A Study to Evaluate the Effect of Multiple Doses of CC-90001 on the Pharmacokinetics of Omeprazole, Midazolam, Warfarin, Rosuvastatin, Metformin, Digoxin, and Nintedanib in Healthy Adult Subjects

This is a four-part study to evaluate the effect of multiple doses of CC-90001 on the PK, safety, and tolerability of single doses of omeprazole, midazolam, warfarin, rosuvastatin, metformin, digoxin, and nintedanib in healthy subjects. Each study part is a nonrandomized, fixed-sequence, open-label, two-period study. The study parts can be run in any order and can be, but do not have to be, run in parallel. Subjects may participate in one part only. For each part, each subject will participate as follows:

* Screening (Days -21 through -2)
* Baseline phase for each study period (Periods 1 and 2)
* Treatment phase for each study period (Periods 1 and 2)
* Follow-up telephone call

This study will consist of 4 parts. Each part has two periods. The parts may be conducted in any order. Subjects may participate in 1 part only.

Each subject will participate in a screening phase, a baseline phase in each study period, a treatment phase in each study period and a follow-up telephone call. Subjects will be screened for eligibility. Eligible subjects will return to the study center on Day -1 of Period 1 and will remain at the study center until the last day of Period 2.

In Part 1, Single doses of omeprazole, midazolam, warfarin, and vitamin K will be administered under fasted conditions on Period 1, Day 1. During Period 2, subjects will receive once daily (QD) doses of CC-90001 from Days 1 through 18. On the day of dosing with probe drugs, CC-90001 will be dosed following an overnight fast. On all other days, CC-90001 can be dosed without regard to food. On Period 2, Day 14, subjects will also be administered single doses of omeprazole, midazolam, warfarin, and vitamin K under fasted conditions.

In Part 2, A single dose of rosuvastatin will be administered under fasted conditions on Period 1, Day 1. There will be a washout period of 5 to 10 days between Period 1, Day 1 and Period 2, Day 1. During Period 2, subjects will receive QD doses of CC-90001 from Days 1 through 6. On the day of dosing with probe drug, CC-90001 will be dosed following an overnight fast. On all other days, CC 90001 can be dosed without regard to food. On Period 2, Day 5, subjects will also be administered a single dose of rosuvastatin under fasted conditions.

In Part 3, single doses of metformin and digoxin will be administered under fasted conditions on Period 1, Day 1.

There will be a washout period of 5 to 10 days between Period 1, Day 1 and Period 2, Day 1. During Period 2, subjects will receive QD doses of CC-90001 from Days 1 through 6. On the day of dosing with probe drugs, CC-90001 will be dosed following an overnight fast. On all other days, CC 90001 can be dosed without regard to food. On Period 2, Day 5, subjects will also be administered single doses of metformin and digoxin under fasted conditions.

In Part 4, a single dose of nintedanib will be administered 30 minutes after the start of a standard breakfast on Period 1, Day 1. There will be a washout period of 5 to 10 days between Period 1, Day 1 and Period 2, Day 1. During Period 2, subjects will receive QD doses of CC-90001 from Days 1 through 14. On the day of dosing with probe drug, CC 90001 will be dosed 30 minutes after the start of a standard breakfast. On all other days, CC 90001 can be dosed without regard to food. On Period 2, Day 14, subjects will also be administered a single dose of nintedanib 30 minutes after the start of a standard breakfast.

Eligibility Criteria:
Inclusion Criteria:

Subjects must satisfy all of the following criteria to be eligible for enrollment into the study:

* Must understand and voluntarily sign a written informed consent form (ICF) prior to any study-related assessments/procedures being performed.
* Must be able to communicate with the investigator and to understand and adhere to the study visit schedule and other protocol requirements.
* Must be a male or female of any race, aged ≥ 18 to ≤ 64 years of age (inclusive) at the time of signing the ICF.
* Females of childbearing potential (FCBP) must agree to ongoing pregnancy testing during the course of the study and at the end of the study. This applies even if the subject practices true abstinence from heterosexual contact. Note: Females of childbearing potential are not permitted in Part 4.
* Part 4 only: Female subjects must be of nonchildbearing potential as confirmed by medical history. Females of childbearing potential are permitted in Parts 1, 2, and 3.
* Male subjects must practice true abstinence from heterosexual contact (which must be reviewed on a monthly basis, as applicable) or agree to use a male condom (latex or nonlatex condom not made out of natural \[animal\] membrane \[eg, polyurethane\]) during sexual contact with a pregnant female or a FCBP while participating in the study and for at least 28 days after the last dose of study drug, even if he has undergone a successful vasectomy as confirmed by medical history.
* Must have a body mass index ≥ 18 and ≤ 33 kg/m2 (inclusive) at the time of signing the ICF.
* Must be healthy as determined by the investigator on the basis of medical history, clinical laboratory test results, vital signs, and 12-lead ECG at screening and Period 1 check-in, as applicable:
* Must be afebrile (febrile is defined as ≥ 38°C or 100.3°F).
* Systolic blood pressure must be in the range of 90 to 140 mmHg, diastolic blood pressure must be in the range of 55 to 90 mmHg, and pulse rate must be in the range of 50 to 110 bpm. Repeat vital signs may be measured at investigator discretion.
* Corrected QT interval using Fridericia's formula (QTcF) value must be ≤ 430 msec for male subjects and ≤ 450 msec for female subjects. An ECG may be repeated up to two times, and the average of the QTcF values will be used to determine subject eligibility.

Exclusion Criteria:

The presence of any of the following will exclude a subject from enrollment into the study:
