This Investigator-initiated, Treatment of High-Risk Prostate Cancer Guided by Novel Diagnostic Radio- and Molecular Tracers (THUNDER) study will be conducted in subjects with high-risk localized or locally advanced prostate cancer (PCa). The study contains both a randomized Phase 3 treatment intensification study, as well as a treatment de-intensification non-randomized Phase 2 study. The aim of the THUNDER study is to improve the outcome of high-risk PCa by improved risk stratification. Novel radiotracers and a genomic classifier (Decipher) will be used to guide treatment decisions, instead of standard imaging which is limited by lower sensitivity and specificity.
The hypothesis for the study is that treatment intensification based on a positive PSMA PET/ CT scan or Decipher high score (> 0.6) improves time to new metastases detected on PSMA PET/ CT in high-risk PCa. In patients who are PSMA PET/ CT negative with a low/ intermediate Decipher score (≤ 0.6), it is hypothesized that treatment de-intensification will improve patient quality of life while maintaining a good oncological outcome.
The study will be conducted at multiple centers across Europe. Participation in the study will comprise a screening period, where the screening assessments must be completed before subjects are enrolled and randomized (only for Phase 3 subjects). Eligible, consenting subjects will then undergo treatment according to their assigned study phase and treatment group, to occur over up to 96 weeks (24 months) with a post-treatment follow-up period to monitor safety and efficacy. The study will be closed when 96 events have been registered for the primary endpoint, which is expected to be at 7-8 years from the time of randomization of the first subject.

This is an open-label, single-arm, Phase 2 study of pembrolizumab plus platinum and gemcitabine (PG) in subjects with recurrent or metastatic head and neck cancer squamous cell carcinoma (R/M HNSCC). Evaluable 63 subjects with R/M HNSCC will be enrolled for examination of the efficacy and safety of the combination of pembrolizumab (200 mg IV on Day 1 of each 3-week cycle, up to 35 cycles) in combination with platinum (either cisplatin at 35 mg/m2 IV using a split-dose regimen on Day 1 and Day 8 or carboplatin at AUC 5 IV on Day 1 of each 3-week cycle, up to 6 cycles) and gemcitabine at 1250 mg/m2 IV on Day 1 and 8 of each 3-week cycle, for up to 6 cycles as first-line treatment. This study will be conducted in conformance with Good Clinical Practices. Specific procedures to be performed during the trial, as well as their prescribed timelines and associated visit windows, are outlined in the protocol.

This is an open label, non randomised, investigator-initiated Phase II study of single agent talazoparib (Talzenna®) in metastatic triple negative breast cancer patients with enriched HRD signature. Approximately 55 subjects will be enrolled in this study to examine the efficacy of talazoparib when given orally 1mg daily for days 1 to 28 for up to 28 months. The study will be conducted using the Simon two-stage phase II design, whereby this study will initially enroll 19 patients with RECIST v1.1 measurable disease with enriched HRD signature (stage I). There will be one interim analysis at the end of stage I and if 3 of the 19 have a response, then no further patient will be accrued. If 4 or more of the 19 patients have a response, then accrual would continue to stage II until a total of 55 patients have been enrolled. This study will be conducted in conformance with Good Clinical Practices. Specific procedures to be performed during the trial, as well as their prescribed times and associated visit windows, are outlined in the Trial Flow Chart.
