Abstract
Prophylactic vaccination constitutes one of the most prominent medical achievements of history. This concept was first demonstrated by the pioneer work of Edward Jenner, dating back to the late 1790s, after which an array of preparations that confer life-long protective immunity against several infectious agents has been developed. The ensuing implementation of nation-wide vaccination programs has de facto abated the incidence of dreadful diseases including rabies, typhoid, cholera and many others. Among all, the most impressive result of vaccination campaigns is surely represented by the eradication of natural smallpox infection, which was definitively certified by the WHO in 1980. The idea of employing vaccines as anticancer interventions was first theorized in the 1890s by Paul Ehrlich and William Coley. However, it soon became clear that while vaccination could be efficiently employed as a preventive measure against infectious agents, anticancer vaccines would have to (1) operate as therapeutic, rather than preventive, interventions (at least in the vast majority of settings), and (2) circumvent the fact that tumor cells often fail to elicit immune responses. During the past 30 y, along with the recognition that the immune system is not irresponsive to tumors (as it was initially thought) and that malignant cells express tumor-associated antigens whereby they can be discriminated from normal cells, considerable efforts have been dedicated to the development of anticancer vaccines. Some of these approaches, encompassing cell-based, DNA-based and purified component-based preparations, have already been shown to exert conspicuous anticancer effects in cohorts of patients affected by both hematological and solid malignancies. In this Trial Watch, we will summarize the results of recent clinical trials that have evaluated/are evaluating purified peptides or full-length proteins as therapeutic interventions against cancer.

Abstract
The present study analyzed polymorphisms of the 5' flanking region (from nt -840 to +151) of the haptoglobin gene in 120 patients with advanced non-small cell lung cancer (NSCLC) receiving personalized peptide vaccinations. In the region, six single nucleotide polymorphisms (SNPs) were confirmed, of which two, rs5472 and rs9927981, were completely linked to each other. The minor allele frequencies of rs5472/rs9927981 and rs4788458 were higher than those of the other three SNPs. The genotype frequencies of rs5472 or rs9927981 were A/A or C/C (42.5%, n=51), A/G or C/T (40.8%, n=49), and G/G or T/T (16.7%, n=20), respectively; and those of rs4788458 were T/T (34.2%, n=41), T/C (40.0%, n=48), and C/C (25.8%, n=31). The association between polymorphism rs5472/rs9927981 and prognosis, or between rs4788458 and prognosis, was analyzed further. However, no correlation was found between these SNPs and overall survival, regardless of subgroup analysis of gender, histology or concurrent therapy. These results suggest that the polymorphisms rs5472/rs9927981 and rs4788458 are not useful prognostic tools for patients with NSCLC treated with personalized peptide vaccination.

Abstract
INTRODUCTION The field of cancer immunotherapy has made dramatic progress in the past 20 years, in part due to the identification of numerous tumor-associated antigens (TAAs). We have developed a novel immunotherapeutic approach called the personalized peptide vaccine (PPV), in which a maximum of four human leukocyte antigen (HLA)-matched vaccine peptides are selected based on the pre-existing host immunity before vaccination. AREAS COVERED This review describes recent progress in the use of PPV for various types of advanced cancer. EXPERT OPINION Although various approaches for therapeutic cancer immunotherapies, including peptide-based vaccines, have been developed and clinically examined, the diverse and heterogeneous characteristics of tumor cells and host immunity seem to limit their therapeutic efficacy. Selection of suitable peptide vaccines for individual patients based on the pre-existing host immunity before vaccination could resolve this limitation and could be a rational approach for developing effective cancer vaccines.

A Phase 2 Randomized Controlled Trial of Personalized Peptide Vaccine Immunotherapy with Low-dose Dexamethasone Versus Dexamethasone Alone in Chemotherapy-naive Castration-resistant Prostate Cancer. Eur Urol 2016; 70:35-41.

