New Antibody-Drug conjugate enters human trials for advanced cancers
NCT ID NCT06823167
First seen Jun 27, 2026 · Last updated Aug 11, 2026 · Updated 6 times
Summary
This early-stage trial tests IM-1021, an antibody-drug conjugate designed to deliver a cancer-killing drug directly to tumor cells. It enrolls 117 adults with advanced solid tumors or B-cell lymphomas that have not responded to standard treatments. The main goals are to check safety and find the right dose for future studies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IM-1021 (an antibody-drug conjugate)
- What this could lead to
- If successful, this could point toward a new treatment option for people with advanced cancers that have not responded to other therapies.
- What could go wrong
- This is an early Phase 1 trial with only 117 participants, so the main goal is safety and dosing—not yet proving effectiveness. Side effects are unknown and could be serious.

Inclusion Criteria: 1. Informed consent signed by the participant prior to conducting study-specific procedures 2. ≥18 years of age 3. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2 4. Histological or cytological diagnosis of: Part A: advanced B-cell lymphomas or solid tumors, of the following subtypes: B-cell Lymphomas: * Mantle cell lymphoma (MCL) * Diffuse large B-cell lymphoma (DLBCL) (including Richter's transformation) * Follicular lymphoma * Small lymphocytic lymphoma (SLL) * Marginal zone lymphoma Solid Tumors: * Pancreatic cancer * Non-squamous non-small cell lung cancer (NSCLC) * Malignant mesothelioma * Epithelial ovarian cancer. Participants with fallopian tube and/or peritoneal malignancies are also eligible. * Triple-negative breast cancer. * Liposarcoma Other, unlisted histologies, if approved by the Sponsor Medical Monitor Part B Cohorts B1, B2, and B3: Histological or cytological diagnosis of the cohort-specific disease indication. Indications may include those listed in Inclusion Criterion 4.a 5. Participants must have adequate organ function. 6. Participants must have a negative pregnancy test, be willing to practice highly effective methods of birth control, use condoms, and refrain from oocyte/sperm donation, as applicable, as detailed in the protocol. 7. Participants must have relapsed or refractory disease and have received all approved and available therapeutic options. 8. Participants must have measurable disease as per the relevant response assessment framework: Lugano Classification for lymphoma (except SLL), per iwCLL criteria for SLL , and per RECIST v.1.1 for solid tumors. Exclusion Criteria: 1. Previously treated with an ADC with a topoisomerase-1 inhibitor payload, except: Participants with triple negative breast cancer may have received up to one prior ADC with a topoisomerase-1 inhibitor payload. 2. Previously received a ROR1-targeted therapy (eg, ADC, cell therapy, or monoclonal antibody). 3. History of an anaphylactic reaction to irinotecan or ≥ grade 3 GI toxicity to prior irinotecan. 4. Life expectancy \< 12 weeks. 5. Prior solid organ transplant. 6. Participants with symptomatic ascites or pleural effusion. Participants who are clinically stable for at least 2 weeks following treatment for these conditions (including therapeutic thoraco- or paracentesis or catheter) are eligible. 7. For participants with known active central nervous system (CNS) disease 1. For participants with solid tumors: Participant has a known active CNS primary tumor or metastases and/or carcinomatous meningitis. Participants with previously treated brain metastases may participate provided they are clinically stable for at least 4 weeks prior to study entry, have no radiological evidence of new or enlarging brain metastases, and are off steroids or on a stable dose up to an equivalent of prednisone 10 mg/day for at least 15 days prior to first dose of study medication. Participants who have symptoms consistent with CNS metastasis must have a negative magnetic resonance imaging (MRI) or other clinically appropriate imaging study if the participant is not able to undergo contrast-enhanced MRI and approved by the Sponsor Medical Monitor during the screening period. 2. For participants with lymphoma: Participant has active cerebral/meningeal disease related to the underlying malignancy. Participants with a history of cerebral/meningeal disease related to the underlying malignancy are allowed if prior CNS disease has been effectively treated and without progression for at least 3 months. 8. Participant has a known history of malignant primary brain tumor, or another primary solid or hematologic malignancy (other than that under study), unless the participant has undergone potentially curative therapy with no evidence of that disease for at least 2 years. Exception: The time requirement does not apply to participants who underwent successful definitive resection of certain cancers. 9. Participant has certain other significant medical conditions including cardiac, pulmonary, and infectious disease as detailed in the protocol. 10. Participant is pregnant, breastfeeding, or expecting to conceive within the projected duration of the study.
