Summary · why it matters

Asahi Kasei Therapeutics, the global specialty pharmaceutical business of Tokyo-based Asahi Kasei, announced that the first patient has been dosed in a randomized Phase 2a clinical trial evaluating AIC468, a novel antiviral antisense oligonucleotide, in adult kidney transplant recipients with BK virus infection. The trial, registered as NCT07503561, is a randomized, double-blind, placebo-controlled study and forms part of a larger Phase 2/3 program designed to assess safety, tolerability, and pharmacokinetic profile across multiple dose levels, measured by the frequency and severity of treatment-emergent adverse events. Progression into Phase 2a was supported by favorable Phase 1 safety, tolerability, and pharmacokinetic data, and the investigational program was developed by Aicuris Anti-infective Cures AG, which is now part of Asahi Kasei Therapeutics. Carl Kraus, Chief Medical Officer of Asahi Kasei Therapeutics, said BK virus reactivation remains a major complication for kidney transplant recipients that can lead to graft dysfunction and BK nephropathy, and that dosing the first patient represents an important step toward a targeted antiviral therapy for a community with no approved treatment options. BK virus-associated nephropathy affects up to 10% of kidney transplant recipients and can result in graft loss, while current management relies on reducing immunosuppressive therapy, which increases the risk of graft rejection.

MicuRx Pharmaceuticals Signs Exclusive License Agreement for MRX-23 with Milestone Payments Capped at 750 Million US Dollars

MicuRx Pharmaceuticals has signed an exclusive license agreement and a platform technology collaboration agreement with Switzerland's ClearideBio for the MRX-23 project. The nominal cap on milestone payments for the development, registration, and sales of MRX-23 totals 223 million US dollars, while the cap for all platform collaboration projects, if all options are exercised and all milestones are achieved, totals 750 million US dollars. Under the agreement, an upfront payment of 1 million US dollars is payable as agreed after the agreement takes effect and is non-refundable, and near-term development milestone payments are triggered by the first approval of a clinical trial application for the licensed product. Biwin Storage Technology announced that as of September 30, 2026, it had cumulatively repurchased 1,044,700 shares, accounting for 0.22 percent of total share capital, with a total payment of 222 million yuan. The repurchase plan is expected to involve a total amount of 200 million to 250 million yuan. Sino Medical Sciences Technology's coronary balloon dilatation catheter has received approval from Colombia's INVIMA and obtained a medical device registration certificate. Jiangsu Jindike Biotechnology's trivalent influenza vaccine has obtained a drug registration certificate, but the company expects full-year revenue may fall below 100 million yuan and it will not be able to turn a profit. If it triggers the financial delisting risk warning conditions, the Shanghai Stock Exchange will impose a delisting risk warning on the company's shares.

SymBio Pharmaceuticals begins talks with MHRA toward conditional early approval of brincidofovir in the UK

SymBio Pharmaceuticals announced that it has begun consultations with the UK Medicines and Healthcare products Regulatory Agency toward obtaining conditional early marketing authorization in the UK for brincidofovir, which targets adenovirus infection following hematopoietic stem cell transplantation. The UK's conditional early marketing authorization scheme is a framework that grants early market access for medicines addressing unmet medical needs such as life-threatening diseases, even before comprehensive clinical data are available, when the confirmed benefits are judged to outweigh the risks; after approval, continued data collection and monitoring of safety and efficacy are mandatory. While advancing the process toward obtaining this approval, the company will also complete its global Phase III clinical trial, currently underway in the United States and Europe, as quickly as possible and focus on establishing evidence of high medical validity. As of September 17, 2026, the trial had enrolled 30 patients, with targets of 69 patients by the end of 2026 and 180 patients by the end of 2027. Brincidofovir is a compound for which the company acquired global rights in September 2019, and it is advancing development centered on three therapeutic areas: post-transplant viral infections, cancer, and neurodegenerative diseases. This matter will have no impact on the company's consolidated earnings forecast for the fiscal year ending December 2026.

Moberg Pharma Publishes New Analyses on Terbinafine Susceptibility and MOB-015 in Journal of Fungi

Moberg Pharma AB announced the publication of new analyses demonstrating potent antifungal activity of terbinafine against dermatophytes causing onychomycosis, with mycological cure achieved with MOB-015 across the full range of baseline terbinafine susceptibility, including in patients with reduced in vitro susceptibility. The analyses are based on data from the previously completed North American Phase 3 study evaluating daily treatment with MOB-015 for 48 weeks, and included 506 dermatophyte isolates from onychomycosis patients. Only 3.2% of baseline isolates showed elevated MIC values of at least 0.5 micrograms per milliliter, and among MOB-015-treated patients with evaluable end-of-study results, 74.3% achieved mycological cure, including two of three patients with elevated baseline MIC values. The work was conducted in collaboration with Professor Mahmoud Ghannoum at Case Western Reserve University in Cleveland, Ohio, and the article, titled In Vitro Terbinafine Susceptibility of Dermatophytes and Mycological Cure Outcomes from a Multicenter Phase III Onychomycosis Trial, is published in Journal of Fungi, 2026, 12(10), 739. Amir Tavakkol, CSO of Moberg Pharma, said the results are encouraging, particularly given the increasing attention to antifungal resistance, and that the findings further strengthen the scientific foundation for MOB-015.
