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.

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.

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.

Low dose lenalidomide versus placebo in non-transfusion dependent patients with low risk, del(5q) myelodysplastic syndromes (SintraREV): a randomised, double-blind, phase 3 trial.

BACKGROUND: Lenalidomide is the standard of care for patients who are transfusion dependent with chromosome 5q deletion (del[5q]) myelodysplastic syndromes. In the SintraREV trial, we aimed to investigate whether an early intervention of low lenalidomide doses for 2 years could delay transfusion dependency in patients with anaemia who were not transfusion dependent. METHODS: This randomised, double-blind, phase 3 trial, was conducted at 22 sites (University Hospitals) in Spain, France, and Germany. Eligible patients were aged 18 years or older diagnosed with low-risk or intermediate-1-risk del(5q) myelodysplastic syndromes with non-transfusion-dependent anaemia (according to the IPSS), were erythropoietin-stimulating agents naive, and had an ECOG performance status of 2 or less. Patients were randomly assigned (2:1) by means of a telephone system to receive lenalidomide 5 mg daily in 28-day cycles versus placebo for 2 years. The primary endpoint was time to transfusion dependency based on blinded independent central review. Analysis were by intent-to-treat (ITT) and evaluable population. Safety analyses included all participants who received at least one dose of treatment. This trial is registered with ClinicalTrials.gov (NCT01243476) and EudraCT (2009-013619-36) and is complete. FINDINGS: Between Feb 15, 2010, and Feb 21, 2018, 61 patients were randomly assigned to receive lenalidomide (n=40; two did not receive treatment) or placebo (n=21). The median age was 72·2 (IQR 65·4-81·9) years, 50 (82%) patients were female, and 11 (18%) were male. The median follow-up time was 60·6 (IQR 32·1-73·9) months. Regarding primary endpoint, median time to transfusion dependency was not reached (95% CI not applicable) in the lenalidomide group versus 11·6 months (95% CI 0·00-30·11) in the placebo group (p=0·0027). Lenalidomide significantly reduced the risk of transfusion dependency by 69·8% (hazard ratio 0·302, 95% CI 0·132-0·692; p=0·0046). The most frequent treatment-related adverse event was neutropenia, occurring in 24 (63%) of 38 patients in the lenalidomide group (grade 3 and 4 in 17 [45%] patients and one [3%], respectively) and in four (19%) of 21 patients in the placebo group (grade 3 in one [5%] patient). Thrombocytopenia was detected in seven (18%) of 38 patients receiving lenalidomide (grade 3 in two [5%] patients). Regarding the non-haematological toxicity, skin disorders (rash nine [23%] of 38 patients) were the most frequently described toxicities among patients receiving lenalidomide, being grade 3 in one (3%) of 38 patients. 19 serious adverse events were reported in 13 patients, 18 in the lenalidomide group and one in the placebo group, five of which were potentially related to the study drug. No treatment-related deaths were identified. INTERPRETATION: An early approach with low doses of lenalidomide across two years delays the time to transfusion dependency and improves the rate and quality of the responses, with a manageable safety profile in patients who are non-transfusion dependent with del(5q) low-risk myelodysplastic syndromes.

Risk of neutropenia in psoriasis patients prescribed anti-IL-23 antibody in comparison with anti-IL-17 antibody or adalimumab based on real-world data from the MID-NET® in Japan.

BACKGROUND: To evaluate the risk of neutropenia during treatment with anti-IL-23 antibodies in patients with psoriasis. METHOD: We conducted an observational study with cohort design using MID-NET® in Japan. We identified patients with psoriasis who were newly prescribed anti-IL-23 antibodies, anti-IL-17-antibodies, adalimumab, or apremilast between January 1, 2009, and March 31, 2021. We estimated the adjusted hazard ratio (aHR) of anti-IL-23 antibodies compared to that of anti-IL-17 antibodies, adalimumab, or apremilast, for the risk of grade 2 (neutrophil count < 1,500/µL) or grade 3 (neutrophil count < 1,000/µL) neutropenia. RESULTS: Overall, 287 patients on anti-IL-23 antibodies, 189 patients on anti-IL-17 antibodies, 293 patients on adalimumab, and 540 patients on apremilast were included. Compared with anti-IL-17 antibodies, the aHR (95% confidence interval (CI)) of anti-IL-23 antibodies was 0.83 (0.27-2.51) for grade 2 and 0.40 (0.02-7.60) for grade 3 neutropenia; that when compared with adalimumab was 0.76 (0.28-2.06) for grade 2 but was not calculated for grade 3 as no cases were found; and that compared with apremilast was 3.88 (0.62-24.48) for grade 2 and 0.43 (0.02-11.63) for grade 3 neutropenia. CONCLUSION: No clear increase in the risk of neutropenia with anti-IL-23 antibodies was observed.

