Severe postural hypotension and sinus bradycardia with thalidomide in patients with erythema nodosum leprosum.

Two men in their 60s and 40s were diagnosed with erythema nodosum leprosum based on the development of recurrent painful ulcers and nodules, respectively, for the previous 6 months. Thalidomide 100 mg four times a day, along with MB-MDT, was started in both patients. Both patients experienced severe dizziness on rising from a seated posture soon after initiation of thalidomide and a decrease in blood pressure and heart rate. Cardiovascular/neurology examination and routine blood investigations were normal. An autonomic nervous system assessment indicated bradycardia, postural hypotension and decreased cardiac autonomic function. The dosage of thalidomide was then gradually reduced over 4-5 days to 100 mg/day following a suspicion that thalidomide was the cause of postural hypotension. The dizziness subsided, and blood pressure and heart rate returned to normal.We concluded that thalidomide was the culprit behind bradycardia and dose- dependent postural hypotension.

Pomalidomide for Epistaxis in Hereditary Hemorrhagic Telangiectasia.

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is characterized by extensive telangiectasias and arteriovenous malformations. The primary clinical manifestation is epistaxis that results in iron-deficiency anemia and reduced health-related quality of life. METHODS: We conducted a randomized, placebo-controlled trial to evaluate the safety and efficacy of pomalidomide for the treatment of HHT. We randomly assigned patients, in a 2:1 ratio, to receive pomalidomide at a dose of 4 mg daily or matching placebo for 24 weeks. The primary outcome was the change from baseline through week 24 in the Epistaxis Severity Score (a validated bleeding score in HHT; range, 0 to 10, with higher scores indicating worse bleeding). A reduction of 0.71 points or more is considered clinically significant. A key secondary outcome was the HHT-specific quality-of-life score (range, 0 to 16, with higher scores indicating more limitations). RESULTS: The trial was closed to enrollment in June 2023 after a planned interim analysis met a prespecified threshold for efficacy. A total of 144 patients underwent randomization; 95 patients were assigned to receive pomalidomide and 49 to receive placebo. The baseline mean (±SD) Epistaxis Severity Score was 5.0±1.5, a finding consistent with moderate-to-severe epistaxis. At 24 weeks, the mean difference between the pomalidomide group and the placebo group in the change from baseline in the Epistaxis Severity Score was -0.94 points (95% confidence interval [CI], -1.57 to -0.31; P = 0.004). The mean difference in the changes in the HHT-specific quality-of-life score between the groups was -1.4 points (95% CI, -2.6 to -0.3). Adverse events that were more common in the pomalidomide group than in the placebo group included neutropenia, constipation, and rash. CONCLUSIONS: Among patients with HHT, pomalidomide treatment resulted in a significant, clinically relevant reduction in epistaxis severity. No unexpected safety signals were identified.

Cost-per-responder analysis of patients with lenalidomide-refractory multiple myeloma receiving ciltacabtagene autoleucel in CARTITUDE-4.

Introduction: Ciltacabtagene autoleucel (cilta-cel) is a chimeric antigen receptor T-cell therapy approved for patients with relapsed/refractory multiple myeloma (RRMM). In the phase 3 trial, CARTITUDE-4 (NCT04181827), cilta-cel demonstrated improved efficacy vs. standard of care (SOC; daratumumab plus pomalidomide and dexamethasone [DPd] or pomalidomide plus bortezomib and dexamethasone [PVd]) with a ≥ complete response (≥CR) rate of 73.1% vs. 21.8%. Methods: A cost-per-responder model was developed to assess the value of cilta-cel and SOC (87% DPd and 13% PVd) based on the CARTITUDE-4 trial data from a US mixed payer perspective (76.7% commercial, 23.3% Medicare). The model was developed using progression-free survival (PFS), overall survival (OS), and ≥CR endpoints from CARTITUDE-4 over a period of 25.4 months. Inpatient stays, outpatient visits, drug acquisition, administration, and monitoring costs were included. The base-case model assumed an inpatient setting for each cilta-cel infusion; another scenario included 30% outpatient and 70% inpatient infusions. Costs of managing grade 3-4 adverse events (AEs) and grade 1-4 cytokine release syndrome and neurotoxicity were included. Subsequent therapy costs were incurred after disease progression; terminal care costs were considered upon death events. Outcomes included total cost per treated patient, total cost per complete responder, and cost per month in PFS between cilta-cel and SOC. Costs were adjusted to 2024 US dollars. Results: Total cost per treated patient, total cost per complete responder, and total cost per month in PFS were estimated at $704,641, $963,941, and $30,978 for cilta-cel, respectively, and $840,730, $3,856,559, and $42,520 for SOC over the 25.4-month period. Cost drivers included treatment acquisition costs before progression and subsequent treatment costs ($451,318 and $111,637 for cilta-cel; $529,795 and $265,167 for SOC). A scenario analysis in which 30% of patients received an outpatient infusion (assuming the same payer mix) showed a lower cost per complete responder for cilta-cel ($956,523) than those with an infusion in the inpatient setting exclusively. Discussion: This analysis estimated that cost per treated patient, cost per complete responder, and cost per month in PFS for cilta-cel were remarkably lower than for DPd or PVd, highlighting the substantial clinical and economic benefit of cilta-cel for patients with RRMM.

