Approval: 1999', 2015). At more than 300 mg/m 2 /d, 55% (21 of 38) of patients One of the most promising approaches to delay, prevent or reverse disability progression in multiple sclerosis (MS) is to enhance endogenous remyelination and limit axonal degeneration. They stratify MS patients into groups A trial of cancer drug bexarotene has proven that human myelin can be repaired. Methods 24-month-old 3xTg-AD mice were treated with bexarotene (100 mg/kg/day for A drug–drug interaction was seen in this trial with bexarotene co-administration leading to a significant reduction in the AUC of atorvastatin. Rodriguez tested a monoclonal antibody—one of three his lab identified that bind to the surface of oligodendrocytes and trigger remyelination in experimental models of MS—for The MS-SPI study showed a small statistically significant effect in 12. In: Cancer chemotherapy and pharmacology, Vol. The safety profile from the one post-approval trial with 59 subjects was generally comparable to that of the pivotal trials with the exception of serious adverse events hypertriglyceridemia, neutropenia and bone marrow failure which were observed more frequently in the bexarotene 300 mg/m 2 /day group than in the bexarotene 150 mg/m 2 /day group. 2 ± 2. To our knowledge, this clinical trial is also the first to Bexarotene targets the retinoid X receptor on oligodendrocytes and stimulates myelin production. ly/2S28I20 11 Feb 2016. Single MS lesion magnetisation transfer ratio (MTR), an MRI parameter of tissue integrity and a putative biomarker of myelination ( Altmann et al. gov and the ISRCTN Registry using the same date restrictions and the search term “remyelination”. In the intention-to-treat population, bexarotene did not have a significant treatment effect on P100 latency for all eyes compared with placebo (table 4; figure 3 A); however, in the per-protocol analysis, bexarotene reduced P100 latency compared with placebo (adjusted bexarotene–placebo difference –4·02 ms, 95% CI –7·27 to –0·76; p=0·015). 2012, p. The validated assay method for bexarotene concentrations in heparinized human plasma was previously reported [22]. One) trial of bexarotene1 was the third phase 2 trial – after the ReBUILD study of clemastine,2 and the RENEW trial of opicinumab 3 – to show a remyelinating effect through a reduction in the latency of the visual evoked potential (VEP). terms “multiple sclerosis” OR “MS” AND “remyelination”. The trial is for the re-purposing of the drug bexarotene, which is being tested for its ability to boost myelin repair. Results Bexarotene Promotes the Induction of Human Tregs it is unlikely that bexarotene will progress further into clinical There are indications that bexarotene may induce CYP3A4. has just published some very important results from a phase 2 trial involving 50 people with relapsing remitting MS, all already taking a disease modifying treatment. The MS Society in the U. New research presented at the MSVirtual2020 conference has shown that bexarotene, a drug developed to Bexarotene, a retinoid X receptor (RXR) agonist, is approved by FDA to treat cutaneous T-cell lymphoma. For patients bexarotene is user-friendly, convenient and easy to administer. We also searched, without any language restrictions, the clinical trials databases ClinicalTrials. Although these results are disappointing, we remain dedicated to funding research that can Purpose Bexarotene (Targretin® capsules) is a retinoid-X-receptor agonist and an inducer of CYP3A4-mediated metabolism. Objectives We aimed to assess disease response to low-dose bexarotene and PUVA in maintenance in refractory and/or resistant patients with early and advanced stage MF/SS. However, it has also demonstrated promising therapeutic potential for neurological diseases such as stroke, traumatic brain injury, Parkinson’s disease, and particularly Alzheimer's disease(AD). Very disappointingly, top line results announced in 2024 showed simvastatin did not have an effect on The effect of bexarotene on atorvastatin pharmacokinetics: results from a phase I trial of bexarotene plus chemotherapy in patients with advanced non-small cell lung cancer (LC/MS/MS).

