Abstract Most widely used testosterone replacement therapy (TRT) products can be inconvenient and cumbersome topical and invasive injectable requiring dose adjustments to attain efficacy. In a pivotal study, a recently approved oral TRT only 26% of patients did not require any dose adjustment. Typically, patients start on a sub-therapeutic dose with gradual dose increases to attain efficacy resulting in additional visit(s) to clinic and pharmacy. Physician research data (N=402) suggested it typically takes 3-6 months of titrations to reach an efficacious dose for majority of patients, a significant barrier in effecting a switch without a period of “efficacy gap”. The requirement of additional visit(s) presents significant challenges for new and current patients desiring to start and to switch to a convenient TRT option, especially in the current COVID-19 pandemic. Recent reports suggest increase of disease severity/mortality in men with low testosterone is possibly due to underlying co-morbidities commonly associated with male hypogonadism. There remains a need for an effective, safe, and easy to use and prescribe product that does not require dose titration. TLANDO is a “triglyceride-free” oral single strength TRT with single dose designed to lymphatically deliver effective and safe levels of testosterone regardless of meal fat content. Moreover, dose titration is prone to some inherent titration decision errors and requires understanding of often complex titration rules. The objective is to assess whether TLANDO, an oral TRT without requiring dose titration, safely restores effective testosterone (T) levels in hypogonadal men. An open-label, single-arm, multicenter study (NCT03242590) was performed with TLANDO in hypogonadal males (N=95). Subjects received orally 225 mg twice a day testosterone undecanoate (TU) for 24 days without dose adjustment. Efficacy was evaluated by % of subjects who achieved daily T Cavg within the eugonadal range. Using 450mg daily dose without dose adjustment, 80% of subjects (95% CI of 72% to 88%) achieved a T Cavg in the normal range and safely restored with mean T Cavg of 476±184 ng/dL post steady state. T restoration was comparable to other non-oral TRT products. TLANDO was well tolerated with no deaths, no drug-related severe AEs, and no hepatic AEs. In conclusion, effective T restoration using TLANDO, an easy to use and prescribe oral TRT option, was confirmed. Minimal AEs were reported with no hepatic AEs. Upon approval, TLANDO will be the first convenient TRT option without requiring dose adjustments; therefore, enabling selection of an efficacious dose from the start of therapy. TLANDO is well suited for new or existing TRT patients desiring a convenient oral option.

Abstract Male hypogonadism is characterized by symptoms and deficiency (<300 ng/dL) in levels of in total testosterone (TT), a critical hormone for sexual, cognitive, and body function and development. TLANDO, a testosterone undecanoate (TU) comprising lymphatically delivered oral testosterone replacement therapy (TRT) option not requiring dose titration, treatment has demonstrated effective restoration in hypogonadal men of TT levels to the eugonadal range in multiple clinical studies. TLANDO therapy resulted in decreased sex hormone binding globulin with increased free testosterone (FT). TLANDO’s unique delivery system enables consistent restoration of TT regardless of meal fat content. Moreover, TLANDO has shown potential to improve liver health through resolution of fatty liver disease in hypogonadal men and is not known to have any adverse liver effects. However, it is unclear if fixed dose TLANDO therapy without dose adjustment improves symptoms of psychosexual functions. The objective is to assess key sexual and mental domain Patient Reported Outcomes (PRO) post 52 weeks of treatment using TLANDO on the to-be-marketed dosing regimen in comparison with a widely used topical TRT, Androgel 1.62%. Data analysis was performed in in hypogonadal males post TLANDO treatment without dose adjustment, and in patients on the active control from a randomized, multi-center, open label, active controlled 52-week trial (SOAR, NCT02081300). Sexual and mental domain function PROs were measured at baseline (BL) and end of study (EOS) using Psychosexual Daily Questionnaire (PDQ) and Short Form (SF)-36 surveys and compared between TLANDO and active control. Post treatment with TLANDO dosing regimen not requiring dose titration, key sexual domain function PROs at week 52 were significantly (p<0.05) improved from BL: positive mood (BL:4.5 vs EOS:5.1, p<0.001), negative mood (1.8 vs 1.4, p<0.01), overall sexual desire (2.5 vs 3.7, p<0.001), sexual activity (2.5 vs 4.0, p<0.001), highest pleasure with partner (2.0 vs 2.8, p=0.06), highest pleasure without partner (1.8 vs 2.4, p<0.05), weekly maintained erection (3.3 vs 4.5, p<0.001), and weekly full erection % (50.5% vs 68.9%, p<0.001). Most sexual and mental function PROs were comparable to Androgel 1.62. TLANDO therapy was well tolerated through 52 weeks of treatment exposure. In conclusion, TLANDO, a novel easy to use and prescribe TRT not requiring dose titration, demonstrated improvement in sexual and mental PROs, a significant unmet need in hypogonadal males. Further placebo-controlled studies are warranted to better elucidate these improvements.

