(Nasdaq: NXTC), a clinical-stage biopharmaceutical company committed to discovering and developing novel therapies to treat cancer, today provided a business update and reported second quarter 2026 financial results. "Following quarter end, we announced our proposed merger with Avere Therapeutics, together with Avere’s concurrent private financing expected to generate approximately $320 million in gross proceeds, and we are working toward a closing in the second half of 2026. In parallel, we are preserving capital in support of that closing. Our team continues to support the ongoing clinical programs and obligations to our partners, and opportunities to preserve value for our shareholders,” said Michael Richman, President and CEO of NextCure. Recent Business Highlights Announced a definitive merger agreement with Avere Therapeutics in an all-stock transaction. Upon closing, the combined company is expected to operate as Avere Therapeutics and trade on Nasdaq under the ticker symbol “AVRX”. Existing NextCure stockholders are expected to receive contingent value rights (“CVRs”) tied to certain legacy NextCure assets. Concurrently, Avere Therapeutics entered into a securities purchase agreement providing for a private financing expected to generate approximately $320 million in gross proceeds immediately prior to closing of the merger, subject to customary closing conditions. Entered into a Transition and Continuation Agreement with LigaChem Biosciences (“LigaChem”) under which LigaChem has elected to continue the development of LNCB74 as the “Sole Developing Party” pursuant to the terms under the parties’ November 2022 Research Collaboration and Co-Development Agreement.

Initiated efforts to preserve value of SIM0505 and our current clinical and pre-clinical assets for our shareholders. Financial Results for the Quarter Ended June 30, 2026 Cash, cash equivalents, and marketable securities as of June 30, 2026 were $20.1 million as compared to $41.8 million as of December 31, 2025. The decrease of $21.7 million was primarily due to cash used to fund operations of $23.1 million, partially offset by proceeds of $1.2 million from equity sales under our existing ATM program. In connection with the proposed merger with Avere Therapeutics and related restructuring activities, NextCure is focused on preserving capital, completing the proposed transaction and pursuing efforts to preserve value of our current clinical and pre-clinical assets. Research and development expenses were $7.4 million for the three months ended June 30, 2026, as compared to $24.1 million for the three months ended June 30, 2025. The decrease of $16.7 million was due to $17.0 million of license fees incurred in the prior year that did not occur in the current year. General and administrative expenses were $2.6 million for the three months ended June 30, 2026, as compared to $3.2 million for the three months ended June 30, 2025. The decrease of $0.6 million was primarily related to lower personnel related costs. Asset impairment costs associated with our recently announced restructuring initiatives to reduce our footprint and sell certain facility and laboratory assets totaled $5.1 million in the second quarter. Net loss was $14.9 million for the three months ended June 30, 2026, as compared to a net loss of $26.8 million for the three months ended June 30, 2025. The lower net loss for the three months ended June 30, 2026 as compared to the three months ended June 30, 2025 was driven by the lower research and development and general and administrative expenses mentioned above, partially offset by impairment costs of $5.1 million and lower other income, net, of $0.3 million.

