Randomized trial of tapas acupressure technique for weight loss maintenance

<p>Abstract</p> <p>Background</p> <p>Obesity is an urgent public health problem, yet only a few clinical trials have systematically tested the efficacy of long-term weight-loss maintenance interventions. This randomized clinical trial tested the efficacy of a novel mind and body technique for weight-loss maintenance.</p> <p>Methods</p> <p>Participants were obese adults who had completed a six-month behavioral weight-loss program prior to randomization. Those who successfully lost weight were randomized into either an experimental weight-loss maintenance intervention, Tapas Acupressure Technique (TAT^®), or a control intervention comprised of social-support group meetings (SS) led by professional facilitators. TAT combines self-applied light pressure to specific acupressure points accompanied by a prescribed sequence of mental steps. Participants in both maintenance conditions attended eight group sessions over six months of active weight loss maintenance intervention, followed by an additional 6 months of no intervention. The main outcome measure was change in weight from the beginning of the weight loss maintenance intervention to 12 months later. Secondary outcomes were change in depression, stress, insomnia, and quality of life. We used analysis of covariance as the primary analysis method. Missing values were replaced using multiple imputation.</p> <p>Results</p> <p>Among 285 randomized participants, 79% were female, mean age was 56 (standard deviation (sd) = 11), mean BMI at randomization was 34 (sd = 5), and mean initial weight loss was 9.8 kg (sd = 5). In the primary outcome model, there was no significant difference in weight regain between the two arms (1.72 kg (se 0.85) weight regain for TAT and 2.96 kg (se 0.96) weight regain for SS, p < 0.097) Tests of between- arm differences for secondary outcomes were also not significant. A secondary analysis showed a significant interaction between treatment and initial weight loss (p < .036), with exploratory <it>post hoc </it>tests showing that greater initial weight loss was associated with more weight regain for SS but less weight regain for TAT.</p> <p>Conclusions</p> <p>The primary analysis showed no significant difference in weight regain between TAT and SS, while secondary and post hoc analyses indicate direction for future research.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov: <a href="http://www.clinicaltrials.gov/ct2/show/NCT00526565">NCT00526565</a></p

Supportive Management of Patients with Advanced Pheochromocytomas and Paragangliomas Receiving PRRT.

Peptide receptor radionuclide therapy (PRRT) is used to treat patients with advanced malignant pheochromocytomas (PCCs) and paragangliomas (PGLs). Patients are at risk of a PRRT-induced catecholamine crisis, and standard guidelines regarding the prevention and management of infusion reactions are lacking. In this case series, the institutional experience of five sequential patients with metastatic PCCs and PGLs receiving PRRT on an outpatient basis is described, of which four had symptomatic tumors and three had a high burden of disease. All patients with symptomatic tumors were treated with preventive management prior to the initiation of PRRT, and no infusion reactions or catecholamine crises were documented. PRRT may be delivered safely on an outpatient basis for patients with metastatic PCCs and PGLs with the involvement of an interdisciplinary team

Initial Safety Results from a Phase II Study of Acalabrutinib Plus RICE Followed By Autologous Hematopoietic Cell Transplantation and/or Acalabrutinib Maintenance Therapy for Patients with Relapsed/Refractory Diffuse Large B-Cell Lymphoma

