Promoting continuity of care for homeless adults with unmet health needs: The role of brief interventions
Promoting timely and continuous care for people experiencing homelessness has been a challenge in many jurisdictions, plagued by access barriers and service fragmentation. As part of a larger programme evaluation, this study used qualitative methods to examine the role of a brief interdisciplinary intervention in supporting continuity of care for this population in a large Canadian urban centre. The intervention provides time-limited case management, primary and psychiatric care, and peer accompaniment to homeless adults with unmet health needs discharged from hospital. Data were collected from 52 study participants between July 2013 and December 2014. Three focus groups were conducted with service providers and people with lived experience of homelessness, and 29 individual, semi-structured interviews were conducted with service users and other key informants. Transcripts were analysed using thematic analysis. Analysis was informed by existing frameworks for continuity of care, while remaining open to additional or unexpected findings. Findings suggest that brief interdisciplinary interventions can promote continuity of care by offering low-barrier access, timely and responsive service provision, including timely connection to long-term services and supports, appropriate individualised services and effective co-ordination of services. Although brief interdisciplinary interventions were perceived to promote access, timeliness and co-ordination of care for this population with complex health and social needs, gaps in the local service delivery context can present persisting barriers to care comprehensiveness and continuity.We appreciate funding support from the Canadian Institutes of Health

Integrating Hospital and Community Care for Homeless People with Unmet Mental Health Needs: Program Rationale, Study Protocol and Sample Description of a Brief Multidisciplinary Case Management Intervention
The Coordinated Access to Care for Homeless People (CATCH) program is a brief multidisciplinary case management intervention for homeless adults discharged from hospital in Toronto, Canada. Here we describe the rationale for CATCH program development, details of the mixed methods evaluation underway, and the characteristics of 225 CATCH service users. Funded in 2010 by the local health authority, CATCH aimed to improve access, continuity of care, health and service use outcomes for homeless adults discharged from hospital. To assess the feasibility, acceptability and impact of the program, a mixed-methods case study was undertaken in 2013. In total, 225 CATCH program users were enrolled in the study and completed quantitative survey measures at program entry to assess key health and social outcomes using a pre-post cohort study design. Follow-up assessments took place at 3- and 6- months. At study entry, most participants were male (79%), white (65%), Canadian-born (74%), single or never married (60%), and their average age was 39.9 ± 12.0 years. Nearly all participants (88%) had at least one emergency department visit in the past six months, more than half (53%) indicated at least three chronic health conditions, and 44% indicated at least three mental health diagnoses. In addition, qualitative data was collected to evaluate the experiences of continuity of care and challenges during care transitions for this population using in-depth interviews with a sample of CATCH service users (n=22) and managers of partnered organizations (n=7), as well as focus groups with CATCH staff (n=8), other service providers (n=7) and people with lived experience of homelessness (n=8). Improving health and health service use outcomes among homeless adults with chronic health conditions are key priorities in many jurisdictions. Future findings can inform service delivery to homeless adults discharged from hospital, by exposing factors associated with positive program outcomes, as well as barriers and facilitators to continuity of care for this disadvantaged population

CLL-120 Pirtobrutinib, A Highly Selective, Non-Covalent (Reversible) BTK Inhibitor in Previously Treated CLL/SLL: Updated Results from the Phase 1/2 BRUIN Study
Pirtobrutinib after a Covalent BTK Inhibitor in Chronic Lymphocytic Leukemia.
BACKGROUND: Patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) have poor outcomes after the failure of covalent Bruton\u27s tyrosine kinase (BTK) inhibitor treatment, and new therapeutic options are needed. Pirtobrutinib, a highly selective, noncovalent (reversible) BTK inhibitor, was designed to reestablish BTK inhibition.
METHODS: We conducted a phase 1-2 trial in which patients with relapsed or refractory B-cell cancers received pirtobrutinib. Here, we report efficacy results among patients with CLL or SLL who had previously received a BTK inhibitor as well as safety results among all the patients with CLL or SLL. The primary end point was an overall response (partial response or better) as assessed by independent review. Secondary end points included progression-free survival and safety.
