Ripretinib is an oral tyrosine kinase inhibitor (TKI) used to treat adults with advanced gastrointestinal stromal tumors (GIST) who have previously received treatment with at least three kinase inhibitors, including imatinib. It works by blocking abnormal KIT and PDGFRA proteins that drive tumor growth.
Ripretinib
Ripretinib (Qinlock) is a targeted prescription medicine given in adults with advanced gastrointestinal stromal tumors (GIST) who have already undergone three or more kinase inhibitor treatments including Imatinib. It slows down tumor growth by blocking particular KIT and PDGFRA cell receptors, acting as a switch-control tyrosine kinase inhibitor.
Strength:
50 mg tablets
Dosage:
150 mg orally once daily with or without food
Adverse Reactions:
The most common adverse reactions (20%) were alopecia, fatigue, nausea, abdominal pain, constipation, myalgia, diarrhea, decreased appetite, palmarplantar erythrodysesthesia, and vomiting. The most common Grade 3 or 4 laboratory abnormalities (4%) were increased lipase and decreased phosphate.
Storage:
- Store Ripretinib in the original container at room temperature between 68 0 F to 77 0 F (200 C to 250 C).
- Ripretinib comes with a desiccant packet in the bottle to protect your medicine from moisture. Do not remove the desiccant packet from the bottle.
- Palmar-Plantar Erythrodysesthesia Syndrome: Based on severity, withhold Ripretinib and resume at same or reduced dose.
- New Primary Cutaneous Malignancies: Perform dermatologic evaluations when initiating Ripretinib and routinely during treatment.
- Hypertension: Do not initiate Ripretinib in patients with uncontrolled hypertension and monitor blood pressure during treatment. Based on severity, withhold Ripretinib and then resume at same or reduced dose or permanently discontinue.
- Cardiac Dysfunction: Assess ejection fraction by echocardiogram or MUGA scan prior to initiating Ripretinib and during treatment, as clinically indicated. Permanently discontinue Ripretinib for Grade 3 or 4 left ventricular systolic dysfunction.
- Risk of Impaired Wound Healing: Withhold Ripretinib for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks after major surgery and until adequate wound healing. The safety of resumption of Ripretinib after resolution of wound healing complications has not been established.
- Photosensitivity: May cause photosensitivity reactions. Advise patients to limit direct ultraviolet exposure.
- Embryo-Fetal Toxicity: Can cause fetal harm. Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception.
FAQ
How does Ripretinib work?
Ripretinib (Qinlock) is a “switch-control” kinase inhibitor that blocks a broad range of KIT and PDGFRA mutations responsible for GIST growth. By inhibiting these proteins, it slows or stops cancer cell proliferation.
How Are Ripretinib Tablets Taken?
The recommended dose is 150 mg orally once daily, with or without food. Tablets should be swallowed whole and taken at the same time each day.
What should I do if I miss a dose?
If you miss a dose and the next scheduled dose is more than 8 hours away, take the missed dose as soon as you remember. If it is less than 8 hours before the next dose, skip the missed dose and continue with your regular schedule. Do not take two doses together.
What serious side effects can occur with Ripretinib?
Serious side effects may include:
- High blood pressure
- Heart dysfunction
- Severe skin reactions
- New skin cancers, including melanoma
- Impaired wound healing
- Photosensitivity
- Embryo-fetal toxicity
Patients should undergo regular monitoring during treatment.
How long should patients continue taking Ripretinib?
Treatment is usually continued until disease progression or unacceptable toxicity occurs, unless otherwise directed by the treating physician.
