Pharmacogenetic guided versus standard warfarin dosing for routine clinical care with its pharmacoeconomic impact: a randomized controlled clinical trial.

BACKGROUND: Empirical use of pharmacogenetic test(PGT) is advocated for many drugs, and resource-rich setting hospitals are using the same commonly. The clinical translation of pharmacogenetic tests in terms of cost and clinical utility is yet to be examined in hospitals of low middle income countries (LMICs). AIM: The present study assessed the clinical utility of PGT by comparing the pharmacogenetically(PGT) guided- versus standard of care(SOC)- warfarin therapy, including the health economics of the two warfarin therapies. METHODS: An open-label, randomized, controlled clinical trial recruited warfarin-receiving patients in pharmacogenetically(PGT) guided- versus standard of care(SOC)- study arms. Pharmacogenetic analysis of CYP2C9*2(rs1799853), CYP2C9*3(rs1057910) and VKORC1(rs9923231) was performed for patients recruited to the PGT-guided arm. PT(Prothrombin Time)-INR(international normalized ratio) testing and dose titrations were allowed as per routine clinical practice. The primary endpoint was the percent time spent in the therapeutic INR range(TTR) during the 90-day observation period. Secondary endpoints were time to reach therapeutic INR(TRT), the proportion of adverse events, and economic comparison between two modes of therapy in a Markov model built for the commonest warfarin indication- atrial fibrillation. RESULTS: The study enrolled 168 patients, 84 in each arm. Per-protocol analysis showed a significantly high median time spent in therapeutic INR in the genotype-guided arm(42.85%; CI 21.4-66.75) as compared to the SOC arm(8.8%; CI 0-27.2)(p < 0.00001). The TRT was less in the PG-guided warfarin dosing group than the standard-of-care dosing warfarin group (17.85 vs. 33.92 days) (p = 0.002). Bleeding and thromboembolic events were similar in the two study groups. Lifetime expenditure was ₹1,26,830 in the PGT arm compared to ₹1,17,907 in the SOC arm. The QALY gain did not differ in the two groups(3.9 vs. 3.65). Compared to SOC, the incremental cost-utility ratio was ₹35,962 per QALY gain with PGT test opting. In deterministic and probabilistic sensitivity analysis, the base case results were found to be insensitive to the variation in model parameters. In the cost-effectiveness-acceptability curve analysis, a 90% probability of cost-effectiveness was reached at a willingness-to-pay(WTP) of ₹ 71,630 well below one time GDP threshold of WTP used. CONCLUSION: Clinical efficacy and the cost-effectiveness of the warfarin pharmacogenetic test suggest its routine use as a point of care investigation for patient care in LMICs.

How Do We Manage Chronic Lymphocytic Leukemia in India.

PURPOSE OF REVIEW: Chronic lymphocytic leukemia was an ignored leukemia in India until a decade back, given its low prevalence and absence of novel drugs to treat it. Healthcare in India is heterogeneous, with variations in population, health systems, and reimbursement options. We have focused on opinions from three hemato-oncologists incorporating an opinion poll from 44 hemato-oncologists across India on the common issues in CLL to give an idea of the practice pan-India. RECENT FINDINGS: More CLL patients are being diagnosed in their early stages. There is an attempt to use prognostic and predictive markers in making shared decisions for managing CLL. There is still a role for chemoimmunotherapy (CIT) in India, given limited health insurance coverage. But with the availability of inexpensive generics, the patient preference for non-CIT options like Bruton's tyrosine kinase (BTK) inhibitors is palpable. The CLL scene in India is changing rapidly. With the wide availability of economical generic small molecule inhibitors, monoclonal antibodies, and coverage by social health insurance schemes, India is poised to cater to most CLL patient needs.

GVHD relapse-free survival after peripheral blood hematopoietic cell transplantation for hematologic malignancies.

