GenVec may end deal with British firm
Washington Business Journal - by Vandana Sinha Staff Reporter
GenVec Inc. is considering whether to end a two-year manufacturing agreement it had signed with a United Kingdom company six months earlier than planned.
The Gaithersburg biotech said it’s suspending the manufacturing activities of its key anticancer product, TNFerade, with Cobra Biomanufacturing PLC, in part to help cap its expenses and make it a more attractive prospect for potential partners.
The companies first entered into their agreement in January 2008 for Cobra to help GenVec scale up its production capacity of TNFerade at its plant in Oxford, England. At the time, GenVec paid a $1 million advance fee to Cobra for a two-year contract whose value could rise as much as $9.4 million depending on the services provided. Last year, GenVec said it paid Cobra $3.4 million.
But GenVec has been in discussions with other larger players to partner with the smaller company and help it fund its clinical trials and anticipated launch of TNFerade, which is in its third and most expensive phase of human tests as a pancreatic cancer treatment.
“We don’t need this [manufacturing agreement with Cobra] to continue the clinical trial,” said Doug Swirsky, senior vice president, chief financial officer, treasurer and corporate secretary for GenVec (NASDAQ: GNVC), declining to comment on whether a partnership deal is imminent. “If we partner with someone who has that manufacturing capability, we would want to transfer the process to them and work with them, so this provides us flexibility.”
GenVec said it will pay Cobra $1.8 million for any manufacturing services through June of this year, when it will decide whether or not to end the contract. If it does put an end to it, GenVec will pay Cobra a final termination fee of $350,000, a significant decrease that the local company negotiated from the one-time maximum fee amount of $2.3 million.
But the company said this also helps it slash costs during a harsh economic environment. In January, the company said it cut discretionary spending, as well as 22 positions, bringing its head count down to 98 full-time people and extending its cash lifeline from 18 months to two years.
“We’re trying to be as efficient as possible,” Swirsky said. “We did see an attractive way to limit our continuing contractual obligations.”

ist ja komisch....Hammernews und keinen interessierts
GenVec Inc. in Gaithersburg and drug giant Novartis AG have formed a development partnership to advance treatments for hearing loss and balance disorders.
GenVec said that it would receive $5 million upfront from Novartis as well as additional development funding. GenVec would also be eligible to receive royalties on futures sales and could earn up to $213 million in milestone payment if certain goals are met.
Under terms of the agreement, GenVec is licensing the world-wide rights to its preclinical hearing loss and balance disorders program to Novartis. GenVec said that results from the effort suggest that delivery of the atonal gene using GenVec's innovative adenovector technology may have the potential to restore hearing and balance function.
As part of the partnership, Novartis purchased $2 million in GenVec common stock. The shares (NASDAQ: GNVC), which were threatened with delisting less than a month ago, rallied as much as 42 cents, or 24 percent, to $2.16 in Tuesday trading. The shares have quadrupled in the last 12 months.
GenVec is not the only Washington-area biotech that has piqued Novartis’ interest. In October 2009, Vanda Pharmaceuticals signed a development and sales agreement with Novartis for a schizophrenia drug that could yield as much as $465 million for the Rockville-based biotech.

Die Aktie hat im Jahre 2010 noch bei rund 33 US$ notiert und seit dem 95% an Wert verloren und nach dem dead cat bounce der letzten Jahre nunmehr zuletzt bei 1.34 US$ ihr Allzeittief markiert.
Bereits im letzten Jahr sind die Insider eingestiegen - und begannen bereits bei 2.87 US$ je Aktie zu kaufen.
Die aktuelle marcet cap liegt auf Niveau der Barmittel des Unternehmens.
Somit wird weder dem 206 Millionen US$ Deal mit Novartis Rechnung getragen, noch den anderen Medikamenten bzw. Therapeutica in der Produktpipeline.
Die FMD-Vakzine wurde in der Zwischenzeit erfolgreich durch das Zulassungsverfahren der FDA gebracht und auslizensiert. Hier dürften zukünftig erste Royalities fliessen.
Die aktuelle Marcet Cap ist so niedrig, dass man auch von einer krassen Unterbewertung sprechen kann.
Ähnliche Biotechwerte werden normalerweise mit 100-250 Millionen US-Dollar am Markt bewertet - teilweise auch bis zu 500 Millionen US-Dollar.
Zum Vergleich - die marcet cap liegt derzeit bei lediglich knapp 21 Millionen US-Dollar.
Die Aktie ist somit ein potentieller Tenbagger bzw. ein potentielles Übernahmeziel.
Mit Atoh1- Genetransfer mittels Adenoviren besteht die Chance zusammen mit Novartis einen potentiellen Blockbuster zu entwickeln und auf den Weg zu bringen - und zwar auf eine wahre Revolution in Sachen Wiederherstellung des Cortiorgans des Innenohrs und von verloren geglaubten Haarzellen des Innenohrs und Gleichgewichtsorgans.
Hier drin steckt für wahr ein wahrhaft revolutionärer Therapieansatz, der die gesamte Welt der HNO-Ärzte weltweit verändern kann und der Alptraum der Gehörgeräteakustiker sein dürfte.
Ein Leben ohne Hörgerät - durch Regeneration verlorengelaubter Sinneszellen im Innenohr? Klingt wie Science Fiction, ist aber in Tierversuchen bereits wiederholt erfolgreich angewendet worden. Ich gehe davon aus, dass diese Form der Therapie auch beim Menschen funktioniert. Wenn dem so ist werden damit jedes Jahr Milliarden verdient.

