Participant Group/Arm

Intervention/Treatment

EXPERIMENTAL: TH-302 + Sunitinib

TH-302 + Sunitinib. Single arm Study.

DRUG: TH-302 + Sunitinib

Combination of the two drugs in cycles of 28 days, described as follows: Sunitinib: 37,5 mg/day Oral everyday of each 28 day cycle. TH-302: 340 mg/m2 IV on days 8, 15 and 22 of each cycle.

Primary Outcome Measures	Measure Description	Time Frame
Objective Response Rate	Objective response rate: percentage of patients in whom a complete response (CR) or a partial response (PR) is confirmed according Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria in relation to the total of the analyzed population. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), >=30% decrease in the sum of the longest diameter of target lesions	approximately 36 months

Secondary Outcome Measures	Measure Description	Time Frame
Progression Free Survival (PFS)	Time between the start of study treatment to date of the first objective evidence of radiological progression or patient death due to any cause; which comes first.	approximately 36 months
Time to Tumour Progression (TTP)	It is defined as the time between the start of study treatment to date of the first objective evidence of radiological progression.	approximately 36 months
Duration of Response (DR)	It is defined as the time between the start from the first documentation of objective response (CR or PR) which is subsequently confirmed until the first objective evidence of radiological progression or death from any cause. DR is calculated only in the subgroup of patients with an objective response (CR + PR).	approximately 36 months
Overall Survival (OR)	It is defined as the time between the start of study treatment to date of death from any cause. If it were impossible to obtain confirmation of the death, survival will be censored with the date of the last Visit that it is satisfied that the patient was alive.	approximately 36 months
Safety (Adverse Events)	Safety will be assessed according to the reports of adverse events, the frequency of treatment discontinuations due to adverse events, laboratory evaluations or ECG	time between the date of signing the informed consent until 28 days after the last dose of study drug, , an average of 2 years
Biomarkers in Serum and Tumor Tissue	Assess the predictive/prognostic value of the analysed biomarkers in plasm and tumour.	approximately 36 months

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

Male or female, 18 years of age or older.
Eastern Cooperative Oncology Group (ECOG) performance status 0-1.
Histologically proven diagnosis of pancreatic neuroendocrine tumors (pNET) with Ki67 assessment of ≤ 20% (well and moderately differentiated)
Evidence of unresectable disease or metastatic disease. Locally advanced disease must not be amendable to resection or radiation therapy with curative intent.
Patients may be treated with somatostatin analogues prior or during the trial. Concomitant or prior interferon treatment is not permitted.
Documented progression disease by CT scan, magnetic resonance (MR) or Octreoscan in 12 months prior basal visit.
Measurable disease as per RECIST. Measurable lesions that have been previously radiated will not be considered target lesions unless increase in size has been observed following completion of radiation therapy.
Patient has to be able to swallow the medication.
Life expectancy greater than 12 weeks.
The definitions of minimum adequacy for organ function required prior to study entry are as follows:

Serum aspartate transaminase (AST) and serum alanine transaminase (ALT) ≤ 2.5 x upper limit of normal (ULN), or AST and ALT ≤ 5 x ULN if liver function abnormalities are due to underlying malignancy

Prior radiation therapy to > 25% of the bone marrow.
Current treatment on another clinical trial.

significant heart valve disease
cerebrovascular accident including transient ischemic attack
pulmonary embolus.
Ongoing cardiac dysrhythmias of NCI Common Toxicity Criteria for Adverse Effects (CTCAE) grade ≥ 2, atrial fibrillation of any grade, or corrected QT interval (QTc) interval >450 msec for males or >470 msec for females.
