Breast Cancer Clinical Trial

Study BT5528-100 in Patients With Advanced Solid Tumors Associated With EphA2 Expression

Summary

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 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.

View Full Description

Full Description

BT5528 consists of a bicyclic peptide (Bicycle®) which binds to EphA2, and is covalently attached to a spacer and a protease cleavable peptide linker attached to MMAE.

The Phase I/II multi-center, open-label trial will evaluate BT5528 administered once-weekly as a single agent and in combination with nivolumab. The Phase I portion is a dose escalation primarily designed to assess the safety and tolerability of BT5528 and to determine a recommended Phase II dose (RP2D). Following selection of a recommended Phase II dose (RP2D), a dose expansion portion will be initiated with the primary objective of evaluating the clinical activity of BT5528.

Eligibility Criteria

General Inclusion:

Written informed consent, according to local guidelines, signed and dated by the patient or by a legal guardian prior to the performance of any study-specific procedures, sampling or analyses
At least 18 years-of-age at the time of signature of the informed consent form
Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1
Measurable disease per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1
Acceptable renal, hepatic, hematologic and coagulation functions
Negative pregnancy test for women of childbearing potential
Male participants with female partners of childbearing potential and female participants of childbearing potential are required to follow highly effective contraception
All patients must have tumor tissue (fresh or archived) available for analysis of EphA2 tumor expression and other biomarkers. In the absence of available tumor tissue, patients must be willing to undergo a biopsy to provide fresh tumor samples
Life expectancy ≥12 weeks after the start of BT5528 treatment according to the Investigator's judgment.
Must be willing and able to comply with the protocol and study procedures.

Additional inclusion criteria for Phase I (dose escalation phase, with BT5528 alone or in combination with nivolumab):

Metastatic recurrent histologically confirmed malignant solid tumors historically known for high EphA2 tumor expression. Confirmation of EphA2 expression prior to enrollment is not required for participants with ovarian cancer and specific other individual tumor types.
Exhausted all appropriate treatment options per local guidelines

Additional inclusion criteria for Phase II (dose expansion phase, with BT5528 alone):

Participants with metastatic recurrent disease histologically confirmed to be non-small cell lung cancer, ovarian cancer, triple-negative breast cancer (TNBC), gastric/upper gastrointestinal (GI) cancer, head and neck (H&N) cancer, urothelial cancer are eligible and must have failed or are ineligible for all appropriate treatment options per local guidelines and must have evidence of radiographic progression on the most recent line of therapy
Patients with urothelial cancer who have previously received treatment with enfortumab vedotin (EV) are eligible to the study. Patients who received EV and showed disease progression within 6 months of treatment start are planned for less than 50% of total patients enrolled in the cohort

Exclusion criteria (all participants):

Chemotherapy treatments within 14 days prior to first dose of study treatment, other anticancer treatments, treatment within 28 days or 5 half-lives, whichever is the shorter
Experimental treatments within 4 weeks of first dose of BT5528
Prior toxicities must have resolved to Grade 1 per Common Terminology Criteria for Adverse Events (CTCAE) v 5.0 (except alopecia which can be Grade 2)
Current treatment with strong inhibitors or inducers of CYP3A4 or strong inhibitors of P-gp
Known sensitivity to any of the ingredients of the investigational product or monomethyl auristatin E (MMAE)
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
Major surgery (excluding placement of vascular access) within 4 weeks of first dose of BT5528 study treatment and must have recovered adequately prior to starting study therapy
Receipt of live vaccine within 30 days of study treatment
Untreated CNS metastases or leptomeningeal disease
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.

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

Known human immunodeficiency virus (HIV) or acquired immune deficiency syndrome (AIDS). Note: Well controlled HIV will be allowed if the patient meets all the following criteria at inclusion:

CD4+ T-cell (CD4+) counts ≥350 cells/uL;
HIV viral load <400 copiesmL
Without a history of opportunistic infection within the last 12 months.
On established antiretroviral therapy (ART) for at least 4 weeks. Use of anti-retroviral therapy is permitted, but should be discussed with the Medical Monitor on a case-by-case basis.
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.
Thromboembolic events and/or bleeding disorders 3 months (e.g., deep vein thrombosis [DVT] or pulmonary embolism [PE]) prior to first dose
Prior history of pneumonitis with presence of residual symptoms
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).
Systemic anti-infective treatment or fever within the last 14 days prior to first dose of BT5528 study treatment
