Multi-center cohort study exploring the impact of the first U.K. COVID-19 lockdown on nebulizer use in adults with cystic fibrosis in the CFHealthHub learning health system

Background: Promoting adherence to preventative inhaled therapy in cystic fibrosis (CF) is challenging despite a clear association with better outcomes. Motivation to maintain adherence is one aspect of the complex process required for sustained behavior change. Fear is recognized as an acute motivator, and the COVID-19 pandemic created a significant fear stimulus, especially in people with underlying respiratory disease. The objective of this study was to explore changes in nebulizer use in response to the COVID-19 pandemic. Method(s): This 16-center cohort study involved more than 60% of adult CF centers in England through the CFHealthHub learning health system. CFHealthHub was established in 2015 to help promote adherence to nebulized therapy. It provides people with CF and their clinicians objective usage information through nebulizers with real-time electronic data capture capability. We explored the association between the first U.K. national lockdown (March 23, 2020, to May 28, 2020) and nebulizer use, using the mixed-effect multilevel model adjusted for potential confounders including age (fitted as a nonlinear term), sex, and deprivation index. Result(s): We included 581 adults with CF participating in CFHealthHub between September 1, 2019, and August 21, 2020. Mean age was 34;49% participants were female. The range of mean weekly nebulizations per patient increased from 9 to 12 to 12 to 14 in the week after the first U.K. national lockdown before decreasing to 11 to 12 throughout the rest of the study period (Figure 1). The association between lockdown and nebulizer Figure 1: Mean weekly nebulizations in 581 adults with cystic fibrosis at 16 U.K. centers between September 2019 and August 2020.(Figure Presented) use was attenuated after adjusting for age, sex, and deprivation index (adjusted odds ratio = 0.96, 95% CI, 0.89-1.07). Conclusion(s): We did not find a sustained change in nebulizer use in response to the firstU.K. national lockdown. This may support the assertion that behavior change with respect to sustained increased nebulizer use may not be achieved when focusing on motivational aspects, especially fear, alone Copyright © 2022, European Cystic Fibrosis Society.

A PHASE 1 STUDY EVALUATING SAFETY AND EFFICACY OF PARSACLISIB IN COMBINATION WITH BENDAMUSTINE + OBINUTUZUMAB IN PATIENTS WITH RELAPSED OR REFRACTORY FOLLICULAR LYMPHOMA (CITADEL-102)

