Cancer drugs are crowding in to an already cramped pipeline this year, with hundreds of immuno-oncology hopefuls now taking a shot at clinical testing. That�s according to a new cancer report from PhRMA, which counted 1,120 oncology drugs in the clinic so far this year � a massive increase from previous years � and that�s just in the US.
For perspective, there were only 836 cancer therapies counted by PhRMA in 2015, which means the pipeline has swelled 34% in less than three years. The organization only counted drugs already in the clinic or awaiting review from the FDA. That means there�s a significant backlog of therapies in preclinical development, waiting to elbow their way into the fray.
Of the 1,120 therapies in the clinic, nearly 300 are immuno-oncology drugs or vaccines. And just what counts as immuno-oncology? The organization said it counted �recognized classes� such as CAR-T therapies, bi-specific antibodies, cytokine therapies, immune checkpoint modulators, oncolytic virus therapies, and vaccines.

The report takes a regional look at a trend we�ve been tracking for a while now. Back in January, an Endpoints News�panel discussed the rapid expansion of the oncology pipeline (in particular, immuno-oncology) at the JP Morgan Healthcare Conference in San Francisco. That report identified a mind-boggling 2,004 immuno-oncology agents, with 940 in the clinic and the rest in preclinical development.
There�s been an ongoing discussion about whether the market can support the crowding in fields such as PD-1/L1 � not just in the US, but in China and other regions.
For its part, PhRMA remains upbeat about the pipeline, touting the industry�s innovations and calling attention to the 85% of cancer drugs in development it says are first-in-class treatments. And the organization is quick to point out that the need for new cancer treatments is still crucial. Although cancer death rate has declined 26% since its peak in the 1990s, more than 1.7 million new cases of cancer are expected to develop in the US in 2018.
