A phase II study of gemcitabine and oxaliplatin in advanced transitional cell carcinoma of the bladder

Cisplatin-based chemotherapy is recommended for use as first-line treatment for patients with advanced transitional cell carcinoma of the bladder. Unfortunately, 30–50 % of patients are ineligible for cisplatin due to renal insufficiency. Oxaliplatin is a less nephrotoxic platin which can be used for patients with impaired renal function. We carried out a phase II study of gemcitabine (1,200 mg/m²) in combination with oxaliplatin (100 mg/m²) given on days 1 and 14 every 28 days (GEMOX) in predominantly cisplatin-‘unfit’ stage IV transitional cell bladder cancer patients to determine whether this combination exhibited a clinical activity profile similar to cisplatin plus gemcitabine. Eighteen patients with a median GFR of 49 ml/min were enrolled. GEMOX treatment led to a 36 % response rate in assessable patients. Median progression-free survival was 4.9 months, with a median overall survival (OS) of 10.4 months and a one-year survival rate of 44.4 %. GEMOX in bladder cancer patients exhibited a tolerable side effects profile, with thrombocytopenia as the most frequent grade 3/4 toxicity. These findings suggest that GEMOX is an active combination in advanced bladder cancer patients with reduced renal function.     

Gemcitabine and oxaliplatin (GEMOX) in gemcitabine refractory advanced pancreatic adenocarcinoma: a phase II study

Gemcitabine and oxaliplatin (GEMOX) are active as first-line therapy against advanced pancreatic cancer. This study aims to evaluate the activity and tolerability of this combination in patients refractory to standard gemcitabine (GEM). A total of 33 patients (median age of 57) were included with locally advanced and metastatic evaluable diseases, who had progressed during or following GEM therapy. The GEMOX regimen consisted of 1000 mg m(-2) of GEM at a 100-min infusion on day 1, followed on day 2 by 100 mg m(-2) of oxaliplatin at a 2-h infusion; a cycle that was given every 2 weeks. All patients received at least one cycle of GEMOX (median 5; range 1-29). Response by 31 evaluable patients was as follows: PR: 7/31(22.6%), s.d. > or = 8 weeks: 11/31(35.5%), s.d. < 8 weeks: 1/31(3.2%), PD: 12/31(38.7%). Median duration of response and TTP were 4.5 and 4.2 months, respectively. Median survival was 6 months (range 0.5-21). Clinical benefit response was observed in 17/31 patients (54.8%). Grade III/IV non-neurologic toxicities occurred in 12/33 patients (36.3%), and grade I, II, and III neuropathy in 17(51%), 3(9%), and 4(12%) patients, respectively. GEMOX is a well-tolerated, active regimen that may provide a benefit to patients with advanced pancreatic cancer after progression following standard gemcitabine treatment.     

A phase II study of gemcitabine and docetaxel therapy in patients with advanced urothelial carcinoma

BACKGROUND: The objectives of the current study were to evaluate the safety and efficacy of gemcitabine plus docetaxel in patients with unresectable (Stage T4 or >/= N1) metastatic or locally advanced transitional cell carcinoma (TCC) of the urothelial tract. METHODS: A total of 27 patients were enrolled in the current multisite study, which was performed within the University of California-Los Angeles Community Oncology Research Network. The first 10 patients in the study received 800 mg/m(2) of gemcitabine intravenously on Days 1, 8, and 15 of a 28-day treatment cycle. In addition, on Day 1, the first 10 patients received 80 mg/m(2) of docetaxel intravenously after completion of the gemcitabine infusion. Because of dose-limiting toxicity (neutropenia), the initial dose of docetaxel was reduced to 60 mg/m(2) for the remaining patients who entered the study (n = 17 patients). RESULTS: Neutropenia was the most common adverse event that occurred in patients at the Grade 3 level (in 10 of 27 patients; 37.0%) and the Grade 4 level (in 6 of 27 patients; 22.2%). There were no other adverse events at the Grade 4 toxicity level. Twenty-five of 27 patients (92.6%) completed more than 1 cycle of combination therapy and were evaluated for antitumor responses. The frequency of objective clinical responses was 33.3% (9 of 27 patients). Complete responses to therapy were observed in 2 of 27 patients (7.4%), and partial responses were observed in 7 of 27 patients (25.9%). The median duration of response was 20 weeks (range, 12+ weeks to 152 weeks). The median survival duration was 52 weeks (range, 12 weeks to 160+ weeks). Four of 27 patients (14.8%) remained alive at the time of the current data analysis. CONCLUSIONS: The results of the current study suggested that combination therapy with gemcitabine and docetaxel was an effective treatment for patients with unresectable (Stage T4 or >/= N1) metastatic or locally advanced TCC of the urothelial tract. Gemcitabine plus docetaxel appeared to be tolerated well, and treatment-related toxicities were limited to hematologic toxicities. Because cisplatin-containing regimens are contraindicated for patients with impaired renal function, the gemcitabine plus docetaxel combination may prove to be an effective and well tolerated treatment option for these patients.     

