Key takeaways

  • The Lopker Family Foundation funds translational cancer research that moves promising laboratory discoveries toward first-in-human clinical trials, so a nonprofit whose work sits outside that area is unlikely to fit.
  • The foundation describes its partners as public universities whose cancer research centres are NCI-designated comprehensive cancer centres, and it prioritises institutions that lead in innovation despite smaller unrestricted endowments, so an organisation that is not such an institution should check its fit before writing in.
  • Half of its grants to organisations were $10,000 or less, so a modest request is the realistic starting point, although one award of $1,000,000 appears above its stated $200,000 to $300,000 grant range.
  • The filing shows that 92% of its grant dollars went to organisations it had also funded in an earlier filing, so this looks like a relationship-led funder, and a first approach should be a letter naming the organisation and grant purpose, with a copy of its federal tax-exemption letter.
  • The filing gives no deadlines, so no set date for applications is stated.

Priority Areas

The Lopker Family Foundation funds translational cancer research, aiming to move promising laboratory discoveries through the gap between academic discovery and first-in-human clinical trials. Its support covers safety and efficacy studies, pre-IND and IND regulatory milestones, clinical readiness, novel drug combinations and breakthrough diagnostics. It partners with public universities whose cancer research centres are NCI-designated comprehensive cancer centres, prioritising institutions that lead in innovation despite having smaller unrestricted endowments than their private counterparts. Projects are vetted by a board of volunteer scientists for technical merit and clinical viability. The foundation seeks to maximise capital working in the lab to bring cancer cures to market quickly.
