Ixazomib citrate

Lund, June 9, 2025 – Active Biotech (NASDAQ Stockholm; ACTI) announced today that study results of its clinical drug candidate tasquinimod in heavily pretreated patients with relapsed refractory multiple myeloma (RRMM) are now available on Active Biotech’s website. The results were presented in a poster at the American Society of Clinical Oncology (ASCO) annual meeting May 30 – June 1, 2025. A total of 17 patients received tasquinimod in combination with ixazomib (proteasome inhibitor, PI), lenalidomide (Imid), and dexamethasone (IRd). Patients were heavily pretreated with a median of 7 prior lines of therapy (range 4-19) and all were triple-class refractory with 71% (12 patients) refractory to their most recent Imid/PI combination. In the total combination cohort, there was one partial response and 7 minimal responses which resulted in a 47% Clinical Benefit Rate (CBR). Among the 12 patients refractory to their latest Imid/PI combination there was one durable partial response (lasting 19.8 months) and three minimal responses (lasting 1.2, 1.5 and 6.7 months) resulting in a CBR of 33%. These patients were unlikely to respond to IRd alone and the result suggests synergistic efficacy of tasquinimod with the IRd combination. The results highlight the potential for targeting the tumor microenvironment with tasquinimod to augment the efficacy of other myeloma therapies. Tasquinimod was well tolerated in combination with IRd and the safety profile was in line with previous experience. The most common treatment emergent adverse events included fatigue, gastrointestinal events, pain and respiratory infections. Mostly of mild to moderate grade. The study (NCT04405167), was conducted at Abramson Cancer Center, Perelman School of Medicine, University of Pennsylvania, Philadelphia, PA with Dr. Dan Vogl as Principal Investigator. Full study results are being analyzed and will be published in a Scientific Journal. Information on the presentation: Abstract 7555, Clinical Activity of Novel Targeting of S100A9 with Tasquinimod for Relapsed and Refractory Multiple Myeloma (RRMM), Dan T. Vogl et al. was presented as a poster at the poster session Hematologic malignancies – Plasma cell dyscrasia on June 1, 2025. The poster is now available on Active Biotech’s website.

HEFEI, China I February 25, 2025 I Kangpu Biopharmaceuticals, Ltd. (“Kangpu”) today announced that the Company has received IND approval from the CDE (Center for Drug Evaluation) of China National Medical Products Administration (NMPA) for KPG-818 for the treatment of relapsed/refractory multiple myeloma (RRMM). KPG-818 is a novel oral molecular glue modulator of the E3 ubiquitin ligase complex CRL4-CRBN. It demonstrated high cereblon (CRBN) binding affinity and potent degradation of Aiolos (IKZF3) and Ikaros (IKZF1), two members of the Ikaros family of zinc-finger transcription factors associated with B-cell development. KPG-818 possesses immunomodulatory, anti-angiogenic, and anti-tumor effects. The Phase I clinical trial of KPG-818 in the United States for the treatment of various hematological tumors has been completed. Preliminary results indicate that in RRMM patients who have previously received two immunomodulatory drugs (lenalidomide and pomalidomide), at least one proteasome inhibitor (bortezomib, ixazomib, or carfilzomib), and a CD38 monoclonal antibody (daratumumab or isatuximab), KPG-818 demonstrated good safety, tolerability, pharmacokinetic characteristics, and encouraging therapeutic effects. About Kangpu Biopharmaceuticals Kangpu Biopharmaceuticals, Ltd. is a clinical-stage company focused on the discovery and development of innovative therapeutics for the treatment of solid tumors, hematologic malignancies, autoimmune diseases, and inflammatory disorders through novel solutions, including targeted protein degradation.