Gemcitabine plus oxaliplatin (GEMOX) in patients with advanced hepatocellular carcinoma (HCC): results of a phase II study

BACKGROUND: New systemic therapies are needed to improve the prognosis of patients with advanced-stage hepatocellular carcinoma (HCC). In a Phase II trial involving previously untreated patients with advanced HCC, the more favorable schedule from a previous pilot study was evaluated. METHODS: Thirty-four patients with previously untreated advanced-stage HCC were prospectively enrolled. The GEMOX regimen consisted of gemcitabine 1000 mg/m(2) on Day 1 and oxaliplatin 100 mg/m(2) on Day 2. The treatment was repeated every 2 weeks until disease progression or limiting toxicity. RESULTS: Thirty-two patients were assessable for efficacy and 33 for toxicity. In all, 323 treatment cycles were administered. No toxic deaths occurred. Hematological grade 3-4 toxicity consisted of thrombocytopenia (27% of patients) and neutropenia (24%), including 2 febrile neutropenia and anemia (9%). Grade 3 oxaliplatin-induced neurotoxicity was observed in 3 (9%) patients. The overall response rate was 18% (95% confidence interval [CI]: 8-34) and disease stabilization was observed in 58% of patients (including 5 minor responses), giving a disease control rate of 76%. Median progression-free and overall survival times were, respectively, 6.3 months (95% CI: 4.3-10.1 months) and 11.5 months (95% CI: 8.5-14.3 months). Treatment was significantly more effective in patients with nonalcoholic cirrhosis than in those with alcoholic cirrhosis. CONCLUSIONS: The GEMOX regimen seems to be well tolerated and active in advanced HCC, especially in patients with underlying nonalcoholic liver disease. A Phase II study of the GEMOX regimen plus cetuximab is ongoing.     

Gemcitabine plus oxaliplatin combination (GEMOX regimen) in pretreated patients with advanced non-small cell lung cancer (NSCLC): a multicenter phase II study

PURPOSE: To evaluate the activity and tolerance of gemcitabine in combination with oxaliplatin (GEMOX regimen) in pretreated patients with advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS: Thirty-two patients with advanced NSCLC who had disease progression after a cisplatin- and taxane-based front-line regimen were treated with gemcitabine (1500 mg/m(2) on days 1 and 8) and oxaliplatin (130 mg/m(2) on day 8) every 3 weeks. The patients' median age was 62 years and the performance status (WHO) was 0 for 11, 1 for 17 and 2 for 4 patients. The treatment was second line for 22 (69%) and >or=third line for 10 (31%) patients. RESULTS: Partial response was achieved in 5 (16%) patients, stable disease in 8 (25%) and progressive disease in 19 (59%). Two patients with stable disease and one patient with progressive disease while on previous chemotherapy experienced a partial response with GEMOX regimen. The median duration of response was 2.5 months (range, 1-11.5), the median time to tumor progression 3 months (range, 1-18) and the median survival 5.6 months (range, 1-31). Grade III neutropenia occurred in five (16%) patients, grade III thrombocytopenia in two (6%) and grade III anemia in three (9%); moreover, grades II-III asthenia was reported in eight (25%) patients and grades II-III neurotoxicity in three (9%). CONCLUSION: The GEMOX combination is a relatively active and well tolerated second-line regimen in NSCLC patients pretreated with a taxane- and/or platinum-based chemotherapy.     