Belantamab Mafodotin, Pomalidomide, and Dexamethasone in Multiple Myeloma.

BACKGROUND: Triplet or quadruplet therapies incorporating proteasome inhibitors, immunomodulators, and anti-CD38 antibodies have led to prolonged survival among patients with newly diagnosed multiple myeloma; however, most patients have a relapse. Frontline lenalidomide therapy has increased the number of patients with lenalidomide-refractory disease at the time of the first relapse. METHODS: In this phase 3, randomized, open-label trial, we evaluated belantamab mafodotin, pomalidomide, and dexamethasone (BPd), as compared with pomalidomide, bortezomib, and dexamethasone (PVd), in lenalidomide-exposed patients who had relapsed or refractory myeloma after at least one line of therapy. The primary end point was progression-free survival. Disease response and safety were also assessed. RESULTS: A total of 302 patients underwent randomization; 155 were assigned to the BPd group, and 147 to the PVd group. At a median follow-up of 21.8 months (range, <0.1 to 39.2), the 12-month estimated progression-free survival with BPd was 71% (95% confidence interval [CI], 63 to 78), as compared with 51% (95% CI, 42 to 60) with PVd (hazard ratio for disease progression or death, 0.52; 95% CI, 0.37 to 0.73; P<0.001). Data on overall survival were immature. The percentage of patients with a response to treatment (partial response or better) was 77% (95% CI, 70 to 84) in the BPd group and 72% (95% CI, 64 to 79) in the PVd group; 40% (95% CI, 32 to 48) and 16% (95% CI, 11 to 23), respectively, had a complete response or better. Grade 3 or higher adverse events occurred in 94% of the patients in the BPd group and 76% of those in the PVd group. Ocular events occurred in 89% of the patients who received BPd (grade 3 or 4 in 43%) and 30% of those who received PVd (grade 3 or 4 in 2%); ocular events in the BPd group were managed with belantamab mafodotin dose modification. Ocular events led to treatment discontinuation in 9% of the patients in the BPd group and in no patients in the PVd group. CONCLUSIONS: Among lenalidomide-exposed patients with relapsed or refractory myeloma, BPd conferred a significantly greater benefit than PVd with respect to progression-free survival, as well as deeper, more durable responses. Ocular events were common but were controllable by belantamab mafodotin dose modification. (Funded by GSK; DREAMM-8 ClinicalTrials.gov number, NCT04484623; EudraCT number, 2018-004354-21.).

Trends in Use and Evidence of Adherence to Risk Evaluation and Mitigation Strategy Pregnancy Testing Requirements for Thalidomide, Lenalidomide, and Pomalidomide in the USA, 2000-2020.

INTRODUCTION: Lenalidomide, pomalidomide, and thalidomide are effective treatments for multiple myeloma but are teratogenic. To mitigate this risk, the US Food and Drug Administration (FDA) required risk evaluation and mitigation strategy (REMS) programs for these drugs, which include pregnancy testing among women of childbearing potential-twice before initiation, weekly in the first month on treatment, and every 2-4 weeks thereafter. OBJECTIVE: We evaluated dispensing trends of lenalidomide, pomalidomide, and thalidomide and assessed adherence to REMS pregnancy testing requirements among at-risk patients taking these drugs. METHODS: Using three US health insurance claims databases (Optum Clinformatics® [2004-2020], Merative Marketscan [2003-2019], and Medicaid [2000-2018]), we assessed monthly use of the drugs, patient characteristics and treatment persistence among drug initiators, and claims-based evidence for adherence to pregnancy testing requirements among initiators with child-bearing potential. RESULTS: Lenalidomide was the most prescribed agent following its approval in 2006 and through the end of the study period. A total of 48,311 lenalidomide (mean age = 59 years [standard deviation (SD) = 16]), 17,550 thalidomide (mean age = 65 years [SD = 12]), and 6560 pomalidomide initiators (mean age = 65 years [SD = 11]) were identified; 45% of initiators of each drug were women. Among initiators under follow-up on day 90, 70% were still on therapy. Initiators of childbearing potential comprised 3% (N = 1,920) of all initiators; among this cohort, 12% had evidence in claims data of two pregnancy tests before initiation, and 9% with at least 33 days of follow-up of four tests during the first month of treatment. By contrast, 52% who received a refill had claims-based evidence of a pregnancy test within 7 days of dispensing. CONCLUSION: Although most patients who initiated lenalidomide, pomalidomide, and thalidomide were not of child-bearing potential, further investigation into actual non-adherence to pregnancy testing is needed.

