This brief was prepared by Jonathan Henry Jacobsen from ASERNIP-S. 2015 Summary of findings The PleurX® Catheter system is designed to treat malignant pleural effusions (MPE) and malignant ascites. As a new and, as yet, not fully established technology, the included studies reported contrasting findings regarding the efficacy of the device. A health technology assessment of limited evidence indicated that the PleurX® catheter system resulted in higher rates of technical success and longer effusion-free periods than largevolume paracentesis. A single non-randomised comparative study reported an increase in overall survival in patients with PleurX®, compared with those undergoing chemical pleurodesis. However, this observation requires further research as it is unclear whether the increase in survival is directly attributable to the PleurX® catheter or due to differences in the baseline characteristics of the patient groups. In contrast, a meta-analysis of randomised controlled trials (RCTs) found that talc pleurodesis was more successful at managing the symptoms of MPE than the PleurX® catheter. However, all of the included studies demonstrated a consistently strong safety profile, with few adverse events being reported with the PleurX® catheter. The economic analysis performed by the UK’s National Institute for Health and Care Excellence demonstrates a cost benefit of the PleurX® catheter compared to inpatient large-volume paracentesis. However, this benefit is lost when the compared to outpatient large-volume paracentesis. Two RCTs are due to be completed within 48 months. 2015 HealthPACT Advice HealthPACT noted that this technology is this technology is appropriate to use for malignant pleural effusions and malignant ascites. In addition, the technology is relatively inexpensive, convenient and safe to use and is likely to gradually diffuse into Australian clinical practice. HealthPACT notes that no further assessment of the evidence is required at this time and supports the introduction of this technology into the public sector. PleurX® catheter system for malignant pleural effusions: Update July 2015 1 TECHNOLOGY BRIEF UPDATE 2015 Technology, Company and Licensing Register ID WP038 Technology name PleurX® catheter system Patient indication Patients with recurrent, malignant pleural effusions with or without trapped lung syndrome Reason for assessment In 2012, a Technology Brief was completed to investigate the use of the PleurX® tunnelled pleural catheter system in patients with symptomatic, recurrent malignant pleural effusions (MPE) and trapped lung syndrome. In light of the continually developing evidence on the subject, the Brief recommended that this technology be monitored for further evidence in 48 months. In line with this recommendation, the purpose of the current Update is to consider the evidence that has emerged since 2012, and to determine whether this new evidence may provide additional information to inform policy decisions. Description of the technology The PleurX® (CareFusion Corporation, California, USA) tunnelled pleural catheter system was developed to control symptomatic, recurrent MPE and trapped lung syndrome. The PleurX® device and similar catheters are referred to as in-dwelling pleural catheters, and act to facilitate the drainage and re-expansion of the lung. The catheter is positioned using ultrasound or X-ray guidance while the patient is under conscious sedation. The procedure is minimally invasive and may be performed in a hospital or outpatient setting using local anaesthetic. The standard treatment for MPE is pleurodesis (removal of the pleural space) using chemical agents such as talc poudrage. The limited peer-reviewed literature indicated that the PleurX® catheter is relatively safe and improves symptoms for patients with MPE. Placement of an in-dwelling pleural catheter may offer patients with poor quality of life and limited life expectancy shorter hospital stays and fewer major complications.

However, the extent to which the PleurX® catheter system has diffused is unclear. 2015 International utilisation Country Level of Use Trials underway or completed Limited use Widely diffused Canada Egypt Germany Italy Netherlands Spain UK USA 2015 Cost infrastructure and economic consequences CareFusion Corporation has indicated that the insertion kit (vacuum bottle and catheter) and the 500 mL and 1000 mL drainage bottles cost $425, $56.65 and $64.38 respectively.2 Additional costs associated with the PleurX® Catheter system include the training of, and PleurX® catheter system for malignant pleural effusions: Update July 2015 2 visits from, community nurses. CareFusion Corporation contends that the cost of the catheter system and nurse visits are offset by the reduction in hospital visits; however, this contention could not be confirmed. 2015 Evidence and Policy Safety and effectiveness One systematic review (level I interventional evidence), one health technology assessment (HTA) (level III-2 interventional evidence) and one non-randomised comparative study (level III-3 Interventional evidence) were included in the Technology Brief Update (Table 1). The included studies evaluated the safety and efficacy of the PleurX® catheter system for MPE. The comparator to the PleurX® catheter system was large-volume paracentesis in the HTA and chemical pleurodesis in the systematic review and non-randomised comparative study. All three studies evaluated adverse events attributable to the PleurX®.

