Abstract In iron deficiency anaemia patients, intravenous administration of either ferric carboxymaltose (FCM) or iron isomaltoside (IM) both allow high dosage iron substitution within a single outpatient visit. In contrast, other iron compounds require repetitive, low dosage infusions. Recently, FCM was reported to frequently induce acute, reversible hypophosphatemia. It remains enigmatic whether these hypophosphataemic effects of FCM are substance-specific, or whether they generally occur after high dosage iron substitution. A direct comparison of phosphorus regulation after high dosage iron substitution with either FCM or IM is clinically important, as hypophosphatemia after FCM has anecdotally been associated with osteomalacia and bone fractures. In the HOMe AFers 1 (HOMburg evaluations on application of Ferrum study 1) trial, we recruited normophosphatemic women with gynaecological bleeding and subsequent iron deficiency anaemia, in whom we assessed the longitudinal biochemical response over 28 days to a single intravenous injection of equivalent doses of randomly-assigned FCM and IM (1000 mg). The primary study hypothesis was that the incidence of hypophosphatemia - defined as plasma phosphorus < 2.0 mg/dl at least out of three post-infusion study time points (day 1, day 8, and week 5) - differs between FCM and IM. HOMe AFers 1 initially planned to recruit 60 women. An interim analysis was pre-specified and scheduled in July 2018, with the option to stop further patient recruitment if the incidence of hypophosphatemia differs significantly at this interim analysis. At the time point of the interim analysis, 26 patients have been recruited. One patient withdrew her acceptance to participate after day 1, leaving 25 patients for our per protocol interim analysis. Baseline plasma phosphorus did not differ significantly between FMC (3.3 ± 0.4 mg/dl) and IM (3.6 ± 0.6 mg/dl; p = 0.135). Analysis on the primary endpoint demonstrated that significantly more women developed hypophosphatemia < 2.0 mg/dl after FMC infusion (9 out of 12 patients) than after IM infusion (1 out of 13 patient) (p=0.001). Further, the minimum plasma phosphorus during any of the three post-infusion study time points was lower after FMC (1.8 ± 0.3 mg/dl) than after IM (2.7 ± 0.6 mg/dl; p < 0.001). As expected, ferritin and haemoglobin increased in both study groups after iron infusion. No severe adverse events occurred in either group. In conclusion, while both FCM and IM provide efficient iron substitution in iron deficiency anaemia, FCM induced a substantially higher incidence of hypophosphatemia.

BACKGROUND Anaemia is one of the major public health problems in developing nations. Iron deficiency anaemia (IDA) is the commonest type of anaemia in pregnancy. Parenteral iron therapy is a recommended modality of treatment of IDA. Inj. Ferric Carboxymaltose (FCM) is a dextran free preparation which is safe, easy to deliver and better tolerated. A maximum of 1000 mg can be infused at a time. The present study was intended to assess the efficacy and safety of Inj. FCM in the treatment of iron deficiency anaemia in the second and third trimester. METHODS This prospective study was conducted at a tertiary care centre at Pune. Pregnant women with iron deficiency anaemia of moderate and severe grade were infused 1000 mg of Inj. FCM by longer infusion protocol. A total of 165 pregnant women were included in the study. The efficacy of Inj. FCM was monitored by the rise in the haemoglobin level at 03-, 06- and 08-weeks post infusion of FCM injection and serum Ferritin levels. The safety was assessed by analysing the adverse reactions. RESULTS No serious adverse reaction was recorded in any of the patients. The rise in haemoglobin (Hb) in second and third trimester of moderate and severe grade of anaemia was significant (P < 0.001). The target level of 10 g / dl was achieved in every patient. Only 03 patients received blood transfusion and that was for obstetric indications. No blood transfusion was because of anaemia per se. The rise in serum ferritin level was also statistically significant (P < 0.001). CONCLUSIONS Inj. FCM is an excellent modality to treat iron deficiency anaemia in pregnancy. It is safe and the rise of haemoglobin with correction of anaemia is satisfactory in a short span of time. In our country where only a handful of patients had regular antenatal check-up and non-compliancy and refractory anaemia is rampant, Inj. FCM is a big boon. KEYWORDS Iron Deficiency Anaemia, Inj.

Abstract The Multiple Myeloma Research Foundation (MMRF) CoMMpass trial (NCT145429) is a longitudinal study of 1000 patients with newly-diagnosed multiple myeloma from clinical sites in the United States, Canada, Spain, and Italy. Each patient receives a treatment regimen containing a proteasome inhibitor, immunumodulatory agent, or both. Clinical parameters are collected at study enrollment and every three months through the five-year observation period. To identify molecular determinants of clinical outcome each baseline and progression tumor specimen is characterized using Whole Genome Sequencing, Exome Sequencing, and RNA sequencing. This will be the first public presentation of the interim analysis seven cohort with 760 enrolled patients of whom 565 are molecularly characterized. This cohort of patients includes 14 patients with baseline and secondary samples along with 7 patients with characterized tumor samples from the bone marrow and peripheral blood. Although the median follow-up time for the cohort is only 260 days the patients on proteasome and IMiD based combinations are currently showing a PFS and OS benefit compared to those receiving combinations with each agent alone. From the raw mutational analysis we identified 24 significant genes that are recurrently mutated and the mutated allele is detectably expressed in all but one, DNAH5. Suggesting these mutations are likely contributing to myelomagenesis through an unconventional mechanism. Interestingly, DIS3 mutations are independent of KRAS, NRAS, and BRAF indicating a potential mechanistic link while PRKD2 mutations are associated with t(4;14). To identify events driving the initiation of myeloma we performed a detailed clonality analysis using a bayesian clustering method that corrects for copy number abnormalities and tumor purity to assign mutations into distinct clonal branches versus the initiating trunk mutations. On average 63.8% of mutations are trunk mutations and in 86.7% of patients at least one trunk mutation is associated with somatic hypermutation of an immunoglobulin gene as expected in a late stage B-cell malignancy. This identified many expressed trunk mutations that did not come out in the classic significance analysis like ATM, EGR1, and CCND1. To identify molecular subtypes we performed unsupervised clustering using a consensus clustering approach on independent discovery and validation cohorts, which identified 12 distinct subtypes, using a combination of silhouette score and cumulative distribution of consensus scores. This analysis identified two distinct groups associated with t(4;14) with mutations in FGFR3 and DIS3 being exclusive to one subgroup. In addition, this analysis separates patients with cyclin D translocations into three different groups, with one group having the second lowest PFS proportion. Three patients without CCND1 or CCND3 translocations were found to have IgH translocations targeting CCND2. The MAF subgroup was associated with the lowest OS and PFS proportion, and the three MAF/MAFB translocation negative patients in the subgroup all had MAFA translocations. The remaining 6 subgroups are associated with hyperdiploid copy number profiles and harbor the majority of the IgH-MYC translocation events. Two of the hyperdiploid groups are associated with a low level of NFKB activation compared to the remaining four, one of these is defined by the highest proliferation index but paradoxically the other has the second worst OS proportion. Another group is enriched with FAM46C and NRAS mutations. The genomic profiles of the paired tumors isolated from the peripheral blood and bone marrow are highly similar indicating these are not genetically distinct tumor compartments, at least in this subset of seven patients. Applying our bayesian clustering method to the serial samples resolved additional clonal clusters as mutations with similar cancer cell fractions at diagnosis clearly diverged at later timepoints. These analyses have identified tumor initiating mutations and new subtypes of myeloma, which are associated with distinct molecular events and clinical outcomes.