Lenalidomide or Thalidomide for Transplant-Ineligible Patients With Newly Diagnosed Multiple Myeloma? An Overview of Systematic Reviews.

OBJECTIVES: To present an overview of evidence of efficacy, safety, and health-related quality of life of lenalidomide or thalidomide for transplant-ineligible multiple myeloma. METHODS: A literature search was performed in 5 databases until July 2022. We included systematic reviews with network meta-analyses of randomized controlled trials on the use of lenalidomide compared with thalidomide for transplant-ineligible multiple myeloma. The A Measurement Tool to Assess Systematic Reviews 2 was used to appraise the quality of included reviews. The results were focused on the lenalidomide + dexamethasone until disease progression (RDc) versus thalidomide + dexamethasone until disease progression (TDc) and induction with melphalan + prednisone + lenalidomide, followed by maintenance with lenalidomide (MPR-R) versus induction with melphalan + prednisone + thalidomide, followed by maintenance with thalidomide (MPT-T) regimens. RESULTS: Nine studies were included. Only 1 study did not show any weakness in critical domains of A Measurement Tool to Assess Systematic Reviews 2. For overall survival, RDc proved to be superior to TDc; however, no study showed significant difference between MPR-R and MPT-T. For progression-free survival, 2 of 3 studies showed that RDc is better than TDc; however, no difference between MPR-R and MPT-T was found. Regarding safety, these lenalidomide-based regimens had a lower risk for neurologic adverse events, with an increased risk of hematologic adverse events. No health-related quality of life meta-analyses were found. CONCLUSIONS: These findings suggest that, in terms of efficacy and safety, lenalidomide-based regimen is a good option for treatment of transplant-ineligible multiple myeloma in the public health system of Brazil, especially for those patients who develop severe neuropathy with thalidomide.

Elotuzumab plus pomalidomide and dexamethasone in relapsed/refractory multiple myeloma: Extended follow-up of a multicenter, retrospective real-world experience with 321 cases outside of controlled clinical trials.

The ELOQUENT-3 trial demonstrated the superiority of the combination of elotuzumab, pomalidomide, and dexamethasone (EloPd) in terms of efficacy and safety, compared to Pd in relapsed/refractory multiple myeloma (RRMM), who had received at least two prior therapies, including lenalidomide and a proteasome inhibitor. The present study is an 18-month follow-up update of a previously published Italian real-life RRMM cohort of patients treated with EloPd. This revised analysis entered 319 RRMM patients accrued in 41 Italian centers. After a median follow-up of 17.7 months, 213 patients (66.4%) experienced disease progression or died. Median progression-free survival (PFS) and overall survival (OS) were 7.5 and 19.2 months, respectively. The updated multivariate analysis showed a significant reduction of PFS benefit magnitude both in advanced International Staging System (ISS) (II and III) stages and previous exposure to daratumumab cases. Instead, advanced ISS (II and III) stages and more than 2 previous lines of therapy maintained an independent prognostic impact on OS. Major adverse events included grade three-fourths neutropenia (24.9%), anemia (13.4%), lymphocytopenia (15.5%), and thrombocytopenia (10.7%), while infection rates and pneumonia were 19.3% and 8.7%, respectively. A slight increase in the incidence of neutropenia and lymphocytopenia was registered with longer follow-up. In conclusion, our real-world study still confirms that EloPd is a safe and possible therapeutic choice for RRMM. Nevertheless, novel strategies are desirable for those patients exposed to daratumumab.

A retrospective analysis of drugs associated with the development of cutaneous squamous cell carcinoma reported by patients on the FDA's adverse events reporting system.