Thalidomide attenuates radiation-induced apoptosis and pro-inflammatory cytokine secretion in oral epithelial cells by promoting LZTS3 expression.

Radiation-induced oral mucositis (RIOM) is a prevalent oral complication that occurs in individuals undergoing radiotherapy or radiation treatment for head and neck tumors. The presence of oral mucosal rupture and ulcerative lesions, which are the defining features of this condition, can significantly affect the quality of life of patients. Additionally, it can interfere with tumor therapy and contribute to an unfavorable prognosis. Current evidence suggests that cellular inflammation and programmed cell death are important factors in disease development. Moreover, thalidomide (THD) has been revealed to reduce the incidence and severity of RIOM in patients undergoing chemoradiotherapy for nasopharyngeal carcinoma. However, the mechanism through which THD improves RIOM remains unknown. This study aimed to investigate the role of LZTS3 in RIOM by analyzing various sequencing datasets and conducting knockdown and overexpression experiments. We used small interfering RNA transfection and LZTS3 overexpression, followed by validation through polymerase chain reaction, western blotting, flow cytometry, and enzyme-linked immunosorbent assay. In this study, we identified LZTS3 as a potential target for THD regulation in RIOM. Through a series of experiments, we confirmed that LZTS3 has the ability to inhibit the inflammatory response and apoptosis of cells. In addition, we also found that THD can regulate the expression of LZTS3 by upregulating, thereby affecting inflammatory response and apoptosis. We repeated these results in a live animal model. In summary, THD has the potential to reduce the occurrence of oral mucositis in patients by upregulating LZTS3 levels. These findings provide a promising avenue for future drug research and development to treat RIOM.

Belantamab mafodotin, pomalidomide, and dexamethasone for triple class exposed/refractory relapsed multiple myeloma: a subgroup analysis of the ALGONQUIN trial.

Given the early use of triplet and quadruplet regimens, most patients with multiple myeloma (MM) will be exposed and/or refractory to PIs, IMiDs, and anti-CD38 mAbs after first- or second-line treatment. Effective treatment for this group of triple class exposed/refractory (TCE/R) patients is crucial. Here we present a post-hoc subgroup analysis of TCE/R patients treated on the ALGONQUIN study of belantamab mafodotin plus pomalidomide-dexamethasone (belamaf-Pd) for relapsed MM. Of the 99 patients treated on the ALGONQUIN study, 69 were TCE and 56 were TCR and were included in this analysis. Patients had a median of three prior lines of therapy. The ORR was 86.4% in TCE patients and 84.9% in TCR patients, with ≥ very good partial response rates of 64% and 68% respectively. The median progression free survival was 18.3 months in TCE patients and 19.6 months in TCR patients, with overall survival not yet reached and 34.4 months, respectively for TCE and TCR patients. No new safety signals were identified. The most common Grade ≥ 3 AEs were keratopathy (48%), decreased visual acuity (42%), neutropenia (36%), thrombocytopenia (27%), and infection (25%). In this subgroup analysis of the ALGONQUIN study, patients with TCE/TCR disease treated with belamaf-Pd achieved high clinical response rates with durable remissions, comparable to other novel therapeutics in this space.

