Valproic Acid/Simvastatin Plus Gemcitabine/Nab-paclitaxel Based Regimens in Untreated Metastatic Pancreatic Adenocarcinoma Patients

Официальное название

Randomized Phase 2 Study of Valproic Acid combinEd With Simvastatin and Gemcitabine/Nab-paclitaxel-based Regimens in Untreated Metastatic Pancreatic Adenocarcinoma Patients (The VESPA Trial).

Обзор

This is a proof-of-concept, Open label, randomized, multicentric, superiority phase-2 study.

Подробное описание

The study hypothesizes that valproic acid (VPA) in combination with simvastatin (SIM) may improve the efficacy of first-line gemcitabine and nab-paclitaxel-based regimens and extend progression free survival (PFS) as compared with chemotherapy alone, in patients with metastatic pancreatic ductal adenocarcinoma (mPDAC).

Correlative studies on tumor and blood samples could identify potential biomarkers of toxicity and efficacy helping to define personalized treatment strategy and adding new insight into the antitumor mechanism of the combination approach.

Вмешательства

• Препарат Valproic acid
  The treatment should be started within 3 days from randomization. One cycle consisted of 28 days of treatment for both arms. Patients will continue to receive study treatment up to 6 cycles until disease progression, unacceptable toxicity, physician's decision, patient's refusal, or any other discontinuation criteria. Continuation of treatment, over the six cycles, will be allowed only in case of clinical benefit, defined as continuous decrease of CA19-9 concentration or radiological response, w
