Abstract
ECOG/ACRIN 1412 (E1412) is a randomized, phase II open-label study of lenalidomide/RCHOP vs. RCHOP alone in adults with newly diagnosed de novo diffuse large B-cell lymphoma (DLBCL) and requires NanoString gene expression profiling (GEP) for cell-of-origin testing. Because of high ineligibility rate on retrospective expert central pathology review (ECPR), real-time (RT) ECPR was instituted to confirm diagnosis and ensure adequate tissue for GEP prior to study enrollment. Goal was notification of eligibility within 2 working days (WD). Initially, 208 patients were enrolled, 74 (35.6%) of whom were deemed ineligible by retrospective ECPR. After initiation of RT-ECPR, 219 patients were registered. Of these, 73 (33.3%) were ineligible and were declined enrollment; 47 (21.5% of total) had an ineligible diagnosis on RT-ECPR, and 26 (11.9% of total) had inadequate tissue. Because the 73 ineligible patients were never enrolled, no study slots were “lost” during this phase. Notification of eligibility occurred in an average of 1 WD (Range 0–4) with 97.3% within 2 WD. This novel RT-ECPR serves as a model for future lymphoma trials. Real-time ECPR can help to reduce costs and ensure that study slots accurately reflect the targeted population. In the precision-medicine era, rapid collection of relevant pathology/biomarker data is essential to trial success.

Abstract
TPS44 Background: Immune checkpoint blockade (ICB) using agents that target the priming phase (i.e. CTLA-4) and effector phase (e.g. PD-1) of host immunity, used individually or in combination, has emerged as a therapeutic strategy for cancers. However, little is known about the safety, tolerability and efficacy of ICB in patients (pts) with HIV infection and cancer. Methods: AMC 095 (NCT02408861) is a multicenter, international phase I study of the PD-1 inhibitor, nivo alone or in combination with a CTLA-4 inhibitor, ipi, in 2 cohorts stratified by CD4 counts (Stratum 1: CD4 counts≥200/uL and Stratum 2: CD4 count 100-200/uL) with additional expansion cohorts at the recommended phase II dose in pts with ST and cHL. The primary study objective is to determine the safety and feasibility of nivo alone and the nivo+ipi combination. Secondary objectives are to evaluate the effects of single agent nivo, and ipi+ nivo, on HIV replication and immune function (HIV viral load in plasma using conventional assay, CD4+, and CD8+ cells), and to obtain preliminary information regarding response. The trial was initiated in 8/15, as of 9/30/17, the study is ongoing, and 14 pts have been enrolled. Updated information on the safety and responses will be presented. Clinical trial information: NCT02408861. Funded by the NCI Grant #UM1CA121947.[Table: see text]

Abstract
Abstract
Purpose: NCI-Molecular Analysis for Therapy Choice (NCI-MATCH/EAY131), by ECOG-ACRIN (EA) and NCI, is the first national signal-finding trial to incorporate centralized NGS testing to direct patients (pts) to molecularly targeted parallel phase 2 treatment arms. We report status of accrual from opening on 08/12/15 thru 07/16/17 and future plans.
Methods: Eligible pts have advanced/refractory solid tumors, lymphoma, or myeloma. Drug treatments and molecular targets require stringent levels of evidence (LOE). Each arm (N-35) has a phase 2 dose, a molecular abnormality believed to predict response, and evidence of clinical activity. Pts must have enrolled by 05/22/17 with intent to submit fresh tissue or recent clinical biopsy. Tumor cores are shipped to the EA Central Biorepository & Pathology Facility at MD Anderson Cancer Center for evaluation of histopathology and % tumor; PTEN, MLH1, and MSH2 IHC; and RNA/DNA extraction. NGS is performed in one of 4 CLIA-accredited laboratories using the NCI-MATCH adapted Oncomine™ panel (Version 1.0; 143 genes with >4000 reported variants including SNVs, indels, amplifications, and gene fusions). When an actionable mutation of interest (aMOI) or relevant IHC result is identified, the pt is assigned to treatment by a custom-designed informatics system (MATCHbox). If >1 aMOI present, the pt is assigned by the variant with the highest LOE.
Results: As of 07/16/17, 5963 tumors were screened for 30 treatment arms. The assay success rate is 93%; median turnaround is 15 days (from sample receipt to return of results). 38.2% of pts have common cancers: colorectum (15.4%), breast (12.8%), lung (7.4%), and prostate (2.6%); 61.8% have less common tumors. The current overall match rate to aMOI’s is 18% (95% CI 17%, 19%); aMOI prevalence rates range from 3.47% to zero. The match rate also varies across tumor types: <10% in pancreatic & SCLC; >30% in bladder/urinary tract, uterine, and head/neck cancer. 998 pts have been assigned to Rx; 69% have enrolled. Of 30 arms, 8 have enrolled ≥ 35 pts; some arms with higher prevalence rates have been expanded to N=70 to accommodate pts with matching aMOIs. Arms with less frequent aMOIs will not complete accrual within the 6,000-pt central screening goal, leading to identification of pts for screening based on approved high-volume NGS labs’ assay results, verified centrally.
Conclusions: NCI-MATCH screened ~6000 pts at a rate that far exceeded expectations, and with acceptable toxicity; NGS was successful in 93%, well above the industry average of ~80%. The pace of enrollment, along with the trial’s availability at 1100+ sites, reflects the broad interest in the promise of genomics and the ability of such a trial to deliver on that promise. Lower accrual to "rare variant" arms led to use of high-volume NGS laboratories to complete the study. Follow-up will determine whether matching drugs to molecular targets results in meaningful response rates and improved patient outcome.