RESULTS: A total of 317 patients with CLL or SLL received pirtobrutinib, including 247 who had previously received a BTK inhibitor. Among these 247 patients, the median number of previous lines of therapy was 3 (range, 1 to 11), and 100 patients (40.5%) had also received a B-cell lymphoma 2 (BCL2) inhibitor such as venetoclax. The percentage of patients with an overall response to pirtobrutinib was 73.3% (95% confidence interval [CI], 67.3 to 78.7), and the percentage was 82.2% (95% CI, 76.8 to 86.7) when partial response with lymphocytosis was included. The median progression-free survival was 19.6 months (95% CI, 16.9 to 22.1). Among all 317 patients with CLL or SLL who received pirtobrutinib, the most common adverse events were infections (in 71.0%), bleeding (in 42.6%), and neutropenia (in 32.5%). At a median duration of treatment of 16.5 months (range, 0.2 to 39.9), some adverse events that are typically associated with BTK inhibitors occurred relatively infrequently, including hypertension (in 14.2% of patients), atrial fibrillation or flutter (in 3.8%), and major hemorrhage (in 2.2%). Only 9 of 317 patients (2.8%) discontinued pirtobrutinib owing to a treatment-related adverse event.
CONCLUSIONS: In this trial, pirtobrutinib showed efficacy in patients with heavily pretreated CLL or SLL who had received a covalent BTK inhibitor. The most common adverse events were infections, bleeding, and neutropenia. (Funded by Loxo Oncology; BRUIN ClinicalTrials.gov number, NCT03740529.)

Pirtobrutinib, A Next Generation, Highly Selective, Non-Covalent BTK Inhibitor in Previously Treated CLL/SLL: Updated Results from the Phase 1/2 BRUIN Study
Abstract
Background: Covalent BTK inhibitors (BTKi) have transformed the management of chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), but these treatments are not curative and many patients (pts) will require additional treatment. Covalent BTKi share pharmacologic liabilities (e.g. low oral bioavailability, short half-life) that collectively may lead to suboptimal BTK target coverage, for example in rapidly proliferating tumors with high BTK protein turnover such as accelerating CLL/SLL, ultimately manifesting as acquired resistance in some pts. To address these limitations, pirtobrutinib, a highly selective, non-covalent BTKi that inhibits both wild type (WT) and C481-mutated BTK with equal low nM potency was developed. In the phase 1/2 BRUIN study, pirtobrutinib achieved pharmacokinetic exposures that exceeded its BTK IC96 at trough, was well tolerated and demonstrated promising efficacy in CLL/SLL pts regardless of prior therapy, number of prior lines of therapy, or BTK C481 mutation status(Mato et al. Lancet 2021;397,10277:892-901).
Methods: BRUIN is a phase 1/2 multicenter study (NCT03740529) of oral pirtobrutinib monotherapy in pts with advanced B-cell malignancies who have received >2 prior therapies. Pirtobrutinib was dose escalated in a standard 3+3 design in 28-day cycles. The primary objective for phase 1 was to determine the recommended phase 2 dose (RP2D) and the primary objective of phase 2 was overall response rate (ORR); secondary objectives included duration of response (DoR), progression-free survival (PFS), overall survival (OS), safety and tolerability, and pharmacokinetics. Efficacy evaluable pts included all dosed pts who underwent their first response evaluation or discontinued therapy. Response was assessed every 8 weeks from cycle 3, and every 12 weeks from cycle 13 and was measured according to the iwCLL 2018 criteria, including PR with lymphocytosis (PR-L). Safety was assessed in all pts (CLL/SLL and NHL).
