Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse events that appear to be related to drug use and for approximating rates.
Extraneal (icodextrin peritoneal dialysis solution) was originally studied in controlled clinical trials of 493 patients with end-stage renal disease who received a single daily exchange of Extraneal (icodextrin peritoneal dialysis solution) for the long dwell (8-to 16- hours). There were 215 patients exposed for at least 6 months and 155 patients exposed for at least one year. The population was 18-83 years of age, 56% male and 44% female, 73% Caucasian, 18% Black, 4% Asian, 3% Hispanic, and it included patients with the following comorbid conditions: 27% diabetes, 49% hypertension and 23% hypertensive nephropathy.
Rash was the most frequently occurring Extraneal (icodextrin peritoneal dialysis solution) -related adverse event (5.5%, Extraneal (icodextrin peritoneal dialysis solution) ; 1.7% Control). Seven patients on Extraneal (icodextrin peritoneal dialysis solution) discontinued treatment due to rash, and one patient on Extraneal (icodextrin peritoneal dialysis solution) discontinued due to exfoliative dermatitis. The rash typically appeared within the first three weeks of treatment and resolved with treatment discontinuation or, in some patients, with continued treatment.
Female patients reported a higher incidence of skin events, including rash, in both Extraneal (icodextrin peritoneal dialysis solution) and dextrose control treatment groups.
Table 1 shows the adverse events reported in these clinical studies, regardless of causality, occurring in ≥ 5% of patients and more common on Extraneal (icodextrin peritoneal dialysis solution) than control.
Table 1 - Adverse Experiences in ≥ 5 % of Patients and More
Common on EXTRANEAL (icodextrin peritoneal dialysis solution)
|N = 493||N = 347|
|Upper respiratory infection||15%||13%|
Adverse reactions reported with an incidence of > 5% and at least as common on dextrose control included pain, asthenia, exit site infection, infection, back pain, hypotension, diarrhea, vomiting, nausea/vomiting, anemia, peripheral edema, hypokalemia, hyperphosphatemia, hypoproteinemia, hypervolemia, arthralgia, dizziness, dyspnea, skin disorder, pruritis.
Additional adverse events occurring at an incidence of < 5% and that may or may not have been related to Extraneal (icodextrin peritoneal dialysis solution) include: pain on infusion, abdominal enlargement, cloudy effluent, ultrafiltration decrease, postural hypotension, heart failure, hyponatremia, hypochloremia, hypercalcemia, hypoglycemia, alkaline phosphatase increase, SGPT increase, SGOT increase, cramping, confusion, lung edema, facial edema, exfoliative dermatitis, eczema, vesicobullous rash, maculopapular rash, erythema multiforme. All reported events are included in the list except those already listed in Table 1 or the following two paragraphs, those not plausibly associated with Extraneal (icodextrin peritoneal dialysis solution) , and those that were associated with the condition being treated or related to the dialysis procedure.
Extraneal (icodextrin peritoneal dialysis solution) was additionally studied in a subpopulation of 92 high average/high transporter APD patients in a two-week controlled clinical trial where patients received a single daily exchange of Extraneal (icodextrin peritoneal dialysis solution) (n=47) or dextrose control (n=45) for the long dwell (14 ±2 hours). Consistent with the data reported in the original trials of Extraneal (icodextrin peritoneal dialysis solution) , rash was the most frequently occurring event.
Adverse events common to the peritoneal dialysis, including peritonitis, infection around the catheter, fluid and electrolyte imbalance, and pain, were observed at a similar frequency with Extraneal and Controls (See PRECAUTIONS).
Changes in Alkaline Phosphatase and Serum Electrolytes
An increase in mean serum alkaline phosphatase has been observed in clinical studies of ESRD patients receiving Extraneal (icodextrin peritoneal dialysis solution) . No associated increases in other liver chemistry tests were observed. Serum alkaline phosphatase levels did not show progressive increase over a 12-month study period. Levels returned to normal approximately two weeks after discontinuation of Extraneal (icodextrin peritoneal dialysis solution) .
Decreases in serum sodium and chloride have been observed in patients using Extraneal (icodextrin peritoneal dialysis solution) . The declines in serum sodium and chloride may be related to dilution resulting from the presence of icodextrin metabolites in plasma. Although these decreases have been small and clinically unimportant, monitoring of patients' serum electrolyte levels as part of routine blood chemistry testing is recommended.
The following adverse reactions have been identified during post-approval use of Extraneal (icodextrin peritoneal dialysis solution) . Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to estimate their frequency reliably or to establish a causal relationship to drug exposure. Adverse reactions are listed by MedDRA System Order Class (SOC), followed by Preferred Term in order of severity.

No clinical drug interaction studies were performed. No evaluation of Extraneal (icodextrin peritoneal dialysis solution) 's effects on the cytochrome P450 system was conducted. As with other dialysis solutions, blood concentrations of dialyzable drugs may be reduced by dialysis. Dosage adjustment of concomitant medications may be necessary. In patients using cardiac glycosides (digoxin and others), plasma levels of calcium, potassium and magnesium must be carefully monitored.
A clinical study in 6 insulin-dependent diabetic patients demonstrated no effect of Extraneal (icodextrin peritoneal dialysis solution) on insulin absorption from the peritoneal cavity or on insulin's ability to control blood glucose when insulin was administered intraperitoneally with Extraneal (icodextrin peritoneal dialysis solution) . However, appropriate monitoring (See Drug/Laboratory Test Interactions) of blood glucose should be performed when initiating Extraneal (icodextrin peritoneal dialysis solution) in diabetic patients and insulin dosage should be adjusted if needed (See PRECAUTIONS).
No human drug interaction studies with heparin were conducted. In vitro studies demonstrated no evidence of incompatibility of heparin with Extraneal (icodextrin peritoneal dialysis solution) .
No human drug interaction studies with antibiotics were conducted. In vitro studies evaluating the minimum inhibitory concentration (MIC) of vancomycin, cefazolin, ampicillin, ampicillin/flucoxacillin, ceftazidime, gentamicin, and amphotericin demonstrated no evidence of incompatibility of these antibiotics with Extraneal. (See DOSAGE AND ADMINISTRATION)
Drug/Laboratory Test Interactions
Blood glucose measurement must be done with a glucose-specific method to prevent maltose interference with test results. Falsely elevated glucose levels have been observed with blood glucose monitoring devices and test strips that use glucose dehydrogenase pyrroloquinolinequinone (GDH-PQQ), glucose-dye-oxidoreductase (GDO), and some glucose dehydrogenase flavin-adenine nucleotide (GDH-FAD)-based methods. GDH-PQQ,glucose-dye-oxidoreductase, and some GDH-FAD-based methods must not be used to measure glucose levels in patients administered Extraneal (See WARNINGS).
An apparent decrease in serum amylase activity has been observed in patients administered Extraneal. Preliminary investigations indicate that icodextrin and its metabolites interfere with enzymatic-based amylase assays, resulting in inaccurately low values. This should be taken into account when evaluating serum amylase levels for diagnosis or monitoring of pancreatitis in patients using Extraneal (icodextrin peritoneal dialysis solution) .
