Ulcerative Colitis: Shifting Sands

Impact of Concomitant Thiopurine on the Efficacy and Safety of Filgotinib in Patients with Ulcerative Colitis: Post Hoc Analysis of the Phase 2b/3 SELECTION Study

BACKGROUND AND AIMS

SELECTION is the first study to assess the impact of concomitant thiopurine and other immunomodulator [IM] use on the efficacy and safety of a Janus kinase inhibitor, filgotinib, in patients with ulcerative colitis.

METHODS

Data from the phase 2b/3 SELECTION study were used for this post hoc analysis. Patients were randomised [2:2:1] to two induction studies [biologic-naive, biologic-experienced] to filgotinib 200 mg, 100 mg, or placebo. At Week 10, patients receiving filgotinib were re-randomised [2:1] to continue filgotinib or to switch to placebo until Week 58 [maintenance]. Outcomes were compared between subgroups with and without concomitant IM use.

RESULTS

At Week 10, similar proportions of patients in the +IM and -IM groups treated with filgotinib 200 mg achieved Mayo Clinic Score [MCS] response [biologic-naive: 65.8% vs 66.9%; biologic-experienced: 61.3% vs 50.5%] and clinical remission [biologic-naive: 26.0% vs 26.2%; biologic-experienced: 11.3% vs 11.5%]. At Week 58, similar proportion of patients in the +IM and -IM groups treated with filgotinib 200 mg achieved MCS response [biologic-naive: 74.2% vs 75.0%; biologic-experienced: 45.5% vs 61.4%] and clinical remission [biologic-naive: 51.6% vs 47.4%; biologic-experienced: 22.7% vs 24.3%]. The probability of protocol-specified disease worsening during the maintenance study in patients treated with filgotinib 200 mg did not differ between +IM and -IM groups [p = 0.6700]. No differences were observed in the incidences of adverse events between +IM and -IM groups in the induction/maintenance studies.

CONCLUSIONS

The efficacy and safety profiles of filgotinib treatment in SELECTION did not differ with or without concomitant IM use.

Clinical profiles and outcomes in patients with inflammatory bowel disease receiving standard and escalated doses of targeted therapies: findings from a global real-world study

OBJECTIVE

Although dosing regimens of targeted therapies (TT) for ulcerative colitis (UC) and Crohn's disease (CD) are guided by market authorizations and clinical guidelines, little is known about clinical guideline adherence or outcomes in patients receiving escalated doses of TT due to lack of response. This real-world study explored the prevalence of dose escalation and compared outcomes between patients receiving standard and escalated TT doses.

METHODS

Data were from the 2020-2021 Adelphi Disease Specific Programme for inflammatory bowel disease, a cross-sectional survey of gastroenterologists and their UC and CD patients across five European countries and the US. Physicians provided retrospective data collection of patient demographics, clinical characteristics, treatment history, and satisfaction; patients reported quality-of-life and work productivity. Patients were grouped by TT maintenance dose; standard and escalated dose groups were compared. Outcomes were adjusted for time on current TT and severity at current TT initiation using regression analyses.

RESULTS

Of 1,241 UC and 1,477 CD patients, 19.1% and 24.1%, respectively, received escalated TT doses. Despite escalation, a substantial proportion of patients had not achieved remission, had moderate or severe disease activity, or were flaring. Most physicians were not fully satisfied with treatment in the escalated dose group and were more likely to switch patients to another treatment regimen than patients on standard dose.

CONCLUSION

Dose escalation is not always an effective approach to resolve inadequate or loss of response in UC and CD, highlighting a need for more therapeutic options or alternative treatment strategies in patients unresponsive to TT.

Filgotinib for moderately to severely active ulcerative colitis

INTRODUCTION

Filgotinib is an oral Janus kinase type 1 (JAK1) selective inhibitor with demonstrated efficacy and safety in ulcerative colitis (UC). The aim of this review is to summarize the available evidence on pharmacological characteristics, efficacy, and safety of filgotinib in UC.

AREAS COVERED

Pubmed, Scopus, and Embase databases were searched for all relevant studies reporting the efficacy and safety of filgotinib in patients with moderate to severe UC. We particularly focused on the risk of zoster infection and venous thromboembolism compared to other JAK inhibitors.

