Bayer HealthCare

For many types of cancer classic chemotherapy is often the only form of treatment available. It functions on the basis of a cytotoxic effect – a cytotoxin kills cancer cells, halting tumor growth. However, these drugs also damage healthy cells and patients may, as a result, suffer severe side effects. With modern cancer therapies physicians are able to target the cancer more precisely.

They include the recently developed approach of antibody-drug conjugates (ADC). This new approach attacks the cancer in a much more targeted way and healthy cells are less severely affected.

Bayer HealthCare currently has several projects using this approach in its research pipeline. The company has the worldwide rights to utilize Seattle Genetics’ auristatin-based ADC technology with antibodies to several oncology targets.

Bristol Myers Squibb's (BMS)

Bristol Myers Squibb’s (BMS) oncology R&D pipeline of about 20 compounds in development represents a wide range of proven and potential treatment platforms, including traditional cytotoxins as well as biologics, immunotherapies and other novel and targeted approaches such as Antibody-drug Conjugates (ADCs) in which a cancer-killing drug is linked to a monoclonal antibody. The antibody specifically targets a particular cancer cell antigen, thus ignoring most normal cells and delivering the drug directly to the cancer cell.

The company is conducting about 200 oncology clinical trials, addressing 20 different tumor types. Among the most exciting areas of research is immuno-oncology. Bristol-Myers Squibb’s work in the field of immuno-oncology began in the mid-1990s, and picked up momentum in 2005 when the company formed a collaborative alliance with Medarex Inc, a biotechnology company now owned by BMS and based in Princeton, New Jersey. BMS acquired Medarex in August 2009 and assumed full rights to ipilimumab – an investigational, naked, therapeutic antibody in late-stage development for metastatic melanoma which the FDA approved in March 2011 as Yervoy, and other early-stage investigational cancer compounds.  As a result, the company is positioning itself for long-term leadership in this area.  A clinical Phase I trial (NCT00944905) with BMS’s lead ADC candidate, MDX-1203, a duocarmycin-based toxin conjugated to an anti-CD70 Medarex antibody was recently completed. The purpose of this study was to determine if MDX-1203 is safe for the treatment of renal cell carcinoma or non-hodgkin’s lymphoma.

Celldex Therapeutics

Celldex Therapeutics  was founded based on a fundamental scientific belief that harnessing the power of the immune system would break significant barriers in drug development for a host of devastating diseases. The Company’s pipeline is comprised of therapeutic antibodies, antibody drug conjugates, immune system modulators and vaccines that we believe have a higher probability of success because they are targeted to specific patient populations with high unmet medical need whose diseases express specific markers—including many underserved or completely un-served orphan indications. This has created a leading pipeline in immunotherapy comprised of two candidates in pivotal trials, one in brain cancer and one in triple negative breast cancer, four additional clinical candidates in a range of difficult-to-treat indications and a robust preclinical engine.

Many of Celldex’ clinical programs seek to leverage the power of the immune system’s response by combining therapeutic approaches to maximize their potential. Key to this strategy is our ability to understand our own asset base while also identifying promising external technologies that will complement it.

In 2005, Celldex was spun out of the New Jersey based biopharmaceutical company Medarex (now a subsidiary of the Bristol-Myers Squibb Company) and, in connection with this transaction, Celldex retains the rights to obtain exclusive commercial licenses to proprietary monoclonal antibodies raised against certain antigens utilizing the Medarex UltiMAb technology platform. Since its inception, Celldex has also acquired four companies, folding in three assets, and in-licensed/purchased an additional two assets. With the potential for positive results in ongoing late stage programs, the next stage in Celldex’s development is to become a fully-integrated commercial entity.