Gemcitabine and oxaliplatin (GEMOX) in patients with cisplatin-refractory germ cell tumors: a phase II study.

BACKGROUND: To investigate the efficacy and toxicity of the combination of gemcitabine and oxaliplatin (GEMOX) in patients with relapsed or cisplatin-refractory non-seminomatous germ cell tumors (NSGCT). PATIENTS AND METHODS: Twenty-nine patients with relapsed or cisplatin-refractory NSGCT were treated with gemcitabine 1000 mg/m2 on days 1 and 8 followed by oxaliplatin 130 mg/m2 on day 1 every 3 weeks for a maximum of six cycles. Twenty-four patients (83%) were considered refractory and five (17%) absolutely refractory to cisplatin. RESULTS: Twenty-eight patients were assessable for response. Overall, nine patients (32%) achieved a favourable response (complete response, four; partial response, five). One of the complete responders relapsed after 7 months and went into disease-free status lasting for 11+ months after resection of lung metastases. The rest of the complete responders are continuously disease-free at 14+, 19+ and 28+ months with the study regimen plus or minus surgery. One of the complete responders had absolutely cisplatin-refractory disease and another one presented with a late relapse. Toxicity was primarily hematological and generally manageable: 62% of patients experienced grade 3/4 neutropenia, 10% neutropenic fever and 41% grade 3/4 thrombocytopenia. Non-hematological toxicity consisted mainly of nausea/vomiting. Three patients (10%) developed grade 3 neurotoxicity and discontinued treatment. CONCLUSIONS: The combination of GEMOX is an active, moderately toxic and easily administered regimen in patients with relapsed or cisplatin-refractory NSGCT. The 14% long-term disease-free status accomplished in this heavily pretreated patient population is quite encouraging.     

A phase II trial of pemetrexed plus gemcitabine in locally advanced and/or metastatic transitional cell carcinoma of the urothelium.

BACKGROUND: Both pemetrexed and gemcitabine have single-agent activity in bladder cancer, but the combination of these two drugs has not been previously evaluated for safety and efficacy in this disease. Thus, the objectives in the current study were to determine overall response rate (ORR), progression-free survival, overall survival and safety and toxicity in chemonaive patients with locally advanced and/or metastatic transitional cell carcinoma of the urothelium. PATIENTS AND METHODS: Gemcitabine 1250 mg/m2 was administered over 30 min i.v. on days 1 and 8, and pemetrexed 500 mg/m2 over 10 min i.v. on day 8 after gemcitabine, every 21 days. RESULTS: Sixty-four patients were enrolled, 11 female and 53 male, median age 65 years (range 38-81), median WHO performance status of 1. Visceral metastases were present in 55% of patients. ORR among 47 patients evaluable for response was 28% (95% CI 16% to 43%) and ORR for the intention-to-treat population was 20% (95% CI 11% to 32%) with three CR and 10 PR. Median response duration was 11.2 months and median overall survival 10.3 months (95% CI 8.1-14.6 months). CTC grade 3/4 hematologic toxicities included anemia (19%), thrombocytopenia (9%), neutropenia (38%), febrile neutropenia (17%) and neutropenic sepsis (3%). Grade 3/4 non-hematologic toxicities included elevated transaminases (12%), dyspnea (8%), fatigue (8%) and stomatitis (5%). There was one toxic death due to neutropenic sepsis. CONCLUSIONS: The combination of pemetrexed and gemcitabine had a manageable safety profile. However, efficacy was apparently not superior to that of single-agent gemcitabine.     

A phase II study of gemcitabine in combination with oxaliplatin as first-line chemotherapy in patients with inoperable biliary tract cancer

Purpose   The aim of this study is to investigate the efficacy and safety of gemcitabine and oxaliplatin combination chemotherapy as first-line therapy in patients with inoperable biliary tract cancer (BTC). Methods   The treatment of this non-randomized phase II study consisted of gemcitabine 1,000 mg/m² intravenously (i.v.) on day 1 and oxaliplatin 85 mg/m² i.v. on day 2 every 2 weeks until disease progression, unaccep toxicity or patients’ refusal. Results   From Sept 2006 to Oct 2007, 40 patients were enrolled. In the ITT analysis, the objective response rate was 15.0% and the disease control rate was 52.5%. The median overall survival (95% CI) was 8.5 months (6.4–10.7) and the time to progression was 4.2 months (0.5–7.9). For the 305 cycles, observed grade 3/4 toxicity was uncommon. Conclusions  Gemcitabine and dose adjusted oxaliplatin combination chemotherapy had moderate anti-tumor activity and was well tolerated as a first-line treatment for patients with inoperable BTC.     