Abstract Introduction and Objective: A new, first-in-class oral testosterone (T) replacement therapy product [T-undecanoate (TU) capsules] was recently approved by FDA to treat hypogonadal men. Clinical trials were conducted to evaluate, in part, the impact of oral TU therapy on important secondary efficacy endpoints: Psychosexual and/or general well-being (Trial I and II); and body composition and bone mineral density (BMD) (Trial II). Subject and Methods: Hypogonadal men (AM serum T ≤ 300 ng/dL) age 18 to 65 (Trial I) or 75 years old (Trial II) were randomized into open-label, active-comparator (T-gel/solution) trials. Subjects received: Trial 1: Oral TU (n=166) or a topical T solution (n=55) for 4-6 mos.; or Trial II: Oral TU (n=162) or T-gel (n=163) for 12 mos. The starting oral TU dose (with food) was 237 mg, BID in Trial I and 316 mg, BID in Trial II; up to 2 dose-titration opportunities were available to achieve eugonadal T concentrations (assayed by LC-MS/MS). In Trial I, Psychosexual Daily Questionnaires (PDQ) were completed by study subjects for 7 days at baseline and prior to final clinic visit (Day 105-180). In Trial II, the SF-36 well-being questionnaire was completed on Days 0, 30, 90, 180, 270 and 365 and PDQs were completed for 7 days prior to clinic visits on these same days. In Trial II body composition and BMD was assessed by DEXA scan on Days 0, 180 and 365. Safety was monitored by physical exam and standard clinical lab tests. Results: Mean serum T in response to oral TU was 489 ± 155 ng/dL (mean ± SD) (Trial I) and 628 ± 342 ng/dL (Trial II); 84% of subjects in each trial achieved mean T concentrations in the eugonadal range. Statistically significant mean changes from baseline (p<0.0001) for most SF-36 well-being parameters were observed in both oral TU and T-gel groups. Psychosexual questionnaire results also demonstrated statistically significant improvement over baseline (p<0.0001) in most parameters at Day 30 and all timepoints thereafter in both trials. On Days 180 and 365 (v. baseline) oral TU was associated with a significant reduction in fat mass [-1.92 ± 2.79 (SD) and -2.4 ± 3.6 kg, respectively] (p<0.0001) and an increase in lean body mass [+2.87 ± 2.73 and +3.15 ± 2.69 kg, respectively] (p<0.0001). Oral TU increased mean BMD over baseline on Days 180 and 365 in spine [+0.013 ± 0.035 and +0.018 ± 0.042 g/cm2, respectively (p<0.0001)] and hip [+0.006 ± 0.019 and +0.012 ± 0.023 g/cm2, respectively (p<0.0001)]. Oral TU exhibited a safety profile consistent with commonly prescribed topical T-comparators. Modest increases in cuff sBP of 2.8 ± 11.84 (SD) mm Hg and 1.8 ± 10.76 mm Hg were observed in Trial I for both oral TU and the comparator T-solution. Conclusions: Treatment of hypogonadal men with oral TU yielded circulating mean T concentrations in the mid-eugonadal range and significantly improved psychosexual, general well-being, body composition and BMD parameters comparable to transdermal T administration.