Abstract
BACKGROUND It is well known that the prognosis of castration-resistant prostate cancer (CRPC) is poor, and several immunotherapeutic strategies have been applied to the clinical trials. Research on immunotherapy has been of special interest for the treatment of CRPC for years. OBJECTIVE To evaluate the safety of personalized peptide vaccine (PPV) immunotherapy and its clinical outcomes. DESIGN, SETTING, AND PARTICIPANTS A phase 2 randomized controlled trial of PPV immunotherapy with low-dose dexamethasone versus dexamethasone alone for chemotherapy-naive CRPC began in 2008. Eligible patients (prostate-specific antigen [PSA] <10 ng/ml) were human leukocyte antigen (HLA) A02, A24, or A03 superfamily positive and had asymptomatic or minimally symptomatic CRPC. Patients were allocated (1:1) to PPV plus dexamethasone (1mg/d) or to dexamethasone (1mg/d) alone. A maximum of four HLA-matched peptides (each 3mg) was selected based on the preexisting immunoglobulin G responses against the 24 warehouse peptides and administered every 2 wk. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS PSA, progression-free survival (PFS), time to initiation of chemotherapy, and overall survival (OS) were analyzed using the Kaplan-Meier method, a log-rank test, and proportional hazard analysis. RESULTS AND LIMITATIONS Overall, 37 patients received peptide vaccinations and 35 received dexamethasone alone. The primary end point was PSA PFS, which was significantly longer in the vaccination group than in the dexamethasone group (22.0 vs 7.0 mo; p=0.0076). Median OS was also significantly longer in the vaccination group (73.9 vs 34.9 mo; p=0.00084). The relatively small number of patients enrolled is the major limitation of the study. CONCLUSIONS PPV immunotherapy was well tolerated and associated with longer PSA PFS and OS in men with chemotherapy-naive CRPC. A larger phase 3 study is needed to confirm our findings. PATIENT SUMMARY We compared clinical outcomes of the treatment with personalized peptide vaccine plus dexamethasone versus dexamethasone alone. Our data provide promising evidence of clinical benefit for peptide vaccines. TRIAL REGISTRATION UMIN-CTR: 000000959.

A phase II trial of personalized peptide vaccination in castration-resistant prostate cancer patients: prolongation of prostate-specific antigen doubling time. BMC Cancer 2013; 13:613.

Abstract
Background Cancer vaccine is one of the attractive treatment modalities for patients with castration-resistant prostate cancer (CRPC). However, because of delayed immune responses, its clinical benefits, besides for overall survival (OS), are not well captured by the World Health Organization (WHO) and Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Several surrogate markers for evaluation of cancer vaccine, including prostate-specific antigen doubling time (PSADT), are currently sought. The purpose of this study was to assess prospectively the PSA kinetics and immune responses, as well as the efficacy, safety, and biomarkers of personalized peptide vaccination (PPV) in progressive CRPC. Methods One hundred patients with progressive CRPC were treated with PPV using 2–4 positive peptides from 31 candidate peptides determined by both human leukocyte antigen (HLA) class IA types and the levels of immunoglobulin G (IgG) against each peptide. The association between immune responses and PSADT as well as overall survival (OS) was studied. Results PPV was safe and well tolerated in all patients with a median survival time of 18.8 months. Peptide-specific IgG and T-cell responses strongly correlated with PSADT (p < 0.0001 and p = 0.0007, respectively), which in turn showed correlation with OS (p = 0.018). Positive IgG responses and prolongation of PSADT during PPV were also significantly associated with OS (p = 0.001 and p = 0.004) by multivariate analysis. Conclusions PSADT could be an appropriate surrogate marker for evaluation of the clinical benefit of cancer vaccine. Further randomized trials are needed to confirm these results.

