Ja det kalder man nu et veloverstået fase 1!!!! forsøg. Tænk sig at den eufori langsomt og smertefuld skal fise ud af ballonen. Jeg har ingen illusioner længere. !

Men flot gået af forskerne bag. Håber virkeligt ikke at private aktionærer nogensinde skal blandes ind i det.

Det er da vist det vi andre kalder proof of concept. Måske de mener at de kan gå direkte i smittede efter dette. Det vil de så kalde fase 2b.

Men OK, Santaris har haft det hårdt, så de kan bruge lidt succes.

Det er faktisk et større gennembrud end som så. For det er verdens første micro RNA stof i udvikling. Så det kan være med til at åbne helt nye døre for Santaris Pharma at de nu kan opnå gode data. Men ja de har stadig langt vej endnu. Men spændende er det.....

SPC3649 successfully inhibits miR-122, a microRNA important for Hepatitis C viral replication, thereby significantly reducing Hepatitis C virus in the bloodstream in chimpanzees chronically infected with the Hepatitis C virus

SPC3649 demonstrates efficacy with no evidence of viral resistance and no serious adverse events in the treated animals ? signaling a potential benefit for patients who are not responsive to or cannot tolerate current standard of care therapies

SPC3649 is the first microRNA-targeted drug to enter human clinical trials; Phase 1 clinical trials ongoing

Santaris Pharma A/S proprietary Locked Nucleic Acid (LNA) Drug Platform fundamental in developing effective RNA-targeted therapies with high affinity, target specificity and remarkable potency for a range of diseases

Hoersholm, Denmark/San Diego, California, December 3, 2009 ? A study published online in this week?s Science shows that SPC3649, a breakthrough microRNA-targeted therapy developed by Santaris Pharma A/S using its proprietary Locked Nucleic Acid (LNA) technology, holds promise as a novel treatment for patients infected with the Hepatitis C virus (HCV).

The World Health Organization estimates about 3% of the world?s population has been infected with HCV and that some 170 million are chronic carriers at risk of developing liver cirrhosis and/or liver cancer[1]. Approximately 3-4 million Americans are chronically infected with an estimated 40,000 new infections per year[2]. In Europe, there are about 4 million carriers[3].

Santaris Pharma A/S, the first company to have advanced both mRNA and microRNA targeted drugs into clinical trials, is an international biopharmaceutical company focused on the discovery and development of RNA-targeted therapies for a range of diseases including metabolic disorders, infectious and inflammatory diseases, cancer and rare genetic disorders.

In this preclinical study, SPC3649 successfully inhibited miR-122, a liver-expressed microRNA important for Hepatitis C viral replication. By inhibiting miR-122, SPC3649 dramatically reduced Hepatitis C virus in the liver and in the bloodstream in chimpanzees chronically infected with the Hepatitis C virus[4]. Four HCV chronically infected chimpanzees were treated weekly with 5 or 1 mg/kg of SPC3649 for 12 weeks followed by a treatment free period of 17 weeks. The two animals that received the 5 mg/kg dose had a significant decline in viral levels in the blood and liver of approximately 2.5 orders of magnitude or approximately 350 fold[5].

?In collaborating with Santaris Pharma, we proved that the drug worked exceptionally well in treating HCV infections in chimpanzees,? said Robert Lanford, Ph.D., a scientist at the Southwest Foundation for Biomedical Research and one of the lead authors on the study. ?The current standard anti-HCV treatment, which combines pegylated interferon-alpha with ribavirin, is effective in only about 50% of patients and is often associated with severe side effects. Because of the unique mechanism of action of SPC3649 and its tolerability profile, this new therapy could have the potential to replace interferon to treat disease progression or be combined with current treatments.?

SPC3649 provided continued efficacy in the animals up to several months after the treatment period with no adverse events and no evidence of viral rebound or resistance, an important factor that distinguishes SPC3649 from direct antiviral HCV therapeutics.

