New hope for tough lymphoma: experimental drug CHO-H01 enters human trials

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Life expectancy of \>12 weeks. * Body mass index of 18 to 32 kg/m2. * Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2. * Phase I: Have histologically (laboratory test) confirmed CD20 + non-Hodgkin's lymphoma according to the World Health Organization's 2016 classification: 1. Low grade lymphoma: follicular lymphoma (Grades 1-3a), marginal zone lymphoma, small lymphocytic lymphoma; 2. Other lymphoma: DLBCL (NOS: to include germinal center B-cell-like \[GCB\] and activated B-cell-like \[ABC\]), follicular lymphoma Grade 3b, mantle cell lymphoma; primary mediastinal large B-cell lymphoma. * Phase IIa: Histologically confirmed CD20 + non-Hodgkin's lymphoma according to the World Health Organization's 2016 classification, only low grade lymphoma: follicular lymphoma (Grades 1-3a), marginal zone lymphoma, small lymphocytic lymphoma. * Have at least one measurable lesion that is at least 1.5 cm in its largest dimension. * Off treatment for 30 days from last anti-CD20 infusion until planned administration of CHO-H01. * If no original sample is available, is willing and able to provide an adequate tumor biopsy sample at Screening. * Have adequate cardiac function: without clinically significant and/or uncontrolled heart disease. * Must be sterile, or have a monogamous partner who is surgically sterile, or at least 2 years postmenopausal, or be committed to use an acceptable form of birth control for the duration of the study (male), and for the duration of the study and for 3 months following the last CHO-H01 administration (female).