Background: Patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) often have a poor prognosis despite therapies using second-line chemoimmunotherapy (CIT). Achievement of complete response (CR) with second-line therapy is associated with improved long-term outcomes. Unfortunately, only 25-35% of patients achieve CR with standard CIT regimens alone. The addition of novel targeted agents such as Bruton Tyrosine Kinase inhibitors (BTKi) to second-line therapy may offer improved treatment responses given the importance of B-cell receptor (BCR) signaling in DLBCL. BTK has been shown to be essential for BCR-mediated activation of the NF- κB/Rel family of transcription factors and BCR signaling has been recognized as a key pathway in the pathogenesis of DLBCL. Moreover, NF-κB activity relies upon chronic active BCR signaling in activated B-cell-like DLBCL, which can be potentially blocked by kinase inhibitors targeting BTK. In this study we examine the feasibility and efficacy of adding the BTKi, acalabrutinib (A), to standard second-line therapy to improve disease response in patients with R/R DLBCL. Here we present initial safety and tolerability data for the ongoing study. Study Design and Methods: This is an open-label, prospective phase II trial (NCT03736616). Cohort A is open to R/R DLBCL patients eligible for autologous hematopoietic transplantation (HCT). Cohort B is open to R/R DLBCL patients considered ineligible for autologous HCT. The primary endpoint for cohort A is to estimate the confirmed CR rate (RECIL 2017 criteria) prior to autologous HCT in patients undergoing second-line CIT. The primary endpoint for cohort B is defined as the estimate of one-year progression-free survival in patients undergoing second-line induction and maintenance acalabrutinib therapy. Cohort A receive 2 cycles of standard RICE salvage CIT in combination with acalabrutinib, 100mg BID days 1-21 of a 21-day cycle (RICE+A). After 2 cycles of therapy, patients undergo autologous stem cell mobilization and collection. Patients then receive a 3 rd cycle of RICE in combination with acalabrutinib. PET-CT (PET3) is to be performed on day 15 of cycle 3 to assess response. Patients with CR or partial response (PR) after PET3 proceed to autologous HCT with BEAM conditioning within 28-42 days of PET3. Post-HCT CR patients receive acalabrutinib 100mg BID as maintenance therapy for 12 additional months. Protocol amendment in May 2021 allows for PET assessment (C2D15) prior to autologous stem cell collection (after cycle 3). Cohort B receive 3 cycles of RICE+A in 21-day cycles followed by PET-CT (PET3) on day 15 of cycle 3. Patients without progressive disease at PET3 continue with acalabrutinib maintenance up to 12 additional cycles until disease progression or unacceptable toxicity. Patients demonstrating progressive disease are withdrawn from study treatment but followed for outcomes. Results: Here we report initial safety and tolerability data for the ongoing study with data cutoff July 28, 2021. Twenty-two patients have been screened and 20 patients have received at least 1 cycle of RICE+A. Patient characteristics are shown in Table 1. Fifteen patients (79%) have completed 3 cycles of RICE+A. One patient (5%) discontinued due to an adverse event (AE; recurrent appendicitis), 3 patients (16%) discontinued due to progressive disease, and 1 patient is receiving ongoing RICE+A as of data cutoff. Hematologic AE have been observed in 17 patients (89%) with 74% being Grade 3/4. Amongst these, neutropenia was the most common AE occurring in 47% with all being Grade 3/4, and thrombocytopenia occurring in 32% with all being Grade 3/4. All hematologic AE recovered to baseline or grade 1 in median 7 days. Amongst non-hematologic AE, diarrhea occurred in 21% and 0% were Grade 3/4, nausea 16% with 0% Grade 3/4, and headache in 16% with 0% Grade 3/4. Discontinuation of therapy due to AE occurred in 1 patient (recurrent appendicitis) and dose reduction occurred in 1 patient (Gr 4 neutropenia). Temporary (per protocol) dose holds of A occurred in 9 patients (45%), primarily for cytopenias during concurrent RICE+A. Median duration for dose holds of A was 5.5 days. Conclusion: RICE+A is feasible with manageable primarily hematologic AEs similar to those reported for RICE alone. Enrollment and follow up is ongoing for efficacy endpoints and further toxicity assessment

Initial Efficacy and Safety of Acalabrutinib Plus RICE in Transplant Eligible Patients with Relapsed/Refractory Diffuse Large B-Cell Lymphoma

