RARITAN, N.J. - The Janssen Pharmaceutical Companies of Johnson & Johnson announced new data demonstrating robust prostate-specific antigen (PSA) response and strong adherence rates in patients with non-metastatic castration-resistant prostate cancer (nmCRPC) treated with ERLEADA (apalutamide) in the real-world clinical setting. The strong PSA response was also seen in a separate post-hoc analysis that showed a correlation between rapid and deep PSA response and prolonged survival in both metastatic castration-sensitive prostate cancer (mCSPC) and nmCRPC. The post-hoc analysis also supports the use of PSA as a predictive biomarker in the treatment of patients with advanced prostate cancer. These findings were presented during two podium sessions at the virtual American Urological Association Annual Meeting (AUA 2021), September 10-13.

The post-hoc analysis (Abstract #PD34-11) of the Phase 3 TITAN and SPARTAN studies examined PSA kinetics in 2,259 patients with either mCSPC (TITAN) or nmCRPC (SPARTAN). Results showed that patients with advanced prostate cancer, whether mCSPC or nmCRPC, treated with ERLEADA plus androgen deprivation therapy (ADT) had rapid, deep and durable PSA declines as early as three months and continuing beyond a year after initiating ERLEADA therapy.1 In mCSPC (TITAN), the percentage of patients with a PSA decline of ?50 percent or ?90 percent or with an undetectable PSA (50 percent reduction in PSA by three months, and maintained that response 12 months after initiating ERLEADA.4

'Outside of a clinical trial setting, healthcare professionals are focused on ensuring a therapy can benefit patients treated in the real world. To have both high adherence rates and robust PSA reductions is very encouraging,' said Benjamin Lowentritt, M.D., Director Prostate Cancer Care Program, Chesapeake Urology, and Immediate Past President, AUA, Mid-Atlantic Region and lead study investigator. These findings support the use of apalutamide in delaying disease progression and metastasis in patients with nmCRPC across various demographics.'

To date, published results on ERLEADA include data from more than 2,000 patients across three Phase 3 clinical studies. ERLEADA has shown a statistically significant improvement in overall survival with a consistent safety profile, while maintaining health-related quality of life in both approved indications of mCSPC and nmCRPC.[4] ERLEADA is currently approved in more than 74 countries.

About ERLEADA

ERLEADA is an androgen receptor inhibitor indicated for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) and for the treatment of patients with metastatic castration-sensitive prostate cancer (mCSPC).4 ERLEADA received U.S. Food and Drug Administration (FDA) approval for nmCRPC on February 14, 2018 and was approved for mCSPC on September 17, 2019.4 To date, more than 40,000 patients worldwide have been treated with ERLEADA. ERLEADA is taken orally, once daily, with or without food.4 The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prostate Cancer include apalutamide (ERLEADA) with continued androgen deprivation therapy**(+) as a Category 1 Preferred treatment option for patients with non-metastatic (M0) castration-resistant prostate cancer and a PSADT ?10 months.[5] The NCCN Clinical Practice Guidelines also include apalutamide (ERLEADA) with androgen deprivation**(+) as a Category 1 Preferred treatment option for patients with metastatic (M1) castration-naive prostate cancer.(++)5 The American Urological Association (AUA) Guidelines for Castration-Resistant Prostate Cancer (CRPC) recommend clinicians offer apalutamide (ERLEADA) with continued androgen deprivation therapy (ADT) as one of the treatment options for patients with nmCRPC at high risk for developing metastatic disease (Standard; Evidence Level Grade A)***.[6] ERLEADA is being further studied in two ongoing Phase 3 clinical trials.

Orchiectomy, LHRH agonist, or LHRH antagonist

Use of an LHRH agonist plus a first-generation antiandrogen is an option for patients receiving ADT alone, but is not an option for patients receiving apalutamide.

