Preferential action on DA reuptake transporter? Wouldnt that create addiction potential?

DOV Initiates Phase I Trial With DOV 102,677 for Depression
2005-02-24 07:30 (New York)





HACKENSACK, N.J., Feb. 24 /PRNewswire-FirstCall/ -- DOV Pharmaceutical,
Inc. (Nasdaq: DOVP), a leader in triple reuptake inhibitor drug discovery and
development, announced today that it has initiated the first Phase I clinical
trial with DOV 102,677, believed to be a potent inhibitor of serotonin,
norepinephrine and dopamine reuptake, with preferential action on the dopamine
transporter protein. DOV 102,677 is the third of DOV's triple reuptake
inhibitors to enter the clinic. This clinical trial is a double-blind,
randomized, placebo controlled study to evaluate the safety, pharmacokinetics
and pharmacodynamics of a range of escalating single doses of DOV 102,677 in
healthy volunteers. The trial is being conducted under a U.S. investigational
new drug application (IND).

No currently marketed antidepressant inhibits the reuptake of all three
neurotransmitters linked to depression: serotonin, norepinephrine and
dopamine. Both preclinical studies and clinical trials indicate that a drug
inhibiting reuptake of all three such neurotransmitters will produce more
rapid onset of action and greater efficacy than traditional antidepressants.
DOV believes that such a "broad spectrum" antidepressant could represent a
breakthrough in the treatment of depression. Based upon preclinical studies,
DOV 102,677 has potential utility in the treatment of depression, attention
deficit disorder and obesity.

Dr. Phil Skolnick, DOV's Senior Vice President, Research and Chief
Scientific Officer, stated, "DOV 102,677 is the second compound from our
internal preclinical discovery program to enter the clinic, with DOV 21,947
the first. We are excited to advance this compound into the clinic because it
both underscores the robustness of our discovery programs and validates our
strategy of relying, in part, on our internal discovery effort to fuel our
pipeline. Following completion of this clinical trial, we intend, in 2005, to
initiate two additional Phase I clinical trials and a Phase II clinical trial
for DOV 102,677."

DOV's discovery efforts have yielded a growing library of novel triple
reuptake inhibitors and the Company intends to bring at least one of these
compounds into clinical development annually. DOV 102,677 is related to DOV
216,303 and DOV 21,947, the two clinical-stage triple reuptake inhibitors
licensed to a subsidiary of Merck & Co. Inc., or Merck, in September 2004. In
the Merck transaction, DOV received a $35 million up-front licensing payment
with the opportunity to receive an additional $300 million for achieving
clinical development, regulatory and approval milestones and $120 million upon
achievement of targeted sales thresholds. Merck has rights of first offer and
refusal if the Company determines to commercialize DOV 102,677 for depression
or anxiety. Before licensing DOV 21,947 to Merck, DOV obtained an IND and
completed four Phase I pharmacokinetic clinical trials, including a Phase Ib
clinical trial of multiple doses of DOV 21,947. For DOV 216,303, DOV
completed two Phase I pharmacokinetic clinical trials and a Phase II multi-
centered, double-blind, safety, efficacy and tolerability clinical trial that
compared DOV 216,303 to citalopram, a selective serotonin reuptake inhibitor,
or SSRI, in patients with major depressive disorder.

Dr. Arnold Lippa, DOV's CEO, will cover the above information at his
corporate presentation scheduled for 12:00 noon today at the BIO CEO
Conference 2005 at the Waldorf-Astoria in New York City.


About DOV

DOV is a biopharmaceutical company focused on the discovery, acquisition,
development and commercialization of novel drug candidates for central nervous
system and other disorders, including cardiovascular, that involve alterations
in neuronal processing. We have six product candidates undergoing clinical
development that address therapeutic indications with significant unmet needs.
In addition, our partner, Neurocrine, in the fourth quarter of 2004 filed two
NDAs, the first for an immediate release formulation and the second for a
modified release formulation of indiplon for the treatment of insomnia.
However, Neurocrine has announced that these applications were not accepted by
the FDA due to technical difficulties in navigating the electronic filing and
that it intends to refile the applications in the first half of 2005.

Another piece of evidence that not all dopamine reuptake inhibitors are suitable as recreational drugs.
 
What do you mean "not all". Find me a specific dopamine uptake inhibitor which IS fun.
 
Nowhere did I say specific. This is a good example that even non-specific uptake inhibitors aren't necessarily fun. The company wouldn't put anything into clinical trials for depression that has abuse/fun potential. A very similar compound, DOV 216,303 is safe and well-tolerated in Phase I studies. Thus, no euphoria or such thing.