Abstract
Abstract
Oncology has undergone major changes in systemic treatment options, from chemotherapy to antiangiogenic agents to tyrosine-kinase inhibitors to immunotherapy. Historically, a therapeutic agent is tested in separate trials as monotherapy or combined with investigational or approved agents/modalities, to determine antitumor activity in each histology based on the premise that each histology responds differently to the same treatment. This paradigm is time consuming and may or may not make use of molecular characterization to test each agent in each histology. However, with the expansion of biologic understanding and development of various biomarkers, e.g., estrogen receptor and Her 2 amplification, we move beyond the basic paradigm of general histology to one in which treatment is based upon molecular characteristics of the tumor. Examples of recent discoveries from this more modern paradigm are (1) multiple histologies sharing a common molecular profile and (2) a subset within a single histology having a given molecular characteristic. Various agents have been tested singularly in terms of molecular aberrations and histology, e.g., ALK inhibitors and NSCLC. However, with the rapid increase in the number of targeted agents in development, more facile and efficient clinical trial designs are needed.
The National Cancer Institute (NCI) and ECOG-ACRIN Cancer Research Group (ECOG-ACRIN) collaborated in designing the Molecular Analysis for Therapy Choice trial (NCI-MATCH or EAY131), the first large-scale signal-finding precision medicine oncology trial in the United States to incorporate centralized NGS testing to direct patients to parallel (nonrandomized) phase II treatment arms under a master protocol. The trial is being conducted by the NCI National Clinical Trials Network (NCTN), with ECOG-ACRIN leading the trial. More than 100 investigators from across the NCTN adult cancer-oriented member groups (Alliance for Clinical Trials in Oncology, ECOG-ACRIN, NRG Oncology, and SWOG) have worked collaboratively to design and lead what is currently 30 treatment arms (subprotocols), with more arms in development. Wide-scale NCTN investigator involvement ensures use of the latest knowledge to define the actionable mutations required for eligibility and to make evidence-based selections of experimental agents.
In NCI-MATCH, patients are assigned treatment based on the genomic alterations found in their tumors through genomic sequencing and other tests at the time of initial enrollment for screening. Unlike other phase II trials, each arm is open to advanced solid tumors, lymphomas, or myeloma that share a set of molecular aberrations, not restricted to a single histology. This strategy accommodates and encourages enrollment of rare tumors for which there are often no standard treatments and limited clinical trial options.
NCI-MATCH has 10-30 concurrent treatment arms available to patients at any given time, testing both investigational agents and FDA-approved drugs for new indications. Most treatment arms have an enrollment goal of 35 patients, with some arms that address tumor gene variants of higher prevalence expanded to 70 patients. Together, the NCTN and NCI Community Oncology Research Program provide infrastructure for many clinical sites (>1100) to participate, providing ready access to physicians and patients; screening enrollment has occurred in all 50 states in the U.S, the District of Columbia, and Puerto Rico. A specific assay was developed for the trial (the MATCH assay), and a laboratory network was organized to rapidly process the tissue and efficiently interrogate for mutations. NCI and ECOG-ACRIN statisticians developed the analysis plan and are currently maintaining data that are closely monitored by safety experts for any adverse event signals. Lastly, a bioinformatics system (MATCHbox) was developed to coordinate molecular data collection and support rule-based decision-making based on those data.
Because genomics in oncology is rapidly expanding and evolving, NCI-MATCH required flexibility to accommodate brisker screening accrual than anticipated, and adaptation to constantly emerging information about new drugs and new molecular alterations. The goal to sequence the tumors of 6,000 patients with NCI funding was achieved two years ahead of schedule, but that cohort was not sufficient to fill all the arms—in particular, those aimed at the most rarely occurring tumor gene aberrations. Currently, the goal for the trial is to complete the open treatment arms by allowing for designated commercial and academic laboratories to notify ordering physicians when genomic tests they ordered to guide clinical care indicate a potential eligibility to a NCI-MATCH arm with a rare variant and allow for enrollment to the relevant treatment subprotocol if the patient meets all subprotocol eligibility criteria. The tissue confirmation of the molecular abnormality on the MATCH assay by the central laboratories will be accomplished after subprotocol enrollment so that patient treatment will not be delayed for confirmation. A demonstration project is now under way to test the applicability of this approach and potentially develop common standards for future use. With tumor sequencing becoming a more and more common practice in oncology, this may allow patients with mutations of low prevalence to have investigational treatment options.
NCI-MATCH is expanding its panel and definition of actionable mutations to allow greater flexibility to incorporate in real time new mutations supported with adequate levels of evidence. The valuable genomic and clinical outcome data collected in the trial will permit evaluation of efficacy of targeting certain actionable mutations with a specific agent. In addition, biospecimens are being collected to build a rich resource for conducting auxiliary biology studies that may answer questions about prevalence of mutations in the metastatic setting, prevalence of mutations in rare histologies, and resistance mechanisms of various targeted therapy. At this meeting, two abstracts will provide an overall trial update and present information about the prevalence of mismatch repair deficiency (dMMR) in the centrally screened population.