SIM0505/CDH6 ADC dose optimization initiated in gynecologic cancers SIM0505 Phase 1 dose escalation study data to be presented at ASCO 2026 LNCB74 Phase 1 dose escalation trial update planned in second half of 2026 BELTSVILLE, Md., May 07, 2026 (GLOBE NEWSWIRE) -- NextCure, Inc. (Nasdaq: NXTC), a clinical-stage biopharmaceutical company committed to discovering and developing novel therapies to treat cancer, today provided a business update and reported first quarter 2026 financial results. "Our SIM0505 program reached critical milestones this quarter, headlined by the U.S. Food and Drug Administration (FDA) granting Fast Track designation for platinum-resistant ovarian cancer (PROC) and the upcoming presentation of initial Phase 1 data at the American Society for Clinical Oncology (ASCO 2026)," said Michael Richman, President and CEO of NextCure. "We believe Fast Track designation validates the potential of this CDH6 antibody drug conjugate (ADC) and the urgent need for new therapies. As we prepare to present our data at ASCO 2026, we are also focusing on accelerating development, with plans to increase our U.S. trial sites and expand our footprint into Canada and Europe. With the recent initiation of the dose optimization this month, we are fully committed to bringing this transformative treatment to patients." Business Highlights and Near-Term Milestones SIM0505 (CDH6 ADC): Phase 1 dose escalation data expected in Q2 2026 SIM0505 is a novel ADC directed to cadherin-6 (CDH6 ADC), overexpressed in several cancers including ovarian cancer, with limited expression in healthy tissues. SIM0505 features a proprietary topoisomerase 1 inhibitor (TOPOi) payload, designed for broad anti-tumor activity, fast systemic clearance and an improved potential therapeutic window. Received Fast Track designation for the treatment of women with PROC from the FDA. Data from the Phase 1 open-label dose escalation study in patients with advanced solid tumors with a focus on gynecological cancers and an emphasis on PROC (NCT06792552) are expected to be presented at ASCO 2026 on June 1, 2026, including results from patients in the U.S. and China. Announced in May 2026 the initiation of the Phase 1 dose optimization study in gynecologic cancers by dosing patients with PROC. NextCure anticipates increasing the number of trial sites in the second half of 2026, including the activation of sites in Canada and Europe, with continued study site additions in 2027. LNCB74 (B7-H4 ADC): Ongoing enrollment in Phase 1 dose escalation LNCB74 is a novel ADC directed to B7-H4, overexpressed in several cancers, with limited expression in healthy tissues. LNCB74 features a proprietary tumor-selective cleavable linker and a tubulin inhibitor monomethyl auristatin E (MMAE) payload. Ongoing open-label Phase 1 dose escalation study (NCT06774963) continues to prioritize patients with high B7-H4 expression in breast and gynecological cancers, as well as the inclusion of patients with adenoid cystic carcinoma type 1. NextCure intends to backfill patients to investigate particular dose levels and schedules in the expected therapeutic window. Trial progress update planned in the second half of 2026. Financial Results for the Quarter Ended March 31, 2026 Cash, cash equivalents, and marketable securities as of March 31, 2026 were $29.7 million as compared to $41.8 million as of December 31, 2025. The decrease of $12.1 million was primarily due to cash used to fund operations of $13.4 million, partially offset by proceeds of $1.2 million from equity sales under our existing ATM program. NextCure expects current financial resources to be sufficient to fund operating expenses and capital expenditures into the first half of 2027 through proof-of-concept for SIM0505. Research and development expenses were $6.8 million for the three months ended March 31, 2026, as compared to $7.9 million for the three months ended March 31, 2025. The decrease of $1.1 million was due to lower costs related to deprioritized programs which were largely offset by costs for the SIM0505 program, and lower personnel costs, primarily non-cash stock compensation costs and lower depreciation. General and administrative expenses were $3.3 million for the three months ended March 31, 2026, as compared to $3.7 million for the three months ended March, 2025. The decrease of $0.4 million was primarily related to lower non-cash stock compensation costs. Net loss was $9.8 million for the three months ended March 31, 2026, as compared to a net loss of $11.0 million for the three months ended March 31, 2025. The lower net loss for the three months ended March 31, 2026 as compared to the three months ended March 31, 2025 was driven by the lower research and development and general and administrative expenses mentioned above, partially offset by lower other income of $0.3 million.

We believe the ability to dose at levels that match or exceed competitor CDH6-targeting ADCs should demonstrate the promise of this program. We also received FDA clearance for our LNCB74 protocol amendment, giving us the ability to add higher dose escalation cohorts. We plan to provide proof of concept data readouts on SIM0505 and LNCB74 in the first half of 2026.” Business Highlights and Near-Term Milestones SIM0505 (CDH6 ADC) A novel antibody drug conjugate (ADC) directed to cadherin-6 (CDH6 ADC), featuring a proprietary topoisomerase 1 inhibitor (TOPOi) payload, designed for broad anti-tumor activity, fast systemic clearance and an improved potential therapeutic window. Acquired global rights in June 2025, excluding greater China where Simcere Zaiming retained rights. First U.S. patient dosed in October 2025 at a mid-tier dose level where multiple responses have been observed along with good tolerability in the ongoing Chinese trial. Proof of concept data readout, including data from Simcere Zaiming’s ongoing Phase 1 trial, in the first half of 2026. LNCB74 (B7-H4 ADC) A novel ADC directed to B7-H4, featuring a proprietary tumor-selective cleavable linker and a tubulin inhibitor monomethyl auristatin E (MMAE) payload. Co-developed with LigaChem Biosciences Inc. in a 50-50 cost share arrangement. Received Food and Drug Administration (FDA) acceptance of a protocol amendment giving us the ability to add higher dose escalation cohorts. Proof of concept data readout in the first half of 2026. Financial Results for Quarter Ended September 30, 2025 Cash, cash equivalents, and marketable securities as of September 30, 2025 were $29.1 million as compared to $68.6 million as of December 31, 2024. The decrease of $39.5 million was primarily due to cash used to fund operations, including the $12.0 million upfront license fee to Simcere Zaiming. We expect current financial resources to be sufficient to fund operating expenses and capital expenditures into mid-2026. Research and development expenses were $6.1 million for the three months ended September 30, 2025, as compared to $8.8 million for the three months ended September 30, 2024. The decrease of $2.6 million was due to lower costs related to deprioritized programs, lower preclinical development costs and lower personnel-related costs. General and administrative expenses were $2.8 million for the three months ended September 30, 2025, as compared to $3.7 million for the three months ended September 30, 2024. The decrease of $0.9 million was primarily related to lower personnel costs. Net loss was $8.6 million for the three months ended September 30, 2025, as compared to a net loss of $11.5 million for the three months ended September 30, 2024 due to the lower research and development costs and lower general and administrative costs as described above, partially offset by lower other income.
