RESUMEN

CD19-directed chimerical antigen receptor T-cell (CAR-T) products have gained US Food and Drug Administration approval for systemic large B-cell lymphoma. Because of concerns about potential immune cell-associated neurotoxicity syndrome (ICANS), patients with primary central nervous system (CNS) lymphoma (PCNSL) were excluded from all pivotal CAR-T studies. We conducted a phase 1/2 clinical trial of tisagenlecleucel in a highly refractory patients with PCNSL and significant unmet medical need. Here, we present results of 12 relapsed patients with PCNSL who were treated with tisagenlecleucel and followed for a median time of 12.2 months (range, 3.64-23.5). Grade 1 cytokine release syndrome was observed in 7/12 patients (58.3%), low-grade ICANS in 5/12 (41.6%) patients, and only 1 patient experienced grade 3 ICANS. Seven of 12 patients (58.3%) demonstrated response, including a complete response in 6/12 patients (50%). There were no treatment-related deaths. Three patients had ongoing complete remission at data cutoff. Tisagenlecleucel expanded in the peripheral blood and trafficked to the CNS. Exploratory analysis identified T-cell, CAR T, and macrophage gene signatures in cerebrospinal fluid following infusion when compared with baseline. Overall, tisagenlecleucel was well tolerated and resulted in a sustained remission in 3/7 (42.9%) of initial responders. These data suggest that tisagenlecleucel is safe and effective in this highly refractory patient population. This trial was registered at www.clinicaltrials.gov as #NCT02445248.

RESUMEN

Chronic graft-versus-host disease (GVHD) is one of most common complications following allogeneic hematopoietic cell transplantation (HCT) and the most significant contributor to morbidity and nonrelapse mortality. The physical burdens and psychosocial difficulties of these patients have not been described systematically. An exploration into the rates and correlates of mood and quality of life (QOL) in patients with chronic GVHD is necessary to develop a clinically relevant, evidence-based intervention to promote well-being. From July 2015 to July 2017, adult allogeneic HCT survivors with established moderate to severe chronic GVHD (N = 52) enrolled in a prospective, longitudinal study at a tertiary academic center. We examined the rates and correlates of depression and anxiety symptoms (Hospital Anxiety and Depression Scale) and explored whether constructs including coping strategies (Coping Inventory for Stressful Situations), symptom burden (Lee Symptom Assessment Scale), physical functioning (Human Activity Profile), and perceived social support (Medical Outcomes Study Social Support Survey) predicted QOL trajectory over time (Functional Assessment of Cancer Therapy-Bone Marrow Transplant) at the baseline, 3-month, and 6-month follow-up. Analyses adjusted for age, sex, chronic GVHD severity, and time since chronic GVHD diagnosis. At the baseline, 3-month, and 6-month follow-up, 32.7%, 31.1%, and 37.8% of patients reported clinically significant depression symptoms, and 30.8%, 20.0%, and 36.4% reported clinically elevated anxiety symptoms, respectively. Adjusting for covariates, greater use of negative emotion-oriented coping (ß = 0.20, P = .002), less use of task-oriented coping (ß = -0.10, P = .021), worse physical functioning (ß = -0.07, P = .004), and higher symptom burden (ß = 0.07, P = .002) were independently associated with depression symptoms at baseline. Greater use of negative emotion-oriented coping (ß = 0.28, P < .001) and worse physical functioning (ß = -0.05, P = .034) were independently associated with anxiety at baseline. Patients who used more negative emotion-oriented coping (ß = -0.58, P = .035), had less task-oriented (ß = 0.40, P = .028) and social diversion-oriented coping (ß = 0.35, P = .039), and had higher symptom burden (ß = -0.30, P = .001), worse physical functioning (ß = 0.32, P < .001), and lower perceived social support (ß = 6.47, P = .003) at baseline reported poorer QOL over time. The unmet physical and psychosocial needs of patients with chronic GVHD are substantial and warrant investigation into evidence-based interventions that may improve QOL and mood by targeting modifiable psychosocial constructs identified in this study.