Cutaneous squamous cell carcinoma (cSCC) is the second most common type of skin cancer arising from squamous cells of the epidermis. Most cases of cSCC have a good prognosis if detected and treated early; however, certain cases can be aggressive. The primary risk factor for cSCC is prolonged ultraviolet radiation from sun exposure, leading to DNA mutations. Other risk factors have also been observed, including adverse reactions to medications, particularly immunosuppressants. A query of the Food and Drug Administration Adverse Events Reporting System (FAERS) was done, and all reported events of cSCC as adverse events to medication were recorded along with demographic data of patients affected. A total of 4,792 cases of cSCC as an adverse event to medication were reported between 1997 and 2023. Lenalidomide, a chemotherapeutic drug, had the most cases of cSCC as an adverse event. Nine of the top 10 drugs associated with cSCC had immunosuppressive characteristics. While males had higher odds of cSCC associated with corticosteroids and calcineurin inhibitors, females had higher odds of cSCC related to monoclonal antibodies. Geriatric patients accounted for the majority of cSCC cases at 59.7%. Drawing on data from the FAERS database, there's been a consistent increase in cSCC cases as a side-effect to certain medications, with most having immunosuppressive characteristics. Since there is a lack of up-to-date literature overviewing the most implicated medications for cSCC, we aimed to illustrate this better, as well as patient demographics, to better guide clinicians when prescribing these medications.

[A case of hematogenous disseminated tuberculosis in a patient with contradictory reactions treated with thalidomide].

Here we reported a case of a 52-year-old male with a 13-year history of Crohn's disease who developed disseminated tuberculosis after 2 injections of infliximab. The patient was admitted with a chief complaint of fever with headache of 1 month's duration. Mycobacterium tuberculosis DNA was found positive in cerebrospinal fluid and lavage fluid by lumbar puncture and bronchoscopy. He was diagnosed with tuberculous meningitis, pulmonary tuberculosis, tracheobronchial tuberculosis and lymph node tuberculosis. After treatment with anti-tuberculosis and glucocorticoids, the symptoms did not improve, the lesions progressed, and granulomas were formed in the tracheobronchial lumen. These were considered to be contradictory reactions and thalidomide was given together with glucocorticoids. The patient's clinical condition has improved significantly. Treatment was successfully completed after 18 months with 1 HREZLfxLzd/8 HEZCsLzd/1 HEZCs/8 HZCs.

Safety and effectiveness of apremilast in Japanese patients with psoriatic disease: Results of a post-marketing surveillance study.

The safety and efficacy of apremilast in psoriatic disease has been demonstrated in clinical trials, including in Japanese patients. This post-marketing surveillance study was conducted after approval of apremalast in Japan in 2016 to evaluate the safety and effectiveness of the drug in Japanese patients with plaque psoriasis (PsO) and psoriatic arthritis (PsA) in routine clinical practice. Patients (enrolled between September 1, 2017, and August 31, 2019), were observed for 12 months after apremilast treatment initiation or until discontinuation or withdrawal. Safety was assessed by evaluating adverse reactions (ARs) and serious ARs. Effectiveness measures in PsO included the proportion of patients who achieved global improvement and Physician's Global Assessment (PGA) scores of 0/1 and the change from baseline in the Dermatology Life Quality Index (DLQI) after 6 and 12 months treatment. The safety analysis set included 1063 patients (PsO, n = 992; PsA, n = 127). ARs and serious ARs were reported in 29.4% and 0.7% of patients, respectively; most occurred <1 month after apremilast initiation. There were no reports of fatal ARs, serious infections, hypersensitivity, or vasculitis. No new safety signals were identified. Among the key survey items, gastrointestinal disorders were the most common ARs (21.3%). In patients with PsO, after 6 and 12 months of treatment, effectiveness rates of achieving highly effective or effective global improvement of were 90.9% and 93.8%; PGA 0/1 was achieved by 42.7% and 58.1% of patients; mean decrease from baseline in total DLQI score was 4.2 (p < 0.0001) and 5.7 (p < 0.0001), respectively. Effectiveness was evaluated in a small number of patients with PsA for some measures; after 6 and 12 months of treatment, improvements were observed in global improvement effectiveness rates, Disease Activity Score in 28 Joints score, Visual Analog Scale score, and DLQI score. We conclude that orally administered apremilast was well tolerated and effective in Japanese patients with PsO and/or PsA enrolled in this post-marketing surveillance study.