Abstract
Since both tumor cells and host immune cell repertoires are diverse and heterogeneous, immune responses against tumor-associated antigens should differ substantially among individual cancer patients. Selection of suitable peptide vaccines for individual patients based on the preexisting host immunity before vaccination could induce potent anti-tumor responses that provide clinical benefit to cancer patients. We have developed a novel immunotherapeutic approach of personalized peptide vaccination (PPV) in which a maximum of four human leukocyte antigen (HLA) class IA-matched peptides are selected for vaccination among pooled peptides on the basis of both HLA class IA type and the preexisting host immunity before vaccination. In this review, we discuss our recent results of preclinical and clinical studies of PPV for various types of advanced cancer.

Abstract
Many clinical trials of peptide vaccines have been carried out since the first clinical trial of a melanoma antigen gene-1-derived peptide-based vaccine was reported in 1995. The earlier generations of peptide vaccines were composed of one to several human leukocyte antigen class I-restricted CTL-epitope peptides of a single human leukocyte antigen type. Currently, various types of next-generation peptide vaccines are under development. In this review, we focus on the clinical trials of the following categories of peptide vaccines mainly published from 2008 to 2012: (i) multivalent long peptide vaccines; (ii) multi-peptide vaccines consisting of CTL- and helper-epitopes; (iii) peptide cocktail vaccines; (iv) hybrid peptide vaccines; (v) personalized peptide vaccines; and (vi) peptide-pulsed dendritic cell vaccines.

Abstract
BACKGROUND Docetaxel-based chemotherapy (DBC) showed limited clinical efficacy for castration-resistant prostate cancer (CRPC) patients. To explore cancer vaccine as a new treatment modality, we conducted a phase II study of personalized peptide vaccine (PPV) for DBC-resistant CRPC patients. METHODS Twenty DBC-resistant CRPC patients and 22 patients with no prior DBC, as a control, were treated with PPV using peptides chosen from 31 peptides in patients, respectively. Cytokines, inflammatory markers, and immune responses were measured as candidate biomarkers. DBC-resistant CRPC patients without PPV was set as a historical control for evaluation of clinical benefit of PPV. RESULTS Median overall survival (OS) time from the first vaccination was 14.8 months or not reached in DBC-resistant CRPC patients and patients with no prior DBC (log-rank; P = 0.07), respectively. Median OS time from the first day of progression disease was 17.8 and 10.5 months in DBC-resistant CRPC patients receiving PPV and those with no PPV (P = 0.1656), respectively. Elevated IL-6 levels before vaccination was an unfavorable factor for OS of DBC-resistant CRPC patients (P = 0.0161, hazard ratio (HR): 0.024, 95% CI:0.001-0.499) as well as all 42 patients with PPV(P = 0.0011, HR: 0.212, 95% CI:0.068-0.661) by multivariable analysis. CONCLUSIONS Further clinical study of PPV is recommended for DBC-resistant CRPC patients, because of the safety and possible prolongation of MST. Control of elevated IL-6 by combined therapy may provide much better clinical outcome.

Abstract
Prostate cancer is particularly suited for active immunotherapy because of the expression of a distinctive number of antigens which are overexpressed on prostate cancer cells and cell lines. There is evidence in this disease that tumors promote immune tolerance starting early in the disease course. As such, chemotherapy, by suppressing tumors and activating immune system homeostatic mechanisms, may help overcome this tumor-induced immune tolerance. Sipuleucel-T which has recently been approved in the US, is an autologous cellular product immunotherapy that induces immune activity likely through activation of dendritic cells. This was associated with a survival benefit in the absence of significant toxicity. However, a post hoc analysis of phase III trial participants found a substantial survival benefit to receiving docetaxel some months after sipuleucel-T. However, another phase III immunotherapy trial combining a prostate cancer therapeutic vaccine GVAX plus docetaxel versus standard docetaxel therapy in advanced prostate cancer, observed a lower overall survival with the vaccine regimen. These trials highlight major unresolved questions concerning the optimum choice, dosing, and timing of chemotherapy relative to active immunotherapy and the overall merits of considering this approach. The ideal treatment approach remains unclear; advances in biomarker validation and trial design may likely improve our ability to assess biologic benefit irrespective of the development of true antitumor immunity.

