Study information
Scientific title
A prospective, randomised, open label phase II study of active specific immunotherapy with racotumomab versus support treatment in patients with advanced non-small cell lung cancer
Acronym
Study hypothesis
In patients with stages III/ IV of non-small cell lung cancer (NSCLC) racotumomab versus best support treatment prolongs survival in comparison to support treatment alone.
Please note that a phase III trial with racotumomab is already registered under http://www.controlled-trials.com/ISRCTN47153584.
On 26/06/2014 the anticipated end date was changed from 30/09/2012 to 30/06/2014.

Condition
Non-small cell lung cancer (advanced)
Intervention
Patients will be randomised to:
1. Best support treatment alone
2. Best support treatment plus racotumomab
All patients will receive best support treatment. In case a second line treatment is indicated, the drug to be used is docetaxel. Patients randomised to racotumomab group will be vaccinated until any causes of permanent discontinuation are met: unacceptable toxicity, intercurrent disease or other reactions that might in the investigator's opinion constitute an exclusion criteria and/or permanently prevent administration for more than 8 weeks, deterioration of the performance status (PS) greater than 3, patient request and/or failure to comply with treatment during 8 or more weeks.
The vaccine is administered intradermically in 4 subdoses at selected sites: deltoid region, anterior forearms, anterior thighs and posterior calf. The first 5 doses are administered at 14 day intervals and the remaining doses at 28 day intervals. If for any reason the vaccine is discontinued the patient will continue with follow up visits (every 2 months) for evaluation of survival just as the patients in the best support treatment arm do. Tumour evaluations will be performed every 8 weeks.
For racotumomab arm only blood sampling for immunological tests will be obtained at baseline for both groups and at month 2, 4, 8 and 12 and every 4 months onwards. For both treatment arms sampling for determination of suppressor cells (T reg) will be performed at baseline, month 2, 4, 8, 12 and every 4 months onwards, at disease progression and upon completion of second line therapy.

Primary outcome measures
1. Safety: will be evaluated at each study visit according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.0 and will include physical examination with vital signs, performance status (ECOG scale), laboratory tests and clinical history. Patients in racotumomab arm attend five biweekly visits (induction period of vaccination), then monthly visits until vaccine is discontinued. After vaccine discontinuation, patients on this arm continue with visits every 2 months. Patients in best supportive care arm: visits every 2 months until end of study.
2. Immunological response to racotumomab: blood sampling for this test will be performed at baseline, month 2, 4, 8 and 12 and thereafter every 4 months until death or patient withdrawal from the study
3. Determination of T reg cells for both arms: blood sampling for this test will be performed at baseline, month 2, 4, 8, 12 and thereafter every 4 months until end of second-line onco-specific therapy
Secondary outcome measures
1. Survival: survival time will be monitored from the date of random assignment to the date of death or last censored observation
2. Progression-free survival: tumour evaluations will be performed from baseline visit and every 2 months and evaluated as per RECIST

Eligibility
Participant inclusion criteria
1. The patient (aged over 21 years, either sex) can comply with the protocol and scheduled appointments and voluntarily sign the informed consent form
2. Diagnosis of NSCLC stages IIIA (surgically unresectable), IIIB or IV, according to the TNM classification version 6a, confirmed by cytology or histology, if possible available for determination of ganglioside expression
3. Patients may enter the study if they have accomplished an objective response (complete response or partial response) or disease stabilisation (by Response Evaluation Criteria In Solid Tumours [RECIST]) after completion of standard onco-specific treatment. In all cases, response should be documented.
3.1. For stage IIIA and IIIB without pleural effusion ('dry IIIB') standard treatment is considered as follows: 2 - 4 cycles of platinum-based chemotherapy and/or radiotherapy with curative intent in accordance with NCCN guidelines
3.2. For stage IIIB with pleural effusion ('wet IIIB') and stage IV standard treatment is considered as follows: 4 - 6 cycles of chemotherapy based on platinum. In case of pleural or pericardial effusion requiring local treatment, it will be provided prior to study entry.
4. Patients with an interval greater than 30 and not more than 90 days between the completion of onco-specific treatment and study entry. Completion of treatment is defined as the last day of administration of chemotherapy or the last day of radiotherapy. Patients should have recovered from any related episode of acute toxicity of degree greater than 1 (except alopecia). Patients who have received a monoclonal antibody (e.g., bevacizumab) should also have discontinued its use for at least 30 days before inclusion.
5. The subject is male or female, aged greater than or equal to 21 years
6. Performance status (Eastern Cooperative Oncology Group [ECOG]) less than or equal to 1
7. Acceptable organ functionality as defined by the following parameters:
7.1. Electrocardiogram (ECG) without significant abnormalities, performed within 14 days prior to admission
7.2. Haemoglobin greater than or equal to 90 g/L
7.3. Total leukocyte count greater than or equal to 3.0 x 10^9/L
7.4. Absolute neutrophil count greater than or equal to 1.5 x 10^9/L
7.5. Total bilirubin less than or equal to 1.5 times upper limit of normal or twice the limit normal than in case liver metastases are present
7.6. Serum glumatate serum glutamic oxaloacetic transaminase (SGOT) and serum glutamic pyruvic transaminase (SGPT) less than or equal to 2.5 times upper limit of normal (less than or equal to five times the normal maximum in case liver metastases are present)
7.7. Creatinine less than or equal to 2 mg/dL
8. Life expectancy of at least 4 months