RESUMEN

We conducted a phase I study of brentuximab vedotin (BV), an antibody-drug conjugate targeting CD30, for the treatment of steroid-refractory chronic graft-versus-host disease (cGVHD). A modified 3 + 3 study design was used with the primary endpoint to determine the maximum tolerated dose of BV in this population. Escalating doses of BV were planned, starting with .6 mg/kg every 3 weeks (dose level 0) and increasing by .3 mg/kg per dose level. BV was administered in 21-day cycles for up to 16 cycles of therapy. Nineteen patients were enrolled on the study, with 2 withdrawing consent before dosing. The median number of cycles of therapy was 4 (range, 1 to 16). Reasons for stopping therapy prematurely included toxicities (n = 9), patient decision (n = 3), lack of response (n = 2), and death (n = 1). There were 2 dose-limiting toxicities observed: posterior reversible encephalopathy syndrome (cohort 4, grade 3) and sepsis (cohort 4, grade 4). The maximum tolerated dose was not reached because the trial was prematurely closed due to toxicity. Seven patients (41%) developed grade 3 or 4 adverse events that were attributed to therapy, including 4 patients who developed moderate or severe peripheral neuropathy that led to cessation of treatment in each case. According to National Institutes of Health cGVHD response criteria, 8 patients (47%) experienced a partial response, whereas 9 patients (53%) had a lack of response. There were no complete responses observed. Eleven patients (65%) were able to decrease their systemic corticosteroid dose by ≥50% by 6 months after initiation of BV, including 3 patients who were able to stop corticosteroids completely. The median soluble CD30 level before therapy was 61.5 ng/mL (range, 7.8 to 474.9); however, we did not observe any association between soluble CD30 level and cGVHD severity at enrollment or clinical responses to BV. In conclusion, BV may have activity in treatment of steroid-refractory cGVHD, yet its use is limited by treatment-emergent toxicities, including peripheral neuropathy. Continued efforts to investigate targeted approaches to cGVHD that do not cause broad immunosuppression are needed.

RESUMEN

BACKGROUND: Although sexual dysfunction is common after hematopoietic stem cell transplantation (HCT), interventions to address sexual function are lacking. METHODS: We conducted a pilot study to assess the feasibility and preliminary efficacy of a multimodal intervention to address sexual dysfunction in allogeneic HCT survivors. Transplant clinicians screened HCT survivors ≥3 months post-HCT for sexual dysfunction causing distress. Those who screened positive attended monthly visits with a trained transplant clinician who: 1) performed an assessment of the causes of sexual dysfunction; 2) educated and empowered the patient to address his or her sexual concerns; and 3) implemented therapeutic interventions targeting the patient's needs. Feasibility was defined as having approximately 75% of patients who screened positive agreeing to participate and 80% attending at least 2 intervention visits. We administered the Patient-Reported Outcomes Measurement Information System (PROMIS) sexual function and satisfaction measure, the Functional Assessment of Cancer Therapy-Bone Marrow Transplant (FACT-BMT), and the Hospital Anxiety and Depression Scale (HADS) to evaluate sexual function, quality of life (QOL), and mood, respectively, at baseline and 6 months postintervention. RESULTS: Approximately 33.1% of patients (50 of 151 patients) screened positive for sexual dysfunction causing distress and 94.0% (47 of 50 patients) agreed to participate, with 100% attending 2 intervention visits. Participants reported improvements in satisfaction (P<.0001) and interest in sex (P<.0001), as well as orgasm (P<.0001), erectile function (P<.0001), vaginal lubrication (P = .0001), and vaginal discomfort (P = .0005). At baseline, approximately 32.6% of participants were not sexually active, compared with 6.5% after the intervention (P = .0005). Participants reported improvement in their QOL (P<.0001), depression (P = .0002), and anxiety (P = .0019). CONCLUSIONS: A multimodal intervention to address sexual dysfunction integrated within the transplant clinic is feasible with encouraging preliminary efficacy for improving sexual function, QOL, and mood in HCT survivors.

RESUMEN

Clofarabine has potent antileukemia activity and its inclusion in reduced-intensity conditioning (RIC) allogeneic hematopoietic stem cell transplantation (HSCT) for acute leukemia could potentially improve outcomes. We conducted a phase II study of busulfan (.8 mg/kg i.v. twice daily on days -5, -4, -3, and -2) with clofarabine (40 mg/m(2) i.v. daily on days -5, -4, -3, and -2) conditioning before allogeneic 8/8 HLA-matched related or unrelated HSCT. The primary endpoint was donor neutrophil engraftment by day +40. Secondary endpoints included nonrelapse mortality (NRM), acute and chronic graft-versus-host disease (GVHD), progression-free survival (PFS), and overall survival (OS). Thirty-four patients (acute myeloid leukemia [AML], n = 25; myelodysplastic syndromes, n = 5; and acute lymphoid leukemia, n = 4) were enrolled. Day 40+ engraftment with donor chimerism was achieved in 33 of 34 patients with 1 patient dying before count recovery. Day 100 and 1-year NRM were 5.9% (95% confidence interval [CI], 1.0 to 17.4) and 24% (95% CI, 11 to 39), respectively. The 2-year relapse rate was 26% (95% CI, 13 to 42). Cumulative incidences of acute and chronic GVHD were 21% and 44%, respectively. The 2-year PFS was 50% (95% CI, 32 to 65) and OS was 56% (95% CI, 38 to 71). For patients with AML in first complete remission, 2-year PFS and OS were both 82% (95% CI, 55 to 94). RIC with busulfan and clofarabine leads to successful engraftment with acceptable rates of NRM and GVHD.

