A new treatment could reduce degeneration of intervertebral discs of the lower back. They chose the increasingly popular senolytic cocktail of dasatinib and quercetin, commonly known as D + Q. Since D is a multikinase inhibitor, it is possible that inhibition of VEGF receptors can promote endothelial dysfunction, inhibiting angiogenesis, and leading to microvascular infarctions. The second case was bilateral and occurred in a patient shortly after initiation of D who had a reduced platelet count (although not to the point of expecting spontaneous bleeding) (Yhim et al., 2012). A second meta-analysis (n=2182) also reported an incidence of rash at 22% (less than 1% classified as serious) ( Lindauer & Hochhaus, 2018) anda 7% incidence of pruritis. How likely adverse effects are to occur with intermittent combined D+Q treatment is largely unknown. More research is needed to determine whether quercetin can remove senescent cells in vivo, but the early evidence suggests that it could be a promising treatment for age-related diseases. It works by inhibiting the action of certain enzymes that are involved in the growth of cancer cells. Analysis of quercetin metabolites in plasma and liver have shown that the concentrations of its derivatives in the liver were lower than those in plasma, and the hepatic metabolites were extensively methylated (90%95%) (Li et al., 2016). However, more research is needed to confirm this. Anorexia was reported by many studies at frequencies between 17-69%. Rare cases may require thoracocentesis and oxygen therapy (Lindauer & Hochhaus, 2018). A research study applied a combination of 100mg of Dasatinib and 500mg of Quercetin to participants over a three days course. According to a study at Pompeu Fabra University (UPF) led by scientists from Altos Labs Inc., cell damage caused the senescence of the cells, which secreted toxic substances into the surrounding microenvironment, causing . Studies reporting pleural effusion as an adverse effect. In vitroquercetin has been shown to cause mutations, chromosomal aberrations, DNA single-strand breaks, and the induction of micronuclei. in NAD+ Started by Fredrik, . Increased risk of various types of infections, including atypical infections, has been reported. One study reported that 5% (2/40) patients developed chest pain (Bergeron et al., 2007). Dizziness was experienced by 13% of patients in a 6-month trial that used D to treat systemic sclerosis-associated interstitial lung disease although the cases believed to be caused by D were only 3.2% (Martyanov et al., 2017). Bronchial wall thickening was reported as a severe adverse event in one trial but the authors did not provide the time of onset (Takahashi et al., 2011). Most cases were mild with 1-5% being graded as severe (Shah et al., 2008). A second study reported significantly improved glucose tolerance and insulin sensitivity following D+Q (5+50 mg/kg) for either 5 consecutive days monthly or 3 consecutive days with 14 days between treatment rounds. Quercetin is a natural compound found in fruits, vegetables, and herbs. An open-label trial reported improvements in physical function that included improved 6-min walk distance, 4-m gait speed, and 5-repeated chair-stand times (Justice et al., 2019). But opting out of some of these cookies may have an effect on your browsing experience. However, in control mice fed quercetin, the results were not significant (Kim et al., 2019). Treatment with Q (30 mg/kg intraperitoneally, over a period of 1 or 3 weeks also reduced p21 expression in bleomycin-induced lung injury in aged mice at 14 days (Hohmann et al., 2018). The number of p16INK4a+ cells was reduced by 35% in adipose tissue biopsies and 20% in the epidermal layer (although the result did not reach statistical significance). This risk-benefit analysis is part of Forever Healthy's "Rejuvenation Now" initiative that seeks tocontinuously identifypotential rejuvenation therapies and systematically evaluate their risks, benefits, and associated therapeutic protocolstocreate transparency. A phase 2 trial (n=200) reported that 6% of patients developed hyperglycemia but the time of onset was not provided (Schuetze et al., 2015). Curcumin, Polydatin and Quercetin Synergistic Activity Protects from High-Glucose-Induced Inflammation and Oxidative Stress. Src tyrosine kinase is expressed abundantly in vascular tissue, and activation of Src appears to play a crucial role in smooth muscle cell proliferation and vasoconstriction. Sprycel can be purchased for less than this price if ordered from outside the United States. The study was conducted in mice with leukemia, and the results showed that the combination of dasatinib and quercetin was more effective than either drug alone in killing leukemia cells. Another open-label trial (n=54) reported infection as an adverse event in 1.9% of patients (Wong et al., 2018). However, other studies have not found any evidence that quercetin causes liver damage. A study of genetic clearance of senolytic cells has shown a delay in wound healing and increased fibrosis after the wound is healed (Demaria et al., 2014). Nonetheless, quercetin is a safe and relatively inexpensive compound, and it may be worth considering as a potential senolytic agent. Elimination of senescent cells has been shown to both prevent and alleviate physical dysfunction in mice (Xu et al., 2018). A second systematic review of 3043 patients found an odds ratio of 3.86 for vascular occlusive events in D compared to Imatinib (Douxfils et