Dose-escalation, and Safety Study of LDE225 and Gemcitabine in Locally Advanced or Metastatic Pancreatic Cancer Patients
- Conditions
- Pancreatic Cancer
- Interventions
- Drug: LDE225+gemcitabine
- Registration Number
- NCT01487785
- Lead Sponsor
- Novartis Pharmaceuticals
- Brief Summary
This phase Ib study includes two phases: dose escalation phase and safety expansion phase.
During the dose escalation phase, successive cohorts of eligible patients (minimum 3 and maximum 6 evaluable patients per cohort) will receive increasing oral doses of LDE225 administered on a continuous once daily (QD) dose in combination of gemcitabine. This phase of the study will determine the maximum tolerated dose (MTD) and/ or recommended dose for expansion (RDE) of LDE225 administered in combination with gemcitabine in locally advanced or metastatic pancreatic adenocarcinoma patients.
During the safety expansion phase, once the MTD of LDE225 is established, additional patients will be enrolled and treated at the MTD of LDE225 in combination with gemcitabine in order to further evaluate its safety, tolerability and explore the potential efficacy of the combined treatments on the patients in locally advanced or metastatic pancreatic adenocarcinoma.

Group Intervention Description LDE225+gemcitabine LDE225+gemcitabine Increasing doses of LDE225 (from 400 mg) once a day + 1000 mg/m2 of gemcitabine on days 1, 8 and 15 of every 28 day cycle.
- Primary Outcome Measures
Name Time Method Incidence rate and category of dose limiting toxicities (DLTs) first 8 weeks of study treatment Dose limiting toxicities that occur during the first 8 weeks (56 days) of treatment with LDE225+gemcitabine. Dose limiting toxicity is defined as an adverse event or abnormal laboratory value assessed as unrelated to disease, disease progression, intercurrent illness, or concomitant medications that meets study specific criteria.
- Secondary Outcome Measures
Name Time Method Plasma pharmacokinetics(PK) parameters of LDE225 baseline, week 9 of the study Area Under the Curve (AUC), Maximum observed plasma concentration after drug administration (Cmax), Time to reach Cmax (Tmax), etc.
Incidence rate of Adverse Events and Serious Adverse Events at Informed Consent Form (ICF) sign off until 120 days after the last dose of study drug Adverse events and serious adverse events, changes in hematology and chemistry values and assessment of physical and neurological examinations, vital signs and electrocardiograms that occur during the reported period
Progression free survival baseline, 8 weeks the effect of LDE225+gemcitabine on progression free survival. Progression Free Survival is defined as the time from date of enrollment to the date of the first documented progression, or death due to any cause, or start of new anti-cancer therapy.
Antitumor efficacy of LDE225+gemcitabine baseline, week 9 of the study Efficacy endpoints (Objective response rate and progression free survival) as a function of Hh target gene expression in tumor samples
Plasma pharmacokinetics (PK) of gemcitabine Baseline, week 9 of the study If possible: AUC, Cmax, Tmax, Half life (T1/2), Total body clearance (CL), Apparent volume of distribution at steady state (Vss)
Objective Response Rate Baseline, 8 weeks The effect of LDE225+gemcitabine on objective response rate. Objective response rate is defined as the proportion of patients with a confirmed complete response (CR) or partial response (PR) as their best overall response per RECIST 1.0
Serum tumor marker Ca 19-9 On Day 1 of every cycle (cycle = 28 days) the effect of LDE225+gemcitabine on changes overtime in the serum tumor marker Ca 19-9 levels from baseline as assessed by central lab
Duration of Response Baseline, 8 weeks The effect of LDE225+gemcitabine on duration of response. Duration of response is defined as the time from the first occurrence of complete response or partial response until the date of the first documented disease progression or death due to underlying cancer.