Phase II study of bortezomib in patients with previously treated advanced urothelial tract transitional cell carcinoma: CALGB 90207

Background: There is no standard second-line treatment for advancedurothelial carcinoma (UC). Response rates to second-line chemotherapyfor advanced UC are low and response duration is short. Bortezomibis a proteasome inhibitor with preclinical activity againstUC. Patients and methods: Treatment consisted of bortezomib 1.3mg/m² i.v. twice weekly for two consecutive weeks, followedby a 1-week break. The primary end point was objective responserate (complete response + partial response) by Reponse EvaluationCriteria in Solid Tumors criteria. Secondary end points includedsafety, toxicity, and progression-free and overall survival. Results: In all, 25 patients with advanced UC previously treatedwith combination chemotherapy were enrolled in a multi-institutionalsingle-arm trial from December 2003 through April 2005. Only29% of patients had node-only metastases. Grade 3/4 drug-relatedtoxic effects included thrombocytopenia (4%), anemia (8%), lymphopenia(8%), sensory neuropathy (6%), hyperglycemia (4%), hypernatremia(4%), fatigue (4%), neuropathic pain (6%), dehydration (4%),and vomiting (4%). No objective responses were observed [95%confidence interval (CI) = 0–12]. The median time to progressionwas 1.4 months (95% CI = 1.1–2.0 months), and the mediansurvival time was 5.7 months (95% CI = 3.6–8.4 months).There were no treatment-related deaths. Conclusion: Although bortezomib is well tolerated, it does nothave antitumor activity as second-line therapy in UC.

A phase I/II study of lenalidomide in combination with sunitinib in patients with advanced or metastatic renal cell carcinoma

BackgroundThis phase I/II study was conducted to determine the maximum tolerated dose (MTD), safety, and efficacy of lenalidomide plus sunitinib in metastatic renal cell carcinoma (RCC) patients.Patients and methodsPatients with histologically confirmed, metastatic RCC were treated with 10 mg/day lenalidomide plus 37.5 mg/day sunitinib, orally in 21-day cycles. Doses were escalated to determine the MTD in phase I, with additional patients planned at this dose in phase II. Primary end points were MTD and response rate.ResultsSixteen patients received a median of 2, 3, and 5 cycles in cohort 1 [lenalidomide 10 mg (days 1–21) and sunitinib 37.5 mg (days 1–21)], cohort 2 [lenalidomide 10 mg (days 1–21) and sunitinib 37.5 mg (days 1–14)], and cohort 3 [lenalidomide 15 mg (days 1–21) and sunitinib 37.5 mg (days 1–14)], respectively. Median treatment durations were 41, 63, and 97 days for lenalidomide; and 41, 57, and 97.5 days for sunitinib. The MTD was found to be continuous dosing of lenalidomide 10 mg/day plus sunitinib 37.5 mg/day for 14 of 21 days. Dose-limiting toxicities included neutropenia, leukopenia, thrombocytopenia, asthenia, atrial fibrillation, and increased transaminases. The most frequent grade 3–4 treatment-emergent adverse events were hematologic, including neutropenia and leukopenia. One patient achieved partial response, and seven had stable disease of which three were confirmed at subsequent tumor assessments. B cells and several T-cell subsets were modulated versus baseline.ConclusionThe dose schedules of lenalidomide and sunitinib evaluated in this study were not well tolerated; cumulative toxicity precluded enrollment at the MTD.     

Gemcitabine and oxaliplatin combination: a multicenter phase II trial in unfit patients with locally advanced or metastatic urothelial cancer.