EXPERT OPINION

Filgotinib has remarkable efficacy, safety, and tolerability profiles in the treatment of moderate-to-severe active UC. It can be used in both biologic-naïve and biologic-experienced patients. The rapid mechanism of action and its oral administration route make it a reliable therapeutic option.

INCIDENCE OF INFLAMMATORY BOWEL DISEASE: A SINGLE CENTRE RETROSPECTIVE STUDY

BACKGROUND

Inflammatory bowel disease (IBD) is a chronic inflammatory disorder affecting the gastrointestinal tract. The etiology of this alarming condition is multifactorial. A Recently increasing trend in IBD is noted in our country.

OBJECTIVE

The present study was designed with the main objective to assess the incidence and to identify the associated risk factors including demographic, geographical areas, and dietary patterns of IBD population of Northern of Karnataka viz. Hubli-Dharwad city.

METHODS

A retrospective investigation was conducted on a cohort of 226 patients with a working diagnosis of IBD and those who were admitted between 2015 to 2019 the department of gastroenterology, SDMCMS&H. The diagnosis of IBD was made based on clinical, radiological, endoscopic, and histopathologic findings. The patients were categorized into IBD and those who have symptoms suggestive of IBD but did not fit into the diagnostic criteria into, non-IBD groups. The data about of on demography, diet patterns, and laboratory parameters were recorded.

RESULTS

Among 226 patients enrolled in this study 2015-2019, IBD was confirmed in 54 Ulcerative colitis - 44 (19.46%), Crohn's disease - 10 (4.42%) patients with varying distribution of disease among different age groups and both genders, Ulcerative colitis (UC) [M: F: 28 (63.6%): 16 (36.4%)] and Crohn's disease (CD) [M: F: 07 (70.0%):03 (30.0%)]. Dietary pattern and other habitats had no significant contribution to illness and its symptoms. Urban (U) and Rural (R) divide was UC [U: R: 32 (72.7%): 12 (27.3%)], CD [U:R:07(70.0%):03(30.0%)] maintained.

CONCLUSION

Incidence of IBD was high with UC as compared to CD. The incidence of IBD among patients presenting with symptoms suggestive of IBD is 19.46% with UC being major as compared to CD (4.42%). Male predominant patterns of IBD incidences were noted. Year by year increasing trend in disease burden was observed. The Dietary pattern has no direct correlation with IBD disease prevalence and incidences.

Discovery of a Colon-Targeted Azo Prodrug of Tofacitinib through the Establishment of Colon-Specific Delivery Systems Constructed by 5-ASA-PABA-MAC and 5-ASA-PABA-Diamine for the Treatment of Ulcerative Colitis

To mitigate the systemic adverse effects of tofacitinib, 5-ASA-PABA-MAC and 5-ASA-PABA-diamine colon-specific delivery systems were constructed, and tofacitinib azo prodrugs 9 and 20a-20g were synthesized accordingly. The release studies suggested that these systems could effectively release tofacitinib in vitro, and the 5-ASA-PABA-diamine system could successfully realize the colon targeting of tofacitinib in vivo. Specifically, compound 20g displayed a 3.67-fold decrease of plasma AUC_{(tofacitinib, 0-∞)} and a 9.61-fold increase of colonic AUC_{(tofacitinib, 0-12h)}, compared with tofacitinib at a molar equivalent oral dose. Moreover, mouse models suggested that compound 20g (1.5 mg/kg) could achieve roughly the same efficacy against ulcerative colitis compared with tofacitinib (10 mg/kg) and did not impair natural killer cells. These results demonstrated the feasibility of compound 20g as an effective alternative to mitigate the systemic adverse effects of tofacitinib, and 5-ASA-PABA-MAC and 5-ASA-PABA-diamine systems were proven to be effective for colon-specific drug delivery.

Twenty-five years of biologicals in IBD: What´s all the hype about?

