Inflammatory bowel disease (IBD) is a constellation of devastating chronic inflammatory changes in the bowel, either involving the large or small bowel or part of both. As it is widely diagnosed in the fertile age group, this disorder can present itself, very commonly, during pregnancy and thus a better understanding of the disease can be an important factor to influence the maternal and fetal well-being. Medications are what is considered the first line in the management of this disease to control the symptoms or keep the disease in remission. In addition to this, the drugs used to keep the disease in remission can also cause significant adverse effects on the patient and the new nurturing life preparing itself for the outside world. What the fetus gets from the mother will stay for life with the child. We conducted an electronic literature review search which highlights the significance and impact of sustained remission of IBD and the cautious use of various drugs during pregnancy for that purpose. In addition to the influences already mentioned, It is evident that nutritional deficiencies can also prevail with the advancing disease, something to manage as a side note as well. These deficiencies can have a definite effect on the fetus and may cause developmental malformations. In order to avoid this process, a systemic and joint approach should be curtailed. This can reduce the adverse outcomes associated with this ailment during pregnancy.
Introduction: Selinexor, an exportin 1(XPO1) inhibitor has demonstrated anti-leukemia activity as a single agent, as well as in combination regimens for the treatment of acute myeloid leukemia (AML). This systematic review aims to explore the efficacy and safety of selinexor based regimens for the treatment of AML. Methods: A systematic literature search was conducted using PubMed, Embase, Cochrane library, ClinicalTrials.gov, ASCO, and ASH meeting websites. The initial databases yielded 698 articles (last updated search until July 20, 2020). After excluding review articles, duplicates, and non-relevant articles, we included data from eight clinical trials (Table 1 and Table 2). Results: Among a total of 286 patients, 259 were evaluated. Selinexor was given as monotherapy to 81 patients and as combination regimens to 178 patients. The total newly diagnosed (ND) AML patients were 48 and relapsed refractory (RR) AML patients were 238. Garzon et al. did a phase I dose-escalation trial (n=81) with selinexor as a single agent in ND-AML and RR-AML patients with a median of three prior lines of therapy. The overall response rate (ORR) was 14%. The median overall survival (OS) was 2.7 months and median progression-free survival (PFS) was 1.7 months. 15% of the patients discontinued the treatment temporarily due to adverse events (AEs). Bhatnagar et al. (n=25) studied selinexor with decitabine, in phase I clinical trial, in ND and RR-AML patients. The ORR was 40% with higher ORR in ND-AML (80%) compared to RR-AML (30%). At a median follow-up of 21.8 months, the median PFS was 5.9 months (95% CI: 2.4-8.7) and median OS was also 5.9 months (95% CI: 3.9-10.4). The PFS was longer for patients who responded to therapy (11.8 months) as compared to those who did not respond to therapy (4.4 months). In phase I/II trial by Daver et al. (n=14) with selinexor and sorafenib in RR-AML patients, the composite complete remission including CR, CR with incomplete blood count recovery (Cri), and CR with incomplete platelet recovery (CRp) was 35.7%. The event-free survival was 1.8 months (0.4-5.0) in FLT3-ITD Inhibitor failure cohort vs 2.1 months (0.7-2.1) in FLT3-ITD inhibitor naive cohort. A single-arm phase I study with selinexor, cytarabine, and daunorubicin was performed testing ND-AML patients by Sweet et al., (n=19). It showed an ORR of 53% and a median OS of 10.3 months (95% CI: 3.74-NR). The early death rate (death ≤ 60 days) was 4.8%. The phase I dose-escalation trial by Weng et al. (n=28) in ND and RR-AML patients with selinexor+cytarabine+mitoxantrone had a better response rate. The ORR was 64% with a higher ORR in ND-AML (87%) compared to RR-AML (38%). The phase I trial by Alexander et al. (n=18) with selinexor+ cytarabine+ fludarabine on RR-AML patients achieved an ORR of 60 % and CR of 33.3%. Fielder et al. (n=38) did a phase II clinical trial on RR-AML patients with selinexor+ cytarabine + idarubicin with 40 mg/m2 selinexor in one cohort (C1) and flat 60 mg dose of selinexor in the second cohort (C2). In C1 37% of patients and C2 40% of patients had previous stem cell transplantation (SCT). The ORR was almost the same in both cohorts, with 55 % in C1 vs 54.5% in C2. The phase I/II trial on RR-AML patients by Abboud et al. (n=40) with selinexor+ cladribine+cytarabine+filgrastim had a total of CR and CRi in 45% of patients with a median overall survival of 7.8 months (95%CI: 5.7-14.1) and median event-free survival of 6.1 months (95% CI: 4.5 - 7.8 months). The main hematological adverse events were pancytopenia and non-hematological adverse events were hypophosphatemia, hyponatremia, gastrointestinal disturbances, and fatigue (Table 2). Conclusion: Selinexor in combination regimens showed superior response rates compared to selinexor alone for the treatment of AML patients. The response rates were better in selinexor based three and four-drug regimens.

