- Registration Number
- NCT06808815
- Lead Sponsor
- DICE Therapeutics, Inc., a wholly owned subsidiary of Eli Lilly and Company
- Brief Summary
The main purpose of this study is to learn more about the safety and side effects of DC-806 when given by mouth to healthy participants and participants with Chronic Plaque Psoriasis. The study will have three parts. Each participant will enroll in only one part. For each participant, Part 1 will last up to 14 weeks, Part 2 will last up to 12 weeks, Part 3 will last up to 11 weeks including screening and follow-up.

Healthy Subjects (Parts 1 and 2)

After 10 minutes supine rest at the time of screening or prior to dosing on Day 1, any vital signs values outside the following ranges:
- Systolic blood pressure <90 or >150 mmHg, or
- Diastolic blood pressure <50 or >95 mmHg, or
- Pulse <40 or >90 bpm
-
Any clinically significant abnormalities in resting ECG at the time of screening or pre-dose Day 1 including prolonged QTcF (>450 ms for males; >470 ms for females using the mean of triplicate ECG's) and cardiac arrhythmias, as judged by the Investigator or designee.
-
Clinically significant abnormalities in renal function:
• eGFR <60 mL/min

- Bilirubin >1.5 x ULN
- Aminotransferases >1.5 x ULN
- ALP >1.5 x ULN
-
History of latent TB, active tuberculosis, or a positive QuantiFERON® TB Gold result at screening. Patients with an indeterminate QuantiFERON® TB Gold result at screening will be allowed one retest; if not negative on retesting, the subject will be excluded.
-
Females who are pregnant, breast feeding or plan to be pregnant during the study period or 90 days after.
-
Female subjects with a positive serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of human chorionic gonadotropin [hCG]) at screening or within 24 h prior to the first administration of IMP.
-
Positive serum hepatitis B surface antigen (HBsAg), hepatitis C virus antibodies (HCV Ab) or human immunodeficiency virus (HIV) 1 and/or 2 antibodies at screening.
-
Part 2 Only: Presence of active suicidal ideation or positive suicide behaviour using the "Baseline/Screening" version of the Columbia Suicide Severity Rating Scale (C-SSRS) and with either of the following criteria:
- History of a suicide attempt within the 5 years prior to the Screening Visit. Subjects with a history of a suicide attempt more than 5 years ago should be evaluated by a mental healthcare professional (eg, locally licensed psychiatrist, psychologist, or master's level therapist) before enrolling into the study.
- Suicidal ideation in the past month prior to the Screening Visit as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the "Baseline/Screening" version of the C-SSRS.
Participants with Psoriasis (Part 3)
- History or presence of any clinically relevant acute or chronic medical or psychiatric condition other than psoriasis that could interfere with the patient's safety during the clinical study or expose the patient to undue risk as judged by the Investigator or designee.
- A diagnosis of non-plaque psoriasis.
- Plaque psoriasis restricted to the scalp, palms, soles and face.
- Pustular, erythrodermic, inverse, and guttate psoriasis
