Drug forms and strengths

Truqap comes as tablets that you swallow whole. The drug is available in two strengths: 160 milligrams (mg) and 200 mg.

Dosage for breast cancer

The recommended dose of Truqap is 400 mg. You’ll take this dose twice daily (about 12 hours apart) for 4 days, followed by 3 days off each week.

Here is an example of a Truqap dosing schedule:

Some people may need to take a lower dose of Truqap. If you develop certain side effects, your doctor may have you stop Truqap treatment. If you restart it, they may prescribe a lower dose.

About taking Truqap

The recommended dose is 400 mg. This dose is taken by mouth as two 200-mg tablets. You can swallow them together or one after the other.

Below, you’ll find more information about key dosage issues.

  • When to take: On the days you take Truqap, you’ll take it twice daily. You’ll take one dose in the morning and one dose in the evening, approximately 12 hours apart. (For example, you can take one dose at 7 a.m. and one dose at 7 p.m.)
  • If you miss a dose: If you miss a dose of Truqap, your next step depends on when the dose was due. If you miss a dose and it’s been 4 hours or less since you were due to take it, take your dose as soon as possible. If it’s been more than 4 hours since you were due to take it, skip the missed dose. Just wait and take your next scheduled dose at the usual time.
  • If you vomit after taking Truqap: If you vomit after taking your Truqap dose, you should not take another dose. Just wait and take your next scheduled dose at the usual time.
  • Taking Truqap with food: You can take Truqap with or without food.
  • Crushing, splitting, or chewing Truqap: You’ll swallow Truqap tablets whole. These tablets should not be chewed, crushed, or split. You should not take Truqap tablets if they appear cracked or broken. Talk with your doctor if you have trouble swallowing Truqap tablets.
  • Length of use: Truqap is meant to be used as a long-term treatment. If you and your doctor determine that Truqap is safe and effective for you, you’ll likely take it long term.
  • Length of time to work: Truqap starts working with your first dose. But it may take a few weeks or months before your doctor can determine how well the drug is working for your cancer. They’ll use tests (such as scans) to check if your cancer is responding to treatment.

Truqap for breast cancer

Truqap is FDA-approved for treating breast cancer that includes all the following characteristics:

Truqap is FDA-approved for adults whose cancer meets all the criteria above and has progressed (gotten worse) during or after treatment with hormone therapy. For this purpose, Truqap is prescribed along with fulvestrant (Faslodex) for breast cancer.

Depending on certain biological factors, your doctor will prescribe another drug along with Truqap. For females* who haven’t yet entered menopause and males,* this includes a luteinizing hormone-releasing hormone (LHRH) agonist. An example of an LHRH agonist drug that may be prescribed with Truqap is goserelin (Zoladex).

If you can become pregnant, consider the following information about pregnancy, fertility, birth control, and breastfeeding.

Truqap and pregnancy

Truqap should not be taken during pregnancy. If you’re planning a pregnancy or can become pregnant, talk with your doctor before taking this medication. Your doctor may suggest birth control options to use during treatment with Truqap.

People who can become pregnant will need to take a pregnancy test before starting Truqap to confirm they’re not pregnant.

Truqap and birth control

Truqap is not safe to take during pregnancy. If you’re sexually active and you or your partner can become pregnant, talk with your doctor about your birth control needs while you’re using Truqap.

Note: Sex and gender exist on spectrums. Use of the terms “female” and “male” in this article refers to sex assigned at birth.

For females taking Truqap

Females who can become pregnant should use effective birth control during Truqap treatment and for 1 month after their last dose.

For males taking Truqap

Males with partners who can become pregnant should use an effective birth control method (such as condoms) during Truqap treatment and for 4 months after their last dose.

Truqap and breastfeeding

Truqap should not be taken while breastfeeding. If you’re currently breastfeeding or planning to do so, talk with your doctor before taking this medication. Your doctor may recommend other ways to feed your child during treatment with Truqap.

Here are answers to some frequently asked questions about Truqap.

How does Truqap work?

Truqap works by blocking certain AKT proteins, which are part of a signaling pathway that helps cells grow. This includes cancer cells. Truqap also targets other proteins in this pathway, including the PI3K and PTEN proteins.

In clinical trials, on average, people taking Truqap and fulvestrant lived longer before their cancer worsened compared with those who took a placebo and fulvestrant. (A placebo is a treatment with no active drug.) In these trials, some people taking Truqap had a partial response, and some had a complete response. With a partial response, the signs and symptoms of your cancer are decreasing. With a complete response, your cancer becomes undetectable on scans and other tests.

Talk with your doctor if you have questions about what to expect with Truqap treatment.

Does Truqap cause long-term side effects?

Possibly, but Truqap isn’t known to cause long-term side effects. No long-term side effects were specifically reported in clinical trials of the drug.

If you develop any side effects during Truqap treatment that don’t go away, talk with your doctor. They can advise you on how to manage your symptoms, which may include stopping the medication. And the drug’s side effects should ease or disappear soon after your last dose.

How does Truqap compare with Piqray?

Truqap and alpelisib (Piqray) are prescribed to treat certain types of breast cancer. They belong to the same group of drugs (kinase inhibitors), which are a type of targeted therapy. (“Targeted therapy” is a general category of treatments for cancer.)

These drugs have one target that’s the same, while Truqap has two additional targets. The targets are based on specific genetic mutations found in cancer cells.

Piqray blocks a type of protein called PI3K in cancer cells. PI3K helps the cancer grow. The drug is used in certain adults along with fulvestrant (Faslodex) to treat HR-positive, HER2-negative breast cancer that has a specific gene mutation called PIK3CA.

In contrast, Truqap blocks other proteins called AKT in cancer cells. AKT helps the cancer grow. The drug is used in certain adults along with fulvestrant (Faslodex) to treat HR-positive, HER2-negative breast cancer that has one or more specific gene mutations. These include PIK3CA, AKT1, and/or PTEN.

These drugs also have different dosages. Piqray is taken by mouth once a day. Truqap is taken twice a day for 4 days in a row, followed by 3 days off each week.

So far, the effectiveness of these two medications for breast cancer has not been compared in head-to-head clinical trials.

Talk with your doctor for additional information about how these drugs compare.

This drug comes with several precautions.

Before taking Truqap, discuss your health history with your doctor. Truqap may not be right for you if you have certain medical conditions or other factors affecting your health. Be sure to talk with your doctor if any of the following apply to you:
