Abstract
LBA5019 Background: Bevacizumab (BEV) plus interferon alpha (IFN) demonstrated a superior objective response rate and progression-free survival (PFS) versus IFN monotherapy in renal cell carcinoma (RCC) patients in 2 phase III trials. The primary objective of CALGB 90206 was to compare overall survival (OS) for advanced RCC patients receiving BEV plus IFN or IFN alone. Methods: Patients with previously-untreated, metastatic RCC with a clear cell component and Karnofsky performance status of ≥ 70% were eligible. Patients were prospectively randomized to receive BEV (10 mg/kg intravenously every 2 weeks) plus IFN (9 million units subcutaneously three times weekly) or the same dose and schedule of IFN as monotherapy. Randomization was stratified by nephrectomy status and number of MSKCC adverse features. The primary endpoint was OS, defined as the time from randomization to death due to any cause. The trial was designed with 86% power to detect a hazard ratio (HR) of 0.76, assuming a two-sided type I error of 0.05. The primary analysis was an intent-to-treat approach using the stratified log-rank statistic, and the present analysis was based on the target number of 588 deaths. Results: Between October 2003 and July 2005, 732 patients were enrolled; 369 pts to BEV plus IFN and 363 pts to IFN monotherapy. The median duration of follow up among censored patients was 46.2 months (IQR=45.2–48.2). The median OS was 18.3 months (95% CI; 16.5–22.5) for BEV plus IFN and 17.4 months (95% CI; 14.4–20.0, unstratified log rank p = 0.097) for IFN monotherapy. The stratified HR was 0.86 (95% CI; 0.73–1.01) for BEV plus IFN compared to IFN (stratified log-rank p = 0.069). The median OS for BEV plus IFN versus IFN was 32.5 vs. 33.5 months (p = 0.524) for MSKCC good risk, 17.7 vs. 16.1 months (p = 0.174) for intermediate risk and 6.6 vs. 5.7 months (p = 0.245) for poor risk patients. The median PFS was 8.4 months vs. 4.9 months (p<0.0001). Fifty-three percent of patients received subsequent systemic therapy. Conclusions: The addition of BEV to IFN significantly improves the objective response rate and PFS versus IFN monotherapy. Overall survival favored the BEV plus IFN arm, not meeting pre-defined criteria for significance. [Table: see text]

Abstract
5018 Background: Despite CG therapy, most metastatic UC patients die from their disease. Novel approaches are needed. Combining anti-angiogenic therapy with chemotherapy has improved outcomes in other malignancies, offering hope for similar improvements in UC patients. Methods: Metastatic or unresectable chemonaive UC patients (pts) with an ECOG performance status of 0–1 received C 70 mg/m2 iv d1, G 1,000–1,250 mg/m2 iv d1, 8, and B 15 mg/kg iv d1 on a q21d cycle for up to 8 cycles. Gemcitabine was reduced to 1,000 mg/m2 iv d1, 8 for all subsequent pts after 7 thromboembolic events were noted in the first 17 pts. The primary endpoint was progression free survival (PFS). The trial was designed to detect a 33% improvement in PFS from 7.5 months with traditional CG therapy to 11.25 months with CGB. Results: By December 2008, 45 pts were enrolled, with 43 evaluable for toxicity, 36 for response. Demographics include: 33 (77%) male, 10 (23%) female; median age 66 (Range: 41 - 78); 26 (60%) and 17 (40%) ECOG 0/1; 19 (44%) and 24 (56%) lymph node only / visceral metastases. PFS will be evaluated in May 2009 when all pts will have more than 6 month follow-up data. 14 (33%) and 6 (14%) pts experienced grade 3 or 4 hematologic toxicity (4 pts - thrombocytopenia, 2 pts - neutropenic fever). Grade 3 or 4 nonhematologic toxicity was observed in 24 (56%) and 9 (21%) pts (DVT/PE - 9 pts, CNS hemorrhage/proteinuria/hypertension - 1 pt each) Best RECIST response was: complete response 6 pts (17%, 95% CI 6–33%), partial response 18 pts (50%, 95% CI 33–67%); with overall response rate of 67% (95% CI 51–82%). Stable disease lasting at least 12 weeks was observed in 10 pts (28%, 95% CI 14–45%) and progressive disease in 2 pts (5%, 95% CI 1–19%). Conclusions: CGB demonstrates significant clinical activity in the first-line treatment of metastatic UC patients at the expense of considerable toxicity. The durability of disease control will be determined by assessment of PFS. A phase III trial to further define the toxicity risk vs. clinical benefit of bevacizumab addition to platinum-based doublets is planned in this population. [Table: see text]

