CLINICAL NEWS New Biosensor Provides Complete Blood Cell Count Test Results in Minutes Researchers from the University of Illinois at Urbana-Champaign have developed a new biosensor based on a microfluidic biochip that can count blood cells electrically using just a drop of blood, potentially replacing the standard protocol for obtaining a complete blood count (CBC), according to results published in Technology. The CBC is one of the most commonly ordered blood tests, and standard practice includes using a hematology analyzer, which requires trained technicians and physical sample transporta- Table 7: Percent Incidence of Clinically Relevant Grade 3/4* Laboratory Abnormalities Patient Population Resistant or Intolerant Ph+ Newly Diagnosed Ph+ CML-CP CML-CP CML-AP TASIGNA Imatinib TASIGNA TASIGNA 300 mg 400 mg 400 mg 400 mg twice-daily once-daily twice-daily twice-daily N=279 N=280 N=321 N=137 (%) (%) (%) (%) Biochemistry Parameters Elevated creatinine 0 <1 <1 <1 *NCI Common Terminology Criteria for Adverse Events, version 3.0 1CML-CP: Thrombocytopenia: 12% were grade 3, 18% were grade 4 2CML-CP: Neutropenia: 16% were grade 3, 15% were grade 4 3CML-AP: Thrombocytopenia: 11% were grade 3, 32% were grade 4 4CML-AP: Neutropenia: 16% were grade 3, 26% were grade 4 Elevated total cholesterol (all grades) occurred in 28% (Tasigna 300 mg bid) and 4% (imatinib). Elevated triglycerides (all grades) occurred in 12% and 8% of patients in the Tasigna and imatinib arms, respectively. Hyperglycemia (all grades) occurred in 50% and 31% of patients in the Tasigna and imatinib arms, respectively. Most common biochemistry laboratory abnormalities (all grades) were alanine aminotransferase increased (72%), blood bilirubin increased (59%), aspartate aminotransferase increased (47%), lipase increased (28%), blood glucose increased (50%), blood cholesterol increased (28%), and blood triglyceride increased (12%). 6.2 Additional Data from Clinical Trials The following adverse drug reactions were reported in patients in the Tasigna clinical studies at the recommended doses. These adverse drug reactions are ranked under a heading of frequency, the most frequent first using the following convention: common (≥1% and <10%), uncommon (≥0.1% and <1%), and unknown frequency (single events). For laboratory abnormalities, very common events (≥10%), which were not included in Tables 5 and 6, are also reported. These adverse reactions are included based on clinical relevance and ranked in order of decreasing seriousness within each category, obtained from 2 clinical studies: 1. Newly diagnosed Ph+ CML-CP 60 month analysis and, 2. Resistant or intolerant Ph+ CML-CP and CMP-AP 24 months’ analysis. Infections and Infestations: Common: folliculitis. Uncommon: pneumonia, bronchitis, urinary tract infection, candidiasis (including oral candidiasis). Unknown frequency: sepsis, subcutaneous abscess, anal abscess, furuncle, tinea pedis. Neoplasms Benign, Malignant, and Unspecified: Common: skin papilloma. Unknown frequency: oral papilloma, paraproteinemia. Blood and Lymphatic System Disorders: Common: leukopenia, eosinophilia, febrile neutropenia, pancytopenia, lymphopenia. Unknown frequency: thrombocythemia, leukocytosis. Immune System Disorders: Unknown frequency: hypersensitivity. Endocrine Disorders: Uncommon: hyperthyroidism, hypothyroidism. Unknown frequency: hyperparathyroidism secondary, thyroiditis. Metabolism and Nutrition Disorders: Very Common: hypophosphatemia. Common: electrolyte imbalance (including hypomagnesemia, hyperkalemia, hypokalemia, hyponatremia, hypocalcemia, hypercalcemia, hyperphosphatemia), diabetes mellitus, hyperglycemia, hypercholesterolemia, hyperlipidemia, hypertriglyceridemia. Uncommon: gout, dehydration, increased appetite. Unknown frequency: hyperuricemia, hypoglycemia. Psychiatric Disorders: Common: depression, anxiety. Unknown frequency: disorientation, confusional state, amnesia, dysphoria. Nervous System Disorders: Common: peripheral neuropathy, hypoesthesia, paresthesia. Uncommon: intracranial hemorrhage, ischemic stroke, transient ischemic attack, cerebral infarction, migraine, loss of consciousness (including syncope), tremor, disturbance in attention, hyperesthesia. Unknown frequency: basilar artery stenosis, brain edema, optic neuritis, lethargy, dysesthesia, restless legs syndrome. Eye Disorders: Common: eye hemorrhage, eye pruritus, conjunctivitis, dry eye (including xerophthalmia). Uncommon: vision impairment, vision blurred, visual acuity reduced, photopsia, hyperemia (scleral, conjunctival, ocular), eye irritation, conjunctival hemorrhage. Unknown frequency: papilloedema, diplopia, photophobia, eye swelling, blepharitis, eye pain, chorioretinopathy, conjunctivitis allergic, ocular surface disease. Ear and Labyrinth Disorders: Common: vertigo. Unknown frequency: hearing impaired, ear pain, tinnitus. “This new technology will be most useful in resource-limited settings, where laboratory tests are often inaccessible due to cost.” —RASHID BASHIR, PhD Cardiac Disorders: Common: angina pe 7F
