Clinical Trial Summary

This first-in-human (FIH) trial aims to establish a safe dose of BNT411 as a monotherapy and in combination with atezolizumab, carboplatin and etoposide. BNT411 is a toll-like receptor 7 (TLR7) agonist which is expected to mount broad innate and adaptive immune reactions, especially in combination with cytotoxic therapies and immune checkpoint inhibitors.


Description:

The first part (Part 1A) of this trial is a FIH, open-label, dose-escalation trial studying BNT411 monotherapy in patients with different types of malignant solid tumors in order to determine the safety profile of BNT411. The second part (Part 1B) aims to determine further the safety profile of BNT411 in combination with atezolizumab, carboplatin and etoposide in patients with chemotherapy-naïve ES-SCLC. The third part (Part 2) is the expansion phase to explore BNT411 further as a monotherapy or in combination with atezolizumab, carboplatin and etoposide in select tumor indications. Different treatment schedules and other indications may also be explored in Part 2.

Eligibility Inclusion Criteria: For Part 1A: - Histologically confirmed solid tumor (cytology is allowed for non-small cell lung cancer [NSCLC], small cell lung cancer [SCLC] and pancreatic cancer) that is metastatic or unresectable and for which there is no available standard therapy likely to confer clinical benefit, or patients who are not candidates for such available therapy. For Part 1B: - Histologically or cytologically confirmed ES-SCLC (per the Veterans Administration Lung Study Group [VALG] staging system) who received no prior chemotherapy for extensive stage disease. - Those treated with prior chemo/radiotherapy with curative intent for limited-stage small cell lung cancer (LS-SCLC) should be treatment-free for at least 6 months since last chemo/radiotherapy. - No interstitial lung disease or active, non-infectious pneumonitis. For Both Part 1A and Part 1B: - Male and female =18 years of age. - Must sign an informed consent form (ICF) indicating that he or she understands the purpose of and procedures required for the trial and are willing to participate in the trial prior to any trial-related assessments or procedures. - Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1. - Measurable disease according to RECIST 1.1. - Albumin level at screening =30 g/L. - Adequate coagulation function at screening as determined by: 1.
