BVD-523 Plus Nab-paclitaxel and Gemcitabine in Patients With Metastatic Pancreatic Cancer

Phase 1

Terminated

• Conditions: Pancreatic Cancer; Cancer of Pancreas; Cancer of the Pancreas; Pancreas Cancer
• Interventions: Drug: BVD-523; Drug: Nab-paclitaxel; Drug: Gemcitabine; Procedure: Tumor biopsy

• Registration Number: NCT02608229
• Lead Sponsor: Washington University School of Medicine

Brief Summary

In light of the central role of extracellular signal-regulated kinases (ERK) in pancreatic cancer, the investigators propose a phase I study to evaluate the ERK inhibitor BVD-523 at the recommended phase 2 dose in combination with nab-paclitaxel plus gemcitabine in patients with newly diagnosed metastatic pancreatic cancer. The primary endpoint will be maximum tolerated dose (MTD) or RP2D and safety. The secondary endpoints include safety, response rate, biochemical response, progression-free survival (PFS) and overall survival (OS). The exploratory endpoints include the assessing the impact of BVD-523 on the MEK/ERK pathway and other major pathway pertain to pancreatic cancer.

Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose (MTD) of BVD-523	Completion of cycle 1 for all dose de-escalation patients (1.8 years), the first cycle is 28 days for each individual patient	-The maximum tolerated dose (MTD) is defined as the Dose Level 1 if 0 or 1 dose-limiting toxicities (DLTs) are seen in patients at that dose level or Dose Level -1 if 2+ DLTs are seen in Dose Level 1 but only 0 or 1 DLTs are seen in patients at Dose Level -1.

Secondary Outcome Measures

Name	Time	Method
Overall Survival (OS)	Up to 2 years	-OS is defined as the days from the date of treatment start and death from any cause. Participants alive or lost to follow-up are censored.
Safety and Toxicity Profile of Treatment Regimen as Measured by Grade and Frequency of Adverse Events	30 days after completion of treatment (median time was 67.5 days)	-The descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 will be utilized for all toxicity reporting.
Response Rate	Through completion of treatment (median time was 37.5 days)	* Response rate is the percentage of participants with best response of complete response or partial response per RECIST 1.1; * Complete response (CR): disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Disappearance of all non-target lesions and normalization of tumor marker level.; * Partial response (PR): at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters.
Time to Tumor Progression (TTP)	Up to 2 years	* Time to tumor progression is defined as the days from start of treatment until progressive disease.; * Progression is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).
Progression-free Survival (PFS)	Up to 2 years	* Progression is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).; * PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Patients alive without progression or lost to follow-up are censored.
Biochemical Response of Treatment Regimen	Through completion of treatment (median time was 37.5 days)	-The biochemical response (BR) is defined as more than 50% of decrease from baseline CA 19-9
