Study Details

Study Description

Brief Summary

TiTAN-1 is a first-in-human study of GEN-011, an experimental treatment being evaluated in adult patients with advanced cancer. GEN-011 is a T cell therapy made specific to each patient, using the patient's own circulating immune cells. First, Genocea confirms which cancer proteins are recognized already by each patient's T cells using ATLAS™. Then, immune cells that recognize these cancer proteins are multiplied many times (a process called PLANET™) to create a personalized GEN-011 cell therapy, which is given back to the patient in one or more intravenous (IV) infusions.

Detailed Description

TiTAN-1 is an open-label, multicenter, first-in-human Phase 1 study of GEN-011 in patients with melanoma, non-small cell lung cancer (NSCLC), squamous cell carcinoma of the head and neck (SCCHN), urothelial carcinoma (UC, bladder, ureter, urethra, or renal pelvis), renal cell carcinoma (RCC), small cell lung cancer (SCLC), cutaneous squamous cell carcinoma (CSCC), or anal squamous cell carcinoma (ASCC). Patients will be enrolled into one of 2 cohorts. One cohort will receive a multiple low dose (MLD) regimen of GEN-011 to be given without lymphodepletion, and a second cohort will receive a single high dose (SHD) regimen of GEN-011 after lymphodepletion. Regardless of cohort, each dose of GEN-011 will be followed by a course of interleukin-2 (IL-2) as costimulatory therapy.

GEN-011 is an investigational, personalized neoantigen adoptive cell therapy (ACT) that is being developed by Genocea for the treatment of adult patients with advanced solid tumors. A proprietary tool developed by Genocea called ATLAS™ (Antigen Lead Acquisition System) will be used to identify true immunogenic neoantigens from each patient's tumor that are recognized by their own CD4 and/or CD8 T cells. ATLAS-identified neoantigens will be used to stimulate and select autologous T cells collected by apheresis to generate an adoptive cell product ex vivo.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Multiple Low Dose (MLD)

GEN-011 is administered by IV infusion at 4-week intervals, up to 5 doses maximum. Each dose is followed by IL-2 administration. MLD patients will not undergo lymphodepletion.

Biological: GEN-011
Personalized neoantigen adoptive cell therapy (ACT)

Drug: IL-2
Cytokine
Other Names:
  • Interleukin-2
  • Experimental: Single High Dose (SHD)

    GEN-011 is administered as a single IV infusion at the maximum available cell yield, after the patient completes a fludarabine/cyclophosphamide lymphodepletion regimen. The single GEN-011 dose is followed by IL-2 administration.

    Outcome Measures

    Primary Outcome Measures

    1. Incidence of Treatment-Emergent Adverse Events [2 years after first GEN-011 infusion]

      Adverse events will be graded according to the NC Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0

    Secondary Outcome Measures

    1. T cell responses to GEN-011 [2 years after first GEN-011 infusion]

      Antigen-specific immunogenicity assays

    2. Duration of response [2 years after first GEN-011 infusion]

      Measured by RECIST

    3. Progression-free survival [2 years after first GEN-011 infusion]

      Length of time without disease progression

    4. Overall survival [From first GEN-011 infusion through study completion, at least 2 years]

      Length of time patient remains alive

    Other Outcome Measures

    1. Immune cell phenotyping [2 years after first GEN-011 infusion]

      Classification of peripheral immune cells via flow cytometry

    2. Epitope Spread [4 weeks after first GEN-011 infusion]

      Tumor mutations will be identified by gene sequencing at multiple timepoints, and comparing the differences in mutations over time

    3. Tumor infiltrating immune cell [2 years after first GEN-011 infusion]

      Quantitation and phenotyping of immune cells in proximity to tumor cells using immunohistochemistry