June 2001; Journal of Clinical Oncology 19(9):2456-71; In this clinical trial, a novel regimen of low dose bexarotene (Targretin, 75 mg/day) will be added for 6 weeks to the standard treatment of 15 schizophrenia patients on stable antipsychotic treatment. In contrast, IRX4204 selectively activates the retinoid Introduction Bexarotene, a retinoid X receptor agonist, improves cognition in murine models of Alzheimer’s disease (AD). In September 2013, alemtuzumab received its European license and in 2014 it was approved by the FDA and by NICE. ; Lopez-Anaya, Arturo et al. Results are . It can be used as monotherapy or in combination with other therapies. New research presented at the MSVirtual2020 conference has In this series of blogs and vlogs, Hellie, a person with MS chronicles her journey taking part in a clinical trial. Now, the first To stop MS we need to find treatments that repair the damage to the protective myelin coating around nerves. Bexarotene is a Food and Drug Administration approved selective RXR (retinoid X receptor) agonist for clinical use in patients with cutaneous T-cell lymphoma. Bexarotene. However, the MS-ON study returned a negative result when change in visual acuity was employed as the primary end point . However, our results support the bexarotene (a retinoid X receptor agonist with activity against the α, β, and γ isoforms) in people with relapsing-remitting multiple sclerosis. 6% of treated participants when using an improvement of either the EDSS or timed 25-foot walk as its outcome . Bexarotene Is Effective and Safe for Treatment of Refractory Advanced-Stage Cutaneous T-Cell Lymphoma: Multinational Phase II-III Trial Results. ; Takimoto, Chris H. This is a breakthrough that scientists say is critical to their goal of stopping MS. This Bexarotene is used to treat skin cancer and was tested as a treatment for MS. Participants will be assessed at baseline and after 2, Background: Bexarotene (Targretin oral capsules), the first RXR-selective retinoid “rexinoid” approved for all stages of cutaneous T-cell lymphoma (CTCL), had a response rate (RR) of 45% at the optimal dose of 300 mg/m 2 per day in 2 multicenter trials. that number is closer to one million, so the MS Society is not relying on just the bexarotene trials, but is also launching a Phase 2 Published results from a phase 2 clinical trial of oral bexarotene in people with MS reveal that there were some signs that the drug could help restore the myelin coating on nerve fibers damaged by MS, but the key MRI outcome measured in the trial was not met and people taking the drug experienced serious side effects. 4 Unfortunately, 300 mg/m 2 bexarotene was poorly tolerated, but the Overall, these data suggest that bexarotene has a remyelinating effect in humans, sustained years after the treatment period has concluded. 4 Unfortunately, 300 mg/m 2 bexarotene was poorly tolerated, but the Clinical response to bexarotene (Targretin capsules). Our results show that bexarotene was equally effective as monotherapy or The optimal use of bexarotene in cutaneous T-cell lymphoma Br J Dermatol 2007;157:433-40. Bexarotene (and 13 C 4-labeled bexarotene) was extracted from the sample via liquid–liquid extraction [31]. The trial actually goes back to over a decade ago when one of the laboratories in Cambridge noted that if you target a particular part of the cell, the RXR-gamma, it can enhance remyelination in animals.

Eligible participants were aged 18–50 years and had been receiving dimethyl fumarate for at least 6 months. , who reported no significant difference in the response rate or response duration in a randomized clinical trial of bexarotene and PUVA combination therapy and bexarotene monotherapy in European early-stage MF patients; the best overall response rate was 71% for PUVA monotherapy and 77% for The Cambridge Centre for Myelin Repair One (CCMR One) trial of bexarotene 1 was the third phase 2 trial – after the ReBUILD study of clemastine, 2 and the RENEW trial of opicinumab 3 – to show a remyelinating effect through a reduction in the latency of the visual evoked potential (VEP). The cancer medication bexarotene, aka Targretin®, made headlines with a report that it quickly lowered brain Aβ, reduced plaque load, and improved behavioral deficits in mouse models of Alzheimer’s disease. Clinical Trials Accepting Patients. Methods: This randomised, double New research presented at the MSVirtual2020 conferencehas shown that bexarotene, a drug developed to treat cancer, is able to repair myelin in people with relapsing MS. Macnair and Calini et al. The result showed that beta amyloid plaques in the brain were reduced. 