Improvements in Survival and Clinical Benefit With Gemcitabine as First-Line Therapy for Patients With Advanced Pancreas Cancer: A Randomized Trial.

Most patients with advanced pancreas cancer experience pain and must limit their daily activities because of tumor-related symptoms. To date, no treatment has had a significant impact on the disease. In early studies with gemcitabine, patients with pancreas cancer experienced an improvement in disease-related symptoms. Based on those findings, a definitive trial was performed to assess the effectiveness of gemcitabine in patients with newly diagnosed advanced pancreas cancer. One hundred twenty-six patients with advanced symptomatic pancreas cancer completed a lead-in period to characterize and stabilize pain and were randomized to receive either gemcitabine 1,000 mg/m2 weekly x 7 followed by 1 week of rest, then weekly x 3 every 4 weeks thereafter (63 patients), or to fluorouracil (5-FU) 600 mg/m2 once weekly (63 patients). The primary efficacy measure was clinical benefit response, which was a composite of measurements of pain (analgesic consumption and pain intensity), Karnofsky performance status, and weight. Clinical benefit required a sustained (> or = 4 weeks) improvement in at least one parameter without worsening in any others. Other measures of efficacy included response rate, time to progressive disease, and survival. Clinical benefit response was experienced by 23.8% of gemcitabine-treated patients compared with 4.8% of 5-FU-treated patients (P = .0022). The median survival durations were 5.65 and 4.41 months for gemcitabine-treated and 5-FU-treated patients, respectively (P = .0025). The survival rate at 12 months was 18% for gemcitabine patients and 2% for 5-FU patients. Treatment was well tolerated. This study demonstrates that gemcitabine is more effective than 5-FU in alleviation of some disease-related symptoms in patients with advanced, symptomatic pancreas cancer. Gemcitabine also confers a modest survival advantage over treatment with 5-FU.

Pilot Study of High-Dose Pemetrexed in Patients with Progressive Chordoma.

Chordomas are ultrarare tumors of the axial spine and skull-base without approved systemic therapy. Most chordomas have negative expression of thymidylate synthase (TS), suggesting a potential for responding to the antifolate agent pemetrexed, which inhibits TS and other enzymes involved in nucleotide biosynthesis. We evaluated the therapeutic activity and safety of high-dose pemetrexed in progressive chordoma. Adult patients with previously treated, progressive chordoma participated in an open-label, single-institution, single-arm, pilot clinical trial of intravenous pemetrexed 900 mg/m2 every 3 weeks and supportive medications of folic acid, vitamin B12, and dexamethasone. The primary endpoint was objective response rate according to RECIST v1.1. Secondary endpoints included adverse events, progression-free survival (PFS), tumor molecular profiles, and alterations in tissue and blood-based biomarkers. Fifteen patients were enrolled and the median number of doses administered was 15 (range, 4-31). One patient discontinued treatment due to psychosocial issues after four cycles and one contracted COVID-19 after 13 cycles. Of the 14 response-evaluable patients, 2 (14%) achieved a partial response and 10 (71%) demonstrated stable disease. Median PFS was 10.5 months (95% confidence interval: 9 months-undetermined) and 6-month PFS was 67%. Adverse events were expected and relatively mild, with one grade 3 creatinine increased, and one each of grade 3 and 4 lymphopenia. No grade 5 adverse events, unexpected toxicities, or dose-limiting toxicities were observed. Several patients reported clinical improvement in disease-related symptoms. High-dose pemetrexed appears tolerable and shows objective antitumor activity in patients with chordoma. Phase II studies of high-dose pemetrexed are warranted.

