Brentuximab vedotin will be administered every 3 weeks at a dose of 1.8 mg/kg.

Brentuximab vedotin will be administered every 3 weeks at a dose of 1.8 mg/kg beginning on Cycle 1, Day 1; daily rifampicin (600 mg PO) will be administered during Cycles 0 through 3 only, beginning on Cycle 0, Day 1 (7 days before the Cycle 1, Day 1 dose of brentuximab vedotin) and continuing through Cycle 3, Day 21.

Medical Monitor

This is an open-label trial to estimate the concentrations of brentuximab vedotin in relapsed/refractory Hodgkin lymphoma (HL) or relapsed/refractory systemic anaplastic large cell lymphoma (sALCL) participants treated with either brentuximab vedotin or brentuximab vedotin + rifampicin.

A Phase 1 Study in Patients With Relapsed or Refractory Hodgkin Lymphoma or Systemic Anaplastic Large Cell Lymphoma

A Phase 1 Study to Estimate MMAE Metabolites in Human Plasma and Urine in Patients With Relapsed or Refractory Classical Hodgkin Lymphoma or Relapsed or Refractory Systemic Anaplastic Large Cell Lymphoma Receiving Brentuximab Vedotin

Metabolites of MMAE includes C4, C5, C7, C8 and C13. The lower limit of Quantification (LLQ) for all the observations was 0.01 nanogram/milliliter (ng/mL).

Metabolites of MMAE includes C4, C5, C7, C8 and C13. The LLQ for all the observations was 0.01 ng/mL.

Metabolites of MMAE includes C4, C5, C7, C8 and C13. Amount of MMAE and its metabolites in urine were determined by multiplying the volume of urine obtained and the concentration of MMAE and its metabolites present in it, respectively. The LLQ for determining the concentration was 0.01 ng/mL.

The LLQ for all the observations was 12.5 ng/mL.

An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event. AEs included both SAE and non-SAE.

Participants with positive ATA at both Cycle 1 and 3, negative ATA at both Cycle 1 and 3, and transient positive (positive at one time point, but negative at the other) ATA for brentuximab vedotin were reported.

The number of participants with any markedly abnormal standard safety laboratory values collected throughout study.

Vital signs included body temperature, body weight, blood pressure and heart rate.

Serious and non-serious AEs were collected from first dose through 30 days after the last dose (Cycle 16). Beginning on Cycle 4 Day 1, only AEs with Grade 3 were recorded. Exceptions: New onset AEs of Grade 1-2 were recorded if they met criteria for SAEs or resulted in dose modification; PN events will be recorded regardless of severity grade.

Brentuximab vedotin 1.8 mg/kg, injection, intravenously, every 3 weeks on Day 1 of each 21-day treatment cycle up to a maximum of 16 brentuximab vedotin doses.

ECOG performance status is used to assess how the disease affects the daily living abilities of the participant. It ranges on the scale from 0-5 (0= normal activity; 1= symptoms but ambulatory; 2= in bed for less than (\<) 50 percent (%) of the time; 3= in bed for greater than (\>) 50% of the time; 4= 100% bedridden; 5= dead.

Ann Arbor staging is staging system for lymphomas. The stage is determined by location of tumor. Stage I (located in a single region, usually 1 lymph node and surrounding area), Stage II (located in 2 separate regions, an affected lymph node or organ and a second affected area, and both affected areas are confined to 1 side of diaphragm), Stage III (spread to both sides of diaphragm, including organ/area near lymph nodes/spleen), Stage IV (diffuse or disseminated involvement of 1 or more extra lymphatic organs, including any involvement of liver, bone marrow or nodular involvement of lungs).

Ann Arbor Stage

Safety population included all participants who received at least 1 dose of study drug.