The preferred choice for hematopoietic cell transplantation (HCT) donors in India is a matched related donor (MRD) followed by a haploidentical (haplo) donor for patients with hematological malignancies. International data in the haplo-HCT setting is mainly using bone marrow as a source. Almost all HCTs in India use peripheral blood stem cells (PBSC), which increases the risk of graft-versus-host disease (GVHD). In this single-center prospective study from 2017 to 2021, we sought to compare these outcomes prospectively in adult patients with hematological malignancies. Patient, disease, donor, and HCT details were prospectively recorded. GVHD prophylaxis included cyclosporine + methotrexate in MRD-HCT and post-transplant cyclophosphamide (PTCy) based in haplo-HCT. The primary endpoint GVHD relapse-free survival (GRFS) was defined as the time post-HCT without any of the following events: grade III-IV acute GVHD, chronic GVHD requiring systemic immunosuppressive treatment, disease relapse, or death from any cause. A total of 41 MRD and 33 haplo-HCT recipients were included in the study. Both cohorts were matched for age, sex, diagnosis, disease risk index, donor age, sex and CMV mismatches, and CD34 counts. A lower proportion of MRD-HCT recipients than haplo-HCT received myeloablative conditioning (39% vs. 76%, p = 0.002). There was no difference in the cumulative incidence of grade III-IV acute GVHD (16% vs. 27%, p = 0.2) or moderate-to-severe chronic GVHD (58% vs. 71%, p = 0.5). The one-year GRFS was not significantly different (53% vs. 38%, p = 0.2), with median GRFS of 420 and 274 days. The relapse incidence (22% vs. 19%, p = 0.6) and non-relapse mortality (25% vs. 35%, p = 0.4) did not differ. There was no difference in overall survival at one year (60% vs. 52%, p = 0.3). Despite a higher proportion of myeloablative conditioning in the haplo-HCT cohort, all outcomes, including GRFS, were comparable to those of the MRD-HCT cohort. This should encourage patients without an MRD to undergo haplo-HCT.

Pregnancy and long-term outcomes of female patients with chronic myeloid leukemia on tyrosine kinase inhibitors who experienced unplanned pregnancies.

PURPOSE: Despite the general recommendation to avoid Tyrosine Kinase Inhibitors (TKIs) for Chronic Myeloid Leukemia (CML) during pregnancy, unplanned pregnancies still occur, particularly among female patients residing in low- and middle-income countries (LMICs). We aimed to investigate the outcomes of pregnancy, foetal development, and disease progression among female CML patients in chronic phase (CML-CP) undergoing TKI therapy who encountered unplanned pregnancies in a tertiary care hospital in northern India. METHODS: We conducted a retrospective analysis of all pregnancies in female CML-CP between January 2002 and December 2022 at our hospital. Patients were included if they had a confirmed diagnosis of CML-CP, were receiving TKI therapy during conception, and had available medical records. We analysed the data on pregnancy outcomes, foetal development, and disease progression through a review of medical records. RESULTS: We identified 36 pregnancies in female CML-CP patients on TKI therapy during the study period, with 33 (91.7%) being unplanned. Sixteen pregnancies (48.5%) were conceived at less than major molecular remission (MMR) status. Twelve pregnancies (36.4%) were electively terminated, 4 (12.1%) had miscarriages, and, 17 (51.5%) pregnancies resulted in childbirth. Out of the 17 childbirths, 10 were full-term deliveries, and 7 were preterm deliveries. Twin pregnancies had a high incidence (18.2%). Among the 21 pregnancies that were not electively terminated, TKI was stopped at the first pregnancy detection in 14 pregnancies, while imatinib was continued throughout 7 pregnancies. Patients who discontinued TKI had a higher but statistically non-significant incidence of adverse pregnancy outcomes compared to those who continued imatinib throughout pregnancy (64.2% vs. 28.6%, p = 0.18). Additionally, the risk of long-term disease progression among patients who discontinued TKI during pregnancy and those who continued imatinib throughout pregnancy was 21.4% and 16.7% (p = 0.9), respectively. The risk of long-term disease progression was significantly increased in those persistently at less than MMR pre- and post-gestation (p = 0.0002). CONCLUSION: Our findings suggest that continuing imatinib therapy during pregnancy, may be a reasonable option for CML patients residing in low- and middle-income countries to reduce the risk of disease progression and adverse pregnancy outcomes. Patients persistently at less than MMR levels pre- and post-gestation should be closely monitored for the risk of long-term disease progression. Further studies with larger sample sizes are needed to confirm these results.