Objective: To define the optimized inter-injection interval of injectable testosterone undecanoate (TU) treatment for hypogonadal and transmen based on individual dose titration in routine clinical practice. Design and Methods: Prolective observational study of consecutive TU injections in men undergoing testosterone replacement therapy for pathological hypogonadism or masculinization of female-to-male transgender (transmen) subject to individual dosing titration to achieve a stable replacement regimen. Results: From 2006 to 2019, 6899 injections were given to 325 consecutive patients. After excluding the 6-week loading dose, 6300 injections were given to 297 patients who had at least three and a median of 14 injections. The optimal injection interval (mean of last three injection intervals), had a median of 12.0 weeks (interquartile range 10.4–12.7 weeks). The interval was significantly influenced by age and body size (body surface area, BSA) but not by diagnosis or trough serum LH, FSH and SHBG. Longer (≥14 weeks; 68/297, 23%), but not shorter (≤10 weeks; 22/297, 7.4%), intervals were weakly correlated with age but not diagnosis or other covariables. Low blood hemoglobin increased with trough serum testosterone to reach plateau once testosterone was about 10 nmol/L or higher. Conclusion: Optimal intervals between TU injection after individual titration resulted in the approved 12-week interval in 70% of patients with only minor influence for clinical application of age and body size (BSA) and not of trough serum LH, FSH and SHBG. Individually optimised inter-injection interval did not differ between men with primary or secondary hypogonadism or transmen.

In men with sexual dysfunction due to hypogonadism, plasma testosterone is by definition low; testosterone replacement therapy may help to overcome impotence and loss of libido, but not infertility. Oral administration of the natural hormone is inefficient because testosterone, like some other natural steroids, is rapidly inactivated in the gut wall and liver. Sublingual administration allows direct absorption into the systemic circulation, but frequent dosing is needed. Testosterone is therefore usually given in the UK as an ester by intramuscular injection every 2 – 4 weeks, or by surgical insertion of an implant every 3 – 6 months with risk of extrusion1, infection or haematoma formation.2 An oral preparation which raised plasma testosterone predictably when given by mouth would therefore represent a significant therapeutic advance. This is what Restandol (Organon) - testosterone undecanoate dissolved in oleic acid - is claimed to offer.

Abstract Context A novel formulation of oral testosterone (T) undecanoate (TU) was evaluated in a phase 3 clinical trial. Objective Determine efficacy, short-term safety, and alignment of new oral TU formulation with current US approval standards for T replacement therapy. Design Randomized, active-controlled, open-label study. Setting and Patients Academic and private clinical practice sites; enrolled patients were clinically hypogonadal men 18 to 65 years old. Methods Patients were randomized 3:1 to oral TU, as prescribed (JATENZO®; n = 166) or a topical T product once daily (Axiron®; n = 56) for 3 to 4 months. Dose titration was based on average T levels (Cavg) calculated from serial pharmacokinetic (PK) samples. T was assayed by liquid chromatography–mass spectrometry/mass spectrometry. Patients had 2 dose adjustment opportunities prior to final PK visit. Safety was assessed by standard clinical measures, including ambulatory blood pressure (BP). Results 87% of patients in both groups achieved mean T Cavg in the eugonadal range. Sodium fluoride-ethylenediamine tetra-acetate plasma T Cavg (mean ± standard deviation) for the oral TU group was 403 ± 128 ng/dL (~14 ± 4 nmol/L); serum T equivalent, ~489 ± 155 ng/dL (17 ± 5 nmol/L); and topical T, 391 ± 140 ng/dL (~14 ± 5 nmol/L). Modeling/simulation of T PK data demonstrated that dose titration based on a single blood sample 4 to 6 h after oral TU dose yielded efficacy (93%) equivalent to Cavg-based titration (87%). Safety profiles were similar in both groups, but oral TU was associated with a mean increase in systolic BP of 3 to 5 mm Hg. Conclusion A new oral TU formulation effectively restored T to mid-eugonadal levels in hypogonadal patients.

