Mechanism of Action: Understanding VMAT2 Inhibition#
NBI-1140675 is an oral, selective second-generation small molecule inhibitor of the vesicular monoamine transporter 2 (VMAT2). VMAT2 regulates dopamine, serotonin, norepinephrine, and histamine levels in the brain. By inhibiting VMAT2, NBI-1140675 can modulate neurotransmitter release, potentially alleviating symptoms of various neurological and neuropsychiatric disorders. The selective nature of NBI-1140675 aims to minimize off-target effects, potentially improving tolerability compared to first-generation VMAT2 inhibitors.
Phase 1 Trial: Safety, Tolerability, and Pharmacokinetics#
The primary objective of the Phase 1 clinical study is to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of NBI-1140675 in healthy adult participants. PK measures how the body absorbs, distributes, metabolizes, and excretes the drug, while PD assesses the drug's effects on the body. Key endpoints include monitoring adverse events, measuring drug concentrations in the blood, and evaluating changes in relevant biomarkers. The results of this trial will inform future development decisions and help determine the optimal dosing regimen for subsequent clinical studies.

Share Repurchase: A Vote of Confidence or Financial Maneuvering?#
Share Repurchase: A Vote of Confidence or Financial Maneuvering?#
NBIX's Board of Directors authorized a $500 million share repurchase program in February 2025, in addition to a completed $300 million accelerated repurchase program (completed in early February 2025). Share repurchase programs can impact EPS by reducing the number of outstanding shares and can affect ROE by increasing financial leverage. The actual impact on EPS and ROE depends on the repurchase price, the number of shares repurchased, and the company's financial performance. Share repurchases can be viewed as a signal of management's confidence in the company's future prospects. By reducing the number of outstanding shares, the company can increase EPS, making the stock more attractive to investors. However, share repurchases can also be seen as a way to artificially inflate EPS and ROE, particularly if the company is not generating sufficient organic growth.
EPS and ROE Impact: Quantifying the Benefits of Share Repurchase#
Share repurchases reduce the number of outstanding shares, which can lead to an increase in EPS. The magnitude of the impact depends on the number of shares repurchased and the company's net income. For example, if NBIX repurchases $500 million worth of shares at an average price of $113 per share, it would reduce the number of outstanding shares by approximately 4.4 million. This reduction in shares outstanding would increase EPS, assuming the company's net income remains constant. However, the actual impact on EPS will depend on the company's financial performance and the repurchase price.
