Can a smart drug deliver a One-Two punch to advanced cancers?
NCT ID NCT05279300
First seen Aug 21, 2026 · Last updated Sep 02, 2026 · Updated 2 times
Summary
This trial tests an experimental drug called CS5001, designed to seek out and destroy cancer cells that carry a specific marker (ROR1). It is being studied in people with advanced solid tumors or lymphomas that have progressed after standard treatments. The study will first find the safest dose, then test how well it works alone or combined with other cancer therapies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CS5001, an antibody-drug conjugate that targets a protein called ROR1 on cancer cells, given alone or with standard cancer drugs
- What this could lead to
- If successful, this could lead to a new treatment option for advanced solid tumors and lymphomas that have not responded to prior therapies.
- What could go wrong
- This is an early-phase trial, so the drug may not be effective or may cause significant side effects. The results are preliminary and need confirmation in larger studies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * For solid tumor patients of dose escalation, they must have pathologically confirmed, unresectable advanced solid tumor with disease progression on or after at least 1 line of prior systemic therapy. * For Lymphoma patients of dose escalation, they must have pathologically confirmed Hodgkin and non-Hodgkin B-cell lymphoma as defined per 2016 World Health Organization(WHO) classification, with disease progression on or after at least 2 lines of prior systemic therapy. * For mono-therapy cohorts, eligible patients must have pathologically confirmed relapsed/refractory (R/R) lymphomas or advanced solid tumors, and have demonstrated failure with previous line(s) of standard-of-care treatment. Patients in the solid tumor cohort must exhibit ROR1-positive expression in their baseline tumor tissues. For combination therapy cohorts, DLBCL patients must either be treatment-naïve or have experienced failure with at least one prior line of standard-of-care therapy to qualify for treatment with CS5001 in combination with first-line or subsequent standard-of-care therapies for DLBCL. Solid tumor patients must have pathologically confirmed disease, be naïve to PD-1/PD-L1 inhibitors, and have at least failed first-line therapy or standard-of-care treatment. * For dose escalation, with at least one evaluable lesion as defined per Response Evaluation Criteria in Solid Tumours(RECIST) v1.1 solid tumor or per 2014 Lugano Classification Criteria for lymphoma, respectively. For dose expansion, with at least one measurable lesion as defined per RECIST v1.1 solid tumor or per 2014 Lugano Classification Criteria for lymphoma, respectively. * Life expectancy \> 3 months. * Eastern Cooperative Oncology Group(ECOG) performance status 0-2. * Have adequate organ function. Exclusion Criteria: * Has disease that is suitable for local treatment administered with curative intent. For lymphoma, candidacy for hematopoietic stem cell transplantation based on the Investigator's judgment. * Has a history of a second malignancy active within the previous 3 years except for locally curable cancers that have been apparently cured. * For dose expansion: Participation in other studies involving therapies targeting ROR1 prior to study entry and/or during study participation. * Has known central nervous system (CNS) lymphoma or solid tumor CNS metastasis that is either symptomatic, untreated, or requires therapy. * Has other acute or chronic medical or psychiatric conditions. * Has a diagnosis of immunodeficiency, or has an active autoimmune disease or other conditions that require systemic steroid therapy. * Has peripheral edema, pericardial effusion, or ascites indicated for medical intervention or limiting activity of daily life. Or with a known history of peripheral vasculopathies. * Patients with any active infections requiring systemic therapy within 2 weeks prior to the administration of the first dose of the study drug. * Patients known to be human immunodeficiency virus (HIV)-positive or have acquired immune deficiency syndrome (AIDS). * Significant cardiovascular disease within 6 months prior to the first dose of the study drug. * Significant screening electrocardiogram (ECG) abnormalities. * Has received major surgery, chemotherapy, definitive radiotherapy, target therapy, immunotherapy, or other anti-cancer therapy within 21 days prior to the administration of the first dose of the study drug. * Administration of a live vaccine within 28 days prior to the administration of the first dose of the study drug. * Has active graft versus host disease. * With known active alcohol or drug abuse. * Women who are pregnant or breastfeeding.
