For Healthcare Professionals

Applies to daptomycin: intravenous powder for injection

General

In Phase 3 complicated skin and skin structure infection trials, daptomycin (the active ingredient contained in Cubicin) was discontinued in 2.8% of patients due to a side effect, while comparator was discontinued in 3% of patients. In the Staphylococcus aureus bacteremia/endocarditis trial, daptomycin was discontinued in 16.7% of patients due to a side effect, while comparator was discontinued in 18.1% of patients.

In Phase 3 community-acquired pneumonia trials, the death rate and rates of serious cardiorespiratory side effects were higher with daptomycin than comparator due to lack of therapeutic efficacy.

Musculoskeletal

In clinical studies, 0.2% of patients had symptoms of muscle pain or weakness associated with CPK elevations to greater than 4 times ULN. After discontinuation of daptomycin (the active ingredient contained in Cubicin) CPK returned to normal within 7 to 10 days and symptoms resolved within 3 days.

A 45-year-old female with refractory acute myeloid leukemia was admitted to the blood and marrow transplant unit for a second attempt to induce remission with myeloablative chemotherapy of high-dose cytarabine. Two months prior, the patient's first course of induction therapy was complicated by neutropenic fever and vancomycin- resistant Enterococcus faecium (VRE) bacteremia that was treated with linezolid for 14 days. The patient was also receiving aztreonam, levofloxacin, acyclovir, amphotericin B lipid complex, and azithromycin. Once her clinical status stabilized, she was transferred from the intensive care unit (ICU) back to the blood and marrow transplant unit. After receiving 8 of 12 scheduled doses of cytarabine, the patient required readmission to the medical ICU due to a decrease in mental status, supraventricular tachycardia, and hypotension. Cultures of blood and urine samples at the time of her transfer showed VRE with intermediate resistance to linezolid. The patient, who was neutropenic at this time, was started on IV daptomycin 550 mg (6 mg/kg) every 24 hours. The patient's baseline CPK was 108 units/L and serum creatinine level was 0.8 mg/dL. Over the following 7 days, the patient's CPK level gradually increased, and on day 10 of daptomycin therapy, her CPK level was 996 units/L, blood urea nitrogen level (BUN) was 73 mg/dL, and serum creatinine level was 1.9 mg/dL. To evaluate for rhabdomyolysis, urine myoglobin was measured and reported at 30,890 ng/mL. Rhabdomyolysis was diagnosed based on increased CPK and urine myoglobin level in a patient with acute renal failure. Daptomycin was discontinued and the patient was started on treatment for rhabdomyolysis. Despite aggressive hydration and diuresis, CPK and urine myoglobin levels continued to increase up to 5350 units/L and 47,166 ng/mL, respectively. Over 2 weeks, the patient's CPK and urine myoglobin levels slowly resolved. The final CPK and urine myoglobin levels measured were 3395 units/L and 451 ng/mL, respectively.

In another case, a 53-year-old African-American female with a history of hypertension, diabetes mellitus, and peripheral vascular disease was admitted to the hospital and an MRI revealed L5-S1 discitis and osteomyelitis. After an 8-week course of empirical antibiotic therapy with vancomycin and levofloxacin, an open biopsy was performed. Specimens from the biopsy cultured positive for Torulopsis glabrata, VRE, and methicillin-resistant S aureus (MRSA) and the patient was started on daptomycin 360 mg (6 mg/kg) IV as a single daily dose and voriconazole 250 mg twice daily. Ten days after the start of daptomycin therapy, the patient developed generalized muscular weakness that progressed to the point she was unable to get out of bed. The patient then developed nonoliguric acute renal failure with a serum creatinine of 27 mg/mL up from baseline of 9 mg/mL. A CPK level drawn was elevated to 21,243 units/L and was associated with elevated levels aspartate aminotransferase (AST) 375 units/L, alanine aminotransferase (ALT) 219 units/L, and lactate dehydrogenase (LDH) 666 units/L. Urinalysis was positive for hemoglobin, myoglobin, and red blood cells which conferred a diagnosis of acute renal failure secondary to daptomycin-induced rhabdomyolysis. After daptomycin was discontinued and IV fluid was administered to alkalinize the urine, renal function, CPK, and liver function tests returned to baseline as well as dissipation of muscular weakness. Myoglobin, hemoglobin, and the red blood cells disappeared from urine as well.

In another similar case, a 52-year-old male with a history hepatitis C, IV drug abuse, idiopathic thrombocytopenia, and hyperlipidemia was admitted to the hospital and an MRI revealed findings compatible with L3-L4 discitis and osteomyelitis. He was started on vancomycin but it was discontinued after a rash developed. Daptomycin was started at 500 mg (6.5 mg/kg) IV as a single daily dose. The patient was also on simvastatin; however, it was discontinued prior to initiation of daptomycin therapy. After nine days into the course of daptomycin therapy, the patient developed generalized muscle weakness progressing to the point where he was unable to get out of bed. The patient's CPK rose to 20,771 units/L from a baseline of 102 units/L. AST 239 units/L and ALT 40 units/L were elevated from baseline and alkaline phosphatase was elevated to 118 units/L. Daptomycin was discontinued and the patient was admitted to the ICU for close monitoring and hydration. The patient slowly improved and recovered all muscle strength and within 2 weeks his enzymes returned to baseline.
