Abstract
Polycythemia vera (PV) is a myeloproliferative neoplasm characterized by unregulated red blood cell production resulting in elevated hemoglobin and/or hematocrit levels. Patients often have symptoms such as fatigue, pruritus, and painful splenomegaly, but are also at risk of thrombosis, both venous and arterial. Ruxolitinib, a selective Janus kinase inhibitor, is approved by the US Food and Drug Administration as second-line cytoreductive treatment after intolerance or inadequate response to hydroxyurea. Although ruxolitinib has been widely used in this setting, limited data exist in the literature on ruxolitinib treatment patterns and outcomes among patients with PV in routine clinical practice. We report a retrospective, observational, cohort study of patients treated for PV with ruxolitinib across three US centers (academic and regional practice) from December 2014-December 2019. The study included 69 patients, with a median follow-up duration of 3.7 years (95% CI, 2.9-4.4). Our data demonstrate very high rates of hematocrit control (88% of patients by three months and 89% by six months); few patients required dose adjustments or suspension. No arterial thromboses were observed; however, the follow-up duration does not allow for the generation of meaningful conclusions from this. Three patients had thrombotic events; one was in the setting of a second malignancy, one post-operative, and a third related to prolonged immobility. We also found that 28% of patients initiated ruxolitinib as a result of poorly controlled platelet counts, second only to hydroxyurea intolerance (46%) as a reason to start therapy. In clinical practice, ruxolitinib continues to be effective in controlling hematocrit levels after three and six months of treatment in patients and is associated with low thrombotic risk.

Abstract
ABSTRACT Teclistamab, a B-cell maturation antigen (BCMA)- and CD3-targeting bispecific antibody, is an effective novel treatment for relapsed/refractory multiple myeloma (R/RMM), but efficacy in patients exposed to BCMA-directed therapies and mechanisms of resistance have yet to be fully delineated. We conducted a real-world retrospective study of commercial teclistamab, capturing both clinical outcomes and immune correlates of treatment response in a cohort of patients (n = 52) with advanced R/RMM. Teclistamab was highly effective with an overall response rate (ORR) of 64%, including an ORR of 50% for patients with prior anti-BCMA therapy. Pretreatment plasma cell BCMA expression levels had no bearing on response. However, comprehensive pretreatment immune profiling identified that effector CD8+ T-cell populations were associated with response to therapy and a regulatory T-cell population associated with nonresponse, indicating a contribution of immune status in outcomes with potential utility as a biomarker signature to guide patient management.

Abstract
Medication‐related osteonecrosis of the jaw (MRONJ) is a rare but serious drug‐related adverse event. To identify pharmacogenomic markers of MRONJ associated with bisphosphonate therapy, we conducted a genomewide association study (GWAS) meta‐analysis followed by functional analysis of 5,008 individuals of European ancestry treated with bisphosphonates, which includes the largest number of MRONJ cases to date (444 cases and 4,564 controls). Discovery GWAS was performed in randomly selected 70% of the patients with cancer and replication GWAS was performed in the remaining 30% of the patients with cancer treated with intravenous bisphosphonates followed by meta‐analysis of all 3,639 patients with cancer. GWAS was also performed in 1,369 patients with osteoporosis treated with oral bisphosphonates. The lead single‐nucleotide polymorphism (SNP), rs2736308 on chromosome 8, was associated with an increased risk of MRONJ with an odds ratio (OR) of 2.71 and 95% confidence interval (CI) of 1.90–3.86 (P = 3.57*10−8) in the meta‐analysis of patients with cancer. This SNP was validated in the MRONJ GWAS in patients with osteoporosis (OR: 2.82, 95% CI: 1.55–4.09, P = 6.84*10−4). The meta‐analysis combining patients with cancer and patients with osteoporosis yielded the same lead SNP rs2736308 on chromosome 8 as the top SNP (OR: 2.74, 95% CI: 2.09–3.39, P = 9.65*10−11). This locus is associated with regulation of the BLK, CTSB, and FDFT1 genes, which had been associated with bone mineral density. FDFT1 encodes a membrane‐associated enzyme, which is implicated in the bisphosphonate pathway. This study provides insights into the potential mechanism of MRONJ.

