ZT-031 is a cyclic 31-amino acid analog of parathyroid hormone (PTH) that is in development by Zelos Therapeutics Inc for the treatment of osteoporosis and other bone-related disorders. ZT-031 activates the PTH type 1 receptor - the molecular target of the currently marketed osteogenic peptides PTH and PTH(1-34). Daily subcutaneous injections of ZT-031 prevented bone loss and replaced bone that had already been lost in an ovariectomized rat model of osteoporosis. Daily subcutaneous injections of ZT-031 in gonad-intact monkeys increased bone mineral density (BMD) at cortical and cancellous bone sites and increased serum levels of bone formation markers. The daily subcutaneous administration of ZT-031 to postmenopausal women with osteoporosis elicited a dose-dependent increase in BMD of the lumbar spine, proximal femur and total hip area. Plasma levels of bone formation markers were significantly increased above baseline after 1 month of dosing, and prior to increases in bone resorption markers. ZT-031 was demonstrated to be safe and well tolerated; episodes of hypercalcemia were infrequent and observed with a frequency greater than with placebo only at the highest doses tested for the drug. Although available data are limited, the results obtained following treatment with ZT-031 have generally been at least as favorable as those obtained with other osteogenic PTH peptides. A novel dosing paradigm has been planned for the drug.

Background: Cardiac surgery patients are at increased risk for venous thromboembolism (VTE). Prevention is the most critical strategy to reduce VTE-associated morbidity and death. However, there is a lack of data on the optimal approach to VTE prophylaxis in this population of high-risk patients.

Objective: Abaloparatide (ABL) is a synthetic parathyroid hormone-related protein analog developed as an anabolic drug to treat osteoporosis. ABL increases bone mineral density (BMD) of the long bones and spine; however, the influence of ABL on alveolar bone regeneration remains unknown. This study assessed the effects of systemic ABL administration on tooth extraction socket healing and dental implant osseointegration in a preclinical rodent model.

Buprenorphine has superior safety in opioid use disorder compared with alternatives due to its action as a partial opioid agonist, which limits its ability to cause respiratory depression. There is a risk of precipitated opioid withdrawal after buprenorphine exposure in someone using full opioid agonists. Buprenorphine induction strategies that avoid precipitated withdrawal remain a crucial component for starting buprenorphine in individuals actively using opioids.

Introduction: Motor recovery following nerve injury is dependent on time required for muscle reinnervation. This process is imperfect, however, and recovery is often incomplete. At the neuromuscular junction (NMJ), macrophage signaling aids muscle reinnervation.

Introduction: Understanding predictors of smoking cessation medication efficacy facilitates the ability to enhance treatment effectiveness. In our pilot trial, exenatide, a glucagon-like peptide-1 receptor agonist, adjunct to nicotine patch improved smoking abstinence compared to nicotine patch alone. This secondary analysis explores potential baseline characteristics associated with differential treatment response to exenatide.
