Akari Therapeutics Releases CEO Corner Reflecting on Evolving ADC Landscape and Akari’s Differentiated PH1 Payload Platform Following ASCO 2026

On June 4, 2026 Akari Therapeutics, Plc (Nasdaq: AKTX), an oncology biotechnology company developing antibody drug conjugates (ADCs) with novel RNA splicing modulator payloads, reported a new CEO Corner segment featuring President and Chief Executive Officer Abizer Gaslightwala discussing key themes emerging from the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and Akari’s positioning within the evolving ADC landscape.

In the segment, Mr. Gaslightwala reflects on the accelerating pace of innovation across oncology and the growing industry focus on difficult-to-treat, genetically defined cancers, particularly KRAS-driven tumors such as pancreatic, lung and colon cancers where significant unmet need remains today.

Mr. Gaslightwala also discusses the continued momentum surrounding ADC development and what he believes represents the industry’s transition toward "ADC 2.0," driven by increasing demand for differentiated payload technologies capable of overcoming limitations associated with existing Top1 and MMAE payload classes.

The discussion highlights emerging clinical data presented at ASCO (Free ASCO Whitepaper) suggesting limited efficacy when patients receive sequential ADC therapies utilizing the same payload class following relapse, reinforcing the growing need for novel payload approaches across the ADC landscape.

As part of the CEO Corner, Mr. Gaslightwala discusses Akari’s proprietary PH1 spliceosome-modulating payload platform and why the Company believes its differentiated mechanism may potentially help address resistance challenges observed with current ADC approaches while expanding therapeutic applicability across multiple difficult-to-treat solid tumors.

The segment also highlights Akari’s first accepted ASCO (Free ASCO Whitepaper) abstract featuring preclinical data demonstrating combination synergy between the PH1 ADC payload and a KRAS inhibitor in KRAS-mutated pancreatic cancer models, further supporting the potential applicability of Akari’s novel payload platform within the rapidly evolving KRAS therapy landscape.

In addition, Mr. Gaslightwala outlined several anticipated milestones investors should monitor throughout the remainder of 2026, including continued advancement of Akari’s PH1 spliceosome-modulating payload platform and the Company’s planned initiation of its Phase 1 first-in-human clinical trial for its lead development candidate AKTX-101which is expected by mid-2027.

Abeona Therapeutics Inc. participated in a Pre-IND meeting with the US FDA

On June 3, 2026, Abeona Therapeutics Inc. (the "Company") reported to have participated in a pre-Investigational New Drug application ("Pre-IND") meeting with the U.S. Food and Drug Administration ("FDA") regarding ABO-701, a recently licensed radically novel engineered T-cell therapy, targeting Prostate-Specific Membrane Antigen to treat prostate cancer. While official minutes of the meeting have not yet been received, we believe the meeting was constructive and continues to target submission of an IND application for ABO-701 in 2027, consistent with our previously stated timeline.

We can provide no assurance that the FDA will not require additional studies, data, or information before accepting an IND submission for ABO-701, or that any IND submission, if submitted, will be accepted by the FDA or result in authorization to commence clinical trials. Our development plans remain subject to ongoing evaluation and may be revised based on, among other things, feedback received from the FDA, results of preclinical studies, manufacturing considerations, and other factors.

SOTIO Receives U.S. FDA Orphan Drug Designation for SOT106, a Potential Best-in-Class ADC for Sarcoma

On June 3, 2026 SOTIO Biotech, a clinical-stage biopharmaceutical company owned by PPF Group, reported that the U.S. Food and Drug Administration (FDA) has granted Orphan Drug Designation (ODD) to SOT106 for the treatment of osteosarcoma, reinforcing its potential as a targeted therapy for this high unmet need population.

