Toviblideg
Based on 1 Customer Validation
Toviblideg (BMS-986458) is a highly selective, orally active cereblon-based BCL6 PROTAC degrader and antitumor agent. Toviblideg selectively degrades BCL6 by binding cereblon to the BTB domain of BCL6, thereby regulating the cell cycle, antiproliferative and interferon signaling pathways, and upregulating the expression and distribution of CD20. Toviblideg modulates the phenotype of follicular helper T cells and reduces circulating tumor DNA levels. The combination of Toviblideg with CD20xCD3 bispecific antibody also enhances the efficiency of T cell tumor infiltration and expansion. Toviblideg induces regression of BCL6-positive tumors and prolongs survival, and it is suitable for research related to B-cell non-Hodgkin lymphoma, diffuse large B-cell lymphoma, follicular lymphoma, and relapsed/refractory lymphoma.

Toviblideg (BMS-986458) (5 mg/kg; p.o.; BID) monotherapy induces tumor volume reduction and modest CD3+ cell infiltration at the tumor edge, and its combination with Glofitamab demonstrates synergistic antitumor efficacy with enhanced CD3+ cell tumor infiltration in a humanized DLBCL mouse model[3].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:hCRBN NSG mouse Diffuse large B-cell lymphoma (DLBCL) model[3]
-
Dosage:5 mg/kg; with Glofitamab (1 μg/mouse IV QW)
-
Administration:p.o.; BID
-
Result:Induced 59% tumor volume reduction compared to vehicle; showed modest increase in CD3⁺ cells predominantly at the tumor’s edge following 2 weeks of treatment; when combined with glofitamab, achieved 97% tumor volume reduction, 6/8 tumor-free mice, and significant increase in CD3⁺ cell tumor infiltration compared to other groups.

Solvent & Solubility
DMSO : 100 mg/mL (159.21 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (3.98 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.

The co-solvents required include: DMSO, . All of co-solvents are available by MedChemExpress (MCE). , Tween 80. All of co-solvents are available by MedChemExpress (MCE).
Working solution concentration: 0.22 mg/mL
Method for preparing stock solution: mg drug dissolved in μL DMSO. Stock solution concentration: mg/mL.
1. Take μL DMSO stock solution;
2. Add μL .