The PleurX® catheter system for malignant pleural effusions: Update July 2015 3 authors searched four literature databases (The Cochrane Library, EMBASE, Medline and PubMed) for relevant studies published up to May 2014. The search terms were not reported. Data was meta-analysed where possible. Three RCTs involving a total of 370 patients with MPE were included in the systematic review (Table 2). The length of follow-up ranged from 1 to 12 months. PleurX® was compared with talc chemical pleurodesis in two studies and with doxycycline in one study.

However, there was significant heterogeneity within and between the included studies (I2 statistic=87%). A subsequent sensitivity analysis of studies that compared tunnelled pleural catheters to talc pleurodesis, determined that tunnelled pleural catheters were less likely to achieve success than talc pleurodesis (p<0.001). Two RCTs reported that the PleurX® system reduced hospital stay (range 0 to 1 day) compared with chemical pleurodesis (range 4 to 6.5 days) (p-value not reported). Safety No deaths were reported. There was no difference in the number of adverse events between tunnelled pleural catheter and chemical pleurodesis (p<0.05). White & Carolan-Rees 20124 The aim of the HTA conducted by the National Institute of Health and Care Excellence (NICE) was to compare the safety and effectiveness of the PleurX® catheter system with largevolume paracentesis for patients with treatment-resistant, malignant ascites and to determine whether the technology should be adopted by the National Health Service in the United Kingdom. Published literature, information provided by the sponsor (CareFusion Corporation) and input from a Medical Technology Advisory Committee informed the evidence base for the PleurX® catheter system for malignant pleural effusions: Update July 2015 4 HTA. The HTA included 10 studies submitted by the sponsor: one non-randomised comparative study, eight case series (one of which was a conference abstract) and one case report (Table 3). The HTA reported on six clinical outcomes: the technical success of the catheter insertion and drainage procedure; resolution of symptoms; quality of life outcomes; adverse events; drainage frequency; and resource consumption. These outcomes were infrequently reported by the included studies. The most commonly reported findings are presented below.

Overall, all five studies reported a high success rate (100 per cent). Only one study reported a minor intraoperative adverse event; however, detail regarding the event was not reported. Catheter patency at the end of the study or at death was 67 per cent in the non-randomised comparative study and ranged between 85 and 100 per cent in the case series. The Medical Technology Advisory Committee noted any potential improvements in quality of life were due to the reduction in hospital visits and alleviation of symptoms due to smaller, more frequent drainage. However, the Committee was uncertain of when the PleurX® catheter system for malignant pleural effusions: Update July 2015 5 PleurX® catheter should be offered in the clinical pathway of a patient. It was suggested that this be left to the discretion of the physician and patient. Safety A single case series study reported a mortality rate of 90 per cent at the end of the study.14 The deaths were attributable to the natural disease progression and not the PleurX® catheter system. No other study reported the number of deaths. The non-randomised comparative study reported complication rates of 7.5 per cent for both patients in the PleurX® catheter system and those in the large-volume paracentesis groups. The rate of adverse events ranged from 0 to 59 per cent in the case series studies. Loculations (pockets of fluid) and fluid leakage were the most commonly reported adverse events. The HTA concluded that the PleurX® catheter system was safe and effective when compared with large-volume paracentesis. Srour et al. 20135 The outcomes of 360 Canadian adults with MPE who were treated with either the PleurX® catheter system (n=193) or chemical pleurodesis (n=167) between March 2003 and April 2009 were retrospectively analysed. One study author conducted all of the pleural catheter placements either as an inpatient or outpatient procedure between May 2006 and April 2009. A community nurse visited the patient at home three times a week to drain the catheter. The catheters were removed when the volume of pleural effusion was less than 50 mL on three consecutive visits. Chemical pleurodesis, which involved placing five grams of talc within the pleural cavity, was performed between March 2003 and February 2006. There were no statistically significant differences between the tunnelled pleural catheter and the chemical pleurodesis group with respect to baseline characteristics such as age, previous chest irradiation and side of intervention. However, there were significantly more patients in the tunnelled pleural catheter cohort with lymphoma (p=0.005) and mesothelioma (p=0.008). By contrast, gynaecological tumours were more common in the chemical pleurodesis group. Effectiveness Throughout the analysis period, 167 of the 193 patients (87%) in the tunnelled pleural catheter group and 156 of the 167 patients (93%) in the chemical pleurodesis groups had died ( PleurX® catheter system for malignant pleural effusions: Update July 2015 6 Table 4).