69, No. Results of the 2015 clinical trial showed that rHIgM22 reported no adverse effects or discontinuations. Ellen Mowry, an associate professor of neurology at Johns Hopkins University, is the principal investigator on a In vitro, bexarotene inhibits the proliferation of non-M3 AML cell lines and induces differentiation of leukemic blasts. 4 Unfortunately, 300mg/m2 bexarotene was poorly tolerated, but the lessons learned The concentrations of bexarotene in mice brain tissue were 18. 37 After an acute inflammatory episode remyelination continues for at least a year, 38 so sensitivity to treatment effects may be meaningfully enhanced by extending Bexarotene and AD. , 2014 ; Schmierer et al. CCMR-One was a double-blind, placebo-controlled, phase 2a trial that recruited patients with relapsing-remitting MS, aged 18-50 years old, who had been receiving dimethyl fumarate for at least 6 months. Repairing the damage to nerves caused by MS is possible, according to new research. A trial of cancer drug bexarotene has proven that human myelin can be repaired. Our previous phase I study in In support of analyses of participants with delayed P100 latency at baseline, without a recent history of acute ON, the CCMR One trial similarly reported a statistically significant improvement in ff-VEP P100 latency among eyes with baseline values >118 ms. The distribution of bexarotene in brain tissue is shown in Fig. The results from our Phase 2a clinical trial have shown that bexarotene is capable of regenerating lost myelin – the protective coating that surrounds nerve fibres, which is damaged in MS. It is not a substitute for medical advice. A study of the cancer drug bexarotene in Cambridge and Edinburgh showed that it led to the regrowth of myelin in people with The Cambridge Centre for Myelin Repair One (CCMR One) trial of bexarotene 1 was the third phase 2 trial – after the ReBUILD study of clemastine, 2 and the RENEW trial of opicinumab 3 – to show a remyelinating effect through a reduction in the latency of the visual evoked potential (VEP). 0, 330 ± 75, 143 ± 50 and 12. In a phase 1 clinical trial of 72 patients with MS, Dr. It found that while bexarotene did not impact the primary outcome of lesion magnetization transfer ratio, Although a phase 2 clinical trial in MS suggested that Bexarotene improved remyelination, adverse side effects halted further development (Brown et al. Find Clinical Trials for Bexarotene - Check for trials from NCI's list of cancer clinical trials now accepting patients. Bexarotene concentration was measured in plasma and CSF samples using gas chromatography and/or MS. I was diagnosed with MS in 2016 and I’ve been taking Tecfidera for just over a year. The likely mechanism for this interaction is through induction of CYP3A4 by bexarotene given the role of this enzyme in the metabolism of atorvastatin. Prof Alasdair Coles explains the results, and how repairing myelin can stop MS progression. For full details of the CCMR-One protocol please refer to the published trial manuscript (Ref). / Wakelee, Heather A. This study evaluated the effects of bexarotene on pathological and electrophysiological changes in very old triple transgenic AD mice (3xTg-AD mice). The effect of bexarotene on atorvastatin pharmacokinetics: Results from a phase i trial of bexarotene plus chemotherapy in patients with advanced non-small cell lung cancer. With hypertriglyceridemia reported at 79%, bexarotene is often administered with lipid-lowering The TREAT-MS Clinical Trial for Multiple Sclerosis (MS) Patients An Exciting Interview from the PCORI Annual Meeting. , 2021). 2, 02. , 2008 ), was the primary efficacy MS-STAT2 completed recruitment in late 2021, becoming the largest ever academic-led trial for progressive MS. This phase 2 trial will test if a drug called bexarotene can help the brain regenerate myelin in people with MS. With hypertriglyceridemia reported at 79%, bexarotene is often administered with lipid-lowering Whittaker S, Ortiz P, Dummer R, Ranki A, Hasan B, Meulemans B, Gellrich S, et al. This clinically promising remyelinating agent activates multiple nuclear hormone receptor subtypes implicated in myelin repair. This result revealed that bexarotene was able to across the blood brain barrier. At more than 300 mg/m 2 /d, 55% (21 of 38) of patients responded, including 13% (five of 38) clinical complete. S. 18 This trial assessed the effect of bexarotene —an agonist of the retinoic acid RESULTS: Clinical trials show a comparable efficacy of NPLD and PLD in non-Hodgkin lymphoma. Bexarotene is the first retinoid approved by the & Pimpinelli, 2013), bexarotene, is in preparation for an MS trial. Knowledge of this interaction is important for optimizing lipid Similarly, it is worth noting that this trial was 6 months long, and we do not know if bexarotene had had sufficient time for its maximal effect to be observed (VEPs continued to improve 28 months after stopping bexarotene). 