More information
Many disease–relevant proteins are enzymes, transcription factors or part of signaling pathways and are located in the intracellular compartment. Small molecules have a great track record in interfering with intracellular target proteins and thereby execute a therapeutic effect. However, small molecules are mostly dependent on defined binding pockets in the target protein, limiting the druggable target space. In contrast, biologics, such as antibodies, can also bind with high affinity and specificity to planar target domains and thus can address different targets than small molecules. Unfortunately, biologics display poor cellular membrane permeability and cannot target intracellular proteins easily. Hence, technologies are required to deliver therapeutic proteins, such as antibodies intracellularly. Utilizing such delivery technologies opens up the intracellular target space for biologics and enables new therapies of diseases, in particular therapy of cancer.
The following potential approaches to answer our question include, but are not limited to, the following:
- Delivery technologies that are ideally based on proteins, peptides, or antibodies.
- Delivery technologies that fit to industry standard biologics manufacturing platforms.
- Technologies that deliver therapeutics to tissues at a concentration that is therapeutically relevant and potentially scalable to human use.
- Delivery technologies that are able to direct cargo to specific subcellular compartments, including the nucleus.
- Delivery technologies that rely on nanoparticles or dendrimers are not the primary focus of this call but would be considered.
Of note for this question:
- Delivery technologies, which enable tumor cell/tissue specific redirection of the biologic in addition to intracellular delivery, are preferred.
- Proposals including data on in vivo proof of concept are preferred.
- Proposals that rely on specific formulations using exosomes or liposomes.
- Proposals that rely on viral delivery based technologies
We are open to all proposals that can fully or partially meet our requirements.
If your project is selected, you will have the opportunity to directly collaborate with the Biotherapeutics Discovery Research (BTD) team of Boehringer Ingelheim. You can expect appropriate funding for the prospective collaboration period. Your exact funding request should be outlined in your proposal. As a framework, we suggest that your initial funding request is clearly structured in milestones including proposed Go/ No-Go criteria. Ideally, the initial milestones resulting in Go/No-Go decisions will not exceed 200,000 euros per submitted project in total. Please note that additional budget will be made available if the milestones and Go decision points are met. We set ourselves the goal to complete all evaluations within four weeks after the deadline of the submission period (i.e. evaluation feedback by end of November 2020).
The opportunity for a funded stay at Boehringer Ingelheim for technology exchange / training is potentially available, as is the availability of custom biological tools and reagents. It is also possible to run specific experiments at Boehringer Ingelheim.
Our collaboration agreement will provide full transparency about each partner’s rights & obligations (including intellectual property rights). As part of the agreement, you will be encouraged to publish following the collaboration agreement (to be negotiated in good faith). There is also the possibility to chose the name of the technology.
In order to foster the highest degree of open innovation possible, we plan to announce the winner(s) publically and feature them on opnMe.com and our social media channels. We would guide you through this process and, as part of it, we would kindly ask for your upfront consent, in case our scientific jury had selected your answer. An alignment on a common communication strategy is supported.
We are seeking research collaboration proposals that contain:
- A well-structured proposal outlining a new and compelling scientific idea,
- A novel, testable working hypothesis distinct from those previously published,
- A well-structured experimental plan that will be used to test the hypothesis, and potentially existing data,
- Inclusion of key decision points [Go/No-Go criteria] and a milestone plan including an outline about budget requirements for the work until the first Go/No-Go milestone step,
- Proven track record in the required field of expertise,
- Outlining the technical feasibility of the innovative proposed approach,
- Ability to implement the outlined solution as part of a scientific collaboration project including access to a laboratory.
Please use our answer submission template to provide a 2-3 page non-confidential proposal (available for download here).
If confidential data exists that would strengthen the proposal, please indicate that confidential information is available to share under a Confidential Disclosure Agreement (CDA). If we find the non-confidential concept proposal sufficiently interesting, we will execute a CDA for confidential discussions.
We have been looking for answers for the following scientific challenge: How would you propose to deliver therapeutic proteins such as antibodies intracellularly?
All incoming answers accompanied by a collaboration proposal will be evaluated by a scientific jury, and, upon selection, chosen proposals are pursued through a joint collaboration with the successful applicants. Initial funding of up to 200,000 euros will be available for each selected proposal.
We can only accept research proposals if they arrive by the submission deadline on October 29, 2020, 11.59 pm PST.
