Delving into the Latest Updates on Bardoxolone Methyl with Synapse

This multi-center, randomized, double-blind, placebo-controlled, Phase 2 trial will study the safety, tolerability, and efficacy of bardoxolone methyl in qualified patients with CKD due to multiple etiologies at risk of rapid disease progression. Approximately 70 patients will be enrolled and randomized 1:1 to either bardoxolone methyl or placebo. Patients with CKD secondary to varying etiologies will be enrolled from age 18-70 years with eGFR ≥ 20 to < 60 mL/min/1.73 m2, and other risk factors for rapid progression of kidney disease.
The maximum target dose will be determined by baseline proteinuria status. Patients with baseline urine albumin to creatinine ratio (UACR) ≤ 300 mg/g will be titrated to a maximum dose of 20 mg, and patients with baseline UACR > 300 mg/g will be titrated to a maximum dose of 30 mg. Qualified patients will be randomized 1:1 to receive either bardoxolone methyl or placebo once daily (preferably in the morning) throughout a 12-week dosing period.
Patients in the study will follow the same visit and assessment schedule. Patients will be assessed during treatment at Day 1, Weeks 1, 2, 4, 6, 8, and 12 and by telephone contact on Days 3, 10, 21, 31, 35, and 45. Date of last dose and the end-of-treatment assessments mark the end of the treatment period. Patients will not receive study drug during a 5-week off-treatment period between Weeks 12 and 17. The off-treatment (OT) period includes 5 visits requiring various assessments to characterize eGFR from the time of study drug discontinuation through Day 35 off-treatment.

CDDO-Me triggers ROS-dependent ferroptosis and apoptosis in cervical cancer via targeting PI3K/Nrf2 pathway

Article

Author: Feng, Xinyue ; Li, Wenxuan ; Wang, Mengying ; Han, Anna ; Chen, Liyan ; Du, Pan

CONTEXT:

Cervical cancer (CC) ranks as one of the most common types of malignant tumors affecting women. CDDO-Me is derived from oleanolic acid, a pentacyclic triterpenoid obtained by chemical structural modification, which has been shown anti-tumor effects.

RESULTS:

CC cell proliferation was decreased by CDDO-Me both in vitro and in vivo. Mechanistically, CDDO-Me led to a reduction of intracellular mitochondrial volume and crista, or an increase of membrane density. The levels of ROS, Fe²⁺, MDA were increased while GSH was decreased. Meanwhile, the levels of protein expression of GPX4, Nrf2, NQO1 and FTH1 were observably inhibited by CDDO-Me. Specifically, ferroptosis triggered by CDDO-Me was reverted by DFO. It has been demonstrated that CDDO-Me-induced apoptosis and ferroptosis in CC cells is contingent upon the PI3K/AKT-mediated Nrf2/NQO1 pathway.

CONCLUSIONS:

CDDO-Me induces CC cell lines apoptosis and ferroptosis through the PI3K/Nrf2 signaling pathway, for exerting anti-proliferation effects.

Advances in KEAP1-based PROTACs as emerging therapeutic modalities: Structural basis and progress

Review

Author: Li, Hua ; Chen, Jing ; Chen, Lixia ; Zhu, Rui ; Feng, Disheng

Kelch-like ECH-associated protein 1 (KEAP1) functions as a substrate adaptor for the Cullin 3-RING E3 ligase complex, mediating the ubiquitination and subsequent proteasomal degradation of nuclear factor erythroid 2-related factor 2 (NRF2). This regulatory mechanism maintains cellular redox homeostasis by preventing NRF2 overactivation. Proteolysis-targeting chimeras (PROTACs) have emerged as a novel therapeutic strategy that harnesses the ubiquitin-proteasome system for targeted protein degradation. Recent advancements have expanded the repertoire of E3 ligases exploitable for PROTAC design, with KEAP1 identified as a promising candidate. This review provides a comprehensive overview of the structural and functional characteristics of KEAP1, detailing its interactions with NRF2 and Cullin 3. The development of KEAP1- recruiting PROTACs utilizing ligands derived from different classes of known KEAP1 inhibitors-including short peptides, covalent small molecules (e.g., CDDO derivatives), and non-covalent inhibitors (e.g., KI696)-is discussed, highlighting the potential to diversify the available E3 ligase recruiters. Recent progress in developing KEAP1-based PROTACs targeting BRD4, CDK9, FAK, Tau and KEAP1 itself is highlighted, with particular emphasis on ligand optimization strategies employed to enhance degradation efficacy and specificity. Elucidating the structural basis of KEAP1 interactions provides crucial insights for advancing PROTAC applications. However, current challenges in KEAP1-based targeted protein degradation warrant further investigation to fully realize its therapeutic potential. Future research should focus on optimizing KEAP1 ligand properties and exploring novel protein targets amenable to degradation via KEAP1 recruitment to further advance this innovative therapeutic modality.

