Whether it's early-stage project evaluation and solution design, or later-stage process development and quality control, BOC Sciences offers full support to help clients succeed in the antibody-drug conjugate (ADC) field.
The conjugation ratio and stability of dual payload ADCs are key issues, particularly during drug preparation, where toxins may lose their potency due to uneven or unstable conjugation. BOC Sciences ensures that both toxins are stably and uniformly conjugated to the antibody by optimizing conjugation techniques and using efficient strategies.
Selecting two toxins with complementary mechanisms of action can enhance efficacy while reducing resistance and toxic side effects. BOC Sciences has an extensive toxin library and can design the optimal toxin combination tailored to specific therapeutic targets, maximizing their cytotoxic effects and minimizing toxicity to normal tissues.
Currently, dual payload ADC conjugation methods can be divided into single-point and dual-point conjugations, both of which directly affect the design and selection of the linker. BOC Sciences has deep technical expertise in linker design, offering custom linkers with specific release characteristics (e.g., enzyme-cleavable, reducible, acid-sensitive).
The preparation of dual payload ADCs involves more complex conjugation processes, requiring not only high conjugation efficiency but also ensuring that the toxins retain their activity throughout the conjugation process. BOC Sciences continuously optimizes conjugation processes using advanced technology platforms to ensure high conjugation efficiency and product consistency.
By combining two different toxins, dual payload ADCs can enhance therapeutic effects, overcome resistance, and reduce toxicity to normal tissues, thereby improving treatment safety and efficacy.

A dual-payload antibody-drug conjugate (Dual-payload ADC) is a targeted therapeutic carrier formed by combining an antibody with two drugs. The antibody portion specifically recognizes and binds to certain tumor cell surface antigens, delivering the drugs precisely to tumor cells. Compared to traditional single-drug ADCs, dual-payload ADCs carry two different therapeutic drugs (usually cytotoxic drugs) simultaneously, enhancing efficacy and overcoming tumor resistance.
A dual-payload ADC enhances efficacy by carrying two cytotoxic drugs that act on tumor cells through different mechanisms. One drug may target a specific cellular target, while the second drug complements or enhances its action, providing stronger anti-tumor effects. Additionally, dual-payload ADCs effectively overcome tumor cell resistance, increasing treatment success rates.
The advantage of dual-payload ADCs is their ability to deliver two different cytotoxic drugs simultaneously, which can enhance efficacy through complementary therapeutic mechanisms. Moreover, dual-payload ADCs minimize damage to healthy cells while maximizing treatment effects, reducing side effects. The multiple drug payloads also enable the ADCs to address tumor cell resistance.
Drug selection directly impacts the stability of dual-payload ADCs. Drugs must be stably conjugated to the antibody via an appropriate chemical linker to prevent premature release in the body. The chemical properties of the drug (such as solubility, molecular size, and lipophilicity) also affect its stability in the body. Choosing drugs with good biocompatibility and that can be effectively released in the tumor microenvironment is critical.
Dual-payload ADCs may increase toxicity risks because they carry two drugs, each of which could potentially cause side effects. However, through precise targeting design, dual-payload ADCs release the drugs within tumor cells, minimizing damage to normal cells. To reduce toxicity, the dosage, structure, and release mechanisms of the payloads need to be carefully optimized.
The key to optimizing the drug release mechanism of dual-payload ADCs lies in designing intelligent linkers that respond to tumor microenvironment characteristics (such as acidic or reductive conditions). Choosing linkers that precisely release the drug inside tumor cells or trigger drug release through tumor-specific enzymes can enhance efficacy and reduce damage to normal cells. Furthermore, the chemical stability and release rate of the drugs must be optimized to ensure the best therapeutic effect.
