Clinical Benefit and Biomarker Analysis of Combination of PD-1/PD-L1 Immune Checkpoint Inhibitors and Radiotherapy

Inhibitors of the programmed cell death protein 1 (PD-1)/PD-L1 immune checkpoint signaling pathway are already approved in the treatment of various tumor entities in relapsed or metastatic stages. Different exploratory trials suggest that the combination of radiotherapy and PD-1/PD-L1 inhibitors is highly effective, especially in oligometastatic stages and if all lesions are treated with ablative radiotherapy. In addition, the role of predictive biomarkers is becoming increasingly important for future therapy algorithms. First data, also from our group, indicate clearly that dynamic changes of immune cells and their activation markers in the peripheral blood (immune matrix) can be used as predictive biomarkers. During the planned STICI-02 trial predictive immune matrix derived from the STICI01 trial (NCT03453892) will be validated in the groups of patient suffering from HNSCC (palliative), NSCLC (separately palliative and adjuvant) and "other solid tumors" (including in particular esophageal carcinomas, urothelial and renal carcinomas, small cell bronchial carcinomas and squamous cell carcinomas of the skin [depending on the current drug approval]). Within the framework of scientific accompanying projects, the predictive value of markers in tumor tissue and of pattern radiomics analyses will be analyzed accompanying the immunophenotyping in peripheral blood.

Treatment and study plan

Conventional Therapy acc. to prevailing clincal approved schemes

Other

The study is observational. The treatment-plan of the underlying disease remains unchanged. The treatment of the patient is according to the prevailing clinical approved schemes at the respective entities. Blood will be drawn from patients at several time points during and after RT and ICI for detailed immunomonitoring of the patients.

Primary outcomes

  1. Overallsurvival

    Time frame: From inclusion till death of subject or up to 5 years, whichever came first.

    Prospective investigation of the survival of the patients.

  2. Longitudinal Immunophenotype

    Time frame: Day 0 till progression or end of study up to 5 years or till change to conventional treatment without ICI, whichever came first.

    Longitudonal Immunophenotyping of the patients: Detection of about 30 distinct immune cell (sub)types together with their activation markers during treatement.

  3. Predictors in pattern recognition analyses

    Time frame: Day 0 till progression or end of study up to 5 years or till change to conventional treatment without ICI, whichever came first.

    Identification of possible predictors in pattern recognition analyses from clinical imaging data sets.

  4. Immune-associated side effects

    Time frame: Day 0 till progression or end of study up to 5 years or till change to conventional treatment without ICI, whichever came first.

    Detection of immune-associated side effects

Secondary outcomes

  1. Detection of adverse events according to NCI CTAE (v4.0)

    Time frame: From date of inclusion to the trial until the date of first documented iRECIST progression or date of death from any cause, or till change to conventional treatment , whichever came first, assessed up to 5 years.

    The adverse effects of Immunecheckpoint and Radiotherapy is recorded by official questionaire

  2. Progression free survival

    Time frame: From date of inclusion to the trial until the date of first documented iRECIST progression or date of death from any cause, whichever came first, assessed up to 5 yeras

    survival of the patient without progression of malignant disesase

  3. Treatment response (according to RECIST and iRECIST criteria)

    Time frame: From date of inclusion to the trial until the date of first documented iRECIST progression or date of death from any cause, whichever came first, assessed up to 5 years

    RECIST and iRECIST criteria will used to analyse the response of the patient to the respective treatement

  4. Attempt to establish an immune matrix of responding/non-responding patients

    Time frame: The analyses are conducted at time points before (day 0) and before every prescription of ICI (every 14 to 21 days) till progression or end of study up to 5 years or till change to conventional treatment without ICI.

    Analysis of clincal, MRI and imunnologic, molecular data to develop an biomarkermatrix with processes of machine learning