Abstract Introduction: An oral testosterone (T) replacement therapy (TRT) would be the preferred choice for many hypogonadal men. Until recently, the only oral TRT approved in the US was methyl-T which has been associated with hepatotoxicity. The safety of a novel oral T undecanoate (TU) formulation was evaluated in hypogonadal men for up to 2 years. Subjects and Methods: Two open-label, multicenter, dose-titration trials were conducted in hypogonadal men (serum T ≤ 300 ng/dL) age 18-75 years. Trial I was a randomized, active-controlled, 2-arm, 12-month study. Trial 2 was a long-term extension of those who completed Trial 1. Statistical analyses were only conducted with the subjects who completed Trial 1 and continued treatment in Trial 2, thus providing up to 2 full years of data. Safety was assessed by physical exam, AE reporting, and routine clinical laboratory measurements. Results: Overall, up to 81 subjects were available for evaluation. T concentration increased from 208.3 ± 102.4 ng/dL (Mean ± SD) at baseline (BL) to 470.1 ± 396.5 ng/dL after 24 Mo of therapy with oral TU, and 84% of men achieved T in eugonadal range (300-1000 ng/dL) after 90 days of therapy. Mean T concentrations remained in the eugonadal range throughout Trial 2. There were no clinically significant changes in liver function tests - ALT (28.0 ± 12.3 to 26.6 ± 12.8 U/L), AST (21.8 ± 6.8 to 22.0 ± 8.2 U/L), and bilirubin (0.58 ± 0.22 to 0.52 ± 0.19 mg/dL) throughout the two studies. At Day 270, one subject had an ALT level of 227 U/L, which was > 4x the ULN (ULN for ALT = 45 U/L). Despite continued use of oral TU, ALT was measured again on Day 290, and the level dropped to 87 U/L, < 2x ULN. This was the only instance of an LFT elevation. There was a modest initial increase in prostate-related growth endpoints (i.e. PSA and prostate volume) that stabilized over time. There were not any significant changes in IPSS total score (-0.06 ± 3.9 vs BL). There were significant, yet modest, increases in mean HCT (+2.52 ± 3.7% vs BL, p < 0.001) and cuff systolic BP (+5.6 ± 15.0 mmHg vs BL, p = 0.006). The change in prostate-related growth variables and CV endpoints changed initially and stabilized throughout the 2 trials. For example, systolic BP consistently showed a mean increase from BL between 3 - 6 mmHg. Conclusion: This oral TU formulation is an effective long-term therapy for hypogonadal men and has a safety profile consistent with other approved T products. Notably, no evidence of liver toxicity was observed. The long-term efficacy and safety profile of oral TU may provide a treatment option that avoids issues associated with other TRTs, such as injection site pain or transference to partners and children.

Abstract Objective To illustrate the importance of treatment duration with intramuscular testosterone undecanoate (Nebido®) for the final spermatogenesis recovery after treatment cessation. Also, to show a subsequent poor efficacy of the selective estrogen receptor modulator (SERM) clomiphene citrate (CC) in treating steroid-induced azoospermia following Nebido® cessation and describe that initial oligozoospermia, existing before starting Nebido®, largely contributes to that treatment outcome. Methodology Setting: Department of Human Reproduction and Department of Endocrinology, Clinical Hospital Center Rijeka, Rijeka, and Department of Endocrinology, Clinical Hospital Center Sestre milosrdnice, Zagreb, Croatia. Patient: A male patient having been diagnosed with primary hypogonadotropic hypogonadism, oligozoospermia and low testosterone (T) level, was treated with intramuscular testosterone undecanoate (TU) depot 1 g (Nebido®) to prevent further progression of testosterone deficiency symptoms (low mood, energy and concentration, fatigue, muscle weakness). Interventions: Stopping Nebido® and treatment with CC 50 mg per day 5 days per week for 3–6 month to recover spermatogenesis. Main outcome measures: T levels and semen analyses. Results Semen analyses did not return to values before taking Nebido® 1 year after cessation nor after 3 months of treatment with CC. Values of T, follicle stimulating hormone (FSH) and luteinizing hormone (LH) dropped even more than before starting Nebido®, after 1 year of cessation. Conclusions Here we describe a case of initially idiopathic gonadal failure with subsequent secondary gonadal failure and infertility resulting from testosterone replacement therapy (TRT) treatment, and poor spermatogenesis recovery outcome of CC used post Nebido® cessation.

