ASCEND: Phase III, Randomized Trial of Acalabrutinib Versus Idelalisib Plus Rituximab or Bendamustine Plus Rituximab in Relapsed or Refractory Chronic Lymphocytic Leukemia

PURPOSE Acalabrutinib, a highly selective, potent, Bruton tyrosine kinase inhibitor, was evaluated in this global, multicenter, randomized, open-label, phase III study in patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). METHODS Eligible patients, aged ≥ 18 years with R/R CLL, were randomly assigned 1:1 centrally and stratified by del(17p) status, Eastern Cooperative Oncology Group performance status score, and number of prior lines of therapy. Patients received acalabrutinib monotherapy or investigator’s choice (idelalisib plus rituximab [I-R] or bendamustine plus rituximab [B-R]). The primary end point was progression-free survival (PFS) assessed by an independent review committee (IRC) in the intent-to-treat population. Key secondary end points included IRC-assessed overall response rate, overall survival, and safety. RESULTS From February 21, 2017, to January 17, 2018, a total of 398 patients were assessed for eligibility; 310 patients were randomly assigned to acalabrutinib monotherapy (n = 155) or investigator’s choice (n = 155; I-R, n = 119; B-R, n = 36). Patients had received a median of two prior therapies (range, 1-10). After a median follow-up of 16.1 months (range, 0.03-22.4 months), median PFS was significantly longer with acalabrutinib monotherapy (PFS not reached) compared with investigator’s choice (16.5 months [95% CI, 14.0 to 17.1 months]; hazard ratio, 0.31 [95% CI, 0.20 to 0.49]; P < .0001). Estimated 12-month PFS was 88% (95% CI, 81% to 92%) for acalabrutinib and 68% (95% CI, 59% to 75%) for investigator’s choice. Serious adverse events occurred in 29% of patients (n = 44 of 154) treated with acalabrutinib monotherapy, 56% (n = 66 of 118) with I-R, and 26% (n = 9 of 35) with B-R. Deaths occurred in 10% (n = 15 of 154), 11% (n = 13 of 118), and 14% (n = 5 of 35) of patients receiving acalabrutinib monotherapy, I-R, and B-R, respectively. CONCLUSION Acalabrutinib significantly improved PFS compared with I-R or B-R and has an acceptable safety profile in patients with R/R CLL.

Primary Tumors

TPS477 Background: In pts with LAPC, more effective systemic therapies may be associated with improved local control, delay of metastasis, and overall survival (OS). The phase III MPACT trial in pts with metastatic PC demonstrated longer OS (median, 8.7 vs 6.6 mos; HR, 0.72; P < 0.001) and an ≈ 3-fold greater shrinkage of primary tumors with nab-P + Gem vs Gem alone (−22.15% vs −7.02%), raising the possibility of improved local PC control with nab-P + Gem. LAPACT will assess the efficacy and safety of nab-P + Gem in LAPC. Methods: LAPACT will enroll treatment-naive pts (planned n ≈ 110) in the United States, Canada, and Europe with Eastern Cooperative Oncology Group performance status ≤ 1, confirmed unresectable LAPC, no distant metastases, and adequate organ function. Pts with mixed-origin tumors, any other malignancy within 5 years, peripheral neuropathy grade > 1, or clinically significant ascites are ineligible. Pts will receive nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 of each 28-day cycle. Pts without progressive disease (PD) or unacceptable toxicity after 6 cycles will receive investigator’s choice of surgery, chemoradiotherapy, or continued nab-P + Gem. If a major response is observed, surgery may occur prior to completing 6 cycles of nab-P + Gem. The primary endpoint is time to treatment failure (TTF; time from first therapy dose to discontinuation due to PD, start of a new non–protocol-defined anti-cancer therapy, or death). The study design allows for 80% power at a 1-sided α of 0.05 to detect a 30% increase over the 5.1-month median TTF observed for nab-P + Gem in the MPACT study. The secondary endpoints are disease control rate (DCR) after 6 cycles, overall response rate, progression-free survival, OS, safety, and quality of life. The exploratory endpoint is correlation of changes in circulating nucleic acids with PD and treatment response. An interim DCR analysis will occur after all pts have completed 6 cycles of nab-P + Gem, discontinued therapy due to PD, died, or started a new non–protocol-defined therapy before completing 6 cycles of therapy. Enrollment is ongoing (first pt enrolled in April 2015). Clinical trial information: NCT02301143.