CTNI-15. PILOT STUDY OF HIGH-DOSE PEMETREXED FOR PROGRESSIVE CHORDOMA

Abstract INTRODUCTION Chordomas are ultra-rare tumors of the spine, and no systemic therapy is approved for refractory disease. Pemetrexed is a multitargeted antifolate that inhibits thymidylate synthase (TS) and other enzymes involved in nucleotide biosynthesis. Considering the majority of chordomas do not express TS, we sought to evaluate the therapeutic activity and safety of high-dose pemetrexed. METHODS Adults with previously-treated chordoma were enrolled on an open-label, single-institution, single-arm, pilot clinical trial. Pemetrexed 900 mg/m2 was administered intravenously every 3 weeks, with supportive medications of folic acid, vitamin B12, and dexamethasone. The primary endpoint was objective response rate according to RECIST v1.1. Secondary and exploratory endpoints included adverse events, progression-free survival (PFS), tumor molecular profiles, and alterations in potential tissue and blood-based biomarkers before and after treatment. RESULTS Fifteen patients with chordoma received a median of 15 (range 4-31) doses of pemetrexed. Median PFS was 10.5 months (95% CI 9 months-undetermined) and 6-month PFS was 67%. Out of 14 response-evaluable patients, two (14%) achieved a partial response and ten (71%) demonstrated stable disease. Adverse events were generally mild at grades 1-2, the most common being fatigue, rash, nausea, constipation, diarrhea, mucositis, vomiting, alopecia, pruritus, lower extremity edema, and alanine transaminase increased. One Grade 3 creatinine increase, one Grade 3 lymphopenia, and one Grade 4 lymphopenia occurred and there were no Grade 5 adverse events, unexpected toxicities, or dose-limiting toxicities. Clinical improvement in disease-related symptoms occurred in several patients. Tumor molecular profiling revealed low mutational burden and though not statistically significant, positive TS expression trended negatively with disease progression. Cell-free microRNAs (cfmiRs) were concordantly detected in plasma and tissues and a blood cfmiR signature was identified that distinguished chordoma from health donors. CONCLUSION High-dose pemetrexed is safe and well-tolerated in chordoma patients. A phase II study is in development. (NCT03955042)

JS01.5.A PHASE 2 TRIAL OF CARBOPLATIN AND BEVACIZUMAB FOR RECURRENT ADULT EPENDYMOMA. A CERN STUDY

Abstract BACKGROUND Most adults with ependymoma undergo tumor resection at the time of diagnosis, which may be followed by radiation. At recurrence, re-resection and/or (re)-irradiation may be given, however, there are few established chemotherapy treatments. A previous retrospective report of 8 patients treated with carboplatin and bevacizumab showed a high response rate with 6 patients demonstrating an imaging response (Green, Neurology 2009). We sought to further investigate this regimen with a prospective trial. MATERIAL AND METHODS We performed a prospective phase 2 study in the CERN Adult Clinical Trials Network. Adult patients with recurrent or progressive ependymoma were enrolled to receive carboplatin (AUC =4-5) every 4 weeks for up to 6 cycles and bevacizumab at 10mg/kg every 2 weeks for one year, with the option to continue until progression or toxicity. The primary endpoint was 12-month PFS rate and >50% defined efficacy. Serial symptom burden measurement at baseline and at the time of disease evaluation using MD Anderson Symptom Inventory-brain tumor (MDASI-BT) or MDASI-Spine patient-reported outcomes (PROs) were used to evaluate the clinical impact of PFS. RESULTS A total of 22 patients with median age of 45 years were accrued and treated; 11 were women. WHO grade was 3 in 13 patients and grade 2 in 9 patients (3 with myxopapillary ependymoma) Ten patients had only spinal cord disease, 3 had both spinal cord and brain involvement and 9 patients had brain involvement alone (6 supratentorial, 3 infratentorial). Previous treatments included radiotherapy in all 22 patients and alkylating chemotherapy in 9 patients. Treatment was well tolerated with expected myelotoxicities and hypertension. The Kaplan-Meier calculated 12-Month PFS rate was 76.4% (95%CI 52.2%, 89.4%), median PFS = 18 months (95%CI 12.2, +∞). There were 2 partial responses (9.1%). Brain tumor responders (objective response or stable disease) showed reduction while non-responders had an increase in both neurologic and cognitive symptoms but similar report of other symptoms. Spine tumor responders and non-responders both showed worsening disease-related symptoms; autonomic symptoms worsened in responders. Activity related interference worsened for all patients. CONCLUSION This treatment regimen was safe and met the primary efficacy endpoint of 12-month PFS rate. The improvement in disease-related symptoms in brain tumor patients supports that the achieved disease stability was clinically meaningful, but the increased activity-related interference suggests that treatment-associated symptoms may impact work, general activity, and walking ability during treatment. Improvements in spine tumor disease-associated symptoms were not seen. A confirmatory trial is warranted to further investigate the findings and to determine if there are differences in response amongst ependymoma subtypes and tumor location.

Exploring the Barriers and Enablers to Implementing a 16-Week Low-Carbohydrate Diet for Patients With Diabetic Cardiomyopathy.

