Safety and Tolerability of Antibody-Drug Conjugates in Cancer.

Antibody-drug conjugates are monoclonal antibodies attached to biologically active drugs through chemical linkers that deliver and release cytotoxic agents at the tumor site, reducing the likelihood of systemic exposure and therefore toxicity. Currently, there are about 110 ongoing studies implementing antibody-drug conjugates in the treatment of multiple human malignancies. Antibody-drug conjugates carry a feature of the specificity of a monoclonal antibody and the anti-neoplastic potential of a cytotoxin....

Antibody-Drug Conjugates for the Therapy of Thoracic Malignancies.

Antibody-drug conjugates are a novel class of therapeutic agents incorporating both target-specific monoclonal antibodies and cytotoxic small molecules via a chemical linker. They were first introduced into the clinic for the treatment of advanced hematologic malignancies. The only approved antibody-drug conjugate for solid tumors targets HER2, a validated antigen in breast cancer. Many antibody-drug conjugates are under active investigation for various types of solid tumors. In this article, we review the ...

Uncialamycin as a novel payload for antibody drug conjugate (ADC) based targeted cancer therapy.

Uncialamycin analogs were evaluated as potential cytotoxic agents in an antibody-drug conjugate (ADC) approach to treating human cancer. These analogs were synthesized using Hauser annulations of substituted phthalides as a key step. A highly potent uncialamycin analog 3c with a valine-citrulline dipeptide linker was conjugated to an anti-mesothelin monoclonal antibody (mAb) through lysines to generate a meso-13 conjugate. This conjugate demonstrated subnanomolar potency (IC50 = 0.88 nM, H226 cell lin...

An Alternative Focus for Route Design for the Synthesis of Antibody-Drug Conjugate Payloads.

An analysis of Antibody-Drug Conjugate Payload manufacturing has revealed that the majority of the cost is associated with the use of high-containment facilities for the latter stages of the synthesis. To make a significant reduction in the Cost of Goods (CoGs), a new approach to route design has been introduced which focusses on minimizing the number of steps that require high-containment. This approach has been exemplified in a new synthesis of tesirine, including the first application of a ring-closing c...

PDL-1 Antibody Drug Conjugate for Selective Chemo-Guided Immune Modulation of Cancer.

Targeting immune checkpoint molecules such as programmed death ligand-1 (PDL1) is an emerging strategy for anti-cancer therapy. However, transient expression of PDL1 and difficulty in tumor stroma penetration has limited the utility of anti-PDL1 therapy. To overcome these limitations, we report a new conjugate between the clinically approved PDL1 antibody (PDL1 AB) and drug Doxorubicin (Dox), named PDL1-Dox. We conjugated PDL1-Dox through a hydrazone linker containing a polyethylene glycol (PEG) spacer, whi...

A single dose of antibody-drug conjugate cures a stage 1 model of African trypanosomiasis.

Infections of humans and livestock with African trypanosomes are treated with drugs introduced decades ago that are not always fully effective and often have severe side effects. Here, the trypanosome haptoglobin-haemoglobin receptor (HpHbR) has been exploited as a route of uptake for an antibody-drug conjugate (ADC) that is completely effective against Trypanosoma brucei in the standard mouse model of infection. Recombinant human anti-HpHbR monoclonal antibodies were isolated and shown to be internalised i...

Antibody-drug therapeutic conjugates: Potential of antibody-siRNAs in cancer therapy.

Codelivery is a promising strategy of targeted delivery of cytotoxic drugs for eradicating tumor cells. This rapidly growing method of drug delivery uses a conjugate containing drug linked to a smart carrier. Both two parts usually have therapeutic properties on the tumor cells. Monoclonal antibodies and their derivatives, such as Fab, scFv, and bsAb due to targeting high potent have now been attractive candidates as drug targeting carrier systems. The success of some therapeutic agents like small interferi...

Miniaturised 'antibody'-drug conjugates for solid tumours?

With Antibody-Drug Conjugate strategies firmly focussed on the precise conjugation to the large protein Immunoglobulin-G format, it is easy to miss the more recent technological innovations in small-format drug conjugates. Here, the targeting ligand can be at 50-95% reduced in size, or even smaller if peptidic in nature. Antibody domains or alternative binding scaffolds, chemically-modified with ultra-potent cytotoxic payloads offer an alternative approach for oncology therapeutics, promising a wider therap...