Abstract
Purpose People with HIV are living longer as a result of effective antiretroviral therapy. Cancer has become a leading cause of morbidity and mortality in this patient population. However, studies of novel cancer therapeutics have historically excluded patients with HIV. Critical review of eligibility criteria related to HIV is required to accelerate development of and access to effective therapeutics for HIV-infected patients with cancer and make studies more generalizable to this patient population. Methods From January through April 2016, the HIV Working Group conducted a series of teleconferences; a review of 46 New Drug Applications from registration studies of unique agents studied in adults with cancer that led to the initial US Food and Drug Administration approval of that agent from 2011 to 2015; and a review of HIV-related eligibility criteria from National Cancer Institute-sponsored studies. Results were discussed and refined at a multistakeholder workshop held May 12, 2016. The HIV Working Group developed recommendations for eligibility criteria that focus on pharmacologic and immunologic considerations in this patient population and that balance patient safety, access to appropriate investigational agents, and study integrity. Results Exclusion of patients with HIV remains common in most studies of novel cancer agents. Models for HIV-related eligibility criteria in National Cancer Institute-sponsored studies are instructive. HIV infection itself should no longer be an exclusion criterion for most studies. Eligibility criteria related to HIV infection that address concurrent antiretroviral therapy and immune status should be designed in a manner that is appropriate for a given cancer. Conclusion Expanding clinical trial eligibility to be more inclusive of patients with HIV is justified in most cases and may accelerate the development of effective therapies in this area of unmet clinical need.

Abstract
Primary CNS lymphoma (PCNSL) harbors mutations that reinforce B cell receptor (BCR) signaling. Ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor, targets BCR signaling and is particularly active in lymphomas with mutations altering the BCR subunit CD79B and MYD88. We performed a proof-of-concept phase Ib study of ibrutinib monotherapy followed by ibrutinib plus chemotherapy (DA-TEDDi-R). In 18 PCNSL patients, 94% showed tumor reductions with ibrutinib alone, including patients having PCNSL with CD79B and/or MYD88 mutations, and 86% of evaluable patients achieved complete remission with DA-TEDDi-R. Increased aspergillosis was observed with ibrutinib monotherapy and DA-TEDDi-R. Aspergillosis was linked to BTK-dependent fungal immunity in a murine model. PCNSL is highly dependent on BCR signaling, and ibrutinib appears to enhance the efficacy of chemotherapy.

