This is a proof-of-concept, Open label, randomized, multicentric, superiority phase-2 study.
Written informed consent to study procedures and to correlative studies.
Histologically or cytologically proven metastatic PDAC.
No prior treatments (chemotherapy, radiation or surgery) for PDAC
Either sex aged ≥ 18 years.
Prior malignancy within one year. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.
Prior chemotherapy or any other medical treatment for metastatic PDAC (previous adjuvant chemotherapy is allowed if terminated > 6 months previously).
Patients who have had prior treatment with an HDAC inhibitor and patients who have received compounds with HDAC inhibitor-like activity, such as valproic acid.
Current use of statins or fibrates or any medication for hypercholesterolemia for any time during the 3 months before the study.
Parallel
Valproic acid
DrugThe 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, without unacceptable toxicity. All subjects who finish treatment, whichever the reason, will enter in the follow-up. We expect that for the primary endpoint, PFS, follow-up will last up to 10 months after enrollment. Anyhow, all subjects will be followed until death and data on subsequent treatment will be collected.

Progression Free Survival (PFS)
PFS is defined as the time from randomization to the first documentation of objective disease progression by RECIST 1.1 criteria, or death due to any cause, whichever occurs first. PFS will be censored at the time of the last available tumor assessment documenting absence of progressive disease for patients alive at the time of analysis.
Objective Tumor Response Rate (ORR)
Objective Tumor Response Rate (ORR) as defined by RECIST 1.1, calculated as the proportion of patients achieving complete or partial response relative to total enrolled patients.
Duration of Objective response (DOR)
Duration of Objective response (DOR) defined as the first occurrence of a documented objective response until progression or death for any cause.
Disease Control Rate (DCR)
Disease Control Rate (DCR) defined as the proportion of patients with complete/partial response and stable disease as their best response.
Overall Survival (OS)
Overall Survival (OS) defined as the time from randomization to the date of death due to any cause. OS will be censored at the last date the patient was known to be alive for patients alive at the time of analysis.