Basal activation of astrocytic Nrf2 in neuronal culture media: Challenges and implications for neuron-astrocyte modelling

Article

Author: Elsharkasi, Mohamed Moftah Omer ; Kerr, Fiona ; Wells, Geoffrey ; Villani, Beatrice

As a gatekeeper of antioxidant and anti-inflammatory cell protection, the transcription factor Nrf2 is a promising therapeutic target for several neurodegenerative diseases, leading to the development of Nrf2 activators targeting Keap1-dependent and independent regulatory mechanisms. Astrocytes play a crucial role in regulating neuronal physiology in health and disease, including Nrf2 neuroprotective responses. As neurons require specific conditions for their differentiation and maintenance, most 2D and 3D co-culture systems use medias that are compatible with neuronal differentiation and function, but also ensure astrocyte survival. Few studies, however, assess the molecular adaptations of astrocytes to changes from astrocyte maintenance medias alone, and their subsequent effects on neurons which may represent technical rather than physiological responses. Our findings show that while Nrf2 can be effectively activated by the Keap1-Nrf2 protein-protein interaction disruptor 18e, and classical Nrf2 activators dimethylfumarate and CDDO-Me, in human primary cortical astrocyte monocultures, their efficacy is lost in LUHMES neuron-astrocyte co-cultures. Further investigation revealed that the Advanced DMEM/F12-based LUHMES differentiation media maximally induced basal Nrf2 activity in astrocytes alone, compared to astrocyte maintenance media, thus preventing pharmacological activation. Although Neurobasal slightly activated basal Nrf2, this was not significant and did not prevent further activation by dimethylfumarate, suggesting that this media has less impact on astrocytic Nrf2 activity relative to Advanced DMEM/F12. As Nrf2 is a key regulator of oxidative damage and neuroinflammation, modelling these common features of neurodegenerative diseases may be confounded by environments that maximally activate basal Nrf2. Our findings thus suggest caution in media selection for neuron-astrocyte co-culture in disease modelling and therapeutic Nrf2 activator discovery, and suggest use of Neurobasal over Advanced DMEM/F12 medias for this purpose.

What are Nrf2 inhibitors and how do you quickly get the latest development progress?

Nrf2, or nuclear factor erythroid 2-related factor 2, is a transcription factor that plays a crucial role in the human body's defense against oxidative stress and inflammation. It regulates the expression of various antioxidant and detoxification genes, promoting cellular protection and maintaining redox homeostasis. Nrf2 activation is essential for combating harmful free radicals and reactive oxygen species, which can lead to various diseases, including cancer, neurodegenerative disorders, and cardiovascular conditions. Understanding and harnessing the potential of Nrf2 signaling pathways have become a significant focus in pharmaceutical research, aiming to develop novel therapeutic interventions for oxidative stress-related diseases. Due to the biological characteristics of tumors, multidrug resistance (MDR) is a major cause of chemotherapy failure. Studies have shown that high expression of Nrf2 is found in different types of cancer cells (bladder cancer, lung cancer, pancreatic cancer, liver cancer, and head and neck cancer). Nrf2 can activate the transcription of more than 500 genes in the human genome, most of which have cell protective functions, enhancing the detoxification and excretion of harmful substances and toxic metals, thereby leading to tumor resistance to chemotherapy drugs. Therefore, the development of Nrf2 inhibitors is considered an important strategy to overcome chemotherapy drug resistance. The use of Nrf2 inhibitors as sensitizers in combination with anticancer drugs will reverse tumor resistance and significantly improve the efficacy of chemotherapy drugs. The analysis of the target Nrf2 in the pharmaceutical industry reveals a competitive landscape with companies like Biogen, Inc., Reata Pharmaceuticals, Inc., and Teva Pharmaceutical Industries Ltd. leading the way in R&D progress. Multiple drugs targeting Nrf2 have been approved for indications such as Multiple Sclerosis and Friedreich Ataxia. Small molecule drugs are progressing rapidly, with biosimilars indicating intense competition. The United States is at the forefront of development, followed by the European Union, China, and other countries. The future development of target Nrf2 holds promise for the treatment of various indications and requires continued research and investment in innovative drug development. How do they work?Nrf2 inhibitors are a class of compounds or drugs that specifically target and inhibit the activity of the nuclear factor erythroid 2-related factor 2 (Nrf2). Nrf2 is a transcription factor that plays a crucial role in regulating the expression of genes involved in antioxidant response and cellular defense against oxidative stress. From a biomedical perspective, Nrf2 inhibitors are of interest because they have the potential to modulate the Nrf2 pathway and alter the cellular response to oxidative stress. By inhibiting Nrf2, these compounds can prevent the activation of antioxidant genes and disrupt the cellular defense mechanisms against oxidative damage. Nrf2 inhibitors have been studied in various biomedical contexts, including cancer research. In some cancer cells, Nrf2 is overexpressed, leading to increased antioxidant capacity and resistance to chemotherapy or radiation therapy. By inhibiting Nrf2, researchers aim to sensitize cancer cells to treatment and enhance the effectiveness of anticancer therapies. Moreover, Nrf2 inhibitors have also been investigated as potential therapeutic agents for other conditions associated with oxidative stress, such as neurodegenerative diseases, cardiovascular diseases, and inflammatory disorders. By modulating the Nrf2 pathway, these inhibitors may offer a way to restore redox balance and mitigate the detrimental effects of oxidative stress in these conditions. It is important to note that the development and use of Nrf2 inhibitors require careful consideration of their potential side effects and impact on normal cellular functions. While inhibiting Nrf2 may be beneficial in certain disease contexts, it may also disrupt the physiological antioxidant defense mechanisms and have unintended consequences. Therefore, further research and clinical trials are necessary to fully understand the therapeutic potential and safety profile of Nrf2 inhibitors.

