General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study was to assess the antitumor activity of single-agent MOR00208 in adult patients with relapsed or refractory NHL who have received at least 1 prior therapy containing rituximab as one of the treatments.
|
||
Protection of trial subjects |
This trial was designed, conducted and reported in accordance with the International Conference on Harmonisation (ICH) Guidelines for Good Clinical Practice (GCP), applicable local regulations (including European Directive 2001/20/EC), and following the ethical principles laid down in the Declaration of Helsinki. Specific ICH adopted and other relevant international guidelines and recommendations were taken into account as far as meaningfully possible. Safety monitoring for all patients enrolled in the study included laboratory safety assessments (haematology, blood chemistry, urinalysis, coagulation, and anti-MOR00208 antibodies) and clinical evaluations (physical examinations, vital signs, 12-lead ECG) as detailed in the Schedule of Assessments.

Recruitment
|
|||||||||||||||||||||||||||
Recruitment details |
This was a Phase IIa open-label, multicenter safety and efficacy study of MOR00208, that was planned to enroll approximately 40 to 120 adult patients with refractory or relapsed NHL who have received at least 1 prior therapy containing rituximab. | ||||||||||||||||||||||||||
Pre-assignment
|
|||||||||||||||||||||||||||
Screening details |
Patients were male or female ≥ 18 years of age, with a histologically confirmed diagnosis of FL, other indolent NHL (e.g., MZL/MALT), DLBCL, or MCL. Patients must have had progression of their NHL after at least 1 prior rituximab-containing regimen, and had at least 1 site of measurable disease on an MRI or CT scan. | ||||||||||||||||||||||||||