Abstract
Because of its rarity and high curability, progress in advancing therapeutics in Burkitt lymphoma (BL) has been difficult. Over recent years, several new mutations that cooperate with MYC have been identified, and this has paved the way for testing novel agents in the disease. One of the challenges of most standard approaches typically used is severe treatment-related toxicity that often leads to discontinuation of therapy. To that point, there has been recent success developing intermediate intensity approaches that are well tolerated in all patient groups and maintain high cure rates in a multicenter setting.

Abstract
7547 Background: E1412 statistical design is based on results of lenalidomide/RCHOP (R2CHOP) vs RCHOP in ABC-DLBCL as determined by NanoString gene expression profiling (GEP). Central pathology review (CPR) was conducted to confirm diagnosis and to ensure adequate tissue for GEP. Initially, CPR occurred after randomization and treatment initiation. Due to high ineligibility rate (IR), the protocol was amended to include real-time CPR to determine patient eligibility prior to study enrollment. We describe the revision and how it affected the IR. Methods: Pre-amendment, CPR was done retrospectively. Post-amendment, CPR was done prior to enrollment, in real time, on a submitted tissue block, H&E, and CD20 slides. Based on CPR, if a diagnosis of DLBCL was confirmed, and sufficient tissue remained for GEP, a patient was deemed eligible and the submitter was notified by fax. Protocol goal was notification within 2 working days (WD) of receipt of materials at the CPR site. Results: Pre-amendment, 219 patients were enrolled. Material was typically received at the CPR site 6-9 months after patient registration. The IR with CPR was 36% for all those enrolled, and 26% for patients with adequate tissue for GEP. Post-amendment, 218 patients were submitted for CPR: 145 (67%) were eligible; 73 (33%) were ineligible. Reasons for ineligibility included insufficient tissue (n=27) or a diagnosis other than de novo DLBCL (n=46). Notification of eligibility occurred in a median of 2 WD (Mean 2 WD; Range 1-5 WD). 90% were notified within the protocol goal of 2 WD. GEP for all enrolled was completed within 6 weeks of CPR. Conclusions: The success of this novel, real-time CPR serves as a model for the future of NCTN DLBCL trials. When CPR is performed rapidly prior to enrollment, study slots may more accurately reflect the target population and eliminate excess costs. In the precision medicine era, rapid collection of relevant pathology and biomarker data is essential to trial success. Study Coordinated by ECOG-ACRIN Cancer Research Group (Robert L. Comis, MD and Mitchell D. Schnall, MD, PhD, Group Co-Chairs), supported by NCI grant # CA180820, CA180794, CA180790, CA180799, CA180833.

Abstract
7006 Background: AlloHCT has been regarded as risky in HIV pts, with concern about fatal infection. We set out to assess feasibility and safety of alloHCT in this first prospective multicenter trial. Methods: The primary endpoint was 100-day non-relapse mortality (NRM). Pts had drug-susceptible HIV; age ≥ 15 yr; adequate organ function; acute myeloid leukemia (AML) or acute lymphocytic leukemia (ALL), high risk myelodysplastic syndrome (MDS), or Hodgkin (HL) or non-Hodgkin lymphoma (NHL) beyond first CR; an 8/8 HLA-matched related or at least a 7/8 unrelated donor. Pts received myeloablative (MA) or reduced intensity (RI) regimens. HIV outgrowth assays (VOA) were performed with resting CD4+T-cells in pts who had clinically undetectable HIV plasma RNA at 1 yr. Results: Between 5/2012 and 12/2015, 17 pts underwent alloHCT. Pts were: male (17); white (11), African American (3), Other/Unknown (3); median age 47 yrs (25-64). Associated malignancies were AML (9), ALL (2), MDS (2), HL (1), NHL (3). Median CD4 was 224 (55-833). Conditioning was MA (8) and RI (9). At 100 days there was no NRM, 13 pts were in CR, 4 pts had relapsed/progressive disease; and 8 pts achieved complete chimerism. The cumulative incidence of Grades (Gr) II-IV acute Graft vs Host Disease (GvHD) was 41 % (95%CI: 18 %, 64%). At 6 mo, OS was 82 % (95% confidence interval [CI]: 55%, 94%); 9 pts achieved complete chimerism. At 1 year, OS was 57 % (CI: 31%, 77 %); 8 deaths were from relapsed/progressive disease (5), acute GvHD (1), adult respiratory distress syndrome (1) and liver failure (1). Infections were reported in 11 pts (3 Gr 2, 8 Gr 3). Infectious HIV was detected by VOA in 2 of 3 pts who were mixed chimeras but 0 of 2 who were 100% donor. Median follow up of survivors is 24 mo (7 to 27 ). Conclusions: HIV pts with heme malignancies underwent MA or RI alloHCT without any100-day NRM and there were no infectious deaths at 1 year. AlloHCT should be considered the standard of care for HIV pts who meet usual eligibility criteria. Clinical trial information: NCT01410344.