Concortis Biosystems

Concortis Biosystems, Corp is a biotechnology company creating next generation biotherapeutics using proprietary conjugation technologies and novel drug delivery systems, including antibody-drug conjugates (ADCs). ADCs are a new type of targeted therapy. They covalently connect potent cytotoxic drugs (referred as toxins) to an antibody or antibody fragment via chemical linkers, providing a means to increase the effectiveness of chemotherapy by targeting the drug to cancer cells while reducing side effects. The antibody in use directs the ADC to bind to the target cancer cells, and then delivers the ADC to lysosome by receptor-mediated endocytosis, where the drugs are released to kill the cancer cells. The therapeutic index will be expanded because of the targeting effects

Linkers are designed to allow ADCs to remain inactive while in circulation, and should be readily cleavable once inside the target cells. Concortis’ miniPEG-based hydrophilic linkers help prevent the drug being pumped out of resistant cancer cells through MDR (multiple drug resistance) transporters.

Internalization and affinity of the mAb, linker stability, and potency of the cytotoxic are all key considerations when optimizing and developing an ADC. Over the past years, Concortis has developed diverse classes of cytotoxic drugs and linkers that are ready to empower therapeutic antibodies and to achieve synergistic effects.

Traditional cytotoxic cancer chemotherapies kill rapidly dividing cancer and normal cells in an indiscriminate manner.  this leads to significant toxicity in patients being treated. In response to this limitation, a number of targeted therapies were developed to be more selective, including monoclonal antibody-based therapies. For certain cancers, antibodies alone are not sufficiently effective to achieve meaningful clinical benefit. This limitation has led to the development of a new class of agents called antibody drug conjugates or ADCs.  These ADCs are comprised of a monoclonal antibody, which is used to target the specific cancer, attached via a linker system to a cell-killing drug.

Endocyte’s proprietary technology platform to create novel small molecule drug conjugates or  SMDC represents a new approach, comparable to ADCs, in its ability to deliver highly active drug payloads in a targeted manner.  Endocyte’s SMDCs actively target receptors that are over-expressed on diseased cells, relative to healthy cells. This targeted approach is designed to enable the treatment of patients with highly active drugs at greater doses, delivered more frequently, and over longer periods of time than would be possible with the untargeted drug alone.

The company is also developing companion imaging diagnostics for each of the SMDCs they are developing.  These diagnostic tools are designed to identify patients whose disease over-expresses the target of the therapy and who are therefore more likely to benefit from treatment. This combination of an SMDC with its companion imaging diagnostic is designed to personalize the treatment of patients by delivering effective therapy, selectively to diseased cells, in patients most likely to benefit.

Researchers expect that Endocyte’s  SMDC technology platform offers a number of potential advantages:

  • Small size to better penetrate solid tumors
  • Rapid clearance for reduced toxicity
  • Companion imaging diagnostics for targeted therapy
  • Cost-effective and simple to manufacture

Antibody drug conjugates (ADCs) are formed by attaching drug substances to antibodies using a special linker moiety. The ideal ADC will specifically target antigen-expressing cells and release the drug in active form inside the cell. ADCs combine the specificity of monoclonal antibodies with high potency of cytotoxic drugs, leading to highly improved therapeutic efficacy and less side effects. However, the current challenges in ADC technology are related to creating highly homogeneous ADC products with high drug-to-antibody ratio as well as applying the technology to various drug substances.

Glykos focuses on discovery and development of products and technologies which are based on bioactive glycans. The company’s ADC technology includes novel linker technology and cytotoxic drug derivatives which overcome several limitations of current ADC applications. The key benefits of Glykos’ technology include flexible optimization of the hydrophilic character of the drug component using the company’s linkers and the ability to site-specifically conjugate practically any monoclonal antibody with the client’s toxin of choice.

Other benefits include homogeneous drug-to-antibody ratio (DAR) and significantly improved payload efficacy particularly against drug-resistant cells and low-abundance target antigens.

Glykos’ linkers can be used with practically any monoclonal antibody and with a large selection of potent toxins making our technology highly flexible as it can be integrated into clients existing development programs.

The company’s services are characterized by a high degree of flexibility, rapid turn-around and consistent high quality.

Heidelberg Pharma’s own R&D flagship is its proprietary 2nd generation ADC technology for more effective anti-cancer drugs. The company has developed a new ADC technology based on the most potent RNA-polymerase II inhibitor amanitin, a bicyclic octapeptide isolated from the Green Deathcap mushroom Amanita phalloides.