Further, the effusion-free and overall survival time was longer for patients with a PleurX® catheter than for those who received chemical pleurodesis. The authors attributed the greater survival time to better effusion control observed in the in-dwelling pleural catheter cohort. Patients who received tunnelled pleural catheters required significantly fewer reinterventions (thoracostomy) compared with those who received chemical pleurodesis group (p<0.01). The PleurX® catheter was removed in 96 patients before they died. Of these, 26 patients (27%) experienced recurrent pleural effusion. Safety Transient respiratory deterioration occurred less frequently in the tunnelled pleural catheter group (0% versus 4%; p<0.004). There were no statistical differences with respect to other adverse events such as catheter blockage, fever, fluid leak, development of pneumothorax, pain, bleeding, catheter dislodgement or cellulitis. 2015 Economic evaluation White & Carolan-Rees 20124 The sponsor (CareFusion Corporation) submitted a decision tree with an embedded Markov model to determine the cost-effectiveness of the PleurX® catheter system. The model examined patients with malignant, treatment-resistant ascites who received either the PleurX® catheter system or large-volume paracentesis as an inpatient or outpatient PleurX® catheter system for malignant pleural effusions: Update July 2015 8 procedure. The model duration was 26 weeks owing to the high associated mortality rate of the condition. The model assumptions were: no change in survival rates; a similar level of treatment monitoring for all treatment options; the need for two nurse visits to train the patient to self-manage drainage; an at home nurse visit (15 minutes); a drainage volume of 9.2 litres per procedure for large-volume ascites; an average drainage volume of 3.5 litres per week for the PleurX® catheter; and the cost of reintervention similar to a first-time catheter insertion procedure. The cost per patient treated with PleurX® was GBP £2,466 ($3,319), compared with GBP £3,146 ($4,235) and GBP £1,457 ($1,961) for inpatient and outpatient paracentesis. Basecase analysis demonstrated a saving of GBP £679 ($914) per patient when the PleurX® catheter system was used compared with inpatient large-volume paracentesis. However, the PleurX® catheter cost an additional GBP £1,010 ($1,359) per patient, compared with outpatient large-volume paracentesis. The cost saving for PleurX® was heavily dependent on the reduced number of bed days, which were valued at GBP £312 ($420) per day. An economic evaluation19 of the TIME2 trial6, a RCT comparing an in-dwelling pleural catheter (Rocket Medical Pty) to talc pleurodesis for MPE, concluded the total mean cost for the catheter and talc pleurodesis was USD $4,993 ($5,176) and USD $4,581 ($4,749) respectively. The total mean difference was USD 401 ($416) (95% CI, $-1,438 to $2,344) however, this was not statistically significant. A sensitivity analysis demonstrated a cost saving of USD $1,719 ($1,782) per patient when an in-dwelling pleural catheter was used in patients who survive for 14 weeks or fewer. The cost saving was lost for patients who survive for more than 14 weeks. 2015 Ongoing research Searches of ClinicalTrials.gov and the Australian and New Zealand Clinical Trials Register identified one clinical trial investigating the impact of doxycycline on the PleurX® catheter system for pleural effusion in Canada. An additional trial was found investigating a tunnelled pleural catheter for pleural effusion in Singapore. However, the manufacturer of the catheter was not reported ( PleurX® catheter system for malignant pleural effusions: Update July 2015 9 Table 5) PleurX® catheter system for malignant pleural effusions: Update July 2015 10 Table 5 Registered clinical trial characteristics Trial Identifier/ Location Design Number of patients Intervention Outcomes Trial status (Estimated completion date) NCT01411202 Canada RCT Blinded, parallel assignment 40 PleurX® with injection of 500 mg doxycycline in 50 mL of normal saline Primary: Time to pleurodesis up to 90 days Secondary: Rate of pleurodesis, number of adverse events and pulmonary function at 90 days Recruiting December 2016 Primary: Number of hospital days for all causes up to 1 year Secondary: Number of hospital days attributable to pleural effusion, number of adverse events, breathlessness score, selfreported quality of life score, health costs up to 1 year Recruiting May 2015 PleurX® with placebo injection of 50 mL of normal saline NCT02045121 Singapore RCT Open label, parallel assignment 160 Tunnelled pleural catheter Talc pleurodesis RCT, randomised controlled trial 2015 Other Issues There are many manufacturers of tunnelled pleural catheters.

