简介:

 

新型抗癌药BALVERSA(erdafitinib)片-获美国FDA加速批准用于治疗局部晚期或转移性尿路上皮癌。
近日,美国食品和药物管理局今天批准加速批准Balversa(erdafitinib)片剂上市,这是一种治疗患有局部晚期或转移性膀胱癌的成人患者,其具有一种易感基因改变,称为FGFR3或FGFR2,并且在之前或之后发展含铂化疗。应使用FDA批准的伴随诊断设备选择患者进行Balversa治疗。
此次获批准是第一个针对转移性膀胱癌患者的易感FGFR基因改变的个性化治疗,“FDA的肿瘤学博士,FDA肿瘤中心主任和FDA中心血液学和肿瘤学产品办公室代理主任医师Richard Pazdur说。药物评价与研究。“FGFR调节重要的生物过程,包括细胞生长和发育和组织修复过程中的分裂。该药通过靶向FGFR的遗传改变起作用。

BALVERSA(厄达替尼 [erdafitinib])片剂,用于口服
美国最初批准:2019年
作用机制
Erdafitinib是一种激酶抑制剂,可根据体外数据结合并抑制FGFR1,FGFR2,FGFR3和FGFR4的酶活性。Erdafitinib还与RET,CSF1R,PDGFRA,PDGFRB,FLT4,KIT和VEGFR2结合。Erdafitinib抑制FGFR磷酸化和信号传导,并降低表达FGFR遗传改变的细胞系中的细胞活力,包括点突变,扩增和融合。Erdafitinib在表达FGFR的细胞系和异种移植模型中显示出抗肿瘤活性源自肿瘤类型,包括膀胱癌。

BALVERSA(erdafitinib)
NDICATION
BALVERSA(erdafitinib)is a kinase inhibitor indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma that has
susceptible fibroblast growth receptor(FGFR)3 or FGFR2 genetic alterations and
progressed during or following at least one line of prior platinum-containing chemotherapy, including within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy.
Select patients for therapy based on an FDA-approved companion diagnostic for BALVERSA™.
IMPORTANT SAFETY INFORMATION
Ocular Disorders—BALVERSA™ can cause ocular disorders, including central serous retinopathy/retinal pigment epithelial detachment(CSR/RPED) resulting in visual field defect.
CSR/RPED was reported in 25% of patients treated with BALVERSA™, with a median time to first onset of 50 days. Grade 3 CSR/RPED, involving central field of vision, was reported in 3% of patients. CSR/RPED resolved in 13% of patients and was ongoing in 13% of patients at the study cutoff. CSR/RPED led to dose interruptions and reductions in 9% and 14% of patients, respectively, and 3% of patients discontinued BALVERSA™. Dry eye symptoms occurred in 28% of patients during treatment with BALVERSA™ and were Grade 3 in 6% of patients. All patients should receive dry eye prophylaxis with ocular demulcents as needed.
Perform monthly ophthalmological examinations during the first 4 months of treatment and every 3 months afterwards, and urgently at any time for visual symptoms. Ophthalmological examination should include assessment of visual acuity, slit lamp examination, fundoscopy, and optical coherence tomography. Withhold BALVERSA™ when CSR occurs and permanently discontinue if it does not resolve within 4 weeks or if Grade 4 in severity. For ocular adverse reactions, follow the dose modification guidelines [see Dosage and Administration].
Hyperphosphatemia–Increases in phosphate levels are a pharmacodynamic effect of BALVERSA[see Pharmacodynamics].
Hyperphosphatemia was reported as adverse reaction in 76% of patients treated with BALVERSA™. The median onset time for any grade event of hyperphosphatemia was 20 days(range: 8–116) after initiating BALVERSA™. Thirty-two percent of patients received phosphate binders during treatment with BALVERSA™. Monitor for hyperphosphatemia and follow the dose modification guidelines when required [see Dosage and Administration].
Embryo-fetal Toxicity – Based on the mechanism of action and findings in animal reproduction studies, BALVERSA™ can cause fetal harm when administered to a pregnant woman. In a rat embryo-fetal toxicity study, erdafitinib was embryotoxic and teratogenic at exposures less than the human exposures at all doses studied. Advise pregnant women of the potential risk to the fetus. Advise female patients of reproductive potential to use effective contraception prior to and during treatment, and for one month after the last dose. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with BALVERSA™ and for one month after the last dose[see Use in Specific Populations and Clinical Pharmacology].
Most common adverse reactions including laboratory abnormalities ≥20% were: Phosphate increased (76%), stomatitis (56%), fatigue (54%), creatinine increased (52%), diarrhea (47%), dry mouth (45%), onycholysis (41%), alanine aminotransferase increased (41%), alkaline phosphatase increased (41%), sodium decreased (40%), decreased appetite (38%), albumin decreased (37%), dysgeusia (37%), hemoglobin decreased (35%), dry skin (34%), aspartate aminotransferase increased (30%), magnesium decreased (30%), dry eye (28%), alopecia (26%), palmar-plantar erythrodysesthesia syndrome (26%), constipation (28%), phosphate decreased (24%), abdominal pain (23%), calcium increased (22%), nausea (21%), and musculoskeletal pain (20%). The most common Grade 3 or greater adverse reactions (>1%) were stomatitis (9%), nail dystrophy*, palmar-plantar erythrodysesthesia syndrome (6%), paronychia (3%), nail disorder*, keratitis†, onycholysis* (10%), and hyperphosphatemia.
Included within onycholysis. †Included within dry eye.
An adverse reaction with a fatal outcome in 1% of patients was acute myocardial infarction.
Serious adverse reactions occurred in 41% of patients, including eye disorders (10%).
Permanent discontinuation due to an adverse reaction occurred in 13% of patients. The most frequent reasons for permanent discontinuation included eye disorders (6%).
Dosage interruptions occurred in 68% of patients. The most frequent adverse reactions requiring dosage interruption included hyperphosphatemia (24%), stomatitis (17%), eye disorders (17%), and palmar-plantar erythrodysesthesia syndrome (8%).
Dose reductions occurred in 53% of patients. The most frequent adverse reactions for dose reductions included eye disorders (23%), stomatitis (15%), hyperphosphatemia (7%), palmar-plantar erythrodysesthesia syndrome (7%), paronychia (7%), and nail dystrophy (6%).
DRUG INTERACTIONS
Strong CYP2C9 or CYP3A4 Inhibitors: Consider alternative agents or monitor closely for adverse reactions.
Strong CYP2C9 or CYP3A4 inducers: Avoid concomitant use with BALVERSA™.
Moderate CYP2C9 or CYP3A4 inducers: Increase BALVERSA™ dose up to 9 mg.
Serum phosphate level-altering agents: Avoid concomitant use with agents that can alter serum phosphate levels before the initial dose modification period.
CYP3A4 substrates: Avoid concomitant use with sensitive CYP3A4 substrates with narrow therapeutic indices.
OCT2 substrates: Consider alternative agents or consider reducing the dose of OCT2 substrates based on tolerability.
P-gp substrates: Separate BALVERSA™ administration by at least 6 hours before or after administration of P-gp substrates with narrow therapeutic indices.