Abstract
e14077 Background: Although cancer has long been a recognized hallmark of the HIV epidemic, the preservation of immunologic health with modern antiretroviral therapy (ART) and aging has resulted in a population increasingly susceptible to cancers not traditionally associated with advancing immunosuppression. Several of these cancers (including lung, anal and head & neck) are seen in excess compared to the background population. Defining tolerability of standard treatments and analyzing potential interactions between ART and chemotherapy provides evidence necessary to mitigate treatment disparities. Methods: We conducted a study to evaluate the tolerability of PCb in HIV+ cancer pts. AMC-078 (NCT01249443), originally designed as a phase I of vorinostat in combination with fixed doses of P (at 175mg/m2) and Cb (AUC 6) every 3 weeks, was amended to study pts treated with PCb alone after phase III testing in the background population was negative for the combination in lung cancer. Eligibility criteria: PS ≤ 2, advanced solid tumor and normal organ function, including CD4 count > 100 cells/mcL on stable ART. Up to 6 cycles of PCb were permitted. Clinically significant adverse events (AE) in prior cycles were managed by dose reductions. Results: 17 pts (10M/7F; median CD4, 389/mcL) were accrued, including lung (9) and anal (3) cancers; 8 pts had ritonavir (potent CYP inhibitor)-containing ART. 65 PCb cycles were administered to 16 evaluable pts, for a mean of 4+ cycles/pt; only 2 pts were treated with vorinostat. AE of special interest included ≥G3 (febrile) neutropenia and ≥ G2 neuropathy, below. 4 pts had partial responses (3 confirmed). Pharmacokinetic analyses (7 pts) are pending. Conclusions: PCb has similar toxicity profile in fit pts with HIV infection. No signal for worse myelosuppression or neuropathy was observed by ART regimen. Routine use of GCSF or empiric dose reduction for presumed risk is unjustified. Results support standard cancer treatment for this underserved population. Clinical trial information: NCT01249443.