Abstract
The majority of peptide-based cancer vaccines under development are for human leukocyte antigen (HLA)-A2- or -A24-positive patients. To overcome this limitation, we conducted a phase I clinical study of peptide vaccines designed for cancer patients with six different HLA-A types. Eligible patients were required to have failed prior standard cancer therapies and to be positive for the HLA-A2, -A24 or -A3 (A3, A11, A31 and A33) supertype. Three sets of 8 candidate peptides (24 peptides in total) were provided for vaccination to HLA-A2(+), HLA-A24(+) and HLA-A3(+) patients, respectively. Personalization of the vaccination peptides from the candidate pool was made by considering the patients' HLA types and pre-existing levels of IgGs to the candidate peptides. Seventeen patients were enrolled in this study. The peptide vaccinations were well tolerated in all patients with no vaccine-related severe adverse events. Augmentation of cytotoxic T lymphocyte (CTL) or IgG responses specific to the vaccinated peptides was observed in 11 or 10 out of 13 cases tested, respectively. This new type of vaccine is recommended for phase II clinical trial because of its tolerability and the immune responses to the vaccinated peptides.

Abstract
Malignant gliomas are the most common and aggressive form of brain tumour. Current combinations of aggressive surgical resection, radiation therapy and chemotherapy regimens do not significantly improve long-term patient survival for these cancers. Therefore, investigative therapies including tumour vaccines have targeted this devastating condition. This article reviews evidence and data on chemotherapy and immunotherapy for a personalized medicine approach in order to enable physicians to select the appropriate treatment for glioma patients. Dendritic cell- and peptide-based therapy for gliomas seems to be safe and without major adverse effects. Gene-modified vaccines have also shown promise in the treatment of malignant gliomas. The concept of 'personalized medicine' is currently important in oncology treatment development. Using a personalized medicine approach, it may be necessary to evaluate the molecular genetic abnormalities in individual patient tumours, and such findings should be the mainstay of immunotherapeutic strategies designed for the individual patient.

Abstract
We previously reported that personalized peptide vaccine (PPV) therapy in combination with leutenizing hormone-releasing hormone (LH-RH) analog and estramustine phosphate in certain cases is safe and capable of inducing both immune responses and clinical responses for metastatic castration-resistant prostate cancer (CRPC) patients. In the present study, PPV monotherapy was given to CRPC patients. Twenty-three patients with metastatic CRPC were treated with PPV without any additional treatment modalities, including LH-RH analogs. Samples were analyzed for peptide-specific cytotoxic T-lymphocyte (CTL) precursor analysis and peptide-reactive IgG. Toxicity and immunological and clinical responses were assessed on a three-monthly basis. Seventeen patients were available for immunological and clinical evaluation. The vaccines were well tolerated, with grade 3 erythema at injection sites in only one patient. Augmentation of CTL or IgG responses to at least one of the peptides was observed in six of 17 (35%) and 15 of 17 (88%) patients tested, respectively. Among 57 peptides used, 9 and 36 peptides induced CTL and IgG responses, respectively. Delayed-type hypersensitivity reaction was observed in eight of 17 patients. More than 30% prostate-specific antigen (PSA) decline was observed in four of 17 patients. Of these, one patient achieved a complete PSA response and another patient showed a partial PSA response with profound shrinking of lymph node metastases and prostate. The overall median survival time was 24 months (range, 5-37 months). These results suggest that PPV monotherapy appears to be safe and capable of inducing peptide-specific immune responses and clinical responses in CRPC patients. This trial was registered with University Hospital Medical Information Network (UMIN) number R000003339.

