Brief Summary:

This is an open-label, multicenter Phase I/IIa dose escalation, safety, pharmacokinetic (PK) and pharmacodynamic (PD) trial of BNT151 with expansion cohorts in various solid tumor indications. The trial consists of Part 1, Part 2A and Part 2B with adaptive design elements:

The monotherapy dose escalation (Part 1) of this clinical trial will enroll patients with various solid tumors that are metastatic (Stage IV) or unresectable for whom there is no available standard therapy likely to confer clinical benefit, or patients who are not candidates for such available therapy. During combination dose escalation (Part 2A), patients of different specific solid tumors (one cohort per indication) will be enrolled and treated with a combination of BNT151 and the respective standard of care (SoC) treatment.

Part 2B is the expansion phase where a predefined number of patients in each indication cohort will be treated with the confirmed recommended phase II dose (RP2D) of BNT151 in combination with respective SoC.

Official Title: Phase I/IIa, First-in-human, Open-label, Dose Escalation Trial With Expansion Cohorts to Evaluate Safety, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of BNT151 as a Monotherapy and in Combination With Other Anti-cancer Agents in Patients With Solid Tumors

Estimated Primary Completion Date : September 2022
Estimated Study Completion Date : January 2025

Arm Intervention/treatment
Experimental: Part 1: BNT151
Monotherapy dose escalation in patients with advanced solid malignancies until the maximum tolerated dose (MTD) and/or RP2D
Biological: BNT151

Primary Outcome Measures :
  1. Occurrence of dose limiting toxicities (DLTs) within a patient during the DLT evaluation period. [ Time Frame: up to 21 days ]
  2. Occurrence of treatment emergent adverse event (TEAE) within a patient including Grade ≥3, serious, fatal TEAE by relationship. [ Time Frame: through study completion, an average of 6 months ]
    The intensity of an TEAE will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v.5.0).

  3. Occurrence of dose reduction and discontinuation of investigational medicinal product (IMP) within a patient due to TEAE. [ Time Frame: through treatment completion, an average of 4 months ]

Secondary Outcome Measures :
  1. Overall response rate (ORR) is defined as the proportion of patients in whom a complete response (CR) or partial response (PR) (per Response Evaluation Criteria in Solid Tumors [RECIST 1.1]) is observed as best overall response. [ Time Frame: through study completion, an average of 6 months ]
  2. Disease control rate (DCR) is defined as the proportion of patients in whom a CR or PR or stable disease (SD) (per RECIST 1.1, SD assessed at least 6 weeks after first dose) is observed as best overall response. [ Time Frame: through study completion, an average of 6 months ]
  3. Duration of response (DOR) is defined as the time from first overall response (CR or PR per RECIST 1.1) to first occurrence of objective tumor progression (Progressive disease (PD) per RECIST 1.1) or death from any cause, whichever occurs first. [ Time Frame: through study completion, an average of 6 months ]
  4. Time to progression (TPP) is defined as the time from first dose of IMP to objective tumor progression (PD per RECIST 1.1). [ Time Frame: through study completion, an average of 6 months ]

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Histological documentation of the original primary tumor via a pathology report.
  • Measurable disease per RECIST1.1.

For Part 1:

  • Histologically confirmed solid tumor that is metastatic (Stage IV) or unresectable and for whom there is no available standard therapy likely to confer clinical benefit, or patient who is not a candidate for such available therapy. If there is no contraindication, patients should have exhausted all SoC therapies before entering the trial.

For all Parts:

  • ≥18 years of age.
  • Must sign an informed consent form (ICF) indicating that he or she understands the purpose 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.
  • Adequate coagulation function at screening as required by the protocol.
  • Adequate hematologic function at screening as required by the protocol.
  • Adequate hepatic function at screening as required by the protocol.
  • Adequate renal function at screening as required by the protocol.
  • Able and willing to attend trial visits as required by the protocol.
  • Women of childbearing potential (WOCBP) must have a negative serum (beta-human chorionic gonadotropin [beta-hCG]) test/value at screening. Patients who are postmenopausal or permanently sterilized can be considered as not having reproductive potential.
  • WOCBP must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the entire trial, until 6 months after last BNT151 treatment.
  • A man who is sexually active with a woman of childbearing potential and has not had a vasectomy must agree to use a barrier method of birth control, e.g. either condom with spermicidal foam/gel/film/cream/suppository or partner with occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/suppository, and all men must also not donate sperm during the trial and for 6 months after receiving the last dose of BNT151.
