Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Cohort 1 Gray-Zone Lymphoma (GZL) | Cohort 1: B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma (i.e., Gray-zone lymphoma or GZL)~Participants will be treated with pembrolizumab 200 mg (flat dose) intravenous (IV) every 3 weeks provided they have clinical benefit and no unacceptable toxicity; participants who achieve a complete response (CR) will have the option to stop after 1 year of therapy. | 0 | 2 | EG000 |
| Group 2 | Cohort 2 Extra-nodal Diffuse Large B-cell Lymphoma (DLBCL) | Cohort 2: Extra-nodal diffuse large B-cell lymphoma involving one or more of the specified extra-nodal sites (i.e., extra-nodal DLBCL)~Participants will be treated with pembrolizumab 200 mg (flat dose) intravenous (IV) every 3 weeks provided they have clinical benefit and no unacceptable toxicity; participants who achieve a complete response (CR) will have the option to stop after 1 year of therapy. | 5 | 9 | EG001 |
