I am not the parent, but I worked at a few biotech startups.
My impression is that you are _mostly_ correct (a lot of animal models for disease don't accurately reflect the analogous state in humans).
However, I was privy to a situation similar to that described by the person to whom you replied.
* A start-up that I worked at developed a "candidate drug" to treat a condition (I don't want to get too detailed).
* The drug was good at ameliorating the disease in our simple models, but we also had a strong suspicion that the drug would be toxic in humans, higher animals.
* A decision was made that we would determine if the drug was toxic in three different species of large animal (I think we chose some type of monkey, dogs and I don't remember).
* Our "go/no-go" decision was: If the drug was NON-toxic in at least 2 of the 3 animal species, we would move to clinical (human) trials.
* 6 months later, we got the results: drug was NON-toxic in 1 of the 3 species.
* This looks like "no-go", right?
* Wrong. Board of directors put pressure on the CEO and senior management ("We put 8 figures of our hard-earned $ into round B and you promised us clinical trials over a year ago.").
* CEO folded like an accordion and got everyone to agree that we should proceed w/ Phase I trials (small n of humans tested, primarily to determine toxicity and maximum tolerated dose) despite the results of the animal studies.
* Phase 1 trial starts. Everyone gets sick (maybe 10 patients) after about 5 days of taking the drug. Trial is halted.
* We go back to square 1.
CEO should have never folded under the pressure because it was a waste of money, time, and it put people at risk.
I've only seen this once (going to trial with a risky drug), so I think it is a rare event.
edit2: Ironically, this is an example of a situation where the animal-studies CORRECTLY predicted what would happen in humans.

- busyant 8y agoAgreed. That company was unusual in that there always seemed to be a tension between the board and the company (distrust). And both sides (CEO and board) seemed to have a short-term view of everything (we were going to "flip" the company to a large pharma), which caused a lot of bad decisions to be made. The other (more successful) start-ups that I worked at had a much more harmonious relationship with their boards (e.g., "We are in this together and we are here for the long-term.")

Unfortunately, if they were trying to flip the company; then they may have made the 'right' (from the perspective of payoff) call. I can imagine under some models, that if you are 86% confident that it won't work, and only 14% confident that it will work; then the millions wasted may have been easily justified by the potential payoff if it was in the $100 million dollar range. Normally, we wouldn't bat an eye at such a decision; but the ugly part here is the high risk exposed to the people participating in the study :(. However, even that, a similar utilitarian calculus can be done to justify it. bleh. Remind me not to be a Pharma CEO, it sounds like an all around unpleasant job if you aren't a complete sociopath.
- DanBC 8y agoImagine a similar situation but where people died: Who's corporately responsible for that decision? The company, or the individual directors? How about the NEDs?
- busyant 8y ago> Imagine a similar situation but where people died: Who's corporately responsible for that decision? No idea. Thankfully, all patients stopped the drug and the toxicity went away. I remember having a company-wide meeting where they showed us a result from the Phase I trial. It was a graph of time on the x-axis and the concentration of an important molecule in each patient's bloodstream on the y-axis. Every patient had the concentration of that molecule drop to dangerously low levels after about 5 days on the drug, and I'm thinking, "Is this a surprise to anyone here?"
