A 28-Day Multiple Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of K-757 and K-833 in Overweight/Obese Patients With Type 2 Diabetes Mellitus

Exclusion Criteria:
Has participated in another interventional investigational study within 30 days of the Screening Visit. The window will be derived from the date of the last study procedure and/or AE related to the study procedure in the previous study to the Screening Visit of the current study. If the subject received an investigational medication in the prior study, at least 5 half-lives (or longer if required by local regulations) must have passed between the last dose of the investigational product and the Screening Visit.
Is an employee or immediate family member (eg, spouse, parent, child, sibling) of the Sponsor or study site.
Has a history of multiple significant and/or any severe allergies (eg, food, drug, latex allergy) or has had an anaphylactic reaction or significant intolerance to prescription or nonprescription drugs or food.

Has a positive alcohol or drug screen at Screening or admission.
Has a positive pregnancy test.
Is a lactating/nursing female.
Has a positive test result for hepatitis B surface antigen, hepatitis C virus antibody, or human immunodeficiency antibody, at the Screening Visit. Note: Subjects with positive hepatitis B virus or hepatitis C virus serology may be enrolled if quantitative polymerase chain reaction for hepatitis B virus or hepatitis C virus ribonucleic acid is negative.
Does not meet study site COVID-19 admission/study participation restrictions.
Has a fever (>38oC).*
Had major surgery or donated or lost 1 unit of blood (approximately 500 mL) within 4 weeks prior to the Screening Visit.*
Is unable to refrain from the use of prohibited prescription or non-prescription drugs including vitamins, herbal and dietary supplements (including St John's Wort) within 7 days (or 14 days if the drug is a potential enzyme inducer) or 5 half-lives (whichever is longer) prior to the first dose of study medication through completion of study participation.
As detailed in Section 10.1, allowable concomitant medications may include HMG-CoA reductase inhibitors (statins), ≤2 permissible anti-hypertensive agents, postmenopausal hormone replacement therapy, and/or proton pump inhibitors (PPIs).
Has been on any GLP-1 receptor agonist, any dipeptidyl peptidase IV (DPP-4) inhibitor, or any approved or investigational medications known to cause weight loss in the prior 3 months.
Has a history of type 1 diabetes mellitus (T1DM) or a history of diabetic ketoacidosis or subject assessed by the investigator as possibly having T1DM.
Has a history of other specific types of other specific types of diabetes (e.g. genetic syndromes, secondary pancreatic diabetes, diabetes due to endocrinopathies, drug- or chemical-induced, and post organ transplant diabetes).
Has been treated with insulin or any other AHAs other than metformin within 4 weeks of screening or within 12 weeks of screening if the AHA was a thiazolidinedione (e.g., rosiglitazone, pioglitazone).
At Screening or Day -1 has a site fasting fingerstick glucose of >270 mg/dL.*
Has evidence or history of diabetic complications or significant end organ damage, eg, proliferative retinopathy and/or macular edema, eGFR (MDRD) ≤60 mL/min, diabetic neuropathy.

Is using or anticipates the need for using concomitant medications which are inhibitors of P-gp or BCRP or any prohibited medications from screening until the post study visit.
Has excessive consumption of alcohol within 6 months prior to screening (>14 drinks/week for men and >7 drinks/week for women, where l drink= 5 ounces [150 mL] of wine or 12 ounces [360 mL] of beer or 1.5 ounces [45 mL] of hard liquor) or use any of soft drugs(such as marijuana) within 3 months prior to Screening, or hard drugs (such as cocaine) within 6 months prior to Screening.
Is unwilling or unable to refrain from consuming alcohol from 7 days prior to the first dose of study medication through the completion of study participation.
Has a substance abuse disorder.
Had a previous major psychotic disorder.
Has a corrected QT interval to Fridericia's formula (QTcF) >450 milliseconds (msec) for males and >470 msec for females at screening or admission.
Has a mean value for triplicate semi-recumbent systolic blood pressure >160 millimeters of mercury (mmHg) and/or diastolic blood pressure (BP) >95 mmHg measured after at least 10 minutes at rest at the Screening Visit. Note: If a subject's BP is exclusionary on the first triplicate assessment at the Screening visit, they may have 1 repeat triplicate BP assessment at that visit, after another rest of at least 10 minutes, to qualify for the study.
If a subject's BP is exclusionary at screening but the investigator feels that BP is likely to be below the exclusionary thresholds at admission (Day -2), this criterion can be re-assessed at admission. Adjustment of doses of anti-hypertensives already being taken at screening is permissible, but initiation of new agents is not permissible. For subjects whose BP is exclusionary at Screening and at the first triplicate assessment on Day -2, triplicate assessments can be repeated up to twice on Day -2, as needed.
Has alanine aminotransferase or aspartate aminotransferase (ALT or AST) of >1.0X upper limit of normal (ULN) or total bilirubin >1.2X ULN (isolated bilirubin >1.2X ULN is acceptable if bilirubin is fractionated, and direct bilirubin is within the laboratory normal range) at Screening or admission. (Note: Subjects who do not meet this criterion at Screening or at admission may not be rescreened/retested).
Has serum amylase or lipase >1.2X the ULN at the Screening Visit.
Has a recent history (within past 3 years) or current diagnosis of any of the following GI (gastro-intestinal) related diseases: intestinal obstruction, GI perforation, GI motility disorders, adhesions, Clostridium difficile colitis or have had recent unexplained GI bleeding within 3 months prior to screening.
Has any history of pancreatitis (acute or chronic), gastroparesis, ischemic colitis, inflammatory bowel disease (IBD), celiac disease, irritable bowel syndrome (IBS), or colitis.

note - *Subject may be included if they are able to return to the site within 7 days of initial screening and the exclusion criterion is no longer met.