Abstract
7526 Background: Cardiovascular side effects (CVSEs: atrial fibrillation, hypertension, etc.) are common in patients with chronic lymphocytic leukemia (CLL) treated with ibrutinib and often lead to dose reductions or discontinuation. However, the etiology of ibrutinib related CVSEs has not been elucidated. This study sought to interrogate the association between ibrutinib related CVSEs and polymorphisms in genes of the Bruton Tyrosine Kinase (BTK) signaling pathway (identified through Ingenuity Pathway Analysis) Methods: Newly diagnosed and relapsed patients with CLL who underwent treatment with ibrutinib between December 2019 and November 2020 at Levine Cancer Institute were identified. Buccal swabs were collected through an IRB approved specimen collection protocol. Data extraction included: demographics, CLL stage, cytogenetics, previous treatments, ibrutinib start dates and dose, drug related SEs, and other medications. DNA isolated from buccal swabs was genotyped for 40 single nucleotide polymorphisms (SNPs) in GATA4, SGK1, KCNQ1, KCNA4, NPPA and SCN5A genes using a custom NGS panel. Logistic regression analysis evaluated the association between SNPs and CVSEs. Results: In 50 evaluable patients, the median age was 71 years (range:48-90) and 50% received frontline ibrutinib monotherapy. CVSEs occurred in 20% of patients (n=10). In univariate analysis, 4 SNPs in 3 genes were significantly associated with CVSEs (Table). Because the genes were in the same pathway, a genetic risk score was developed which indicated that patients with at least 2 SNPs had a 12-fold increase in risk of CVSEs (Table). Conclusions: Our findings provide insights into the genetic determinants of ibrutinib related CVSEs. If replicated in a larger study, this will facilitate utility of pharmacogenetic testing (for GATA4, KCNQ1 and KCNA5 polymorphisms ) as a clinical tool to individualize ibrutinib treatment.[Table: see text]

Abstract
The approval of letermovir provided a new option for cytomegalovirus (CMV) prophylaxis in CMV seropositive allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients. Data are limited on the use of letermovir for the treatment of CMV infection. We performed a single-center retrospective review of allo-HSCT recipients who received letermovir off-label for treatment of CMV infection (CMV DNAemia and CMV disease) from November 2017 until November 2019. Fifteen patients were included, 14 of which received letermovir for treatment of CMV DNAemia. The median duration from transplant to CMV DNAemia was 41 days and median duration of letermovir therapy was 53 days (IQR, 43-59). Median time to first undetectable CMV viral load from the start of letermovir was 16 days (IQR, 13-21). No significant correlation was noted between the time to CMV DNA clearance and either CMV DNA at the time of starting letermovir (r = -.12, 95% CI: -0.63-0.46; P = .69) or CMV DNA peak (r = .04, 95% CI: -0.51-0.58, P = .87). Three patients had late reactivation of CMV after completion of letermovir (20%) after 87 days (IQR, 68-103) of therapy cessation. Clinical failure or treatment intolerance occurred in two patients (14%). One patient failed to achieve an undetectable viral load. In another patient, letermovir was discontinued due to documented therapy-related thrombocytopenia. Our analysis suggests that letermovir might have a potential role for the treatment of CMV infection in select patients with contraindication or intolerance to more validated therapies.