Utility of eGVHD App for bedside GVHD assessment in a high-volume BMT center.

Assessing acute and chronic graft-versus-host disease (GVHD) is challenging because there are several classification systems. The European Society for Blood and Marrow Transplantation and the Center for International Bone Marrow Transplantation Registry task force recommends using the eGVHD application (App) to score acute GVHD according to the Mount Sinai Acute GvHD International Consortium (MAGIC) criteria and chronic GVHD according to the National Institutes of Health 2014 criteria. We prospectively used the eGVHD App at each follow-up visit in a large-volume bone-marrow transplant center in India from 2017 to 2021. We retrospectively evaluated the discrepancy in scoring GVHD severity by physicians not using the App from the same patient charts. The App user satisfaction and experience were recorded using the technology acceptance model (TAM) and the Post-Study System Usability Questionnaire (PSSUQ). In 100 consecutive allogeneic hematopoietic cell transplantation recipients, there was more discrepancy in scoring the severity of chronic GVHD (38%) than acute GVHD (9%) without using the App. The median TAM and PSSUQ scores were six (IQR:1) and two (IQR:1), respectively, indicating high perceived usefulness and user satisfaction. The eGVHD App is an excellent learning tool for hematology/BMT fellows and helps manage GVHD in high-volume BMT centers.

Randomized Controlled Trial of Isha Kriya versus Observation to Improve Quality of Life in Hematopoietic Cell Transplantation Recipients.

Hematopoietic cell transplantation (HCT) impacts recipients' quality of life (QoL). Few mindfulness-based interventions (MBI) in HCT recipients have shown feasibility, but heterogeneous practices and outcome measures have called into question the actual benefit. We hypothesized that self-guided isha kriya, a 12-minute guided meditation based on the principles of yoga focusing on breathing, awareness, and thought, as a mobile app would improve QoL in the acute HCT setting. This single-center, open-label, randomized controlled trial was conducted in 2021 to 2022. Autologous and allogeneic HCT recipients age ≥18 years were included. The study was approved by our Institutional Ethics Committee and registered at the Clinical Trial Registry of India, and all participants provided written informed consent. HCT recipients without access to smartphones or regular practitioners of yoga, meditation, or other mind-body practices were excluded. Participants were randomized to the control arm or the isha kriya arm at a 1:1 ratio stratified by type of transplantation. Patients in the isha kriya arm were instructed to perform the kriya twice daily from pre-HCT to day +30 post-HCT. The primary endpoint was QoL summary scores as assessed by the Functional Assessment of Cancer Therapy-Bone Marrow Transplantation (FACT-BMT) and the Patient-Reported Outcomes Measurement Information System Global Health (PROMIS-GH) questionnaires. The secondary endpoints were the differences in QoL domain scores. The validated questionnaires were self-administered before the intervention and at days +30 and +100 post-HCT. The analysis of endpoints was done on an intention-to-treat basis. Domain and summary scores were calculated for each instrument as recommended by the developers. A P value < .05 was considered to indicate statistical significance, and Cohen's d effect size was used to determine clinical significance. A total of 72 HCT recipients were randomized to the isha kriya and control arms. Patients in the 2 arms were matched for age, sex, diagnosis, and type of HCT. The 2 arms showed no differences in pre-HCT QoL domain, summary, and global scores. At day +30 post-HCT, there was no difference between the arms in the mean FACT-BMT total score (112.9 ± 16.8 for the isha kriya arm versus 101.2 ± 13.9 for the control arm; P = .2) or the mean global health score (global mental health, 45.1 ± 8.6 versus 42.5 ± 7.2 [P = .5]; global physical health, 44.1 ± 6.3 versus 44.1 ± 8.3 [P = .4]) in the 2 groups. Similarly, there were no differences in physical, social, emotional, and functional domain scores. However, the mean bone marrow transplantation (BMT) subscale scores, which addresses BMT-specific QoL concerns, were statistically and clinically significantly higher in the isha kriya arm (27.9 ± 5.1 versus 24.4 ± 9.2; P = .03; Cohen's d = .5; medium effect size). This effect was transient; mean day +100 scores showed no difference (28.3 ± 5.9 versus 26.2 ± 9.4; P = .3). Our data indicate that the isha kriya intervention did not improve the FACT-BMT total and global health scores in the acute HCT setting. However, practicing isha kriya for 1 month was associated with transient improvement in the FACT-BMT subscale scores on day +30 but not on day +100 post-HCT.

