Randomized Controlled Trial
An adjuvant autologous therapeutic vaccine (HSPPC-96; vitespen) versus observation alone for patients at high risk of recurrence after nephrectomy for renal cell carcinoma: a multicentre, open-label, randomised phase III trial.
BACKGROUND
Treatment of localised renal cell carcinoma consists of partial or radical nephrectomy. A substantial proportion of patients are at risk for recurrence because no effective adjuvant therapy exists. We investigated the use of an autologous, tumour-derived heat-shock protein (glycoprotein 96)-peptide complex (HSPPC-96; vitespen) as adjuvant treatment in patients at high risk of recurrence after resection of locally advanced renal cell carcinoma.
METHODS
In this open-label trial, patients were randomly assigned to receive either vitespen (n=409) or observation alone (n=409) after nephrectomy. Randomisation was done in a one to one ratio by a computer-generated pseudo-random number generator, with a block size of four, and was stratified by performance score, lymph node status, and nuclear grade. Vitespen was given intradermally once a week for 4 weeks, then every 2 weeks until vaccine depletion. The primary endpoint was recurrence-free survival. The final analysis of recurrence-free survival was planned to take place after 214 or more events of disease recurrence or deaths before recurrence had occurred. Analysis was by intention to treat (ITT). This study is registered with ClinicalTrials.gov, number NCT00033904.
FINDINGS
48 patients in the vitespen group and 42 in the observation group were excluded from the ITT population because they did not meet post-surgery inclusion criteria; the ITT population thus consisted of 361 patients in the vitespen group and 367 in the observation group. Final analysis of recurrence-free survival was triggered in November, 2005. Re-review of all patients in the ITT population by the clinical events committee identified 149 actual recurrences (73 in the vitespen group and 76 in the observation group), nine deaths before recurrence (two in the vitespen group and seven in the observation group), and 124 patients with baseline metastatic or residual disease (61 in the vitespen group and 63 in the observation group). Thus, after a median follow-up of 1.9 years (IQR 0.9-2.5) in the ITT population, recurrence events were reported in 136 (37.7%) patients in the vitespen group and 146 (39.8%) in the observation group (hazard ratio 0.923, 95% CI 0.729-1.169; p=0.506). After continued follow-up until March, 2007, there had been 70 deaths in the vitespen group and 72 in the observation group (p=0.896); however, overall survival data were not mature, and patients continue to be followed up for survival. In predefined exploratory analyses by AJCC stage, recurrence events in patients with stage I or II disease were reported in 19 (15.2%) patients in the vitespen group and 31 (27.0%) in the observation group (hazard ratio 0.576, 95% CI 0.324-1.023; p=0.056). The most commonly reported adverse events in the vitespen group were injection-site erythema (n=158) and injection-site induration (n=153). One serious adverse event-autoimmune thyroiditis of grade 2 severity-was reported in the vitespen group; no treatment-related grade 3 or 4 adverse events were reported.
INTERPRETATION
No difference in recurrence-free survival was seen between patients given vitespen and those who received no treatment after nephrectomy for renal cell carcinoma. A possible improvement in recurrence-free survival in patients with early stage disease who received vitespen will require further validation.

The aim of this study was to evaluate the clinical efficacy as determined by time to progression and response rate (RR) of autologous vitespen (formerly HSPPC-96; Oncophage, Antigenics Inc., New York, NY, USA) with and without interleukin-2 (IL-2; Proleukin: Chiron, Emoryville, CA, USA) in stage IV metastatic renal cell carcinoma (RCC) patients undergoing nephrectomy. Eighty-four patients were enrolled on study, and then underwent nephrectomy and harvest of tumour tissue for use in autologous vaccine manufacture. Initial treatment schedule started approximately 4 weeks after surgery and consisted of six injections: once weekly for 4 weeks, then two injections biweekly (vaccines administered at weeks 1, 2, 3, 4, 6, 8), followed by restaging at or around week 10. Patients who had stable or responsive disease continued to receive vaccine, with four more vaccinations biweekly (at weeks 10, 12, 14, 16). Patients who had progressive disease at week-10 evaluation received four consecutive 5-day-per-week courses of 11 x 10(6) U of IL-2 subcutaneously (weeks 10, 11, 12, 13), with four doses of vitespen at 2-week intervals (at weeks 10, 12, 14, 16). At the next evaluation (week 18), patients with a complete response received two further cycles of vitespen (with IL-2 if also received during prior cycle) or until vaccine supply was exhausted. Patients with stable disease or partial response repeated their prior cycle of therapy. Disease progressors who had not yet received IL-2 began IL-2 treatment, and progressors who had already received IL-2 came off study. Of 60 evaluable patients, 2 demonstrated complete response (CR), 2 showed partial response (PR), 7 showed stable disease, and 33 patients progressed. Sixteen patients had unconfirmed stable disease. Two patients who progressed on vaccine alone experienced disease stabilisation when IL-2 was added. Treatment with vitespen did not result in a discernable benefit in the majority of patients with metastatic RCC treated in this study. Use in combination with immunoregulatory agents may enhance the efficacy of vitespen.

Comparative Study Randomized Controlled Trial
Phase III comparison of vitespen, an autologous tumor-derived heat shock protein gp96 peptide complex vaccine, with physician's choice of treatment for stage IV melanoma: the C-100-21 Study Group.
PURPOSE
To assess the antitumor activity of vitespen (autologous, tumor- derived heat shock protein gp96 peptide complexes) by determining whether patients with stage IV melanoma treated with vitespen experienced longer overall survival than patients treated with physician's choice.
PATIENTS AND METHODS
Patients (N = 322) were randomly assigned 2:1 to receive vitespen or physician's choice (PC) of a treatment containing one or more of the following: dacarbazine, temozolomide, interleukin-2, or complete tumor resection. This open-label trial was conducted at 71 centers worldwide. Patients were monitored for safety and overall survival.
RESULTS
Therapy with vitespen is devoid of significant toxicity. Patients randomly assigned to the vitespen arm received variable number of injections (range, 0 to 87; median, 6) in part because of the autologous nature of vitespen therapy. Intention-to-treat analysis showed that overall survival in the vitespen arm is statistically indistinguishable from that in the PC arm. Exploratory landmark analyses show that patients in the M1a and M1b substages receiving a larger number of vitespen immunizations survived longer than those receiving fewer such treatments. Such difference was not detected for substage M1c patients.
CONCLUSION
These results are consistent with the immunologic mechanism of action of vitespen, indicating delayed onset of clinical activity after exposure to the vaccine. The results suggest patients with M1a and M1b disease who are able to receive 10 or more doses of vitespen as the candidate population for a confirmatory study.

Review
Heat-shock proteins (HSPs) are the most abundant and ubiquitous soluble intracellular proteins. Members of the HSP family bind peptides, including antigenic peptides generated within cells. HSPs also interact with antigen-presenting cells (APCs) through CD91 and other receptors, eliciting a cascade of events that includes representation of HSP-chaperoned peptides MHC, translocation of NF-kappaB into the nuclei, and maturation of dendritic cells. These consequences point to a key role of HSPs in fundamental immunologic phenomena such as activation of APCs, indirect presentation (or crosspriming) of antigenic peptides, and chaperoning of peptides during antigen presentation. The properties of HSPs also allow them to be used for immunotherapy of cancers and infections in novel ways. This paper reviews the development and clinical trial progress of vitespen, an HSP peptide complex vaccine based on tumor-derived glycoprotein 96.
