Reporting Groups
  Description
LY2599506 Participants received up to 4 capsules by mouth (po), twice daily (BID), in combinations of 50 milligram (mg) or 100 mg capsules of LY2599506 or matching placebo capsules. (Each dose contained at least 1 capsule of active drug.) LY2599506 was administered, based on predefined glycemic targets, in escalating doses from 100 mg/day up to 800 mg/day.
Glyburide Participants received up to 4 capsules po BID in combinations of 2.5-mg capsules of Glyburide or matching placebo capsules. (Each dose contained at least 1 capsule of active drug.) Glyburide was administered, based on predefined glycemic targets, in escalating doses from 5 mg/day up to 20 mg/day.

Measure Type Secondary
Measure Title 30-day Adjusted Rates of Self-reported Hypoglycemic Episodes Overall
Measure Description Hypoglycemia: any time a participant experienced a sign/symptom associated with hypoglycemia or had blood glucose <70 milligrams per deciliter (mg/dL) (3.9 millimoles per liter [mmol/L]). The 30-day adjusted rate=(total number of episodes between 2 time intervals/number of days between intervals) X 30 days. Study GMAJ was terminated after enrolling 38 participants. Given small sample size overall and per treatment arm, numerical summaries and statistical comparisons are not appropriate and may be scientifically/clinically misleading; therefore, this outcome measure is not presented.
Time Frame Baseline through 16 weeks  
Safety Issue Yes

Certain Agreements:  
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Since Study GMAJ was terminated after enrolling only 38 participants with just 1 participant completing 12 weeks of treatment, only disposition, demographics, and safety data are reported.