Phase Iii Study

Purpose A phase III study comparing eribulin with dacarbazine in patients with advanced liposarcoma (LPS) or leiomyosarcoma showed a significant improvement in overall survival (OS) for the eribulin arm, with a manageable toxicity profile. We now report the histology-specific subgroup analysis of the efficacy and safety of eribulin compared with dacarbazine in patients with LPS, an independently randomized stratified subgroup of this phase III trial. Methods Patients ≥ 18 years with advanced or metastatic dedifferentiated, myxoid/round cell, or pleomorphic LPS incurable by surgery or radiotherapy were included. Patients with Eastern Cooperative Oncology Group performance status ≤ 2 and two or more prior systemic treatment regimens, including one with anthracycline, were randomly assigned 1:1 to receive eribulin mesylate (1.4 mg/m2 intravenously on days 1 and 8) or dacarbazine (850, 1,000, or 1,200 mg/m2 intravenously on day 1) every 21 days. OS, progression-free survival (PFS), and safety were analyzed. Results In the LPS subgroup, OS was significantly improved: 15.6 versus 8.4 months (hazard ratio, 0.51; 95% CI, 0.35 to 0.75; P < .001) with eribulin versus dacarbazine, respectively. Longer OS with eribulin was observed in all LPS histologic subtypes and in all geographic regions evaluated. PFS was also improved with eribulin versus dacarbazine (2.9 v 1.7 months, respectively; hazard ratio, 0.52; 95% CI, 0.35 to 0.78; P = .0015). Adverse events were similar between arms. Conclusion In patients with previously treated LPS, eribulin was associated with significantly superior OS and PFS compared with dacarbazine. Eribulin represents an important treatment option for patients with LPS, a sarcoma subtype for which limited effective systemic treatments are available. Further studies are justified to explore the role of eribulin in earlier lines of therapy as well as in combination with other agents.

Corticosteroid Dose

BackgroundNo treatment demonstrated to improve survival in patients with recurrent glioblastoma (rGB) in a randomized trial. Combining axitinib with the programmed cell death ligand 1 blocking monoclonal antibody avelumab may result in synergistic activity against rGB.MethodsAdult patients with rGB following prior surgery, radiation therapy and temozolomide chemotherapy were stratified according to their baseline use of corticosteroids. Patients with a daily dose of ≤8 mg of methylprednisolone (or equivalent) initiated treatment with axitinib (5 mg oral two times per day) plus avelumab (10 mg/kg intravenous every 2 weeks) (Cohort-1). Patients with a higher baseline corticosteroid dose initiated axitinib monotherapy; avelumab was added after 6 weeks of therapy if the corticosteroid dose could be tapered to ≤8 mg of methylprednisolone (Cohort-2). Progression-free survival at 6 months (6-m-PFS%), per immunotherapy response assessment for neuro-oncology criteria, served as the primary endpoint.ResultsBetween June 2017 and August 2018, 54 patients (27 per cohort) were enrolled and initiated study treatment (median age: 55 years; 63% male; 91% Eastern Cooperative Oncology Group Performance Status 0–1). Seventeen (63%) patients treated in Cohort-2 received at least one dose of avelumab. The 6-m-PFS% was 22.2% (95% CI 6.5% to 37.9%) and 18.5% (95% CI 3.8% to 33.2%) in Cohort-1 and Cohort-2, respectively; median overall survival was 26.6 weeks (95% CI 20.8 to 32.4) in Cohort-1 and 18.0 weeks (95% CI 12.5 to 23.5) in Cohort-2. The best objective response rate was 33.3% and 22.2% in Cohort-1 and Cohort-2, respectively, with a median duration of response of 17.9 and 19.0 weeks. The most frequent treatment-related adverse events were dysphonia (67%), lymphopenia (50%), arterial hypertension and diarrhea (both 48%). There were no grade 5 adverse events.ConclusionThe combination of avelumab plus axitinib has an acceptable toxicity profile but did not meet the prespecified threshold for activity justifying further investigation of this treatment in an unselected population of patients with rGB.