Cardiac dysfunction in patients with diabetes, referred to as diabetic cardiomyopathy, is primarily precipitated by dysregulations in glucose and lipid metabolism. Diet and lifestyle changes are considered crucial for successful heart failure and diabetes management and are often difficult to achieve. Low-carbohydrate diets (LCDs) have gained popularity for the management of metabolic diseases. Although quantitative research in this field is evolving, little is known about the personal experience of patients with diabetic cardiomyopathy on specific diets. The aim of this qualitative study was to identify enablers and barriers of patients with diabetic cardiomyopathy who engage in an LCD. It further explored patients' perception of dietary education and dietary support received while in hospital. Participants who previously consented to a 16-week LCD trial were invited to share their experiences. Nine patients agreed to be interviewed. Semistructured interviews and a focus group interview were conducted, which were transcribed verbatim. Data were analyzed by using the 6-step approach for thematic analysis. Four themes were identified: (1) nutrition literacy (2) disease-related health benefits, (3) balancing commitments, and (4) availability of resources and support. Improvements in disease-related symptoms acted as strong enablers to engage in an LCD. Barriers such as access to resources and time constraints were identified. These challenges may be overcome with efficient communication and ongoing dietary support. More research exploring the experience of patients with diabetic cardiomyopathy on an LCD are warranted.

The Impact of Momelotinib on Patient Reported Quality of Life for Symptomatic and Anemic Patients with Myelofibrosis: Results from the Phase 3 Momentum Study

Introduction Disease-related inflammation, anemia and splenomegaly contribute to a host of burdensome symptoms in patients with myelofibrosis (MF), including fatigue, bone pain, night sweats, and others, which can negatively impact health-related quality of life (HRQoL). There are no approved treatments for patients with intermediate- and high-risk MF that specifically target anemia, and approved MF therapies for splenomegaly and symptoms often exacerbate anemia. Momelotinib (MMB) is a Janus kinase (JAK) 1, JAK2, and activin A receptor type 1 (ACVR1) inhibitor with demonstrated symptom, spleen, and anemia benefits in patients with MF. MOMENTUM, a phase 3 study in symptomatic, anemic patients with MF who were previously treated with a JAKi, showed that MMB significantly improved disease-related symptoms compared to danazol (DAN) (24.6% vs 9.2%) as measured by achieving at least a 50% reduction in total symptom score (TSS50) at week 24 compared to baseline. Herein we report the results of patient-reported health status and HRQoL analyses, including impact on fatigue and physical function, for patients treated with MMB compared to DAN in the MOMENTUM study. Methods Patient-reported outcome (PRO) analyses were performed for the following assessments in the intent-to-treat (ITT) population: Myelofibrosis Symptom Assessment Form (MFSAF) v4.0 TSS and individual items, European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30)-derived scales and items, and Patient-Reported Outcomes Measurement Information System (PROMIS) short form physical function total score 10b and additional PROMIS bank items. Analyses of PRO response were summarized by corresponding meaningful change threshold (MCT) for each PRO. Longitudinal change from baseline scores were analyzed using mixed model for repeated measures (MMRM). Longitudinal responder analyses were performed by generalized estimating equation (GEE) after multiple imputation for missing scores. Odds ratio (OR) for response, 95% confidence interval (CI), and p-value were presented as the treatment effect (MMB vs DAN). Time to first response was analyzed using the Kaplan-Meier method. A stratified log-rank test was performed to compare treatment arms, and hazard ratios (HR) were estimated from a stratified Cox regression model. Results Proportionally greater improvements in MF-related symptoms, physical function, and global quality of life were observed with MMB versus DAN as measured at week 24 by the MFSAF, PROMIS, and EORTC QLQ-C30 questionnaires, respectively. Improvements in all MFSAF individual item scores from baseline at week 24 were greater in the MMB group than in the DAN group based on median scores (Figure 1) and MMRM analysis (Table 1), with the greatest treatment differences noted for night sweats, abdominal discomfort, bone pain, and rib pain, favoring MMB. Longitudinal MFSAF TSS response analysis indicated a higher likelihood of response for patients in the MMB group: an overall OR of 2.50 throughout the 24-week randomized treatment period. HRs for response were greater than 1 (ranging from 1.47 - 3.82) in the time to first response analysis for MFSAF TSS and individual items, excluding itching (0.77), indicating a faster symptom response for more patients in the MMB group for TSS and 6 of 7 individual items. Responder analyses showed that the proportion improved for fatigue was greater in the MMB group based on MFSAF fatigue (18.5% MMB, 9.2% DAN) and EORTC QLQ-C30 fatigue (41.5% MMB, 21.5% DAN), where missing data was considered nonresponse. Consistent with these results, responder analysis using the PROMIS assessments related to physical function also favored MMB (17.7% MMB, 4.6% DAN). This trend was supported by shorter times to first response for physical function in more patients in the MMB group versus the DAN group (HR = 1.93, 95% CI 0.95, 3.91). Improvement in global quality of life as measured by EORTC QLQ-C30 was also greater in the MMB group with a proportion difference of 14.6% between MMB and DAN (95% CI: 1.5-27.7%; p = 0.04). Conclusions Consistent with the positive primary endpoint (TSS50) result of the MOMENTUM study, these responder, longitudinal, and time-to-event analyses demonstrate that MMB provides comprehensive improvements in disease-related symptoms with associated improvement in physical function and overall HRQoL compared with DAN in patients with MF.

