Sipuleucel-T Based Autologous Cellular Immunotherapy for Advanced Prostate Cancer

Clinicaltrials.gov ID: NCT05806814

Conditions

Metastatic Castration-Resistant Prostate Cancer (mCRPC)

Summary

Proposed immunotherapy with an extended course of Sipuleucel-T treatment may induce a more robust immune response and improve the anti-cancer efficacy of Sipuleucel-T in patients with metastatic Castration-Resistant Prostate Cancer (mCRPC).

Detailed Description

This open-label, pilot trial aims to evaluate the feasibility of Sipuleucel-T given in three doses at weeks 0, 2, and 12-14; and to investigate the changes in immune response in mCRPC patients who are getting an extended course of Sipuleucel-T treatment.

Eligibility Criteria

Inclusion Criteria:

1. Men ≥ 18 years of age
2. Prostate cancer with history of metastasis
3. Candidates for Sipuleucel-T treatment are defined as those with asymptomatic or minimally symptomatic metastatic castrate resistant prostate cancer
4. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
5. Life expectancy of ≥ 6 months

Exclusion Criteria:

1. Previously received Sipuleucel-T (Provenge®)
2. Known malignancies other than prostate cancer likely to require treatment within 6 months following registration
3. A requirement for systemic immunosuppressive therapy (>10mg Prednisone daily or equivalent)
4. A history of allergic reactions attributed to compounds of similar chemical or biologic composition to Sipuleucel-T or GM-CSF
5. Any infection requiring antibiotic therapy within 1 week prior to registration

Study Plan

Extended course of Sipuleucel-T treatment

  • BIOLOGICAL:

    Sipuleucel-T

    Description:

    Three doses of Sipuleucel-T, each containing a minimum of 50 million autologous CD54+ cells activated with PAP-GM-CSF, given at week 0, 2, and 12-14.

Outcome Measures

Primary Outcome Measures

Proportion of patients completing 3 doses of Sipuleucel-T immunotherapy.

Time Frame: up to 5 months

Proportion of subjects who have detectable elevated IgG level and/or T-cell proliferation from baseline to the follow-up of extended course of Sipuleucel-T immunotherapy.

Time Frame: up to 12 Months

Secondary Outcome Measures

Evaluate the mean difference in immune response to Sipuleucel-T treatment among different racial groups.

Time Frame: up to 12 months

Evaluate the potential tumor response based on the changes in serum PSA at baseline and within 30 days of last dose.

Time Frame: up to 12 Months
