafter.

Intervention type

Drug

Phase

Phase III

Drug names

Pemetrexed, cisplatin, paclitaxel

Primary outcome measures

Survival:
1. To detect an improvement in survival for ERCC1 positive patients treated with a non-platinum chemotherapy compared to platinum-based treatment
2. To establish non-inferiority or improvement in survival for ERCC1 negative patients treated with a platinum-based chemotherapy compared to non-platinum treatment

Secondary outcome measures

1. Progression-free survival and response rate using RECIST
2. Quality of life - European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ C30) with additional lung cancer questions (LC 13) and EuroQol EQ-5D
3. Cost-effectiveness analysis - assessing trial medication use, management of adverse events, if other anti-cancer treatments used, assessing hospital admission episodes (in-patient nights) and day case visits, community-based support (e.g. visits to and from GP or nurse; time in hospice)

Eligibility

Participant inclusion criteria

1. Histologically confirmed NSCLC
2. Have a tissue biopsy available for sending to the central laboratory to determine ERCC1 status
3. Presentation with stage IIIb (not amenable to curative treatment) or IV disease staging scans must be no more than 28 days prior to randomisation. Patients with relapsed NSCLC must not have received prior chemotherapy or biological therapy (previous surgery or radical radiotherapy allowed).
4. At least one measurable lesion according to Response Evaluation Criteria in Solid Tumours (RECIST)
5. Either sex, at least 18 years of age
6. Eastern Cooperative Oncology Group (ECOG) performance status 0 - 1
7. Estimated life expectancy of at least 8 weeks
8. Adequate bone marrow function as evidenced by the following (assessed within 14 days of starting treatment):
8.1. Absolute neutrophil count (ANC) equal or more than 1.5 x 10^9/L
8.2. Platelet count equal or more than 75 x10^9/L
8.3. Haemoglobin equal or more than 9 g/dL
9. Adequate liver function as evidenced by the following (assessed within 14 days of starting treatment):
9.1. Total bilirubin equal or less than 1.5 x upper limit of normal (ULN)
9.2. Aspartate transaminase (AST) equal or less than 3 x ULN or equal or less than 5 x ULN is acceptable with liver metastases
9.3. Alanine transaminase (ALT) equal or less than 3 x ULN
10. Adequate renal function as evidenced by the following (assessed within 14 days of starting treatment):
10.1. Glomerular filtration rate (GFR) greater than 50 ml/min as measured by ethylenediaminetetraacetic acid (EDTA), or
10.2. GFR greater than 60 ml/min as measured by the Cockcroft and Gault formula
11. Previous palliative radiotherapy to non-target metastatic lesions is allowed (not in the 28 days prior to randomisation)
12. Patients with stable brain metastases will be allowed to enrol. Stable brain metastases being defined as no progression of brain metastases 28 days after treatment as documented by a computed tomography (CT) scan/magnetic resonance image (MRI) of the brain. Patients with incidentally discovered asymptomatic brain metastases may be enrolled and treated with trial chemotherapy without prior brain irradiation if deemed feasible by the treating physician.
13. Signed informed consent form
14. Use of effective contraception during, and for 6 months after trial treatment by patients of reproductive potential and partners of reproductive potential. Patients who receive aprepitant (anti-emetic) must be willing to use an alternative or back-up method to hormonal contraceptives as aprepitant may reduce their efficacy.
15. Female patients with childbearing potential must have a negative serum pregnancy test prior to randomisation
