Vimseltinib: uses, dosing, side effects & brands

The following clinically significant adverse reactions are described elsewhere in the labeling: Hepatotoxicity [see Warnings and Precautions ( 5.1 )] Most common adverse reactions (incidence ≥20%), including laboratory abnormalities are increased AST, periorbital edema, fatigue, rash, increased cholesterol, peripheral edema, face edema, decreased neutrophils, decreased leukocytes, pruritus, and increased ALT. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Deciphera Pharmaceuticals, LLC at 1-888-724-3274 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The pooled safety population described in the Warnings and Precautions reflects exposure to ROMVIMZA in 83 patients with TGCT enrolled in the double-blind portion and in 35 patients with TGCT in the open-label portion who crossed over to ROMVIMZA in MOTION, and in 135 patients with TGCT or solid tumors in other clinical trials. The safety of ROMVIMZA was evaluated in 83 adult patients with TGCT in MOTION [see Clinical Studies ( 14 )] . MOTION excluded patients with bilirubin, AST, or ALT >ULN. All patients received ROMVIMZA twice…

P-glycoprotein (P-gp) substrates : Avoid concomitant use with P-gp substrates. If concomitant use cannot be avoided, take ROMVIMZA at least 4 hours prior to P-gp substrates. ( 2.3 , 7.1 ) Breast Cancer Resistance Protein (BCRP) substrates : Avoid concomitant use with BCRP substrates. ( 7.1 ) Organic Cation Transporter 2 (OCT) substrates : Avoid concomitant use with OCT2 substrates. ( 7.1 ) 7.1 Effects of ROMVIMZA on Other Drugs Table 5 describes drug interactions where concomitant use with ROMVIMZA affects another drug. Table 5: Effect of ROMVIMZA on Other Drugs P-glycoprotein (P-gp) substrates Prevention or Management Avoid concomitant use with P-gp substrates while taking ROMVIMZA. If concomitant use cannot be avoided, take ROMVIMZA at least 4 hours prior to P-gp substrates [see Dosage and Administration ( 2.3 )] unless otherwise recommended in the substrate Prescribing Information. Mechanism and Clinical Effect(s) This recommendation is based upon a mechanistic understanding of vimseltinib pharmacokinetics and it being a P-gp inhibitor in vitro [see Clinical Pharmacology ( 12.3 )] . Concomitant use of ROMVIMZA with P-gp substrates may increase exposure of these substrates; however, this has not been studied clinically. Breast Cancer Resistance Protein (BCRP) substrates Prevention or Management Avoid concomitant use with BCRP substrates while taking ROMVIMZA. Refer to the Prescribing Information of the BCRP substrate for dose modifications if concomitant use cannot be avoided. Mechanism and Clinical Effect(s) This recommendation is based upon a mechanistic understanding of vimseltinib pharmacokinetics and it being a BCRP inhibitor in vitro [see Clinical Pharmacology ( 12.3 )] . Concomitant use of ROMVIMZA with BCRP substrates may increase exposure of these substrates; however, this has not been studied clinically. Organic Cation Transporter 2 (OCT2) substrates Prevention or Management Avoid concomitant use with OCT2 substrates while taking ROMVIMZA. Refer to the Prescribing Information of the OCT2 substrate for dose modifications if concomitant use cannot be avoided. Mechanism and Clinical Effect(s) This recommendation is based upon a mechanistic understanding of vimseltinib pharmacokinetics and it being an OCT2 inhibitor in vitro [see Clinical Pharmacology ( 12.3 )] . Concomitant use of ROMVIMZA with OCT2 substrates may increase exposure of these substrates; however, this has not been studied clinically.
