Cispharm Injection

Cisplatin Injection is indicated as therapy to be employed as follows: Metastatic Testicular Tumors In established combination therapy with other approved chemotherapeutic agents in patients with metastatic testicular tumors who have already received appropriate surgical and/or radio therapeutic procedures. Metastatic Ovarian Tumors In established combination therapy with other approved chemotherapeutic agents in patients with metastatic ovarian tumors who have already received appropriate surgical and/or radiotherapeutic procedures. An established combination consists of Cisplatin and cyclophosphamide. Cisplatin Injection, as a single agent, is indicated as secondary therapy in patients with metastatic ovarian tumors refractory to standard chemotherapy who have not previously received Cisplatin Injection therapy. Advanced Bladder Cancer Cisplatin Injection is indicated as a single agent for patients with transitional cell bladder cancer which is no longer amenable to local treatments, such as surgery and/or radiotherapy.

Boxed warning. Cisplatin should be administered under the supervision of a qualified physician experienced in the use of cancer chemotherapeutic agents. Appropriate management of therapy and complications is possible only when adequate diagnostic and treatment facilities are readily available. Cumulative renal toxicity associated with Cisplatin is severe. Other major dose-related toxicities are myelosuppression, nausea, and vomiting. Ototoxicity, which may be more pronounced in children, and is manifested by tinnitus, and/or loss of high frequency hearing and occasionally deafness, is significant. Anaphylactic-like reactions to Cisplatin have been reported. Facial edema, bronchoconstriction, tachycardia, and hypotension may occur within minutes of Cisplatin administration. Epinephrine, corticosteroids, and antihistamines have been effectively employed to alleviate symptoms (see WARNINGS and ADVERSE REACTIONS ). Exercise caution to prevent inadvertent Cisplatin overdose. Doses greater than 100 mg/m 2 /cycle once every 3 to 4 weeks are rarely used. Care must be taken to avoid inadvertent Cisplatin overdose due to confusion with carboplatin or prescribing practices that fail to differentiate daily doses from total dose per cycle. Cisplatin produces cumulative nephrotoxicity which is potentiated by aminoglycoside antibiotics. The serum creatinine, blood urea nitrogen (BUN), creatinine clearance, and magnesium, sodium, potassium, and calcium levels should be measured prior to initiating therapy, and prior to each subsequent course. At the recommended dosage, Cisplatin should not be given more frequently than once every 3 to 4 weeks (see ADVERSE REACTIONS ). Elderly patients may be more susceptible to nephrotoxicity (see PRECAUTIONS, Geriatric Use ). There are reports of severe neuropathies in patients in whom regimens are employed using higher doses of Cisplatin or greater dose frequencies than those recommended. These neuropathies may be irreversible and are seen as paresthesias in a stocking-glove distribution, areflexia, and loss of proprioception and vibratory sensation. Elderly patients may be more susceptible to peripheral neuropathy (see PRECAUTIONS, Geriatric Use ). Loss of motor function has also been reported. These reactions have occurred within minutes of administration to patients with prior exposure to Cisplatin, and have been alleviated by administration of epinephrine, corticosteroids, and antihistamines. Cisplatin can commonly cause ototoxicity which is cumulative and may be severe. Audiometric testing should be performed prior to initiating therapy and prior to each subsequent dose of drug (see ADVERSE REACTIONS ). Abridged from the full prescribing information.

Nephrotoxicity Dose-related and cumulative renal insufficiency, including acute renal failure, is the major dose-limiting toxicity of Cisplatin. Renal toxicity has been noted in 28% to 36% of patients treated with a single dose of 50 mg/m 2. It is first noted during the second week after a dose and is manifested by elevations in BUN and creatinine, serum uric acid and/or a decrease in creatinine clearance. Renal toxicity becomes more prolonged and severe with repeated courses of the drug. Renal function must return to normal before another dose of Cisplatin can be given. Elderly patients may be more susceptible to nephrotoxicity (see PRECAUTIONS, Geriatric Use ). Impairment of renal function has been associated with renal tubular damage. The administration of Cisplatin using a 6 hour to 8 hour infusion with intravenous hydration, and mannitol has been used to reduce nephrotoxicity. However, renal toxicity still can occur after utilization of these procedures. Ototoxicity has been observed in up to 31% of patients treated with a single dose of Cisplatin 50 mg/m 2, and is manifested by tinnitus and/or hearing loss in the high frequency range (4,000 to 8,000 Hz). The prevalence of hearing loss in children is particularly high and is estimated to be 40 to 60%. Decreased ability to hear normal conversational tones may occur. Deafness after the initial dose of Cisplatin has been reported. Ototoxic effects may be more severe in children receiving Cisplatin. Hearing loss can be unilateral or bilateral and tends to become more frequent and severe with repeated Cisplatin doses. It is unclear whether Cisplatin-induced ototoxicity is reversible. Vestibular toxicity has also been reported. Ototoxic effects may be related to the peak plasma concentration of Cisplatin. Ototoxicity can occur during treatment or be delayed. Audiometric monitoring should be performed prior to initiation of therapy, prior to each subsequent dose, and for several years post therapy. The risk of ototoxicity may be increased by prior or simultaneous cranial irradiation, and may be more severe in patients less than 5 years of age, patients being treated with other ototoxic drugs (e.g., aminoglycosides and vancomycin), and in patients with renal impairment. Genetic factors (e.g., variants in the thiopurine S-methyltransferase [TPMT] gene) may contribute to Cisplatin-induced ototoxicity; although this association has not been consistent across populations and study designs. Hematologic Myelosuppression occurs in 25% to 30% of patients treated with Cisplatin. Abridged from the full prescribing information.
