Details and patient eligibility

About

This is a multicentric study. All patients with TET (thymic epithelial tumors) of any histological type will participate in the study. This is an open-label phase 2 study that will follow a Green-Dahlberg 2-stage design whose objective is to evaluate the activity and safety of the combination of ramucirumab (10 mg / kg) + carboplatin (AUC 5) and paclitaxel (200 mg / m2) in patients with relapsed and / or metastatic thymic carcinoma/ thymoma B3, in the first line (RELEVENT trial).

Full description

Clinical and quality of life data will be collected for all treated patient. Based on the histological evaluation performed by each participating center, patients will be screened for inclusion in one of the four studies, based on the following criteria:

• TOPS study only: all patients with A, AB, B1, B2, B3 without areas of carcinoma histology, diagnosed during or after 2018, that do not have a fresh tissue sample and screen failures of the RELEVENT and BIOTET study;
• TRY registry: all patients with TETs diagnosed, treated or followed from 2010 to 2017 included (retrospective data collection);
• BIOTET only: all patients with A, AB, B1, B2, B3 without areas of histology of the carcinoma that have a fresh tissue sample;
• RELEVENT only: all patients with thymoma B3 and areas of carcinoma and pa-tients with thymic carcinoma who do not have a fresh tissue sample.

Patients with thymic carcinoma or thymoma B3 with areas of carcinoma will receive a centralized pathological review of the tumour block or slides and will be screened to participate in the Phase II RELEVENT pharmacological study.Histological diagnosis will be confirmed before screening.

Enrollment: 60 estimated patients

Ages: 18 to 100 years old

Volunteers: No Healthy Volunteers

Patients receiving warfarin must be switched to low molecular weight heparin and have achieved stable coagulation profile prior to first dose of protocol therapy 10. adequate hepatic function as defined by a total bilirubin ≤1.5times the upper limit of normal (ULN), (Except for patients with Gilbert's syndrome who may only be included in the total bilirubin is < 3.0 x ULN or direct bilirubin < 1.5 x ULN) and aspartate transaminase (AST) and alanine transaminase (ALT) ≤ 3.0 times the upper limit of normal (or 5.0 times the ULN in the setting of liver metastases) 11. adequate renal function as defined by a serum creatinine ≤1.5 times the ULN, or creatinine clearance (measured via 24-hour urine collection) ≥40 mL/minute (that is, if serum creatinine is >1.5 times the ULN, a 24-hour urine collection to calculate creatinine clearance must be performed). The patient's urinary protein is

≤1+ on dipstick or routine urinalysis (UA; if urine dipstick or routine analysis is ≥2+, a 24-hour urine collection for protein must demonstrate <1000 mg of protein in 24 hours to allow participation in this protocol).

12. sexually active patients, must be postmenopausal, surgically sterile, or using effective contraception (hormonal or barrier methods). Female patients of childbearing potential must have a negative serum pregnancy test within 7 days prior to first dose of protocol therapy. 13. Prior radiation therapy is allowed.

• In case of chest radiotherapy a 28 days interval is needed between the end of the radiation treatment and the start of treatment .
• In the case of focal or palliative radiation treatment a 7 days interval is needed from last radiation treatment to start of treatment (and provided that 25% or less of total bone marrow had been irradiated).
• In the case of CNS radiation a minimum of 14 days interval is needed from the end of radiation treatment to start of treatment.

Exclusion criteria

1. previous systemic treatment for locally advanced/metastatic thymic carcinoma/B3 thymomas; patients treated in the neoadjuvant or adjuvant setting can be enrolled after discussion with PI