Background: Patients (pts) with follicular lymphoma (FL) generally respond well to first-line CD20-targeted therapies, such as obinutuzumab or rituximab-based regimens. However, many pts relapse and studies suggest that each subsequent relapse is associated with shorter durations of response to the next treatment. Parsaclisib is a potent and highly selective next generation PI3Kδ inhibitor. The combination of bendamustine + obinutuzumab is approved for pts with relapsed/refractory (R/R) FL. We hypothesized that adding parsaclisib may improve clinical benefit with a manageable safety profile in this pt population. Aims: CITADEL-102 (NCT03039114) is an open-label, phase 1, dose-finding study that investigated safety and efficacy of parsaclisib in combination with bendamustine + obinutuzumab in pts with R/R FL following rituximabcontaining regimens. Methods: Pts enrolled were ≥18 years with histologically confirmed CD20-positive FL, R/R to any prior rituximabcontaining regimen, ECOG PS 0-2, ≥1 measurable lesion, and ≤4 prior therapies. Pts received parsaclisib 20 mg orally once daily (QD) for 8 weeks then 20 mg once weekly (QW);bendamustine 90 mg/m2 infusion on days 1 and 2 of cycles 1-6;and obinutuzumab 1000 mg infusion on days 1, 8, and 15 of cycle 1, and day 1 of cycles 2-6, and on every second cycle of cycles 8-30 in pts having complete response/complete metabolic response (CR/CMR), partial response/partial metabolic response (PR/PMR), or stable disease/no metabolic response. Part 1 (safety run-in) used a 3+3 design with dose de-escalation to identify the maximum tolerated dose (MTD) of parsaclisib in combination with bendamustine + obinutuzumab. In Part 2 (dose expansion), the safety and efficacy of this combination were further evaluated. The primary study endpoint was safety and tolerability;secondary endpoints included efficacy outcomes (ORR, DOR, PFS, and OS). Results: A total of 26 pts were enrolled and treated;median (range) age was 65.0 (44-80) years, 25 (96.2%) had ECOG PS ≤1, 11 (42.3%) had ≥2 prior systemic therapies, and 6 (23.1%) had received prior bendamustine. Median (range) parsaclisib exposure was 10.6 (0.4-32.8) months. Main reasons for treatment discontinuation included adverse events (AEs) (8 pts, 30.8%) and progressive disease (6 pts, 23.1%). All pts experienced treatment-emergent AEs (TEAEs);most common any-grade TEAEs (≥10 pts) were pyrexia (53.8%), neutropenia (50%), diarrhea (46.2%), thrombocytopenia, and nausea (each 38.5%). Grade ≥3 TEAEs were experienced by 88.5% of pts;most common grade ≥3 TEAEs (≥2 pts) were neutropenia (34.6%), febrile neutropenia (23.1%), thrombocytopenia (19.2%), ALT and AST increase (each 11.5%), and diarrhea, neutrophil count decreased, and rash maculopapular (each 7.7%). One of 6 evaluable pts in Part 1 had a DLT of grade 4 QTc elongation. The MTD was not reached, and parsaclisib 20 mg QD for 8 weeks then 20 mg QW was the selected dosage for dose expansion in Part 2. Treatment discontinuation due to TEAEs was 30.8%, 7.7%, and 15.4% for parsaclisib, bendamustine, and obinutuzumab, respectively. One fatal TEAE (COVID-19 pneumonia) occurred. ORR (95% CI) as reported by the investigator was 76.9% (56.4-91.0), with 17 pts (65.4%) achieving CR/CMR and 3 pts (11.5%) achieving PR/PMR as the best overall response. Median DOR, PFS, and OS were not reached. Summary/Conclusion: Parsaclisib in combination with bendamustine + obinutuzumab appears to have a manageable safety profile and demonstrated promising efficacy in pts with R/R FL.

Glofitamab Plus R-CHOP Induces High Response Rates with Minimal Cytokine Release Syndrome (CRS) in Patients (pts) with Relapsed/Refractory (R/R) Non-Hodgkin Lymphoma (NHL) and Previously Untreated (1L) Diffuse Large B-Cell Lymphoma (DLBCL): Preliminary Results from a Dose-Escalation and Safety Run-in Phase Ib Study

