Repetitive electrostatic pressurised intraperitoneal aerosol chemotherapy (ePIPAC) with oxaliplatin as a palliative monotherapy for isolated unresectable colorectal peritoneal metastases: protocol of a Dutch, multicentre, open-label, single-arm, phase II study (CRC-PIPAC).

ABSTRACT: INTRODUCTION:Repetitive electrostatic pressurised intraperitoneal aerosol chemotherapy with oxaliplatin (ePIPAC-OX) is offered as a palliative treatment option for patients with isolated unresectable colorectal peritoneal metastases (PM) in several centres worldwide. However, little is known about its feasibility, safety, tolerability, efficacy, costs and pharmacokinetics in this setting. This study aims to explore these parameters in patients with isolated unresectable colorectal PM who receive repetitive ePIPAC-OX as a palliative monotherapy. METHODS AND ANALYSIS:This multicentre, open-label, single-arm, phase II study is performed in two Dutch tertiary referral hospitals for the surgical treatment of colorectal PM. Eligible patients are adults who have histologically or cytologically proven isolated unresectable PM of a colorectal or appendiceal carcinoma, a good performance status, adequate organ functions and no symptoms of gastrointestinal obstruction. Instead of standard palliative treatment, enrolled patients receive laparoscopy-controlled ePIPAC-OX (92?mg/m2 body surface area (BSA)) with intravenous leucovorin (20?mg/m2 BSA) and bolus 5-fluorouracil (400?mg/m2 BSA) every 6?weeks. Four weeks after each procedure, patients undergo clinical, radiological and biochemical evaluation. ePIPAC-OX is repeated until disease progression, after which standard palliative treatment is (re)considered. The primary outcome is the number of patients with major toxicity (grade ?3 according to the Common Terminology Criteria for Adverse Events v4.0) up to 4?weeks after the last ePIPAC-OX. Secondary outcomes are the environmental safety of ePIPAC-OX, procedure-related characteristics, minor toxicity, postoperative complications, hospital stay, readmissions, quality of life, costs, pharmacokinetics of oxaliplatin, progression-free survival, overall survival, and the radiological, histopathological, cytological, biochemical and macroscopic tumour response. ETHICS AND DISSEMINATION:This study is approved by an ethics committee, the Dutch competent authority and the institutional review boards of both study centres. Results are intended for publication in peer-reviewed medical journals and for presentation to patients, healthcare professionals and other stakeholders.

Project description:IntroductionDespite its increasing use, first-line palliative systemic therapy alternated with electrostatic pressurised intraperitoneal aerosol chemotherapy with oxaliplatin (ePIPAC-OX), hereinafter referred to as first-line bidirectional therapy, has never been prospectively investigated in patients with colorectal peritoneal metastases (CPM). As a first step to address this evidence gap, the present study aims to assess the safety, feasibility, antitumour activity, patient-reported outcomes, costs and systemic pharmacokinetics of first-line bidirectional therapy in patients with isolated unresectable CPM.Methods and analysisIn this single-arm, phase II study in two Dutch tertiary referral centres, 20 patients are enrolled. Key eligibility criteria are a good performance status, pathologically proven isolated unresectable CPM, no previous palliative systemic therapy for colorectal cancer, no (neo)adjuvant systemic therapy ≤6 months prior to enrolment and no previous pressurised intraperitoneal aerosol chemotherapy (PIPAC). Patients receive three cycles of bidirectional therapy. Each cycle consists of 6 weeks first-line palliative systemic therapy at the medical oncologists' decision (CAPOX-bevacizumab, FOLFOX-bevacizumab, FOLFIRI-bevacizumab or FOLFOXIRI-bevacizumab) followed by ePIPAC-OX (92 mg/m2) with an intraoperative bolus of intravenous leucovorin (20 mg/m2) and 5-fluorouracil (400 mg/m2). Study treatment ends after the third ePIPAC-OX. The primary outcome is the number of patients with-and procedures leading to-grade ≥3 adverse events (Common Terminology Criteria for Adverse Events V.5.0) up to 4 weeks after the last procedure. Key secondary outcomes include the number of bidirectional cycles in each patient, treatment-related characteristics, grade ≤2 adverse events, tumour response (histopathological, cytological, radiological, biochemical, macroscopic and ascites), patient-reported outcomes, systemic pharmacokinetics of oxaliplatin, costs, progression-free survival and overall survival.Ethics and disseminationThis study is approved by the Dutch competent authority, a medical ethics committee and the institutional review boards of both study centres. Results will be submitted for publication in peer-reviewed medical journals and presented to patients and healthcare professionals.Trial registration numberNL8303.

