Exploratory follow‑up analysis
PFS Forest Plot PFS Forest Plot

This analysis was exploratory in nature; it did not control for type 1 error and was not powered to determine treatment effect in any subgroup. Primary mutation status was retrospectively assessed in tumor samples by tumor biopsy from evaluable patients treated with Qinlock (n=73) and placebo (n=39).

Includes other KIT exon mutations, PDGFRα mutations, and KIT/PDGFRα wild-type patients.

§Includes patients who failed sequencing due to low tumor content and patients with no specimen.

Important Safety Information

There are no contraindications for Qinlock.

Palmar‑plantar erythrodysesthesia syndrome (PPES): In INVICTUS, Grade 1–2 PPES occurred in 21% of the 85 patients who received Qinlock. PPES led to dose discontinuation in 1.2% of patients, dose interruption in 2.4% of patients, and dose reduction in 1.2% of patients. Based on severity, withhold Qinlock and then resume at same or reduced dose.

New Primary Cutaneous Malignancies: In INVICTUS, cutaneous squamous cell carcinoma (cuSCC) occurred in 4.7% of the 85 patients who received Qinlock with a median time to event of 4.6 months (range 3.8 to 6 months). In the pooled safety population, cuSCC and keratoacanthoma occurred in 7% and 1.9% of 351 patients, respectively. In INVICTUS, melanoma occurred in 2.4% of the 85 patients who received Qinlock. In the pooled safety population, melanoma occurred in 0.9% of 351 patients. Perform dermatologic evaluations when initiating Qinlock and routinely during treatment. Manage suspicious skin lesions with excision and dermatopathologic evaluation. Continue Qinlock at the same dose.

Hypertension: In INVICTUS, Grade 1–3 hypertension occurred in 14% of the 85 patients who received Qinlock, including Grade 3 hypertension in 7% of patients. Do not initiate Qinlock in patients with uncontrolled hypertension. Monitor blood pressure as clinically indicated. Based on severity, withhold Qinlock and then resume at same or reduced dose or permanently discontinue.

Cardiac Dysfunction: In INVICTUS, cardiac failure occurred in 1.2% of the 85 patients who received Qinlock. In the pooled safety population, cardiac dysfunction (including cardiac failure, acute left ventricular failure, diastolic dysfunction, and ventricular hypertrophy) occurred in 1.7% of 351 patients, including Grade 3 adverse reactions in 1.1% of patients.

In INVICTUS, Grade 3 decreased ejection fraction occurred in 2.6% of the 77 patients who received Qinlock and who had a baseline and at least one post‑baseline echocardiogram. Grade 3 decreased ejection fraction occurred in 3.4% of the 263 patients in the pooled safety population who received Qinlock and who had a baseline and at least one post‑baseline echocardiogram.

In INVICTUS, cardiac dysfunction led to dose discontinuation in 1.2% of the 85 patients who received Qinlock. The safety of Qinlock has not been assessed in patients with a baseline ejection fraction below 50%. Assess ejection fraction by echocardiogram or MUGA scan prior to initiating Qinlock and during treatment, as clinically indicated. Permanently discontinue Qinlock for Grade 3 or 4 left ventricular systolic dysfunction.

Risk of Impaired Wound Healing: Qinlock has the potential to adversely affect wound healing. Withhold Qinlock for at least 1 week prior to elective surgery. Do not administer for at least 2 weeks following major surgery and until adequate wound healing. The safety of resumption of Qinlock after resolution of wound healing complications has not been established.

Embryo‑Fetal Toxicity: Qinlock can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. Advise females of reproductive potential and males with female partners of reproductive potential to use effective contraception during treatment and for at least 1 week after the final dose. Because of the potential for serious adverse reactions in the breastfed child, advise women not to breastfeed during treatment and for at least 1 week after the final dose. Qinlock may impair fertility in males of reproductive potential.

Adverse Reactions: The most common adverse reactions (≥20%) were alopecia, fatigue, nausea, abdominal pain, constipation, myalgia, diarrhea, decreased appetite, PPES, and vomiting. The most common Grade 3 or 4 laboratory abnormalities (≥4%) were increased lipase and decreased phosphate.

The safety and effectiveness of Qinlock in pediatric patients have not been established.

Administer strong CYP3A inhibitors with caution. Monitor patients who are administered strong CYP3A inhibitors more frequently for adverse reactions. Avoid concomitant use with strong and moderate CYP3A inducers. If a moderate CYP3A inducer cannot be avoided, increase Qinlock dosing frequency from the recommended dose of 150 mg once daily to 150 mg twice daily during the co‑administration period. If the concomitant moderate CYP3A inducer is discontinued, resume Qinlock dosage back to 150 mg once daily 14 days after the discontinuation of the moderate CYP3A inducer.

Indication

Qinlock is a kinase inhibitor indicated for the treatment of adult patients with advanced gastrointestinal stromal tumor (GIST) who have received prior treatment with 3 or more kinase inhibitors, including imatinib.