Efficacy and safety of thalidomide for recurrent aphthous stomatitis: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is considered as the most common oral mucosal lesion affecting up to 25% of people worldwide. Thalidomide has been reported for the treatment of RAS, but the evidence has not been systematically evaluated. We first systematically reviewed the efficacy and safety of thalidomide for the treatment of RAS. METHODS: We searched The Cochrane Library, PubMed, Scopus, Web of Science, Embase, China National Knowledge Infrastructure (CNKI), Chinese BioMedical Literature Database (CBM), Wanfang Data, and VIP information from inception to December 2023. Randomized controlled trials (RCTs) comparing thalidomide with control for RAS were included in the analysis. The primary outcome were complete response and overall response, and the secondary outcome were recurrence interval (RI), ulcer number and size, healing time, visual analogue scale (VAS), immunological data, and adverse events. Meta-analysis was conducted using the Review Manager 5.4 software. RESULTS: Twenty-one trials involving 1668 patients were included in this review. The results of our meta-analysis showed that thalidomide significantly improved the complete response rate and overall response rate, prolonged the recurrence interval, accelerated the healing process, reduced the number and size of ulcers, and lowered TNF-α levels in the treatment of RAS. However, thalidomide significantly increases adverse events. RESULTS: Thalidomide has a significant benefit in the treatment of RAS. However, considering the potential side effects of thalidomide, it may be an optimal treatment option for major RAS patients or cases that do not respond to topical agents.

Acetyl-CoA Carboxylase Proteolysis-Targeting Chimeras: Conceptual Design and Application as Insecticides.

Novel approaches for pest control are essential to ensure a sufficient food supply for the growing global population. The development of new insecticides must meet rigorous regulatory requirements for safety and address the resistance issues of existing insecticides. Proteolysis-targeting chimeras (PROTACs), originally developed for human diseases, show promise in agriculture. They offer innovative insecticides tailored to overcome resistance, opening avenues for agricultural applications. In this study, we developed small-molecule degraders by incorporating pomalidomide as an E3 ligand. These degraders were linked to a ligand (spirotetratmat enol) targeting the ACC protein through a flexible chain, aiming to achieve the efficient control of insects. Compounds 9a-9d were designed, synthesized, and evaluated for biological activities and mechanisms. Among them, 9b exhibited superior potency against Aphis craccivora (LC50 = 107.8 µg mL-1) compared to others and effectively degraded ACC proteins through the ubiquitin-proteasome system. These findings highlight the potential of utilizing PROTAC-based approaches in the development of insecticides for efficient pest control.

Tofacitinib versus thalidomide for mucocutaneous lesions of systemic lupus erythematosus: A real-world CSTAR cohort study XXVII.

OBJECTIVE: Thalidomide is an effective medication for refractory mucocutaneous lesions of systemic lupus erythematosus (SLE) and can treat arthritis in some autoimmune diseases, but it has some adverse reactions. Recently, the effectiveness of tofacitinib in treating mucocutaneous lesions of SLE has been reported. We aimed to compare the efficacy and safety of tofacitinib with thalidomide in treating mucocutaneous and musculoskeletal lesions in patients with SLE. METHODS: This study was a real-world cohort study based on the Chinese SLE Treatment and Research group (CSTAR) registry. SLE patients who manifested mucocutaneous and/or musculoskeletal symptoms and were prescribed tofacitinib or thalidomide were included. We retrospectively conducted comparisons between the tofacitinib and thalidomide groups regarding clinical improvements, SLE disease activity, serological indicators, glucocorticoid doses, and adverse events at the 1, 3, and 6-months time points. RESULTS: At 3 and 6 months, the tofacitinib group exhibited a higher proportion of patients with improvement in mucocutaneous and musculoskeletal issues. Additionally, a greater percentage of patients in the tofacitinib group achieved remission or a low disease activity state (LLDAS) at these time points. No significant serological improvements were observed in either the tofacitinib or thalidomide groups. Fewer adverse events were observed in the tofacitinib group than in the thalidomide group. CONCLUSIONS: Tofacitinib might be superior to thalidomide in the improvement of mucocutaneous and musculoskeletal lesions in SLE, and had a good safety profile.

Multisite distribution of fibrillary inclusions in a patient with light chain proximal tubulopathy: A case report.

RATIONALE: Light chain proximal tubulopathy (LCPT) is a rare form of renal impairment associated with multiple myeloma (MM). LCPT is caused by inclusions formed of free light chains that are typically crystalline, but can also be noncrystalline structures. PATIENT CONCERNS: A 62-year-old man was hospitalized for the investigation of abnormal urine test results lasting for 1 year and kidney-function abnormalities persisting for more than 1 month. DIAGNOSES: Noncrystalline LCPT and MM. INTERVENTIONS: The patient was treated with the lenalidomide, bortezomib, and dexamethasone and pomalidomide, bortezomib, and dexamethasone chemotherapy regimens. OUTCOMES: Complete remission of MM was achieved, and the patient's renal function returned to normal. LESSONS: This case report highlights the importance of renal pathology in the diagnosis of patients with unexplained chronic kidney disease and proteinuria.