The Pleurx® device and similar catheters are referred to as indwelling pleural catheters. The catheter is placed using ultrasound or X-ray guidance by appropriately trained personnel under conscious sedation with local anaesthetic. The procedure is minimally invasive and may be performed in a hospital or outpatient setting. The traditional standard of care for MPE is pleurodesis using chemical agents such as talc Title: Month Year 1 poudrage or slurry. The limited peer-reviewed literature indicated that the Pleurx® catheter is relatively safe and improves symptoms for patients with MPE. Placement of an in-dwelling pleural catheter may offer patients with limited quality of life and duration of survival shorter hospital stays and fewer major complications. In-dwelling pleural catheters are a well-established technology; however, their role in the broader context of a multidisciplinary team dedicated to pleural services is an area undergoing development. Background Pleural effusion refers to the build-up of abnormal amounts of fluid in the pleural space due to excess production or decreased absorption of fluid. Effusions result in a flattening of the diaphragm, dissociation of the pleura, and reduced ventilation. Malignant cells in the pleural fluid and/or parietal pleura indicate the presence of MPE and advanced disease. MPE is most commonly symptomatic and patients experience dyspnoea (shortness of breath), coughing, and pain on breathing. An MPE is considered recurrent when a patient who has undergone a pleural drainage procedure presents with another pleural effusion on the same side.1 Median patient survival following diagnosis of MPE ranges from three to 12 months. Life expectancy depends on the stage and type of the underlying malignancy. Primary tumours of the lung and breast account for a 50-65 per cent of all MPE diagnoses and the rest are associated with lymphomas or tumours of the genitourinary or gastrointestinal tracts, or other locations.2 Discovery of an MPE indicates disseminated and/or advanced disease and MPE management options are focused on drainage of fluid and relief of symptoms. Patients presenting with MPE are a heterogeneous patient population with variable life expectancy and quality of life; the management of MPE must therefore be highly individualised. The complex nature of managing MPE precludes the adoption of a single treatment pathway for the condition.3 Factors which may influence treatment strategy for MPE include the severity of symptoms and life expectancy of the patient, histology of the primary tumour, and the tumour’s response to therapy. The degree of lung re-expansion following fluid removal is also a determinant of therapeutic strategy. The provision of pleural services requires a multi-disciplinary team approach to the management of MPE. This includes the need for a team of staff trained in both the diagnosis and management of pleural disease, access to clinic facilities with dedicated areas for pleural procedures, and appropriate resources and technology to offer a range of timely interventions.4 For the treatment of MPE the aim of pleural services is to provide rapid symptomatic relief with a minimal number of invasive procedures, a focus on ambulatory care, and limited hospital stays. Pleural services also facilitate ongoing access to care in the community setting and appropriate patient follow-up. In the absence of appropriate followup, patients may present to emergency departments with complications or recurrence of PleurX® catheter system for malignant pleural effusions: Update July 2015 2 symptoms and subsequently undergo invasive or unnecessary procedures.4 The role of pleural services in the management of patients with pleural disease and MPE in the Australian context is an area currently undergoing development. Treatment options for MPE include: observation (if the patient is asymptomatic); therapeutic pleural aspiration (in patients with life expectancy shorter than one month); thoracoscopy with intercostal tube drainage and instillation of a sclerosant (pleurodesis)- provided the underlying lung expands fully. This is performed by a specialised proceduralist in a theatre setting; Tube thoracostomy with pleurodesis using talc slurry. This procedure may be performed as a bedside procedure in an inpatient setting; and placement of an in-dwelling pleural catheter under ultrasound or X-ray guidance. For recurrent MPE, the treatment standard is pleurodesis using chemical agents provided the underlying lung expands fully.5 Thoracoscopy is a percutaneous procedure in which an endoscopic instrument is placed within the pleural space to visualise and sample the pleura. The procedure can be used as a diagnostic tool or for therapeutic drainage or pleurodesis. Thoracoscopy