Study BT5528-100 in Patients With Advanced Solid Tumors Associated With EphA2 Expression
Phase I/II Study of the Safety, Pharmacokinetics, and Preliminary Clinical Activity of BT5528 in Patients With Advanced Malignancies Associated With EphA2 Expression
Source: ClinicalTrials.gov · Last updated 16 Oct 2026
Brief summary (registry, in English)
This clinical trial is evaluating a drug called BT5528 alone and in combination with nivolumab in participants with advanced solid tumors historically known for expression of EphA2. The main goals of this study are to: * Find the recommended dose(s) of BT5528 that can be given safely to participants alone and in combination with nivolumab * Learn more about the side effects of BT5528 * Learn about how effective BT5528 is for the treatment of ovarian cancer, urothelial/bladder cancer, lung cancer (NSCLC), triple-negative breast cancer, head and neck cancer (HNSCC), and gastric/upper gastrointestinal cancer. * Learn more about BT5528 therapy alone and in combination with nivolumab.

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.

- Uncontrolled hypertension (systolic BP ≥160 mmHg or diastolic BP ≥100 mmHg that is not responsive to intervention) at screening or prior to initiation of study drug.
- Thromboembolic events and/or bleeding disorders 3 months (e.g., deep vein thrombosis \[DVT\] or pulmonary embolism \[PE\]) prior to first dose

- Patients with a positive hepatitis B surface antigen and/or anti-hepatitis B core antibody. Patients with a negative polymerase chain reaction (PCR) assay are permitted with appropriate antiviral therapy
- Active hepatitis C infection with positive viral load if hepatitis C virus (HCV) antibody positive (if antibody is negative then viral load not applicable). Patients who have been treated for hepatitis C infection can be included if they have documented sustained virologic response of ≥12 weeks.
- History of another malignancy within 3 years before the first dose of BT5528, or any evidence of residual disease from a previously diagnosed malignancy (excluding adequately treated with curative intent basal cell carcinoma, squamous cell of the skin, cervical intraepithelial neoplasia/cervical carcinoma in situ or melanoma in situ or ductal carcinoma in situ of the breast).
- Psychological, familial, sociological, or geographical conditions that do not permit compliance with the protocol and/or follow-up procedures outlined in the protocol.
- Additional Exclusion Criteria (BT5528 in combination with nivolumab):
- Known hypersensitivity to checkpoint inhibitor therapy
- Active systemic infection requiring therapy
- History of autoimmune disease except alopecia, vitiligo, hypothyroidism, or adrenal insufficiency
- History of interstitial lung disease
Lab values
- Any condition, therapy or laboratory abnormality that might confound the results of the study, interfere with the patient's participation, or is not in the best interest of the patient to participate in the opinion of the investigator including but not limited to specific cardiovascular criteria
- History or current evidence of any condition, therapy or laboratory abnormality that might confound the results of the study, interfere with the patient's participation, or is not in the best interest of the patient to participate in the opinion of the Investigator including but not limited to:
- (a) Patients with history of a cerebral vascular event (stroke or transient ischemic attack), unstable angina, myocardial infarction, congestive heart failure or symptoms of New York Heart Association Class III-IV documented within 6 months prior to first dose of BT5528 or: (i) Mean resting corrected QT interval (QTcF) \>470 msec (ii) Any factors that increase the risk of QTc prolongation or risk of arrhythmic events such as heart failure, hypokalemia, congenital long QT syndrome, family history of long QT syndrome or unexplained sudden death under 40 years-of-age, or any concomitant medication known to prolong the QT interval (iii) Any clinically important abnormalities (as assessed by the Investigator) in rhythm, conduction, or morphology of resting electrocardiograms (ECGs), e.g., complete left bundle branch block, third degree heart block
