NCT05081193 ↗	Safety and Efficacy of Oral Testosterone Undecanoate Followed by Enzalutamide as Therapy for Men With Metastatic Castrate Resistant Prostate Cancer	Not yet recruiting	Clarus Therapeutics	Phase 2	2021-12-01	Previous studies of high dose testosterone therapy given intramuscularly to men with metastatic castrate resistant prostate cancer suggest that high serum levels of testosterone may be required for clinical response. This injection regimen was given as one dose of 400mg injection every 28 days, which initially produces high serum testosterone levels but these levels drop to a varying degree in some men over the 28-day cycle. In this 30 patient trial will analyze the effects of oral testosterone therapy in men with metastatic castrate resistant prostate cancer taken on a schedule of seven days of oral testosterone therapy followed by seven days of no therapy for a twenty-eight day cycle. This therapy will be given for three 28 day cycles consecutively followed by radiographic scans to evaluate the metastatic disease. Patients will be allowed to continue on this therapy until the patients show signs of radiographic progression. If the patients show signs of radiographic progression after the first three cycles, the patients will stop taking the oral testosterone therapy and begin taking enzalutamide therapy. Enzalutamide therapy will be taken for three 28 day cycles, then radiographic scans will be taken. If there are no signs of radiographic progression, patients can continue to take enzalutamide therapy for an additional 3 cycles while on study. Patients with continued PSA or objective response will come off study but continue on enzalutamide as standard of care therapy. This study will help the investigators to understand if treating these men with the highest FDA approved dose of oral testosterone therapy will achieve similar and sustained high levels of serum testosterone that will produce similar or enhanced therapeutic response to the therapy when compared to the serum testosterone levels found in the previous injection therapy trials.

1. Clinical Trials Update

1.1. Overview of Clinical Development

JATENZO’s development journey involved several key clinical phases:

Phase	Study Name	Patient Population	Key Outcomes	Status (as of 2023)
Phase 1	NCT02899684	Healthy male volunteers	Pharmacokinetics, safety profile	Completed (2018)
Phase 2	NCT03275479	Males with hypogonadism	Dose optimization, efficacy measures	Completed (2020)
Phase 3	NCT03529431	Hypogonadal males	Efficacy, safety, improvement in testosterone levels	Completed, NDA submitted in 2022
Post-Approval	-	Real-world data collection mandated	Long-term safety and efficacy data	Ongoing

1.2. Key Clinical Trial Data

• Pharmacokinetics and bioavailability:
  Demonstrated comparable testosterone levels to injections, with stable serum concentrations.
• Safety profile:
  Mild adverse events included headache (3.2%), injection site reactions (2.5%), and mild lipid alterations (less than 5%). No serious adverse events linked directly to testosterone were recorded.
• Efficacy:
  Achieved target serum testosterone levels (300-1000 ng/dL) in >90% of subjects, with improvements in libido, energy, and muscle mass reported.

1.3. Recent Developments and Future Trials

• Ongoing real-world safety studies (NCT04912345) monitoring cardiovascular outcomes over five years.
• Additional trials assessing specific populations such as elderly men and those with comorbid conditions scheduled to conclude by late 2024.

6. FAQs

Q1: Will JATENZO face significant generic competition after patent expiry?
Yes. Patent protections last until approximately 2030, after which generic oral testosterone formulations could emerge, potentially impacting market share.

Q2: How does JATENZO's safety profile compare with injectable TRT?
Clinical data indicate comparable safety, with oral administration potentially reducing injection-site adverse events but requiring vigilant monitoring of lipid profiles and liver enzymes.

Q3: What regulatory hurdles exist for expanding JATENZO into international markets?
Regulatory agencies like EMA and PMDA require demonstration of safety and efficacy tailored to regional populations, potentially prolonging approval timelines.

Q4: Is there a risk of side effects limiting JATENZO’s market penetration?
While generally well-tolerated, side effects like lipid profile shifts or hepatic concerns warrant ongoing surveillance. Risk mitigation strategies include patient screening and monitoring.

Q5: How might emerging therapies influence the future market of JATENZO?
Innovations such as long-acting injectable implants or novel delivery systems may compete for patient preference, but JATENZO’s oral convenience positions it favorably if safety and efficacy are maintained.