Abstract
BACKGROUND To evaluate the immunological responses of personalized peptide vaccination combined with low-dose glucocorticoids for advanced hormone refractory prostate cancer (HRPC) patients (pts). METHODS Eleven pts with advanced HRPC were treated with the vaccination and low-dose glucocorticoids; 6 pts with 10 mg/day of prednisolone (PDL) followed by 1 mg/day of dexamethasone at the time of progression, 1 pt with PDL, and 4 pts with dexamethasone. Peptide-specific cellular and humoral responses were employed to monitor pre- and post- (6th) vaccination samples. RESULTS The vaccination combined with glucocorticoids was well tolerated with no severe adverse effects. Increments of IgG responses were observed in 1 of 4 or 8 of 10 pts tested who received PDL or dexamethasone, respectively, increment of cytotoxic T lymphocyte activity was observed in 2 of 4 or 5 of 7 pts tested, respectively. Vaccination with PDL or dexamethasone resulted in a decline of PSA (at least 50%) in 1 of 7 or 6 of 10 pts with significantly longer median TTP in the dexamethasone group, respectively. CONCLUSION Vaccination combined with dexamethasone could be recommended for further clinical trials from both immunological and clinical points of view.

Abstract
Immunological treatment of cancer has made some very promising advances during the last years. Anti-cancer vaccination using peptides or peptide-pulsed dendritic cells and adoptive transfer of in vitro generated, epitope-specific T cells depend on a well-fitting interaction of HLA molecule and epitope. Accurate HLA-typing is a key factor for successful anti-cancer vaccination. No comprehensive data and no suggestion exist on the HLA-typing in this setting. We performed a systematic review of PubMed analyzing HLA-typing data in cancer vaccination trials over the last 4 years (2004-2007). Then, using the SYFPEITHI database, we calculated the peptide binding prediction of the eight most often used HLA-A*0201 binding epitopes. Finally, high-resolution typing [by sequence-specific primers (SSP)] data of a HLA-A*02 or HLA-A*24 positive population in Berlin, Germany, were analyzed. Forty-five cancer vaccination trials with 764 patients were included. Eighteen studies were performed in the USA, 13 in Europe, 12 in Asia (mainly Japan), and two in Australia. Most common diseases targeted were melanoma, prostate cancer, colorectal cancer, renal cell cancer, and breast cancer. The trials tested protocols using peptide plus adjuvants without DC or protocols using peptide-pulsed DC. In 38 trials (84%) HLA-A2 positive patients were vaccinated, in 11 studies (24%) HLA-A24 positive patients were vaccinated. Nineteen studies with 291 patients (38%) presented the HLA type as four-digit code (high-resolution), 26 studies with 473 patients (62%) presented the HLA-type in a low-resolution code. The method of HLA determination was given in six out of 45 trials (13%). Using the SYFPEITHI database we calculated the peptide binding prediction of the eight most often used HLA-A*0201 binding tumor antigen-derived epitopes for binding to HLA-A*0203. While the epitopes had a binding score of 17-28 for HLA-A*0201, the score for binding to HLA-A*0203 was zero in seven out of eight tested peptides. Only for one peptide the score was eight. Finally, we analyzed high-resolution data of HLA-A*02 and HLA-A*24 positive patients in Berlin, Germany. We found the HLA-A*0201 allele and HLA-A*2402 allele in 95%, respectively. HLA-A*0201 and HLA-A*2402 are most commonly used for peptide based vaccine in cancer. Data on HLA-typing given in the included cancer vaccine manuscripts are fractional. Only 13% report the method of HLA typing and most HLA types are given as low-resolution code. Looking at the binding of specific peptides to both the alleles, it is important to perform high-resolution typing. Further suggestions for immunogenetic laboratories and clinical tumor immunologists regarding HLA-typing for cancer vaccine trials and adoptive T cell transfer approaches are discussed.