Tubal Endometriosis: From Bench to Bedside, A Scoping Review.

Tubal endometriosis (EM) refers to the detection of ectopic endometrial implants on tubes. It may cause a significant defect of the tubes, translating into dysmenorrhea, pelvic pain, and infertility. We aimed to evaluate the disease characteristics, prevalence, histopathological findings and genetic profile of patients with tubal EM. A thorough search of three electronic databases was performed for studies that presented outcomes of patients with tubal EM. Thirteen studies (four observational, seven case reports, two genetic) were considered eligible for inclusion. The prevalence of tubal EM ranged from 6.9% to 69%. The predominant symptoms for referral of patients were infertility and abdominal pain. Women of reproductive age underwent salpingectomy for the management of the disease. Only one case of malignant transformation was recorded in a 60-year-old patient. The prevalence of tubal EM ranges depending on the indication for surgery, the presence of concomitant pelvic EM and the type of diagnosis and treatment. Further, more extensive, larger studies are warranted to evaluate the impact of tubal EM in the progression and prognosis of EM, the effect of salpingectomy in the improvement of disease-related symptoms and to designate the group of patients that could benefit from risk-reducing salpingectomy based on the risk of developing ovarian malignancy.

Three-year follow-up and patient-reported outcomes from CheckMate 078: Nivolumab versus docetaxel in a predominantly Chinese patient population with previously treated advanced non-small cell lung cancer

ObjectivesIn the phase 3 CheckMate 078 study, nivolumab prolonged overall survival (OS) and showed a favorable safety profile versus docetaxel in a predominantly Chinese patient population with previously treated advanced non-small cell lung cancer (aNSCLC). However, long-term efficacy, safety, and health-related quality of life findings with second-line nivolumab are very limited in Asian patients with previously treated aNSCLC. Here, we report updated clinical data and patient-reported outcomes (PROs) from the phase 3 CheckMate 078 trial with a 3-year minimum follow-up. Materials and methodsPatients with aNSCLC and disease progression after platinum-doublet chemotherapy were randomized 2:1 to nivolumab (3 mg/kg every 2 weeks) or docetaxel (75 mg/m2 every 3 weeks) until progression or unacceptable toxicity. The primary endpoint was OS; secondary endpoints included objective response rate, progression-free survival, safety, and disease-related symptom deterioration assessed using the Lung Cancer Symptom Scale (LCSS) by Week 12. Additional PRO assessments were exploratory endpoints. ResultsAt ≥ 37.3 months follow-up, 3-year OS rates were 19% with nivolumab and 12% with docetaxel; 30% and 0% of responders remained in response for ≥ 3 years, respectively. Incidence of treatment-related adverse events occurring after 2 years was lower than during the first 2 years. No new treatment-related deaths were reported. By Week 12 of treatment, rates of disease-related symptom deterioration were 32% with nivolumab and 47% with docetaxel. Completion rates for PRO questionnaires were ≥ 80% in both arms. Clinically meaningful and sustained improvements in LCSS Average Symptom Burden Index scores and delayed time to first symptom deterioration were observed with nivolumab against docetaxel. ConclusionsAt 3 years, nivolumab continued to demonstrate survival benefit versus docetaxel, exhibiting improvements in disease-related symptoms and overall health status in a predominantly Chinese patient population with previously treated aNSCLC. No new safety signals were observed. These findings are similar to the global population.

