Condition pancreas, adenocarcinoma
Treatment biological/vaccine: bc-819
Phase phase 2
Sponsor BioCancell Ltd.
Start date September 2011
End date September 2013
Trial size 70 participants
Trial identifier NCT01413087, BC-PAN-02


This is a multicenter, open label, randomized, phase 2b study, designed to evaluate the safety and efficacy of patients with locally advanced pancreatic adenocarcinoma following intratumoral administration of BC-819 and intravenously administered gemcitabine. Intratumoral injections of BC-819 will be performed using endoscopic ultrasound (EUS).

Primary Objective: To assess the effect of intratumoral endoscopic ultrasound injection of BC-819 administered with intravenous gemcitabine on progression-free survival.

Secondary Objectives: To compare the effects of intratumoral injection of BC-819 administered in combination with intravenous gemcitabine vs. intravenous gemcitabine alone on:

Overall survival, Response rate, Resectability of the target tumor lesion, Quality of life, Safety, Serological Tumor Marker: CA 19-9, Duration of response, Failure-free survival

Study Design

Allocation randomized
Endpoint classification safety/efficacy study
Intervention model single group assignment
Masking open label
Primary purpose treatment
biological/vaccine: bc-819 DTA-H19
Post screening and prior to randomization, all patients will receive gemcitabine by IV infusion at a dose of 1000mg/m2 once weekly for four weeks. They may also enter the study if they received up to 4 doses of gemcitabine before entering the study. In this case, they will be randomized immediately provided there is no evidence of disease progression. After randomization patients will receive gemcitabine at a dose of 1000mg/m2 + 8 mg doses of BC-819 or gemcitabine at a dose of 1000mg/m2 + 12 mg doses of BC-819

Received any prior therapy for the treatment of pancreatic malignancy (including chemotherapy, immunotherapy, vaccines, monoclonal antibodies, major surgery, or irradiation, whether conventional or investigational, other than up to4 single doses of gemcitabine chemotherapy.Patients who received prior gemcitabine will only be eligible, if they enter the study without evidence of disease progression. 3.

Have a clinical history of significant coagulopathy 6. Have a medical condition contraindicated for endoscopic-guided delivery and/or for IV administration of Gemcitabine or any intercurrent medical illness or other medical condition that would in the judgment of the investigator compromise patient safety or the objectives of the study 7. Have participated in any experimental therapeutic research study with an unapproved drug within 4 weeks of the screening visit 8.

Additional Information

Official title A Multi-Center, Open-Label, Randomized, Phase 2b Study to Evaluate the Efficacy and Safety of BC-819 and Gemcitabine in Patients With Locally Advanced Pancreatic Adenocarcinoma
Description BC-819 (also known as DTA-H19) is a double-stranded DNA plasmid, 4,560 base pairs (bp) in length, carrying the gene for the Diphtheria toxin A (DT-A) chain under the regulation of the H19 promoter. This is a Targeted Cancer Therapy; DT-A chain expression is triggered by the presence of H19 transcription factors that are only up-regulated in tumor cells. The selective initiation of toxin expression results in selective tumor cell destruction via inhibition of protein synthesis selectively in the tumor cell, enabling highly targeted cancer treatment.
