Contrary to the common assumption that provider-administered injections ensure superior adherence, real-world data suggests patients on oral ADT (relugolix) are just as, if not more, adherent. This challenges the notion that oral therapies are inherently less reliable for long-term treatment in prostate cancer.

For the typically young and active desmoid tumor patient population, the convenience of a once-daily oral pill is a major advantage. This seemingly simple feature significantly improves compliance and adherence compared to twice-daily regimens, making it a key factor in real-world treatment feasibility and success, more so than the specific milligram dosage.

While the gut instinct is that patients prefer daily pills over injections, this preference flips when the injection is highly infrequent. For chronic conditions, a quarterly shot (four per year) is often viewed as more convenient and favorable by patients than the burden of a daily oral medication, challenging conventional wisdom on administration routes.

Contrary to concerns about compliance with daily oral medication, real-world retrospective studies show patients demonstrate higher persistence and adherence to oral relugolix compared to traditional injectable GnRH agonists and antagonists for prostate cancer, challenging clinical biases.

The EMBARK trial showed that enzalutamide monotherapy was superior to standard ADT monotherapy for metastasis-free survival. This suggests potent AR antagonism may be a more effective strategy than simply depleting the testosterone ligand, challenging the long-held dogma of ADT being the fundamental building block for systemic prostate cancer therapy.

Apogee positions its 3- and 6-month dosing as a driver of superior adherence and better long-term outcomes, not just a lifestyle perk. The CEO draws a parallel to the psoriasis market, where less frequent dosing transformed the therapeutic landscape by encouraging more patients to start and stay on therapy.

The oral GnRH antagonist Relagolix allows for much quicker testosterone recovery (1-2 months vs. 3-6 for leuprolide). While beneficial in curative-intent settings, this rapid recovery is a double-edged sword that could shorten the "off-therapy" period during intermittent treatment for metastatic disease.

New drug formulations, like those for HIV prevention or cholesterol, create an internal depot that releases medicine over months. This dramatically improves efficacy by solving the massive problem of patient non-adherence to daily pills, representing a major shift in managing chronic conditions.

The oral antagonist relugolix allows for rapid testosterone recovery after discontinuation. While useful for planned intermittent therapy, a case study shows this can be a clinical pitfall. In non-adherent patients who self-discontinue, it can lead to an equally rapid rise in PSA and disease progression.

A VA study using real-world data confirms that androgen receptor pathway inhibitors (ARPIs) combined with ADT significantly improve survival in elderly (>75), frail, and high-comorbidity prostate cancer patients. This evidence directly addresses clinician hesitancy to treat these vulnerable populations with standard-of-care combination therapy.

The IMbark trial demonstrated that an ARPI (enzalutamide), either alone or with ADT, outperformed ADT monotherapy in high-risk patients. This pivotal finding raises the question of whether giving ADT alone in any setting, such as with radiation for localized disease, is now an outdated and inferior approach.