Was thalidomide a placebo hypnotic?

Six decades ago the world learned that thalidomide, a seemingly non-toxic sedative and hypnotic, caused severe birth defects including the flipper-like deformity of the arms known as phocomelia. When thalidomide was tested against placebo by the trialist Louis Lasagna in 1960 (while the drug was banned from the U.S. marketplace), he found the 100-mg dosage equivalent to placebo, as well as greatly inferior to the 200-mg dosage, in producing sleep. Even as these findings were made known, a 100-mg dose of thalidomide was in general use as a sleep aid for pregnant women. It appears that unbeknownst to themselves, an untold number of pregnant women around the world who were prescribed thalidomide incurred the risks of a teratogen in return for the benefits of a sugar pill.

Isatuximab with pomalidomide-dexamethasone in relapsed/refractory multiple myeloma: post-marketing surveillance in Japan.

This post-marketing surveillance assessed the safety and effectiveness of isatuximab plus pomalidomide and dexamethasone (Isa-Pd) for relapsed or refractory multiple myeloma (RRMM) during real-world use in Japan. Data from 211 individuals with RRMM treated with Isa-Pd in Japan between October 2020 and October 2021 were collected, with follow-up for up to 12 months after initiation of Isa-Pd or until treatment discontinuation. The incidence of adverse drug reactions (ADRs), ADRs of special interest (infusion reactions, bone marrow suppression, infections, cardiac disorders, other ADRs of Grade ≥ 3), and serious ADRs was assessed. Best overall response and overall response rate (ORR) were determined. In the safety analysis set (n = 120), ADR incidence was 57.5%. Most ADRs were hematologic, and serious ADRs occurred in 28.3%. Bone marrow suppression occurred in 46.7% of participants (19.2% serious), infusion reactions in 18.3% (6.7% serious), infections in 11.7% (8.3% serious), and a serious cardiac disorder in one participant; other Grade ≥ 3 ADRs were reported in 3.3% (1.7% serious). In the effectiveness analysis set (n = 108), the most common best overall response was very good partial response (24.1%), and ORR was 51.9%. These findings support the safety and effectiveness of Isa-Pd for RRMM in real-life settings in Japan.

The efficacy and tolerability of bortezomib, thalidomide, and dexamethasone induction therapy with a thalidomide dose step-up strategy in patients with newly diagnosed multiple myeloma: A prospective observational study.

BACKGROUND: Thalidomide-containing regimens cause adverse events (AEs) that may require a reduction in treatment intensity or even treatment discontinuation in patients with multiple myeloma. As thalidomide toxicity is dose-dependent, identifying the most appropriate dose for each patient is essential. AIMS: This study aimed to investigate the effects of a thalidomide dose step-up strategy on treatment response and progression-free survival (PFS). METHODS AND RESULTS: This prospective observational study included 93 patients with newly diagnosed multiple myeloma (NDMM) who received bortezomib, thalidomide, and dexamethasone (VTD). The present study assessed the incidence of thalidomide dose reduction and discontinuation, the overall dose intensity, and their effects on therapeutic efficacy. Furthermore, this study used Cox proportional hazard models to analyze the factors contributing to thalidomide intolerability. The results showed the overall response rates in all patients and the evaluable patients were 78.5% and 98.7%, respectively. The median PFS in the study cohort was not reached. The most common thalidomide-related AEs were constipation (32.3%) and skin rash (23.7%), resulting in dose reduction and discontinuation rates of 22.6% and 21.5%, respectively. The responders had a significantly higher average thalidomide dose intensity than the nonresponders (88.6% vs. 42.9%, p < .001). CONCLUSION: The thalidomide dose step-up approach is a viable option for patients with NDMM receiving VTD induction therapy with satisfactory efficacy and tolerability. However, thalidomide intolerance may lead to dose reduction or discontinuation due to unpredictable AEs, leading to lower dose intensity and potentially inferior treatment outcomes. In addition to a dose step-up strategy, optimal supportive care is critical for patients with multiple myeloma receiving VTD induction therapy.

Safety and efficacy of thalidomide in treatment of gastrointestinal bleeding secondary to angioectasias: a systematic review and meta-analysis.