Efficacy of CARVYKTI in CARTITUDE-4 versus other conventional treatment regimens for lenalidomide-refractory multiple myeloma using inverse probability of treatment weighting.

Aim: The phase III randomized controlled trial (RCT) CARTITUDE-4 (NCT04181827) demonstrated superiority of CARVYKTI (ciltacabtagene autoleucel; cilta-cel) over daratumumab, pomalidomide and dexamethasone (DPd) and pomalidomide, bortezomib and dexamethasone (PVd) for relapsed/refractory multiple myeloma (RRMM) patients who have received one to three prior line(s) of therapy (LOT[s]) including an immunomodulatory agent and a proteasome inhibitor, and are refractory to lenalidomide. These analyses estimate the relative efficacy between cilta-cel and other common treatment regimens, for which no direct comparative evidence is available. Materials & methods: Patient data were available from the CARTITUDE-4, CASTOR, CANDOR and APOLLO RCTs. Imbalances between cohorts on key patient characteristics were adjusted for using inverse probability of treatment weighting (IPTW). Relative efficacies were estimated with response rate ratios (RRs) and 95% confidence intervals (CIs) for overall response rate (ORR), very good partial response or better rate (≥VGPR) and complete response or better rate (≥CR), and with hazard ratios (HRs) and 95% CIs for progression-free survival (PFS). Sensitivity analyses using different analytical methods and additional covariates were explored. Results: Key characteristics were well balanced across cohorts after IPTW. Cilta-cel showed statistically significant benefit in PFS (HRs: 0.11-0.51), ≥VGPR (RRs: 1.51-5.13) and ≥CR (RRs: 2.90-35.24) versus all comparators, and statistically significant improvements in ORR over most comparator regimens (RRs: 1.22-1.90). Results were consistent across sensitivity analyses. Conclusion: Cilta-cel demonstrated benefit over other common treatment regimens, highlighting its potential to become a new standard of care option for lenalidomide-refractory RRMM patients with one to three prior LOT(s). These comparisons help to demonstrate the improved efficacy of cilta-cel in countries where the standard of care may differ from DPd/PVd.

Transfusion independence after lenalidomide discontinuation in patients with del(5q) myelodysplastic neoplasm: a HARMONY Alliance study.

Lenalidomide (LEN) can induce red blood cell-transfusion independence (RBC-TI) in 60-70% of del(5q) myelodysplastic neoplasm (MDS) patients. Current recommendation is to continue LEN in responding patients until failure or progression, with likelihood of toxicity and a high cost for healthcare systems. This HARMONY Alliance study investigated the outcome of MDS del(5q) patients who discontinued LEN while RBC-transfusion independent. We enrolled 118 patients with IPSS-R low-intermediate risk. Seventy patients (59%) discontinued LEN for intolerance, 38 (32%) per their physician decision, nine (8%) per their own decision and one (1%) for unknown reasons. After a median follow-up of 49 months from discontinuation, 50/118 patients lost RBC-TI and 22/30 who underwent cytogenetic re-evaluation lost complete cytogenetic response. The median RBC-TI duration was 56 months. In multivariate analysis, RBC-TI duration after LEN discontinuation correlated with low transfusion burden before LEN therapy, treatment ≥ 12 LEN cycles, younger age and higher Hb level at LEN withdrawal. Forty-eight patients were re-treated with LEN for loss of response and 28 achieved again RBC-TI. These data show that stopping LEN therapy in MDS del(5q) patients who reached RBC-TI allows prolonged maintenance of TI in a large subset of patients.

[Phosphodiesterase 4 inhibitors in dermatology : Role in the treatment of skin diseases]. / Phosphodiesterase-4-Inhibitoren in der Dermatologie : Die Rolle in der Behandlung von Hautkrankheiten.

