Data Show Tesamorelin May Reduce CVD Risk by Reducing EVAFMONTREAL, Oct. 17, 2024 (GLOBE NEWSWIRE) -- Theratechnologies Inc. (“Theratechnologies” or the “Company”) (TSX: TH) (NASDAQ: THTX), a biopharmaceutical company focused on development and commercialization of innovative therapies, today announced data from two poster presentations, focusing on the association between excess visceral abdominal fat (EVAF) and cardiovascular disease (CVD) risk in people with HIV (PWH), and on the use of tesamorelin to reduce such risk. In a poster presentation at IDWeek 2024 in Los Angeles, Calif., investigators from the Visceral Adiposity Measurement and Observations Study (VAMOS) reported that EVAF is one of several risk factors that contribute to heightened CVD risk in PWH who are on modern anti-retroviral therapy (ART) regimens. In a separate poster presentation, researchers demonstrated that the EVAF-lowering properties of tesamorelin, a growth hormone-releasing factor (GHRF), enable a reduction in CVD risk in PWH. “The two studies presented at IDWeek 2024 suggest that excess visceral abdominal fat is an overlooked risk factor for cardiovascular disease in people with HIV, and that use of tesamorelin for visceral abdominal fat reduction may contribute to lowering cardiovascular disease risk,” said Christian Marsolais, Ph.D., Senior Vice President and Chief Medical Officer of Theratechnologies. “We hope greater awareness of EVAF, and of strategies to address this risk factor, lead to improved outcomes in people with HIV being treated with ART medicines.” VAMOS Data VAMOS, a cross-sectional, multicenter observational study, is the first trial designed to improve the understanding of the impact of EVAF on CVD, steatotic liver disease, insulin resistance, and other metabolic parameters in PWH who are on modern ART regimens. The investigators examined the impact of EVAF (defined as visceral fat surface area ≥130 cm2 by CT scan) on traditional CVD risk factors and overall cardiovascular (CV) risk in 170 participants with HIV. The prevalence of EVAF in the study was 58%, and the mean visceral fat area was 148 cm2. Among participants with EVAF, values for the Homeostatic Model Assessment for Insulin Resistance (HOMA-IR; p≤0.0001) and triglyceride:high-density lipoprotein (TG:HDL) ratios (p=0.0013) were higher than in those without EVAF. Investigators noted a positive correlation between EVAF and HOMA-IR (ρ=0.43, p≤0.0001) and TG:HDL ratios (ρ=0.33, p≤0.0001). Importantly, greater EVAF was associated with a higher 10-year atherosclerotic cardiovascular disease (ASCVD) risk (p≤0.0001). The investigators also found that increasing visceral fat surface area was inversely associated with growth hormone (GH) levels (ρ=-0.17, p=0.03), and that participants with EVAF had lower GH levels overall (p=0.05). “Excess visceral abdominal fat, or EVAF, is the key characteristic of central adiposity, a condition that is still prevalent in today’s population of people living with HIV, even among those who were never exposed to earlier anti-retroviral agents,” commented VAMOS investigator, John Koethe M.D., Associate Professor of Medicine at Vanderbilt University. “As the quantity of visceral fat rises, 10-year ASCVD risk scores increase, as well as traditional risk factors including insulin resistance and lipid levels. Together, these factors contribute to the heightened risk of cardiovascular disease we see in people with HIV, which is a particular concern among aging individuals. Additionally, the relationship we observed between EVAF and decreased growth hormone levels appears to support a focus on the growth hormone axis to impact EVAF.” Tesamorelin CV Risk Data Researchers examined data from two phase 3 randomized studies to assess the impact of tesamorelin-induced reduction of EVAF on CVD outcomes in 543 PWH. They calculated 10-year ASCVD risk scores for participants at baseline and at 26 weeks of tesamorelin treatment. The percentages of participants on lipid-lowering therapies, antihypertensive treatment, or diabetes medications were 44%, 37%, and 18%, respectively. Although most participants had low CVD risk at baseline, 44% had borderline to high CVD risk. Participants on tesamorelin tended toward a modest reduction in 10-year ASCVD risk scores, with an estimated change of -0.4% (95% confidence interval [CI] -0.89%, 0.05%). The reduction in CVD risk was relatively larger among subjects with higher CVD risk at baseline (p=0.038 for the overall trend among all participants). These reductions in ASCVD risk scores were driven primarily by reductions in total cholesterol, independent of lipid-lowering therapies. “Our analysis provides evidence that tesamorelin may contribute to a reduction in forecasted cardiovascular disease risk in persons with HIV, particularly among individuals at the highest baseline risk,” stated investigator Lindsay Fourman, M.D., Massachusetts General Hospital and Harvard Medical School. “Given the high prevalence of obesity and central adiposity in this population, a strategy that selectively reduces excess visceral abdominal fat may be particularly effective in CVD risk management.” IDWeek 2024, taking place October 16-19, is the joint annual meeting of the Infectious Diseases Society of America, the Society for Healthcare Epidemiology of America, the HIV Medicine Association, the Pediatric Infectious Diseases Society and the Society of Infectious Diseases Pharmacists.

