The primary metabolic pathway is N-dealkylation, with CYP3A4 as the main contributor (83%) to total oxidative clearance of encorafenib in human liver microsomes, followed by CYP2C19 (16%) and CYP2D6 (1%) [FDA label].
In large clinical trials of the combination of encorafenib and binimetinib, abnormalities in routine liver tests were common and serum ALT elevations occurred in 26% of patients. ALT and AST values greater than 5 times the upper limit of normal (ULN) occurred in 6% and led to dose modification or discontinuation in 3.6% of patients. However, the aminotransferase abnormalities were generally transient and asymptomatic and there were no reports of clinically apparent liver injury with jaundice reported from the prelicensure studies. Since its approval and more widespread use, there have been no published instances of clinically apparent hepatotoxicity attributed to this combination therapy, but the total experience with its use has been limited.
New primary malignancies, cutaneous and non-cutaneous, have been observed in patients treated with BRAF inhibitors and can occur with encorafenib [FDA label] In COLUMBUS, a phase 3 safety and efficacy trial [FDA label], cutaneous squamous cell carcinoma (cuSCC), including keratoacanthoma (KA), occurred in 2.6%, and basal cell carcinoma occurred in 1.6% of patients who received BRAFTOVI in combination with binimetinib. The median time to first occurrence of cuSCC/KA was 5.8 months (range 1 to 9 months) [FDA label]. Tumor promotion in BRAF Wild-Type Tumors has been observed with encofarenib use [FDA label]. Hemorrhage, uveitis, QT interval prolongation are also other adverse events observed while taking this medication [FDA label]. Encorafenib, when used as a single agent, is associated with an increased risk of certain adverse reactions compared to when BRAFTOVI is used in combination with binimetinib. Grades 3 or 4 dermatologic reactions occurred in 21% of patients treated with BRAFTOVI therapy alone compared to 2% of patients treated with BRAFTOVI in combination with binimetinib [FDA label]. Advise females with reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective non-hormonal contraception during treatment with BRAFTOVI and for 2 weeks after the final dose [FDA label].

恩考拉非尼在体外与人血浆蛋白的结合率为86% [FDA标签]。
Encorafenib is 86% bound to human plasma proteins in vitro [FDA label].
After oral administration, the median Tmax of encorafenib is 2 hours. At least 86% of the dose is absorbed. Administration of a single dose of BRAFTOVI 100 mg (0.2 times the recommended dose) with a high-fat, high-calorie meal (comprised of approximately 150 calories from protein, 350 calories from carbohydrates, and 500 calories from fat) decreased the mean maximum encorafenib concentration (Cmax) by 36% with no effect on AUC (area under the curve) [FDA label].
Following a single oral dose of 100 mg radiolabeled encorafenib, 47% (5% unchanged) of the administered dose was recovered in the feces and 47% (2% unchanged) was recovered in the urine [FDA label].

The present invention provides highly active locked nucleic acid cyclic-dinucleotide (LNA-CDN) immune stimulators that activate DCs via the cytoplasmic receptor known as STING (Stimulator of Interferon Genes). In particular, the LNA-CDNs of the present invention are provided in the form of a composition comprising one or more cyclic dinucleotides that induce human STING-dependent type I interferon production, wherein the cyclic dinucleotides present in the composition have at least one 2′, 4′ locked nucleic acids within the cyclic dinucleotide.

Complete utilization of lignin: the methoxy groups in lignin react with carboxylicacids to generate methyl carboxylates (applied to the synthesis of pharmaceuticals), and the remaining carbon atoms of lignin react with oxygen to form CO predominantly, which may be used directly in carbonylation reactions.