Post-transplant cyclophosphamide pharmacokinetics and haploidentical hematopoietic cell transplantation outcomes: an exploratory study.

Pharmacokinetics of cyclophosphamide has been explored to optimize conditioning dosing. We hypothesized that post-transplant cyclophosphamide (PTCy) metabolite carboxy-ethyl phosphoramide mustard (CEPM) pharmacokinetics might impact haploidentical transplantation (haplo-HCT) outcomes. CEPM area under the curve (AUC0-48) was determined by eleven sampling timepoints on day +3/+4 using LC-MS/MS. The median CEPM AUC0-48 in a cohort of 30 patients was 14.2 (14) mg·hr/L. The incidence of severe chronic graft-versus-host disease (GVHD) (73% vs. 11%, p = 0.02), and GVHD-/relapse-free survival (GRFS) was significantly inferior in the CEPM AUC0-48 < 14 mg·hr/L group (54 days vs. 344 days, p = 0.02). There was, however, no difference in grade III-IV acute GVHD (38% vs. 14%, p = 0.12) and overall survival (295 days vs. not reached, p = 0.2). CEPM AUC0-48, is associated with severe chronic GVHD and GRFS post-haplo-HCT in this exploratory study. There is scope for personalizing day + 4 PTCy dose based on day + 3 CEPM AUC0-8.

Short Research Communication Anti-Spike Antibody Response to COVISHIELD™ (SII-ChAdOx1 nCoV-19) Vaccine in Patients with B-Cell and Plasma Cell Malignancies and Hematopoietic Cell Transplantation Recipients.

Introduction: There is limited data on the serologic antibody responses after the ChAdOx1 vaccine in patients with hematological malignancies and hematopoietic cell transplantation recipients. There is no data on the safety and efficacy of the Indian COVISHIELD™ vaccine in this population. Methods: This study reports the anti-S antibody response to the COVISHIELD™ vaccine in a prospective cohort of patients with B-cell and plasma cell malignancies and HCT recipients at a single center. The quantitative antibodies to the SARS-CoV-2 S protein receptor-binding domain in human plasma were determined by the validated Roche Elecsys Anti-SARS-CoV-2 S kit. Results: A total of 118 patients were included over the study period from April 2021 to August 2021. The seropositivity rate at baseline and after the first and second dose of the vaccine was 39%, 66%, and 79%, respectively (p < 0.0001). The seronegative cohort had a higher median age (65 vs. 60 years, p = 0.03), were more likely to be males (81% vs. 42%, p = 0.009), had a diagnosis of B-CLPD (100% vs. 42%, p < 0.001) and were more likely to be on ibrutinib therapy (56% vs. 15%, p = 0.001). Conclusions: This study confirms the safety and efficacy of the COVISHIELD™ vaccine in patients with hematological malignancies.

Adherence to long-term follow-up preventive practices in allogeneic hematopoietic cell transplantation survivors from North India.

Introduction: There are existing international guidelines for long-term follow-up (LTFU) care of allogeneic hematopoietic cell transplantation (allo-HCT) survivors. However, implementing these guidelines represents a unique challenge in resource-challenged settings. Methods: This study aimed to evaluate adherence to recommended surveillance in allo-HCT survivors at an academic center in North India and study the incidence of late effects. This single-center, retrospective study analyzed records of allo-HCT recipients from 2016 to 2020. Survivors were screened in our LTFU clinic at day +100 and +365 using cardiometabolic parameters (screening for hypertension, dyslipidemia, hyperglycemia, 24-hour urine protein, thyroid function), pulmonary function test (PFT), bone mineral density (BMD), and initiation of revaccination. Results: A total of 40/80 (50%) allo-HCT survivors were alive at a median of 888 days (IQR 515-1,306). The adherence to home-based screening parameters such as blood pressure and blood glucose was highest (>75%), followed by lab-based parameters (45-70%), and lowest for specialized tests such as PFT (<50%) at both day +100 and +365 time points. Adherence to the initiation of revaccination was only 67%. At least one cardiometabolic parameter was out of range in 55% and 63% of survivors at day +100 and +365, respectively. Conclusion: The adherence to recommended surveillance measures for allo-HCT survivors in an academic LTFU clinic at one year was only 75% overall. Cardiometabolic abnormalities were noted in more than half of the survivors. This study emphasizes the need for a structured LTFU clinic in all centers performing HCT.

