About AFM13

AFM13 is a first-in-class innate cell engager (ICE) that uniquely activates the innate immune system to destroy CD30-positive hematologic tumors. AFM13 induces specific and selective killing of CD30-positive tumor cells, leveraging the power of the innate immune system by engaging and activating natural killer (NK) cells and macrophages. AFM13 is Affimed’s most advanced ICE clinical program and is currently being evaluated as a monotherapy in a registration-directed trial in patients with relapsed/refractory peripheral T-cell lymphoma or transformed mycosis fungoides (REDIRECT). The study is actively recruiting, and additional details can be found at www.clinicaltrials.gov using the identifier NCT04101331.

In addition, Affimed is studying AFM13 in combination with cord blood-derived allogeneic NK cells in patients with recurrent or refractory CD30-positive Hodgkin or non-Hodgkin lymphomas. The investigator-sponsored Phase 1 study, conducted at the MD Anderson Cancer Center in Houston, is administering a CAR-like, stable complex of AFM13 pre-loaded cord blood-derived allogeneic NK cells. The study can be found at www.clinicaltrials.gov using the identifier NCT04074746.

About AFM24

AFM24 is a tetravalent, bispecific innate cell engager (ICE) that activates the innate immune system by binding to CD16A on innate immune cells and EGFR, a protein widely expressed on solid tumors, to kill cancer cells. Generated by Affimed’s fit-for-purpose ROCK platform, AFM24 represents a distinctive mechanism of action that uses EGFR as a docking site to engage innate immune cells for tumor cell killing through antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis.

Affimed is evaluating AFM24 as a monotherapy for patients with advanced EGFR-expressing solid malignancies whose disease has progressed after treatment with previous anticancer therapies. AFM24-101 is a first-in-human Phase 1/2a open-label, non-randomized, multi-center, multiple ascending dose escalation and expansion study and can be found at www.clinicaltrials.gov using the identifier NCT04259450. In addition, Affimed is planning to initiate further studies evaluating AFM24 in combination with adoptive NK cell transfer and in combination with atezolizumab.

The accepted research describes multiple aspects of validation for the unique mechanisms of these therapies in development for treating a wide range of tumor types.

Accepted abstract titles include:

MP0317 (targeting CD40 and FAP)
MP0317, a FAPxCD40 targeting multi-specific DARPin therapeutic, drives immune activation and leads to macrophage repolarization in vitro and ex vivo
T-cell engager programs
Novel multi-specific DARPin T-cell engager with an improved therapeutic window to overcome dose limiting toxicities in AML therapies.
A solution to T-cell engager toxicity: An anti-CD3 Prodrug DARPin (CD3-PDD) shows no toxicity, but potent anti-tumor activity in a humanized mouse model
Peptide-MHC program
Application of the DARPin technology for specific targeting of tumor-associated MHC class I: peptide complexes
For MP0317, the company’s multi-specific DARPin candidate targeting both FAP and CD40 to enable tumor-localized immune activation, the research describes how the candidate’s activation of immune cells in-vitro, as well as on human tumor samples, was dependent on the presence of the FAP protein, which is highly expressed in the stroma of a broad range of solid tumors. Furthermore, the research observed that immunosuppressive macrophages associated with tumor growth and spread were reverted by MP0317 into an anti-tumor phenotype. These data support MP0317’s potential to deliver tumor-localized CD40-mediated immune cell activation avoiding systemic toxicity seen in other agents. MP0317 is anticipated to begin clinical trials in the second half of 2021.

For the T-cell engager program, two accepted research abstracts detail the construction of next generation T-cell engager DARPin molecules designed to overcome the limited tumor specificity and the immune hyperstimulation associated with other T-cell engager approaches. By linking a T cell engaging CD3 DARPin binder to additional DARPin binder domains that optimally engage tumor-specific antigens in parallel, the company generated candidates that displayed strong in vitro potency, and low levels of cytokine release ex vivo – suggesting low systemic immune activation. Furthermore, an anti-CD3 Prodrug DARPin (CD3-PDD) was successfully designed to have its immunostimulatory effects inactivated by a linked ‘blocking’ DARPin domain, and become activated only in the tumor microenvironment, upon cleavage of the linker by tumor-associated proteases. In an in vivo humanized mouse tumor model, this candidate demonstrated anti-tumor activity and no toxicity when administered systemically. Together, the research supports Molecular Partners’ DARPin technology ability to control immunostimulation through a validated mechanism with a heightened level of precision relative to existing approaches.

Finally, for the peptide-MHC (pMHC) program, the research provides updates on the development of pMHC binders in the T cell engager format. The successful screening and engineering of the bispecific DARPin candidates (pMHC-CD3) achieved highly potent and specific T cell activation only in the presence of the target peptide, resulting in T-cell mediated tumor cell killing. A vast majority of tumor or viral antigens are presented as peptides on the cell surface by MHC molecules for immune cell recognition and have potential to be leveraged as versatile targets for immunomodulating therapeutics. However, to-date, antibody and T-cell receptor-based pMHC binders have been challenged by their low target abundance, weak affinity, cross-reactivity to other pMHCs, or challenging biochemical properties.