AUSTIN, Texas, June 04, 2024 (GLOBE NEWSWIRE) -- Lumos Pharma, Inc. (NASDAQ:LUMO), a clinical-stage biopharmaceutical company focused on therapeutics for rare diseases, announced today details of new analyses of data from its Phase 2 OraGrowtH212 clinical trial presented in two posters at the 2024 Annual Meeting of the Endocrine Society (ENDO), held in Boston, MA, June 1-4, 2024. The posters were presented in parallel sessions on Monday June 3, 2024. “The new analyses of data from our OraGrowtH212 Trial further characterized LUM-201’s unique ability to augment the natural pulsatile secretion of growth hormone, producing comparable growth to injectable rhGH with significantly less exposure to circulating growth hormone,” said John C. McKew, PhD, President and Chief Scientific Officer of Lumos Pharma. “The presented results also provide additional support for our planned approach to a placebo-controlled Phase 3 trial of LUM-201 in moderate PGHD, a trial design proposed by the FDA as an appropriate option for oral LUM-201 given its differentiated mechanism as a growth hormone secretagogue.” In the poster MON-111, titled, Oral LUM-201 Restores Pulsatile Growth Hormone Secretion and Growth Response in Moderate Pediatric Growth Hormone Deficiency (PGHD): Key Discoveries from Phase 2 of OraGrowtH212 Trial (Cassorla, F, et al) [poster link], investigators evaluated growth hormone pulsatility data obtained at baseline and at six months following treatment with LUM-201. Results showed that at six months on LUM-201, a significant increase over baseline in key parameters was observed for the 1.6 mg/kg/day dose. At baseline GH secretion was 0.19 ±0.09 μg/kg/12-hrs; pulsatile GH was 1.17 ±0.66 μg/kg/12-hrs; and total GH was 1.35 ±0.66 μg/kg/12-hrs.At 6 months each parameter increased significantly: GH secretion to 0.36 ±0.21 μg/kg/12-hrs, pulsatile GH to 1.8 ±0.74 μg/kg/12-hrs, and total GH to 2.2 ±0.89 μg/kg/12-hrsA similar level of increase was observed in the 3.2 mg/kg/day dose cohortInvestigators combined data from both dose cohorts and conducted a deconvolution analysis on GH secretion. It was determined that at six months GH secretion was 3.3 ±1.8 to 4.4 ±2.1 μg/kg/day compared to 5.0 ±1.3 μg/kg/day derived from published data in normal children, indicating restoration of approximately normal GH secretion by LUM-201.Conclusion – at 6 months LUM-201 was able to restore endogenous GH pulsatile secretion to a similar level seen in normal children while also normalizing serum IGF-1 concentrations. Results indicate that by restoring endogenous GH secretion, LUM-201 facilitates growth utilizing a much lower amount of GH than that provided by daily exogenous rhGH. By providing an oral therapy that attains physiological GH profiles, investigational LUM-201 treatment aligns with the fundamental objectives of endocrine therapies, specifically the restoration of normal hormonal homeostasis. In a late-breaking poster (MON-704) titled, Growth Response to Oral Growth Hormone Secretagogue LUM-201 in Children with Moderate GH Deficiency (GHD) is Dependent on the Pattern of Pulsatile GH Secretion Stimulated by LUM-201 (Stevens, A, et al), [poster link], investigators evaluated pulsatile GH profiles and growth response to LUM-201. Data from OraGrowtH212 pulse assessments at Day 1 (D1) and at 6 months (M6) were analyzed utilizing a univariate Spearman’s rank correlations matrix to screen for relationships between D1 characteristics, D1 height velocity, 6M Annualized Height Velocity and interpulse, pulsatile, and total GH secretion at D1 and M6.The 12-hour pattern of pulsatile secretion was characterized using Functional Principal Component Analysis (FPCA) to identify dominant modes of variation in the functional data. Subjects were grouped into tertiles based on 6M AHV. The 12-hour profiles were grouped into three 4-hour intervals.Results: All parameters increased from D1 to M6D1 pulsatile GH secretion was positively associated with D1 AHVWhile 6M AHV increased compared to baseline, GH Secretion at D1 and M6 was not apparently correlated with 6M AHVIn the