BACKGROUND: Thalidomide has been used for angioectasia-associated refractory gastrointestinal bleeding (GIB), with studies showing variable efficacy and side effects profile. We conducted a meta-analysis to reconcile the data. METHODS: Online databases were searched for studies evaluating thalidomide in patients with refractory/recurrent GIB due to angioectasias. The outcomes of interest were cessation of bleeding, rebleeding, need for blood transfusion, hospitalization and adverse events. Pooled proportions for incidence, and odds ratios (OR) for comparison with control were calculated along with 95% confidence interval (CI). RESULTS: A total of seven studies with 346 patients (n = 269 thalidomide, n = 77 control) were included. Thalidomide dose was usually started at 50-100mg/day. The mean age was 65 years, 45% patients were men, and mean follow-up was 1.8 years. The pooled clinical outcomes with thalidomide were: cessation of bleeding 42.2% (95% CI 36.02 to 48.41), rebleeding 30%, need for blood transfusion 20.1%, hospitalization 40% and adverse events 55.9%. When compared with the control group in 2 studies, patients on thalidomide had significantly higher odds of cessation of bleeding (OR 21.40, 95% CI 5.78 to 79.29, p < 0.00001) and adverse events, with lower need for blood transfusion and hospitalization. DISCUSSION: In patients with angioectasias-related refractory/recurrent GIB, the use of thalidomide results in significantly decreased bleeding risk and may play a role in the management of such patients.

An open-label phase 2 study treating patients with first or second relapse of multiple myeloma with carfilzomib, pomalidomide, and dexamethasone (KPd): SELECT study.

Once-weekly carfilzomib at 56 mg/m2 plus immunomodulatory drugs and dexamethasone has shown efficacy and tolerability treating early relapsed/refractory multiple myeloma (RRMM). The phase 2 SELECT study (NCT04191616) evaluated efficacy/safety of weekly carfilzomib, pomalidomide, and dexamethasone (KPd) in early RRMM patients refractory to lenalidomide. All 52 treated patients were refractory to prior treatment, and 19 (37%) were triple-class refractory. Overall response rate (ORR; primary endpoint) was 58% (35% ≥ very good partial response, 6% ≥ complete response); median response duration was 20.3 months. Minimal residual disease negativity (10-5) was achieved in 10% of patients. Median progression-free survival was 11.1 months; median overall survival was 18.8 months. Adverse events (AEs) were consistent with the known safety profile including grade ≥3 treatment-emergent AEs reported in 67% of patients. Although the primary endpoint of ORR was not met, KPd showed meaningful clinical benefits in lenalidomide-refractory RRMM patients, including those who were daratumumab-refractory and/or triple-class refractory.

Full Guidelines-From the Medical Board of the National Psoriasis Foundation: Perioperative management of systemic immunomodulatory agents in patients with psoriasis and psoriatic arthritis.

BACKGROUND: Systemic immunomodulatory agents are indicated in the treatment of moderate-to-severe plaque psoriasis and psoriatic arthritis. Perioperative use of these medications may increase the risk of surgical site infection (SSI) and complication. OBJECTIVE: To evaluate the risk of SSI and complication in patients with chronic autoimmune inflammatory disease receiving immunomodulatory agents (tumor necrosis factor-alfa [TNF-α] inhibitors, interleukin [IL] 12/23 inhibitor, IL-17 inhibitors, IL-23 inhibitors, cytotoxic T-lymphocyte-associated antigen-4 costimulator, phosphodiesterase-4 inhibitor, Janus kinase inhibitors, tyrosine kinase 2 inhibitor, cyclosporine (CsA), and methotrexate [MTX]) undergoing surgery. METHODS: We performed a search of the MEDLINE PubMed database of patients with chronic autoimmune inflammatory disease on immune therapy undergoing surgery. RESULTS: We examined 48 new or previously unreviewed studies; the majority were retrospective studies in patients with rheumatoid arthritis and inflammatory bowel disease. CONCLUSION: For low-risk procedures, TNF-α inhibitors, IL-17 inhibitors, IL-23 inhibitors, ustekinumab, abatacept, MTX, CsA, and apremilast can safely be continued. For intermediate- and high-risk surgery, MTX, CsA, apremilast, abatacept, IL-17 inhibitors, IL-23 inhibitors, and ustekinumab are likely safe to continue; however, a case-by-case approach is advised. Acitretin can be continued for any surgery. There is insufficient evidence to make firm recommendations on tofacitinib, upadacitinib, and deucravacitinib.