Twenty-five years ago the field was revolutionized by the introduction of infliximab as the first hybrid anti-TNF-antibody. Subsequently, other humanized anti-TNFs were developed and marketed, followed by antibodies to new targets including integrins (vedolizumab) and interleukin 12/23 (ustekinumab). All these so-called biologicals were shown in registrational trials to induce remission superior to placebo but consistently were effective in only a minority of patients. Even though in most trials only the responders were selected to continue on the respective medication for maintenance, many experienced a secondary loss of response and only a minority of usually <25% of the initial cohort achieved long-term (1 year) remission. In 'real life studies', the outcome was somewhat better, probably due to proper selection of patients and open, mostly retrospective study designs. A clear benefit of biologicals is apparent in otherwise treatment refractory patients, in extraintestinal manifestations and in Crohn´s disease (CD) with fistulizing complications. Biologicals achieve mucosal healing (MH) more often than corticosteroids or thiopurines, and MH is associated with improved prognosis. However, this does not justify escalating treatment until MH is reached since controlled trials proving this point of 'treat to target' are lacking both in ulcerative colitis and CD. Surgical rates have decreased with increasing use of biologicals, but disease progression has not been proven to improve. With the exception of opportunistic infections, serious adverse events are rare. In conclusion, biologicals have changed the scene considerably and expanded our armamentarium, but there is also a marketing hype fostering expectations without evidence.

Filgotinib as induction and maintenance therapy for ulcerative colitis (SELECTION): a phase 2b/3 double-blind, randomised, placebo-controlled trial

BACKGROUND

The global prevalence of ulcerative colitis is increasing, and induction and maintenance of remission is a crucial therapeutic goal. We assessed the efficacy and safety of filgotinib, a once-daily, oral Janus kinase 1 preferential inhibitor, for treatment of ulcerative colitis.

METHODS

This phase 2b/3, double-blind, randomised, placebo-controlled trial including two induction studies and one maintenance study was done in 341 study centres in 40 countries. Eligible patients were aged 18-75 years with moderately to severely active ulcerative colitis for at least 6 months before enrolment (induction study A: inadequate clinical response, loss of response to or intolerance to corticosteroids or immunosuppressants, naive to tumour necrosis factor [TNF] antagonists and vedolizumab [biologic-naive]; induction study B: inadequate clinical response, loss of response to or intolerance to any TNF antagonist or vedolizumab, no TNF antagonist or vedolizumab use within 8 weeks before screening [biologic-experienced]). Patients were randomly assigned 2:2:1 to receive oral filgotinib 200 mg, filgotinib 100 mg, or placebo once per day for 11 weeks. Patients who had either clinical remission or a Mayo Clinic Score response at week 10 in either induction study entered the maintenance study. Patients who received induction filgotinib were rerandomised 2:1 to continue their induction filgotinib regimen or to placebo. Patients who received induction placebo continued receiving placebo. The primary endpoint was clinical remission by Mayo endoscopic, rectal bleeding, and stool frequency subscores at weeks 10 and 58. For the induction studies, efficacy was assessed in all randomised patients who received at least one dose of study drug or placebo within that study. For the maintenance study, efficacy was assessed in all patients randomised to any filgotinib treatment group in the induction studies who received at least one dose of study drug or placebo in the maintenance study. Patients who received placebo throughout the induction and maintenance study were not included in the full analysis set for the maintenance study. Safety was assessed in all patients who received at least one dose of the study drug or placebo within each study. This trial is registered with ClinicalTrials.gov, NCT02914522.

FINDINGS

Between Nov 14, 2016, and March 31, 2020, we screened 2040 patients for eligibility. 659 patients enrolled in induction study A were randomly assigned to receive filgotinib 100 mg (n=277), filgotinib 200 mg (n=245), or placebo (n=137). 689 patients enrolled into induction study B were randomly assigned to receive filgotinib 100 mg (n=285), filgotinib 200 mg (n=262), or placebo (n=142). 34 patients in induction study A and 54 patients in induction study B discontinued the study drug before week 10. After efficacy assessment at week 10, 664 patients entered the maintenance study (391 from induction study A, 273 from induction study B). 93 patients continued to receive placebo. 270 patients who had received filgotinib 100 mg in the induction study were randomly assigned to receive filgotinib 100 mg (n=179) or placebo (n=91). 301 patients who had received filgotinib 200 mg in the induction study were randomly assigned to receive filgotinib 200 mg (n=202) or placebo (n=99). 263 patients discontinued treatment in the maintenance study. At week 10, a greater proportion of patients given filgotinib 200 mg had clinical remission than those given placebo (induction study A 26·1% vs 15·3%, difference 10·8%; 95% CI 2·1-19·5, p=0·0157; induction study B 11·5% vs 4·2%, 7·2%; 1·6-12·8, p=0·0103). At week 58, 37·2% of patients given filgotinib 200 mg had clinical remission versus 11·2% in the respective placebo group (difference 26·0%, 95% CI 16·0-35·9; p<0·0001). Clinical remission was not significantly different between filgotinib 100 mg and placebo at week 10, but was significant by week 58 (23·8% vs 13·5%, 10·4%; 0·0-20·7, p=0·0420). The incidence of serious adverse events and adverse events of interest was similar between treatment groups. In the induction studies, serious adverse events occurred in 28 (5·0%) of 562 patients given filgotinib 100 mg, 22 (4·3%) of 507 patients given filgotinib 200 mg, and 13 (4·7%) of 279 patients given placebo. In the maintenance study, serious adverse events were reported in eight (4·5%) of 179 patients given filgotinib 100 mg, seven (7·7%) of 91 patients in the respective placebo group, nine (4·5%) of 202 patients in the filgotinib 200 mg group, and no patients in the respective placebo group. No deaths were reported during either induction study. Two patients died during the maintenance study; neither was related to treatment.

