Patient-reported and Clinical Outcomes in Adults With Relapsed or Refractory Hodgkin's Lymphoma Receiving Brentuximab Vedotin

Study Overview
=================
Brief Summary
-----------------
The goal of this is study is focusing on assessment of patient-reported outcomes in terms of quality of life (QoL) and symptom profile as well on evaluation of clinical efficacy and safety of BV in patients with refractory/resistant HL in a real-world setting.

Detailed Description
-----------------
Information on QoL in patients with refractory/relapsed HL treated with BV is quite limited till now. Moreover, PRO data in patients treated for refractory/relapsed HL with BV, including long-term effects of BV on patient's QoL in a real-world setting are lacking. The goal of this is study is focusing on assessment of patient-reported outcomes in terms of QoL and symptom profileas well on evaluation of clinical efficacy and safety of BV in patients with refractory/resistant HL in a real-world setting. For PROs assessment QoL and symptom data will be received from patients' reports before and at 3, 6, 9, 12 months after BV treatment start and in 3 months at follow-up (15 months after base-line). The maximum duration of PRO monitoring - 15 months. To evaluate PROs the followings tools will be used: RAND SF-36 for quality of life assessment, Edmonton Symptom Assessment System (ESAS-R) for symptom assessment and Patient Global Impression of Change (PGIC) for assessment of a patient's belief about the effect of treatment. For evaluation of response rates, duration of response, PFS and for analysis of AEs/SAEs during BV treatment the clinical data will be collected from health records at base-line, at 3, 6, 9, 12 months after BV treatment start and at 15 months of follow-up or till the last dose of BV. No randomization and stratification will be applied. The analysis of primary (PROs assessment) and secondary outcomes (clinical outcomes) will be provided in the total patient population (n=70) and in two subgroups. The subgroups of interest will be: patients with relapsed or refractory HL who are not candidates for ASCT with prescribed treatment with BV as ≥2nd line therapy, and patients with relapse after ASCT with prescribed treatment with BV.

Arms and Interventions

| Intervention/Treatment |
| --- |
|Drug: Brentuximab Vedotin|Brentuximab vedotin (BV) will be prescribed to patients in accordance with indication for treatment as second or subsequent line therapy after failure of at least one type of first-line therapy for patients with relapsed or refractory HL who are not candidates for ASCT, or for patients with relapse after ASCT within routine hematological practice. Dose, preparation, administration etc - as in Instruction for use (Prescribing information).|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in QoL and symptom severity while treatment with BV | The change in QoL will be assessed as the difference in QoL scales of RAND SF-36 as compared to their baseline and the difference in proportion of patients with significant negative impact on QoL. The change in symptom severity will be assessed as the difference in the severity of each ESAS-R scale and the symptom distress score as compared with their baseline value. The proportion of patients with ≥1 point improvement on ESAS-R scale will be analyzed as well. | At 3, 6, 9 and 12 months of BV treatment and at 15 months after treatment start | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall response rate | Tumor response will be assessed and derived using the RESIST criteria v. 1.0. | At 3, 6, 9 and 12 months of BV treatment at treatment discontinuation | 
| Progression-free survival (PFS) | PFS will be estimated from initiation of treatment with BV till the disease progression or death from any cause. | 15 months | 
| Adverse events (AEs)/serious AEs | The analysis of safety of BV will include reporting adverse events (AEs)/serious AEs (SAEs). For adverse events assessment the NCI CTCAE v. 4.0 will be used. The incidence and severity of any AEs/SAEs will be evaluated within the study | At 3, 6, 9 and 12 months of BV treatment |
