An Early Phase Study of RT-114

Phase 1

Not yet recruiting

• Conditions: Obesity
• Interventions: Drug: PG-102; Combination Product: RT-114 is the RaniPill capsule with PG-102 for the treatment of obesity; Other: Placebo

• Registration Number: NCT06891287
• Lead Sponsor: RANI Therapeutics

Brief Summary

The goal of this Phase 1 study is to evaluate the safety and tolerability of RT-114 in healthy volunteers. The main objectives are:

Primary: To evaluate safety and tolerability of RT-114 when administered as single and multiple doses by assessing treatment emergent adverse events (TEAEs) in healthy volunteers

Secondary:

* To determine the pharmacokinetics of RT-114 administered as single and multiple doses

* To determine the pharmacodynamic effects of RT-114 administered as multiple doses

In the single dose portion of the study participants will either receive the drug via a subcutaneous injection or an oral pill (RT-114). In the repeat dose portion of the study participants will randomized to either RT-114 or a placebo.

8. Have a history of prolonged immunosuppressant therapy or photochemotherapy treatment.

9. Have a history of and/or current cardiac disease defined as one of the following:

   1. History of congestive heart failure; angina pectoris requiring anti-anginal medication.
   2. History of transmural infarction on ECG, if ECG results are available.
   3. History of sustained hypertension (systolic > 180 mmHg and/or diastolic > 100 mmHg), hypertensive crisis or hypertension encephalopathy.