alone can facilitate lung re-expansion and positioning of the pleura for pleurodesis. The procedure has a low peri-operative mortality rate. Major complications (uncommon) include empyema and acute respiratory failure secondary to infection or re-expansion pulmonary oedema.2 Therapeutic thoracoscopy involves installation of a drainage tube to relieve the effusion, known as thoracostomy. Pleurodesis may be performed in conjunction with therapeutic thorascopy in a theatre setting using talc poudrage/insufflation; or, at bedside using talc slurry via tube thoracostomy. Instillation of the sclerosant causes irritation of the pleura and subsequent closure of the pleural space. This prevents the build-up of fluid and is considered the definitive treatment for MPE. A survey of 859 pulmonologists in the United States, United Kingdom, Canada, Australia, and New Zealand found significant variation in how pleurodesis is performed. The study also determined that pleurodesis agents currently available are perceived as suboptimal with talc poudrage or insufflation and talc slurry perceived to be the most effective. 6 In-dwelling pleural catheters (IPCs) are soft, flexible catheters placed in the pleural space and tunnelled through the subcutaneous tissue. IPCs are inserted under local anaesthetic and light sedation, most often in the outpatient setting. Attachment of a vacuum drainage bottle facilitates drainage and re-expansion of the lung and the catheter may remain in situ PleurX® catheter system for malignant pleural effusions: Update July 2015 3 until death. Fluid may be drained as required, by patients, and in the home setting. The catheter may be removed if the patient experiences spontaneous pleurodesis.7 A disadvantage associated with the device is the duration of treatment; the catheter may remain in the patient’s body for extended periods of time, causing unease or exposing the patient to the risk of infection. For patients receiving an IPC, accessibility to appropriately trained staff from a number of specialties for follow-up and removal of the catheter (if necessary) should form a part of their management strategy.4, 8 For patients presenting with trapped lung syndrome (where the lung cannot achieve full expansion) associated with MPE, tube thoracostomy and pleurodesis are not indicated and more invasive therapies are problematic as they require long recovery periods. As a result, the Pleurx® catheter may be an attractive therapeutic approach for these patients.2, 9 2012 Clinical need and burden of disease MPE is common, affecting 660 patients per million each year.10 In Australia and New Zealand this equates to over 13,000 patients per annum.10 The incidence of MPE can be expected to rise with increased population and life expectancy and the increase in mesothelioma cases over the coming decades. Australia has a high incidence of mesothelioma, a cancer associated with exposure to asbestos. The age standardised incidence of mesothelioma was 2.8 per 100,000 people in 2005 and as many as 700 cases are diagnosed each year.11 In 2010-2011, Medicare processed 1,162 claims for Medicare Benefits Schedule item number 38436 for thoracoscopy, with or without division of pleural adhesions, including insertion of intercostal catheter where necessary, with or without biopsy.12, 13 It should be noted that this item number is not exclusive to the treatment of MPE. 2012 Diffusion of technology in Australia There are several pleural drainage systems available including the Pleurx® catheter15 which was approved in 2007 and is marketed within Australia.

Pleurodesis is the conventional management strategy for MPE. Common sclerosants used for pleurodesis include talc poudrage or slurry, and bleomycin. Sclerosants are introduced via an intercostal tube and may require significant surgical resources and lengthy hospital stays. Pleurodesis is not suitable for patients with trapped lung syndrome. 2, 14 Table 7 Additional approved pleural drainage systems Manufacturer Name of device ARTG number Admac industries Pty Ltd Drainage system, pleural 135724 Atrium Australia – Pacific Rim Pty Limited Drainage system, pleural 119726 ® B Braun Australia Celsite Access Ports 137318 Baldwin Medical & Veterinary Devices (Australia) Pty Ltd Drainage system fluid collector, pleural 162220 Control Medics Pty Ltd Pleura-safe 162038, 157981, 120316 Coviden Pty Ltd Drainage system, pleural 187240, 187241, 144075, 145734 Rocket Medical Pty Ltd Pleural & Peritoneal Catheter System 145658, 14379, 166369 William A Cook Australia Pty Ltd Drainage system, pleural 142280 ARTG: the Australian Register of Therapeutic Goods 2012 Safety and effectiveness One systematic review and one randomised controlled trial (RCT) were selected for inclusion in this technical brief.