Abstract
5039 Background: Combined mTOR and VEGF blockade is a potentially promising and rational strategy for the treatment of advanced RCC. We previously reported the phase I safety and efficacy results of CCI 779 (C) +bevacizumab (B) n RTKI naïve stage IV RCC patients (pts) (J Clin Oncol. 2007;25[18S Suppl]:5034). We now report the interim results of the phase 2 study of C+B in RTKI refractory RCC patients. Methods: Design: Open label, phase I/II study of C+B in advanced RCC pts. Patients with measurable stage IV RCC with a component of clear/conventional cell type, performance status 0–2 and good organ function were eligible. Up to two prior treatment regimens were allowed (at least one prior RTKI). Phase II dose was C = 25 mg IV weekly and B = 10 mg/kg every 2 weeks repeated in 4 week cycles. The primary objective of the phase II portion was to assess the proportion of patients who were progression-free 6 months after study entry. Secondary objectives were assessment of response rates and toxicity. Accrual goal = 40 pts. Results: Thirty-five pts have been enrolled into the phase 2 portion to date with 4 pts ineligible. Twenty-five pts are evaluable for response assessment and 29 pts are evaluable for toxicity. Baseline characteristics (N: 35): M/F: 28/7; Number of met. sites: 1/2/3+: 15/9/11; prior nephrectomy: 31; Number of prior therapies: 1 = 29; 2 = 2. Most common (>5%) Gr 3–4 AEs (N = 29) included fatigue (6), hypercholesterolemia (2), hypertriglyceridemia (2), anorexia (2), rash (2), and anemia (2). Responses were: PR/SD/PD = 4 (16%)/18 (72%)/3 (12%). Median number of cycles administered was 4. Six month progression free rates will mature by may 2009. Conclusions: C+B combination at the recommended phase 2 doses is feasible and well tolerated. Clinical benefit rates (PR/SD) in RTKI refractory RCC patients (88%) are encouraging. Data on 6 month progression-free rates are expected to mature in 4/09. Updated data on safety, response rates, and 6-month progression free rates will be presented on all evaluable patients. Correlative studies on available plasma, serum and tumor samples for angiogenic and molecular biomarkers are underway. Supported by N01-CM62205, R21 CA 119545–02, and Commonwealth Foundation.

Abstract
5138 Background: IPI is a fully human, monoclonal anti-CTLA-4 antibody capable of enhancing anti-tumor immunity. In preclinical models, XRT releases tumor antigens and enhances anti-tumor activity of CTLA-4 blockade. In the dose escalation part of this Phase I/II trial 10 mg/kg dosing of IPI with or without prior priming by single fraction XRT was feasible. We now report initial phase II results. Methods: 45 patients (pts) with mCRPC and ECOG PS of 0–1 received 10 mg/kg q3 weeks (wks) X 4 of IPI in 3 groups: (1) IPI alone n=16, (2) IPI + XRT n=15 chemotherapy naïve (NoCHEMO), and (3) IPI + XRT n=14 chemotherapy experienced (CHEMO) pts. XRT (800 cGy) was given to up to 3 involved bony sites (GI tract sparing) just prior to starting IPI. PSA was monitored monthly, with scans q 3 months. Endpoints were to confirm safety and an initial assessment of activity. Results: 17 pts (38%) experienced 26 immune-related adverse events (irAEs) including diarrhea/colitis (12), rash/pruritus (6), hepatitis (4), endocrinopathy (4). 11 pts (24%) experienced 13 ≥ Grade 3 irAEs: GI (9; 20%) and hepatitis (4; 9%); all resolved with immunosuppression. 10 of 45 pts (22%; 95% CI 10–34%) had confirmed PSA declines ≥ 50% as follows in the table below. Median time to PSA decline was 5.7 wks (r 3 to 21 wks); median duration 23 wks (r 3 to 84+ wks). In one pt dosed with IPI alone, PSA ≤ 0.05 ng/ml, as well as a CR of bone, nodal and prostate lesions continue for 54+ and 84+ wks, respectively. Conclusions: irAEs in the 10 mg/kg cohorts are similar in type and rate to IPI in melanoma. irAEs and PSA declines occurred in chemotherapy naïve and post chemotherapy patients, and with or without XRT. Addition of XRT to 10 mg/kg is well tolerated. Time to response can be delayed, with a durable median response of 23 wks. Further study of IPI in mCRPC is warranted, with or without XRT as a potential immunosupportive maneuver to augment clinical responses to IPI. [Table: see text] [Table: see text]