Abstract
INTRODUCTION Intravenous daratumumab has shown unprecedented anti-myeloma activity when used as a single agent or in combination with other myeloma therapies. Recently, a subcutaneous formulation of daratumumab was approved for use in both the United States and European Union based on data which showed shorter infusion times and decreased rate of infusion reactions while maintaining non-inferior efficacy. AREAS COVERED We cover the physiology behind subcutaneous daratumumab and summarize the relevant clinical data with a particular focus on the pharmacokinetics, pharmacodynamics, safety, and clinical efficacy. Articles used to generate this review were obtained by searching pubmed (https://pubmed.ncbi.nlm.nih.gov/) with the search terms 'subcutaneous daratumumab' and 'daratumumab hyaluronidase'. EXPERT OPINION Subcutaneous daratumumab is associated with lower risk of infusion reactions and decreased administration time while maintaining non-inferior efficacy. We support the use of subcutaneous daratumumab for all approved indications and for investigational use moving forward.

Abstract
8522 Background: CDI is the primary cause of infectious diarrhea in immunocompromised patients including those undergoing autologous stem cell transplant (SCT). Given the key role of gut microbiome and its interaction with host immune system, we investigated whether polymorphisms in innate immunity genes (identified through Ingenuity Pathway Analysis) were associated with CDI. Methods: We queried our database to identify MM patients who underwent an autologous SCT between April 2015-June 2019. Patients who had their buccal swabs collected through an IRB approved specimen collection protocol were included herein. Data were collected on age, conditioning regimen, CDI diagnosis, time from admission until CDI diagnosis, absolute neutrophil count (ANC) at time of CDI diagnosis, and antibiotic prophylaxis. Genomic DNA was extracted from buccal swabs and genotyped for 62 single nucleotide polymorphisms (SNPs) in ASPH , RLBP1L1, ATP7B, IL-8, FAK, TNFRSF14, CTH, TLR and IL-4. Univariate and multivariate logistic regression analyses were performed to assess association between CDI and presence of SNPs in these genes. Results: A total of 83 patients were identified (25 cases and 58 controls). Baseline characteristics were comparable between two groups. Median age was 67 years (range: 50-79). All patients received high dose melphalan as conditioning, and the same antibiotic prophylaxis during peri-transplant period. Median time from hospitalization until CDI diagnosis was 10 days (IQR:9 days), and median ANC was 0.7/mL (IQR:1.6/mL). Two SNPs (rs2227307 T > G in IL-8 and rs2234167 G > A in TNFRSF14) were significantly associated with CDI risk in both univariate and multivariate logistic regression analyses (Table). Conclusions: Our findings suggest that rs227307G (in IL-8) and rs2234167A (in TNFRSF14) alleles are potential risk factors for CDI after autologous SCT. Our findings, if validated in a larger cohort, would support genetic testing as a screening tool to identify patients who might benefit from prophylaxis against CDI. [Table: see text]

Abstract
e19504 Background: IFIs are one of the most detrimental complications of profound and prolonged neutropenia post-allogeneic SCT. Prophylaxis with broad spectrum azole antifungals has become standard of care given favorable outcomes associated with their use in this setting. Nonetheless, the choice of antifungal agent varies between institutions due to absence of consensus guidelines in patients undergoing haploidentical SCT. Methods: Non-interventional retrospective study seeking to compare efficacy of fluconazole vs. voriconazole for prevention of IFI post haploidentical SCT for hematologic malignancies. SCT databases at two academic insitutions (one uses fluconazole and other uses voriconazole) were queried to identify patients who underwent allogeneic SCT from April 2012 until March 2018, and received prophlaxis with either voriconazole (group I) or fluconazole (group II). Patients with intent to start prophylaxis with fluconazole or voriconazole were included, even if antifungal agent was changed later. Primary endpoint was cumulative incidence of breakthrough IFIs (based on MSG criteria) on day +100 and +180. Fisher exact test was used to compare rates of breakthrough IFIs between two cohorts. Secondary endpoint was overal survival (OS). Kaplan Meiers analysis was performed to compare OS on day +180 and 1-year post SCT. Results: The cohort included 141 patients (group I: 75 and group II: 66). Percentage of patients who underwent transplant for leukemia was higher in group I compared to group II (77.3% vs. 56.1%, p < 0.001). A haploidentical SCT was performed in 62.7% of patients in group I compared to 100% in group II (p < 0.001). All patients received non-myeloablative conditioning. There was no statistically significant difference in rates of IFIs between two groups on day +100 (0% in I vs. 4.5% in II, p = 0.9) and +180 (1.4% vs. 4.6%, p = 0.2). A significant difference in OS was noted on day +180 and at 1-year in univariate analysis (Table). Conclusions: Our findings suggest that prophylactic use of either voriconazole or fluconazole after haploidentical SCT is associated with low rates of IFIs. However, survival data favored voriconazole over fluconazole. [Table: see text]