Impact of broad-spectrum antibiotic exposures and multidrug-resistant gram-negative bacteremia on hematopoietic cell transplantation outcomes.

INTRODUCTION: There is a close association between the use of broad-spectrum antibiotics, gut microbiome alteration, multidrug resistant (MDR) gram-negative bacilli (GNB) bacteremia, graft versus host disease (GVHD), and mortality post-allogeneic hematopoietic cell transplantation (allo-HCT). This study reports the impact of the high use of carbapenems and colistin and MDR bacteremia pre- and post-HCT on HCT outcomes. METHODS: This was a single-center, partial retrospective, and prospective study from 2016 to 2020. Both pre- and post-HCT antibiotic exposures and blood culture/sensitivity were recorded. MDR GNB was defined as either non-susceptibility to third-generation cephalosporin or carbapenems. In the absence of positive cultures, the treating physician escalated antibiotics from third-generation cephalosporins to carbapenem and/or colistin as per clinical discretion. De-escalation policy was not strictly enforced. RESULTS: MDR GNB bacteremia was seen in 29 of 76 (38%) of patients peri-HCT. The utilization rates for carbapenems and colistin was significantly higher in the cohort with MDR GNB bacteremia pre-HCT (70% vs. 32%, p = 0.002 and 31% vs. 6.4%, p = 0.007, respectively) and post-HCT (100% vs. 74.5%, p = 0.002, and 55.2% vs. 8.5%, p < 0.0001, respectively). The cohort with MDR GNB bacteremia had significantly more severe acute GVHD at day+100 (45% vs. 17.5%, p = 0.009). The median survival was 204 days compared to not reached in the cohort without any MDR GNB bacteremia (p = 0.005). CONCLUSION: This study shows pre- and post-HCT MDR GNB bacteremia is associated with an increased risk of severe acute GVHD and mortality. Patients with MDR GNB bacteremia had higher exposure to pre- and post-HCT carbapenems and colistin.

Health-related quality of life in transplant eligible multiple myeloma patients with or without early ASCT in the real-world setting.

There is no comparative health-related quality of life (HR-QoL) data of transplant eligible (TE) multiple myeloma (MM) patients undergoing early autologous stem cell transplantation (ASCT) and those without in the era of novel drugs. This study prospectively evaluated the serial HR-QoL in TE-MM using the EORTC QLQ-C30 and MY20 questionnaires. Barring the transient worsening in QoL one-month after ASCT, there was a comparable improvement in most QoL domains in both early-ASCT and no-early ASCT cohorts. Post-early-ASCT patients had higher global health scores (71.9 vs. 60.8, p < .05) than no-early ASCT at 12-months. Patients belonging to lower socioeconomic status (SES) were more likely not to undergo ASCT than middle-high SES patients (38.6% vs. 74.5%, p < .05). While age, gender had no impact on QoL, performance status, staging, and induction therapy impacted QoL. This study shows that early ASCT maintains QoL and should be encouraged in all TE-MM patients.

Role of pre-transplant chest high-resolution computed tomography and serum galactomannan index in predicting post-transplant invasive pulmonary aspergillosis in allogeneic hematopoietic cell transplant recipients.

