E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The purpose of the study is to demonstrate that sipuleucel-T can be successfully manufactured at a European manufacturing facility. Sipuleucel-T (Provenge®) is approved for use in the US by the Food and Drug Administration for the treatment of metastatic castrate resistant prostate cancer. The study sponsor, Dendreon Corporation is applying for Manufacturing Authorization in Europe. The intent of this study is to demonstrate that sipuleucel-T manufactured in Europe results in the same cellular activation as seen in sipuleucel-T produced in the US.
To evaluate successful manufacturing, samples (1-2% of the cells) will be removed from each patient’s immune cell collections before and after they are mixed with the protein. Four immune system tests will be performed on these samples and the results of these tests will be summarized descriptively for comparison to results obtained during clinical studies conducted in the US. These tests indicate if the immune cells are activated su |

E.2.2 | Secondary objectives of the trial |
The secondary objective is to evaluate the wellbeing of patients being treated with this therapy. Side effects will be carefully recorded. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Written informed consent obtained prior to the initiation of study procedures. 2. Males, age ≥ 18 years at the time of registration 3. Histologically documented adinocarcinoma of the prostate. 4. Metastatic diseaseas evidenced by soft tissue and/or bony metastases on bone scan and/or computed tomography (CT) scan of the abdomen and pelvis at any time prior to registration. (Subjects whose metastatic disease is detectable only on chest CT scan are not eligible). 5. Castrate resistant prostate cance, subjects must have current or historical evidence of disease progression concomitant with surgical or medical castration, as demonstrated by PSA progression or progression of measurable diseae or progression of non-measurable disease as defined below: - PSA: Two consecutive PSA values, at least 14 days apart, each ≥5.0 ng/mL and ≥ 50% above the minimum PSA observed during castration therapy or above the pre-treatment value if there was no response. -Measurable disease: ≥50% increase in the sum of the cross products of all measurable lesions or the development of any new lesions. The change will be measured against the best response to castration therapy or against the pre-castration studies if there was no response. -Non-measurable disease: -Soft tissue disease: the appearance of 1 or more new lesions, and/or unequivocal worsening of non-measurable disease when compared to imaging studies acquired during castration therapy or against the pre-castration studies if there was no response. -Bone disease: Apprearance of 2 or more new areas of abnormal uptake on bone scan when compared to imaging studies acquired during castration therapy or against the pre-castration studies if there was no response.Increase uptake of pre-exsisting lesions on bone scan does not constitute progression.
6. Castration levels of testosterone (≤50ng/dl; ≤1.74 nmol/L) achieved via medical or surgical castration. Surgical castration must have occurred at least 3 months prior to registration. Subjects who are not surgically castrated must be receiving medical castration therapy, have initiated such therapy at least 3 months prior to registration, and continue such therapy during their participation on this study.
7. Serum PSA ≥ 5.0 µg/L 8. ECOG performance status ≤1 9. Adequate hematologic, renal, and liver function as evidenced by the following:
White blood cell count ≥2,500 cell/µL Absolute neutrophil count ≥1000 cell/µL Platelet count ≥1000,000 cell/µL Hemoglobin ≥10.0g/dL Creatinine ≤2.0 mg/dL Total Bilirubin ≤2 x Upper limit of normal (ULN) Aspartate aminotransferase (AST, SGOT) ≤2.5 x ULN Alanine aminotransferase (ALT, SGPT) ≤2.5 x ULN
10. Negative Serology tests indicating no active infection with human immunodeficiency virus types 1 and 2 (HIV -1/2), human T cell lymphotrophic virus types 1 and 2 (HTLV –I/II), and Hepatitis B and C viruses.

E.4 | Principal exclusion criteria |
1. The presence of known brain metastases. In the case of suspected or questionable findings, the Investigator must address each findings in the subject’s medical record prior to registration
2. A requirement for systemic immunosuppressive therapy for any reason.
3. Treatment with any investigational vaccine within 2 years prior to registration
4. Any previous treatment with sipuleucel-T
5. Any previous treatment with ipilimumab (Yervoy, MDX-010, or MDX-101) or denosumab (Xgeva).
6. Pathologic long-bone fractures, imminent pathologic long-bone fracture (cortical erosion on radiography >50%), or spinal cord compression.
7. Subject with known malignancies other than prostate cancer that are likely to require treatment within 6 months of registration.
8. A history of allergic reactions attributed to compounds of similar chemical or biologic composition to sipuleucel-T or GM-CSF.
9. More than 2 chemo regimens to any time prior to registration
10. Treatment with any of the following medicated or interventions within 28 days of registration:
-Systemic corticosteroids; use of inhaled, intranasal, intra-articular, and topical steroids is acceptable, as is a short course (i.e. < 1 day) of corticosteroids to prevent a reaction to the IV contract used for CT scans.
-Non-steroidal anti-androgens (e.g., bicalutamide, flutamide, or nilutamide).
-External beam radiation therapy or major surgery requiring general anesthetic.
-Any other systemic therapy for porstate cancer including secondary hormonal therapies, such as mogestrol acetate (Megace), diethylstilbestrol (Des), and ketoconazole, medical castration therapy is not exclusionary
-Immunosuppressive therapy
-Treatment with any other investigational product
11. Any injection requiring pareteral antibiotic therapy or causing fever (temp >100.5 °F or 38.1°C) within 7 days prior to registration.
12. Any medical intervention or other condicition which, in the opinion of the Investigator or the Dendreon Medical Monitor, could compromise adherence, with study requirements or otherwise compromise the study’s objectives.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measures of the study are assays that evaluate the immune response generated by sipuleucel-T. These measures include CD54+ cell count, CD54 up-regulation, total nucleated cell count, and product viability. The results of these assays will be summarized descriptively for comparison to results obtained in clinical studies conducted in the United States and will be used to determine if sipuleucel-T can be effectively produced to the same high standard in Europe as in the United States. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Samples will be collected before and after manufacture of every sipuleucel-T dose |
|
E.5.2 | Secondary end point(s) |
Safety will be assessed by summarising adverse events, laboratory test results, vital sign measurements, ECOG performance status, and physical examination findings |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
adverse events are solicited at every subject visit and are also documented if reported in between visits
routine laboratory (safety labs) test are collected at screening and at 30 day post infusion visit for lab and PE visit.
Physical examination, vital sign measurements, ECOG performance status are performed at screening, up to 7 days before the 2nd and 3rd leukapheresis procedures, and at the study completion visit.
Visit signs are also collected 30 minutes before the infusion starts and 30 minutes after the infusion ends. |