al., 2016), a first-generation TKI. There was no mention of the time of onset. In an in vitro study on hepatocellular carcinoma cell lines, D+Q had no effect in removing SABGal+ cells that had been induced by treatment with doxorubicin (Kovacovicova et al., 2018). Hair and skin depigmentation have also been reported in several case reports. Two open-label trials reported that 10 and 11% of subjects, developed a cough while on D but did not give the time of onset (Schuetze et al., 2015;Apperley et al., 2009). Senescent cells accumulate with age, and are thought to contribute to age-related disorders such as arthritis, cataracts, and diabetes. Furthermore, a decreased urinary albumin to creatinine ratio (ACR), an indicator of renal dysfunction, was reported. The third trial is a randomized control trial (RCT) of low quality but did have 4 test groups (D+Q, D+placebo, Q+placebo, placebo+placebo) and enrolled healthy participants (Tkemaoadze & Apkjazava, 2019). Additionally, several patients experienced increased respiratory symptoms (edema, effusion, dyspnea), as well as headaches and GI discomfort that were mostly mild to moderate in severity,reversible, without sequelae, and consistent with events reported in the placebo arms of RCTs. Senolytics are a cocktail to drugs including both Dasatinib (a leukemia drug) and Quercetin (a natural plant compound) that have been proved to decrease the amount of zombie cells and rejuvenate worn out tissue and organs by selectively inducing apoptosis. Myalgia has been reported as a side effect of D in several studies. Which of the available methods are safe for use? There is some evidence that quercetin may have a tumor enhancing effect in combination with certain substances (estrogen). Additionally, D decreases thrombus formation and decreases phosphatidylserine-exposing (procoagulant) platelets (Haguet et al., 2018). Severe cases occurred in only 1-4% of subjects within the trials. Senescent cells acquire a proinflammatory secretory phenotype, called SASP, exacerbating and perpetuating the detrimental effects of hyperglycemia. Applies to dasatinib: oral tablets. It has been shown that the simultaneous ingestion of quercetin and vitamin C, folate or other flavonoids improves its bioavailability (Li et al., 2016). The changes in multiple tissues (skin, adipose tissue, plasma) suggest that oral administration of D+Q decreases overall senescent cell burden rather than targeting cells within a single organ or structure (Hickson et al., 2019). In the second study, a dose-dependent effect was found with protective effects at 10 mg/kg/day and prooxidative and pro-inflammatory effects at 100 mg/kg/day (Andres et al., 2017). More research is needed to determine whether quercetin has senolytic activity and, if so, what dose is necessary to achieve this effect. It is a type of drug known as a tyrosine kinase inhibitor. Q has also been shown to reduce the expression of p19-ARF in the lungs (Hohmann et al., 2018) and kidneys (Kim et al., 2019) of aged and high-fat diet-fed mice, respectively. We identified 56 risks that have occurred with D or Q therapy (Table 5). Cellular senescence was shown to drive NAFLD and D + Q treatment could alleviate this pathology [18,19,20].However, these previous reports did not analyze the effectiveness of these senolytics in hampering the progression of NAFLD into inflammatory states and . Once absorbed into the blood, > 90% of the dasatinib molecules are bound to serum proteins. A corrigendum with a reanalysis of data from one of the trials was also included (Hickson et al., 2020). The initial blood pressure in all groups was approximately 115 mmHg and decreased to 108 mmHg in the D+Q group at 10 minutes after the completion of the "stair-ascending test" while the BP of the control group decreased to 112 mmHg. They were discovered with a mechanism-based approach targeting senescent cells instead of the random high-throughput method recommended for drug discovery. D+Q administration has also been shown to affect trabecular bone microarchitecture positively (Farr et al., 2017). Two case reports involved spontaneous subdural hematomas in patients receiving D. The first patient had a normal platelet count (Mustafa Ali et al., 2014). Clipboard, Search History, and several other advanced features are temporarily unavailable. The first human trial using both drug combinations showed a significant increase in improving physical functions in subjects with cellular senescence-driven diseases. Of those 13 trials, only 6 reported a positive effect of D+Q senolytic treatment on aged, otherwise healthy animals as compared to controls. Physical function tests, subjective questionnaires, and plasma measurements of SASP factors are, at the moment the best form of treatment monitoring available in clinical practice based on clinical trial evidence, Patients should be screened for preexisting heart/pulmonary conditions before beginning and during treatment, Clinical data on the possible benefits and risks of using D+Q as senolytics is extremely limited. The desire to live longer may be a possibility in the future if the pharmaceutical combination of anti-aging drugs is proven for wider population use. In a rodent study involving the subcutaneous transfer of hepatocellular carcinoma cells onto the dorsal flank of immunodeficient mice, with subsequent administration of D+Q, it was shown that the average tumor volume in the D+Q group was 50% more than the mice in the control group ( Kovacovicova et al., 