Selcaxen 40mg Capsule (Selpercatinib) – Uses, Dosage, Side Effects & Price in Pakistan

Selcaxen 40mg Capsule contains selpercatinib, an oral targeted cancer medicine known as a selective RET kinase inhibitor. It is used for certain cancers that have specific abnormalities in the RET gene, including RET fusion-positive non-small cell lung cancer, RET-mutated medullary thyroid cancer, RET fusion-positive thyroid cancer, and certain advanced or metastatic solid tumors with RET gene fusions.

Selcaxen 40mg is a prescription oncology medicine and should be used only under the supervision of a qualified oncologist after appropriate molecular testing.

What Is Selcaxen 40mg Capsule?

Selcaxen 40mg Capsule contains selpercatinib 40mg. Selpercatinib is a small-molecule tyrosine kinase inhibitor designed to selectively target abnormal RET proteins.

RET alterations can cause abnormal signaling that encourages cancer cells to grow. Selpercatinib blocks RET activity and may help slow or stop the growth of cancers driven by these genetic changes.

The FDA-approved reference product Retevmo is available as 40mg and 80mg capsules, as well as tablet formulations.

Selcaxen 40mg Uses

Selpercatinib is used for specific cancers with confirmed RET abnormalities.

RET Fusion-Positive Non-Small Cell Lung Cancer

Selpercatinib is indicated for adults with locally advanced or metastatic non-small cell lung cancer (NSCLC) containing a RET gene fusion detected by an FDA-approved test.

RET-Mutated Medullary Thyroid Cancer

It is also used in adults and children aged 2 years and older with advanced or metastatic medullary thyroid cancer containing a RET mutation who require systemic treatment.

RET Fusion-Positive Thyroid Cancer

Selpercatinib may be used in adults and children aged 2 years and older with advanced or metastatic thyroid cancer containing a RET gene fusion who require systemic therapy and are radioactive-iodine refractory when radioactive iodine is appropriate.

RET Fusion-Positive Solid Tumors

Selpercatinib is also indicated for certain adults and children aged 2 years and older with locally advanced or metastatic solid tumors containing a RET gene fusion when the disease has progressed after prior systemic treatment or there are no satisfactory alternative treatment options.

How Does Selpercatinib Work?

Selpercatinib selectively inhibits the RET kinase. RET gene mutations and fusions can produce abnormal proteins that send signals promoting cancer-cell growth.

By blocking these abnormal RET proteins, selpercatinib can interfere with signaling pathways that cancer cells rely on for growth and survival.

Because the medicine specifically targets RET, testing for the relevant RET mutation or fusion is an important part of determining whether selpercatinib is appropriate.

Selcaxen 40mg Dosage

The recommended selpercatinib dose depends on body weight.

For adults and pediatric patients weighing 50kg or more, the recommended dose is:

• 160mg twice daily

For pediatric patients weighing less than 50kg:

• 120mg twice daily

The medicine is generally continued until disease progression or unacceptable toxicity. Your oncologist may reduce or interrupt treatment depending on side effects and laboratory results.

Because Selcaxen contains 40mg per capsule, the prescribed dose may require multiple capsules per administration.

Do not calculate or change your dose yourself. The number of capsules should always follow the prescription provided by your treating oncologist.

How to Take Selcaxen 40mg Capsule

• Take selpercatinib exactly as prescribed.
• It is generally taken twice daily, approximately 12 hours apart.
• It may be taken with or without food, depending on the formulation and prescribing instructions.
• Swallow the capsules whole with water.
• Do not crush or chew capsules.
• Take doses at approximately the same times every day.
• If you vomit after taking a dose, do not take an additional dose. Take the next dose at the scheduled time.
• If you miss a dose and it is less than 6 hours until the next dose, skip the missed dose and take the next dose at the regular time. Follow your prescribing information for specific missed-dose instructions.

Selcaxen 40mg Side Effects

Like other targeted cancer medicines, selpercatinib can cause side effects. Common adverse reactions reported with selpercatinib include:

• Dry mouth
• Diarrhea
• High blood pressure
• Increased liver enzymes
• Constipation
• Rash
• Headache
• Fatigue
• Swelling or edema
• Nausea
• Abdominal discomfort

The type and severity of side effects can vary depending on the patient’s condition and treatment regimen.

Serious Side Effects and Warnings

Liver Problems

Selpercatinib can cause liver toxicity, including increases in ALT and AST. Liver-function tests should be performed before treatment and monitored regularly during therapy.

Contact your healthcare team if you develop yellowing of the skin or eyes, dark urine, unusual tiredness, or persistent abdominal discomfort.

Interstitial Lung Disease and Pneumonitis

Selpercatinib can cause interstitial lung disease (ILD) or pneumonitis, which may be serious.

Report new or worsening cough, shortness of breath, chest discomfort, or difficulty breathing promptly.

High Blood Pressure

Selpercatinib may cause or worsen hypertension. Blood pressure should be checked regularly during treatment, particularly early in therapy.

QT Interval Prolongation

Selpercatinib can prolong the QT interval and may increase the risk of abnormal heart rhythms in susceptible patients. Your doctor may monitor ECGs and blood electrolyte levels when appropriate.

Bleeding

Serious bleeding events can occur with selpercatinib. Tell your doctor if you experience unusual or persistent bleeding.

Allergic Reactions

Hypersensitivity reactions may occur. Seek medical attention for swelling, difficulty breathing, severe rash, or other signs of a serious allergic reaction.

Selcaxen 40mg Capsule Precautions

Before taking Selcaxen, tell your doctor if you have:

• Liver disease
• High blood pressure
• Heart rhythm problems
• A history of prolonged QT interval
• Bleeding problems
• Lung disease
• Thyroid problems
• Previous allergic reactions to medicines
• A planned surgical procedure

Your doctor may perform blood tests, liver-function tests, blood-pressure checks, ECGs, and other monitoring during treatment.

Selcaxen 40mg Capsule (Selpercatinib) Drug Interactions

Selpercatinib can interact with several medicines.

The current prescribing information advises avoiding strong or moderate CYP3A inhibitors and inducers when possible because they can change selpercatinib exposure. Selpercatinib can also affect certain medicines metabolized by CYP enzymes.

Acid-reducing medicines require particular attention. The current label advises avoiding proton-pump inhibitors, H2-receptor antagonists, and antacids when possible, with specific administration instructions when these medicines are medically necessary.

Patients should also avoid St. John’s wort while taking selpercatinib.

Always tell your doctor about prescription medicines, over-the-counter products, vitamins, and herbal supplements.

Pregnancy and Breastfeeding

Selpercatinib may cause fetal harm. Women who can become pregnant should discuss effective contraception with their healthcare provider before and during treatment.

Patients who are pregnant, planning pregnancy, or breastfeeding should discuss the risks and benefits of treatment with their doctor.

Do not stop cancer treatment because of pregnancy without first speaking with your oncologist.