INTRODUCTION: The role of pre-HCT chest high-resolution computed tomography (HRCT) and serum galactomannan index (GMI) in predicting the post-allogeneic hematopoietic cell transplant (HCT) invasive pulmonary aspergillosis (IPA) is debatable. METHODS: This was a single-center, prospective study from 2014 to 2019. The primary objective was to study if pre-HCT chest HRCT and serum GMI predicted IPA post-HCT. The secondary objective was day +100 mortality. All consecutive, consenting patients of ≥12 years of age undergoing allo-HCT were included and had pre-HCT chest HRCT and serum GMI. All patients received mold active antifungal prophylaxis. The EORTC/MSG criteria were used for the diagnosis of IPA. RESULTS: A total of 82 patients with median age 27 years (12-59 years) were included. The underlying diagnoses included hematological malignancies (79%) and aplastic anemia (21%). Fifteen percent of patients was treated for prior history of probable IPA (>6 weeks before HCT). Pre-HCT chest HRCT satisfied EORTC clinical criteria in 24% patients. Serum GMI ≥0.5 was seen in 27% of patients. Post-HCT probable IPA was seen in 24% of patients. There were more patients with pre-HCT chest HRCT findings satisfying EORTC clinical criteria (45% vs. 18%, P = .014) and GMI ≥0.5 (45% vs. 21%, P = .03) in the group with post-HCT IPA compared to those without IPA. There was higher day+100 mortality in patients with post-HCT IPA (55% vs. 18%, P = .001). CONCLUSIONS: The presence of EORTC clinical criteria on pre-HCT chest HRCT, serum GMI ≥0.5, and prior history of IPA predicted post-HCT IPA.

Efficacy, safety, and quality of life of generic and innovator ibrutinib in Indian CLL patients.

To report the efficacy, safety, and quality of life (QoL) on generic and innovator ibrutinib in Indian CLL patients. This was a single centre, prospective study of treatment-naive (TN), and relapsed/refractory (R/R) CLL patients receiving ibrutinib in India. The choice of innovator or generic ibrutinib was as per patient discretion. Response and adverse events were recorded as per the 2018 iwCLL guidelines and CTCAEv4.0. QoL was assessed using the EORTC QLQ-C30 and CLL17 questionnaires. A total of 32 CLL patients (TN, n = 7 and R/R, n = 25) received ibrutinib from 2016-2019. The median age was 60 years (37-84). All TN patients attained partial response without any grade 3/4 adverse events (AE). Ibrutinib was less tolerated in the R/R setting, with 52% patients developing grade 3/4 AE and required dose reduction. Eleven patients (44%) died during follow-up. Grade 3-5 infections were seen in 44% of R/R CLL patients. Generic ibrutinib (n = 8) was comparable to innovator ibrutinib (n = 17) in terms of efficacy, safety, and QoL. Ibrutinib is less well tolerated in Indian R/R CLL patients. Infections are a common cause of morbidity and mortality. This study affirms the safety and efficacy of generic ibrutinib.

Randomized controlled trial of individualized, low dose, fixed duration lenalidomide maintenance versus observation after frontline chemo-immunotherapy in CLL.

Lenalidomide maintenance after frontline chemo-immunotherapy (CIT) in chronic lymphocytic leukemia (CLL) has not been standard due to the availability of novel therapies, though these remain out of reach for most in low-middle income countries. This single-center, open-label study randomized CLL patients (non-deletion 17p) after frontline therapy to lenalidomide maintenance (dose-escalated 2.5-10mg, 20/28 days per cycle for six months) or observation (2:1 allocation). Forty patients were included over 2018-2020. At a median follow-up of 22 months, median progression-free survival (PFS) with lenalidomide was not significantly different than observation (26 vs. 18 months, p = 0.4). Patients with minimal residual disease >10-2 had a trend toward better PFS with lenalidomide (19 vs. 7 months, p = 0.07). Grade 3 neutropenia was seen in 16.7% of patients on lenalidomide. Quality of life was comparable between the two arms. Low dose, fixed duration lenalidomide maintenance is not an effective strategy after frontline CIT in CLL.

Early bone loss in Indian patients undergoing allogeneic hematopoietic cell transplantation.