Palb2 Mutation

PURPOSE Five percent to 9% of pancreatic ductal adenocarcinomas (PDACs) develop in patients with a germline BRCA1/2 or PALB2 (g BRCA/PALB2+) mutation. Phase IB data from a trial that used cisplatin, gemcitabine, and veliparib treatment demonstrated a high response rate (RR), disease control rate (DCR), and overall survival (OS) in this population. We designed an open-label, randomized, multicenter, two-arm phase II trial to investigate cisplatin and gemcitabine with or without veliparib in g BRCA/PALB2+ PDAC. PATIENTS AND METHODS Eligible patients had untreated g BRCA/PALB2+ PDAC with measurable stage III to IV disease and Eastern Cooperative Oncology Group performance status of 0 to 1. Treatment for patients in arm A consisted of cisplatin 25 mg/m2 and gemcitabine 600 mg/m2 intravenously on days 3 and 10; treatment for patients in arm B was the same as that for patients in arm A, and arm A also received veliparib 80 mg orally twice per day on days 1 to 12 cycled every 3 weeks. The primary end point was RRs of arm A and arm B evaluated separately using a Simon two-stage design. Secondary end points were progression-free survival, DCR, OS, safety, and correlative analyses. RESULTS Fifty patients were evaluated by modified intention-to-treat analysis. The RR for arm A was 74.1% and 65.2% for arm B ( P = .55); both arms exceeded the prespecified activity threshold. DCR was 100% for arm A and 78.3% for arm B ( P = .02). Median progression-free survival was 10.1 months for arm A (95% CI, 6.7 to 11.5 months) and 9.7 months for arm B (95% CI, 4.2 to 13.6 months; P = .73). Median OS for arm A was 15.5 months (95% CI, 12.2 to 24.3 months) and 16.4 months for arm B (95% CI, 11.7 to 23.4 months; P = .6). Two-year OS rate for the entire cohort was 30.6% (95% CI, 17.8% to 44.4%), and 3-year OS rate was 17.8% (95% CI, 8.1% to 30.7%). Grade 3 to 4 hematologic toxicities for arm A versus arm B were 13 (48%) versus seven (30%) for neutropenia, 15 (55%) versus two (9%) for thrombocytopenia, and 14 (52%) versus eight (35%) for anemia. CONCLUSION Cisplatin and gemcitabine is an effective regimen in advanced g BRCA/PALB2+ PDAC. Concurrent veliparib did not improve RR. These data establish cisplatin and gemcitabine as a standard approach in g BRCA/ PALB2+ PDAC.

Abstract Background: Addition of erlotinib to metronomic chemotherapy (MCT) may lead to further improvement in progression-free survival (PFS) and overall survival in head and neck cancers. The aim of this study was to study the PFS with MCT + erlotinib combination in our setting. Methods: A single-arm prospective observational study conducted at Malabar Cancer Center. Patients warranting palliative chemotherapy for head and neck cancers, having adequate organ function, not-affording cetuximab and not willing for intravenous chemotherapy were included in this study. Oral methotrexate (15 mg/m 2 /week), oral celecoxib (200 mg twice daily), and erlotinib (150 mg once daily) were administered till the progression of the disease or till intolerable side-effects. Patients underwent toxicity (CTCAE version 4.02) and response (RECIST version 1.1) assessment every 30 days. Statistical analysis was performed using SPSS version 16 (IBM, New York, USA). Descriptive statistics and Kaplan-Meier analysis have been performed. Results: A total of 15 patients received MCT. The median age of these patients was 65 years (range: 48-80). The Eastern Cooperative Oncology Group Performance Status was 0-1 in seven patients (46.7%), while it was 2 in eight patients (53.3%). The primary sites of tumor were predominantly oral cavity, 11 (73.4%). Prior to MCT, treatment with palliative radiation therapy was given in 11 patients and curative treatment in two patients. The best response post-MCT was complete remission in two patients, partial remission in seven patients, stable disease in four patients, and progressive disease in two patients. The median estimated PFS was 148 days (95% confidence interval 95.47-200.52 days). For a median follow-up of 181 days, there were only three deaths. Grade 3-4 toxicity was seen in six patients (40%). Dose reduction was required in four patients (26.7%). Conclusion: The addition of erlotinib to an MCT schedule of methotrexate and celecoxib resulted in a promising PFS and should be tested in future studies.

