Project description:ObjectivesThe aim of this study was to evaluate the efficacy and tolerability of the combination of cisplatin-gemcitabine with concurrent thoracic radiotherapy for locally advanced non-small cell lung cancer (LA-NSCLC).MethodsThis was a phase II, multicenter, open-label, single-arm trial in treatment-naïve patients with stage IIIA and IIIB LA-NSCLC. After three induction cycles with gemcitabine 1250 mg/m(2) plus cisplatin 80 mg/m(2), two concurrent chemoradiotherapy cycles with gemcitabine 300 mg/m(2), cisplatin 80 mg/m(2), and radiotherapy (63 Gy) were administered. The primary endpoint was response rate after induction chemotherapy followed by concurrent chemoradiotherapy. Secondary endpoints included time to progressive disease (TtPD), overall survival (OS), and safety.ResultsOverall, 49 patients (median age 63.4 years; 73.5% male; Karnofsky performance status scores of 80, 85, 90, and 100 [16.3%, 2.0%, 49.0%, and 32.7%, respectively]; disease stage IIIA or IIIB 28.6% and 71.4%, respectively) were enrolled and treated. Response rate was 38.8% (95% confidence interval [CI] 25.2-53.8%). Median TtPD was 11.4 months (95% CI 9.4-12.9). Median OS was 21.8 months (95% CI 17.5-26.0), with 1- and 2-year survival rates of 70.8% and 43.7%, respectively. Overall, six patients discontinued from study treatment due to adverse events (AEs), of which two were serious AEs. The most relevant grade 3/4 AEs were neutropenia and thrombocytopenia in induction chemotherapy and chemoradiotherapy, and grade 3 events related to radiation in acute chemoradiotherapy, e.g. dysphagia, radiation pneumonitis, and radiation esophagitis.ConclusionsInduction chemotherapy followed by concurrent chemoradiotherapy with gemcitabine (300 mg/m(2)) and cisplatin was associated with acceptable toxicity. The observed median OS time was 21.8 months. Response evaluation was difficult as in many cases it was not possible to differentiate tumor progression from local radiofibrosis.

Project description:PurposeAntiangiogenic agents combined with chemotherapy have efficacy in the treatment of unresectable malignant pleural mesothelioma (MPM). Cediranib (AstraZeneca, Cheshire, United Kingdom), a vascular endothelial growth factor receptor and platelet-derived growth factor receptor inhibitor, demonstrated therapeutic potential in a prior phase I trial. We evaluated a phase II trial for efficacy.Patients and methodsSWOG S0905 (ClinicalTrials.gov identifier: NCT01064648) randomly assigned cediranib or placebo with platinum-pemetrexed for six cycles followed by maintenance cediranib or placebo in unresectable chemotherapy-naïve patients with MPM of any histologic subtype. Primary end point was Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 progression-free survival (PFS). Secondary end points included overall survival, PFS by modified RECIST v1.1, response (modified RECIST and RECIST v1.1), disease control, and safety/toxicity. The trial was designed to detect a difference in RECIST v1.1 PFS at the one-sided 0.1 level using a stratified log-rank test.ResultsNinety-two eligible patients were enrolled (75% epithelioid and 25% biphasic or sarcomatoid). The cediranib arm had more grade 3 and 4 diarrhea, dehydration, hypertension, and weight loss. Cediranib improved PFS by RECIST v1.1 (hazard ratio, 0.71; 80% CI, 0.54 to 0.95; P = .062; 7.2 months v 5.6 months) and increased modified RECIST v1.1 response (50% v 20%; P = .006). By modified RECIST v1.1, cediranib numerically increased PFS (hazard ratio, 0.77; 80% CI, 0.59 to 1.02; P = .12; median, 6.9 months v 5.6 months). No significant difference in overall survival was observed.ConclusionThe addition of cediranib to platinum-pemetrexed improved PFS by RECIST v1.1 and response rate by modified RECIST in patients with unresectable MPM. Whereas adding antiangiogenics to chemotherapy has been a successful strategy for some patients, the cediranib toxicity profile and small incremental survival benefit precludes additional development in MPM.

