A Drug Interaction Study of BIIB074 and an Oral Contraceptive Regimen

Study Overview
=================
Brief Summary
-----------------
The primary objective of this study is to evaluate the effect of multiple doses of a uridine diphosphate glucuronosyltransferases (UGT)-inducing oral contraceptive (OC) regimen (ethinyl estradiol and levonorgestrel) on the PK of BIIB074 at steady state; evaluate the effect of multiple doses of BIIB074 on the pharmacokinetics(PK) of an OC regimen (ethinyl estradiol and levonorgestrel) at steady state. The secondary objective of this study is to evaluate the safety and tolerability of BIIB074 when administered alone and when coadministered with a UGT-inducing OC regimen containing ethinyl estradiol and levonorgestrel and to evaluate the effect of a UGT-inducing OC regimen (ethinyl estradiol and levonorgestrel) on the PK of the M13, M14, and M16 metabolites of BIIB074.

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs) | An AE is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. | Approximately 71 days | 
| Number of Participants with Abnormal Change from Baseline in Laboratory Parameters up to Day 33 | Chemistry panel included total protein, albumin, creatinine, blood urea nitrogen, uric acid, bilirubin (total and direct), alkaline phosphatase, ALT, AST, gamma-glutamyl transferase, glucose, calcium, phosphorus, bicarbonate, chloride, sodium, and potassium. | Day 3, 7, 24, 28, 33 | 
| Number of Participants with Abnormal Change from Baseline in Hematology Panel up to Day 33 | Hematology Panel measurements are complete blood count with differential and platelet count, and absolute neutrophil count | Day 3, 7, 24, 28, 33 | 
| Number of Participants with Abnormal Change from Baseline in Urinalysis Panel up to Day 33 | Urinalysis panel included dipstick for occult blood, protein, nitrites, leukocyte esterase, glucose, bilirubin, urobilinogen, ketones, pH, and specific gravity. A microscopic examination will be performed if occult blood, protein, nitrites, or leukocyte esterase is abnormal. | Day 3, 7, 24, 28, 33 | 
| Number of Participants with Abnormal Change from Baseline in Vital Sign Measurements up to Day 33 | Vital signs measurements are temperature, heart rate, systolic and diastolic blood pressure, and respiratory rate | Day 1, 3, 7, 12, 24, 25, 26, 28, 33 |

| Number of Participants with Abnormal Change from Baseline in Physical Examination up to Day 33 | Abnormal physical examinations findings that are noted postbaseline and deemed clinically significant by the Investigator will be reported as AEs and will be included in the AE analyses. | Day -1, 33 | 
| AUC 8 of BIIB074 Metabolites M13, M14, and M16 | AUC8 indicates the actual body exposure to BIIB074 metabolites during 8 hours after administration of a BIIB074 dose and is expressed in mg*h/L. | Day 7, 32 | 
| Cmax for BIIB074 Metabolites M13, M14, and M16 | Cmax is the maximum serum concentration that BIIB074 metabolites M13, 14, and 16 achieves in the body after BIIB074 is administered. | Day 7, 32 | 
| Tmax for BIIB074 Metabolites M13, M14, and M16 | Tmax is the amount of time it takes to reach Cmax of the BIIB074 metabolites13,14, and 16 after BIIB074 has been administered. | Day 7, 32 | 
| Terminal Elimination Half-Life (T 1/2) for BIIB074 Metabolites M13, M14, and M16 | The terminal elimination half-life is the time required to divide the plasma concentration of BIIB074 metabolites M13,14,and 16 by two after reaching pseudo-equilibrium. | Day 7, 32 | 
| Metabolite-to-Parent Ratio in AUC (MRauc) for BIIB074 Metabolites M13, M14, and M16 | The MRauc is the ratio of the BIIB074 metabolites M13,14,and 16 to BIIB074 after administration | Day 7, 32 | 
| Number of Participants with Abnormal Change from Baseline in Columbia Suicide Severity Rating Scale (C-SSRS) Assessments | The C-SSRS captures the occurrence, severity, and frequency of suicide-related thoughts and behaviors during the assessment period. | Day 7, 12, 24, 33, and once between Day 39-42 |