INTERPRETATION

Filgotinib 200 mg was well tolerated, and efficacious in inducing and maintaining clinical remission compared with placebo in patients with moderately to severely active ulcerative colitis.

Single- and Multiple-Dose Pharmacokinetics and Pharmacodynamics of PN-943, a Gastrointestinal-Restricted Oral Peptide Antagonist of α4β7, in Healthy Volunteers

PN‐943 is an orally stable, gastrointestinal‐restricted peptide that binds specifically to α4ß7 integrin on leukocytes, blocking leukocyte trafficking to and activation in the gut, inhibiting colon inflammation and reducing signs and symptoms of active ulcerative colitis. Two pharmacokinetic/pharmacodynamic studies were conducted in healthy volunteers. Study 1 was a first‐in‐human study with 40 male subjects receiving PN‐943, 100 to 1400 mg or placebo, as single doses and 57 male subjects receiving PN‐943, 100 to 1000 mg or placebo, as multiple doses. Study 2 was a randomized, crossover study comparing multiple doses of 450‐mg PN‐943 twice daily as a liquid solution and as an immediate‐release tablet in 10 subjects. No subjects discontinued due to treatment‐emergent adverse events. Consistent with the gastrointestinal‐restricted nature of the peptide, systemic exposure was minimal; there was an approximate dose‐proportional increase in area under the plasma concentration–time curve. There was minimal accumulation with once‐daily dosing and an absence of time‐dependent changes in pharmacokinetics. Administration of PN‐943 after a high‐fat meal reduced peak plasma concentration and area under the plasma concentration–time curve. There was minimal (<0.1%) urinary excretion of intact drug, and there was a dose‐related increase in fecal excretion of intact PN‐943. Dose‐dependent increases in blood receptor occupancy and reduction in blood receptor expression were observed, supporting target engagement. Twice‐daily dosing resulted in sustained receptor occupancy with low plasma fluctuations (143%). PN‐943 was generally well tolerated following single and multiple oral doses with low systemic exposure. Twice‐daily dosing resulted in sustained pharmacokinetics and pharmacodynamics, supporting further investigation in efficacy studies.

Self-medication with oral corticosteroids reported by patients with ulcerative colitis: characteristics, reasons and patients' behaviors

BACKGROUND

Few studies have examined self-medication with corticosteroids among patients with ulcerative colitis (UC).

AIMS

To assess the frequency of self-medication with oral corticosteroids in UC patients, and associated factors and reasons.

METHODS

An anonymous, voluntary, web-based survey was administered to adults with UC recruited via a Spanish patient association (ACCU) and hospital gastroenterology departments. Information was provided by patients; no clinical data were collected. Descriptive statistics and comparisons of frequencies are displayed.

RESULTS

Among 546 respondents (mean age 39.9 years, median duration of UC since diagnosis 7 years,) 36 (6.6%) reported self-medication with oral corticosteroids during the past year (once: 23 patients; 2-3 times: 10 patients; >3 times: 3 patients). Self-medication was more common among patients managed in general gastroenterology vs. inflammatory bowel disease clinics [23 (9.0%) vs. 11 (2.9%), P = 0.019], patients with no regular follow-up [4 (22.2%) vs. 32 (6.1%), P = 0.026] and patients with more flares (P < 0.001). Patients who stored steroids from previous flares (17.9% vs. 6.0%, P < 0.001) or who lived with a partner taking steroids (9.3% vs. 1.1%, P = 0.038) were more likely to self-medicate than other patients. Common reasons for self-medicating included the need for quick symptom relief (55.6%), fear of worsening (47.2%) and difficulty in getting an appointment (25.0%). Only seven patients (19.4%) informed their physician when they started self-medicating and only four (11.1%) declared they would not start corticosteroids again.