BackgroundIn RECOURSE (, trifluridine/tipiracil significantly improved overall survival and progression-free survival (PFS) versus placebo in patients with pretreated metastatic colorectal cancer (mCRC). PRECONNECT was designed to further characterise safety and clinical use of trifluridine/tipiracil.MethodsIn this ongoing, international, multicentre, open-label trial, patients with pretreated mCRC received oral trifluridine/tipiracil 35 mg/m2 twice daily on days 1–5 and 8–12 of each 28-day cycle. The primary endpoint was safety; secondary endpoints included PFS and quality of life (QoL).Results793 patients (median age 62 years) from 13 countries received trifluridine/tipiracil for a median of 2.84 months (IQR 2.64). Adverse events (AEs) were experienced by 96.7%; the most common (≥20% of patients) were neutropaenia, asthenia/fatigue, nausea, anaemia and diarrhoea. Grade ≥3 AEs occurred in 73.9% of patients, with the most common being neutropaenia (39.1% of patients), anaemia (9.8%) and asthenia/fatigue (5.0%). Median PFS was 2.8 months (95% CI 2.7 to 2.9). Median time to Eastern Cooperative Oncology Group performance status deterioration (≥2) was 8.9 months (range 0.03–14.72). There was no clinically relevant change from baseline in QoL.ConclusionsPRECONNECT showed consistent results with the previously demonstrated safety and efficacy profile of trifluridine/tipiracil, with no new safety concerns identified. QoL was maintained during treatment.Trial registration numberNCT03306394.

Purpose Symptoms and complications of metastatic colorectal cancer (mCRC) differ by metastatic sites. There is a paucity of prospective survival data for patients with peritoneal carcinomatosis colorectal cancer (pcCRC). We characterized outcomes of patients with pcCRC enrolled onto two prospective randomized trials of chemotherapy and contrasted that with other manifestations of mCRC (non-pcCRC). Methods A total of 2,095 patients enrolled onto two prospective randomized trials were evaluated for overall survival (OS) and progression-free survival (PFS). A Cox proportional hazard model was used to assess the adjusted associations. Results The characteristics of the pcCRC group (n = 364) were similar to those of the non-pcCRC patients in median age (63 v 61 years, P = .23), sex (57% males v 61%, P = .23), and performance status (Eastern Cooperative Oncology Group performance status 0 or 1 94% v 96%, P = .06), but differed in frequency of liver (63% v 82%, P < .001) and lung metastases (27% v 34%, P = .01). Median OS (12.7 v 17.6 months, hazard ratio [HR] = 1.3; 95% CI, 1.2 to 1.5; P < .001) and PFS (5.8 v 7.2 months, HR = 1.2; 95% CI, 1.1 to 1.3; P = .001) were shorter for pcCRC versus non-pcCRC. The unfavorable prognostic influence of pcCRC remained after adjusting for age, PS, liver metastases, and other factors (OS: HR = 1.3, P < .001; PFS: HR = 1.1, P = .02). Infusional fluorouracil, leucovorin, and oxaliplatin was superior to irinotecan, leucovorin, and fluorouracil as a first-line treatment among pcCRC (HR for OS = 0.62, P = .005) and non-pcCRC patients (HR = 0.66, P < .001). Conclusion pcCRC is associated with a significantly shorter OS and PFS as compared with other manifestations of mCRC. Future trials for mCRC should consider stratifying on the basis of pcCRC status.

7035 Background: CAM307 is a phase III, open-label, randomized controlled trial comparing alemtuzumab (CAM) with chlorambucil (CHLO) for previously untreated B-CLL. Methods: The trial enrolled 297 previously untreated patients requiring therapy according to NCI-WG criteria. Patients were randomized 1:1 to CAM (n=149) vs CHLO (n=148) using standard dosing regimens. Diagnosis, Rai stage, response and disease progression were confirmed by an independent response review panel. In the overall study population, CAM demonstrated significantly higher overall response rates (ORR) than CHLO (83 % vs 55%) and a significant improvement in PFS (p= 0.0001) with manageable toxicities1. Outcomes according to Rai stage and cytogenetics have been previously reported.1,2 A pre-specified subgroup analysis of response rates (RR) and progression-free survival (PFS) by prognostic factors was performed. Results: Additional analyses revealed statistically significant PFS advantage in favor for CAM vs. CHLO for patients with β-2 microglobulin =3 mg/L (p<0.0001) or marrow infiltration =90% (p=0.0001). Conclusions: CAM is significantly superior to CHLO relative to overall and complete RR and PFS in the overall study population of previously untreated patients with CLL, and in patients < 65 years of age, < 70 years of age, maximum lymph node size < 5cm, and, performance status <2. Campath deserves further study in patients with age = 70, patients with massive lymphadenopathy, and in those with poor performance status. 1. Hillmen, P et al, Blood 108(11), abstract 301 2.

