We'll rate this "Not Applicable" given the very early nature of the study and the fact that guadecitabine is clearly still far from approval for treating colorectal cancer so it would be difficult to put a precise dollar figure on it. It's worth noting, however, that guadecitabine is also being considered for use in treating acute myeloid leukemia (AML) and is much further along in development for that clinical application. In fact, there is already discussion about whether the potential benefits associated with using guadecitabine to treat AML outweigh the fact that other drugs are available in generic form (and are therefore less expensive). In short, while we don't expect a release to place a dollar amount on the use of guadecitabine, we always like to see the issue of cost addressed in some way. The release does a good job here in two ways. First, the release makes clear that the goal of this study was not to assess benefits, but to assess potential harms. That places the findings and the study design in context. Second, the release notes that 15 of the 22 patients had at least one imaging scan to track the extent and location of their cancers. Twelve of those 15 patients had "stable" disease, while one saw a 30 percent decrease in the size of the tumors. The headline is problematic, but we'll talk about that under the "Unjustifiable Language" criterion. The rest of the release does a good job of describing potential harms. The release discusses eight potential harms, defines them and offers numbers on all of them (e.g., "two patients developed thrombocytopenia, a lowered count of blood-clotting platelets"). That's very good. Two things would have made it even better. First, the release could have included an explanation of what the observed adverse effects actually mean. For example, how severe was the thrombocytopenia? And how much of a risk does that pose to a patient's health are we talking about the potential for bruising easily? Or a high risk of bleeding to death? Second, it wasn't clear if the dose of guadecitabine was related to observed effects. I.e., were patients who received higher doses of guadecitabine more likely to exhibit adverse effects? The release does a nice job here. The release sets the tone in its first sentence, which begins with: "In a small, phase I clinical trial". The release clearly explains the goals of the clinical trial, the number and type of patients involved, and the study design. The only thing that could have made things more clear would be if the release had told readers the size of the doses each of the four study groups received and whether dose size was related to observed effects. No disease mongering here. The release clearly states that the study was supported by Astex Pharmaceuticals, which manufactures guadecitabine. There are a lot of drugs, and drug combinations, that are approved for use in colorectal cancer chemotherapy. Given that the release explicitly states that the study was not done to assess the potential benefits of guadecitabine, we don't expect it to compare the drug's performance to those other drugs. The release makes clear that this was a preliminary trial and that a phase II trial is ongoing. That's good. In addition, the release states: "Guadecitabine is an experimental drug that has not been approved for use by the U.S. Food and Drug Administration." That's great. We wish all releases were this straight-forward about drug/treatment availability. As noted above, there are a lot of drugs and combinationsapproved for usein colorectal cancer chemotherapy. The release does a good job of explaining howguadecitabine may act against colorectal cancer. There are currently two FDA approved drugs that are classified asDNA methyltransferase inhibitors; decitabine (Dacogen) and azacitidine (Vidaza). Both had been used in clinical trials in the treatment of colon cancer. The bulk of the release is very good in this regard, but the first thing readers see is the headline. That doesn't mean the headline is more important, but it does mean that the headline is subject to additional scrutiny. And the headline here reaches too far. Here's the headline: "Experimental drug guadecitabine found safe in patients with colorectal cancer." Here's an excerpt from lower down in the release: "16 patients experienced neutropenia, a low count of the infection-fighting white blood cells called neutrophils; five patients with neutropenia had fevers; three patients became anemic; and two patients developed thrombocytopenia, a lowered count of blood-clotting platelets. Other side effects included diarrhea (three patients), fatigue (two patients) and dehydration (two patients). There was one death during the study, possibly resulting from febrile neutropenia caused by the treatment." The word "safe" is relative when discussing chemotherapy treatment, but when most readers see something described as "safe" they assume that means it won't harm them. For that reason, it's a stretch to apply the word "safe" to any treatment in which a sample size of 22 patients is associated with this many adverse outcomes, and may have contributed to a death.
