Who may be able to join

  • Have Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1.
  • Screening tumor biopsy must be adequate for the identification of nonsynonymous somatic mutations (NSMs) by whole exome sequencing and for the development of ADXS-NEO. Biopsies may be repeated for participants whose Screening biopsies are found to be inadequate for the development of ADXS-NEO. Biopsy should be excisional, incisional or core needle. Fine needle aspiration is generally inadequate.
  • Participant population for Part A (ADXS-NEO monotherapy) is as follows:
  • Histological or cytological diagnosis of metastatic colorectal cancer (CRC) excluding known microsatellite instability (MSI)-high sub-types, metastatic squamous cell carcinoma of head and neck (SCCHN) or metastatic non-small cell lung cancer (NSCLC) that have progressed or have become intolerant to standard therapy, and whose disease may allow management with other available therapies (or a treatment break, if appropriate) for up to approximately 12 weeks following Screening tumor biopsy. More than one form of anti-tumor therapy is allowed during this interval.
  • For metastatic CRC, up to 4 lines of approved therapy in the advanced or metastatic setting are allowed, including approved antibody and targeted agent therapy. Participants may be eligible if they have received additional lines of therapy upon discussion with and approval by the Sponsor. Participants are excluded if they are known to have MSI-high tumors. If the status of microsatellite stability is not known, participants are eligible. The determination of microsatellite stability for CRC may be made by local testing on any available tissue prior to study entry.
  • For metastatic SCCHN, up to 2 lines of approved therapy in the advanced or metastatic setting are allowed, including approved antibody therapy and immunotherapy if eligible. Participants may be eligible if they have received additional lines of therapy upon discussion with and approval by the Sponsor.

About this study

Official title: A Phase 1 Dose-Escalation Study of ADXS-NEO Expressing Personalized Tumor Antigens, Alone and in Combination With Pembrolizumab in Subjects With Advanced or Metastatic Solid Tumors

This is a Phase 1, open-label, multicenter study of ADXS-NEO administered alone and in combination with pembrolizumab in participants with select advanced or metastatic solid tumors. This study will be performed in 2 phases, a safety phase (Part A and Part B) and an efficacy phase (Part C).

Read the detailed description

Mutation-derived tumor antigens, which are often unique to each participant's tumor, represent a new source of targets for cancer immunotherapy. These mutations, which arise during tumorigenesis, are expressed only by the tumor and, as such, may be recognized as newly formed antigens, or neoantigens, by the participant's T cells. The lack of expression of participant-specific tumor mutations in nonmalignant cells suggests that vaccines targeting these tumor mutations have a low risk of autoimmunity and may represent a safer therapeutic approach than many of those currently available. The development of a Listeria monocytogenes (Lm)-based vaccine that expresses these participant-specific tumor antigens and that activates tumor-killing T cells has the potential to be a highly effective form of immunotherapy. In addition, the Lm platform, because it mediates tumor control through multiple mechanisms, may exhibit more robust anti-tumor activity than other vaccine platforms. Thus, the targeting of participant-specific mutation-derived tumor antigens and the concurrent stimulation of host immunity provides a rational approach for boosting anti-tumor immunity, as monotherapy and in combination with anti-programmed cell death protein-1 (PD-1) inhibitors.