Project description:This phase II study examined the pathological complete response (pCR) rate and safety of two gemcitabine-based combinations administered sequentially in breast cancer. We also examined gene expression profiles from tumor biopsies to identify biomarkers predictive of response. Methods: Indian women with large or locally advanced breast cancer received 4 cycles of gemcitabine 1200 mg/m2 plus doxorubicin 60 mg/m2 (Gem+Dox), then 4 cycles of gemcitabine 1000 mg/m2 plus cisplatin 70 mg/m2 (Gem+Cis), and surgery. To examine dynamic changes in molecular profiles after one dose of therapy, we used three alternate sequences during cycle 1 (Gem d1, 8; Dox d2; Gem d1, 8; Dox d1; or Gem d2, 8; Dox d1). Results: Of 65 women (median age 46) treated, 13 (24.5% of 53 patients with surgery) had a pCR and 22 (33.8%) had a complete clinical response. Patients who received Gem d1, 8 and Dox d2 in cycle 1 (20/65) reported more toxicities, with G3/4 neutropenic infection/febrile neutropenia (7/20) and vomiting (5/20) as the most common cycle 1 events. Four drug-related deaths occurred. 46/65 patients yielded successful pretreatment gene expression profiles. Ten-fold cross-validated supervised analyses identified gene expression patterns that predicted with >73% accuracy (1) clinical complete response after eight cycles, (2) overall clinical complete response, and (3) pCR. Conclusions: This neoadjuvant regimen showed strong activity. A subset of patients receiving Gem d1, 8 and Dox d2 experienced unacceptable toxicity, whereas patients on other sequences had more manageable safety profiles. The predictive gene expression patterns may provide a method for selecting patients most likely to benefit from gemcitabine-containing neoadjuvant therapy.

Project description:BACKGROUND:The prognosis of patients with unresectable or metastatic biliary tract cancer (BTC) is unacceptably low. This study aimed to determine the efficacy, safety and predictive biomarkers of the immune checkpoint inhibitor nivolumab in combination with chemotherapy in advanced BTCs. METHODS:In this open-label, single-arm, phase II trial, a chemotherapy and immunotherapy combination consisting of gemcitabine 1000 mg/m2, cisplatin 75 mg/m2 and nivolumab 3 mg/kg was administered every 3 weeks for up to six cycles. Maintenance treatment with gemcitabine plus nivolumab was administered to patients achieving disease control following the combination therapy. The primary outcome was the objective response rate. Secondary outcomes included safety, disease control rate (DCR), progression-free survival (PFS) and overall survival (OS). The exploratory objective was to assess biomarkers for predicting clinical response and prognosis. RESULTS:Thirty-two patients with a median age of 60 (range 27-69) years were enrolled. As of September 31, 2019, the median follow-up was 12.8 (95% CI 10.8 to 14.8) months. Twenty-seven response-evaluable patients received a median of 4 (IQR, 3-6) cycles of combination therapy, of whom 15 (55.6%) patients achieved an objective response, including 5 (18.6%) with a complete response (CR), and the DCR was 92.6%. Of the six patients in cohort A who were resistant to gemcitabine-based or cisplatin-based chemotherapy, one achieved CR and one achieved partial response. Thirteen of 21 chemotherapy-naive patients (61.9%) in cohort B achieved an objective response. The median PFS of all patients in cohorts A+B was 6.1 months. The median OS was 8.5 months, with a 33.3% 12-month OS rate. The most frequent grade 3 or higher adverse events were thrombocytopenia (56%) and neutropenia (22%). Fitness might be a biomarker for predicting clinical response. On-therapy changes in serum soluble FasL, MCP-1 and interferon-? were correlated with prognosis. CONCLUSIONS:Nivolumab in combination with gemcitabine and cisplatin offers promising efficacy and a manageable safety profile for patients with advanced BTCs. TRIAL REGISTRATION NUMBER:NCT03311789.

Project description:Purpose Neoadjuvant chemotherapy followed by radical cystectomy (RC) is a standard of care for the management of muscle-invasive bladder cancer (MIBC). Dose-dense cisplatin-based regimens have yielded favorable outcomes compared with standard-dose chemotherapy, yet the optimal neoadjuvant regimen remains undefined. We assessed the efficacy and tolerability of six cycles of neoadjuvant dose-dense gemcitabine and cisplatin (ddGC) in patients with MIBC. Patients and Methods In this prospective, multicenter phase II study, patients received ddGC (gemcitabine 2,500 mg/m2 on day 1 and cisplatin 35 mg/m2 on days 1 and 2) every 2 weeks for 6 cycles followed by RC. The primary end point was pathologic downstaging to non-muscle-invasive disease (< pT2N0). Patients who did not undergo RC were deemed nonresponders. Pretreatment tumors underwent next-generation sequencing to identify predictors of chemosensitivity. Results Forty-nine patients were enrolled from three institutions. The primary end point was met, with 57% of 46 evaluable patients downstaged to < pT2N0. Pathologic response correlated with improved recurrence-free survival and overall survival. Nineteen patients (39%) required toxicity-related dose modifications. Sixty-seven percent of patients completed all six planned cycles. No patient failed to undergo RC as a result of chemotherapy-associated toxicities. The most frequent treatment-related toxicity was anemia (12%; grade 3). The presence of a presumed deleterious DNA damage response (DDR) gene alteration was associated with chemosensitivity (positive predictive value for < pT2N0 [89%]). No patient with a deleterious DDR gene alteration has experienced recurrence at a median follow-up of 2 years. Conclusion Six cycles of ddGC is an active, well-tolerated neoadjuvant regimen for the treatment of patients with MIBC. The presence of a putative deleterious DDR gene alteration in pretreatment tumor tissue strongly predicted for chemosensitivity, durable response, and superior long-term survival.