Abstract
10557 Background: This observational reGISTry, initiated 11/04, characterizes the evolving patterns of care for GIST, such as the recent use and approval of Imatinib mesylate (IM) in adjuvant GIST. Methods: Data from consented pts (e.g. demographics, clinical characteristics, therapy, outcomes) are entered onto a web-based database. Updated analyses are performed every 6 months (mo), with data from unique sites being compared to the aggregate. Results: 792 pts enrolled from 121 centers, 55% from community practices. 79% were diagnosed with localized tumor, 87% of which received surgery as primary treatment. 94% had c-kit testing and 4% had mutational analysis performed at any time (1.4% of the pts in the community; 7.8% in Universities). 59% of pts had mutations in KIT Exon 11, 12% in Exon 9, 3% in Exon 17, 9% in PDGFRA Exon 18 and 18% had no detectable mutations. 13% of pts from Universities were enrolled in clinical trials vs 3% in the community. 78% of pts receiving IM at any time started at 400mg qd and 70% of pts receiving Sunitinib malate (SU) started at 50mg (4 wks on, 2 wks off). 6.6% of all pts received neoadjuvant IM, for a median of 4.3 mo for those pts that have completed (81%). 120 pts (15%) received adjuvant IM (13% of the pts in the community; 17% in Universities). Prior to Jun07 (ACOSOG Z9001 adjuvant IM positive results released) 14% of eligible pts received adjuvant IM vs 29% after Jun07. Median duration of adjuvant IM was 361 days for those pts that have completed (43%). Conclusions: reGISTry is a useful tool for measuring evolving pt management patterns in GIST capturing treatment variations from standard guidelines and differentiating management in Universities from that occurring in the community. Mutational analysis and clinical trial participation are still infrequent. The starting dose of IM and SU remains 400mg and 50mg, respectively, for most pts. The use of adjuvant IM has increased after Jun 07, suggesting that prescribing habits may have been influenced by evolving study data in these pts. [Table: see text] [Table: see text]

Abstract
3018 Background: Programmed death-1 (PD-1), an inhibitory receptor expressed on activated T cells, may suppress antitumor immunity. This expansion cohort in a phase I/II trial of MDX-1106, a fully human IgG4 antibody blocking PD-1, sought to further evaluate the safety and activity of the 10 mg/kg dose. Other objectives included evaluation of pharmacokinetics (PK) and immunological effects. Methods: Patients (pts) with treatment refractory metastatic non-small cell lung cancer (NSCLC), renal cell carcinoma (RCC), colon cancer (CC), melanoma (MEL), or prostate cancer (CRPC), and no history of autoimmune disease received a single infusion of MDX-1106 at 10 mg/kg. Disease status was evaluated at week (wk) 8 by RECIST criteria. Pts with stable disease or lesional responses could receive additional MDX-1106 at wks 12 and 16. Those with PR/CR were observed without retreatment. Results: 21 pts (5 CC, 2 NSCLC, 8 MEL, 5 HRPC, 1 RCC) were treated from 10/07 to present, and 6 were retreated. No MDX-1106 related SAEs occurred. One pt developed arthritic symptoms requiring treatment, and 2 pts had asymptomatic TSH elevation. One pt with RCC had a PR after 3 doses, lasting 5+ months (mo). Lesional regressions (“mixed response”) were seen in 2 MEL pts; to date, one has received 7 doses of MDX-1106 over 15 mo without serious toxicity. Biopsy of a regressing MEL lymph node metastasis showed a moderately increased and selective CD8+ T cell infiltrate post treatment. The median serum t 1/2 of MDX-1106 was 20.6 days, which was roughly 50% longer than observed for lower doses. There was no evidence of immunogenicity based on HAHA development. Interestingly, in contrast to PK results, flow cytometric analysis demonstrated sustained occupancy of 60–80% PD-1 molecules on T cells for at least 3 mo following a single dose. Analyses of circulating lymphocyte subsets and tumor B7-H1 expression are in progress. Conclusions: Intermittent dosing of MDX-1106 at 10 mg/kg demonstrated clinical activity against RCC and MEL without serious toxicity. Therapy with MDX-1106 to enhance endogenous antitumor immunity, either alone or combined with other immunological therapies, warrants further study. [Table: see text]

