SPRING BRANCH, Texas, March 11, 2026 (GLOBE NEWSWIRE) -- Callan JMB Inc. (NASDAQ:CJMB), ("Callan JMB" or the "Company"), an integrative logistics company empowering the healthcare industry and emergency management agencies through fulfillment, storage, monitoring, and cold chain logistics services, today announced that it has agreed with Biostax Corp d/b/a Attune Biotech Inc. ("Attune"), a clinical-stage biopharmaceutical company with a diversified therapeutic pipeline, to support its investigational new drug clinical trials for the treatment of Post-Acute Sequelae of SARS-CoV-2 infection ("PASC"), commonly known as Long COVID.

The Company previously announced in January 2026, that it had signed a strategic teaming agreement with Attune, whereby Callan JMB serves as independent third-party overseer of Attune's manufacturing, quality assurance and control, and deployment operations. Under this agreement, Callan JMB will provide the following services and oversight for IND 181314 for JKB-122 (lodonal™), including Contract Manufacturing Organization (CMO) qualification and validation, comprehensive batch record review, supply chain verification and integrity confirmation, surge manufacturing capacity assessment, and distribution pathway validation.

Attune has received notification that the U.S. Food and Drug Administration (FDA) has received and assigned Investigational New Drug (IND) application number 181314 for JKB-122 (lodonal™) for treatment of Long COVID, which remains a condition for which no FDA-approved therapies are currently indicated. Patients of Long COVID are currently underserved, with approximately 20 million Americans estimated to be living with Long COVID or persistent post-COVID symptoms1. In addition, the U.S. Department of Health and Human Services (HHS) has issued formal guidance titled "Long COVID as a Disability Under the ADA, Section 504, and Section 1557" (last reviewed July 2025), confirming that Long COVID may qualify as a disability under federal civil rights statutes where symptoms substantially limit major life activities.

lodonal™ (JKB-122) is a first-in-class TLR4 antagonist for immune restoration, currently in development across five parallel clinical programs including Long COVID, HIV immune non-responders, autoimmune hepatitis, metabolic liver diseases (MASLD/MASH), and chronic immune pain. Under IND 181314, Attune intends to initiate a randomized, double-blind, placebo-controlled, multi-center Phase 2b/3 clinical trial evaluating the safety, tolerability, and efficacy of JKB-122 (lodonal™) in adults diagnosed with PASC or Long COVID. The product remains investigational and has not been approved by the U.S. Food and Drug Administration. JKB-122 is protected by issued intellectual property extending through 2041.