The term 'castration-naive' is used to define patients who are not on ADT at the time of progression. The NCCN Prostate Cancer Panel uses the term 'castration-naive' even when patients have had neoadjuvant, concurrent, or adjuvant ADT as part of radiation therapy provided they have recovered testicular function.

Standard: Directive statement that an action should (benefits outweigh risks/burdens) or should not (risks/burdens outweigh benefits) be taken based on Grade A or B evidence.

Evidence Level: A designation indicating the certainty of the results as high, moderate, or low (A, B, or C, respectively) based on AUA nomenclature and methodology.

ERLEADA IMPORTANT SAFETY INFORMATION4 WARNINGS AND PRECAUTIONS

Cerebrovascular and Ischemic Cardiovascular Events - In a randomized study (SPARTAN) of patients with nmCRPC, ischemic cardiovascular events occurred in 4% of patients treated with ERLEADA and 3% of patients treated with placebo. In a randomized study (TITAN) in patients with mCSPC, ischemic cardiovascular events occurred in 4% of patients treated with ERLEADA and 2% of patients treated with placebo. Across the SPARTAN and TITAN studies, 5 patients (0.5%) treated with ERLEADA and 2 patients (0.2%) treated with placebo died from an ischemic cardiovascular event. Patients with history of unstable angina, myocardial infarction, congestive heart failure, stroke, or transient ischemic attack within 6 months of randomization were excluded from the SPARTAN and TITAN studies.

In the SPARTAN study, cerebrovascular events occurred in 4.7% of patients treated with ERLEADA and 0.8% of patients treated with placebo. In the TITAN study, cerebrovascular events occurred in 1.9% of patients treated with ERLEADA and 2.1% of patients treated with placebo. Across the SPARTAN and TITAN studies, 3 patients (0.2%) treated with ERLEADA, and 2 patients (0.2%) treated with placebo died from a cerebrovascular event.

Cerebrovascular and ischemic cardiovascular events, including events leading to death, occurred in patients receiving ERLEADA. Monitor for signs and symptoms of ischemic heart disease and cerebrovascular disorders. Optimize management of cardiovascular risk factors, such as hypertension, diabetes, or dyslipidemia. Consider discontinuation of ERLEADA for Grade 3 and 4 events.

Fractures - In a randomized study (SPARTAN) of patients with nmCRPC, fractures occurred in 12% of patients treated with ERLEADA and in 7% of patients treated with placebo. In a randomized study (TITAN) of patients with mCSPC, fractures occurred in 9% of patients treated with ERLEADA and in 6% of patients treated with placebo. Evaluate patients for fracture risk. Monitor and manage patients at risk for fractures according to established treatment guidelines and consider use of bone-targeted agents.

Falls - In a randomized study (SPARTAN), falls occurred in 16% of patients treated with ERLEADA compared with 9% of patients treated with placebo. Falls were not associated with loss of consciousness or seizure. Falls occurred in patients receiving ERLEADA with increased frequency in the elderly. Evaluate patients for fall risk.

Seizure - In 2 randomized studies (SPARTAN and TITAN), 5 patients (0.4%) treated with ERLEADA and 1 patient treated with placebo (0.1%) experienced a seizure. Permanently discontinue ERLEADA in patients who develop a seizure during treatment. It is unknown whether anti-epileptic medications will prevent seizures with ERLEADA. Advise patients of the risk of developing a seizure while receiving ERLEADA and of engaging in any activity where sudden loss of consciousness could cause harm to themselves or others.

Embryo-Fetal Toxicity - The safety and efficacy of ERLEADA have not been established in females. Based on its mechanism of action, ERLEADA can cause fetal harm and loss of pregnancy when administered to a pregnant female. Advise males with female partners of reproductive potential to use effective contraception during treatment and for 3 months after the last dose of ERLEADA [see Use in Specific Populations (8.1, 8.3)].

