Richard Purkiss—Piper Jaffray—Analyst

Okay, just briefly — I notice we’re running short on time, but perhaps you can just share some thoughts on Allergan’s pipeline, what you find particularly interesting.

 

 

Mikael Dolsten—Pfizer Inc.—President, Worldwide Research & Development

Yes, I think the industry as a whole has many companies that are investing in R&D and providing product pipelines. So we think that some consolidation will make the industry more efficient. We certainly have seen Pfizer starting to have growth based on the PIXEL brands that you’ve alluded to.

Allergan is a Company that have accumulated a very robust, durable, marketed and pipeline product portfolio. So we see a combination of these companies to have an opportunity to aspire for growth across many therapeutic areas. I can see in some therapeutic areas where combining the two will give a very impressive portfolio.

Let me mention one area where we have been a significant investor in research and development that’s newer science. And Allergan obviously have a long history with Namenda Namzaric franchise and some more pipeline oriented products, like I mentioned, include, and this is from their R&D day —

 

 

Richard Purkiss—Piper Jaffray—Analyst

No, sure. Yes, no, no.

 DECEMBER 02, 2015 / 2:00PM, PFE—Pfizer Inc at Piper Jaffray Healthcare Conference

Mikael Dolsten—Pfizer Inc.—President, Worldwide Research & Development

— they spoke about and obviously more detailed question should come to the Allergan colleagues. Vraylar, which is a typical antipsychotic drug approved for schizophrenia and the mania bipolar disease. What’s interesting is that it shares some features with Abilify in that it’s a D2 partial agonist.

But it also has picked up D3 and that may be the reason why Allergan communicated interesting data on negative symptoms which could be a unique opportunity for this drug. And it behaved very well also on tolerability aspects such as metabolic function, so that’s, I think, an interesting drug.

 

 

Richard Purkiss—Piper Jaffray—Analyst

For psychiatrists as well. I mean negative — so that’s the big unmet need, really, isn’t it, negative symptoms?

 

 

Mikael Dolsten—Pfizer Inc.—President, Worldwide Research & Development

It is a huge unmet need and it makes — why many of these patients are unable to engage socially in society and are really hampered after controlling the positive symptoms. Another area, treatment resistant depression, I think is tremendous unmet need and the drug rapastinel which acts on the NMDA receptor pathway is for — initially for IV administration. It belongs to a class that had rapid onset of therapeutic benefit.

And so far what Allergan disclosed is that the drug has rapid beneficial effects seen in a small Phase 2 study while not having what has been associated with other candidates in this space, psychotropic or hallucinogenic effect. So that could be also a very transformative opportunity for refractory depression.

We have a significant effort to grow our presence in gastrointestinal disease. Allergan has a strong history in inflammatory bowel disease with an asset called Delzicol and more recently in irritable bowel symptoms both for the chronic constipation and diarrhea forms.

They really shared at R&D day also relamorelin which is a ghrelin cyclic peptidomimetic for diabetic gastroparesis, a condition many diabetes patients suffer from, inability optimally empty the gastric organ and thereby getting a lot of issue with nausea, vomiting and overall poor life quality. So that’s another very intriguing opportunity.

And finally, of course, they have the new businesses in the sense of ophthalmology and aesthetics that would be a very nice expansion into what our businesses. And I’m quite impressed with what they’ve done with both its lifecycle management and I think there is another opportunity in aesthetics with Kybella and in ophthalmology, I think we have tanezumab which works on the NGF pathway.

They actually have an NGF active drug that is licensed from Mimetogen, MIM-D3, that acts locally in the eye for dry eye to induce mucin production and reduce the symptoms.

So I just gave a couple of examples that I think are innovative drugs that could really advance care in many of these areas, would complement what Pfizer has. And I think that potential combination of these two companies could be very powerful. It will have a pipeline of more than 100 Phase 2 registration drugs of which more than 60 are in Phase 3 registration. So really an unprecedented powerhouse of R&D.

 

 

Richard Purkiss—Piper Jaffray—Analyst

I think we’re out of time. Anyway, thank you very much, Mikael.
