A Randomized, Double-Blind, Placebo-Controlled Multicenter Phase 2 Study to Evaluate the Safety, Efficacy and Tolerability of Ofirnoflast (HT-6184) and Semaglutide in Obese or Overweight Participants With Type 2 Diabetes Mellitus (T2DM)

The purpose of this study is to evaluate the efficacy and safety of ofirnoflast in combination with semaglutide in comparison to semaglutide alone in obese participants with T2DM.

Inclusion: Participant must be 18 to 65 years of age inclusive, at the time of signing the informed consent; Capable of giving signed informed consent as described in Appendix 1 which includes compliance with the requirements and restrictions listed in the ICF and in this protocol; BMI between 27 kg/m2 and 40 kg/m2; Stable body weight (± 5 kg) within 90 days of screening, and body weight <150 kg; HbA1c is 7.5-10.5% at screening; Established diagnosis of T2DM; Receiving a stable 1mg SC q1wk dose of semaglutide (Ozempic®) for ≥ 90 days prior to signing informed consent; Females must meet one of the following:; Postmenopausal (>45 years of age with amenorrhea for at least 12 months, without using exogenous hormonal contraception and with FSH ≥ 40 IU/L); Surgically sterile (hysterectomy, bilateral salpingectomy; oophorectomy) for at least 6 months; Using a double contraception including a barrier method (condom, diaphragm, or occlusive cap) and a highly effective method of birth control, which includes the following:; Established use (i.e. at least 90 days prior to signing of ICF) of combined (estrogen and progestogen) oral, intravaginal, or transdermal hormonal contraceptive associated with inhibition of ovulation ii. Established use (i.e. at least 90 days prior to signing of ICF) of progestogen-only oral, injectable, or implantable hormonal contraceptive associated with inhibition of ovulation iii. Established use (i.e. at least 90 days prior to signing of ICF) of an intrauterine device (IUD) or intrauterine hormone-releasing system (IUS) iv. Bilateral tubal occlusion completed at least 90 days prior to signing of ICF d. Vasectomized partner with the appropriate post-vasectomy documentation of the absence of spermatozoa in the ejaculate. Participant must provide documentation before the first dose of ofirnoflast (study day 1); Sexual abstinence, when this is in line with the preferred and usual lifestyle of the participant; Male participants who are sexually active with a woman of childbearing potential must agree to use a double contraception including a barrier method (male condom) and a highly effective method of contraception (highly effective methods of contraception are listed above) during the study and for 30 days after the last dose of ofirnoflast/ placebo; In the case of WOCBP, participants must have a negative serum pregnancy test (β-human chorionic gonadotropin [β-hCG]) at screening and negative urine pregnancy tests on first day of dosing and at each study visit; Able to comply with the study procedures in the view of the Investigator.

Exclusion: Any prescription or over-the-counter medications intended for weight loss within 6 months of screening, excluding semaglutide; Use of other investigational drugs at the time of screening or within 30 days or 5 half-lives prior to signing of the ICF, whichever is longer, or longer if required by local regulations; Previous or current diagnosis of Type 1 diabetes mellitus (T1DM) or current gestational diabetes; Previous bariatric surgery, liposuction, or planned weight loss surgery; Undergone any major surgery within 8 weeks prior to study entry or will require major surgery during the study that, in the opinion of the Investigator, would pose an unacceptable risk to the participant; Planning elective surgery during the study duration; History or evidence of any other clinically significant concomitant disorder, condition or disease that, according to the Investigator's and medical monitor's (if consulted) judgment, would pose a risk to participant safety or interfere with the study evaluation, procedures, completion or interpretation of data; Blood donation within the last month before study day 1 (first dose of ofirnoflast or placebo); History of, or known hypersensitivity to, monoclonal antibody drugs or a contraindication to semaglutide (e.g. Ozempic® or Wegovy®); History of diabetic ketoacidosis (within 90 days of screening), or proliferative or severe retinopathy (i.e., retinopathy requiring acute treatment); Personal or within first-degree relative family history of medullary thyroid cancer or multiple endocrine neoplasia type 2; Current or history of clinically significant (per Investigator's judgment) liver or biliary disease or significantly abnormal LFT at screening (see above); Current acute or chronic self-reported HCV and/or HBV infection; Prior history of malignancy (including breast cancer, lymphoma, leukemia) within the past 5 years except for cervical carcinoma in situ that has been completely resected with no evidence of recurrence or metastatic disease for at least 12 months or cured basal cell carcinoma with no evidence of recurrence for at least 12 months; History of a major organ transplant (e.g. kidney, heart, liver, lung) or hematopoietic stem cell/ bone marrow transplant; History of lymphoproliferative disease or signs/ symptoms suggestive of possible lymphoproliferative disease, including splenomegaly of lymphadenopathy; History or current moderate to severe congestive heart failure (New York Heart Association class III or IV), or within the last 6 months, a cerebrovascular accident, myocardial infarction, unstable angina, unstable arrhythmia or any other cardiovascular condition which, in the opinion of the Investigator, would put the participant at risk by participation in the study; Inherited or acquired thrombophilia and/ or current or history of thromboembolic events/ disease; Calcitonin ≥20 ng/L measured by central laboratory at screening (individuals with elevated calcitonin at initial screening may be re-screened); Laboratory abnormalities at screening; Current or history of clinically significant renal disease (per Investigator's judgment) or eGFR<60mL/min/1.73m2; Screening 12-lead ECG that demonstrates relevant abnormalities that, in the opinion of the Investigator, are clinically significant and indicate an unacceptable risk for the participant's participation in the study (e.g., QTc >450 msec or a QRS interval >120 msec). If QTc exceeds 450 msec, or QRS exceeds 120 msec, the ECG should be repeated two more times and the average of the three QTc or QRS values should be used to determine the participant's eligibility; Diagnosis of T2DM requiring current use of insulin, repaglinide, saxagliptin, and sulfonylureas; Note. Use of Metformin for the purposes of glycemic control is not exclusionary; Current or past diagnosis of pancreatitis; Current or past diagnosis of severe gastroparesis; Pregnant or breast-feeding.
