PRophylactic Cerebral Irradiation or Active MAgnetic Resonance Imaging Surveillance in Small-cell Lung Cancer Patients (PRIMALung Study)

Korábbi kezelés

• Prior radiotherapy to the brain or whole brain radiotherapy. Note: Patients who have undergone prior stereotactic radiosurgery for benign tumours or conditions (e.g., acoustic neuroma, grade I meningioma, trigeminal neuralgia) may be considered on a case-by-case basis. Discussion with EORTC Headquarters is mandatory, before the randomization.
• Any unresolved toxicities from prior therapy (e.g., chemotherapy, radiotherapy) greater than CTCAE grade 2 (according to CTCAE v5.0) at the time of randomization.
• Unstable angina and/or congestive heart failure requiring hospitalization within 6 months prior to randomization
• Transmural myocardial infarction within 6 months prior to randomization

Más betegség

• Known contraindication to imaging tracer or any product of contrast media, such as allergy or insufficient renal function. Known contraindication to MRI, such as implanted metal devices or foreign bodies.
• Other active hematologic or solid tumour malignancy requiring current active treatment.
• Acute infection requiring treatment at the time of randomization
• Chronic obstructive pulmonary disease exacerbation or other acute respiratory illness precluding study therapy at the time of randomization
• Severe hepatic disease defined as a diagnosis of Child-Pugh class B or C hepatic disease
• Severe neurological (including dementia and epilepsy) or psychiatric disorder requiring active treatment.
• Any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before randomization in the trial

Laborértékek

• HIV positive with CD4 count \< 200 cells/microliter. Note: patients who are HIV positive are eligible, provided they are under treatment with highly active antiretroviral therapy (HAART) and have a CD4 count ≥ 200 cells/microliter within 16 weeks prior to randomization.

Egyéb

• Patient with severe active comorbidities, defined as follows:
• Any severe comorbidity that in the opinion of the Investigator might hamper the participation to the study and/or the treatment administration.

• Age ≥ 18 years
• Histologically/cytologically proven diagnosis of SCLC
• Limited and extensive stage
• LS SCLC: Stage I-III (T any, N any, M0, according to UICC TNM staging v8.0) that can be safely treated with definitive radiation doses. Excludes T3-4 due to multiple lung nodules that are too extensive or have tumour/nodal volume that is too large to be encompassed in a tolerable radiation plan.
• ES SCLC: Stage IV (T any, N any, M 1a/b), or T3-4 due to multiple lung nodules that are too extensive or have tumour/nodal volume that is too large to be encompassed in a tolerable radiation plan.
• Completed standard therapy prior to randomization:
• For patients with LS-SCLC, this includes a combination of 4-6 cycles of platinum-based doublet chemotherapy and either definitive thoracic radiotherapy (including SBRT for early-stage T1-2 N0 M0 disease who do not undergo surgery) or definitive surgical resection; thoracic radiation in addition to definitive surgical resection is allowed at the discretion of the treating physician, but is not mandated.
• For patients with ES-SCLC, this includes 4-6 cycles of platinum-based doublet chemotherapy either with or without thoracic radiotherapy
  • o Immunotherapy concurrent with and/or adjuvant to standard therapy is allowed at the discretion of the treating physician.
• Absence of progressive disease after completed standard therapy on systemic imaging (computed tomography (CT) or magnetic resonance imaging (MRI) of Chest/Abdomen/Pelvis and brain MRI), 28 days before randomization.
• Absence of brain metastases or leptomeningeal disease after completed standard therapy on systemic imaging (computed tomography (CT) or magnetic resonance imaging (MRI) of Chest/Abdomen/Pelvis and brain MRI), within 28 days before randomization.
• Interval from day 1 of last cycle of chemotherapy to randomization of ≤8 weeks
• ECOG PS ≤ 2
• Estimated creatinine clearance ≥ 30 mL/min as calculated using the MDRD formula
• Women of child bearing potential (WOCBP) must have a negative serum pregnancy test within 3 days prior to randomization.
  • Note: women of childbearing potential are defined as premenopausal females capable of becoming pregnant (i.e. females who have had any evidence of menses in the past 12 months, with the exception of those who had prior hysterectomy). However, women who have been amenorrheic for 12 or more months are still considered to be of childbearing potential if the amenorrhea is possibly due to prior chemotherapy, antioestrogens, low body weight, ovarian suppression or other reasons.
• Patients Women of childbearing / reproductive potential should use adequate birth control measures, as defined by the investigator, during the entire period of the radiotherapy treatment study participation and for at least 30 days after the last dose of radiotherapy. A highly effective method of birth control is defined as a method which results in a low failure rate (i.e. less than 1% per year) when used consistently and correctly. Such methods include:
• Combined (oestrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation (oral, intravaginal, transdermal)
• Progestogen-only hormonal contraception associated with inhibition of ovulation (oral, injectable, implantable)
• Intrauterine device (IUD)
• Intrauterine hormone-releasing system (IUS)
• Bilateral tubal occlusion
• Vasectomized partner
• Sexual abstinence (the reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient)
• Female subjects who are breast feeding should discontinue nursing prior to the first dose of radiotherapy and during the entire period of the radiotherapy treatmentuntil 30 days after the administration of the last dose of radiotherapy.
• Patient is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including follow up
• Before patient registration/randomization, written informed consent must be given according to ICH/GCP, and national/local regulations.
