Details and patient eligibility


The purpose of this study is to compare LY2605541 and human insulin isophane suspension (NPH) using the following measures for participants treated for up to 26 weeks: * Change in participants' overall blood sugar control * The rate of night time low blood sugar episodes * The number of participants that reach blood sugar targets without low night time blood sugar episodes * The total number of low blood sugar episodes reported

  • Have active or untreated cancer, have been in remission from clinically significant cancer(other than basal cell or squamous cell skin cancer) for less than 5 years, or are at increased risk for developing cancer or a recurrence of cancer in the opinion of the investigator
  • Are receiving chronic (lasting longer than 14 consecutive days) systemic glucocorticoid therapy (excluding topical, intranasal, intraocular, and inhaled preparations) or have received such therapy within the 8 weeks immediately preceding screening

None (Open label)

641 participants in 2 patient groups

Experimental group
Administered by subcutaneous (SC) injection once daily in the morning or at bedtime. Initial dose is 10 units (or less for some of the participants in Korea) and is adjusted weekly based on Fasting Blood Glucose (FBG). LY2605541 will be given alone or in combination with up to 3 pre-study oral antihyperglycemic medications [OAM(s)] whose use is not excluded in combination with insulin. Treatment may last up to 26 weeks.
Drug: Oral Antihyperglycemic Medications (OAM)
Drug: LY2605541
Human Insulin NPH
Active Comparator group
Administered by SC injection once daily at bedtime. Initial dose is 10 units (or less for some of the participants in Korea) and is adjusted weekly based on FBG. Human insulin NPH will be used alone or in combination with up to 3 pre-study OAM(s) whose use is not excluded in combination with insulin. Treatment may last up to 26 weeks. Some participants who are unable to achieve glycemic control after at least 12 weeks of treatment with a single injection of NPH may be asked to add a second injection prior to the morning meal.
