TS Stratified Chemotherapy and VEGF Inhibition in Non-Squamous Non-Small Cell Lung Cancer - Stage IV

Study Overview
=================
Brief Summary
-----------------
This study wants to determine the activity of a first-line treatment related to Thymidylate Synthetase (TS) Expression. Patients with the diagnosis of non-squamous advanced Non-Small-Cell Lung-Cancer (Stage IV) and without evidence of EGFR mutation may be enclosed in this clinical trial.

Detailed Description
-----------------
During the screening procedure tumour specimens obtained by primary biopsy, will be analysed for EGFRmut and immunohistochemically for thymidylate synthetase (TS) expression. Employing the H-Score with a cut-off of 150, EGFR-wt patients will be stratified into a TS low (Stratum A) and TS high (Stratum B) group. This procedure is aiming to provide two equally sized strata. After stratification according to the TS expression level patients will be treated with a combination of Pemetrexed, Cisplatin and Bevacizumab. Pemetrexed/Cisplatin/Bevacizumab will be administered for a maximum of 4 cycles. Patients with a complete response (CR), partial response (PR) or stable disease (SD) will continue on maintenance therapy of Pemetrexed and Bevacizumab until disease progression or unacceptable toxicity. Duration of treatment/patient: up to 1,5 years Follow Up: at least 6 month Planned number of patients: 146 treated patients

Inclusion Criteria: Histological confirmed Non-Small-Cell lung cancer Tumor stage IV (UICC 7th Version) The following histological tumor types are eligible: Adenocarcinoma (including adenocarcinomas with bronchioloalveolar differentiation) Large Cell carcinoma without neuroendocrine differentiation Mixed Cell Carcinoma without small cell fraction and without predominant squamous cell fraction undifferentiated non-small-cell-carcinoma No previous chemotherapy for stage IV NSCLC Adjuvant or neoadjuvant chemotherapy for NSCLC must be completed at least one year prior to study enrolment (from end of chemotherapy) No previous treatment with Pemetrexed or Bevacizumab Patients with prior radiation therapy may be eligible for this study if they meet the following guidelines: Previous radiation therapy is allowed to <25% of the bone marrow (Cristy and Eckerman 1987), but should have been limited and must not have included whole pelvis radiation. Patients must have recovered from the toxic effects of the treatment prior to study enrollment (except for alopecia). Prior thoracic radiotherapy must be completed 30 days before study enrollment. Lesions that have been radiated cannot be included as sites of measurable disease unless clear tumor progression has been documented in these lesions since the end of radiation therapy. Palliative extrathoracic radiotherapy to preexisting lesions may continue on study; however, these lesions may not be included as sites of measurable disease.

Measurable lesion according to RECIST 1.1 Negative pregnancy test for women of childbearing potential unless they are postmenopausal at baseline. (Postmenopausal women must have been amenorrheic at least for 12 months to be considered of non childbearing potential) Women of child bearing potential to be willing to use an acceptable method to avoid pregnancy at least one month before study start. Examples: oral contraceptives (sole application of oral contraceptives is not sufficient), diaphragm pessary, intrauterine device (spiral), condom plus diaphragm pessary plus spermicide. Exclusion Criteria: Histological confirmed predominant squamous cell carcinoma Presence of activating EGFR mutations in exons 18-21 Pregnancy or lactation period Have known central nervous system (CNS) disease, other than stable, treated brain metastasis. Stable, treated brain metastasis is defined as metastasis having no evidence of progression or hemorrhage after treatment and no ongoing requirement for dexamethasone, as ascertained by clinical examination and post-treatment brain imaging (CT scan or magnetic resonance imaging [MRI]). Patients should be off corticosteroids for 1 week (7 days) at the time of the post-treatment brain CT/MRI. Anticonvulsants (stable dose) are allowed. Treatment for brain metastases may include whole brain radiotherapy, (stereotactic) radiosurgery (Gamma Knife, linear particle accelerator, or equivalent), or a combination as deemed appropriate by the treating physician, and must have been completed > 8 days prior to Day 1 of Cycle 1. Patients with signs of a fresh bleeding into one or more cerebral metastases or with CNS metastases treated by neurosurgical resection or brain biopsy performed within 8 weeks prior to Day 1 of Cycle 1 will be excluded. Evidence of tumor invading or abutting major blood vessels Presence of a tracheobronchial fistula History of abdominal fistula or fistulisation of urogenital tract, gastrointestinal perforation or intra-abdominal abscess, inflammatory bowel disease, or diverticulitis within 6 months prior to study start Other co-existing malignancies or malignancies diagnosed within the last 5 years with the exception of a CIS of the cervix, non-melanomatous skin cancer, stable chronic lymphatic leukaemia, non-muscle invasive bladder cancer or surgically treated or irradiated prostate cancer with no signs of recurrence for one year.
