Exclusion Criteria: * Is poorly compliant with the currently prescribed diabetes regimen, as determined by the Investigator; * Is poorly compliant with prescribed self-monitoring of blood glucose, as determined by the Investigator; * Is currently taking or has taken sulfonylureas within the last 2 months; * Has a BMI greater than 40 kg/m2; * Has experienced recurrent severe hypoglycemia (\> 2 episodes) requiring assistance during the past 6 months; * Has existing dermal irritation/inflammation over the abdominal area that may interfere with use of PaQ, as determined by the Investigator; * Has known clinically significant hypersensitivity to skin adhesives; * Is female and if of child-bearing potential, is pregnant, lactating, or planning to become pregnant; * Is currently being treated with or expected to require or undergo treatment with systemic steroids by oral, intravenous, or intramuscular route (inhaled with low systemic exposure is permitted); * Currently abuses drugs or alcohol or has a history of abuse that in the Investigator's opinion would cause the individual to be non-compliant; * Has received any investigational drug within 1 month; * Has donated blood within 30 days; * Has any significant medical condition (including current or past history of cardiovascular disease), laboratory findings, or medical history that in the Investigator's opinion may affect successful completion of the study and/or personal well-being; * Is an immediate family member (spouse, parent, child, or sibling) of personnel directly affiliated with the study at the investigative site, or is personally directly affiliated with the study at the investigative site.