CONCLUSION

Self-medication with oral corticosteroids is not a common practice among patients with UC in Spain, but several areas of improvement exist.

Efficacy and safety of ustekinumab in East Asian patients with moderately to severely active ulcerative colitis: a subpopulation analysis of global phase 3 induction and maintenance studies (UNIFI)

Background/Aims

We aimed to evaluate the efficacy and safety of ustekinumab (UST) in the East-Asian population with moderate to severely active ulcerative colitis (UC).

Methods

This sub-analysis was conducted on data from East-Asian patients included in the UNIFI program (NCT02407236). UNIFI consisted of two double-blind, placebo-controlled trials: an 8-week induction study and a 44-week randomized withdrawal maintenance study.

Results

Of 133 East-Asian patients (Japanese: 107, Korean: 26) who underwent randomization, 131 completed induction study and 111 entered maintenance study. In the maintenance study, 78 patients were randomized. Patients who received UST 130 mg and UST 6 mg/kg showed numerically higher clinical remission at week 8 in the induction study (5/44 [11.4%] and 5/45 [11.1%], respectively) compared with those who received placebo (0/44, 0%). The proportion of patients achieved clinical remission at week 44 was numerically higher in the UST 90 mg q12w group (10/21, 47.6%), but similar in the UST 90 mg q8w group (5/26, 19.2%) compared to placebo (7/31, 22.6%). Serious adverse events were reported in 1 patient in UST 130 mg group, but no patient in UST 6 mg/kg group through week 8 in the induction study, and 1 patient in UST 90 mg q12w group and 5 patients in the UST 90 mg q8w group in the maintenance study. No deaths were reported in East-Asian patients throughout the study.

Conclusions

UST induction and maintenance treatments were effective in East-Asian patients with moderate to severe UC; the efficacy and safety profiles were consistent with the overall population.

Cobitolimod for moderate-to-severe, left-sided ulcerative colitis (CONDUCT): a phase 2b randomised, double-blind, placebo-controlled, dose-ranging induction trial

BACKGROUND

Cobitolimod is a topically administered, DNA-based oligonucleotide that activates Toll-like receptor 9 (TLR9), and previous research has shown clinical efficacy in patients with moderate-to-severe ulcerative colitis. Here we assessed the efficacy and safety of different dose regimens of cobitolimod for induction therapy in patients with moderate-to-severe, left-sided ulcerative colitis.

METHODS

CONDUCT was a randomised, double-blind, five-arm, placebo-controlled, dose-ranging phase 2b study that recruited patients with moderate-to-severe, left-sided ulcerative colitis, with inadequate response to conventional or biological therapies, from 91 hospitals or outpatient clinics in 12 European countries. Eligible patients had a Mayo score of 6-12 with a centrally read endoscopic subscore (modified to exclude friability from grade 1) of 2 or higher and no individual subscore of less than 1, and confirmation of left-sided disease. Patients were randomised (1:1:1:1:1; block size of ten) via a computer-generated schedule and centralised interactive voice and web response system to receive rectal enemas of cobitolimod at 31 mg, 125 mg, or 250 mg at weeks 0 and 3 (2 × 31 mg, 2 × 125 mg, and 2 × 250 mg groups), cobitolimod at 125 mg at weeks 0, 1, 2, and 3 (4 × 125 mg group), or placebo. Randomisation was stratified by current glucocorticosteroid and previous tumour necrosis factor inhibitor treatment. Patients and all study personnel were masked to treatment allocation. The primary endpoint was the proportion of patients achieving clinical remission (Mayo subscores for rectal bleeding of 0, for stool frequency of 0 or 1 [with ≥1-point decrease from baseline], and for endoscopy of 0 or 1 [excluding friability]) at week 6. The primary analysis (based on intention to treat) and safety analysis were done in all randomly assigned patients who received at least one dose of active study drug or placebo. In this exploratory study, statistical tests were one-sided; p values of less than 0·10 were regarded as statistically significant, with no adjustment for multiplicity. This study is registered with ClinicalTrials.gov, NCT03178669, and is completed; the results here represent the final analysis.

