@Bella, the answer is lack of funds to pursue all the possibilities in-house. Which is why there is only ONE new candidate in the pipeline - AVA6103.
Avacta will take AVA6000 to regulatory approval for STS and/or SGC and hope to license it out for triple negative breast cancer.
Avacta hope that AVA6103 will be licensed out for breast cancer and gastric, lung, pancreatic and possibly other cancers - all diseases that are big markets, so attractive to big farmer, but would require multiple, multiple clinical trials for combination therapies if AVA6103 monotherapy proves not to result in 100% remission.
There are also possibly other candidates with payloads in the AVA6100 series. AVA6103 is the third numbered candidate in the series. The others may have exatecan (with different capping group and/or self-immolative linker) and certainly other warheads as their payload. Unless Avacta identifies one suitable for development and has the funds available by that time to take it to market, then these will all be available for licensing.
The AVA7100 series, the AffDCs, are a whole new ball game, but very early days still. No individual drug candidate(s) have been identified yet (that we know of).
