| Cell experiment [1]: | |
|
Cell lines |
MCF7-R1 cells |
|
Preparation Method |
100,000 MCF7-R1 cells were seeded into each well of a 12-well culture plate, allowed to adhere overnight, and treated with 10 nM Monomethyl Auristatin E (MMAE) or conjugates in the presence of 10 U/mL heparin for 72 h. Then the cells were harvested with a TrypLE Express solution, stained by Annexin V-FITC and propidium iodide, and analyzed by flow cytometry using a NovoCyte 2060R flow cytometer. |
|
Reaction Conditions |
10 nM; for 72 h |
|
Applications |
After 72 h of treatment of MCF7-R1 cells with 10 nM conjugates, the cells were mainly in the early stage of apoptosis. |
| Animal experiment [2]: | |
|
Animal models |
Mice |
|
Preparation Method |
The breast tumor models were prepared via subcutaneous injection of 1 × 106 4T1 cells. When the tumor volumes were approximately 100 mm3, mice were divided into three groups: (i) saline; (ii) Monomethyl Auristatin E (MMAE) (0.2 mg/kg); and (iii) FRRG-MMAE nanoparticles (equivalent dose of 0.2 mg/kg based on MMAE contents). The mice were treated once every three days, and tumor volumes were calculated as the smallest diameter 2 × largest diameter × 0.53. The mice with a tumor volume of 2000 mm3 or larger were counted as dead. The toxicity study of FRRG-MMAE nanoparticles was assessed via histology. |
|
Dosage form |
0.2 mg/kg |
|
Applications |
The results demonstrated that free MMAE-treated mice showed rapid tumor growth compared to FRRG-MMAE-treated mice during monitoring for 15 days.Finally, mice treated with free MMAE showed significant body weight loss owing to the severe toxicity; eventually, all the mice were dead within five days of treatment.These results show the significantly reduced MMAE-related toxicity in the FRRG-MMAE nanoparticle group. |

cAC10-vcMMAE, an anti-CD30-monomethyl auristatin E conjugate with potent and selective antitumor activity
Blood2003 Aug 15;102(4):1458-65.PMID: 12714494DOI: 10.1182/blood-2003-01-0039
The chimeric monoclonal antibody cAC10, directed against CD30, induces growth arrest of CD30+ cell lines in vitro and has pronounced antitumor activity in severe combined immunodeficiency (SCID) mouse xenograft models of Hodgkin disease. We have significantly enhanced these activities by conjugating to cAC10 the cytotoxic agent monomethyl auristatin E (MMAE) to create the antibody-drug conjugate cAC10-vcMMAE. MMAE, a derivative of the cytotoxic tubulin modifier auristatin E, was covalently coupled to cAC10 through a valine-citrulline peptide linker. The drug was stably attached to the antibody, showing only a 2% release of MMAE following 10-day incubation in human plasma, but it was readily cleaved by lysosomal proteases after receptor-mediated internalization. Release of MMAE into the cytosol induced G2/M-phase growth arrest and cell death through the induction of apoptosis. In vitro, cAC10-vcMMAE was highly potent and selective against CD30+ tumor lines (IC50 less than 10 ng/mL) but was more than 300-fold less active on antigen-negative cells. In SCID mouse xenograft models of anaplastic large cell lymphoma or Hodgkin disease, cAC10-vcMMAE was efficacious at doses as low as 1 mg/kg. Mice treated at 30 mg/kg cAC10-vcMMAE showed no signs of toxicity. These data indicate that cAC10-vcMMAE may be a highly effective and selective therapy for the treatment of CD30+ neoplasias.