Abstract
BACKGROUND The purpose of this study was to determine the safety and immune responses of pre-operative personalized peptide vaccine for patients with localized prostate cancer. METHOD Ten human leukocyte antigen (HLA)-A24(+) patients with localized prostate cancer received weekly personalized peptide vaccine for six times with positive peptides (up to four kinds of peptides) from 16 kinds of vaccine candidates, followed by a retropubic radical prostatectomy (RRP). Eight patients with localized prostate cancer receiving RRP served as the control group. The serum prostate-specific antigen (PSA) level, and peptide-specific cytotoxic T lymphocyte (CTL) precursor analysis by interferon-gamma production, and peptide-reactive immunoglobulin G (IgG) using an enzyme-linked immunosorbent assay were monitored during the treatment. Distributions of CD45RO(+) cells, CD8(+) T cells, and CD20(+) B cells in tissue microarray samples were studied using an immunohistochemical technique. RESULT The peptide vaccination was safe and well tolerated with no major adverse effects. Increased CTL response and the anti-peptide IgG titer were observed in the post-vaccination samples in 8 of 10 or 8 of 10 patients, respectively. The intensity of CD45RO(+) infiltrating cells in the vaccination group was significantly larger than that in the control group. CD8(+) T cell infiltration was seen only in the vaccinated group. CONCLUSION Increased immune responses, at both the circulation and tumor sites in the vaccinated group, support the further development of personalized peptide vaccines for patients with localized prostate cancer.

Abstract
Despite advances in surgery, radiation and chemotherapy, the prognosis of patients with malignant glioma is still very poor; therefore, the development of a novel therapeutic modality is essential. There are increasing reports demonstrating that systemic immunotherapy using dendritic cells or a peptide vaccine is capable of inducing an antiglioma response. Peptide-based immunotherapy strategies appear promising as an approach to successfully induce an antitumor immune response and prolong survival in patients with glioma without major side effects. Now, peptide-based immunotherapy could be a new treatment modality for patients with brain tumors.

Abstract
Radical prostatectomy and radiation therapy provide excellent localized prostate cancer (PC) control. Although the majority of prostate carcinoma is nowadays diagnosed at early stages with favourable risk features, in patients up to 30-40% it recurs within 10 years. Furthermore, the lack of effective therapies, once prostate carcinoma becomes refractory to androgen deprivation, mandates the development of alternative therapeutic options. There is a growing interest in harnessing the potency and specificity of anti-tumour immunity through the generation of fully competent dendritic cells and tumour reactive effector lymphocytes. Several strategies to treat or prevent the development of metastatic PC have been explored in clinical trials and are summarized in this review, considering also the feasibility and safety of these approaches. In some cases clinical responses were achieved showing that vaccine-primed T cells induced anti-tumour activity in vivo. The present findings and perspectives of the immunologic interventions in PC patients will be discussed.

Abstract
Therapeutic cancer vaccines have enjoyed little success so far, although many clinical trials have been conducted. Therefore, the creation of new protocols capable of inducing an objective response is required. We examined two of these protocols in the present review. The first is a personalized protocol to take into account the immunological diversity of cytotoxic T lymphocyte responses among patients. The second is a combination therapy designed to adapt to the presence of major histocompatibility complex (MHC)-loss cancer cells. The objective response rates of our classical (non-personalized) peptide vaccines were 0%, whereas that of personalized vaccines was 11.1% in the total advanced cancers and > or = 20% in malignant glioma and cervical cancers, respectively. A > or = 50% decrease in serum prostate-specific antigen (PSA) was seen in 8.7% of advanced hormone refractory prostate cancer patients by personalized vaccination alone, whereas such a decrease was seen in 54% of patients when the personalized vaccination was combined with a low dose of estramustine. Based on these experiences, we propose a personalized peptide vaccine combined with chemotherapy as a new treatment modality for cancers.