A Phase Ib Study of Sorafenib (BAY 43-9006) in Patients with Kaposi Sarcoma. Oncologist 2017; 22:505-e49. [PMID: 28341759 PMCID: PMC5423501 DOI: 10.1634/theoncologist.2016-0486] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2016] [Accepted: 12/16/2016] [Indexed: 12/17/2022] Open
Abstract
LESSONS LEARNED Oral targeted agents are desirable for treatment of Kaposi sarcoma (KS); however, in patients with HIV, drug-drug interactions must be considered. In this study to treat KS, sorafenib was poorly tolerated at doses less than those approved by the U.S. Food and Drug Administration for hepatocellular carcinoma and other cancers, and showed only modest activity.Sorafenib's metabolism occurs via the CYP3A4 pathway, which is inhibited by ritonavir, a commonly used antiretroviral agent used by most patients in this study. Strong CYP3A4 inhibition by ritonavir may contribute to the observed sorafenib toxicity.Alternate antiretroviral agents without predicted interactions are preferred for co-administration in patients with HIV and cancers for which sorafenib is indicated. BACKGROUND We conducted a phase Ib study of sorafenib, a vascular epithelial growth factor receptor (VEGFR), c-kit, and platelet derived growth factor receptor (PDGFR)-targeted treatment in Kaposi sarcoma (KS). We evaluated drug-drug interactions between sorafenib and ritonavir, an HIV medication with strong CYP3A4 inhibitory activity. METHODS Two cohorts were enrolled: HIV-related KS on ritonavir (Cohort R) and HIV-related or classical KS not receiving ritonavir (Cohort NR). Sorafenib dose level 1 in cohort R (R1) was 200 mg daily and 200 mg every 12 hours in cohort NR (NR1). Steady-state pharmacokinetics were evaluated at cycle 1, day 8. KS responses and correlative factors were assessed. RESULTS Ten patients (nine HIV+) were enrolled: R1 (eight), NR1 (two). Median CD4+ count (HIV+) was 500 cells/µL. Dose-limiting toxicities (DLTs) were grade 3 elevated lipase (R1), grade 4 thrombocytopenia (R1), and grade 3 hand-foot syndrome (NR1). Two of seven evaluable patients had a partial response (PR; 29%; 95% CI 4%-71%). Steady-state area under the curve of the dosing interval (AUCTAU) of sorafenib was not significantly affected by ritonavir; however, a trend for decreased AUCTAU of the CYP3A4 metabolite sorafenib-N-oxide (3.8-fold decrease; p = .08) suggests other metabolites may be increased. CONCLUSION Sorafenib was poorly tolerated, and anti-KS activity was modest. Strong CYP3A4 inhibitors may contribute to sorafenib toxicity, and ritonavir has previously been shown to be a CYP3A4 inhibitor. Alternate antiretroviral agents without predicted interactions should be used when possible for concurrent administration with sorafenib. The Oncologist 2017;22:505-e49.

Abstract
Treatment of myeloma has benefited from the introduction of more effective and better tolerated agents, improvements in supportive care, better understanding of disease biology, revision of diagnostic criteria, and new sensitive and specific tools for disease prognostication and management. Assessment of minimal residual disease (MRD) in response to therapy is one of these tools, as longer progression-free survival (PFS) is seen consistently among patients who have achieved MRD negativity. Current therapies lead to unprecedented frequency and depth of response, and next-generation flow and sequencing methods to measure MRD in bone marrow are in use and being developed with sensitivities in the range of 10-5 to 10-6 cells. These technologies may be combined with functional imaging to detect MRD outside of bone marrow. Moreover, immune profiling methods are being developed to better understand the immune environment in myeloma and response to immunomodulatory agents while methods for molecular profiling of myeloma cells and circulating DNA in blood are also emerging. With the continued development and standardization of these methodologies, MRD has high potential for use in gaining new drug approvals in myeloma. The FDA has outlined two pathways by which MRD could be qualified as a surrogate endpoint for clinical studies directed at obtaining accelerated approval for new myeloma drugs. Most importantly, better understanding of MRD should also contribute to better treatment monitoring. Potentially, MRD status could be used as a prognostic factor for making treatment decisions and for informing timing of therapeutic interventions. Clin Cancer Res; 23(15); 3980-93. ©2017 AACR.