BACKGROUND: Up to 50% of patients with bladder cancer cannot be treated with cisplatin because they are considered unfit due to poor renal function. Gemcitabine and oxaliplatin are active, nonnephrotoxic therapies with nonoverlapping toxicity profiles that provide an alternative therapy for this group of patients. PATIENTS AND METHODS: In a multicenter study, patients received gemcitabine 1200 mg/m(2) on days 1 and 8 and oxaliplatin 100 mg/m(2) on day 8 every 21 days. Eligible criteria were creatinine clearance >30 ml/min and/or Eastern Cooperative Oncology Group (ECOG) performance status of two or less. RESULTS: Forty-six patients were assessable for response and toxicity. Median age was 69 years (range 52-85), median ECOG two (range 0-2). Median number of metastatic sites was 2 (range 1-6). Median creatinine clearance was 50.73 ml/min (range 30-87). A total of 187 cycles were given with a median of 5 (range 1-6). Hematological toxicity was mild with grade 3-4 peripherical neuropathy occurring in 4% of patients. Overall response rate was 48% (three complete response, 19 partial response, seven stable disease and 17 progressive disease). Median time to disease progression was 5 months. CONCLUSION: Gemcitabine-oxaliplatin is an active and tolerable combination with response rate that merits further study in patients with impaired renal function but good performance status.     

Platinum-free combination chemotherapy in patients with advanced or metastatic transitional cell carcinoma

BACKGROUND: Platinum-based regimens have improved response rates and survival in patients with advanced transitional cell carcinoma (TCC) of the urothelial tract. However, the toxicities of platinum-based chemotherapy are considerable. Regimens with reduced toxicity that are applicable to a broader group of TCC patients without sacrificing activity therefore are of interest. METHODS: Because gemcitabine, paclitaxel, and methotrexate have each been reported to possess single-agent activity in this disease, the authors evaluated the tolerability and efficacy of fixed doses of paclitaxel (100 mg/m(2) over 3 hours) and methotrexate (30 mg/m(2)) with escalating doses of gemcitabine (800-1000 mg/m(2)), all given on Days 1 and 8 every 21 days, in patients with previously untreated unresectable or metastatic TCC. RESULTS: Twenty-five patients were enrolled. Two patients were ineligible and were excluded from analysis. Because no dose-limiting toxicity occurred in the first 4 patients who were given gemcitabine at a dose of 800 mg/m(2), the gemcitabine dose was escalated to 1000 mg/m(2) in the next 21 patients. Of the 21 patients assessable for response, 6 had achieved a complete response (CR) and 6 had achieved a partial response, for an overall response rate of 57%. An additional patient was converted to a CR surgically. The median overall and progression-free survival times were 18 months and 9.2 months, respectively. Toxicity was predominantly neutropenia: Grade 3 in 9 patients (39%) and Grade 4 in 4 patients (17%) (according to the Southwest Oncology Group Toxicity Criteria, version 12/1994). One patient died of septic shock associated with febrile neutropenia after three cycles. CONCLUSIONS: The regimen of gemcitabine, paclitaxel, and methotrexate at this dose and schedule was found to possess activity in patients with locally advanced or metastatic TCC. Further studies of this regimen are warranted.     

A phase II trial of R115777, an oral farnesyl transferase inhibitor, in patients with advanced urothelial tract transitional cell carcinoma

BACKGROUND: R115777 is a potent farnesyl transferase inhibitor and has significant antitumor effects in vitro and in vivo. METHODS: The objective of the current study was to determine the objective response proportion in patients with metastatic transitional cell carcinoma (TCC) of the urothelial tract who received treatment with R115777 at a dose of 300 mg orally given twice daily for 21 days followed by 7 days of rest for every 4-week cycle. Thirty-four patients with TCC were enrolled in this Phase II study. Patients were allowed to have received a maximum of one prior systemic chemotherapy regimen, not including chemoradiation or neoadjuvant chemotherapy. All patients were required to have an Eastern Cooperative Oncology Group performance status of 0-2 and adequate bone marrow, hepatic, and kidney function. RESULTS: Twice daily administration of oral R115777 was tolerated well. R115777 was absorbed rapidly after oral administration. Grade 3-4 neutropenia (according to the National Cancer Institute Common Toxicity Criteria [version 2.0]) was observed in 5 patients (15%). Grade 3-4 nonhematologic toxicity was rare, consisting of rash and diarrhea in 1 patient each. Two patients (6%) without prior chemotherapy demonstrated partial responses. Thirteen patients (38%) achieved disease stabilization according to World Health Organization criteria that lasted a median of 4 months. No complete responses were observed. CONCLUSIONS: The objective response rate of R115777 was not sufficient to warrant future investigation in TCC as a single agent. Preliminary evidence of the activity of R115777 in 2 chemotherapy-naive patients may warrant further investigation in combination with first-line chemotherapy.     

