Roskamp Institute scientists in Sarasota have a promising drug in trials in Europe. It switches the Alzheimer factory off.<\/strong>

It starts as a protein, an organic compound of amino acids that is amorphous. Nebulous. Shaped like nothing, floating in the brain, passing through the blood barrier in small amounts. And like a pinch of vodka in soda water, they go unnoticed.<\/p>\n

But over time and for whatever reason \u2014 scientists aren\u2019t sure why \u2014more and more of these proteins start accumulating in the brain, blanketing synapses in a sticky kind of plaque and like fine, fine hairs gathering in the bristles of a brush, the brain starts to clog with these things called beta-amyloids.<\/p>\n

Under a microscope, the fibrous amyloids are no longer shapeless, nebulous things. They look like hairpins, twisty and stackable like Legos.<\/p>\n

If this were a game of Tetris, you would work feverishly to clear the screen. This is an oversimplified metaphor for Alzheimer\u2019s. But the description is not unlike what the scientists in white lab coats are doing on Whitfield Avenue in Sarasota.<\/p>\n

Not if \u2026 when\u00a0<\/strong>
\nDr. Michael Mullan is getting close to a cure. Real close.<\/p>\n

About a year and a half ago, Mullan, executive director of the Roskamp Institute \u2014 named after Sarasotans Bob and Diane Roskamp \u2014\u00a0 began administering a drug called Nilvadipine to Alzheimer\u2019s patients in Ireland.<\/p>\n

Nilvadipine, already approved in Europe for the treatment of hypertension, has been shown to stop the production of amyloid proteins.<\/p>\n

Remember the quickly filling Tetris screen? The falling shapes that gain speed as the game goes on? Nilvadipine stops the shapes from ever dropping.<\/p>\n

\u201c(It) stops the production of amyloid,\u201d says Mullan. \u201cStops the body from making it. Switches the factory off.\u201d<\/p>\n

It\u2019s only in phase one of European clinical trials, but Mullan predicts the drug will be introduced to clinical trial participants in Miami as early as this summer and throughout the rest of the United States next year.<\/p>\n

If and when it hits the market, Nilvadipine will be the Roskamp Institute\u2019s first marketable Alzheimer\u2019s drug under the institute\u2019s for-profit company, Archer Pharmaceuticals. It is one of several Alzheimer\u2019s drugs in the Roskamp pipeline.<\/p>\n

In the early 1990s, Mullan, along with Roskamp\u2019s associate director, Dr. Fiona Crawford, led a team of researchers in discovering the buildup of amyloid proteins that caused Alzheimer\u2019s disease.<\/p>\n

\u201cPeople used to talk about amyloid as being a tombstone, something that just showed up as a result of the disease,\u201d says Mullan. \u201cNo one had actually proved that it caused the disease. It used to be like looking at a plane wreck. You\u2019d have bits of airplane everywhere and you wouldn\u2019t know which part of the wreck was a result of the wreck and which part caused it.\u201d<\/p>\n

It was a major medical breakthrough. At the time Mullan and Crawford were working out of London University, until Roskamp and his wife endowed the University of South Florida with enough funds to continue the scientists research in Sarasota. Twelve years later the USF department expanded, and in 2003 the Roskamp Institute moved into Bausch & Lomb\u2019s former laboratories on Whitfield Avenue near the Sarasota-Bradenton International Airport.<\/p>\n

\u201cThe increasing awareness of Alzheimer\u2019s is primarily due to us living longer,\u201d says Mullan. \u201cRight now, the goal for all the clinical trials is to try to slow the disease, take the people who already have it and give them a drug. In the future, it would be great if we knew who was going to get it before they experienced memory loss, but we don\u2019t have a way of assessing that yet.\u201d<\/p>\n

Search for trial participants<\/strong>
\nJulia Parrish, LPN, the institute\u2019s clinical trials project manager, is recruiting volunteers for two clinical trials in Sarasota for two Alzheimer\u2019s drugs \u2014 an IV-administered medication called Bapineuzumab and an oral one called ELND005.<\/p>\n

Both trials are sponsored by Elan Pharmaceuticals, a neuroscience-based biotechnology company headquartered in Dublin, Ireland.<\/p>\n

The two drugs have been shown to attack the production of amyloid in different ways. Bapineuzumab works like a passive vaccine, seeping into the bloodstream soaking up amyloids like a sponge in the brain before they start to clump. ELND005 is an oral medication that has been shown to stop amyloids before they change shape and start stacking in the most advanced stages of Alzheimer\u2019s.<\/p>\n

Bapineuzumab is in phase three, the final phase of a clinical test before it goes before the U.S. Food and Drug Administration. ELND005 is in phase two. It\u2019s still unknown whether either drug reverses or halts the disease altogether.<\/p>\n

Parrish already has 50 participants in Sarasota, but she\u2019s looking for about 15 more. Candidates must be between the ages of 50 and 88 years old and diagnosed with mild to moderate Alzheimer\u2019s disease, however the clinic offers free cognitive screenings for people who have Alzheimer\u2019s symptoms but haven\u2019t been formally diagnosed yet.<\/p>\n

Hundreds of participants have already been dosed with Bapineuzumab and ELND005 in clinical trials across the country. Parrish said she isn\u2019t privy to those results. Project coordinators typically do not communicate.<\/p>\n

The two drugs are among seven amyloid-attacking Alzheimer\u2019s medications undergoing clinical testing in the United States, which according to Mullan and Parrish is a significant number when compared to five years ago.<\/p>\n

\u201cFrankly my view is that there aren\u2019t enough Alzheimer\u2019s drugs in clinical trials,\u201d says Mullan. \u201cIf we were talking about cancer, we\u2019d be talking about hundreds of new drugs every year.\u201d<\/p>\n

He has big hopes for Nilvadipine.<\/p>\n

He hopes the drug will get FDA approval in the next four years, at which point the Roskamp Institute can begin testing it on large groups of healthy participants before they experience memory loss.<\/p>\n

\u201cIn my mind, it isn\u2019t not a question of if we can cure Alzheimer\u2019s. It\u2019s a question of when,\u201d says Mullan. \u201cOnce we have drugs that are effective we can give them earlier, we can predict Alzheimer\u2019s before there\u2019s memory problems. It\u2019s an easy idea to say, but in practice I would say we\u2019re about five to 10 years away.\u201d<\/p>\n

PULL OUT BOX:<\/strong>
\nClinical volunteers needed!<\/p>\n

Roskamp is looking for participants for its clinical trials of Bapineuzumab and ELND005. If you\u2019re between the ages of 50 and 88 and have a diagnosis of probable Alzheimer\u2019s disease and have a caregiver who can drive you to and from the Roskamp Institute at 2040 Whitfield Avenue in Sarasota call Julia Parrish at 256-8018.<\/p>\n

The institute also offers free memory screenings<\/strong> for adults age 60 or older.<\/p>\n
