Gemcitabine and Erlotinib Before and After Surgery in Treating Patients With Pancreatic Cancer That Can Be Removed by Surgery

4. oktober 2019 oppdatert av: Alliance for Clinical Trials in Oncology

A Phase II Study of Preoperative Gemcitabine and Erlotinib Plus Pancreatectomy and Postoperative Gemcitabine and Erlotinib for Patients With Operable Pancreatic Adenocarcinoma

PURPOSE: This phase II trial is studying how well gemcitabine and erlotinib work when given before and after surgery in treating patients with pancreatic cancer that can be removed by surgery. Drugs used in chemotherapy, such as gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving gemcitabine and erlotinib before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving these drugs after surgery may kill any tumor cells that remain after surgery.

Studieoversikt

Detaljert beskrivelse

This is a single arm, non-randomized phase II study. Eligible, fully registered patients will receive preoperative chemotherapy consisting of gemcitabine plus erlotinib. Preoperative chemotherapy will be followed by exploratory laparotomy and pancreaticoduodenectomy. Patients will then receive postoperative chemotherapy consisting of gemcitabine plus erlotinib. Up to 123 patients will be accrued to this study, with the expectation that 78 patients will remain fully eligible and evaluable for the primary endpoint. The primary and secondary objectives for the study are listed below.

Primary Objective:

To estimate the proportion of patients alive at two years from the date of registration

Secondary Objectives:

  1. To determine the resection rate (defined as the fraction of patients who proceed to planned surgery with removal of primary tumor [R0/R1]) following induction treatment with gemcitabine plus erlotinib
  2. To estimate the time to disease progression/relapse
  3. To evaluate the rate of R0, R1, and R2 resections (defined as per the 6th edition of the AJCC Cancer Staging Manual) in patients treated with preoperative gemcitabine plus erlotinib chemotherapy
  4. To evaluate the toxicity profile of preoperative gemcitabine plus erlotinib and the feasibility of postoperative gemcitabine plus erlotinib
  5. To evaluate response rates to preoperative chemotherapy for patients treated with preoperative gemcitabine and erlotinib
  6. To identify molecular predictors of pancreatic cancer response to gemcitabine combined with erlotinib
  7. To identify genetic profiles of pancreatic adenocarcinoma that may be associated with response to neoadjuvant therapy

After completion of postoperative chemotherapy treatment, patients are followed every 3 months for 2 years and then every 6 months for 2 years.

Eksperimentell: Neoadjuvant therapy + Surgery + Adjuvant therapy
As part of neoadjuvant therapy, patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, 15, 29, 36, and 43 and oral erlotinib hydrochloride once daily on days 1-43 in the absence of disease progression or unacceptable toxicity. Within 3-6 weeks after completion of neoadjuvant therapy, patients undergo pancreaticoduodenectomy and patients receive gemcitabine hydrochloride and erlotinib hydrochloride as in neoadjuvant therapy within 5-10 weeks post surgery.

Tidsramme
Overall Survival at 2 Years
Tidsramme: At 2 years post-registration

Tidsramme
Resection Rate
Tidsramme: Up to 4 years postoperative chemotherapy treatment

The resection rate is defined as the fraction of patients that proceed to planned surgery with removal of primary tumor (R0/R1) following neoadjuvant treatment with gemcitabine plus erlotinib.The resection rate will be estimated by the binomial point estimate, i.e. as the number of patients that undergo the planned surgery with removal of the primary tumor following neoadjuvant treatment with gemcitabine plus erlotinib divided by the number of evaluable patients. This quantity will also be estimated with a 95% binomial confidence interval.

Curative resection (R0) is defined as macroscopically and microscopically complete resection (with microscopic surgical margin assessment according to AJCC Staging Principles).

An R1 resection is defined as macroscopically complete tumor removal with any positive microscopic surgical margin (bile duct, pancreatic parenchyma, or SMA margins).

Up to 4 years postoperative chemotherapy treatment
Relapse/Progression-free Survival
Tidsramme: At 2 years post-registration
Relapse/progression-free survival is defined as the time from date of registration to the date of documentation of disease recurrence/progression. If a patient dies without documentation of disease recurrence/progression, the patient will be considered to have had disease recurrence/progression at the time of their death unless there is sufficient documented evidence to conclude no recurrence/progression occurred prior to death. If a patient is declared to be a major treatment violation, the patient will be censored on the date the treatment violation occurred. If a patient is lost to follow-up, s/he will be censored at the data of last contact. The distribution of disease-free survival will be estimated using the method of Kaplan and Meier.
At 2 years post-registration
Number of Participants Experiencing Grade 3 or Higher Adverse Events as Graded by the NCI's Common Toxicity Criteria for Adverse Events
Tidsramme: Up to 4 years postoperative chemotherapy treatment
The maximum grade for each type of adverse event will be recorded for each patient, and frequency tables will be reviewed to determine adverse event patterns. These patterns will be summarized with descriptive statistics. The number of patients reporting grade 3 or higher adverse events as graded by the NCI's Common Toxicity Criteria (CTCAE) Version 4 are reported here. A complete list of all reported adverse events is reported in the Adverse Events section of this report.
Up to 4 years postoperative chemotherapy treatment
Response Rate
Tidsramme: Up to 4 years postoperative chemotherapy treatment
The response rates to preoperative chemotherapy for patients treated with preoperative gemcitabine and erlotinib and rates of accurate pathologic assessment of the resected tumor specimen according to College of American Pathology guidelines will be estimated with a binomial point estimate and corresponding 95% confidence intervals.