Gemcitabine combined with oxaliplatin (GEMOX) in advanced biliary tract adenocarcinoma: a GERCOR study.

BACKGROUND: Since gemcitabine-oxaliplatin (GEMOX) has been used in pancreatic adenocarcinoma, we studied its activity and tolerability in advanced biliary tract adenocarcinoma (ABTA). PATIENTS AND METHODS: Consecutive adult patients with confirmed ABTA were recruited from four centers. Those in group A had performance status (PS) 0-2, bilirubin <2.5x normal and received GEMOX as first-line chemotherapy. Those in group B had PS >2 and/or bilirubin >2.5x normal and/or prior chemotherapy. All received gemcitabine 1000 mg/m2 as a 10 mg/m2/min infusion on day 1, followed by oxaliplatin 100 mg/m2 as a 2-h infusion on day 2, every 2 weeks. RESULTS: Tumor sites were gallbladder (19), extrahepatic bile ducts (5), ampulla of vater (3) and intrahepatic bile ducts (29). Results for group A (n = 3) were: objective response 36% [95% confidence interval (CI) 18.7% to 52.3%], stable disease 26%, progressive disease 39%, median progression-free survival (PFS) 5.7 months and overall survival (OS) 15.4 months. Results for group B (n = 23) were: objective response 22% (95% CI 6.5% to 37.4%), stable disease 30%, progressive disease 48%, PFS 3.9 months and OS 7.6 months. National Cancer Institute Common Toxicity Criteria grade 3-4 toxicities were neutropenia 14% of patients, thrombocytopenia 9%, nausea/vomiting 5% and peripheral neuropathy 7%. CONCLUSION: The GEMOX combination is active and well tolerated in ABTA.     

Weekly regimen of epirubicin and paclitaxel as second-line chemotherapy in patients with metastatic transitional cell carcinoma of urothelial tract: results of a phase II study

Until recently, there was no standard second-line treatment for advanced urothelial carcinoma. Although included in first-line regimens, role of anthracyclines was never investigated as second-line therapy. Single-agent paclitaxel showed modest results in this setting. The purpose of this study was to assess the efficacy and toxicity of concomitant weekly administration of epirubicin plus paclitaxel in patients with metastatic urothelial carcinoma previously treated with platinum-based regimens. Between March 2004 and May 2008, thirty-five consecutive pretreated patients with metastatic transitional cell carcinoma of the urothelial tract were enrolled. Median age was 64 years (range 45-72 years), and median ECOG PS was 1 (range 0-1). Patients received epirubicin 25 mg/m(2) and paclitaxel 80 mg/m(2) on days 1, 8, and 15 every 28 days. All patients were evaluable for efficacy and toxicity; a median of four cycles was administered. One patient (3%) showed a complete response (CR), nine patients (26%) had partial response, stable disease was observed in eight patients (23%) for a disease control rate (DCR) of 52%. The median time to progression (TTP) was 7.6 months (95% CI 3.2-10.7 months) with a median survival time (MST) of 12.6 months (95% CI 4.6-18.8 months). Toxicity was acceptable and manageable: no cases of febrile neutropenia occurred and only two patients (6%) developed grade 3 neuropathy. This is the first study that evaluated the role of anthracyclines in combination with paclitaxel as second-line chemotherapy in metastatic transitional cell carcinoma of the urothelium. Our findings show the substantial activity of weekly regimen of paclitaxel and epirubicin: due to its manageable profile of toxicity, this schedule could represent an interesting therapeutic option in previously treated patients with advanced urothelial carcinoma.     