Amanitin interferes with the eukaryotic transcription process at very low intracellular concentrations, making it an ideal drug for the use with antibodies binding at low-copy number antigens.

Heidelberg Pharma and its cooperation partners have shown outstanding activity of amanitin-based ADCs in therapy-resistant tumor cells, e.g. cells expressing multi-drug resistant transporters, tumor-initiating cells and non-dividing cells at picomolar concentrations. The tolerability and therapeutic window of amanitin-ADCs has been determined in different rodent and non-human primate models. Furthermore, amanitin has a water-soluble structure, resulting in ADCs with low tendency for aggregation, even using higher DAR (Drug to Antibody) ratios.

Igenica, a biopharmaceutical company founded in 2009, focuses on the development of antibody-based therapies for the treatment of patients with cancer.

Although recombinant monoclonal antibodies (mAbs) are considered to be one of the most promising reagents for immune-based cancer therapy, relatively few products have been approved for use in humans. In fact, there appears to be an increasing reliance on an overlapping portfolio of mAb drugs and drug targets, discovered by a process that has evolved very little over the past two decades. Igenica contends that the key to next generation mAb-based medicines lies in both the identification of new targets and the deployment of novel antibody discovery approaches.

To this end, the company has developed two unique technology platforms that collectively offer a function-orientated screening strategy to systematically discover new tumor antigens and effective antibody drug candidates. The first platform, sTAg (surface-tagged antigen profiling), is an innovative proteomics-based technology designed to identify new surface antigens that are amenable to antibody targeting in cancer settings. The second platform, iTAb (in vivo anti-tumor antibody screening), is a monoclonal antibody discovery platform which provides a function-based,in vivo methodology for screening monoclonal antibody drug candidates against newly discovered antigens that are effective in eliminating or controlling cancer.

Intellect Neurosciences

Intellect Neurosciences, Inc. develops innovative approaches aimed at arresting or preventing Alzheimer’s disease and other neurodegenerative diseases, with a specific focus on proteinopathies. Intellect’s pipeline includes therapeutic vaccines, antibodies and neuroprotective antibody drug conjugates (ADCs).  Intellect’s flagship CONJUMAB platform empowers monoclonal antibodies targeting amyloidogenic proteins with additional neuroprotective properties by combining them chemically with a small molecule such as an antioxidant.

The company’s ADC- based technology has the potential to improve on current methods of passive immunotherapy by increasing clearance of amyloid proteins while delivering potent cytoprotective molecules to sites of damage in the brain and other organs.  CONJUMAB-A, the first compound from this platform, is designed to reduce inflammation caused by amyloidosis while avoiding vasogenic edema, a side effect of plaque dissolution that occurs in some patients.

The company’s lead CONJUMAB-A candidate is IN-N01-OX2, a non-activating, stabilized IgG4 humanized antibody specific for beta amyloid protein conjugated to melatonin, which is a naturally occurring molecule with potent anti-oxidant and anti-fibrillogenic properties.

Beta amyloid, when it accumulates in the retina of the eye, causes damage by oxidative stress. The conjugate is anticipated to increase the therapeutic window for melatonin to protect retinal epithelial cells, promote clearance of beta-amyloid away from sites of damage and limit potential off-target side-effects.

CONJUMAB-A may also have potential applications for diabetic retinopathy, glaucoma, traumatic brain injury, and Alzheimer’s disease.

Antibody-drug Conjugates (ADCs) are expected to be the next generation of antibody therapeutics. Current unmodified monoclonal antibodies (MAbs) do not cure, and can only extend survival by 5-6 months. In addition, many antibodies suffer from drug resistance due to mutations in cell-signalling pathways. The main method for conjugating drugs to MAbs has been via the thiol side-chains of cysteine residues (Cys-SH). Though affording a certain degree of stoichiometric control during conjugation, this protocol yields only low drug-loading ratios, due mainly to the large Mab-drug conjugate becoming notoriously insoluble at higher drug loadings.