SOT106 is a next-generation antibody-drug conjugate (ADC) targeting leucine-rich repeat-containing 15 (LRRC15), a clinically validated target broadly expressed across sarcoma subtypes and in tumor associated stroma. The program is designed to deliver an early and actionable clinical signal, with expansion potential across multiple solid tumors. Preclinical data demonstrate strong anti-tumor activity in both soft tissue and osteosarcoma models and favorable tolerability supporting a high therapeutic index. SOTIO expects to initiate a first-in-human clinical trial of SOT106 in the second half of 2026.

"Orphan Drug Designation for SOT106 underscores both the urgent need for new treatment options in osteosarcoma and the strength of our ADC platform," said Radek Spisek, M.D., Ph.D., chief executive officer of SOTIO. "Osteosarcoma is a devastating disease that has seen little therapeutic innovation over the past four decades. Treatment continues to rely on intensive chemotherapy regimens associated with significant toxicities and limited long-term benefit. We are encouraged by this recognition from the FDA and look forward to advancing SOT106 into the clinic later this year."

Sarcomas are a diverse group of cancers arising in bones and soft tissues and comprising more than 70 distinct subtypes. Their rarity and biological heterogeneity have made therapeutic innovation challenging, including the development of targeted approaches such as ADCs. Patients today are primarily treated with a combination of surgery, radiation and/or chemotherapy, yet outcomes remain poor for patients with aggressive, recurrent or metastatic disease. This need is especially clear in osteosarcoma, the most common bone cancer in children and adolescents, where a significant number of patients require amputation of the affected limb.

ODD provides several incentives to support the development of therapies for rare diseases and areas of high unmet need, including the potential for seven years of market exclusivity upon approval, waivers of certain regulatory fees, and enhanced interaction with and guidance from the U.S. FDA throughout the development process.

Perspective Therapeutics Expands Therapeutic Focus Areas; First Patient Dosed with [212Pb]VMT-α-NET in the Meningioma Cohort of a Phase 1/2a Study

On June 3, 2026 Perspective Therapeutics, Inc. ("Perspective," the "Company," "we," "us," and "our") (NYSE AMERICAN: CATX), a radiopharmaceutical development company pioneering advanced treatments for cancers throughout the body, reported that the first meningioma patient was dosed with [212Pb]VMT-α-NET in the Company’s ongoing Phase 1/2a study.

The new cohort is intended to evaluate the safety, dosimetry, and preliminary anti-tumor activity of lead-based alpha-particle therapy with [212Pb]VMT-α-NET for meningioma (LEMONαDE). The initiation of the meningioma cohort reflects The Company’s broader strategy to evaluate [212Pb]VMT-α-NET across somatostatin receptor subtype 2 (SSTR2)-expressing tumor types beyond neuroendocrine tumors (NETs).

Meningiomas are the most common primary brain tumors in adults, accounting for ~40% of all central nervous system tumors diagnosed annually in the United States1. Approximately 20% of all diagnosed meningioma cases are grades 2 and 3 by World Health Organization (WHO) 2021 grading,2 while approximately 30% of patients with diagnosed grade 1 disease either have inoperable disease or experience recurrence of their disease.3 Although surgery and radiation remain standard treatments, patients with recurrent, progressive, or unresectable disease often face limited therapeutic options and poor long-term outcomes.2 Meningiomas consistently express SSTR24, making them an attractive target for targeted radiopharmaceutical therapy.

About [212Pb]VMT-α-NET
Perspective designed [212Pb]VMT-α-NET to target and deliver 212Pb to tumor sites expressing SSTR2. The Company is conducting a multi-center, open-label, dose-escalation, dose-expansion study (clinicaltrials.gov identifier NCT05636618) of [212Pb]VMT-α-NET in patients with unresectable or metastatic SSTR2-positive tumors who have not received prior radiopharmaceutical therapies (RPT).

Interim analysis with a data cut-off date of April 17, 2026 was recently reported at the 2026 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in May 2026, including efficacy data on half of the patients in Cohort 2 and both patients in Cohort 1. Initial efficacy data for the remaining patients in Cohort 2 and eight patients in Cohort 3 are pending, and submissions for presentations at additional medical conferences during 2026 are planned.