Abstract
BACKGROUND We demonstrated that circulating tumor cell (CTC) number at baseline and follow-up is an independent prognostic factor in metastatic colorectal cancer (mCRC). This analysis was undertaken to explore whether patient and treatment characteristics impact the prognostic value of CTCs. PATIENTS AND METHODS CTCs were enumerated with immunomagnetic separation from the blood of 430 patients with mCRC at baseline and on therapy. Patients were stratified into unfavorable and favorable prognostic groups based on CTC levels of > or = 3 or <3 CTCs/7.5 ml, respectively. Subgroups were analyzed by line of treatment, liver involvement, receipt of oxaliplatin, irinotecan, or bevacizumab, age, and Eastern Cooperative Oncology Group performance status (ECOG PS). RESULTS Seventy-one percent of deaths have occurred. Median follow-up for living patients is 25.8 months. For all patients, progression-free survival (PFS) and overall survival (OS) for unfavorable compared with favorable baseline CTCs is shorter (4.4 versus 7.8 m, P = 0.004 for PFS; 9.4 versus 20.6 m, P < 0.0001 for OS). In all patient subgroups, unfavorable baseline CTC was associated with inferior OS (P < 0.001). In patients receiving first- or second-line therapy (P = 0.003), irinotecan (P = 0.0001), having liver involvement (P = 0.002), >/=65 years (P = 0.0007), and ECOG PS of zero (P = 0.04), unfavorable baseline CTC was associated with inferior PFS. CONCLUSION Baseline CTC count is an important prognostic factor within specific subgroups defined by treatment or patient characteristics.

Abstract
4504 Background: Treatment options for metastatic NET, including islet cell carcinoma (ICC) and carcinoid tumor (CT), are limited. These tumors frequently express vascular endothelial growth factor receptor-2 (VEGFR-2) and platelet derived growth factor receptor receptor-β (PDGFR-β). Sorafenib, a small-molecule inhibitor of the VEGFR-2 and PDGFR-β tyrosine kinase domains, is a rational targeted therapy to evaluate in NET. Methods: Eligibility criteria included: ECOG PS = 2, = 1 prior chemotherapy, good organ function and signed informed consent. Prior interferon and prior or concurrent octreotide at a stable dose were allowed. Pts unable to take oral medications, with uncontrolled hypertension or with symptomatic coronary artery disease were excluded. Pts received sorafenib 400 mg po BID. Primary endpoint was response by RECIST in two cohorts (ie, CT and ICC) using separate 2-stage phase II designs. Results: 93 pts were enrolled: (50 CT, 43 ICC). For pts evaluable for the primary endpoint, 4 of 41 (10%) CT pts and 4 of 41 (10%) ICC pts had a PR. There were 3 minor responses (MR = 20–29% decrease in sum of target lesion diameters) in CT pts and 9 MRs in ICC pts for PR+MR rate of 17% for CT pts and 32% for ICC pts. For pts evaluable, 6-month progression-free survival was observed in 8/20 CT and 14/23 ICC pts. Grade 3–4 toxicity occurred in 43% of pts, with skin (20%), GI (7%) and fatigue (9%) most common. Translational studies from tumor tissue will be presented. Conclusions: Sorafenib at 400 mg po BID has modest activity in metastatic neuroendocrine tumors, with frequent grade = 3 toxicity.

Abstract
15102 Background: There is currently no standard therapy for patients with unresectable or metastatic biliary tract cancers. Gemcitabine has been shown to be active against these tumors with a 20–30% response in various phase II studies. Gemcitabine is also synergistic with platinum compounds. Aim: We conducted a Phase II study of gemcitabine plus carboplatin in patients with unresectable or metastatic choloangiocarcinoma or gallbladder cancer to assess the regimen’s safety and efficacy. Methods: Since 3/2002, 49 (48 evaluable) patients were treated with gemcitabine at 1000 mg/m2 IV over 30 minutes days 1 and 8 with carboplatin at AUC 5 IV on day 1 of a 21 day cycle. There were 34 women and 15 men enrolled. Ages ranged from 34 to 87 with a median age of 65 years. Results: Best radiologic responses - 5CR, 9 PR, 24 stable disease and 10 progression. CR+PR 14/48 (29.2%) and stable disease 24/48 (50%). Toxicity: Hematological toxicities: Grade 3 neutropenia 33%, febrile neutropenia 0.02%, anemia 12.5% and thrombocytopenia 14.6%. Grade 4 hematological toxicites were rare - neutropenia 0.04%, and thrombocytopenia 0.06%. Non-hematologic toxicities were generally mild (fatigue, edema, nausea, vomiting, elevated liver enzymes, electrolyte abnormalities). Except for one patient who had depression there were no grade 4 non-hematological toxicity. Grade 3 non- hematological toxicites were also rare occurring only in 1 to 3 patients. Conclusions: Gemcitabine and carboplatin is active against biliary cancer and is highly tolerable. This study is being supported by Eli Lilly & Co. No significant financial relationships to disclose.

