Phase I-II to Evaluate Efficacy/Safety of Sorafenib+Gemcitabine+Radiotherapy in Locally Advanced Pancreatic Carcinoma

Phase 1

Completed

• Conditions: Pancreatic Cancer
• Interventions: Drug: Gemcitabine; Radiation: Radiotherapy; Drug: Sorafenib

• Registration Number: NCT00789763
• Lead Sponsor: Grupo Espanol Multidisciplinario del Cancer Digestivo

Brief Summary

Phase I: Safety profile and to determine maximum tolerated dose (MTD) / Recommended Dose (DR) of Sorafenib in combination with Gemcitabine and Radiotherapy

Phase II: Activity profile evaluating Progression-free rates (PFR) at 6 months, Response rate, Overall survival, Toxicity profile

Detailed Description

Safety profile and to determine maximum tolerated dose (MTD) / Recommended Dose (DR) of Sorafenib in combination with Gemcitabine and Radiotherapy

Definition of maximum tolerated dose (MTD):

The MTD is defined as the highest dose level which can be given to 6 patients such that no more than 1 patient experiences a DLT .

Definition of Recommended Dose (DR):

Is the MTD

Definition of Dose-limiting toxicity (DLT):

DLT will be defined as any of the following occurring during the period of treatment and regarded as related to the combination regimen.

* Grade 4 thrombocytopenia persisting greater than 4 days, or with bleeding requiring platelet transfusion

* Grade 4 neutropenia lasting more than 7 days

* Febrile neutropenia (≥ 38.5oC) with an absolute neutrophil count ≤ 1000/mm3

* Any grade 3 or 4 non-hematologic toxicity related to the combination \[occurring despite optimal supportive care, if applicable\] except hyperglycemia, hypoglycemia, deep venous thrombosis, or hyperbilirubinemia secondary to stent malfunction.

* Hypertension that is symptomatic and not managed by maximal use of three different classes of antihypertensives, or any episode of malignancy hypertension

(Detailed Dose Modifications and G-CSF use in case of febrile neutropenia will be outlined in the full protocol version)

Phase II

Primary objective:

Activity profile evaluating Progression-free rates (PFR) at 6 months

Secondary objective:

Response rate Overall survival Toxicity profile
