A prospective, single-center, open-label, phase 1 study evaluating the pharmacokinetics (PK) of ustekinumab administered via the RaniPill™ capsule ("RT-111").

The RaniPill device is a capsule-like ingestible device, which injects a microneedle containing a micro tablet (payload/drug) into the intestinal wall. This is a single-center, prospective, open-label, phase 1 study.

Healthy Volunteers, 18-65 years of age, of any race, recruited from the general population and assigned to one of the following groups:

• Group 1 (SC Control): Stelara®, 0.5mg via SC injection (N= up to 15)
• Group 2: RT-111-0.50 mg (N= up to 20)
• Group 3: RT-111-0.75 mg (N=up to 20)

Inclusion Criteria:

1. Participant is ambulatory and between 18 to 65 years of age
2. Body mass index between 19- 32 kg/m2
3. RT-111 ONLY: Female volunteers must be non-menstruating at dosing
4. Female volunteers must be non-pregnant or non-lactating during study participation
5. Male volunteers must agree to use acceptable forms of contraception, if necessary, and to not donate sperm during study participation.
6. Have suitable venous access for blood sampling.
7. In good general health confirmed by medical history, physical examination, and absence of clinically important laboratory abnormalities per Investigator's judgment

   5. allergic disease excluding mild asymptomatic seasonal and food allergies.

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

5. Presence or evidence of recent sunburn, scar tissue, tattoo (more than 25% of body area), open sore or branding that, in the opinion of the Investigator, would interfere with interpretation of skin adverse reactions.

6. 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. Evidence of transmural infarction on ECG.
   3. History of sustained hypertension (systolic > 180 mmHg and/or diastolic > 100 mmHg), hypertensive crisis or hypertension encephalopathy.
   4. Clinically significant valvular heart disease or severe arterial thromboembolic events.

7. Have a positive test result for hepatitis B surface antigen (HBsAg), hepatitis C virus, human immunodeficiency virus (HIV) or history of active, latent, or inadequately treated tuberculosis (TB) infection

8. Positive serum pregnancy test for women of childbearing potential at the Screening visit or positive urine pregnancy test with confirmatory serum pregnancy test prior to dosing.

9. Females who are breastfeeding.

10. Have a history of cancer including lymphoma, leukemia, and skin cancer (volunteers with a maximum of 3 surgically resected basal cell carcinoma or squamous cell carcinoma are permitted).

11. Have an illness within 30 days prior to screening, or prior to dosing, that has not resolved and is classed as clinically significant by the Investigator.

12. Any current active infections, including localized infections, or any recent history (within 1 week prior to study drug administration) of active infections (including severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] based on a positive COVID-19 polymerase chain reaction [PCR] nasopharyngeal swab test), cough or fever, or a history of recurrent or chronic infections.

13. Have had major surgery within 30 days prior to screening or will have an operation between screening and the end of study visit, or have any unhealed wound, including wound dehiscence and wound healing complications requiring medical intervention.

14. Have received live vaccines during the past 4 weeks before Screening or have the intention to receive vaccination during the study period or within 13 weeks after dosing.

17. Positive drug or alcohol test results. In the event the urinary drug test is positive, the test may be repeated once (at the discretion of the PI) to confirm eligibility.

19. Abnormal or irregular bowel movements, in the opinion of the Investigator.

20. Any history of non-traumatic hemorrhage (i.e., any hemorrhage requiring medical intervention) or any condition which may increase bleeding risk including clotting disorders, thrombocytopenia (platelet count < 150,000 per μL) or an international normalized ratio higher than 1.5.

21. Impaired liver function as determined by a serum alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST)> 1.5 x upper limit of normal (ULN).