Reata, Kyowa Kirin's bardoxolone faces the music after ph. 3 flop, ending 13-year saga

Kyowa Kiryin and Reata have worked together on bardoxolone for more than 13 years. Reata and Kyowa Kirin are burying bardoxolone methyl after new phase 3 data laid bare the dwindling—if not non-existent—potential of the kidney disease treatment. The two companies said that while the treatment hit the primary and secondary endpoints in a phase 3 trial testing bardoxolone in patients with diabetic kidney disease, there was no difference in the time to end-stage renal disease between treated patients and placebo. That was the nail in the coffin, with Kyowa and Reata saying Wednesday that they’ll end development of bardoxolone as a treatment for chronic kidney disease. Investors punished Reata for the disappointing conclusion, with shares down roughly 23% an hour after the market opened, from $105.37 down to $81. Thus ends an incredibly tumultuous saga for bardoxolone that’s extended some 13 years and spanned three different partnerships. Reata first handed over commercialization rights to certain markets to both Kyowa Kirin and Abbott (now AbbVie) back in 2009 and 2010, respectively, when bardoxolone was in phase 2 development for patients with diabetes who had chronic kidney disease. AbbVie double dipped a year later, offering up another $400 million to jointly develop and commercialize other Reata projects aimed at kidney and autoimmune diseases. But the wheels slowly, but surely, began to come off, beginning in 2012 when a phase 3 trial was halted after treated patients were experiencing higher rates of heart-related side effects, including hospitalizations and death. The company swiftly pivoted to aiming the treatment at patients with pulmonary arterial hypertension. Reata couldn’t just step away from the kidney ambitions, however, launching additional studies including one testing bardoxolone in patients with chronic kidney disease caused by Alport syndrome. AbbVie had enough, backing out in 2019 and recouping $330 million out of the original $850 million it handed over across the two deals. FDA advisors told Reata to go back to the drawing board two years later when they unanimously voted against the risk-benefit profile of bardoxolone kidney disease treatment in patients with Alport syndrome. The FDA formally rejected the med last year. Kyowa Kirin has dutifully held on throughout, launching a phase 3 study five years ago testing bardoxolone in diabetic patients with chronic kidney disease. But after the latest readout, the Japanese pharma said it no longer sees a viable regulatory route. The axed development plan has forced Reata to address a $350 million investment from Blackstone in 2020 to help develop bardoxolone, the majority of which was to be paid from royalties on the treatment. Reata says Blackstone will now receive single-digit royalties on Skyclarys (omaveloxolone), which was approved in March as a treatment for Friedreich’s ataxia and is one of two assets remaining in the company's pipeline. Reata's attention is now on the commercialization effort for Skyclarys. The company says it has received approximately 500 patient start forms since approval but doesn’t expect to be in specialty pharmacies until mid-August while the FDA reviews an NDA supplement submitted by Reata asking for an increase in drug substance specification. The company says approval of the supplement is required before the drug can be sent to pharmacies. Reata is also working on RTA 901 treatment for diabetic peripheral neuropathic pain, completing a phase 1 single ascending and multiple ascending dose study. The company planned to launch a phase 2 study in the second half of 2022 but it’s unclear if that’s happened. A phase 2 clinical trial record was not found on clinicaltrials.gov.

Reata culls bardoxolone, ending decade of R&D on troubled kidney disease drug

Reata’s long and winding road with bardoxolone appears to be over. The Plano, TX-based biotech and partner Kyowa Kirin said Wednesday morning that they are scrapping development of the asset in chronic kidney disease programs, which include CKD caused by Alport syndrome, people with diabetic CKD and a rare, hereditary form of the disease. With that, Reata expects to save more than $100 million previously set aside for the drug, a move that will push runway to the end of 2026, the company said in a presentation. Reata also disclosed a non-dilutive $275 million debt facility as part of its first-quarter update .