Source: Clinical Trials Database (US) accessed May 2012. 16, 17 PleurX® catheter system for malignant pleural effusions: Update July 2015 7 Van Meter et al (2010)5 This systematic review included one RCT (level II evidence) and 18 case series (level IV) assessing the safety and effectiveness of the Pleurx® catheter in 1,370 patients. The RCT compared placement of the Pleurx® catheter to pleurodesis.17 The methods, including search strategy (to October 2009), databases searched, study selection criteria and data analysis, were clearly detailed. Of the 1,370 included patients, nine were treated with a Tenckhoff catheter (a small-bore flexible tube tunnelled into the pleural space). All other patients were treated with the Pleurx® catheter. Per protocol analysis was conducted where studies did not report outcomes the patients were removed from both the numerator and denominator. All included studies aside from the single RCT were uncontrolled, retrospective, case series with variable reporting of key outcomes. When reported, outcomes were generally not graded for severity. The patients treated with IPCs in the included literature were adult patients with an effusion in the setting of malignancy. This limits the transferability of findings to more defined patient populations and introduces several confounding factors such as the size of effusion, patient comorbidities and patient life expectancy. Effectiveness Mean time to pleurodesis was 52 days (reported by 12 studies). Catheter removal was attributed to spontaneous pleurodesis in 381 of 808 patients (47%). Amongst the 12 studies reporting spontaneous pleurodesis, the incidence ranged from 12 per cent to 76 per cent and symptomatic improvement from 86 per cent to 100 per cent. Symptomatic improvement was variably defined across the included studies and consisted of the following descriptive terms: “symptomatic improvement”; “relief of dyspnoea”; “improvement in respiratory performance status”; “increased exercise tolerance”; “improvement of pain”; and, “catheter was useful”. One study rated improvement of dyspnoea using a three-point scale. Table 10 summarises the effectiveness outcomes presented in the systematic review.

Inclusion criteria were malignancy with at least a moderate sized pleural effusion and dyspnoea relieved after therapeutic thoracentesis. As the comparison between the Pleurx® catheter and pleurodesis was not included in the systematic review, the results of this trial are included here. Forty five patients were randomised to treatment with pleurodesis and 99 to Pleurx®. Four patients from the pleurodesis group and two patients from the Pleurx® group did not receive the intended treatment, or were withdrawn from the study due to protocol violations (incorrect sclerosant or incorrect treatment timing). Patient disability was assessed using the validated PleurX® catheter system for malignant pleural effusions: Update July 2015 9 assessment tools, the scale for dyspnoea (Borg score) and a quality of life questionnaire (Guyatt CRQ). Safety Early in-hospital morbidity (e.g., fever, pneumothorax) occurred in six of 43 (14%) patients treated by pleurodesis and 10 of 94 (11%) patients treated by Pleurx®. One patient in the Pleurx® group experienced hypercapnic respiratory failure secondary to over-sedation and no procedure-related deaths occurred. The degree of pain experienced by patients in the two groups was similar and there was no significant difference between groups in the amount of analgesic received. Table 12 summarises the safety outcomes, including the fact that patients in the Pleurx® group experienced more late complications. Table 12 Early and late morbidity Pleurx® (n=94) Pleurodesis (n=43) Early morbidity (in hospital) Fever 3 Fever 2 Pneumothorax 3 Severe pain 2 Misplacement of the catheter 2 Hydropneumothorax 1 Re-expansion pulmonary oedema 1 Chest tube replacement 1 Late morbidity (in the 90-day follow-up period) Local cellulitis around the catheter tract 6 Pleural infection 1 Catheter obstruction 2 Pain during fluid drainage 7 Tumour seeding of catheter tract 3 Pain at chest tube site 1 Effectiveness Effectiveness outcomes are summarised in Table 13. The median hospitalisation time (the time from randomisation to discharge), for patients in the Pleurx® arm was significantly shorter than for patients in the pleurodesis arm (1 day versus 6.5 days; p<0.0001). Treatment failure was defined as recurrence of effusion after initial control and occurred in 12 patients (13%) in the Pleurx® group and six (21%) in the pleurodesis group (p values not reported). All six patients in the pleurodesis group experienced failure within 30 days. In the Pleurx® group, recurrence was due to loculations in seven patients (58.3%). In two patients, recurrence occurred after initial spontaneous pleurodesis and in a further two, after catheter occlusion. Replacement of the catheter after occlusion resulted in spontaneous pleurodesis in one patient. One patient did not have a determined cause of recurrence.