But to answer your question: isn't amfonelic acid quite selective for DAT and thought to have abuse potential?
 
http://www.neurotransmitter.net/newdrugs.html

There's a list of "Future Treatments for Depression, Anxiety, Insomnia, and Psychosis." There are a few triple reuptake inhibitors on there. Anyone have any input (guesses) about the potential efficacy of this (or any) triple reuptake inhibitors? Common sense leads me to believe that these would be no more effective than combining Cymbalta (a dual reuptake inhibitor of SERT/NET) and Wellbutrin (dopamine reuptake inhibitor). Combining the recommended doses (60 mg/day Cymbalta and 300 mg/day Wellbutrin) of those 2 A/Ds theoretically should have the same efficacy as whatever the recommended dose of this new "triple reuptake inhibitor" is...or am I off base on this assumption?
 
I don't know, I've never hear of reports of amfonelic acid use in humans.

As far as I'm concerned triple uptake inhibitors are going to be fun, to a degree, so long as they have fast absorption/distibution pharmacokinetics...
 
If drug is effective at what is purposes to do, this will have great positive effects on society.

Depression, ADD, Anxiety and other common forms of mental illness are more prevelant in our society then numbers suggest. I have a feeling that only around a quarter of people with these problems are being diagnosed and treated.

I personally have severe ADD \ 3 forms of Anxiety \ Depression. I have to take a regime of drugs to just achieve normal status.

This medication may possibly take the following drugs out of my daily\semi-daily drug regime: Ritalin, Ativan, Zopiclone, Ephedrine, MSM. And it will replace Paxil.

Before this drug regime I was a non-functional mess. Productivity, happiness and other positive bennifits will come with this drug.

The abuse issue... I do not think we will see tradiational abuse of this drug. However I can see a potential abuse problem, if you can call it that. I personally would not hesistate to seek a higher and higher dose if the drug could boost functioning, until I could not boost it any more or until it could not work better.

But this will just increase productivity, eliminate depression and create more effective humans. At the cost of our natural, primitive genetic selves. Pregrogrammed selfish genetics are plauging humans who have evolved beyond the jungle.

I am hedonistic so I am greatly excited by this. The naturalists are probally going to have a fit.
 
It personally pisses me off that pharmacists avoid dopamine. There was something on biopsychiatry about a serotonin/dopamine reuptake inhibitor that was banned in the UK and never approved in the US. Bullshit.

Don't they get that noradrenaline just doesn't do the trick for offsetting the symptoms of SSRIs?
 
I doubt your problem, Spiritus, has much to do with selfish genes.

Because opioids are peptides, and hence not subjected to uptake carriers.
 
However, similar to MAO inhibitors blocking the breakdown of monoamines, enkephalinase inhibitors such as BL-2401 have been developed to block the breakdown of opioid peptides.
 
C6H6- like if I cut my dope with BL-2401 I can have an infinite rush? where can i steal this shit? (:
 
There was something posted about grapefruit juice potentiating opiates. I would never have believed it but there does appear to be a method to the madness.
 
Shit, peptides are amino acids joined at the carboxyl acid. DA and NE are catecholamines, and 5HT is a indolamine? So Bilz0r, theres no reuptake mechanism for opiods? What is the method of removal from the synapse? Is there a pharmacological way to manipulate the mechanism of synapse cleaning?

Smyth, I think grapefruit juice potentiates opiates because it affects the CYP3A4 enzyme system, which is involved in opiate destruction.
 
D_DOOD: No, it would only slightly change an opioid-induced high. Enkephalinease inhibitors only stop the break down of natural (aka endogenous) opioids, not opiates.

As people have said, it's removed via enzymatic degredation... it's something that has probably been investigated plenty behind closed doors, but there isn't that much published in the public sphere. It's quite possible that there are other things going on, but for a diffuse neuromodulatory sysmte, rapid clerance isn't really an issue.
 
Most likely not, D_DOOD, sorry to dissapoint you. No need to sneak up on a certain Japanese pharmaceutical company with a crowbar in your napsack.

But I have something for you: patent WO 2004096144 discloses "Compositions and Methods for Induction of Opioid Receptors". The idea is to potentiate the high by growing more receptors for the good dope. Double amount of receptors = double rush!

Nope I think you missed my point there. Selfish genes that program now unnessasary functions such as shyness is what I meant.

I do not know the awnser to this, but I do know that grapefruit juice (a chem in it actually) and some drugs are metabolized by the CYPD26 emzyme and it's usefull for increasing the effects of DXM and any other drug that uses that route.

Now one thing I do know that potentiates opiates is DXM. It can remove tolerance and potentiate it. However if you are going to play with this one use much caution or you are dead.
 
I don't think genes probably program Shyness... I think parents probably do.

Meanwhile, It's CYP3As that grapefruit inhibits, not cyp2d6.
 
:) I agree. And thanks for the correction, I was reading about this the other day and confused the two.
