Summary for Patent: 10,028,995

Title:	Angiotensin II alone or in combination for the treatment of hypotension
Abstract:	The present invention relates, inter alia, to a method comprising administering to a subject having high output shock and undergoing treatment with a catecholamine at a dose equivalent to at least about 0.2 mcg/kg/min of norepinephrine a dose of angiotensin II which is effective to raise the blood pressure of the subject to a mean arterial pressure (MAP) of about 65 mm or above, and which is effective to reduce the dose of the catecholamine required to maintain a MAP of about 65 mm to the equivalent of about 0.05-0.2 mcg/kg/min norepinephrine or less, or to the equivalent of about 0.05 mcg/kg/min norepinephrine or less.

Deep Dive: Claims Analysis & Strategic Considerations

Scope of Chemical Structure Claims

• The core structure is defined with variable substituents, broadening the scope but requiring support for each embodiment.

• Claim dependencies narrow scope, e.g., specific substituents in positions X, Y, Z.

Method of Use Claims

• Claim language emphasizes treatment of specific diseases, with potential for exclusivity in these indications.

• Off-label use remains unpatented; focus is on method-specific claims.

Potential Challenges & Workarounds

• Prior art challenges targeting similar core structures with different substitutions.

• Design-around strategies: modifying substituents to avoid overlap while maintaining activity.