Abstract
15595 Background: CNTO 95 has demonstrated preclinical antitumor activity through binding to multiple av integrins, resulting in growth inhibition indirectly through anti-angiogenic effects as well as directly by inhibiting tumor cell proliferation. The target, av integrins, has been demonstrated by immunohistochemistry in a large proportion of human prostate cancer tissues. Docetaxel and prednisone have become a standard of care for HRPCP. The primary objective of this study was to evaluate the safety of combining CNTO 95 with this standard. Methods: Patients received day 1 infusions of 75 mg/m2 docetaxel together with twice daily oral prednisone in every 3 week cycles, with weekly infusions of either 5 or 10 mg/kg of CNTO 95 for 7 weeks beginning with the second docetaxel cycle, then CNTO 95 on the days of docetaxel thereafter. Patients were monitored for safety and PSA. Radiologic tumor assessments were performed at least every 4 cycles. Results: Six patients have received docetaxel and prednisone with CNTO 95 at either 5 mg/kg (n=3) or 10 mg/kg (n=3). In the 5 mg/kg group, 1 received 8 cycles then withdrew consent because of fluctuating PSA levels; 1 received 9 cycles then had soft tissue disease progression; and 1 has completed 9 cycles and remains on study treatment. In the 10 mg/kg group, all patients remain on study and have received 7, 6, and 6 cycles of treatment, respectively. There were no unexpected toxicities and only one Grade 3 toxicity (febrile neutropenia) attributed to docetaxel. A 50% decline in PSA occurred in 1 patient treated in the 10 mg/kg group. Conclusions: The combination of standard dose docetaxel and prednisone with 10 mg/kg of CNTO 95 was well tolerated and 3 new patients are planned to be treated with these doses on this study. Further study is warranted. [Table: see text]

Abstract
4560 Background: Oxaliplatin (OX), gemcitabine (GEM) and capecitabine (CAP) are all active agents against various gastrointestinal and other malignancies and have different mechanisms of action and toxicity profiles. This Phase I study aims to determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLT) associated with this triplet regimen. Methods: The modified Fibonacchi 3/cohort dose escalation schema was used to determine the MTD and DLT of OX, GEM and CAP. Oxalipaltin [85–100 mg/m2] IV over 2 hours and gemcitabine [800–1,000 mg/m2] were given at a constant rate infusion of 10 mg/m2/min on days 1 & 15, while CAP [600–800 mg/m2] was given PO BID on days 1–7 and 15–21. 1 cycle = 28 days. Pharmacogenomic correlates including ERCC2, GSTP1, TYMS, TS del and TSER G>C were also obtained. A structured neurological toxicity assessment and questionnaire was also performed. Once MTD was established, additional patients were treated at the MTD and pharmacokinetic studies were performed on these additional patients. Results: 30 patients (M:F 2:1; 23% non-caucasian) with median age of 62 (range: 38–78) and PS of 0–1 were enrolled from 3/05 to 8/06. All patients had advanced GI malignancies (19 pancreatic, 6 biliary, 2 duodenal, 1 gastric, 1 esophageal, 1 GI unknown primary). Dose levels, # patients, DLT and best responses are tabulated below. Conclusions: The MTD of this triplet regimen is OX at 100 mg/m2, GEM at 800 mg/m2 days 1 & 15 with CAP at 800 mg/m2 PO BID days 1–7, 15–21. DLTs for this regimen include grade 3 fatigue and dyspnea as well as Grade 4 thrombocytopenia. CR is achieved in 2 patients (cholangiocarcinoma and pancreatic), while a patient with a GI unknown primary achieved PR. Several patients with pancreatic cancer achieved prolonged SD. An exploration of any association of toxicities and response with pharmacogenomic correlates is ongoing. A Phase II study in patients with pancreaticobiliary cancers is planned. This study is supported by Sanofi-Aventis Pharmaceuticals. [Table: see text] [Table: see text]