Patient-Reported Outcomes in Patients with Classical Hodgkin Lymphoma Treated with Pembrolizumab Monotherapy, Results of a Phase 2 Study

Patient-Reported Outcomes in Patients with Classical Hodgkin Lymphoma Treated with Pembrolizumab Monotherapy, Results of a Phase 2 Study

Phase I study of pasotuxizumab (AMG 212/BAY 2010112), a PSMA-targeting BiTE (Bispecific T-cell Engager) immune therapy for metastatic castration-resistant prostate cancer (mCRPC).

124 Background: mCRPC has a poor prognosis and immunotherapies are largely ineffective. PSMA is a promising therapeutic target in mCRPC. Pasotuxizumab is a PSMA x CD3 BiTE immune therapy that mediates killing of tumor cells by T cells. Methods: NCT01723475 was a first-in-human, multicenter, dose-escalation study in patients (pts) with mCRPC refractory to standard therapy. Pts received continuous IV infusion of pasotuxizumab in cohorts of 3–4 pts. Dose-escalation followed a continuous reassessment methodology. The primary objective was to determine safety and maximum tolerated dose (MTD); secondary objectives included pharmacokinetics, biomarkers, and tumor response. Results: 16 pts were enrolled into 5 dosing cohorts (5 µg/d, n=3; 10 µg/d, n=4; 20 µg/d, n=3; 40 µg/d, n=4; 80 µg/d, n=2). All pts had ≥1 AE of any grade; most common were fever (94%), chills (69%), and fatigue (50%). 13 pts (81%) had ≥1 AE of grade ≥3; most common were decreased lymphocytes and infections (both 44%). No grade 5 AE occurred. A serious drug-related AE was reported for 1 pt (fatigue, 20 µg/d). No antidrug antibodies were observed. Recruitment was stopped before MTD was reached to allow initiation of a new study sponsored by Amgen. Antitumor activity as indicated by PSA serum level decline was dose dependent, with a mean best PSA change per dosing cohort vs baseline of +0.74% (5 µg/d), −17.9% (10 µg/d), −37.4% (20 µg/d), −42.5% (40 µg/d) and −54.9% (80 µg/d). PSA decreases ≥50% occurred in 3 pts (n=1 each in 20 µg/d, 40 µg/d, 80 µg/d cohorts). One long-term PSA responder was treated for 14 months (40 µg/d) and one for 19.4 months (80 µg/d). The latter pt showed a complete regression of soft-tissue metastases and marked regression of bone metastases by PSMA-PET/CT, >90% reduction in PSA and alkaline phosphatase, and a significant and durable improvement in disease related symptoms. Conclusions: Pasotuxizumab had an acceptable safety profile and dose-dependent clinical activity in mCRPC pts. There were two long term responders in the dose escalation. This is the first clinical study showing that a BiTE immune therapy can be efficacious in solid tumors. Clinical trial information: NCT01723475.

Predictive Impact of Clinical Benefit in Chemotherapy-treated Advanced Pancreatic Cancer Patients in Northern Alberta.

Patients with advanced pancreatic cancer (APC) have a poor prognosis and experience a large burden of disease-related symptoms. Despite advancements in the treatment of APC, survival is dismal and controlling disease-related symptoms and maintaining quality of life is paramount. We hypothesize that an improvement in disease-related symptoms, and therefore, a clinical benefit, while on chemotherapy is a predictive marker in APC. Patients 18 and older with APC diagnosed between January 1, 2005 and December 31, 2010 and treated at the Cross Cancer Institute were identified using the provincial cancer registry. Disease symptoms were assessed at baseline and clinical benefit while on chemotherapy was defined using a composite endpoint of improvement in patient-reported pain, opioid consumption, Eastern Cooperative Oncology Group performance status, and/or weight. Best radiologic response, progression-free survival (PFS), and overall survival (OS) were recorded. Of 103 patients, the median age was 64, 58% were male and 66% had metastatic disease. At baseline, the majority of patients reported pain (80%), opioid use (61%), or weight loss (71%). In total, 35 (34%) patients received a clinical benefit with treatment but only 6 (17%) of these patients experienced a radiologic response. The median PFS and OS were improved in patients who experienced a clinical benefit (6.6 vs. 4.6 mo; P=0.03 and 11.7 vs. 6.1 mo; P<0.0001, respectively). In patients with APC treated with chemotherapy, experiencing a clinical benefit was associated with improved PFS and OS. However, it did not appear to correlate with radiologic response to chemotherapy. Prospective studies are warranted to further investigate the prognostic and predictive value of clinical benefit and improvement in quality of life as measured by standardized tools, in APC.