The PARP Inhibitor Veliparib Can Be Safely Added to Bendamustine and Rituximab and Has Preliminary Evidence of Activity in B-Cell Lymphoma. Clin Cancer Res 2017; 23:4119-4126. [PMID: 28314788 DOI: 10.1158/1078-0432.ccr-16-3068] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Revised: 01/06/2017] [Accepted: 03/08/2017] [Indexed: 11/16/2022]
Abstract
Purpose: The PARP inhibitor veliparib enhances the cytotoxicity of alkylating agents. This phase I study evaluated veliparib with the bifunctional alkylator bendamustine (VB) in patients with relapsed/refractory lymphoma, multiple myeloma, and solid malignancies, with a cohort expansion of VB with rituximab (VBR) in patients with B-cell lymphomas.Experimental Design: This dose-escalation study evaluated safety, pharmacokinetics, and preliminary efficacy of veliparib (20-400 mg twice a day, days 1-7 of 28-day cycle) and bendamustine (70 and 90 mg/m2 intravenously, days 1 and 2). A cohort expansion was conducted, which combined veliparib and bendamustine at the maximum tolerated dose (MTD) with rituximab (375 mg/m2, day 1) in patients with B-cell lymphomas. Thirty-four patients were treated in seven dose-escalation cohorts and seven patients in the dose-expansion cohort.Results: The MTD was veliparib 300 mg twice daily plus bendamustine 90 mg/m2 Dose-limiting toxicities (DLT) were anemia, nausea, hypertension, and hyperhidrosis. Grade ≥3 toxicities included lymphopenia (87.8%), anemia (19.5%), neutropenia (12.2%), thrombocytopenia (9.8%), leukopenia (9.8%), nausea (7.3%), and hypophosphatemia (7.3%). Apparent veliparib clearance was slightly lower than previously reported. Of 14 patients with lymphoma evaluable for response, five of seven (71%) on VB and six of seven (86%) on VBR achieved objective response. One patient with multiple myeloma achieved partial response.Conclusions: VB and VBR were generally well-tolerated. VBR had preliminary clinical activity in patients with B-cell lymphoma, which warrants further investigation in a phase II trial. This trial was registered at www.clinicaltrials.gov as NCT01326702 Clin Cancer Res; 23(15); 4119-26. ©2017 AACR.

Abstract
Mantle cell lymphoma (MCL) comprises around 6% of all non-Hodgkin's lymphoma (NHL) diagnoses. In younger patients, age less than 60 to 65 years, aggressive induction often followed by consolidation with autologous stem cell transplant has suggested improved outcomes in this population. Less intensive therapies in older patients often followed by maintenance have been studied or are under active investigation. However, despite recent advances, MCL remains incurable, with a median overall survival of around five years. Patients with high-risk disease have particularly poor outcomes. Treatment varies widely across institutions, and to date no randomized trials comparing intensive vs less intensive approaches have been reported. Although recent data have highlighted the heterogeneity of MCL outcomes, patient assessment for treatment selection has largely been driven by patient age with little regard to fitness, disease biology, or disease risk. One critical advance is the finding that minimal residual disease status (MRD) after induction correlates with long-term outcomes. As such, its use as a potential end point could inform clinical trial design. In order to more rapidly improve the outcomes of MCL patients, clinical trials are needed that prospectively stratify patients on the basis of MCL biology and disease risk, incorporate novel agents, and use MRD to guide the need for additional therapy.

Abstract
Peripheral T-cell lymphomas (PTCLs) are uncommon, heterogeneous, and aggressive non-Hodgkin's lymphomas. Despite progress in the last several years resulting in a deeper understanding of PTCL biology and pathogenesis, there is currently no accepted single standard of care for newly diagnosed patients, and for those with relapsed or refractory disease, prognosis is dismal. The National Cancer Institute convened a Clinical Trials Planning Meeting to advance the national clinical trial agenda in lymphoma. The objective was to identify unmet needs specific to five major lymphoma subtypes and develop strategies to address them. This consensus statement reviews recent advances in the molecular and genetic characterization of PTCL that may inform novel treatments, proposes strategies to test novel therapies in the relapsed setting with the hopes of rapid advancement into frontline trials, and underscores the need for the identification and development of active and biologically rational therapies to cure PTCL at higher rates, with iterative biomarker evaluation.

Abstract
Follicular lymphoma (FL) is the second most common lymphoid malignancy, representing 20% to 25% of all cases of non-Hodgkin's lymphoma (NHL), and the most common of the indolent NHLs. FL is considered incurable in the majority of patients with the current standard therapeutic approaches, although outcomes have improved in the last few decades with our current therapies, with a median overall survival that now exceeds 18 years. While the majority of patients with FL have improved outcomes with our current therapeutic approaches, there are patients with high-risk disease features that have inferior outcomes to these therapies. There is an urgent need to integrate novel therapeutic agents into the treatment regimens for these patients to improve outcomes with continued evaluation of biomarkers indicative of prognosis and effects of these regimens on quality of life.