Abstract
11592 Background: SCMs are prescribed based on symptom burden, but response is variable, possibly due to PGx. We investigated the association between symptom burden, SCM prescribing, and frequency of SCMs with PGx evidence. Methods: Cancer pts ≥ 18 years old and completing electronic distress screening within 90 days of intake between 1/1/2017-12/31/2017 were included. Anxiety was measured using Generalized Anxiety Disorder 2-item (0-6) and depression using Patient Health Questionnaire-2 (0-6). Fatigue, nausea, neuropathy, pain and sleep were measured on a 0-10 scale. SCM prescribing within 90 days of intake was documented. Logistic regression compared symptom scores and SCM prescribing. Receiver Operating Characteristics analysis estimated sensitivity/specificity. Optimal symptom thresholds were selected according to Youden’s J statistic. SCMs with PGx evidence level A or B (according to Clinical Pharmacogenetics Implementation Consortium) were summarized. Results: Of 6985 pts, 65% were female, 75% Caucasian, 20% African American and median age was 60. 49% reported ≥ 1 severe symptom, which correlated with SCM prescribing (p < 0.001). 3208 (46%) were prescribed SCM(s), mainly for pain (69%) or nausea (46%). Of these, 2759 (86%) received ≥ 1 SCM with PGx evidence and 2695 (84%) received a SCM metabolized by CYP2D6 - hydrocodone (47%), ondansetron (41%), and oxycodone (28%). Based on reported CYP2D6 allele frequencies conferring altered metabolism (~20%), 539 of the 2695 pts may have altered drug response. Threshold scores for each symptom are summarized in the table. Fatigue and nausea were not associated with SCM prescribing. Conclusions: Symptom burden is high in cancer pts and correlates with SCM prescribing. Many SCMs have PGx evidence, suggesting preemptive testing, particularly for CYP2D6, may have broad applicability in this population.[Table: see text]

Abstract
Therapeutic concentrations of voriconazole in invasive fungal infections (IFIs) are ensured using a drug monitoring approach, which relies on attainment of steady-state pharmacokinetics. For voriconazole, time to reach steady state can vary from 5-7 days, not optimal for critically ill patients. We developed a population pharmacokinetic/pharmacodynamic model-based approach to predict doses that can maximize the net benefit (probability of efficacy-probability of adverse events) and ensure therapeutic concentrations, early on during treatment. The label-recommended 200 mg voriconazole dose resulted in attainment of targeted concentrations in ≥80% patients in the case of Candida spp. infections, as compared to only 40-50% patients, with net benefit ranging from 5.8-61.8%, in the case of Aspergillus spp. infections. Voriconazole doses of 300-600 mg were found to maximize the net benefit up to 51-66.7%, depending on the clinical phenotype (due to CYP2C19 status and pantoprazole use) of the patient and type of Aspergillus infection.

Abstract
Neurofibromatosis type 1 (NF1) is caused by mutations in the NF1 gene encoding neurofibromin, which negatively regulates Ras signaling. NF1 patients have an increased risk of developing early onset breast cancer, however, the association between NF1 and high grade serous ovarian cancer (HGSOC) is unclear. Since most NF1-related tumors exhibit early biallelic inactivation of NF1, we evaluated the evolution of genetic alterations in HGSOC in an NF1 patient. Somatic variation analysis of whole exome sequencing of tumor samples from both ovaries and a peritoneal metastasis showed a clonal lineage originating from an ancestral clone within the left adnexa, which exhibited copy number (CN) loss of heterozygosity (LOH) in the region of chromosome 17 containing TP53, NF1, and BRCA1 and mutation of the other TP53 allele. This event led to biallelic inactivation of NF1 and TP53 and LOH for the BRCA1 germline mutation. Subsequent CN alterations were found in the dominant tumor clone in the left ovary and nearly 100% of tumor at other sites. Neurofibromin modeling studies suggested that the germline NF1 mutation could potentially alter protein function. These results demonstrate early, biallelic inactivation of neurofibromin in HGSOC and highlight the potential of targeting RAS signaling in NF1 patients.

