Question 1

What is Qinlock?

Accepted Answer

Qinlock is a kinase inhibitor that works by blocking the action of abnormal proteins that signal cancer cells to multiply. By targeting these specific proteins, the medication helps to slow or stop the growth and spread of tumors.

This targeted approach is designed to interfere with the biological processes that allow cancerous cells to divide and expand within the body.

Question 2

What is Qinlock used for?

Accepted Answer

Qinlock is used to treat gastrointestinal stromal tumor .

Question 3

How does Qinlock work?

Accepted Answer

Mechanism of Action

Qinlock belongs to a class of medications known as kinase inhibitors. It is specifically designed to treat gastrointestinal stromal tumors (GIST) by targeting the underlying causes of cell growth.

Targeting Cancer Proteins

The medication works by interfering with the action of two specific proteins:

KIT

PDGFRA

In many cases of GIST, these proteins are mutated, causing them to stay in an "on" position. This sends continuous signals to cancer cells, telling them to divide and spread throughout the body.

Slowing Tumor Growth

Qinlock acts as a switch-control inhibitor. It binds to these proteins and blocks the signals they send. By inhibiting these pathways, the drug helps to:

Slow the growth of existing tumor cells.

Prevent the spread of the cancer to other parts of the body.

Target mutations that may have become resistant to other kinase inhibitor treatments.

Question 4

What are the active ingredients in Qinlock?

Accepted Answer

The active ingredient in Qinlock is ripretinib .

Question 5

What are the side effects of Qinlock?

Accepted Answer

Common side effects of Qinlock may include:

Alopecia

Fatigue

Nausea

and others.

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Qinlock?

Accepted Answer

Qinlock belongs to the tyrosine kinase inhibitor drug class.

Question 7

What is the dosage of Qinlock and how do I take it?

Accepted Answer

Qinlock is taken by mouth, usually once a day. It is important to take the medication at the same time every day to maintain a consistent level in your body. You can take the tablets with or without a meal.

The tablets should be swallowed whole. Do not crush, split, or chew them. If you vomit after taking your dose, do not take an extra tablet; simply wait until your next scheduled dose.

If you miss a dose, take it as soon as you remember on the same day. If a significant amount of time has passed since your scheduled dose, skip the missed dose and take the next one at your regular time. Do not take two doses at once to make up for a missed dose.

Question 8

Is Qinlock safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Qinlock can cause fetal harm when administered to a pregnant person. Animal studies indicate that the medication may cause birth defects or pregnancy loss. It is important to inform a healthcare provider if you are pregnant or planning to become pregnant before starting this medication.

Healthcare providers typically advise the following regarding pregnancy and contraception:

Pregnancy Testing: A pregnancy test is usually required for individuals who can become pregnant before starting treatment.

Contraception for Females: Use effective birth control during treatment and for at least 1 week after the final dose.

Contraception for Males: Males with female partners of reproductive potential should use effective birth control during treatment and for at least 1 week after the final dose.

Breastfeeding

It is not known whether ripretinib passes into human breast milk. Because of the potential for serious adverse reactions in a breastfed child, breastfeeding is not recommended during treatment with Qinlock and for at least 1 week after the last dose.

Fertility

Qinlock may impair fertility in both males and females of reproductive potential. This may affect the ability to father a child or become pregnant. Patients should discuss fertility concerns with their healthcare team before beginning treatment.

Question 9

What forms and strengths does Qinlock come in?

Accepted Answer

Qinlock is provided as a tablet for oral administration. It is intended to be swallowed whole and is taken by mouth on a daily schedule.

Question 10

What is the FDA approval status of Qinlock?

Accepted Answer

FDA Approval History

The U.S. Food and Drug Administration (FDA) approved Qinlock in May 2020. It was the first medication specifically approved as a fourth-line treatment for advanced gastrointestinal stromal tumors.

Approved Indications

Qinlock is indicated for the treatment of adult patients with advanced GIST who have previously been treated with three or more kinase inhibitors, including imatinib. It is used when the cancer has progressed or when other treatments are no longer effective.

Regulatory Status and Safety Monitoring

Qinlock is a prescription-only medication. At this time, the FDA does not require a boxed warning or a Risk Evaluation and Mitigation Strategy (REMS) for this drug. However, regulatory information indicates that healthcare providers must monitor patients for specific safety concerns, including:

Skin reactions: Monitoring for hand-foot skin reaction and other dermatological issues.

Cardiovascular health: Checking for new or worsening high blood pressure or heart failure.

New cancers: Monitoring for the development of new skin cancers (squamous cell carcinoma or keratoacanthoma) during treatment.

Question 11

What should I know about Qinlock and cost?

Accepted Answer

Insurance and Pharmacy Factors

The price of Qinlock is largely influenced by the type of health insurance plan a patient has, including private insurance or Medicare Part D. Because it is a specialized treatment for advanced gastrointestinal stromal tumors (GIST), it is typically dispensed through specialty pharmacies rather than standard retail pharmacies. These specialty pharmacies may have different pricing structures based on insurance contracts.

Out-of-Pocket Costs

Patients may be responsible for various out-of-pocket expenses, such as deductibles, co-payments, or co-insurance. The total cost will also depend on the prescribed dosage and the duration of the treatment as determined by a healthcare provider.

Financial Assistance

Assistance programs may be available to help reduce the cost for eligible patients. These can include manufacturer-sponsored co-pay cards for those with commercial insurance or patient assistance programs for individuals who are uninsured or underinsured. Patients are encouraged to discuss these options with their medical team or a specialty pharmacy coordinator.
