Methods: Our submission showcases UB4A and CP15, novel cyclic peptides for treating multiple myeloma. They target key pathways, combat drug resistance, and offer promising preclinical efficacy. Sharing at IMS advances oncology, benefiting patients worldwide. Keywords: Multiple Myeloma, Cyclic Peptides, UB4A, CP15, Therapeutics, Drug Resistance, Preclinical Studies.
Results: In vitro studies evaluating the efficacy of UB4A and CP15 on multiple myeloma cell lines have demonstrated promising therapeutic potential. Treatment with both peptides exhibited notable efficacy, particularly in cell lines resistant to Bortezomib, a standard therapy for multiple myeloma. Furthermore, PK studies revealed favorable pharmacokinetic profiles for both peptides, with CP15 demonstrating no significant toxicity except at high doses, where a slight reduction in cell number was observed in normal cells. In vivo efficacy studies with UB4A revealed a significant attenuation in tumor growth, particularly in cell lines resistant to Bortezomib, with a remarkable 48% reduction in tumor size. Additionally, in vitro studies with CP15 exhibited even greater efficacy compared to UB4A, warranting further investigation through in vivo studies. These results underscore the promising therapeutic potential of UB4A and CP15 as novel treatments for multiple myeloma, with the potential to overcome resistance to existing therapies and improve patient outcomes.
Conclusions: In conclusion, the comprehensive characterization of UB4A and CP15 through a series of rigorous methodologies has provided valuable insights into their potential as promising therapeutic candidates for multiple myeloma. The successful synthesis and formulation of these cyclic peptides, coupled with their favorable pharmacokinetic profiles and demonstrated efficacy in preclinical models, underscore their promising therapeutic potential. These findings highlight the significance of UB4A and CP15 as innovative treatment modalities that hold promise for addressing the unmet medical needs of patients with multiple myeloma. Moving forward, further preclinical investigations and translational studies are warranted to validate and optimize these peptides for clinical development, ultimately advancing the landscape of multiple myeloma therapeutics and improving patient outcomes.