Current antiviral therapies that target the virus directly are challenged as the HCV continually mutates to develop resistance to treatment. Because SPC3649 inhibits miR-122, an important microRNA involved in HCV replication, the HCV is blocked from replicating without the apparent selection of resistant mutants. SPC3649 has other important properties that make it attractive as a therapeutic agent for HCV. The preclinical data show changes in the expression of key genes that may help patients who do not respond to interferon treatment to become responsive.

SPC3649 is the first microRNA-targeted drug to enter human clinical trials and is currently undergoing Phase 1 clinical studies in healthy volunteers. These preclinical data provide even greater impetus to further examine the potential of SPC3649 for treating patients infected with HCV.

?Advancing the first microRNA-targeted therapy, SPC3649, into human clinical trials was certainly a breakthrough in science and we are very encouraged by these preclinical findings demonstrating that SPC3649 has the potential to be an effective treatment for patients infected with the Hepatitis C virus,? said Henrik Ørum, PhD, Vice President and Chief Scientific Officer of Santaris Pharma A/S. ?In drug discovery and development programs internally and with our partners, we continue to demonstrate that our proprietary LNA Drug Platform is fundamental in developing effective RNA-targeted therapies with high affinity, target specificity and remarkable potency for a range of diseases.?

Santaris Pharma A/S has a robust product pipeline based on its proprietary LNA technology including mRNA and microRNA drug discovery and development partnerships and collaborations with Shire (rare genetic disorders), Wyeth, now part of Pfizer, (delivery of lead candidates against up to ten targets), GlaxoSmithKline (four viral disease drug candidates) and Enzon Pharmaceuticals (eight cancer targets successfully delivered).

About Locked Nucleic Acid (LNA) Drug Platform
The Locked Nucleic Acid (LNA) Drug Platform developed by Santaris Pharma A/S creates synthetically modified chemical versions of the normal nucleic acid building blocks of ribonucleic acids (RNA). These modified chemical versions called LNAs improve the drug-like qualities of resulting therapeutics (oligonucleotides) by improving affinity to their target RNA, boosting resistance to metabolism and improving tissue uptake. Upon systemic administration of these ?naked? molecules, LNA-based therapeutics are delivered to many different tissues where they show potencies many-fold better than other oligonucleotide therapeutics.

About Santaris Pharma A/S
Santaris Pharma A/S is a clinical-stage biopharmaceutical company focused on the discovery and development of RNA-targeted therapies. The Company?s proprietary Locked Nucleic Acid (LNA) drug platform, in combination with its highly specialized and targeted drug development capabilities, offers potential partners pre-screened drug candidates for commercial consideration across a multitude of disease states. The Company?s own research and development activities focus on infectious diseases and metabolic disorders while partnerships with major pharmaceutical companies include a range of therapeutic areas including cancer, rare genetic disorders and inflammatory diseases. Santaris Pharma A/S, founded in 2003, is privately-held and headquartered in Denmark with operations in the US. The Company has strategic partnerships with Enzon Pharmaceuticals, GlaxoSmithKline, Wyeth Pharmaceuticals (now part of Pfizer) and Shire plc. Please visit www.santaris.com for more information.

Ok, de kalder så heller ikkke deres PoC for phase 1 studie.

Nej der er trods alt kun tale om prækliniske data der nu er blevet publiceret. Så der er pænt langt endnu. Men Santaris har nu gjort det flot med den række af store aftaler de har landet. De har "bare" brug for et par år mere til at modnes. Så tror jeg vi vil se dem lave en IPO i 2012-13 forudsat markedet tillader det

Nyheden har også ramt reuters. Reuters som i øverigt i dag har fået en kæmpe makeover

Ærgeligt for Santaris at en del publikationer tyder på at SPC3649 vil give cancer. I al fald er microRNA-122 nu karakteriseret som en tumor suppressor og det er kendt at den nedregulerer talrige oncogener.

God fornøjelse med at rekruttere frivillige forsøgspersoner til det næste fase 1 studie.