Background: Over a third of pts with 1L DLBCL do not respond to, or relapse after, rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP;[Sarkozy and Sehn. Ann Lymphoma 2019]). Despite recent advances, pts with R/R NHL have limited curative options. Glofitamab (Glofit) is a novel, T-cell-engaging bispecific antibody with a 2:1 molecular configuration that allows bivalent binding to CD20 on B cells and monovalent binding to CD3 on T cells. Unlike other CD20xCD3 bispecific antibodies, this format uniquely enables combination with anti-CD20 antibodies, including rituximab. Glofit monotherapy induces high response rates in R/R B-cell NHL (Hutchings et al. J Clin Oncol 2021). We present results of the ongoing NP40126 study (NCT03467373), designed to assess the feasibility and safety of Glofit + R-CHOP in R/R NHL (dose-escalation phase) and 1L DLBCL (safety run-in phase). Methods: R/R NHL dose-escalation: Pts (Eastern Cooperative Oncology Group performance status [ECOG PS] 0-2) received increasing Glofit doses in separate cohorts (70µg, 1800µg, 10mg and 30mg) plus standard R-CHOP for 6-8 cycles (each 21-day). To mitigate CRS risk, R- or obinutuzumab (G)-CHOP was given in Cycle (C)1, with the aim of tumor debulking. Glofit was given from C2 onwards. For 70µg and 1800µg cohorts, fixed-dose Glofit was given on C2 Day (D)8 and onwards. For 10mg and 30mg cohorts, step-up dosing was used to further mitigate CRS risk (2.5mg C2D8, 10mg C2D15, target dose C3D8 and onwards). Optional Glofit maintenance was permitted (every 2 months for <2 years;dose-escalation phase only). 1L DLBCL safety run-in: Pts (ECOG PS 0-3) received Glofit 30mg plus standard R-CHOP for 6-8 cycles (each 21-day). Pts received R-CHOP in C1;Glofit step-up dosing began in C2 (2.5mg C2D8, 10mg C2D15, 30mg C3D8 and onwards). Response rates were assessed by PET-CT (Lugano criteria;[Cheson et al. J Clin Oncol 2014]). CRS events were graded by ASTCT criteria [Lee et al. Biol Blood Marrow Transplant 2019]. Results: R/R NHL dose-escalation: At data cut-off (June 10, 2021), 31 pts (23 follicular lymphoma [FL];6 transformed FL;1 marginal-zone lymphoma;1 mantle-cell lymphoma) had received Glofit with R/G-CHOP. Median age was 62 years, median prior lines of therapy was 2 (range: 1-5). In efficacy-evaluable pts (n=31), after a median 9.0 months' (range: 0-29) follow-up, the overall response rate (ORR) was 90% (n=28) and complete response rate (CRR) was 77% (n=24). Median duration of response was not reached. The Figure shows change in tumor size. Grade (Gr) ≥3 adverse events (AEs) occurred in 28 (90%) pts, serious AEs in 21 (68%) pts and CRS in 17 (55%) pts (mostly low grade;majority after the first 2.5mg Glofit dose;Table). One (3%) pt had a Gr 5 AE (COVID-19 pneumonia not related to study treatment). AEs led to Glofit dose modification/interruption in 2 (6%) pts and Glofit withdrawal in 1 (3%) pt. Neurologic AEs (NAEs) occurred in 20 (65%) pts: Gr 1-2 (16 pts, 52%);Gr 3 (4 pts, 13%). Immune effector cell-associated neurotoxicity syndrome (ICANS)-like AEs were uncommon;a serious AE was reported in 1 pt only (Gr 3 epilepsy during the maintenance phase;resolved in 3 days). Neutropenia occurred in 24 (77%) pts. Median dose intensity was 100% for all R-CHOP components. 1L DLBCL safety run-in: At data cut-off, 13 pts were enrolled (safety population);of these, 4 pts received Glofit 30mg with R-CHOP and were efficacy-evaluable. Median age was 68 years, all pts had Ann Arbor Stage 3/4 disease. At interim assessment (C3), CRR was 100% (4/4). Of 13 pts, 1 (8%) had a CRS event (Gr 1 with fever only) after the first 2.5mg Glofit dose;no other CRS events observed. Gr ≥3 AEs occurred in 8 (62%) pts and Gr ≥3 AEs related to Glofit in 1 (8%) pt only. One (8%) pt had a serious AE and 1 (8%) pt had a Gr 5 AE (infusion-related reaction related to rituximab on C1D1). No AEs led to Glofit or R-CHOP dose interruptions. NAEs occurred in 3 (23%) pts (all Gr 1-2;none were ICANS-like). Neutropenia occurred in 6 (46%) pts. Median dose intensity was 10 % for all R-CHOP components. Conclusions: Initial data show that Glofit + R-CHOP has tolerable safety in R/R NHL and 1L DLBCL. R-CHOP dose intensity was maintained in all pts. The very low CRS rate and no neurotoxicity in 1L DLBCL may render Glofit particularly suitable for the outpatient setting without the need for hospitalization. Updated data, including end-of-treatment responses from the 1L DLBCL safety run-in phase, will be presented.

Glofitamab (Glofit) in Combination with Polatuzumab Vedotin (Pola): Phase Ib/II Preliminary Data Support Manageable Safety and Encouraging Efficacy in Relapsed/Refractory (R/R) Diffuse Large B-Cell Lymphoma (DLBCL)

