Provenge: (250 mL)
Brand Names: U.S.
- Cellular Immunotherapy, Autologous
Sipuleucel-T is an autologous cellular immunotherapy that stimulates an immune response against an antigen (prostatic acid phosphatase [PAP]) expressed in most prostate cancer tissues. Peripheral blood is collected (~3 days prior to infusion) from the patient via leukapheresis, from which peripheral blood mononuclear cells (PBMCs) are isolated. Antigen presenting cell (APC) precursors, consisting of CD54-positive cells that include dendritic cells, are isolated from the PBMCs. The APCs are then activated (in vitro) with a recombinant human fusion protein, PAP-GM-CSF (also termed PA2024), composed of an antigen specific for prostate cancer, PAP linked to granulocyte-macrophage colony-stimulating factor and cultured for ~40 hours. The final product, sipuleucel-T, is reinfused into the patient, inducing T-cell immunity to tumors that express PAP.
Use: Labeled Indications
Prostate cancer, metastatic: Treatment of asymptomatic or minimally symptomatic metastatic castrate-resistant (hormone-refractory) prostate cancer.
There are no contraindications listed in the manufacturer’s labeling.
Note: Premedicate with oral acetaminophen 650 mg and an antihistamine (eg, diphenhydramine 50 mg) ~30 minutes prior to infusion. For autologous use only. Do not infuse until confirmation of product release has been received from the manufacturing company.
Prostate cancer, metastatic: IV: Each dose contains ≥50 million autologous CD54+ cells (obtained through leukapheresis) activated with PAP-GM-CSF; administer doses at ~2-week intervals for a total of 3 doses (Kantoff 2010). If unable to receive a scheduled infusion, an additional leukapheresis procedure will be necessary prior to continuing a course of treatment.
Refer to adult dosing.
Dosing: Adjustment for Toxicity
Acute infusion reaction: Interrupt or slow infusion rate (depending on the severity of infusion reaction); may require acetaminophen, IV H1 and/or H2 antagonists, or low-dose meperidine to manage acute symptoms.
Sipuleucel-T will arrive as a prepared patient-specific 250 mL suspension in lactated Ringer’s injection. Contents may appear clear to opaque and will be a white to red color, including shades of off-white, cream, light yellow, and orange. If clumps or clots are present, gently mix to resuspend. Do not administer if the bag leaks during handling, is damaged, or if clumps remain.
IV: For autologous use only; the identity of the patient must be matched to the patient identifiers on the infusion bag and on the “Final Product Disposition Notification” prior to infusion. Do not infuse until confirmation of product release is received from the manufacturing company. Keep the sealed infusion bag in the insulated polyurethane container inside the shipping box until ready for administration. Prior to infusion, inspect bag for signs of leaks (do not administer if leaking) or damage. Gently mix to resuspend contents; inspect for clumps or clotting; small clumps should disperse with the gentle mixing; do not administer if clumps remain. Infusion must begin prior to the expiration date and time; do NOT infuse if expired.
For IV infusion only. Infuse over ~60 minutes; infuse the entire contents of the bag. Do NOT use a cell filter for infusion. Premedicate with oral acetaminophen and diphenhydramine ~30 minutes prior to infusion. If acute infusion reaction occurs, interrupt or slow infusion rate (depending on the severity of infusion reaction); may require acetaminophen, IV H1 and/or H2 antagonists, or low-dose meperidine to manage acute symptoms. If infusion is interrupted, keep infusion bag at room temperature; do not resume if bag is retained at room temperature for >3 hours. Observe patient for at least 30 minutes after infusion.
Store in cardboard shipping carton upon arrival (the insulated container and gel packs are designed to maintain appropriate storage temperature). Do not remove the infusion bag from the insulated polyurethane container within the shipping box until administration (do not remove the insulated container from the shipping box, or open the lid of the insulated container, until administration). Product may only remain at room temperature for ≤3 hours once removed from shipping container; after removal from shipping container, do not return product to container. Infusion must begin prior to product expiration.
Immunosuppressants: May diminish the therapeutic effect of Sipuleucel-T. Management: Evaluate patients to see if it is medically appropriate to reduce or discontinue therapy with immunosuppressants prior to initiating sipuleucel-T therapy. Consider therapy modification

Concerns related to adverse effects:
• Infusion reaction: Acute infusion reactions may occur within 1 day of infusion and are usually mild or moderate for most patients; the incidence of severe reaction may be higher with the second infusion, while the third infusion is associated with a decrease in the incidence of severe reactions. Premedication with oral acetaminophen and diphenhydramine is recommended. Depending on the severity of the infusion reaction, interrupt or slow infusion rate; in clinical trials, acetaminophen, IV H1 and/or H2 antagonists, and low-dose meperidine were used to manage acute symptoms. Symptoms of acute infusion reaction may include chills, rigor, fever, bronchospasm, dyspnea, hypoxia, hypertension, tachycardia, syncope, hypotension, joint or muscle aches, nausea, vomiting, dizziness, fatigue, headache, and weakness; fever and chills usually resolved within 2 days. Observe patient for at least 30 minutes after infusion. Closely monitor patients with cardiac or pulmonary conditions during infusion.
• Thromboembolic events: Deep venous thrombosis and pulmonary embolism occurred following sipuleucel-T infusion (postmarketing reports), usually in patients with multiple risk factors for thromboembolism. Use with caution in patients at risk for thromboembolic events.
• Vascular disorders: Cerebrovascular (hemorrhagic and ischemic stroke) and cardiovascular events (myocardial infarction) have occurred; transient ischemic attacks have been reported following infusion (postmarketing reports). Such events usually occurred in patients with multiple risk factors for cerebrovascular or cardiovascular incidents.
Concurrent drug therapy issues:
• Androgen deprivation therapy: In clinical trials evaluating sipuleucel-T, patients who had androgen deprivation therapy without prior bilateral orchiectomy were continued on gonadal suppression with a luteinizing hormone-releasing hormone agonist (Higano 2009; Kantoff 2010).
• Chemotherapy: Concurrent use with chemotherapy has not been studied.
• Immunosuppressive therapy: Concurrent use with immunosuppressives (eg, corticosteroids) has not been studied; may alter the efficacy and/or safety of sipuleucel-T. Carefully evaluate patients for appropriateness of reducing or discontinuing immunosuppressive agents prior to treatment.
• Appropriate use: For autologous use only. Patient identity must be matched to the patient identifiers on the infusion bag and on the Final Product Disposition Notification (provided by manufacturer) prior to infusion. Confirmation of product release must be received from the manufacturer prior to infusion.
• Handling precautions: Apply universal precautions for product handling. Sipuleucel-T is not tested for transmissible infectious diseases; patient-specific leukapheresis collection and activated product may have a risk for infectious disease transmission.
• Sterility testing: Preliminary sterility testing is done based on a 2-day incubation period. Final (7-day incubation) testing is not available until after administration; health care providers will be notified if 7-day sterility tests are positive for microbial contamination.
• Treatment delays: If unable to receive a scheduled reinfusion, an additional leukapheresis procedure may be required; advise patients of this possibility before treatment initiation.
Monitor for infusion reaction during and for at least 30 minutes after infusion; monitor closely during infusion for patients with cardiovascular and pulmonary disease; monitor for thromboembolic and vascular events.
Animal reproduction studies have not been conducted. Not indicated for use in women.