Project description:NC-6004 is a nanoparticle developed using micellar technology that can improve release of cisplatin, a standard treatment for many cancer types, and achieve selective distribution to tumors. Here, in the Phase II portion of this study, the activity, safety, tolerability, and effects on quality of life of NC-6004 in combination with gemcitabine was examined in 34 squamous non-small cell lung carcinoma (NSCLC) patients, 50 biliary tract cancer patients, and 13 bladder cancer patients. All patients received 135 mg/m2 NC-6004 on day one and 1,250 mg/m2 gemcitabine on days one and eight. The median progression-free survival was 3.9 months in NSCLC patients, 4.3 months in biliary tract cancer patients, and 6.8 months in bladder cancer patients fit for cisplatin treatment. The most frequently reported Grade 3 Treatment Emergent Adverse Events across all cohorts were nausea, anemia and neutropenia, and hyponatremia. Quality of life measures for patients who received the combined therapy were generally consistent with expectations for patients undergoing chemotherapy. Overall, combined NC-6004 and gemcitabine treatment resulted in long-lasting antitumor activity and had a favorable safety profile, suggesting that it should be investigated further as a therapy for various types of cancer.

Project description:We investigated the efficacy of cetuximab when added to induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) in patients with locally advanced head and neck squamous cell carcinoma.Patients were randomized to receive three cycles of docetaxel and cisplatin (TP regimen) with or without cetuximab (TP plus cetuximab [CTP] vs. TP) as induction chemotherapy. Patients in the CTP arm received CCRT with cetuximab and cisplatin, whereas patients in the TP arm received cisplatin alone. The primary endpoint was the objective response rate (ORR) after induction chemotherapy.Overall, 92 patients were enrolled. The ORRs for induction chemotherapy in the CTP and TP arms were not different (81% vs. 82%). Adding cetuximab lowered the completion rate of induction chemotherapy and CCRT and resulted in more frequent dose reductions of the induction chemotherapy, although this did not reach statistical significance. In the CTP and TP arms, respectively, the 3-year progression-free survival (PFS) rates were 70% and 56% (p = .359), and the overall survival (OS) rates were 88% and 74% (p = .313). When limited to patients who completed induction chemotherapy, 3-year PFS rates of 78% and 59% (p = .085) and OS rates of 94% and 73% (p = .045) were observed in the CTP and TP arms, respectively.Adding cetuximab to sequential treatment did not increase the treatment efficacy and resulted in greater toxicity. In the intent-to-treat population, neither PFS nor OS was improved by the addition of cetuximab to sequential treatment; however, a suggestion of improved survival outcomes was observed in patients completing cetuximab-containing induction chemotherapy.

Project description:Lessons learnedTreatment with temozolomide and BCNU was associated with substantial response and survival rates for patients with unresectable anaplastic glioma, suggesting potential therapeutic alternative for these patients. The optimal treatment for unresectable large anaplastic gliomas remains debated.BackgroundThe optimal treatment for unresectable large anaplastic gliomas remains debated.MethodsAdult patients with histologically proven unresectable anaplastic oligodendroglioma or mixed gliomas (World Health Organization [WHO] 2007) were eligible. Treatment consisted of BCNU (150 mg/m2 ) and temozolomide (110 mg/m2 for 5 days) every 6 weeks for six cycles before radiotherapy.ResultsBetween December 2005 and December 2009, 55 patients (median age of 53.1 years; range, 20.5-70.2) were included. Forty percent of patients presented with wild-type IDH1 gliomas, and 30% presented with methylated MGMT promoter. Median progression-free survival (PFS), centralized PFS, and overall survival (OS) were 16.6 (95% confidence interval [CI], 12.8-20.3), 15.4 (95% CI, 10.0-20.8), and 25.4 (95% CI, 17.5-33.2) months, respectively. Complete and partial responses under chemotherapy were observed for 28.3% and 17% of patients, respectively. Radiotherapy completion was achieved for 75% of patients. Preservation of functional status and self-care capability (Karnofsky performance status [KPS] ≥70) were preserved until disease progression for 69% of patients. Grade ≥ 3 toxicities were reported for 52% of patients, and three deaths were related to treatment. By multivariate analyses including age and KPS, IDH mutation was associated with better prognostic for both PFS and OS, whereas MGMT promoter methylation was associated with better OS.ConclusionThe association of BCNU and temozolomide upfront is active for patients with unresectable anaplastic gliomas, but toxicity limits its use.