Microtubule and tubulin binding and regulation of microtubule dynamics by the antibody drug conjugate (ADC) payload, monomethyl auristatin E (MMAE): Mechanistic insights into MMAE ADC peripheral neuropathy
Toxicol Appl Pharmacol2021 Jun 15;421:115534.PMID: 33852878DOI: 10.1016/j.taap.2021.115534
Monomethyl auristatin E (MMAE) is a potent anti-cancer microtubule-targeting agent (MTA) used as a payload in three approved MMAE-containing antibody drug conjugates (ADCs) and multiple ADCs in clinical development to treat different types of cancers. Unfortunately, MMAE-ADCs can induce peripheral neuropathy, a frequent adverse event leading to treatment dose reduction or discontinuation and subsequent clinical termination of many MMAE-ADCs. MMAE-ADC-induced peripheral neuropathy is attributed to non-specific uptake of the ADC in peripheral nerves and release of MMAE, disrupting microtubules (MTs) and causing neurodegeneration. However, molecular mechanisms underlying MMAE and MMAE-ADC effects on MTs remain unclear. Here, we characterized MMAE-tubulin/MT interactions in reconstituted in vitro soluble tubulin or MT systems and evaluated MMAE and vcMMAE-ADCs in cultured human MCF7 cells. MMAE bound to soluble tubulin heterodimers with a maximum stoichiometry of ~1:1, bound abundantly along the length of pre-assembled MTs and with high affinity at MT ends, introduced structural defects, suppressed MT dynamics, and reduced the kinetics and extent of MT assembly while promoting tubulin ring formation. In cells, MMAE and MMAE-ADC (via nonspecific uptake) suppressed proliferation, mitosis and MT dynamics, and disrupted the MT network. Comparing MMAE action to other MTAs supports the hypothesis that peripheral neuropathy severity is determined by the precise mechanism(s) of each individual drug-MT interaction (location of binding, affinity, effects on morphology and dynamics). This work demonstrates that MMAE binds extensively to tubulin and MTs and causes severe MT dysregulation, providing convincing evidence that MMAE-mediated inhibition of MT-dependent axonal transport leads to severe peripheral neuropathy.
Monomethyl Auristatin E Grafted-Liposomes to Target Prostate Tumor Cell Lines
Int J Mol Sci2021 Apr 15;22(8):4103.PMID: 33921088DOI: 10.3390/ijms22084103
Novel nanomedicines have been engineered to deliver molecules with therapeutic potentials, overcoming drawbacks such as poor solubility, toxicity or short half-life. Lipid-based carriers such as liposomes represent one of the most advanced classes of drug delivery systems. A Monomethyl Auristatin E (MMAE) warhead was grafted on a lipid derivative and integrated in fusogenic liposomes, following the model of antibody drug conjugates. By modulating the liposome composition, we designed a set of particles characterized by different membrane fluidities as a key parameter to obtain selective uptake from fibroblast or prostate tumor cells. Only the fluid liposomes made of palmitoyl-oleoyl-phosphatidylcholine and dioleoyl-phosphatidylethanolamine, integrating the MMAE-lipid derivative, showed an effect on prostate tumor PC-3 and LNCaP cell viability. On the other hand, they exhibited negligible effects on the fibroblast NIH-3T3 cells, which only interacted with rigid liposomes. Therefore, fluid liposomes grafted with MMAE represent an interesting example of drug carriers, as they can be easily engineered to promote liposome fusion with the target membrane and ensure drug selectivity.
Disitamab Vedotin: First Approval
Drugs2021 Nov;81(16):1929-1935.PMID: 34661865DOI: 10.1007/s40265-021-01614-x
Disitamab vedotin (Aidixi?) is an antibody-drug conjugate comprising a monoclonal antibody against human epidermal growth factor receptor 2 (HER2) conjugated via a cleavable linker to the cytotoxic agent monomethyl auristatin E. Disitamab vedotin is being developed by RemeGen for the treatment of solid tumours, including gastric cancer; Seagen has the right to develop disitamab vedotin globally outside of RemeGen's territory. In June 2021, disitamab vedotin received its first Biologics License Application (BLA) approval in China for the treatment of patients with HER2-overexpressing (defined as IHC2+ or 3+) locally advanced or metastatic gastric cancer (including gastroesophageal junction adenocarcinoma) who have received at least two systemic chemotherapy regimens. Disitamab vedotin as monotherapy or combination therapy is also in clinical development for the treatment of other solid tumours globally, including urothelial cancer in China and the USA, and biliary tract cancer, non-small cell lung cancer and HER2-positive and HER2-low expressing breast cancer in China. This article summarizes the milestones in the development of disitamab vedotin leading to this first approval for locally advanced or metastatic gastric cancer.
