Our Pipeline

A robust pipeline of ADCs intended for the treatment of hematological cancers and solid tumors

ADC Therapeutics is advancing a portfolio of investigational ADCs including those which utilize our highly potent pyrrolobenzodiazepine (“PBD”) technology, a differentiated exatecan-based payload with a novel hydrophilic linker and a next generation ADC toolbox.

Pre-clinical candidates targeting Claudin-6, NaPi2b, PSMA and ASCT2 are based on an innovative proprietary approach which utilizes exatecan with a novel hydrophilic linker as a highly potent and differentiated payload.

By leveraging decade-long expertise in the ADC field with multiple INDs and a proven track record of success, ADC Therapeutics continues building this toolbox with new antibody formats, linkers and toxins while advancing a range of payloads, linkers and conjugation technologies against multiple targets to develop differentiated next-generation assets.

The agents represented in this pipeline chart are investigational. Efficacy and safety have not yet been established.

Loncastuximab tesirine-lpyl

Loncastuximab tesirine-lpyl is an ADC composed of a humanized monoclonal antibody that binds to human CD19 and is conjugated through a linker to a PBD–dimer toxin. Once bound to a CD19-expressing cell, loncastuximab tesirine-lpyl is internalized into the cell, where enzymes release the PBD-based warhead. The warhead is designed to bind irreversibly to DNA to create highly potent interstrand cross-links that block DNA strand separation, thus disrupting essential DNA metabolic processes such as replication. This ultimately results in cell death.

ADCT-602 targeting CD22

ADCT-602 is an ADC composed of a monoclonal antibody that binds to CD22 conjugated to a PBD–dimer toxin. Once bound to a CD22-expressing cell, ADCT-602 is internalized into the cell where enzymes release the PBD-based warhead. CD22 is an attractive and clinically validated ADC target. CD22 is highly expressed on most malignant B-cells, including expression in more than 90% of patients with B-cell acute lymphoblastic leukemia (ALL).

ADCT-602 is being evaluated in a phase I/II clinical trial in patients with relapsed or refractory B-cell ALL (NCT03698552). The trial is being led by The University of Texas MD Anderson Cancer Center.

Mipasetamab uzoptirine (ADCT-601)

Mipasetamab uzoptirine (ADCT-601) is an ADC composed of a humanized monoclonal antibody that binds to human AXL (licensed from BerGenBio), conjugated using GlycoConnect™ technology (licensed from Synaffix BV) to a linker with the PBD–dimer toxin SG3199. Once bound to a cell that expresses the AXL protein, Mipasetamab uzoptirine (ADCT-601) is internalized, the PBD is released and diffuses into the nucleus where it binds the DNA. AXL is a promising target for an ADC approach, as it is overexpressed in many solid tumors (e.g., sarcoma, lung, breast, prostate, pancreas, glioma, and esophageal) and hematological malignancies (e.g., acute and chronic myeloid leukemia).