With its proprietary OptiLink technology platform, PhotoBiotics has adopted an altogether more novel approach using much smaller antibody fragments (scFvs) that are relatively easy to bioengineer with lysine residues for multiple drug-molecule conjugation to their -NH2 side-chains. Quite counter-intuitively, this approach provides far higher drug loadings than have so far been achieved with whole MAbs, without running the risk of drug-scFv-conjugate insolubility. This provides:

  • Applications in both therapy and diagnostic imaging
  • ‘See & Treat’ as a time-saving and therapeutically enhancing opportunity

Quanta BioDesign, Ltd

Quanta BioDesign, Ltd.  in was founded 1997 for the purpose of developing and commercializing an extensive line of products for companies involved in drug discovery and diagnostic development programs.  The company’s products are based on  proprietary discrete polyethylene glycol (dPEG®) chemistries, including a the processes for making these compounds.  The single molecular weight ethylene glycol conjugation technology, dPEG eliminates common problems found in the development of diagnostic and therapeutic products, such as aggregation and non-specific interactions, poor water solubility, poor delivery, delivery issues/options, short serum half-life, toxicity and antigenicity.

Like traditional PEGs, Quanta BioDesign’s products contain a hydrophilic, water-soluble backbone consisting of repeating ethylene oxide units. However unlike traditional PEGs each of the company’s products represents a single compound with a unique, specific, single molecular weight (MW).  Quanta BioDesign’s products are synthesized from pure building blocks (e.g. triethylene glycol or tetraethylene glycol) in a series of step-wise reactions to provide specific MWs, architectures, functional groups, and organic moieties suited for a wide variety of applications. These products have now been used for the modification of therapeutic macromolecules, as linkers in antibody-drug conjugates (ADCs), for bioconjugation of biologics, for surface modification, and in diagnostics.

Sorrento Therapeutics

Sorrento Therapeutics is developing Antibody Formulated Drug Conjugates or AfDC technology as foundation for next-generation antibody-drug conjugates (ADCs), a promising drug class that combines specific tumor targeting with the delivery of potent oncolytic therapeutics. As foundation for our AfDC, Sorrento acquired IG-004 (formerly known as TOCOSOL™-paclitaxel), a tocopheryl polyethelyene glycol succinate (“TPGS”)-based drug formulation from IGDRASOL. IG-004 has been clinically-validated and completed Phase II trials in NSCLC, pancreatic cancer, ovarian cancer, colorectal cancer and bladder cancer as well as completed Phase III studies in MBC in the US and/or ex-US.

While ADCs are an improved therapeutic approach to combat cancer, current ADC technology has limitations, such as required prodrug synthesis, development of linker and drug release strategies, potential systemic toxicities upon premature drug release and requirement of ADC internalization into the tumor cell for efficient anti-cancer effect.

These bottlenecks are addressed by our proprietary AfDC technology, including rapid generation of AfDC therapeutics, greater flexibility for mAb-drug combinations, targeting of the tumor site rather than individual cancer cells, higher avidity for target cells via multiple antibody molecules per AfDC, and potentially increased cytotoxic payload including delivery of one or more distint oncolytic drugs into the tumor.

The significant therapeutic promise of ADCs, together with increasing biopharma interest in ADC-type technologies and a validated regulatory approval pathway, create an exciting opportunity for developing improved, next-generation AfDC candidates.

Sutro’s cell-free expression technology provides a rapid and powerful platform for the discovery and development of next generation antibody-drug conjugates (ADCs).

Current ADCs in development have immense promise, but they are limited by the fact that they are structurally heterogeneous populations in which the position and number of conjugated linkers and warheads vary significantly. Such heterogeneity prevents the definition of structure-activity relationships (SARs). Consequently, using traditional ADC technologies prevents researchers from discovering and developing candidates with optimal therapeutic indices and can result in products with unpredictable and sub-optimal pharmacokinetic properties, stability and efficacy.