Abstract
BACKGROUND RCAS1 (receptor-binding cancer antigen expressed on SiSo cells) is known to induce apoptosis in its receptor-positive cells. The authors investigated RCAS1 expression in oral squamous cell carcinoma (SCC) and its association with the apoptosis of tumor-infiltrating lymphocytes (TILs). METHODS In 130 patients with oral SCC, the expression of RCAS1 in tumor cells was immunohistochemically examined and the apoptosis of TILs was examined by Terminal Deoxynucleotidyltransferase-mediated dUTP Nick End Labeling (TUNEL) staining. RESULTS RCAS1 was detected both on the cytoplasm and the membrane of tumor cells in 41 of 130 cases (31.5%). Focusing on the expression at the invasive front interacting with host immune cells, RCAS1 was detected in 22 of 130 cases (16.9%). The percentage of TUNEL-positive TILs in cases with RCAS1-positive SCCs was significantly higher than in cases with RCAS1-negative SCCs (P < 0.0001). CONCLUSIONS RCAS1 can be expressed on oral SCC cells and may be involved in the tumor escape from the host immune system by inducing the apoptosis of TILs.

Abstract
PURPOSE The primary goal of this phase I study was to assess the safety and immunologic responses of personalized peptide vaccination for patients with advanced malignant glioma. EXPERIMENTAL DESIGN Twenty-five patients with advanced malignant glioma (8 grade 3 and 17 grade 4 gliomas) were evaluated in a phase I clinical study of a personalized peptide vaccination. For personalized peptide vaccination, prevaccination peripheral blood mononuclear cells and plasma were provided to examine cellular and humoral responses to 25 or 23 peptides in HLA-A24+ or HLA-A2+ patients, respectively; then, only the reactive peptides (maximum of four) were used for in vivo administration. RESULTS The protocols were well tolerated with local redness and swelling at the injection site in most cases. Twenty-one patients received more than six vaccinations and were evaluated for both immunologic and clinical responses. Increases in cellular or humoral responses specific to at least one of the vaccinated peptides were observed in the postvaccination (sixth) samples from 14 or 11 of 21 patients, respectively. More importantly, significant levels of peptide-specific IgG were detected in the postvaccination tumor cavity or spinal fluid of all of the tested patients who showed favorable clinical responses. Clinical responses were 5 partial responses, 8 cases of stable disease, and 8 cases of progressive disease. The median overall survival for patients with recurrent glioblastoma multiforme in this study (n = 17) was 622 days. CONCLUSIONS Personalized peptide vaccinations were recommended for the further clinical study to malignant glioma patients.

Abstract
BACKGROUND The safety, toxicity, and immunological response of individualized peptide vaccination or human leukocyte antigen (HLA)-A24+ hormone refractory prostate cancer (HRPC) patients in combination with a low dose of estramustine were evaluated. METHODS Sixteen patients with HLA-A24+ HRPC were enrolled in the phase I/II study. Conducted immune monitorings for those patients were peptide-specific cytotoxic T lymphocyte (CTL) precursor analysis by interferon-gamma production and peptide-reactive immunoglobulin G (IgG) by an enzyme-linked immunosorbent assay. Clinical responses and quality of life (QOL) outcomes using a self-reported patient questionnaire were also evaluated. RESULTS Vaccinations were well tolerated, but all patients developed grade 1 or 2 local redness and swelling at the injection site. There was no significant immunosuppression in most cases when the peptide and a half dose (280 mg/day) of estramustine were administrated. Augmentation of peptide-specific CTL precursors or peptide-specific IgG was observed in 10 of 14 or 7 of 14 patients at 12 weeks (peptide vaccination alone), and in 6 of 8 or 10 of 12 patients at 24 weeks (during the combination therapy), respectively. All 13 patients treated, with the combination therapy, showed a decrease of serum prostate-specific antigen (PSA) level from the baseline, including six patients with a serum PSA level decrease of >or=50%. QOL outcomes were not deteriorated during the treatment. CONCLUSION These results might encourage the further evaluation of the combination of peptide vaccination and a low dose of estramustine phosphate for HLA-A24+ HRPC patients.
