Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company may be subject to various lawsuits, claims and other legal matters from time to time that arise in the ordinary course of conducting business. The Company records a liability when a particular contingency is probable and estimable. As of June 30, 2025, the Company was not party to any material legal proceedings and thus no contingent liabilities were recorded. Commitments During the year ended March 31, 2022, ISG entered into the PSA with Samsung to manufacture a certain quantity of batoclimab drug substance for, among other things, commercial sale, if approved. As of June 30, 2025, in connection with this agreement, the Company has a remaining minimum obligation to Samsung of approximately $43.1 million, of which $5.0 million, $10.1 million, $14.0 million and $14.0 million is expected to be paid during the remainder of the fiscal year ending March 31, 2026, and for the fiscal years ending March 31, 2028, 2029 and 2030, respectively. As of June 30, 2025, the Company did not have any other ongoing material contractual obligations for which cash flows were fixed and determinable. In the normal course of business, the Company enters into agreements with CROs for clinical trials and with vendors for nonclinical studies, manufacturing and other services and products for operating purposes, which agreements are generally cancellable by the Company at any time, subject to payment of remaining obligations under binding purchase orders and, in certain cases, nominal early-termination fees. These commitments are not deemed significant. There are certain contracts wherein the Company has a minimum purchase commitment, however, most of it is due and payable within one year. Contingencies The extent of the impact of geopolitical tensions, changes in inflation and interest rates, changes in international trade policies and tariffs and any resulting economic slowdown or recession on the Company’s future operational and financial performance will depend on certain developments, including the potential impact on the Company’s clinical trial plans and timelines, such as the enrollment, activation of additional clinical trial sites, and the results of the Company’s clinical trials, all of which are uncertain and cannot be predicted. At this point, the extent to which these events may impact the Company’s future financial condition or results of operations is uncertain.