Sutro can incorporate non-natural amino acids (nnAA) at any site in an antibody structure, thereby allowing for single-species ADCs with site-specific conjugation of linker and warhead. Of vital importance in this process is Sutro’s ability to perform rapid and parallel synthesis of numerous variants taking advantage of a substantial number of different sites, enabling analyses early in discovery to define SARs and locate the best positions for nnAA incorporation based on:

  • Protein expression levels
  • Efficiency of incorporation of the nnAA
  • Linker / warhead conjugation efficiency
  • Target binding efficiency
  • Cell killing efficiency
  • Internalization characteristics

It has been well documented that the cell-killing effects of ADCs are highly dependent on the location of the warhead as well as the drug to antibody ratio. Sutro can control both of these variables with exquisite specificity, resulting in truly optimized product candidates.

Sutro has also addressed the challenge of manufacturing nnAA-containing ADCs by engineering additional versions of cell-free extract that achieve high rates of incorporation of nnAAs and by developing chemistries that allow for efficient conjugation of linkers and warheads to antibodies.

Tagworks Pharmaceuticals

Tagworks Pharmaceuticals is developing a unique approach towards antibody-based imaging and therapy. Tagworks’ technology enables the actuation of tagged antibodies through selective chemical manipulation in vivo, improving the efficacy of established approaches such as Radioimmuno-imaging and –therapy and Antibody-Drug Conjugates (ADCs).

ADCs are highly potent biopharmaceuticals that use the targeting ability of monoclonal antibodies (mAbs) to selectively bind to tumor cells where the conjugated cancer drug is released. The antibody and the small molecule drug are bound by a linker. Only when the linker is cleaved do these cell-killing drugs become active. This generates an excellent control mechanism of drug activation, allowing an increase of the therapeutic window and thereby the use of highly potent drugs. Current ADC technologies rely on biological cleavage of the linker. The ADC has to bind to a tumor cell-specific membrane receptor and subsequently be internalized in the tumor cell for cleavage of the linker – and thus activation of the drug – to occur. As the number of tumor-specific receptors that ensure efficient internalization is limited, especially in solid tumors, a wide range of cancer-targets remains out of reach of ADCs.

Tagworks tackles this problem by focusing on chemically triggered release mechanisms for ADCs. Recently, the company succeeded in modifying the fastest and highly selective click reaction, the inverse-electron-demand-Diels-Alder reaction, in such a way that we achieved selective bioorthogonal release. An unprecedented approach that holds great promise for employing chemically triggered release of a drug from a tumor-bound ADC. This would mean a substantial expansion of the scope of suitable ADC targets to include for example slow- or non-internalizing targets and extracellular-matrix constituents that are not suitable for biological cleavage mechanisms.

Tagworks Pharmaceuticals is a privately held pharmaceutical company based in Eindhoven, The Netherlands, focused on the in vivo assembly and actuation of diagnostic and therapeutic antibody conjugates. Founded in 2011, Tagworks is a spin-out of Royal Philips Electronics, and originates from Philips’ molecular imaging expertise.

The company’s is headquartered at the High Tech Campus in the Center for Imaging Research and Education (CIRE), which is a shared life science facility between Philips, the Technical University Eindhoven, and third parties.

ThioLogics is a new biotechnology company that has developed a groundbreaking site-specific conjugation platform that will enable the assembly of the next generation of antibody-drug conjugates or ADCs.

Based on propriety chemistries arising from the laboratories of its University College London founders, Professor Stephen Caddick and Dr. James Baker, Thiologics has developed a conjugation platform that allows the selective, stable and functional modification of disulfide bonds or free cysteine in peptides, proteins and antibodies.

ThioLogics groundbreaking conjugation platform allows the selective, stable, functional modification of disulfide bonds or free cysteine in proteins and peptides. Technology that will allow versatile modification of proteins to yield well-defined, homogeneous products is highly desirable. In particular, it has been demonstrated that homogeneous ADCs have a greatly improved therapeutic index over analogous heterogeneous formulations. Introducing greater homogeneity into protein conjugates will also greatly simplify process and development issues, thus reducing costs.

The ThioLogics conjugation platform is being exemplified for a range of modalities across the biologics sector. These include: (i) peptide and protein therapeutics, (ii) the creation of stable and simple to manufacture bispecific antibodies, and (iii) the development of stable and homogenous antibody-drug conjugates for full antibodies and antibody fragments.
