Pazenir

Pazenir should only be administered under the supervision of a qualified oncologist in units specialised in the administration of cytotoxic agents. It should not be substituted for or with other paclitaxel formulations. Posology Breast cancer The recommended dose of Pazenir is 260 mg/m2 administered intravenously over 30 minutes every 3 weeks.

Dose adjustments during treatment of breast cancer Patients who experience severe neutropenia (neutrophil count < 500 cells/mm3for a week or longer) or severe sensory neuropathy during Pazenir therapy should have the dose reduced to 220 mg/m2 for subsequent courses.

Following recurrence of severe neutropenia or severe sensory neuropathy, 3 additional dose reduction should be made to 180 mg/m2. Pazenir should not be administered until neutrophil counts recover to >1500 cells/mm3. For Grade 3 sensory neuropathy, withhold treatment until resolution to Grade 1 or 2, followed by a dose reduction for all subsequent courses.

Pancreatic adenocarcinoma The recommended dose of Pazenir in combination with gemcitabine is 125 mg/m2 administered intravenously over 30 minutes on Days 1, 8 and 15 of each 28-day cycle. The concurrent recommended dose of gemcitabine is 1000 mg/m2 administered intravenously over 30 minutes immediately after the completion of Pazenir administration on Days 1, 8 and 15 of each 28-day cycle.

Summary of the safety profile The most common clinically significant adverse reactions associated with the use of human serum albumin-paclitaxel nanoparticles have been neutropenia, peripheral neuropathy, arthralgia/myalgia and gastrointestinal disorders.

Tabulated list of adverse reactions Table 6 lists adverse reactions associated with human serum albumin-paclitaxel nanoparticles monotherapy at any dose in any indication during clinical trials (N = 789), human serum albumin- paclitaxel nanoparicles in combination with gemcitabine for pancreatic adenocarcinoma from the phase III clinical trial (N = 421), human serum albumin-paclitaxel nanoparticles in combination with carboplatin for non-small cell lung cancer from the phase III clinical trial (N = 514) and from post- marketing use.

Frequencies are defined as: very common (≥1/10), common (≥1/100 to <1/10), uncommon (≥1/1,000 to <1/100), rare (≥1/10,000 to <1/1,000), very rare (<1/10,000), not known (cannot be estimated from the available data). Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness.

2). It should not be substituted for or with other paclitaxel formulations. Hypersensitivity Rare occurrences of severe hypersensitivity reactions, including very rare events of anaphylactic reactions with fatal outcome, have been reported.

If a hypersensitivity reaction occurs, the medicinal product should be discontinued immediately, symptomatic treatment should be initiated, and the patient should not be rechallenged with paclitaxel. Haematology Bone marrow suppression (primarily neutropenia) occurs frequently with human serum albumin- paclitaxel nanoparticles.

Neutropenia is dose-dependent and a dose-limiting toxicity. Frequent monitoring of blood cell counts should be performed during Pazenir therapy. 2). Neuropathy Sensory neuropathy occurs frequently with human serum albumin-paclitaxel nanoparticles, although development of severe symptoms is less common.

The occurrence of Grade 1 or 2 sensory neuropathy does not generally require dose reduction. 2). For combination use of Pazenir and gemcitabine, if Grade 3 or higher peripheral neuropathy develops, withhold Pazenir; continue treatment with gemcitabine at the same dose.

2). 2). Sepsis Sepsis was reported at a rate of 5% in patients with or without neutropenia who received human serum albumin-paclitaxel nanoparticles in combination with gemcitabine. Complications due to the underlying pancreatic cancer, especially biliary obstruction or presence of biliary stent, were identified as significant contributing factors.

If a patient becomes febrile (regardless of neutrophil count), initiate treatment with broad spectrum antibiotics. 2). Pneumonitis Pneumonitis occurred in 1% of patients when human serum albumin-paclitaxel nanoparticles was used as monotherapy and in 4% of patients when when human serum albumin-paclitaxel nanoparticles were used in combination with gemcitabine.

Closely monitor all patients for signs and symptoms of pneumonitis. 2). Hepatic impairment Because the toxicity of paclitaxel can be increased with hepatic impairment, administration of Pazenir in patients with hepatic impairment should be performed with caution.