Evaluation of health-related quality of life and symptoms in patients with advanced non-squamous non-small cell lung cancer treated with nivolumab or docetaxel in CheckMate 057

BackgroundNivolumab, a programmed death-1 inhibitor, prolonged overall survival and had a favourable safety profile versus docetaxel in previously treated patients with advanced non-squamous non-small cell lung cancer (NSCLC) in the phase III CheckMate 057 trial. AimTo evaluate health-related quality of life (HRQoL) using patient-reported outcomes. MethodsDisease-related symptoms and general health status were assessed using two validated patient-reported instruments, the Lung Cancer Symptom Scale (LCSS) and the European Quality of Life Five Dimensions (EQ-5D), respectively. The proportion of patients with disease-related symptom improvement at 12 weeks on the LCSS average symptom burden index (ASBI) was a secondary end-point. LCSS 3-item global index (3-IGI), EQ-5D utility index and EQ-5D visual analogue scale (VAS) scores were also determined. Mixed-effects model repeated measures (MMRM) and time to first deterioration analyses assessed longitudinal changes. ResultsMean baseline LCSS ASBI scores were similar in both arms. By week 12, rates of disease-related improvement (95% confidence interval) were similar between nivolumab (17.8% [13.6–22.7]) and docetaxel (19.7% [15.2–24.7]); however, numerical differences in LCSS ASBI mean change from baseline favoured nivolumab. Subsequently, LCSS ASBI scores improved with nivolumab and worsened with docetaxel, with statistically significant between-arm differences at weeks 12, 24, 30 and 42. HRQoL improvements with nivolumab versus docetaxel were also supported by the LCSS 3-IGI, EQ-5D VAS and MMRM analysis. Time to first HRQoL deterioration was longer with nivolumab than with docetaxel. ConclusionNivolumab improved disease-related symptoms and overall health status versus docetaxel for second-line treatment of advanced non-squamous NSCLC. Clinical trial registrationNCT01673867.

Myeloproliferative Neoplasms, Version 2.2017, NCCN Clinical Practice Guidelines in Oncology.

Myelofibrosis (MF), polycythemia vera (PV), and essential thrombocythemia (ET) are a group of heterogeneous disorders of the hematopoietic system collectively known as Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs). The diagnosis and the management of patients with MPNs have evolved since the identification of mutations that activate the JAK pathway (JAK2, CALR, and MPL mutations) and the development of targeted therapies has resulted in significant improvements in disease-related symptoms and quality of life. This manuscript discusses the recommendations outlined in the NCCN Guidelines for the diagnostic workup of MPN (MF, PV, and ET), risk stratification, treatment, and supportive care strategies for the management of MF.

Abstract CT084: A randomized, double-blind phase III study of phosphatidylinositol-3 kinase alpha/delta inhibitor copanlisib versus placebo in patients with rituximab-refractory indolent non-Hodgkin's lymphoma (iNHL): CHRONOS-2