FPCA, difference in interquartile range (IQR) for mean GH secretion was highest in 0-4 hrs in subjects in the high and medium AHV tertiles, while subjects with low AHV at 6 months had the highest difference at 8-12 hours Conclusions – LUM-201 stimulates significant increases in GH secretion over 6 months in patients with moderate PGHD. The relationship between growth response and both the amount and pattern of pulsatile GH secretion, with the highest growth observed in OraGrowtH212 associated with greatest pulsatile activity early in the 12 hour profile. Restoring GH secretion with LUM-201 in moderate PGHD results in both an increase in the overall amount of GH, and importantly, an alteration of the pattern of the pulse profile, with distinct differences in these patterns between the best and lower responders.

Patients with growth hormone receptor deficiency, or Laron syndrome, appear to have lower than average risk factors for cardiovascular disease, according to a new study. A new study highlights possible cardiovascular health advantages in individuals with a rare condition known as growth hormone receptor deficiency (GHRD), also called Laron syndrome. GHRD, which is characterized by the body's impaired ability to use its own growth hormone and results in stunted growth, has been linked in mice to a record 40% longevity extension and lower risks for various age-related diseases. However, the risk of cardiovascular disease in individuals with GHRD has remained unclear until now, leading to the speculation that in people, this mouse longevity mutation may actually increase cardiovascular disease. The study, appearing in Med on April 26, 2024, is the latest product of an international collaboration spanning nearly 20 years between Valter Longo, professor of gerontology at the USC Leonard Davis School of Gerontology, and endocrinologist Jaime Guevara-Aguirre of the Universidad San Francisco de Quito, Ecuador. Over the past two decades, Longo, Guevara-Aguirre and colleagues have examined the health and aging of people with the gene mutation that causes GHRD. This rare mutation -- found in just 400 to 500 people worldwide -- was identified in a group of Ecuadorians whose ancestors had fled Spain during the Inquisition more than three centuries ago. The mutation leaves them with ineffective growth hormone receptors and results in a type of dwarfism. The team's previous research has indicated that while GHRD/Laron syndrome reduces growth, it also appears to reduce the risk of several age-related diseases. Although the Ecuadorians with GHRD have a higher rate of obesity, they have a very low risk of cancer and Type 2 diabetes. They also appear to have healthier brains and better performance on tests of cognition and memory. For the current study, the research team examined cardiovascular function, damage, and risk factors in GHRD subjects and their relatives. Researchers conducted two phases of measurements in Los Angeles and Ecuador, involving a total of 51 individuals, with 24 diagnosed with GHRD and 27 relatives without GHRD serving as controls. Key findings from the study included: "These findings suggest that individuals with GHRD have normal or improved levels of cardiovascular disease risk factors compared to their relatives," said Longo, senior author of the new study. "Although the population tested is small, together with studies in mice and other organisms this human data provide valuable insights into the health effects of growth hormone receptor deficiency and suggest that drugs or dietary interventions that cause similar effects could reduce disease incidence and possibly extend longevity." Along with co-corresponding authors Longo and Guevara-Aguirre, the study's coauthors included Amrendra Mishra and Priya Balasubramanian of USC; Carolina Guevara, Álvaro Villacres, Gabriela Peña, and Daniela Lescano of the Universidad San Francisco de Quito; Alexandra Guevara of the Instituto de Endocrinologia Metabolismo y Reproducción (IEMYR) in Quito; Marco Canepa of the University of Genova, Italy; and John Kopchick of Ohio University.