2018). The total amount recovered in urine, feces and exhaled air is highly variable, depending on the individual. Most excretion is by way of feces. These cookies do not store any personal information. There is a group of core proteins that were elevated in all types of senescent cells, by all types of inducers. Senescent cells play a key role in the initiation and development of various age-related diseases. We now report results from directly comparing D+Q to fisetin (FIS) to determine differences in efficacy, toxicity, and sex and genotype as we work to translate this therapy to clinical studies. Hyperlipidemia has also been reported as an adverse effect of D. In a retrospective analysis (n= 845), it was reported to occur with an incidence rate of 46.4 per 1000 person-years (Franklin et al., 2017). It is suggested that once flavonoids are incorporated into cells, they can increase intracellular ROS levels, and then exert cytotoxicity (, Very little is known about the potential side effects of senolytic drugs as a class. A literature search was conducted on PubMed and the Cochrane Library using the search terms shown in Table 1and includes results available as of April 17, 2020. Q is well tolerated and has a very low incidence of adverse effects (Andres et al., 2017). Copyright 2023, EASYCOCKTAILIDEAS - All Rights Reserved. We further confirm that D+Q alleviate HUVECs senescence via the TNF receptor-associated factor 6 (TRAF6)-MAPK pathway. There was no evident decline in renal or hepatic function or evidence of cell lysis syndrome (Justice et al., 2019). Muscle cramps were also reported as an adverse effect in 8.8% of patients (n=69)(Chen et al., 2018). Many of the adverse effects have been shown to be correlated with dose and duration. Insomnia that resulted in only 2-3 hours of sleep was also described in a case report in which thepatient was taking a lower dose of dasatinib, 25 mg/day on alternate weeks, although he had taken higher doses in the past (Sami et al., 2014). D+Q also displayed a pro-tumorigenic effect in vitro in the same study. Titles and abstracts of the resulting studies were screened and relevant articles downloaded in full text. Elimination is quite slow, with a reported half-life ranging from 11 to 28 h and an average terminal half-life of 3.5 h (Li et al., 2016). FOIA Dasatinib dissolves better in low pH values, leading to more of the drug being absorbed into the blood. This protein is involved in the growth and spread of cancer cells. Senolytic treatment in aged mice clears senescent cell burden leading to functional improvements. The criteria are weighted on a value scale to enable comparison (based on the relative importance of a difference). Your email address will not be published. In the clinical trials, the reported adverse events were mostly mild to moderate in severity, reversible, without sequelae, and consistent with events reported in the placebo arms of RCTs. The experiment stopped at 23 months, a respectable old age for mice. Fever (along with painful subcutaneous nodules) was reported after 4 weeks of D therapy, resolved with cessation of D, and then recurred upon rechallenge (Brazzelli et al., 2013). Only one episode was associated with neutropenia. This category only includes cookies that ensures basic functionalities and security features of the website. Treatment with D treatment has been shown to decrease the volume of thrombi formed under arterial flow conditions in whole blood and to increase tail bleeding time in a dose-dependent and rapidly reversible manner (Gratacap et al., 2009). Alternatively, PE may occur due to inhibition of platelet-derived growth factor receptor- or Src-family kinases (Hughes et al., 2019). This site needs JavaScript to work properly. The risk of developing a PE was not significantly different between years 1-5.

In a small, open-label, phase 1 pilot study of seven patients with diabetic kidney disease, administration of once daily oral dasatinib (100 mg) and . Senescent cells contain factors that can cause inflammation and cell dysfunction. Thrombotic microangiopathies were also described in two case reports (Demirsoy et al., 2018; Martino et al., 2013). diabetic mice) and did not extend to control populations that received treatment with D+Q.

Thyroid abnormalities were reported in 70% of patients under treatment with D in one small trial (n=10) (Kim et al., 2010). An open-label trial (n=54) reported that 5.6% of subjects experienced chills while on D (Wong et al., 2018). Hickson LJ, Langhi Prata LGP, Bobart SA, Evans TK, Giorgadze N, Hashmi SK, Herrmann SM, Jensen MD, Jia Q, Jordan KL, Kellogg TA, Khosla S, Koerber DM, Lagnado AB, Lawson DK, LeBrasseur NK, Lerman LO, McDonald KM, McKenzie TJ, Passos JF, Pignolo RJ, Pirtskhalava T, Saadiq IM, Schaefer KK, Textor SC, Victorelli SG, Volkman TL, Xue A, Wentworth MA, Wissler Gerdes EO, Zhu Y, Tchkonia T, Kirkland JL. Its absorption is affected by differences in its glycosylation, the food matrix from which it is consumed, and the co-administration of dietary components such as fiber and fat (Guo et al., 2013). This is supported by two other studies examining the effects of Q in chemically-induced nephrotoxicity in male rats (Andres et al., 2017). The most distinguishing event was myocardial infarction, where seven patients in the D group and one patient in the placebo arm experienced a heart attack. A single 5-day course of D+Q also alleviated the effects of transplanting senescent cells after they were already established.