A phase II trial of gemcitabine plus carboplatin in advanced transitional cell carcinoma of the urothelium

Background

Setting priorities for the funding of new anti-cancer agents is becoming increasingly complex. The funding of adjuvant trastuzumab for breast cancer has brought this dilemma to the fore. In this paper we review external factors that may influence decision-making bodies and present a case study of media response in Ontario, Canada to adjuvant trastuzumab for breast cancer.

Methods

A comprehensive search of the databases of Canadian national and local newspapers and television was performed. Articles pertaining to trastuzumab in adjuvant breast cancer as well as 17 other anti-cancer drugs and indications were retrieved. The search period was from the date when individual trial results were announced to the date funding was made available in Ontario.

Results

During the 2.6 months between the release of the trastuzumab results to funding approval in Ontario, we identified 51 episodes of media coverage. For the 17 other drugs/indications (7 breast and 10 non-breast), the median time to funding approval was 31 months (range 14–46). Other recent major advances in oncology such as adjuvant vinorelbine/cisplatin for resected NSCLC and docetaxel for advanced prostate cancer received considerably less media attention (17 media reports for each) than trastuzumab. The median number of media reports for breast cancer drugs was 4.5 compared to 2.5 for non-breast cancer drugs (p = 0.56).

Conclusion

Priority-setting for novel anti-cancer agents is a complex process that tries to ensure fair use of constrained resources to fund therapies with the best evidence of clinical benefit. However, this process is subject to external factors including the influence of media, patient advocates, politicians, and industry. The data in this case study serve to illustrate the significant involvement one (or all) of these external factors may play in the debate over priority-setting.     

Weekly chemotherapy with docetaxel, gemcitabine and cisplatin in advanced transitional cell urothelial cancer: a phase II trial.

PURPOSE: To evaluate the efficacy and toxicity of a combination of weekly docetaxel, gemcitabine and cisplatin in advanced transitional cell carcinoma (TCC) of the bladder. PATIENTS AND METHODS: Thirty-five chemotherapy-na?ve (adjuvant and neoadjuvant chemotherapy was allowed) patients with advanced TCC received intravenous docetaxel 35 mg/m2, gemcitabine 800 mg/m2 and cisplatin 35 mg/m2, on days 1 and 8 every 3 weeks. Prophylactic granulocyte-colony stimulating factor was given from days 3 to 6 and days 10 to 15, anti-emetics were used routinely. RESULTS: Most (27) patients (77.1%) had a performance status of 0 to 1 and eight (22.9%) had received prior adjuvant or neoadjuvant cisplatin-based chemotherapy. In the intention-to-treat analysis, the objective response rate was 65.6% [23/35 patients, 95% confidence interval (CI) 47.8% to 80.9%]. Ten patients (28.5%) achieved a complete response (95% CI 14.6% to 46.3%) and 13 (37.1%) a partial response (95% CI 21.5% to 55.0%). Median survival time was 15.5 months, median duration of response was 10.2 months and median time to progression was 8.9 months. Ten patients (28.5%) developed grade 3/4 neutropenia, including five (14.3%) who experienced febrile neutropenia, which was successfully treated. Grade 3/4 anaemia and thrombocytopenia occurred in 20% and 25.7% of patients, respectively; four patients required platelet transfusions. There were no treatment-related deaths. CONCLUSIONS: Weekly docetaxel, gemcitabine plus cisplatin is a highly effective treatment for chemotherapy-na?ve advanced TCC, and causes only moderate toxicity. This regimen should be considered as a suitable option that deserves further prospective evaluation through randomised phase III trials.     

A phase II study of mitoguazone and vinblastine in advanced transitional cell carcinoma of the urinary tract

This is a comparative study to evaluate response rate to mitoguazone (MGBG) and vinblastine (VLB) in 52 evaluable patients with advanced transitional cell carcinoma of the urinary tract. Of 38 patients with measurable disease, two of 18 (11%) on MGBG had partial remission (95% confidence interval: 0.01, 0.35), whereas four of 20 (20%) responded on the VLB arm (95% confidence level: 0.06-0.44). Both responses on the MGBG arm were seen in patients given prior chemotherapy. Side effects of both drugs were significant, with 46% of patients given VLB developing severe or life-threatening hematologic toxicity. Data indicate that both drugs, as single agents, are probably inferior to cisplatin for control of advanced transitional cell carcinoma of the urinary tract.