Background: There is a lack of prospective studies to address the issue of timing of bone mineral density (BMD) measurement and anti-resorptive therapy before and after allogeneic hematopoietic cell transplantation (allo-HCT), specifically in the younger population (age < 40 years). This study evaluated the incidence and risk factors of poor BMD in young Indian patients undergoing allogeneic hematopoietic cell transplant and the effect of anti-resorptive therapy in allogeneic transplant recipients who are at high risk for severe bone loss. Methods: This was a single-center, prospective study conducted from 2016 to 2019. All patients aged ≥ 12 years undergoing allo-HCT were included in the study. Data regarding the risk factors for osteoporosis, underlying diagnoses, and HCT characteristics were recorded. BMD was measured by dual-energy X-ray absorptiometry (DXA) (HOLOGIC Discovery A) at the lumbar spine (LS), femoral neck (FN), and total hip (TH) at pre-HCT, day+100, and day+365 post-HCT. Patients with Z-score ≤ -2 at day+100 were given one dose (4 mg) of intravenous zoledronate. Patients with moderate to severe chronic graft-versus-host disease (GVHD) also received a dose of zoledronate if they had not received it earlier. Results: The median age of our cohort was 24 years (IQR 18.5 - 39.5). Day+100 DXA was available for 25 (54.3%) patients, a paired day+100, and day+365 DXA was available for 15 patients. For pre-HCT, a Z-score ≤ -2 was seen in 30% of patients. For day+100 post-HCT, a Z-score ≤ -2 was seen in 44% of patients. Low body mass index was associated with a Z-score ≤ -2 (median 18 vs. 23 kg/m2, P = 0.04). Despite a single dose of zoledronate in this cohort, the median Δ BMD (day+365 - day+100) loss at FN and LS was -0.8% to -3.7%, respectively. Seven (64%) of these patients also had moderate-severe chronic GVHD. Conclusions: BMD below the expected range for age (Z-score ≤ -2) was present in one-third of young Indian patients undergoing allo-HCT in this single center study. Without intervention, up to half of the patients had a Z-score ≤ -2 at day+100 post-HCT. BMD loss at day+100 persisted at day+365 despite anti-resorptive therapy.

Long-term outcomes of innovator versus generic melphalan formulation in autologous hematopoietic cell transplantation for multiple myeloma.

BACKGROUND: Most data on autologous hematopoietic cell transplantation (auto-HCT) in myeloma are based on the use of innovator formulation of melphalan. Comparative bioequivalence and efficacy studies of generic melphalan are lacking. METHODS: In this retrospective study, we report long-term outcomes of auto-HCT in myeloma using innovator (Alkeran, Aspen Pharma; n = 41) and generic melphalan (Alkacel, Celon Labs, India; n = 55) formulations. All consecutive patients at a single center from the period 2011-2018 were included. RESULTS: The median follow-up in the innovator and generic groups was 61.7 and 32.5 months, respectively. Both groups were matched for age, sex, stage, and myeloma response. There were significantly more patients in the innovator melphalan group who were administered melphalan at a reduced dose at physician discretion (26.8% vs. 3.6%, p = .001). There were significantly more patients with grade 3 or higher mucositis (68.3% vs. 38.1%, p < .0001) and grade 3 or higher diarrhea (85.4% vs. 50.1%, p < .0001) in the innovator group. The median duration of hospital stay was significantly longer in the innovator group (19 days vs. 15.5 days, p < .0001). There were significantly more patients in the generic group who received standard maintenance (94.5% vs. 34.1%, p < .0001). Despite the differences in the melphalan dose and post-transplant strategies, the 4-year progression-free survival and overall survival were not significantly different in the two groups (58% vs. 63%, p = .7, 71% vs. 72%, p = .4, respectively). CONCLUSION: Long-term efficacy comparison is helpful in the absence of postmarketing bioequivalence studies of generic melphalan.

A systematic review of economic evaluations of treatment regimens in multiple myeloma.