Background: Patients (pts) with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) undergoing second-line chemoimmunotherapy (2L CIT) often have a poor prognosis with a minority achieving curative outcomes. Achievement of CR with 2L CIT is associated with favorable long-term outcomes in patients consolidated with autologous stem cell transplant (ASCT). Unfortunately, only 25-35% of patients achieve complete response (CR/CR unconfirmed) with RICE CIT (Gisselbrecht 2010). Addition of novel targeted agents such as Bruton Tyrosine Kinase inhibitors (BTKi) to 2L CIT may offer improved treatment responses given the importance of B-cell receptor (BCR) signaling in DLBCL. Here we report the feasibility and efficacy of combining acalabrutinib (acala) 100mg BID with RICE (A-RICE) chemotherapy in ASCT eligible pts with R/R DLBCL. Study Design and Methods: In a single-center, open-label, phase 2 trial (NCT03736616) we evaluate the feasibility, efficacy, and tolerability of combining acala with RICE as 2L CIT in R/R DLBCL pts. There are two study cohorts. Cohort A is open to R/R DLBCL pts who are eligible for 2L CIT followed by ASCT consolidation. Cohort B is open to R/R DLBCL pts considered medically ineligible for ASCT. The primary objective for cohort A is to estimate the confirmed CR rate (RECIL 2017 criteria) of A-RICE prior to HCT. Primary endpoint for cohort A is met if \u3e10 of maximum 24 enrolled patients achieve CR, which allows rejection of the null hypothesis that confirmed CR rate is ≤ 25% if true CR rate is 50% (one-sided α =0.05, power = 85%). The primary endpoint for cohort B is the estimate of one-year progression-free survival in patients undergoing 2L CIT followed by maintenance acala for up to 12 months. Secondary endpoints include overall response rate (ORR), incidence of Grade 3/4 adverse events (AEs), and incidence of serious AEs in both cohorts. Pts in cohort A received 2 cycles of A-RICE in a 21 day cycle. After 2 cycles A-RICE, response assessment via PET-CT (PET2) was completed with responding patients receiving a 3rd cycle of A-RICE followed by stem cell mobilization and collection. PET-CT was performed 14-21 days after day 1 of cycle 3 (PET3) to assess response to 2L CIT. Those patients with CR or partial response (PR) after PET3 proceeded to BEAM conditioned ASCT within 28-42 days of PET3. After hematopoietic recovery, patients may continue acalabrutinib 100mg BID as maintenance therapy for 12 months post ASCT. Minimal residual disease (MRD) is assessed using ctDNA (clonoseq) at time points pre-ASCT, post-ASCT, and during maintenance A. Results: Primary endpoint for Cohort A has been met and is reported here, while Cohort B has not yet met pre-specified enrollment or follow up maturity for efficacy analyses. Safety for both cohorts to date is reported. Twenty-six pts have been enrolled (19 cohort A, 7 cohort B). In Cohort A, 5 pts had refractory DLBCL, 7 pts were GCB, 10 non-GCB. Median age of Cohort A was 58, and median of Cohort B was 75 (Table 1). 19 Cohort A pts received at least 1 cycle of A-RICE, with 16 pts completing 3 cycles. One patient (4%) stopped A-RICE due to AE, 3 patients (13%) discontinued due to progressive disease (PD). All 19 pts in cohort A were considered response evaluable following initiation A-RICE: ORR was 74% (14 pts), with 53% CR (10 pts), 21% PR (4 pts). Thirteen pts (68%) underwent planned consolidative ASCT. See Figure 1 for response data. Safety data for all 26 cohort A and B patients who received at least 1 cycle A-RICE was assessed for the first three cycles of A-RICE. The most common treatment-related AEs were thrombocytopenia (All 50%, Gr 3/4 46%) and neutropenia (Gr 3/4 30%). SAEs were reported in 5 pts with 1 therapy related SAE of neutropenic fever, and 4 treatment unrelated SAEs. Of the 19 efficacy evaluable pts in cohort A, 10 pts interrupted 1 or more doses of acalabrutinib during a A-RICE cycle either due to patient error or protocol specified dose hold related to AE. Conclusions: A-RICE in ASCT eligible pts w/ R/R DLBCL demonstrated CR in 53% of response evaluable patients. Further, we observed a high ORR (74%) and high proportion of pts completing planned ASCT (68%). AEs with A-RICE were consistent with those expected for CIT. A-RICE warrants further investigation in pts w/ R/R DLBCL eligible for 2L CIT with intention to undergo ASCT. Further analyses of cohort A, including ctDNA based MRD dynamics, PFS, and OS are ongoing and will be updated at meeting