Introduction: In Multiple Myeloma (MM), nuclear exporter exportin-1 (XPO1) is a target for selinexor. Selinexor has a promising efficacy and a favorable safety profile in relapsed refractory MM. This systemic review aims to explore the efficacy and safety of selinexor based regimens for the treatment of relapsed refractory multiple myeloma (RRMM). Materials and Methods: We conducted a literature search using four databases (PubMed, Embase, Cochrane library, and ClinicalTrials.gov). Our search strategy included MeSH (Medical Subject Headings) terms and keywords for multiple myeloma and Selinexor including trade and generic names from the date of inception to April 13, 2020. Initial databases yielded 115 articles. After excluding review articles, duplicates, and non-relevant articles, we included six clinical trials reporting the efficacy of Selinexor in RRMM. Results: Among a total of 310 enrolled patients, 288 patients were evaluated. Selinexor was given in combination with dexamethasone to 207 and as three drug regimens to 103 RRMM patients. Chen et al. studied the efficacy of selinexor plus dexamethasone (d) in RRMM pts (n=70) in phase I trial achieved an overall response rate (ORR) of 10%, stable disease (SD) of 31% and progressive disease (PD) of 27%. Similarly, Chari et al. studied selinexor + dexamethasone in RRMM pts (n=122) in phase IIb trial, and observed ORR of 28%. The median overall survival (OS) was 8.6 months (95% CI, 6.2 to 11.3) and a median progression-free survival (PFS) was 3.7 months (95% CI, 3.0 to 5.3) with SD of 39% and PD of 21%. Chen et al. studied selinexor in combination with pomalidomide (P) + d in RRMM patients (n=46), achieved an ORR of 50% and the median PFS of 10.4 months. The disease was stable in 24% of patients with a low rate of progression i.e. 2%. In a phase Ib/II trial using selinexor + carfilzomib + d by Gasparetto et al. (n=12), the ORR was 75%, with SD of 16.67%. Selinexor in combination with doxorubicin and d was studied in phase I/II trial by Baz et al. (n=27) with ORR of 15% and SD in 30% of patients. Brojil et al. reported the role of selinexor + bortezomib + d in RRMM (n=11) in phase II trial with partial response (PR) of 80%. The median PFS was 17 months and one-year overall survival (OS) was 100%. The majority of hematological adverse effects were pancytopenia. The main non-hematological adverse effects were pneumonia, and peripheral sensory neuropathy. Conclusion:Selinexor showed promising outcomes in terms of ORR for the treatment of RRMM. The responses in selinexor based three-drug regimens were observed higher as compared to two-drug regimens, providing a benchmark for future studies.

Background: Multiple myeloma (MM) is a plasma cell disorder and demonstrates overexpression of B cell maturation antigen (BCMA). Our objective is to evaluate the safety and efficacy of chimeric antigen receptor T cells (CAR-T) against BCMA in patients with relapsed/refractory multiple myeloma (RRMM). Methods: We conducted a systematic literature search using PubMed, Cochrane, Clinicaltrials.gov, and Embase databases. We also searched for data from society meetings. A total of 935 articles were identified, and 610 were screened for relevance. Results: Data from thirty-one original studies with a total of 871 patients (pts) were included based on defined eligibility criteria, see Table 1. Hu et al. reported an overall response rate (ORR) of 100% in 33 pts treated with BCMA CAR-T cells including 21 complete response (CR), 7 very good partial response (VGPR), 4 partial response (PR). Moreover, 32 pts achieved minimal residual disease (MRD) negative status. Chen et al. reported ORR of 88%, 14% CR, 6% VGPR, and 82% MRD negative status with BCMA CAR-T therapy in 17 RRMM pts. In another clinical trial by Han et al. BCMA CAR-T therapy demonstrated an ORR of 100% among 7 evaluable pts with 43% pts having ≥ CR and 14% VGPR. An ORR of 100% with 64% stringent CR (sCR) and 36% VGPR was reported with novel anti-BCMA CART cells (CT103A). Similarly, Li et al. reported ORR of 87.5%, sCR of 50%, VGPR 12.5%, and PR 25% in 16 pts. BCMA targeting agent, JNJ-4528, showed ORR of 91%, including 4sCR, 2CR, 10MRD, and 7VGPR. CAR-T- bb2121 demonstrated ORR of 85%, sCR 36%, CR 9%, VGPR 57%, and MRD negativity of 100% (among 16 responsive pts). GSK2857916, a BCMA targeting CAR-T cells yielded ORR of 60% in both clinical trials. Three studies utilizing bispecific CART cells targeting both BCMA & CD38 (LCARB38M) reported by Zhao et al., Wang et al., and Fan et al. showed ORR of 88%, 88%, & 100% respectively. Topp et al. reported ORR of 31% along with 5 ≥CR and 5 MRD negative status in 42 pts treated with Bi T-cells Engager BiTE® Ab BCMA targeting antigen (AMG420). One clinical trial presented AUTO2 CART cells therapy against BCMA with an ORR of 43%, VGPR of 14%, and PR of 28%. CT053CAR-BCMA showed 14sCR and 5CR with a collective ORR of 87.5% and MRD negative status of 85% in 24 and 20 evaluable pts, respectively. Likewise, Mikkilineni et al. reported an ORR of 83%, sCR of 16.7%, and VGPR & PR of 25% and 41% in 12 pts treated with FHVH-BCMA T cells. Similar results are also reported in other clinical trials of BCMA targeting CART therapy (Table 1). The most common adverse effects exhibited were grade 1-3 hematologic (cytopenia) and cytokine release syndrome (CRS) (mostly reversible with tocilizumab). Conclusion: Initial data from ongoing clinical trials using BCMA targeting CAR-T therapy have yielded promising results both in terms of improved outcome and tolerable toxicity profiles. Although two phase 3 trails are ongoing, additional data is warranted to further ensure the safety and efficacy of anti-BCMA CAR-T cells therapy in pts with RRMM for future use.