Background: Glofit is a novel, CD20xCD3 T-cell-engaging bispecific antibody that provides monovalent binding to CD3 on T cells and bivalent binding to CD20 on B cells. As monotherapy, Glofit has shown promising response rates with manageable safety in R/R B-cell non-Hodgkin lymphoma (B-NHL) patients (pts;[Carlo-Stella et al. EHA 2021]). Because of their distinct and complementary mechanism of action, there is a rationale for combining Glofit with the anti-CD79b-targeted antibody-drug conjugate, Pola. NP39488 (NCT03533283) is a Phase Ib/II, open-label, multicenter, dose-escalation (DE) and expansion study evaluating Glofit + Pola or atezolizumab in R/R B-NHL pts (Hutchings et al. ASH 2019). Here, we report preliminary safety and efficacy data for Glofit + Pola in pts with R/R DLBCL during DE and expansion at the recommended Phase II dose (RP2D). Methods: To mitigate the risk of cytokine release syndrome (CRS), a single 1000mg dose of obinutuzumab pre-treatment was administered on Cycle (C) 1 Day (D) 1 alongside step-up dosing (SUD) of Glofit on C1D8 and C1D15. Glofit was subsequently administered at the target dose from C2D1, every 3 weeks up to C12. Pola was administered at 1.8mg/kg on C1D2 and then on D1 of each subsequent cycle up to C6. The primary objective was to establish the RP2D of Glofit in combination with Pola. Results: As of June 10, 2021 (clinical cut-off date [CCOD]), 44 pts were treated with ≥1 cycle;median follow-up was 3.2 months (95% confidence interval: 1.4-3.5). In the first DE cohort, 7 pts had received Glofit at 2.5mg (C1D8)/10mg (C1D15)/10mg (C2D1 onwards) plus Pola. In the second DE cohort, 4 pts received the Glofit target dose of 30mg on C1D15 and this was established as the RP2D. During the expansion phase at RP2D, an additional 34 pts were treated with ≥1 cycle. Of 44 pts, 29 (66%) had histology of R/R DLBCL, 8 (18%) had R/R high-grade B-cell lymphoma (HGBCL;2 HGBCL not otherwise specified;5 double-hit DLBCL;1 triple-hit DLBCL) and 7 (16%) had R/R transformed follicular lymphoma. Pts (61% male) had a median age of 65.5 years (range: 29-82) and received a median of two prior lines (range: 1−5). Twenty-eight (64%) pts were refractory to their last therapy;2 pts had not been treated with Glofit at the CCOD. The most frequent adverse event (AE) was CRS (55%;23/42 pts): Grade (Gr) 1 (n=18);Gr 2 (n=7);no Gr ≥3 CRS events were observed (Lee et al. 2019 ASTCT criteria). Of the 7 pts with Gr 2 CRS, 5 were treated with tocilizumab and fluids for hypotension, and 4 pts were treated with low-flow oxygen due to hypoxia. None of the pts required vasopressors or intensive care unit admission. Gr >3 AEs occurred in 52% (n=23) of pts;most commonly, neutropenia (27%) and anemia (23%). For neurological AEs (NAEs), 13 events were reported in 13 patients (29.5%, 13/44 pts), all were limited to Gr 1−2. The most common NAEs were headache and (11%, 5/44 pts) and insomnia (4.5%, 2/44 pts). No immune effector cell-associated neurotoxicity syndrome-like AEs were reported. Peripheral neuropathy due to Pola was reported in 5/44 pts (11%);all events were Gr 1. Serious AEs occurred in 22 pts (52%);none were CNS or neurological events. One pt experienced fatal COVID-19 pneumonia (not related). Study treatment was discontinued in 2 pts due to AEs (Gr 4 thrombocytopenia, and Gr 3 worsening of pre-existing renal impairment;both events were related to Glofit and Pola). At CCOD 33/44 pts were evaluable for interim (after 2 cycles, 1 target dose of Glofit) or primary (after 8 cycles) response;6/33 pts had experienced progressive disease and discontinued study treatment. Overall response (OR) rate for both dosing cohorts was 73% (24/33) and complete response (CR) rate, per investigator was 51.5% (17/33). Of 7 pts treated with 2.5/10/10mg SUD Glofit, OR and CR rates were both 86% (6/7);durable responses at ≥6 months post-end of treatment were observed. Of 26 pts treated with 2.5/10/30 mg SUD Glofit, OR rate was 73% (19/26) and CR rate was 46% (12/26);11.5% (3/26) pts had stable disease after 2 cycles of therapy. Duration of response and time on study by dosing cohort is shown in Figure. Biomarker and pharmacokinetic data will be provided. Conclusions: Glofit in combination with Pola showed tolerable safety and encouraging preliminary efficacy in R/R DLBCL pts. CRS and NAEs were limited to Gr 1 or 2, no new safety signals were detected for this combination, and the safety profile was consistent with that of the individual drugs. Updated data will be presented.