FINDINGS

213 patients were randomly assigned between June 30, 2017, and June 26, 2019. Of these, 211 patients received study treatment: 40 in the cobitolimod 2 × 31 mg group, 43 in the 2 × 125 mg group, 42 in the 4 × 125 mg group, 42 in the 2 × 250 mg group, and 44 in the placebo group. A greater proportion of patients were in clinical remission at week 6 in the cobitolimod 2 × 250 mg group than in the placebo group (nine [21%] of 42 patients vs three [7%] of 44; odds ratio [OR] 3·8 [80% CI 1·5-9·5]; one-sided p=0·025). We identified no significant difference in the proportion of patients with clinical remission in the cobitolimod 2 × 31 mg group (five [13%] of 40 patients; OR 2·0 [80% CI 0·7-5·5], p=0·18), 2 × 125 mg group (two [5%] of 43; 0·7 [0·2-2·2], p=0·66), or 4 × 125 mg (four [10%] of 42; 1·4 [0·5-3·9], p=0·33) compared with the placebo group. Treatment-emergent adverse events occurred in 21 (48%) patients in the placebo group, ten (25%) patients in the cobitolimod 2 × 31 mg group, 17 (40%) patients in the 2 × 125 mg group, 15 (36%) patients in the 4 × 125 mg group, and 18 (43%) patients in the 2 × 250 mg group. Severe adverse events occurred in eight (4%) of 211 patients (worsening of ulcerative colitis [seven patients] and abdominal hernia and wound dehiscence [one patient]). Ten patients (two [5%] in the placebo group, two [5%] in the cobitolimod 2 × 31 mg group, two [5%] in the 4 × 125 mg, and four [10%] in the 2 × 250 mg group) had a total of 13 serious adverse events; these were worsening of ulcerative colitis (eight events) and pruritus, rash, abdominal hernia, fascia dehiscence, and deep vein thrombosis (one event each). One patient in the placebo group died from total organ failure after receiving a colectomy for a serious adverse event of disease worsening.

INTERPRETATION

Two topical administrations of cobitolimod 250 mg were well tolerated and more effective than placebo in inducing clinical remission 6 weeks after the start of treatment. TLR9 activation is a promising novel therapeutic target in ulcerative colitis and warrants further testing, with phase 3 trials of cobitolimod planned.

Design, synthesis and evaluation of a baicalin and berberine hybrid compound as therapeutic agent for ulcerative colitis

Structural modification of active natural compoundswhichwereoriginated fromTraditional Chinese Medicine (TCM) have showedgreat advantagesin thedevelopmentof new drugs. In TCM, "Huangqin-Huanglian" is a classic "medicine couple"thathas been used to treat intestinal diseases for thousands ofyears, while baicalinand berberine are the major active compoundsof Huangqin and Huanglianrespectively. Based onthis"medicine couple",wedesignedand synthesizeda newbaicalin and berberine hybrid compound (BBH).Its molecular structure wasconfirmedby spectroscopy.The antibacterial activity of BBH was detected in vitro.Results indicatedthat the new hybrid compound exhibited the best antibacterial activity forproteobacteria as compared with its original synthetic materials (baicalin andberberine). In vivo, the effect of BBHon ulcerative colitiswas alsoinvestigated.BBH treatment significantly ameliorated the disease symptoms andpreventedthe colon damage of ulcerative colitis. Furthermore, BBH showed asignificant anti-inflammatory effect through regulating activities of SOD, MPOandexpressions of pro-inflammatory cytokines (TNF-α, IL-1β and IL-6) in colontissue. Data also suggested that BBH was more superior than baicalin and berberine inameliorating colonic damage. This indicated that the new hybrid compound BBHshowed enhanced efficacy in treating ulcerative colitis.

Treatment De-Escalation in Patients With Inflammatory Bowel Disease

Inflammatory bowel disease follows a relapsing and remitting course that can be augmented with the use of various pharmacologic therapies. Treatments used to induce or maintain remission may not be required indefinitely. The associated side-effect profile, adverse events, and costs are additional motivators for providers to treat patients with the lowest dose of effective medications. De-escalation of therapy, whether dose reduction or drug discontinuation, must be carefully considered on an individual patient basis. The steps for de-escalation include confirmation of deep remission, development of a maintenance strategy, discussion of the rescue threshold and treatment options in the event of relapse, and appropriate discussion with the patient of this plan.