BACKGROUND: Chronic inflammatory skin diseases are of great social and medical importance and require effective drug therapy. Phosphodiesterase 4 (PDE4) inhibitors represent a possible therapeutic option by regulating inflammatory processes. PDEs cause the release of proinflammatory cytokines by interfering with signaling pathways. The PDE4 inhibitors apremilast (treatment of psoriasis and Behçet's disease), roflumilast (treatment of chronic obstructive pulmonary disease), and crisaborole (treatment of atopic dermatitis) are currently approved in Europe. PSORIASIS: Apremilast is used for second-line treatment of plaque psoriasis and psoriatic arthritis and has a favorable side effect profile. Topical PDE4 inhibitors are currently being researched and have not yet been approved by the European Medicines Agency (EMA). ATOPIC DERMATITIS: The topical PDE4 inhibitor crisaborole was approved by the EMA in 2020 as a topical treatment alternative to glucocorticoids and calcineurin inhibitors. Although the substance has shown good tolerability in studies and also alleviates the accompanying itching, it did not find its way onto the German market. BEHçET'S DISEASE: Apremilast is approved for the treatment of Behçet's disease in adults with refractory, severe oral ulcers. OUTLOOK: Case studies have also demonstrated the efficacy of systemic PDE4 inhibition in other skin diseases (including blistering autoimmune dermatoses, lichen planus, and acantholytic genodermatoses). The substances are also being researched and used to treat extracutaneous inflammatory diseases.

The TGFß type I receptor kinase inhibitor vactosertib in combination with pomalidomide in relapsed/refractory multiple myeloma: a phase 1b trial.

Functional blockade of the transforming growth factor-beta (TGFß) signalling pathway improves the efficacy of cytotoxic and immunotherapies. Here, we conducted a phase 1b study (ClinicalTrials.gov., NCT03143985) to determine the primary endpoints of safety, tolerability, and maximal tolerated dose (200 mg twice daily) for the orally-available TGFß type I receptor kinase inhibitor vactosertib in combination with pomalidomide in relapsed and/or refractory multiple myeloma (RRMM) patients who had received ≥2 lines of chemoimmunotherapy. Secondary endpoints demonstrated sustained clinical responses, favorable pharmacokinetic parameters and a 6-month progression-free survival of 82%. Vactosertib combined with pomalidomide was well-tolerated at all dose levels and displayed a manageable adverse event profile. Exploratory analysis indicated that vactosertib co-treatment with pomalidomide also reduced TGFß levels in patient bone marrow as well as the level of CD8+ T-cells that expressed the immunoinhibitory marker PD-1. In vitro experiments indicated that vactosertib+pomalidomide co-treatment decreased the viability of MM cell lines and patient tumor cells, and increased CD8+ T-cell cytotoxic activity. Vactosertib is a safe therapeutic that demonstrates tumor-intrinsic activity and can overcome immunosuppressive challenges within the tumor microenvironment to reinvigorate T-cell fitness. Vactosertib offers promise to improve immunotherapeutic responses in heavily-pretreated MM patients refractory to conventional agents.

Thalidomide and Hydroxyurea in Transfusion-Dependent Thalassemia: Efficacy, Safety Profile and Impact on Quality of Life.

Transfusion-dependent thalassemia (TDT) is a major public health concern in India, requiring regular transfusions for survival. There is also significant morbidity caused by iron overload and transfusion related infections. Novel therapies targeting fetal hemoglobin induction are the need of the hour in resource-poor institutions for patients where transplant is not feasible for various reasons. This single arm, non-randomised prospective trial evaluated the efficacy and safety of a combination of low dose thalidomide and hydroxyurea in TDT along with the impact on quality of life (QoL). It included 41 TDT patients, who failed a reasonable trial of hydroxyurea. Complete response (CR) was defined as transfusion independence and partial response (PR) denoted at least a 50% reduction in transfusion requirement. The rest were defined as non-responders (NR). The mean age of the cohort was 20.78 years (range 12-45 years). There were 13 males and 28 females. Nineteen (46.3%), 7 (17.1%), and 15 (36.6%) patients achieved CR, PR, and no response respectively. The overall response rate (CR + PR) was 63.4%. There was a significant increase in hemoglobin levels with decrement in transfusion burden and ferritin levels. There were no significant adverse reactions. No significant predictors of response were found including amongst genetic modifiers. It improved the health related QoL amongst responders. The combination of thalidomide and hydroxyurea appear safe and effective in the reduction in transfusion requirement of TDT patients. The judicious use of these drugs can improve the quality of life and pave the way for patients not eligible for a stem cell transplant.

Real-world treatment patterns and outcomes in relapsed/refractory multiple myeloma (1-3 prior lines): Flatiron database.