Abstract
The National Clinical Trials Network lymphoid malignancies Clinical Trials Planning Meeting (CTPM) occurred in November of 2014. The scope of the CTPM was to prioritize across the lymphoid tumors clinically significant questions and to foster strategies leading to biologically informed and potentially practice changing clinical trials. This review from the Hodgkin lymphoma (HL) subcommittee of the CTPM discusses the ongoing clinical challenges in HL, outlines the current standard of care for HL patients from early to advanced stage, and surveys the current science with respect to biomarkers and the landscape of ongoing clinical trials. Finally, we suggest areas of unmet need in HL and elucidate promising therapeutic strategies to guide future HL clinical trials planning across the NCTN.

Abstract
Lymphoid malignancies are a heterogeneous group of tumors that have distinctive clinical and biological behaviors. The increasing prevalence of disease reflects both treatment advances and the fact that some of these tumors are indolent. The ability to determine treatment needs at diagnosis remains problematic for some of the tumors, such as in follicular lymphomas. Major clinical advances will likely depend on precision oncology that will enable identification of specific disease entities, prognostic determination at diagnosis, and identification of precise therapeutic targets and essential pathways. However, refinement in diagnostic evaluation is an evolving science. The ability to determine prognosis at diagnosis is variable, and for many of the lymphoid malignancies prognosis can only be made after initial treatment. Clinical trials that aim to evaluate specific features of these diseases are required in order to advance clinical practice that meaningfully addresses this important public health challenge. Herein, we describe the process and general recommendation from the National Cancer Institute (NCI) clinical trials planning meeting in November 2014 to address clinical trial design and biomarker proposals in the context of NCI-supported lymphoma clinical trials in the National Clinical Trials Network.

Abstract
Diffuse large B cell lymphoma (DLBCL) comprises multiple molecular and biological subtypes, resulting in a broad range of clinical outcomes. With standard chemoimmunotherapy, there remains an unacceptably high treatment failure rate in certain DLBCL subsets: activated B cell (ABC) DLBCL, double-hit lymphoma defined by the dual translocation of MYC and BCL2, dual protein-expressing lymphomas defined by the overexpression of MYC and BCL2, and older patients and those with central nervous system involvement. The main research challenges for DLBCL are to accurately identify molecular subsets and to determine if specific chemotherapy platforms and targeted agents offer differential benefit. The ultimate goal should be to maximize initial cure rates to improve long-term survival while minimizing toxicity. In particular, a frontline trial should focus on biologically defined risk groups not likely to be cured with cyclophosphamide, doxorubicin, vincristine, and prednisone plus rituximab (R-CHOP). An additional challenge is to develop effective and personalized strategies in the relapsed setting, for which there is no current standard other than autologous stem cell transplantation, which benefits a progressively smaller proportion of patients. Relapsed/refractory DLBCL is the ideal setting for testing novel agents and new biomarker tools and will require a national call for biopsies to optimize discovery in this setting. Accordingly, the development of tools with both prognostic and predictive utility and the individualized application of new therapies should be the main priorities. This report identifies clinical research priorities for critical areas of unmet need in this disease.

Abstract
Central nervous system (CNS) involvement is reportedly more common in acquired immunodeficiency syndrome (AIDS)-related lymphomas (ARL). We describe factors and outcomes associated with CNS involvement at baseline (CNS(B) ) and relapse (CNS(R) ) in 886 patients with newly diagnosed ARL. Of 886 patients, 800 received either intrathecal (IT) therapy for CNS(B) or IT prophylaxis. CNS(B) was found in 13%. CNS(B) was not associated with reduced overall survival (OS). There was no difference in the prevalence of CNS(B) between the pre-combination antiretroviral therapy (cART) and cART eras. 5·3% of patients experienced CNS(R) at a median of 4·2 months after diagnosis (12% if CNS(B) ; 4% if not). Median OS after CNS(R) was 1·6 months. On multivariate analysis, only CNS(B) [hazard ratio (HR) 3·68, P = 0·005] and complete response to initial therapy (HR 0·14, P < 0·0001) were significantly associated with CNS(R) . When restricted to patients without CNS(B) , IT CNS prophylaxis with 3 vs. 1 agent did not significantly impact the risk of CNS(R) . Despite IT CNS prophylaxis, 5% of patients experienced CNS(R) . Our data confirms that CNS(R) in ARL occurs early and has a poor outcome. Complete response to initial therapy was associated with a reduced frequency of CNS(R) . Although CNS(B) conferred an increased risk for CNS(R) , it did not impact OS.