Purpose: The purpose of this drug review was to explore the safety and efficacy of the newly approved benzodiazepine, remimazolam, in order to evaluate its place in therapy. Summary: Remimazolam has a faster onset of action and recovery time than midazolam when given as single IV doses. Additionally, it has no known CYP450 interactions that would contribute to drug-drug interactions. Patients with severe hepatic impairment may require dose titration as well as the elderly who should be closely monitored. Although remimazolam vials should be protected from light and must be reconstituted immediately before use, the reconstituted vial may be stored for later use at room temperature for up to 8 hours. Remimazolam is more expensive than current options used in practice, as such individual institutional formulary and provider preference will require review to see if its advantages are worth the additional cost and to determine its place in therapy. Conclusion: Remimazolam is a novel option when choosing a benzodiazepine for procedural sedation that has pharmacokinetic and pharmacodynamic advantages when compared to other commonly prescribed sedatives. Remimazolam has proved superior to midazolam when analyzing drug-drug interactions, onset, and time to alertness. Remimazolam also has a shorter elimination half-life and decreased volume of distribution when compared to midazolam.

IntroductionThe PIONEER 7 trial demonstrated superior glycemic control and weight loss with once-daily oral semaglutide with flexible dose adjustment versus sitagliptin 100 mg in type 2 diabetes. This 52-week extension evaluated long-term oral semaglutide treatment and switching from sitagliptin to oral semaglutide.Research design and methodsA 52-week, open-label extension commenced after the 52-week main phase. Patients on oral semaglutide in the main phase continued treatment (n=184; durability part); those on sitagliptin were rerandomized to continued sitagliptin (n=98) or oral semaglutide (n=100; initiated at 3 mg) (switch part). Oral semaglutide was dose-adjusted (3, 7, or 14 mg) every 8 weeks based on glycated hemoglobin (HbA1c) (target <7.0% (<53 mmol/mol)) and tolerability. Secondary endpoints (no primary) included changes in HbA1c and body weight.ResultsIn the durability part, mean (SD) changes in HbA1c and body weight from week 0 were –1.5% (0.8) and –1.3% (1.0) and –2.8 kg (3.8) and –3.7 kg (5.2) at weeks 52 and 104, respectively. In the switch part, mean changes in HbA1c from week 52 to week 104 were –0.2% for oral semaglutide and 0.1% for sitagliptin (difference –0.3% (95% CI –0.6 to 0.0); p=0.0791 (superiority not confirmed)). More patients achieved HbA1c <7.0% with oral semaglutide (52.6%) than sitagliptin (28.6%; p=0.0011) and fewer received rescue medication (9% vs 23.5%). Respective mean changes in body weight were –2.4 kg and –0.9 kg (difference –1.5 kg (95% CI –2.8 to –0.1); p=0.0321). Gastrointestinal adverse events were the most commonly reported with oral semaglutide.ConclusionsLong-term oral semaglutide with flexible dose adjustment maintained HbA1c reductions, with additional body weight reductions, and was well tolerated. Switching from sitagliptin to flexibly dosed oral semaglutide maintained HbA1c reductions, helped more patients achieve HbA1c targets with less use of additional glucose-lowering medication, and offers the potential for additional reductions in body weight.Trial registration numberNCT02849080.
