Three posters featuring updated ivonescimab data will be displayed on Friday, March 27 from 1:00 to 2:00 pm Central European Time. Data for HARMONi was generated and analyzed by Summit and for HARMONi-2 by our collaboration and licensing partner, Akeso. The first poster, "Intracranial Efficacy of Ivonescimab Plus Chemotherapy in Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor-Resistant, EGFR-Mutated Non-Small Cell Lung Cancer in the HARMONi Study" includes outcome data from patients with and without asymptomatic brain metastases at baseline enrolled in HARMONi. These patients received either ivonescimab delivered in combination with chemotherapy, or chemotherapy alone in this global Phase III trial for patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who were previously treated with an EGFR TKI. Ivonescimab plus chemotherapy demonstrated an improvement in intracranial progression free survival in patients with baseline brain metastases of 10.1 months compared to 6.5 months for chemotherapy. In patients who did not have baseline CNS metastases, the addition of ivonescimab also showed an improvement in intracranial PFS over control arm with 15.7 months compared to 11.6 months. No new safety signals were identified across baseline brain metastasis subgroups. The second poster, "Health-Related Quality of Life in Patients Previously Treated with an EGFR-TKI from HARMONi: A Phase 3 Trial of Ivonescimab vs Placebo Plus Chemotherapy" includes data from patients enrolled in HARMONi. These patients received either ivonescimab delivered in combination with chemotherapy, or chemotherapy alone in this global Phase III trial for patients with EGFR-mutated, locally advanced or metastatic non-squamous NSCLC who were previously treated with an EGFR TKI. The third poster, "Health-Related Quality of Life with Ivonescimab Versus Pembrolizumab for PD-L1 Positive, NSCLC: a Randomised, Double-Blind, Phase 3 Study in China" includes data from patients enrolled in HARMONi-2 or AK112-303. These patients received either ivonescimab delivered as monotherapy, or pembrolizumab delivered as monotherapy in this Phase III study conducted exclusively in China for patients with locally advanced or metastatic NSCLC whose tumors have positive PD-L1 expression with all data collected and analyzed by Akeso.Hear more from InvestingChannel by signing up for.About "Biotech Alert"The Fly will report on a selection of biotech stocks seeing a surge in interest from retail and financial professional investors, based on data from InvestingChannel.This Fly exclusive recap reveals the biotech stocks that are seeing a spike in searches among the 20-plus million retail and financial professional investors through InvestingChannel's online financial news media ecosystem.This increased attention from the investors may be in response to, or advance of, outsized moves for stocks in the biotech sector, which tend to be volatile and prone to sharp swings in share price around binary events such as clinical study results and FDA approvals.

- Trial Launch: Radiopharm Theranostics announced that the first patient has been dosed in the Phase 1 clinical trial of RAD 402, which aims to evaluate safety and preliminary efficacy for prostate cancer, marking a significant advancement in the company's innovative oncology treatments.
- Targeting Mechanism Innovation: RAD 402 is a monoclonal antibody targeting KLK3, radiolabelled with Terbium 161, with preclinical data showing strong tumor targeting in mouse xenografts while exhibiting minimal bone marrow uptake and expected hepatic clearance, indicating its potential for clinical application.
- Dose Escalation Design: The Phase 1 trial employs a dose escalation design to determine the Maximum Tolerated Dose (MTD) and recommended Phase 2 Dose (RP2D), laying the groundwork for future clinical expansion and reflecting the company's commitment to this program and its patients.
- Partner Support: Radiopharm CEO Riccardo Canevari expressed gratitude to TerThera and Cyclotek for their support in supplying Tb161, radiolabelling, and distributing RAD 402, highlighting the importance of collaboration in advancing innovative therapeutic solutions.

- Mechanism of Action: 177Lu-BetaBart is a monoclonal antibody targeting B7-H3, which has shown potential for tumor shrinkage and prolonged survival in preclinical studies, particularly demonstrating good targeting in various tumor types including prostate, pancreatic, and breast cancers.
- Trial Scale: The clinical trial aims to enroll 61 eligible participants across multiple cancer types, including castrate-resistant prostate cancer and small cell lung cancer, with the goal of assessing the safety and pharmacokinetics of 177Lu-BetaBart.
- Strategic Implications: This study not only showcases Radiopharm's innovative capabilities in the development of radiopharmaceuticals but also positions the company for a significant competitive advantage in the highly competitive oncology market, potentially driving future commercial growth.

- Clinical Trial Results: In the Phase 2b trial of RAD 101 for patients with brain metastases, 92% of evaluable participants met the primary endpoint of MRI concordance, and if confirmed, this will trigger preparations for a multi-center Phase 3 registrational trial.
- Strong Financial Position: As of December 31, 2025, Radiopharm reported cash and cash equivalents of approximately $34.52 million, up from $29.12 million at year-end, providing a runway into 2027 to advance high-value radiotherapeutic programs.