The patient starter kit contains four drainage bottles and maintenance materials. Two studies incorporating cost data specific to Pleurx® were identified in the literature. A retrospective review identified 100 patients treated with Pleurx® and compared those patients to 68 treated with pleurodesis.19 As a component of the analysis, hospital charges for each patient were obtained from the time of admission to seven days post-procedure and treatment strategies were compared. The analysis determined that outpatient treatment with Pleurx® was less costly than inpatient treatment with Pleurx®. The study also indicated that outpatient Pleurx® treatment was associated with significantly lower mean hospital charges as compared to inpatient pleurodesis. Table 15 below summarises the results. Table 15 Costs associated with treatments for MPE Mean hospital charges (US dollars) Pleurx® inpatient, N=40 Pleurx® outpatient, N=60 Pleurodesis, N=68 11,188 ± 7,964 3,391 ± 1,753 7,830 ± 4,497* Data is reported as a mean and standard deviation. p<0.001 as compared to inpatient Pleurx®. MPE: malignant pleural effusions A second study using Medicare data from the US assessed the incremental cost effectiveness of treating MPE with talc pleurodesis versus placement of the Pleurx® catheter (outpatient procedure).20 The study did not explicitly discriminate between bedside pleurodesis and thoracoscopic pleurodesis. The study determined that treatment with the catheter was marginally more costly and less effective than treatment with talc. Cost data were estimated using Medicare Diagnosis-Related Group (DRG) reimbursement data from 2008 and integrated into a base-case scenario. The analysis was conducted from the perspective of an insurer and considered only direct health care costs to patients and direct insurance-covered costs. The time horizon for the model was six months and effectiveness was evaluated using the outcome of “effusion resolved” with patients assumed to be alive after six months. The base-case estimate of probability of success (resolved effusion) was 0.80 with talc pleurodesis and 0.45 for catheter placement. The study found that treatment with talc was slightly less costly than placement of the Pleurx® device (talc, US$8,170.80; Pleurx®, US$9,011.60) although Pleurx® became more cost effective when life expectancy was six weeks or less. Table 16 summarises the cost estimates for procedure-related admissions and equipment presented in the study. Table 16 Costs associated with talc pleurodesis and Pleurx® device placement Item Cost in US dollars (2008 ) Admission for talc 5,279 PleurX® catheter system for malignant pleural effusions: Update July 2015 12 Admission for infection 7,877 Visit with physician 100 Placement of Pleurx® 1,956 Case of Pleurx® supplies (10 boxes) 750 The differences in reported costs between the two studies may be attributable to the type of analysis performed. One study considered mean hospital charges from a third party insurer’s perspective with efficacy considered independently. The other modelled the incremental cost effectiveness of the treatments relative to each other using decision analysis. An important cost consideration for the placement of an in-dwelling pleural catheter is whether a patient has ongoing access to trained staff in a day procedure setting. Insufficient follow-up may result in patients presenting to emergency departments and undergoing further interventions for complications or recurrence of symptoms, thereby increasing the costs associated with catheter placement.8 Appropriate clinical end-points for a cost analysis of the technology may include: the rate of spontaneous pleurodesis; rate of re-intervention; duration of hospital stay; and the rate of adverse events. However, an analysis of these endpoints will also be affected by the confounding factors of patient co-morbidity, underlying malignancy and life-expectancy. Areas of future research include the costs associated with the provision of pleural services, in which, IPCs are considered as part of a patient’s individual management plan. Ethical, cultural or religious considerations No ethical, cultural or religious considerations were identified. 