Project description:PurposeAlthough gemcitabine and carboplatin (GCa) is a standard option for patients with advanced urothelial cancer (UC) who are ineligible for cisplatin, outcomes remain poor. This trial evaluated the efficacy and safety of bevacizumab with GCa in advanced UC.Patients and methodsPatients with Karnofsky performance status of 60% to 70%, creatinine clearance less than 60 mL/min, visceral metastasis, or solitary kidney were eligible and received a lead-in dose of bevacizumab 10 mg/kg followed 2 weeks later by gemcitabine 1,000 mg/m(2) on days 1 and 8 and carboplatin at area under the [concentration-time] curve (AUC) 5.0 or 4.5 and bevacizumab 15 mg/kg on day 1 every 21 days for six cycles. Patients achieving at least stable disease (SD) continued bevacizumab 15 mg/kg every 21 days for 18 additional cycles. The study was powered to detect a 50% improvement in median progression-free survival (PFS) over a historical control.ResultsFifty-one patients, median age 67 years (range, 42 to 83 years), were enrolled onto the study and were evaluable for toxicity. Twenty (39%) experienced grade 3 to 4 toxicity, and 10 (20%) had thromboembolic events (deep venous thrombosis or pulmonary embolism). Four received one or fewer cycles leaving 47 evaluable for outcomes. Twenty-three (49%) achieved response (three complete; 20 partial), and 11 had SD. Median PFS was 6.5 months (95% CI, 4.7 to 7.8 months); PFS was greater in the carboplatin AUC 5.0 group (P = .04). Median overall survival (OS) was 13.9 months.ConclusionThe 95% one-sided lower confidence bound of 4.77 months for median PFS did not meet the predesignated PFS of more than 4.8 months considered sufficient for further study. Median OS was greater than expected. An ongoing phase III trial in patients who are eligible for therapy with cisplatin will define the role of bevacizumab in UC.

Project description:PurposeNeoadjuvant gemcitabine and cisplatin (GC) followed by radical cystectomy (RC) is standard for patients with muscle-invasive bladder cancer (MIBC). On the basis of the activity of atezolizumab (A) in metastatic BC, we tested neoadjuvant GC plus A for MIBC.MethodsEligible patients with MIBC (cT2-T4aN0M0) received a dose of A, followed 2 weeks later by GC plus A every 21 days for four cycles followed 3 weeks later by a dose of A before RC. The primary end point was non-muscle-invasive downstaging to < pT2N0.ResultsOf 44 enrolled patients, 39 were evaluable. The primary end point was met, with 27 of 39 patients (69%) < pT2N0, including 16 (41%) pT0N0. No patient with < pT2N0 relapsed and four (11%) with ≥ pT2N0 relapsed with a median follow-up of 16.5 months (range: 7.0-33.7 months). One patient refused RC and two developed metastatic disease before RC; all were considered nonresponders. The most common grade 3-4 adverse event (AE) was neutropenia (n = 16; 36%). Grade 3 immune-related AEs occurred in five (11%) patients with two (5%) requiring systemic steroids. The median time from last dose of chemotherapy to surgery was 7.8 weeks (range: 5.1-17 weeks), and no patient failed to undergo RC because of AEs. Four of 39 (10%) patients had programmed death-ligand 1 (PD-L1)-positive tumors and were all < pT2N0. Of the patients with PD-L1 low or negative tumors, 23 of 34 (68%) achieved < pT2N0 and 11 of 34 (32%) were ≥ pT2N0 (P = .3 for association between PD-L1 and < pT2N0).ConclusionNeoadjuvant GC plus A is a promising regimen for MIBC and warrants further study. Patients with < pT2N0 experienced improved relapse-free survival. The PD-L1 positivity rate was low compared with published data, which limits conclusions regarding PD-L1 as a predictive biomarker.