3573 Background: The phase III VELOUR study demonstrated that adding the novel antiangiogenic agent ziv-aflibercept (known as aflibercept outside the United States) to FOLFIRI in patients with metastatic colorectal cancer previously treated with oxaliplatin significantly improved overall survival, progression-free survival (PFS), and overall response rate vs placebo/FOLFIRI. We performed an additional analysis of PFS “on-treatment,” censoring events that occurred more than 28 days after last treatment dose. Methods: Patients were randomized to receive ziv-aflibercept 4 mg/kg or placebo every 2 weeks in combination with FOLFIRI. An independent review committee determined progression based on radiologic review. PFS was estimated using Kaplan-Meier analysis, with censoring of events after the last dose plus 28 days. Treatment groups were compared using a log-rank test and were stratified by Eastern Cooperative Oncology Group performance status and prior bevacizumab therapy. Hazard ratio (HR) and confidence interval (CI) were estimated using a Cox proportional hazard model. Results: On-treatment analysis showed significantly increased PFS for patients treated with ziv-aflibercept/FOLFIRI compared with placebo/FOLFIRI (Table). More patients were censored in the ziv-aflibercept arm due to adverse events. Conclusions: The on-treatment PFS analysis demonstrates a significantly improved treatment effect of the addition of ziv-aflibercept to FOLFIRI (HR=0.55) over what was observed in the primary analysis suggesting that continuing treatment with ziv-aflibercept up to disease progression provides additional benefit. Clinical trial information: NCT00561470. [Table: see text]

CAM307 is a phase III, open-label, multinational, randomized controlled trial comparing alemtuzumab (CAM) with chlorambucil (CHLO) for previously untreated BCLL requiring therapy. Eligible patients with Rai Stages I–IV were randomized 1:1 to either CAM 30 mg IV tiw for up to 12 weeks or CHLO 40 mg/m2 po q 28 days up to 12 cycles. CAM patients received prophylactic trimethoprim/sulfamethoxazole DS and famciclovir treatment during therapy and until CD4+ counts were ≥200 cells/μL. The primary endpoint was PFS; secondary endpoints were response rate, overall survival, and safety. A total of 297 patients were enrolled (CAM n=149 and CHLO n=148); median age: 60 years; performance status 0–1: 96%; maximum lymph node size ≥5 cm: 22%; and Rai Stage I–II: 63%, Rai Stage III–IV: 33%. Diagnosis, Rai Stage, response and disease progression were confirmed by an independent response review panel (IRRP). CAM has a significantly prolonged PFS compared to CHLO (p=0.0001; see KM survival curve).PFS in CAM vs CHLO patients with adverse cytogenetic findings of del 17p (n=21) was 10.7 mo vs 2.2 mo and for trisomy 12 (n=39) was 18.3 mo vs 12.9 mo. Results were similar for patients with del 11q (n=54, 8.5 mo vs 8.6 mo). Common (≥15%) CAM reported adverse events (AEs) (n=147), likely infusion-related, included pyrexia (70%), chills (53%), nausea (18%), hypotension (16%) and urticaria (16%). Common AEs (≥15%) in the CHLO arm (n=147) were nausea (37%) and vomiting (18%). Frequency of asymptomatic CMV viremia on the CAM arm was 52%; CMV infection occurred in only 16%, none grade 4. CAM treatment was interrupted in 56% of CMV viremic patients, and resumed in 92% with ORR 92% (31% CR). Ganciclovir was administered to 41% of CAM patients with CMV viremia. Infections, including CMV, were reported in 76% of CAM and 50% of CHLO patients while on study. Relevant grade 3/4 treatment-emergent events included (CAM vs CHLO): lymphopenia (97% vs 3%), pyrexia (8% vs 0%), CMV events (8% vs 0%) and chills (3% vs 0%). Treatment emergent grade 3/4 thrombocytopenia (16% vs 13%) and anemia (14% vs 19%) were similar, and although grade 3/4 neutropenia was more common with CAM, (45% vs. 26%), AEs of CAM vs CHLO bacteremia/sepsis (3% vs 2%) and febrile neutropenia (5% vs 3%) were comparable. Serious AEs were reported for 44% of CAM (20% for IV Ganciclovir only in CMV viremic patients) and 20% of CHLO patients while on study treatment. CONCLUSIONS: CAM307 demonstrates that therapy-naïve BCLL patients treated with CAM have significantly longer PFS and higher ORR than those treated with CHLO, with manageable toxicities. Although CMV reactivation was reported in the CAM arm, prompt intervention maintained efficacy. The activity seen here supports ongoing investigations of CAM in first line combination therapy, high risk patients and consolidation. Figure Figure