2012 Other issues There is limited comparative data in trials using the Pleurx® device; and, where available, the comparator pleurodesis arm involves an out-dated form of pleurodesis (doxycycline). There are two recently published studies which use another in-dwelling pleural catheter (Rocket Medical, Washington, US) in a comparison with pleurodesis.14, 22 A trial conducted in Western Australia compared treatment with an in-dwelling pleural catheter (IPC; Rocket Medical, Washington, UK) to pleurodesis in a prospective, multicentre study; in which, treatment strategy was based on patient choice. The investigators concluded that patients treated with the catheter required significantly fewer days in hospital compared to those who received pleurodesis. The study reported fewer additional pleural procedures amongst patients treated with an IPC and noted that safety profiles and symptom control were comparable. 14 PleurX® catheter system for malignant pleural effusions: Update July 2015 13 A randomised controlled trial in the UK (conducted in 7 centres) compared treatment with an IPC (Rocket Medical, Washington, UK) to pleurodesis by chest tube insertion and talc slurry. The investigators found no statistically significant difference between IPCs and pleurodesis at relieving patient-reported dyspnoea. The length of initial hospitalisation was significantly shorter in the IPC group as compared to the pleurodesis group (p<0.001); however, differences in the quality of life scores as measured by the QLQ-30 were not statistically significant.22 A Hospital in Perth has recently opened a clinic staffed by pleural specialists dedicated to diagnosis, treatment and management of patients with pleural disease. The clinic may offer patients faster access to services when symptoms reoccur as well as facilitate the follow-up and home care of individuals with MPE.8 Whilst IPCs may offer the benefit of shorter hospital stays, in some patients this benefit may not be realised, as due to underlying conditions or co-morbidities patients may have to remain in hospital. As a result, the benefits of IPCs should be assessed in the context of the overall management of the patient by a multidisciplinary team or order to provide the best care possible. One study has been completed investigating the use of the Pleurx® catheter in patients with pleural effusions who have a primary diagnosis of advanced congestive heart failure (CHF).23 2012 Summary of findings The peer-reviewed literature indicates that the Pleurx® catheter is relatively safe, improves symptoms for patients with MPE and may be associated with shorter hospital stays as compared to pleurodesis. When offered by a coordinated multi-disciplinary team dedicated to pleural services, in conjunction with appropriate follow-up and after care, in-dwelling pleural catheters may be integral to treatments strategies aiming to provide sustained symptomatic relief, with a focus on ambulatory care and minimal hospital stays. However there may be some situations in which shorter hospital stay may not be realised due to other underlying conditions or co-morbidities, and so the choice to use IPCs should be assessed in this context. 2012 HealthPACT assessment: Based on one RCT and a systematic review consisting of poor quality level IV evidence it is recommended that the Pleurx® catheter be monitored for 48 months. However, recently published evidence is available for the comparable Rocket Medical™ IPC, including the data from the trial in Western Australia, which may warrant further investigation.

PleurX® catheter system for malignant pleural effusions: Update July 2015 17 Appendix A Expert clinical opinion Clinical review was sought from two expert clinicians in the field, namely, a cardiac surgeon and a respiratory physician. Firstly, the clinicians highlighted that the Pleurx® catheter is indicated for patients presenting with MPE with or without trapped lung syndrome. However, patients who subsequently develop trapped lung syndrome requiring reintervention are not indicated for receiving the Pleurx® catheter. Secondly, it should be noted that insertion of an IPC such as the Pleurx® catheter should be done under ultrasound or X-ray guidance, in order to prevent complications associated with the incorrect insertion of the catheter. Situations can occur in which interventional radiologists and other qualified clinicians insert the Pleurx® catheter according to the product information leaflet, which specifies that the catheter should be inserted fully before the sheath is introduced. However, should a clinician fully insert the catheter ‘blindly’ without using ultrasound or X-ray guidance (according to the product information leaflet) inadvertent penetration of the heart and chest wall can occur resulting in significant complications and the need for corrective intervention by a cardiac surgeon.