Results: As of 27 September 2020, 323 pts with B-cell malignancies (170 CLL/SLL, 61 MCL, 26 WM, 26 DLBCL, 13 MZL, 12 FL, 9 RT, and 6 other [other transformation, B-PLL and hairy cell leukemia]) were treated on 7 dose levels (25-300mg QD). Among the 170 pts with CLL/SLL, the median age was 69 (range 36-88) years. Median number of prior lines of therapies was 3 (range 1-11). Majority of the CLL/SLL pts had received a prior BTKi (86%), an anti-CD20 antibody (90%), or a chemotherapy (82%); 21% had received a PI3K inhibitor and 34% a BCL2 inhibitor. High risk molecular features such as 17p deletion, TP53 mutation, and unmutated IGHV were present in 25% (20/81), 30% (27/91), and 88% (71/81) of pts, respectively. No DLTs were reported and MTD was not reached (n=323). 200mg QD was selected as the RP2D. Fatigue (20%), diarrhea (17%), and contusion (13%) were the most frequent treatment-emergent adverse events regardless of attribution or grade seen in >10% of pts (n=323). The most common adverse event of grade ≥3 was neutropenia (10%). Treatment-related hemorrhage and hypertension occurred in 5 (2%) and 4 (1%) pts, respectively. Five (1%) pts discontinued due to treatment-related adverse events. At the efficacy cutoff date, 139 CLL/SLL pts were efficacy-evaluable with a median follow up time of 6 months (range 0.16-17.8+). The ORR was 63% (95% CI 55-71) among the 139 efficacy evaluable pts with 69 PRs (50%), 19 PR-Ls (14%), 45 SDs (32%), and 1 PD (1%), and 5 (4%) pts discontinued prior to first response assessment. Among the 121 BTKi pretreated pts, the ORR was 62% (95% CI 53-71). Responses deepened over time with an ORR of 86% among the pts with at least 10 months follow-up. ORR was similar in pts who discontinued prior BTKi due to progression (67%), or adverse events or other reasons (52%). Of the 88 responding pts, all except 5 remained on therapy (4 progressed and 1 achieved a PR and electively discontinued treatment to undergo transplant). The longest-followed responding patient as of the data cutoff date had been on treatment for 17.8+ months.
Conclusion: Pirtobrutinib demonstrated promising efficacy in heavily pretreated CLL/SLL pts following multiple prior lines of therapy, including a covalent BTKi and a BCL2 inhibitor, and in pts with BTK C481 mutations. Pirtobrutinib was well tolerated and exhibited a wide therapeutic index. Updated data, including approximately 100 new pts with CLL and an additional 10 months since the prior data cut will be presented.

Post-hospitalization experiences of older adults diagnosed with diabetes: “It was daunting!”
Multimorbidity combined with geriatric syndromes in older adults with diabetes exacerbate their risks for poor post-discharge outcomes. The purpose of this study was to examine self-described hospital-to-home transition challenges encountered by older adults with a diagnosis of diabetes within the first 30 days following discharge. The qualitative responses for this paper emerged from a larger mixed methods study (n = 96) in which participants provided free responses specifying transition challenges during follow-up telephone interviews on the 7th day (n = 67) and 30th day (n = 55) post-discharge. Using inductive content analysis techniques four major themes emerged: a) “The daily stuff is difficult”; b) engineering care at home is complex; c) “life is very difficult”; and d) managing complex health problems is difficult. Findings suggest existing system-level metrics such as readmission rates fail to capture the complex and dynamic interplay of personal, family and social factors which complicate hospital-to-home transitions of older adults with pre-existing diabetes
Pseudorapidity densities of charged particles with transverse momentum thresholds in pp collisions at √ s = 5.02 and 13 TeV
The pseudorapidity density of charged particles with minimum transverse momentum (pT) thresholds of 0.15, 0.5, 1, and
2 GeV/c is measured in pp collisions at the center of mass energies of √s=5.02 and 13 TeV with the ALICE detector. The study is carried out for inelastic collisions with at least one primary charged particle having a pseudorapidity (η) within 0.8pT larger than the corresponding threshold. In addition, measurements without pT-thresholds are performed for inelastic and nonsingle-diffractive events as well as for inelastic events with at least one charged particle having
|η|2GeV/c), highlighting the importance of such measurements for tuning event generators. The new measurements agree within uncertainties with results from the ATLAS and CMS experiments obtained at √s=13TeV.