Abstract
119 Background: PM can improve the quality of life and survival for cancer patients (pts); however, the demand for PM challenges providers with delayed follow ups resulting in less than one-third of pts achieving significant pain improvement between clinic visits. Engaging pharmacists in the provision of PM may help improve pain management in cancer pts. Methods: Adult cancer pts starting a new pain regimen or requiring changes to an existing regimen at baseline were referred for pharmacy follow up in 3-7 days (assessment #1). The pharmacist evaluated each pt using the Edmonton Symptom Assessment Scale and recommended changes to the referring PM provider, prompting a 2nd follow up in 3-7 days (assessment #2). If no changes were required, pts continued therapy and returned for the final clinic visit (day 28 +/- 7). The primary endpoint was the proportion of pts achieving significant pain improvement (≥ 2-point decrease in pain score on a scale of 0-10) from baseline to final visit, which was compared to historical controls using Fisher’s Exact test. Changes in pain severity from baseline to final visit were compared using Generalized McNemar’s test, and descriptive statistics were used to describe characteristics at assessment #1. Results: Of 102 pts evaluable for the primary endpoint, 76% had stage IV disease, 58% were female, and median age was 57 yrs. Significantly more pts achieved pain improvement from baseline to final visit compared to historical controls (49% v 30%; P < 0.001). Changes in pain severity from baseline to final visit are described in the table. At assessment #1, 70% of pts required an intervention, primarily due to uncontrolled pain (72%), side effects (26%), and/or lack of response to non-pain medications (22%). The most common types of interventions were dose adjustments (62%), education (36%), and/or adding a new medication (30%). Over 90% of recommendations were accepted by the referring PM provider. The median time of assessment was 15 mins. Conclusions: Routine inclusion of pharmacists in the outpatient PM interdisciplinary team improves the effectiveness of pain management. [Table: see text]

Abstract
BACKGROUND AND PURPOSE To review and explain some of the characteristics of synergistic divergence and compare the surgical effect on each of those characteristics. METHODS OF STUDY Three patients demonstrating findings characteristic of synergistic divergence, two bilateral and one unilateral, are reported. Surgery consisted of denervation extirpation of the lateral rectus muscle along with resection of the medial rectus muscle of the affected eye or supramaximal recession of the lateral rectus muscle and resection of the antagonist medial rectus muscle of the affected eye. RESULTS The simultaneous abduction and the abnormal head posture responded well to surgery. The exotropia was reduced. The deficient adduction, the total absence of active abduction and the infraduction of the synkinetically abducting eye remained unchanged. CONCLUSIONS Synergistic divergence is a severe exotropic form of Duane's Syndrome where the feature of simultaneous abduction is the most striking. To date, no surgical procedure leads to satisfactory results on all the characteristics of synergistic divergence. Although some important features can be satisfactorily improved, some others do not respond to current surgical techniques.

Abstract
We determined the ability to appreciate the direction of a skin pull caused by a moving pin that was glued to the forearm skin. A majority of the subjects were able to tell the direction of pin movements with an excursion of 0.13 mm (>/=66% correct responses, p<0.05). Local skin anaesthesia showed that stretch sensitive receptors located over 15 mm in front and behind the pin correctly signalled the direction of these minute skin pulls. It was concluded that information about patterns of skin stretch is an important component of the somatosensory system that may contribute not only to kinaesthetic, but also to cutaneous sensations.