3,4 The combination of these two outcomes offers an appealing phase 2 screening framework I’m currently taking part in a clinical trial for bexarotene, a drug which may promote remyelination in people with MS. This phase I trial evaluated the pharmacokinetic (PK) and drug–drug interactions of bexarotene with chemotherapy and a lipid-lowering agent (atorvastatin or fenofibrate). One recent example is the skin cancer drug, bexarotene. In AD, bexarotene inhibits the production and Myelin Sheath. 25 subjects were given bexarotene once daily for 6 months, whilst the other 25 were given a In the intention-to-treat population, bexarotene did not have a significant treatment effect on P100 latency for all eyes compared with placebo (table 4; figure 3A); however, in the per-protocol analysis, bexarotene reduced P100 Around 100,000 people in the UK live with MS, and in the U. We have Our study results are consistent with the findings of Whittaker et al. Repairing myelin is vital to stop MS. Several clinical trials using a potentially remyelinating drug to The Cambridge Centre for Myelin Repair One (CCMR One) trial of bexarotene 1 was the third phase 2 trial – after the ReBUILD study of clemastine, 2 and the RENEW trial of opicinumab 3 – to show a remyelinating effect through a reduction in the latency of the visual evoked potential (VEP). phase I trial of bexarotene in combination with docetaxel in patients . However, bexarotene will We do not recommend bexarotene as a treatment of multiple sclerosis because of its poor tolerability and negative primary efficacy outcome. For the 300 mg/m 2 /d initial dose group, the rate of relapse after response was The clinical trial results with bexarotene are reviewed, especially in comparison with interferon-alpha, which is the other commonly used noncytotoxic systemic therapy for CTCL. I attend the Anne Rowling Clinic in Edinburgh and had read about the bexarotene trial on their website. In laboratory studies, bexarotene showed the potential to repair myelin. Results Bexarotene Promotes the Induction of Human Tregs it is unlikely that bexarotene will progress further into clinical development as a We know this will be disappointing news for participants, the trial team and people living with MS. Briefly, a known amount of internal standard (13 C 4-labeled bexarotene) was added to each plasma and CSF sample. Bexarotene is an RXR agonist which was shown to restore the phagocytic capacity of blood monocyte-derived macrophages derived from evaluating the safety and tolerability of single rHIgM22 in patients with MS. , 2021; Cochrane Library, 2019). Whilst results showed bexarotene did show some effects on boosting myelin repair, unfortunately side effects experienced by One of the major talking points from the MS Virtual 2020 conference was the results from a recent clinical trial testing a potential remyelination therapy, c Even though bexarotene was not safe and did not improve function, this trial identifies grey matter remyelination as a useful outcome measure, in addition to electrophysiology (visual evoked potentials), which was studied in clinical trials testing the efficacy of clemastine and opicinumab. Our focus now is on remyelinating therapies. Now, a new trial of the diabetes drug metformin will build on this work. rHIgM22 was measurable in the The results from the MS Society‘s Phase 2a clinical trial have shown that bexarotene is capable of regenerating lost myelin – the protective coating that surrounds nerve fibres, which is damaged in MS. An Bexarotene, a pan retinoid X receptor (RXR) agonist licensed for use in humans as a treatment of cutaneous T-cell lymphoma, has recently been shown to promote remyelination in multiple sclerosis (MS). This trial was run in parallel with phase III trials of the We started using it to treat multiple sclerosis in1991. 4 Unfortunately, 300 mg/m 2 bexarotene was poorly tolerated, but the lessons learned These results were disappointing, In a phase II clinical trial in 50 participants with relapsing MS and evidence of long term damage to the optic nerve, including bexarotene, biotin and cell-based therapies, which have been completed or are underway. However, BXT produces unacceptable hyperlipidemia.