Abstract
5034 Background: The mammalian target of rapamicin (mTOR) and vascular endothelial growth factor (VEGF) pathways are critically involved in the pathogenesis and progression of clear cell renal cell carcinoma. Methods: The goal of the phase I portion of the trial was to determine the maximum tolerated dose (MTD) and dose limiting toxicity (DLT) of the combination of the mTOR inhibitor CCI-779 (C) and the anti-VEGF monoclonal antibody Bevacizumab (B). Patients with measurable stage IV clear cell RCC, performance status 0–2 and good organ function were eligible. Up to two prior treatment regimens were allowed. Treatment consisted of 25 mg IV weekly C and escalating IV doses of B (level 1= 5 mg/kg; level 2= 10 mg/kg) every other week. A cycle was defined as 4 weeks. Results: A total of 10 male and 2 female patients, median age 66 yrs (50–77) were enrolled to the phase I portion of the trial. PS: 0/1= 6/6; prior nephrectomy = 10; prior systemic therapy = 7 (prior cytokine therapy = 6); Number of metastatic sites: 1/2/≥3 = 2/2/8; one patient (out of 6) in dose level 1 experienced DLT which consisted of grade 3 hypertriglyceridemia. 1/6 patient in dose level 2 experienced DLT with grade 3 mucositis. Other grade 3 toxicities that were not DLTs included hypertension, proteinuria, hemorrhage, nausea/vomiting, dehydration, anorexia, pneumonitis, anemia, and hypophosphatemia. The best responses in the 12 evaluable patients included 7 PRs and 3 SDs. One patient had PD due to symptomatic deterioration and in one patient response information is not available at the time of this submission. Conclusions: Combination therapy with CCI-779 and Bevacizumab is safe and shows promising clinical antitumor activity. The recommended phase II dose is CCI-779 25 mg/week with bevacizumab 10 mg/kg every other week. The phase II study in stage IV renal cell cancer patients refractory to FDA approved receptor tyrosine kinase inhibitors is under way. The goals of the phase II portion are to determine the proportion of patients who have not had disease progression at 6 months, safety, response rates and correlative biomarker studies including determination of the tumor’s VHL-HIF-VEGF status, PTEN/AKT expression, plasma angiogenic activity and angiogenic cytokines.

Abstract
4573 Background: The treatment of patients with a rising PSA after definitive local therapy is controversial. Patients are reluctant to undergo androgen suppression due to side effects and interest focuses on the timing and intensity of additional therapy. The use of peripheral androgen blockade in this setting is appealing. Methods: Patients with a rising PSA after definitive local therapy were enrolled in a multi-institutional trial. Accrual of 101 patients lasted from Sept 30, 1998 to July 16, 2001. All patients had undergone previous definitive local therapy at least 1 year, and no more than 10 years prior to enrollment. All patients had a repeated rising PSA, above 1 ng/ml, with no detectable evidence of recurrent disease. CT and bone scans were negative. Patients received a combination of oral therapy consisting of Finasteride, at a dose of 5 mg/day, and Flutamide, at a dose of 250 mg TID. Results: The median age was 71, with a median baseline testosterone level of 322 ng/dl. A >80% PSA decline was seen in 91/94, (97%) of the patients. Three other patients had PSA declines of 77%, 73% and 38%, all of which were maintained for at least 28 days. The median time to PSA nadir was 3.2 months. The current median follow-up is 59 months. To date, only 22 patients have progressed, with 47 patients still on peripheral androgen blockade. Eight patients have died without progression, and 22 patients went off therapy for other reasons not related to progression. Also noted were patients showing PSA responses to Flutamide withdrawal, and per protocol remaining on Finasteride. Toxicity to date remains very mild. Conclusions: Peripheral androgen blockade showed excellent activity produced durable PSA responses in this select group of patients. While the clinical significance of a decline in PSA alone is not fully understood_the durability of these PSA responses is encouraging. The median duration of progression free survival and overall survival has not been reached, and is likely to be longer than five years. Quality of life data is undergoing further analysis. This report supports further study of less aggressive treatments for patients who have only a rising PSA after definitive local therapy. No significant financial relationships to disclose.