ADVERSE REACTIONS

Adverse Reactions - The most common adverse reactions (?10%) that occurred more frequently in the ERLEADA-treated patients (? 2% over placebo) from the randomized placebo-controlled clinical trials (TITAN and SPARTAN) were fatigue, arthralgia, rash, decreased appetite, fall, weight decreased, hypertension, hot flush, diarrhea and fracture.

Laboratory Abnormalities - All Grades (Grade 3-4)

Hematology - In the TITAN study: white blood cell decreased ERLEADA 27% (0.4%), placebo 19% (0.6%). In the SPARTAN study: anemia ERLEADA 70% (0.4%), placebo 64% (0.5%); leukopenia ERLEADA 47% (0.3%), placebo 29% (0%); lymphopenia ERLEADA 41% (2%), placebo 21% (2%)

Chemistry - In the TITAN study: hypertriglyceridemia ERLEADA 17% (3%), placebo 12% (2%). In the SPARTAN study: hypercholesterolemia ERLEADA 76% (0.1%), placebo 46% (0%); hyperglycemia ERLEADA 70% (2%), placebo 59% (1%); hypertriglyceridemia ERLEADA 67% (2%), placebo 49% (0.8%); hyperkalemia ERLEADA 32% (2%), placebo 22% (0.5%)

Rash - In 2 randomized studies, rash was most commonly described as macular or maculopapular. Adverse reactions of rash were 26% with ERLEADA vs 8% with placebo. Grade 3 rashes (defined as covering >30% body surface area [BSA]) were reported with ERLEADA treatment (6%) vs placebo (0.5%).

The onset of rash occurred at a median of 83 days. Rash resolved in 78% of patients within a median of 78 days from onset of rash. Rash was commonly managed with oral antihistamines, topical corticosteroids, and 19% of patients received systemic corticosteroids. Dose reduction or dose interruption occurred in 14% and 28% of patients, respectively. Of the patients who had dose interruption, 59% experienced recurrence of rash upon reintroduction of ERLEADA.

Hypothyroidism - In 2 randomized studies (SPARTAN and TITAN), hypothyroidism was reported for 8% of patients treated with ERLEADA and 2% of patients treated with placebo based on assessments of thyroid-stimulating hormone (TSH) every 4 months. Elevated TSH occurred in 25% of patients treated with ERLEADA and 7% of patients treated with placebo. The median onset was at the first scheduled assessment. There were no Grade 3 or 4 adverse reactions. Thyroid replacement therapy, when clinically indicated, should be initiated or dose-adjusted.

DRUG INTERACTIONS

Effect of Other Drugs on ERLEADA - Co-administration of a strong CYP2C8 or CYP3A4 inhibitor is predicted to increase the steady-state exposure of the active moieties. No initial dose adjustment is necessary; however, reduce the ERLEADA dose based on tolerability [see Dosage and Administration (2.2)].

Effect of ERLEADA on Other Drugs

CYP3A4, CYP2C9, CYP2C19, and UGT Substrates - ERLEADA is a strong inducer of CYP3A4 and CYP2C19, and a weak inducer of CYP2C9 in humans. Concomitant use of ERLEADA with medications that are primarily metabolized by CYP3A4, CYP2C19, or CYP2C9 can result in lower exposure to these medications. Substitution for these medications is recommended when possible or evaluate for loss of activity if medication is continued. Concomitant administration of ERLEADA with medications that are substrates of UDP-glucuronosyl transferase (UGT) can result in decreased exposure. Use caution if substrates of UGT must be co-administered with ERLEADA and evaluate for loss of activity.

P-gp, BCRP or OATP1B1 Substrates - Apalutamide is a weak inducer of P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and organic anion transporting polypeptide 1B1 (OATP1B1) clinically. Concomitant use of ERLEADA with medications that are substrates of P-gp, BCRP, or OATP1B1 can result in lower exposure of these medications. Use caution if substrates of P-gp, BCRP or OATP1B1 must be co-administered with ERLEADA and evaluate for loss of activity if medication is continued.
