A new generation of linkers, developed independently by ImmunoGen and Seattle Genetics, two American firms, are robust enough to hold the drug in the bloodstream and release it only when the ADC reaches the tumour cells.Last year the FDA approved the first of this new crop of ADCs, Seattle Genetics Adcentriss, for the treatment of two types of lymphoma.
In practice, though, deploying them in cancer therapy has proved tricky.Dr Blackwell and her team tested an ADC called trastuzumab emtansine (or T-DM1 for short).
The ADC indeed triggered fewer complications than the standard treatment did, though it failed to eliminate them completely.
Mylotarg, the first ADC therapy approved by America's Food and Drug Administration FDAA), had to be withdrawn from the market last year because its linker released the drug in the patient's bloodstream, making it no better and possibly worse than standard chemotherapy.

Three non-governmental organisations (NGOs) - Alburnus Maior, the Independent Center for the Development of Environmental Resources, and Save Bucharest - applied for the suspension of the ADC pending a court case to nullify the permit.
More than 100 offensive messages have been collected by ADC as part of their evidence for the increase in hateful messages and threats.
The ADC, which claims to be the biggest Arab civil rights group in the US, said it is working with the Federal Bureau of Investigation and police to assess the threats, which escalated early last week, just before the film went into general release.
