Mechanism of Disease
In PTEN-deficient mAPMN/S prostate cancer, 2 different pathways drive tumor growth1-3
The PI3K/AKT/PTEN pathway can independently drive tumor growth in PTEN-deficient mAPMN/S prostate cancer despite AR-targeted treatment3
Mechanism of Action
TRUQAP + abiraterone: The first and only combination that targets 2 critical pathways in PTEN-deficient mAPMN/S prostate cancer1,4
TRUQAP® (capivasertib) + abiraterone leverage the dual power of AKT inhibition + androgen biosynthesis inhibition to reduce signaling that drives tumor growth in these key pathways.3-6
As observed in preclinical models:

IMPORTANT SAFETY INFORMATION ABOUT TRUQAP® (capivasertib) tablets
IMPORTANT SAFETY INFORMATION ABOUT TRUQAP® (capivasertib) tablets
TRUQAP is contraindicated in patients with severe hypersensitivity to TRUQAP or any of its components.
Hyperglycemia
TRUQAP can cause severe hyperglycemia, including diabetic ketoacidosis and fatal outcomes
Metastatic HR-Positive, HER2-Negative Breast Cancer
PTEN-Deficient Metastatic Androgen Pathway Modulation-Naïve or -Sensitive Prostate Cancer
The safety of TRUQAP has not been established in patients with Type 1 diabetes or Type 2 diabetes that is uncontrolled or requiring insulin at baseline as these patients were excluded from clinical studies. Before initiating treatment with TRUQAP, test fasting glucose levels (FPG or FBG), HbA1C levels, and optimize fasting glucose. After initiating treatment with TRUQAP, monitor or self-monitor FG levels on Day 3 or 4 of the dosing week during weeks 1, 2, 4, 6, and 8; then monthly while on treatment with TRUQAP; and as clinically indicated. Monitor HbA1C levels every 3 months during treatment with TRUQAP and as clinically indicated. Patients with a history of well-controlled Type 2 diabetes mellitus may require intensified anti-hyperglycemic treatment and close monitoring of FG levels.
For patients who experience hyperglycemia during treatment with TRUQAP, monitor FG at least twice weekly, on days on and off TRUQAP, until FG decreases to baseline levels. During treatment with anti-diabetic medications, monitor FG at least once a week for 2 months, followed by once every 2 weeks, or as clinically indicated. Consider consultation with a healthcare practitioner with expertise in the treatment of hyperglycemia and initiation of FG monitoring at home for patients who have risk factors for hyperglycemia or who experience hyperglycemia. Advise patients on the signs and symptoms of hyperglycemia and counsel patients on lifestyle changes.
Withhold TRUQAP immediately when ketoacidosis is suspected. If ketoacidosis is confirmed, permanently discontinue TRUQAP. Withhold TRUQAP in clinical situations known to increase the risk of severe hyperglycemia or ketoacidosis (eg, suspected serious infection or acute illness). Based on the severity of hyperglycemia, withhold, reduce dose, or permanently discontinue TRUQAP.
Diarrhea
TRUQAP can cause severe diarrhea associated with dehydration
Metastatic HR-Positive, HER2-Negative Breast Cancer
PTEN-Deficient Metastatic Androgen Pathway Modulation-Naïve or -Sensitive Prostate Cancer
Monitor patients for signs and symptoms of diarrhea. Advise patients to increase oral fluids and start anti-diarrheal treatment at the first sign of diarrhea while taking TRUQAP. Withhold, reduce dose, or permanently discontinue TRUQAP based on severity.
Cutaneous Adverse Reactions
TRUQAP can cause cutaneous adverse reactions, which can be severe, including erythema multiforme (EM), palmar-plantar erythrodysesthesia (PPE), and drug reaction with eosinophilia and systemic symptoms (DRESS).
Metastatic HR-Positive, HER2-Negative Breast Cancer
PTEN-Deficient Metastatic Androgen Pathway Modulation-Naïve or -Sensitive Prostate Cancer
Monitor patients for signs and symptoms of cutaneous adverse reactions. Early consultation with a dermatologist is recommended. Withhold, reduce dose, or permanently discontinue TRUQAP based on severity.
Embryo-Fetal Toxicity
Based on findings from animals and mechanism of action, TRUQAP can cause fetal harm when administered to a pregnant woman. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Advise females of reproductive potential to use effective contraception during treatment with TRUQAP and for 1 month after the last dose.
Advise male patients with female partners of reproductive potential to use effective contraception during treatment with TRUQAP and for 4 months after the last dose.
TRUQAP is used in combination with fulvestrant or abiraterone. Refer to the full Prescribing Information of fulvestrant or abiraterone for pregnancy and contraception information.
ADVERSE REACTIONS
Metastatic HR-Positive, HER2-Negative Breast Cancer
PTEN-Deficient Metastatic Androgen Pathway Modulation-Naïve or -Sensitive Prostate Cancer
DRUG INTERACTIONS
Strong CYP3A Inhibitors: Avoid concomitant use with a strong CYP3A inhibitor. If concomitant use cannot be avoided, reduce the dose of TRUQAP and monitor patients for adverse reactions.
Moderate CYP3A Inhibitors: When concomitantly used with a moderate CYP3A inhibitor, reduce the dose of TRUQAP and monitor patients for adverse reactions.
Strong or Moderate CYP3A Inducers: Avoid concomitant use of TRUQAP with strong or moderate CYP3A inducers.