Project description:Pressurized intraperitoneal aerosol chemotherapy with oxaliplatin (PIPAC-OX) is increasingly used as a palliative treatment option for patients with colorectal peritoneal metastases (CPM). The present study aimed to systematically review all clinical studies reporting safety and efficacy outcomes of PIPAC-OX in patients with CPM. PubMed, EMBASE, The Cochrane Library, and CINAHL were systematically searched to identify all clinical studies that included at least one patient with CPM treated with PIPAC-OX and reported one of the following outcomes: adverse events, tumor response, quality of life, secondary cytoreductive surgery, progression-free survival, overall survival, and environmental safety of PIPAC-OX. Results were narratively described. Of 28 included studies, only 14 non-comparative studies separately reported at least one outcome of PIPAC-OX for CPM, of which only two studies specifically focused on this group. These 14 studies reported adverse events (5 studies), tumor response (5 studies), secondary cytoreductive surgery (4 studies), progression-free survival (1 study), overall survival (5 studies), and environmental safety (2 studies). Except for 5 studies (describing 26 patients), none of the included studies stratified their results for PIPAC-OX monotherapy and PIPAC-OX with concomitant systemic therapy, and none of the studies reporting survival outcomes stratified results for line of palliative treatment, complicating interpretation. No PIPAC-OX related deaths were reported. No occupational platinum was detected during PIPAC-OX. The available evidence regarding PIPAC-OX for CPM is limited and difficult to interpret. Despite these limitations, PIPAC-OX appears safe in patients with CPM and safe for operating personnel. To increase insight in the role of PIPAC-OX in this setting, investigators of ongoing and future studies are encouraged to report separate outcomes of PIPAC-OX for CPM, to stratify their results for PIPAC-OX monotherapy and PIPAC-OX with concomitant systemic therapy, and to stratify survival results for line of palliative treatment.

Project description:BACKGROUND:Patients with recurrent malignant epithelioid mesothelioma (MM) after surgery and standard chemotherapy with cisplatin and pemetrexed have limited treatment options. METHODS:We performed a retrospective cohort study of patients with recurrent MM undergoing Pressurized IntraPeritoneal/Thoracal Aerosol Chemotherapy (PIPAC/PITAC) with doxorubicin 1.5 mg/m2 and cisplatin 7.5 mg/m2. Data were retrospectively collected in a prospective registry of patients undergoing PIPAC/PITAC. Study outcomes were microscopic tumor regression grade (TRG), survival and adverse events (v4.0 CTCAE). RESULTS:A total of 29 patients (m/f?=?17/12) with MM with a mean age of 62.4 (range: 42 to 84) years were analyzed. A total of 74 PIPAC and 5 PITAC procedures were performed. The mean number of PIPAC applications was 2.5 (range: 0 to 10) per patient. Twenty patients (69%) had >?2 PIPAC procedure and were eligible for TRG analysis. TRG 1 to 4 was observed in 75% (15/20) of patients. Major regression (TRG 3) or complete regression (TRG 4) was observed in 20% and 10%, respectively. PIPAC induced significant tumor regression in 51.7% (15/29) of patients with a cumulative effect after repetitive PIPACs (PIPAC #1 vs. PIPAC #2: p?=?0.001; PIPAC #1 vs. PIPAC #3: p?=?0.001; PIPAC #1 vs. PIPAC #4: p?=?0.001). Postoperative CTCAE grade 4 complications were observed in two patients (6.9%) who had cytoreductive surgery (CC2) and intraoperative PIPAC. One patient (3.4%) died due to postoperative kidney insufficiency. After a follow up of 14.4 (95% CI: 8.1 to 20.7) months after the last PIPAC/PITAC application, median overall survival was 26.6 (95% CI: 9.5 to 43.7) months (from the first application). CONCLUSION:After prior abdominal surgery and systemic chemotherapy, repetitive PIPAC applications are feasible and safe for patients with end-stage MM. Furthermore, PIPAC induces significant histological regression of malignant mesothelioma in the majority of patients. PITAC is feasible, but its safety and efficacy to control malignant pleural effusion remain unclear.

Project description:BackgroundPeritoneal carcinomatosis (PC) is a common endpoint in both gastrointestinal and non-gastrointestinal cancers, and PC is treated as other systemic metastases - unfortunately with disappointing results and considerable side-effects. Pressurized IntraPeritoneal Aerosol Chemotherapy (PIPAC) is a new method of applying traditional chemotherapy, and preliminary data indicate that PIPAC is safe, able to stabilize or improve quality of life, and can induce an objectively measurable reduction in disease burden in PC.MethodsPIPAC-OPC2 is a prospectively controlled Phase II, single center, one-arm, open-label clinical trial investigating the treatment effect of PIPAC in patients with histological or cytological proven PC from gastrointestinal, ovarian or primary peritoneal cancer. Eligible patients will receive PIPAC in series of three using a combination of doxorubicin (1.5 mg/m2) and cisplatin (7.5 mg/m2) for non-colorectal cancer patients (PIPAC C/D), and oxaliplatin (92 mg/m2) in patients with PC of colorectal origin (PIPAC OX). Patients are monitored by: (1) repeated measurements of the Peritoneal Regression Grading Score (PRGS) in biopsies obtained from metal clips marked areas, (2) Quality-of-Life (QoL) questionnaires, (3) Magnetic Resonance Imaging (MRI) and (4) Prognostic Nutritional Index (PNI). Adverse events and surgical complications will be recorded according to the 30 days definition.ResultsThe primary outcome of PIPAC-OPC2 is to evaluate if PIPAC can induce major or complete response (PRGS 1 or 2) within a series of three PIPAC procedures. Secondarily this study investigates changes in QoL and MRI as a staging and response evaluation tool. The secondary outcomes will be used to create a model that may predict which of the patients will benefit from PIPAC treatment.ConclusionsIt is expected that PIPAC directed therapy can induce major or complete response in 50 % of patients with PC of colorectal origin and in 30 % of patients with PC of non-colorectal origin - and at the same time stabilize or even improve quality of life. This trial may provide data regarding the utility of MRI as a staging and response evaluation tool in patients with PC.Trial registrationThe study is registered with ClinicalTrials.gov Identifier NCT03287375 and the European Clinical Trials Database (EudraCT) number 2016-003394-18.