RESUMEN

Allogeneic hematopoietic cell transplantation (HCT) survivors may benefit from routine screening for post-transplant complications. However, the impact of formal survivorship efforts to promote screening adherence is uncertain. The effect of a formal HCT survivorship program to promote screening adherence was evaluated. We conducted a retrospective analysis of an academic formal HCT survivorship program with primary and specialty consult components. We included patients who underwent allogeneic HCT and were alive and relapse-free 1-year post-HCT. We excluded patients who died <2-year post-HCT or transferred care. We measured screening adherence to cardiovascular, pulmonary, ocular, secondary cancer, and endocrine evaluations. The primary outcome was proportion of patients completing ≥1 evaluation per screening domain prior to 2-year post-HCT. We examined screening adherence during 3 time periods: presurvivorship (2012 to 2014) and 2 postsurvivorship (2016 to 2018 and 2019 to 2021) using multivariate logistic and Cox proportional hazards regression. Four hundred ten patients (2012 to 2014: n = 136, 2016 to 2018: n = 153, 2019 to 2021: n = 121) were included. Compared to the presurvivorship period (16.9%), patients in 2016 to 2018 (47.7%, odds ratio [OR] = 4.9, P < .0001) and 2019 to 2021 (34.7%, OR = 2.7, P = .001) were more likely to complete ≥1 evaluation per screening domain. Except for pulmonary function tests in 2019 to 2021, median time to completion of survivorship evaluations was shorter in the survivorship periods compared to presurvivorship. Patients who completed a formal HCT survivorship consult in 2016 to 2018 and 2019 to 2021 were more likely to complete ≥1 evaluation per screening domain (OR = 5.1, P = .0004). Survivorship consult had similar effect on the primary screening outcome in 2016 to 2018 and 2019 to 2021 (consult × time interaction OR: 2.5, P = .2). However, patients who received a consult in 2019 to 2021 were more likely to complete all screenings (consult × time interaction: OR = 5.7, P = .03). Our HCT survivorship program with primary and specialty components improved screening adherence. Additional studies are needed to evaluate efficacy, dissemination, and implementation of formal HCT survivorship programs.

RESUMEN

PURPOSE OF REVIEW: Posterior approach ptosis repair has made a resurgence over the last decade. The purpose of this review is to examine the history of posterior approach ptosis repair and the events that have led to its current favorable status. RECENT FINDINGS: The evolution of the posterior and anterior approach ptosis surgeries has resulted in two favored techniques for involutional ptosis repair: the Müller muscle-conjunctiva resection (MMCR) and the external levator advancement. Each procedure has strong and prominent proponents in the oculoplastic surgery community. Recently, the MMCR has converted surgeons who have previously favored the external levator advancement. A number of factors have influenced this recent elevation of the MMCR including differing opinions on the cause of involutional ptosis, the mechanism by which the MMCR works, the predictability and speed of the MMCR, and the current reimbursements for ptosis repair by insurance companies. SUMMARY: The recent preference for posterior approach ptosis surgery, in particular the MMCR, is multifactorial. In order to understand the evolution of opinions about the procedure, a historical knowledge of involutional ptosis and ptosis repair is necessary.

RESUMEN

OBJECTIVE: To review the available evidence for the neuroprotective qualities of brimonidine tartrate in optic nerve and retinal injury. METHODS: References for this study were obtained by running a search of the PubMed database using keywords brimonidine, neuroprotection, ischemic optic neuropathy, and alpha2-adrenergic agonists. References focusing on ocular hypertension were excluded. RESULTS: Forty-eight articles addressing 1 of 4 criteria for neuroprotection were included. The literature confirms that brimonidine therapy meets the first 3 criteria for neuroprotection: receptors on its target tissues, adequate penetration into the vitreous and retina at pharmacologic levels, and induction of intracellular changes that enhance neuronal resistance to insults or interrupt apoptosis in animal models. Brimonidine did not meet the final neuroprotective criterion of success in humans. CONCLUSIONS: Experimental evidence has demonstrated that brimonidine is a potential neuroprotective agent. However, to date, clinical trials have failed to translate into similar efficacy in humans.
