Experimental 'T cell Engager' takes on Hard-to-Treat cancers
NCT ID NCT05359445
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial is testing a new drug called IMA401, which helps the body's immune T cells attack cancer cells that have certain markers (MAGE-A4 or MAGE-A8). The study includes about 95 adults with advanced solid tumors that have come back or not responded to other treatments. Some participants will get IMA401 alone, and others will get it combined with the immunotherapy Keytruda, to see if it is safe and shows signs of shrinking tumors.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IMA401 (a bispecific T cell engaging molecule) and pembrolizumab (Keytruda, a checkpoint inhibitor)
- What this could lead to
- If this works, it could point toward a new treatment option for certain hard-to-treat solid tumors that express MAGE-A4 or MAGE-A8.
- What could go wrong
- This is a very early (Phase 1) trial with only 95 participants, so safety and dosing are still being figured out. Many early-stage cancer drugs do not end up working in larger studies.

Inclusion Criteria: * Patients must have voluntarily signed a written ICF, be able to understand and comply with clinical trial procedures * Patients ≥ 18 years old * Patients must have pathologically confirmed and documented advanced and/or metastatic NSCLC or HNSCC, other solid tumor may be considered * Confirmed HLA status and IMA401 tumor target MAGE-A4 and/or MAGE-A8 expression * Life expectancy \> 2 months * ECOG Performance Status of 0 to 1 * Measurable disease according to RECIST 1.1 * Adequate baseline hematologic, renal and hepatic function; acceptable coagulation status * Patients must have recurrent and/or refractory solid tumors and must have received or not be eligible for all available indicated standard of care treatments * The patient must have recovered from any side effects of prior therapy to Grade 1 or lower (except for non-clinically significant toxicities; e.g., alopecia, vitiligo) prior to treatment start. As determined by the investigator, the patient may still be eligible if the patient has not fully recovered from Grade ≥ 2 toxicities, in case if these toxicities are not anticipated to further improve (e.g., chronic peripheral neuropathy) and such toxicities are not anticipated to worsen with the IMA401 therapy Exclusion Criteria: * Other active malignancies that require treatment or that might interfere with the trial endpoints (ongoing adjuvant anti-hormonal treatment is allowed) * History of hypersensitivity to components of IMA401, CPI treatment or rescue medications, contraindication for pembrolizumab * Patients with prior allogeneic stem cell transplantation or organ transplantation * Patients with autoimmune diseases needing disease-directed treatment * Any serious or uncontrolled health condition, which, in the opinion of the Investigator, would place the subject at undue risk from the study, impair the ability of the subject to receive protocol specified therapy, or interfere with the interpretation of study results * Positive for HIV or with active hepatitis B or C infection. * Patients with active infection * Systemic corticosteroids (≥ 10 mg/day prednisone or equivalent) received 2 weeks prior to starting trial treatment * Patients with active central nervous system metastases and leptomeningeal metastases