ABSTRACT: In the context of multiple myeloma (MM), early use of the immunomodulatory drug lenalidomide has led to an increased population of patients with lenalidomide-refractory MM in early-line settings, but their outcomes are not well characterized. Herein, we report treatment patterns, survival outcomes, prognostic variables, and attrition rates for patients with proteasome inhibitor-exposed, lenalidomide-refractory MM, treated with 1 to 3 prior lines of therapy (LOT). From 12 767 patients with MM in the Flatiron Health database between January 2016 and April 2022, 1455 met the inclusion criteria. The most common subsequent treatments were triplet combinations (41.6% of patients); daratumumab/pomalidomide/dexamethasone was the most common treatment regimen (13.2%). Median real-world progression-free survival (RW-PFS) and overall survival (OS) were 6.5 months and 44.4 months, respectively. RW-PFS was similar in patients with 1, 2, or 3 prior LOT. International Staging System stage III, Eastern Cooperative Oncology Group performance status of 1, hemoglobin <12 g/dL, high-risk cytogenetics, and refractoriness to anti-CD38 antibody at baseline were associated with worse RW-PFS and OS. Outcomes remained similar for patients who received National Comprehensive Cancer Network-preferred treatments and those who received treatments after 2020. In 561 patients with 1 prior LOT at inclusion, the cumulative attrition rate from LOT 2 to 5 was 85%, which included 25% patients who died and 60% with no further treatment. Patients with lenalidomide-refractory MM who have received 1 to 3 prior LOT have poor outcomes and progress rapidly through available therapies, highlighting the need for more effective treatments early in the disease course, before patients are lost to attrition.

Exploring Degradation of Intrinsically Disordered Protein Yes-Associated Protein Induced by Proteolysis TArgeting Chimeras.

Yes-associated protein (YAP) is a key oncogene in the Hippo tumor suppression pathway, historically challenging to target due to its intrinsically disordered nature. Leveraging recent advances in high-throughput screening that identified several YAP binders, we employed proteolysis-targeting chimera technology to develop a series of YAP degraders. Utilizing NSC682769, a known YAP binder, linked with VHL ligand 2 or pomalidomide via diverse linkers, we synthesized degraders including YZ-6. This degrader not only recruits the E3 ligase VHL for the rapid and sustained degradation of YAP but also effectively inhibits its nuclear localization, curtailing YAP/TEAD-mediated transcription in cancer cell lines such as NCI-H226 and Huh7. This dual action significantly diminishes YAP's oncogenic activity, contributing to the potent antiproliferative effects observed both in vitro and in a Huh7 xenograft mouse model. These results underscore the potential of PROTAC-mediated YAP degradation as a strategy for treating YAP-driven cancers.

[Durable remission with lenalidomide in a patient with early relapse of adult T-cell leukemia/lymphoma after cord blood transplantation].

A 62-year-old woman with adult T-cell leukemia/lymphoma (ATL) received umbilical cord blood transplantation (CBT) in first complete remission. However, relapse of ATL was detected on day 74 post-transplantation, as evidenced by the rapid growth of lymphoma cells in peripheral blood and an increase in soluble interleukin-2 receptor (sIL2R) levels. Discontinuation of immunosuppressant therapy alone did not improve ATL findings, but treatment with lenalidomide caused lymphoma cells to disappear from the peripheral blood and sIL2R levels to return to normal. Pancytopenia was observed as a lenalidomide-associated adverse effect, but lymphocyte counts were not reduced. The patient was judged to be in complete remission based on results of Southern blot analysis and human T-cell leukemia virus 1 (HTLV-1)-infected cell analysis using flow cytometry (HAS-Flow). Flow cytometric analysis of peripheral blood and FISH analysis of X and Y chromosomes revealed that the therapeutic effect of lenalidomide was associated with an increase in the number of donor-derived peripheral natural killer cells. ATL relapse was not observed at 13 months into lenalidomide treatment. Our results suggest that lenalidomide is an effective option for the treatment of post-transplant relapsed ATL.

OtezlaTM (Apremilast 30-Mg Tablets).

OtezlaTM was first approved on March 21, 2014 for the treatment of psoriatic arthritis, on September 23, 2014 for moderate to severe plaque psoriasis and on July 19, 2019 for the treatment of oral ulcers associated with Behcet's disease (BD). Apremilast is an inhibitor of phosphodi-esterase-4, an enzyme involved in the pathogenesis of several dermatologic conditions. This review explores the potential utility of apremilast in the treatment of other unapproved dermatologic indications.