BACKGROUND: The expansion of advanced expensive therapeutic innovations for Multiple Myeloma (MM) led to increased disclosure of economic evaluations. The present analysis systematically reviewed and appraised the reporting quality of economic evaluations in MM. METHODOLOGY: A comprehensive literature search in Ovid, MEDLINE(R), PubMed, and Cochrane libraries was conducted for studies published in the past decade. Two independent authors performed study selection and data extraction in a standardized form. Study methodological quality assessment was performed using 10-item Drummond's tool. RESULTS: Of potentially eligible 1150 retrieved studies, 17 met eligibility criteria. Six evaluations (35%) were in newly diagnosed MM and 11 (65%) in relapse refractory (RR) MM. Nine studies (53%) embraced the payer's perspective, five (29%) adopted health care system, one (6%) societal and two did not report. Six (35%) employed partitioned survival model, 4(24%) discrete event simulation, 4(24%) Markov model and 2(12%) used decision tree model. The methodological quality has improved significantly; 16 (94%) studies comprehended a well-defined question by affirming the analysis perspective and examined both costs and outcomes while 13 (71%) provided a comprehensive description of competing alternatives. CONCLUSION: The addition of novel drugs to the treatment armamentarium of MM is considerably cost-effective. The evaluations became more frequent, methodological quality has improved in the last decade.

Genomic alterations in chronic lymphocytic leukemia and their correlation with clinico-hematological parameters and disease progression.

BACKGROUND: Chronic lymphocytic leukemia (CLL) is a heterogeneous disease, which is attributed to differences in the genetic characteristics of the leukemic clone. We studied the genomic profile of 52 treatment-naïve CLL patients. METHODS: Genetic analysis was performed by multiplex ligation-dependent probe amplification (MLPA) using the SALSA P038 Probemix (MRC Holland, Amsterdam), which contains probes for 2p (MYCN,ALK,REL), 6q, 8p (TNFRSF10A/B), 8q (EIF3H,MYC), 9p21 (CDKN2A/B), 10q (PTEN), 11q (ATM, RDX, PPP2R1B, CADM1), chromosome 12, 13q14 (RB1, DLEU1/2/7, KCNRG, MIR15A), 14q, 17p (TP53) and chromosome 19, and for NOTCH1 7541-7542delCT, SF3B1 K700E, and MYD88 L265P mutations. RESULTS: The median age was 65 years (male:female=2:1). The median hemoglobin, total leukocyte, and platelet counts were 12.4 g/dL, 57.7×109/L, and 176.5×109/L, respectively. At least one genetic abnormality was observed in 34 (65%) patients. The most common abnormality was del(13q14) (deleted DLEU2 and DLEU1/RB1 genes), which was observed in 22 (42%) cases, followed by trisomy 12 [7 (13%) cases]. Del(11q) (deleted ATM, RDX11/PPP2R1B-4) and del(17p) (deleted TP53) were present in 5 (10%) and 2 (4%) cases, respectively. 19p13.2 (CDKN2D-2) amplification and NOTCH1 mutation were found in one case each. CONCLUSION: Genetic abnormalities are commonly (65%) observed in CLL patients. Del(13q), which is associated with DLEU2 and DLEU1/RB1 gene deletion, was the most common. Compared with other abnormalities, del(11q) and del(17p) patients presented with cytopenia and higher Binet stage, while those with del(13q14) had a longer time to first treatment.

Quality of life in patients of chronic lymphocytic leukemia using the EORTC QLQ-C30 and QLQ-CLL17 questionnaire.

INTRODUCTION: The quality of life (QoL) analysis is likely to differ by region, ethnicity, and questionnaires in comparison with age-matched healthy controls. METHODS: The EORTC QLQ-C30 and QLQ-CLL17 questionnaire validated in regional languages were administered to 127 consecutive CLL and 100 age-matched, healthy controls at a single center from 2018 to 2019. RESULTS: All groups of CLL patients either on wait and watch (W&W) or on treatment had significantly impaired QoL in all functional domains including global health compared to controls (P < .0001). CLL patients had significantly higher symptom scores than controls in most domains (P < .0001, 0.03 for diarrhea). There was no difference in the QoL by age or gender. Lower socioeconomic status patients had higher financial difficulty (P = .02). Patients on CIT had the worst global health (OR 12.21 compared to patients on W&W) (P = .03). Patients on ibrutinib had less worries/fears about health and functioning than patients who were on CIT (P = .04). CONCLUSIONS: Quality of life is severely affected in CLL patients on W&W. Global health status and worries about future health and functioning were major concerns. Socioeconomic status but not age or gender impacted QoL. Patients on ibrutinib had better QoL than on CIT.
