Details and patient eligibility

About

The study is designed as a non-randomized Phase 2 clinical intervention study. The study will include patients with disseminated Non-Small Cell Lung Carcinoma (NSCLC) which are eligible for first line of systemic treatment with immune checkpoint inhibitors and platinum-based chemotherapy (PDL1 less than 50%). Patients will receive palliative radiotherapy to multiple sites (2 to 5 sites) prior to systemic treatment. Results of treatment will be compared to historical cohort of patients treated only with systemic therapy.

Full description

The primary objective is to investigate efficacy of radiation therapy before the first line of systemic therapy with immune checkpoint inhibitors and platinum-based chemotherapy in metastatic NSCLC (PDL1 less than 50%).

Inclusion criteria

  • Signed consent to the study before the start of the procedures related to the protocol
  • Age ≥ 18 years at time of study entry
  • ECOG performance status 0-2
  • Histologically or cytologically confirmed non-small cell lung cancer, with expression of PD-L1 of less than 50%
  • Stage IV metastatic Non-Small Cell Cancer confirmed by CT scan (of brain, chest and abdomen) or PET CT
  • Patients must be eligible for first line of systemic treatment with standard of care checkpoint inhibitor immune therapy and chemotherapy - according to the recommendations
  • inclusion of patients treated for few brain metastases (with surgery or ablative radiosurgery) is permitted (if the disease in the central nervous system is under control)
  • Prior surgery (diagnostic and therapeutic) and irradiation (for example: stereotactic irradiation of brain metastases) is permitted, provided that patients have fully recovered from the procedure at least 2 weeks before inclusion in the study
  • Patients treated with surgery or radiation and chemotherapy for limited non-small cell carcinoma in the past is permitted

Exclusion criteria

  • Metastatic non-small cell carcinoma with known oncogenic alterations suitable for targeted treatment
  • Brain or meningeal metastases that are not under control
  • Other malignancy (other than non-small cell carcinoma) present that has progressed and/or requires active treatment
  • Previous malignancy, unless cured or complete remission has been achieved for at least 2 years prior to enrolment and does not require maintenance treatment. With the exception of basal cell carcinoma or squamous cell carcinoma of skin, which was treated and precancerous diseases and in situ cancers
  • Patients with interstitial lung disease
  • The possibility of radical treatment of oligometastatic disease (primary tumour and metastases)
  • Patients who are not eligible for checkpoint immune inhibitor treatment due to contraindications such as autoimmune diseases, with the exception of some exceptions (Vitiligo; type I diabetes; hormone replacement hypothyroidism; psoriasis that does not require systemic treatment or other autoimmune diseases that do not limit checkpoint immune inhibitors treatment)
  • Previous treatment with anti PD-1, anti PD-L1, anti CTLA-4 antibodies, or any other treatment that affects T lymphocytes or checkpoint pathways
  • Patients with known sensitivity to monoclonal antibodies
  • Patients with known HIV infection
  • Patients with active or chronic hepatitis B and / or C
  • Pregnant and breastfeeding mothers
  • Patients with serious and uncontrollable health problems (physical and mental), which, according to researchers, could affect the poor participation of patients and make it difficult to interpret the results
  • Patients on corticosteroid therapy (more than 10 mg methylprednisolone or equivalent) prior to enrolment
  • Irradiation 2 months before inclusion in the study, except for stereotactic irradiation of brain metastases (or radiation and chemotherapy for limited non-small cell carcinoma in the past)
