Gaudi Cathedral, Barcelona

It seems oddly surreal of my photo editor to remind me that on this day in the past we were in Barcelona (right) for some conference or other and this year’s EORTC-NCI-AACR Molecular Targets meeting (aka the Triple in industry parlance) was cancelled in Spain in favour of a virtual meeting, thanks to the ongoing pandemic.

There is no doubt that thinking big in cancer research is vitally important, but sometimes we have to consider the difference between building cathedrals for the long-term rather than building simple walls as short-term fixes.

Here we consider some examples in the context of oncology drug development and also open the monthly October BSB mailbag…

To round off our series of post AACR reviews this week (there will be more coming next week as well, don’t worry), I wanted to look at some interesting non-immunotherapeutic agents that I found compelling and worth watching out for in the future.

A couple of things to remember or understand is that AACR is a very different conference from ASH and ASCO, aside from the presence of noticeably more science:

a) Much of the data presented at this meeting is either preclinical or phase I-II cinical data
b) Most of these studies are usually exploratory or preliminary in nature

Phase I trials are usually designed to evaluate dose finding in either a single agent or with an untested and untried combination. Investigators are interested in a number of key things here, which might include:

  • Maximum tolerated dose (MTD)
  • Dose limiting toxicities (DLT)
  • A recomemmended phase II dose (RP2D)
  • PK and PD
  • General tolerability assessment.

Sometimes a different formulation is tested, in which case bioavailabity is also important. To be expressly clear though – any efficacy signals seen are a bonus. That’s the main purpose of phase II trials.

That said, one of the things I most like about AACR is the early phase I data in new targets or data that explains why resistance develops as an adaptive response to therapy.  With these in mind, here are three excellent examples from well put together research from the meeting that we can learn a lot from.

DEDN6526A, a novel ADC in melanoma; AG–221 in IDH2 mutant AML and MDS; a PI3K-α isomer-specific inhitor, BYL719, and the impact of PTEN alterations