Abstract Background: Copanlisib is a novel pan-Class I phosphatidylinositol-3-kinase (PI3K) inhibitor with potent preclinical inhibitory activity against both PI3K-δ and PI3K-α isoforms. A phase II study of copanlisib in patients with relapsed/refractory indolent or aggressive lymphoma reported promising activity in the indolent NHL group (Dreyling et al., ENA 2014). The objective of this study is to evaluate the efficacy and safety of copanlisib in patients with indolent B-cell NHL relapsed after or refractory to standard therapy. Methods: Patients meeting the following criteria are eligible for enrollment: histologically confirmed diagnosis of indolent B-cell NHL, with follicular lymphoma (FL) grade 1-2-3a, marginal zone lymphoma (MZL; splenic, nodal, or extra-nodal), small lymphocytic lymphoma (SLL) with absolute lymphocyte count &amp;lt; 5 × 109/L at the time of diagnosis and at study entry, or lymphoplasmacytoid lymphoma/Waldenström macroglobulinemia (LPL/WM), and who have previously received ? 2 prior lines of therapy with rituximab and an alkylating agent and must be refractory to the last treatment with rituximab (refractory defined as progressing or not responding within 6 months of the last course of treatment). Patients will be randomized in 2:1 manner to receive 60 mg of copanlisib administered intravenously on days 1, 8 and 15 of a 28-day cycle or placebo administered on the same schedule until disease progression or intolerable toxicity. Patients in the placebo arm will be allowed to cross-over to receive follow-up treatment with copanlisib, after confirmed disease progression. Dose reductions due to toxicities will be allowed. Radiologic tumor assessment will be performed every 12, 16 or 24 weeks for years 1, 2, and 3, respectively. The primary endpoint will be progression-free survival (PFS). Secondary objectives include overall objective response rate (ORR), duration of response (DOR), time to progression (TTP), complete response rate (CRR), overall survival (OS), time to deterioration as well as time to improvement in disease-related symptoms. Exploratory objectives will include secondary PFS after first progression in placebo-treated patients who cross over to receive copanlisib and time to improvement and the time to deterioration in disease-related symptoms - physical (DRS-P) of at least 3 points as measured by the FLymSI-18 questionnaire. Approximately 189 patients who meet the eligibility criteria will be randomized 2:1, with approximately 126 patients in the copanlisib monotherapy arm and approximately 63 patients in placebo arm. The study is planned to detect a 132% increase in median PFS in copanlisib versus placebo (i.e. to detect a hazard ratio of 0.43), using a stratified log-rank test. This study is currently enrolling patients (NCT02369016). Citation Format: Grzegorz S. Nowakowski, Igor Gorbatchevsky, Florian Hiemeyer, Lisa Cupit, Barrett H. Childs.

A phase II study of copanlisib in patients with relapsed/refractory indolent or aggressive lymphoma reported a promising overall response rate of up to 53% for patients in the indolent NHL group (Dreyling et al., ENA 2014). The objective of this study is to evaluate the efficacy and safety of copanlisib in patients with indolent B-cell NHL relapsed after or refractory to standard therapy. Methods: In this study, patients meeting the following criteria will be eligible for enrollment: histologically confirmed diagnosis of indolent B-cell NHL, with follicular lymphoma (FL) grade 1-2-3a, marginal zone lymphoma (MZL; splenic, nodal, or extra-nodal), small lymphocytic lymphoma (SLL) with absolute lymphocyte count &amp;lt; 5 × 109/L at the time of diagnosis and at study entry, or lymphoplasmacytoid lymphoma/Waldenström macroglobulinemia (LPL/WM), and who have previously received ≥ 2 prior lines of therapy with rituximab and an alkylating agent and must be refractory to the last treatment with rituximab (refractory defined as not responding or progressing within 6 months of the last course of treatment). Patients will be randomized in 2:1 manner to receive 60 mg of copanlisib administered intravenously on days 1, 8 and 15 of a 28-day cycle or placebo administered on the same schedule. Patients will be treated until disease progression or intolerable toxicity. Patients in the placebo arm will be allowed to cross-over to receive follow-up treatment with copanlisib, after confirmed disease progression. Dose reductions due to toxicities to 45 mg and 30 mg will be allowed. Radiologic tumor assessment will be performed every 12, 16 or 24 weeks for years 1, 2, and 3, respectively. The primary endpoint will be progression-free survival (PFS). Secondary objectives include overall objective response rate (ORR), duration of response (DOR), time to progression (TTP), complete response rate (CRR), overall survival (OS), time to deterioration as well as time to improvement in disease-related symptoms. Exploratory objectives will include secondary PFS after first progression in placebo-treated patients who cross over to receive copanlisib and time to improvement and the time to deterioration in disease-related symptoms-physical (DRS-P) of at least 3 points as measured by the FLymSI-18 questionnaire. Approximately 189 patients who meet the eligibility criteria will be randomized 2:1, with approximately 126 patients in the copanlisib monotherapy arm and approximately 63 patients in placebo arm. The study is planned to detect a 132% increase in median PFS in copanlisib versus placebo (i.e. to detect a hazard ratio of 0.43), using a stratified log-rank test. Citation Format: Grzegorz S.

Profile of pomalidomide and its potential in the treatment of myelofibrosis.

Myelofibrosis, a Philadelphia-negative myeloproliferative neoplasm, is in a new treatment era after the discovery of the JAK2V617F mutation in 2005. JAK inhibitors boast improvements in disease-related symptoms, splenomegaly, and overall survival; however, treatment of myelofibrosis remains a challenge, given the lack of improvement in cytopenias with these agents. Second-generation immunomodulatory agents, such as pomalidomide, have shown efficacy in myelofibrosis-associated anemia within multiple clinical trials. Five major pomalido-mide clinical trials have been completed to date, and demonstrate tolerability and efficacy with low-dose pomalidomide (0.5 mg/day) in the treatment of myelofibrosis, and no clinical benefit of elevated dosing regimens (≥2.5 mg/day). Anemia responses ranged from 17% to 36% as per the International Working Group for Myelofibrosis Research and Treatment consensus guidelines, while improvements in splenomegaly were rare, and observed in <1% of most clinical trials. In comparison with earlier immunomodulatory agents, pomalidomide was associated with an improved toxicity profile, with substantially lower rates of myelosuppression and neuropathy. Given the low overall response rate to pomalidomide as a single agent, combination strategies are of particular interest for future studies. Pomalidomide is currently being tested in combination with ruxolitinib, and other novel combinations are likely on the horizon.

Progression-free survival, patient-reported outcomes and the Holy Grail.

In oncology clinical trials, overall survival (OS) remains the gold standard for clinical beneft. However, because there are so many available treatment options for most types of cancer, survival analysis in clinical trials is often confounded by subsequent therapies. Progression-free survival (PFS) is an endpoint not so confounded, and one that requires fewer patients and less time to arrive at a conclusion about a new therapy. As a result, an ever-increasing number of oncology clinical trials are launched in which PFS is used as the primary endpoint. Several years ago, Pazdur emphasized that the time-to-progression endpoint must use the same evaluation techniques and schedules for all treatment arms and he recommended blinding of trials or at minimum, the use of an external blinded radiographic review committee. He also noted that improvement in disease-related symptoms qualifes as clinical beneft and may therefore be an appropriate endpoint for drug approval.

Is the Evaluation of Quality of Life in NSCLC Trials Important? Are the Results to be Trusted?

The majority of patients with non-small cell lung cancer present at the time of diagnosis with stage IV metastatic disease and they experience 2 or more disease-related symptoms. These symptoms may have a negative impact on their health-related quality of life (HR QOL). Data has shown many of these patients prefer a therapy to improve their symptoms rather than receive a therapy which slightly prolongs their survival without improving their symptoms. The improvement of disease-related symptoms on a specific drug or regimen augments the significance of prolongation of the progression-free survival or the response rate as well as symptom worsening. The choice of the questionnaires to evaluate patients’ reported outcomes and HR QOL benefits and the methods of collecting the data and their interpretations are very important. Only if the data are collected and analyzed properly will they be meaningful and can then be viewed as components that add the total value to a treatment and provide a comprehensive picture of the benefits and risks of a certain anticancer therapy.

Gefitinib Combined With Stereotactic Radiosurgery in Previously Treated Patients With Advanced Non–Small Cell Lung Cancer

Disease progression remains the major challenge in the management of advanced (stage IIIb or IV) non-small cell lung cancer (NSCLC) after the failure of first-line or second-line chemotherapy, or even of targeted therapies such as gefitinib. The current study evaluated the tolerability and efficacy of stereotactic body radiation therapy (SBRT) in combined with gefitinib as a second-line or third-line treatment in patients with advanced NSCLC. Fourteen advanced NSCLC patients showing disease progression after platinum-based chemotherapy regimens were recruited. Eligible patients started taking gefitinib (250 mg/d) 7 days before SBRT and continued for 1 year until disease progression, unacceptable toxicity or withdrawal of consent. SBRT was delivered in median 3 fractions within 3 to 5 days. Treatment-associated toxicity was assessed according to the Common Terminology Criteria for Adverse Events (v.3.0). Local control was assessed according to the Response Evaluation Criteria in Solid Tumors criteria and symptom assessments were measured by the Functional Assessment of Cancer Therapy-Lung instrument (V4.0). With an overall median follow-up of 15.5 months (range, 4 to 27 mo), most patients were well tolerated with common side effects from grade 1 to 2. No grade 4 or higher toxicity was encountered. The clinical disease-related symptom improvement rate was reached 57.1% with the median duration of symptom improvement of 8.0 months. The 1-year local control and overall survival (OS) rates were 83.9% and 69.6%, respectively. The median progression-free survival and OS were 7.0 and 19.0 months, respectively. The SBRT combined with gefitinib is a promising treatment strategy for advanced (stage IIIb or IV) NSCLC after the failure of previously chemotherapy. This method improves local control and disease-related symptoms with tolerated toxicity, and even increases the progression-free survival and OS.