Vestibular regeneration - experimental models and clinical implications.

Second Department of Otolaryngology, University of Medicine and Pharmacy Cluj-Napoca, Cluj-Napoca, Romania.
Abstract
Therapies aimed at the protection and/or regeneration of inner ear hair cells are of great interest, given the significant monetary and quality of life impact of balance disorders. Different viral vectors have been shown to transfect various cell types in the inner ear. The past decade has provided tremendous advances in the use of adenoviral vectors to achieve targeted treatment delivery. Several routes of delivery have been identified to introduce vectors into the inner ear while minimizing injury to surrounding structures. Recently, the transcription factor Atoh1 was determined to play a critical role in hair cell differentiation. Adenoviral-mediated overexpression of Atoh1 in culture and in vivo has demonstrated the ability to regenerate vestibular hair cells by causing transdifferentiation of neighbouring epithelial-supporting cells. Functional recovery of the vestibular system has also been documented following adenoviral-induced Atoh1 overexpression. Experiments demonstrating gene transfer in human vestibular epithelial cells reveal that the human inner ear is a suitable target for gene therapy.

Das ist begrüssenswert, da damit Aktionärsfreundlich Mittel für sinnvolle Massnahmen ausgegeben werden.
Genvec ist bei der aktuellen Marcet Cap weiterhin unterebewertet - die gesamte Produktpipeline gibt es derzeit quasi für lau.
Dabei ist allein der Deal mit Novartis 206 Millionen US$ wert - also das zehnfache der aktuellen Market Cap.
Ich gehe davon aus, dass hier demnächst neue Meilensteinzahlungen kommen werden, sofern Genvec nicht kurzerhand aufgekauft wird.

Repair of the vestibular system via adenovector delivery of Atoh1: a potential treatment for balance disorders.

University of Maryland School of Medicine, Baltimore, MD, USA.
Abstract
Loss of auditory and vestibular hair cells is a common cause of hearing loss and balance disorders. A variety of strategies have been proposed to restore function to damaged inner ear neuroepithelium. Delivery of the atonal homolog, atoh1, has been demonstrated to induce recovery of auditory and vestibular hair cells using a variety of delivery methods and model systems. We have developed a mouse model of vestibular aminoglycoside ototoxicity and demonstrated that delivery of an advanced generation adenovector that expresses atoh1 results in the regeneration of vestibular hair cells. Additionally, mice treated with atoh1 recover balance function. Currently vestibular diseases have few treatment options and several lines of evidence suggest that regeneration of hair cells may be more easily accomplished in the vestibular system. Development of atoh1-based gene therapy for vestibular hair cell loss may provide an initial opportunity for developing gene therapy for inner ear disease.

We have developed a mouse model of vestibular aminoglycoside ototoxicity and demonstrated that delivery of an advanced generation adenovector that expresses atoh1 results in the regeneration of vestibular hair cells. Additionally, mice treated with atoh1 recover balance function. Currently vestibular diseases have few treatment options and several lines of evidence suggest that regeneration of hair cells may be more easily accomplished in the vestibular system. Development of atoh1-based gene therapy for vestibular hair cell loss may provide an initial opportunity for developing gene therapy for inner ear disease.
Innerhalb der kommenden 2 1/2 Jahre rechne ich mit einer Verzwangifachung des Kurses bei Genvec, sofern Novartis, die dieser Tage wieder ein Pharmaunternehmen aufgekauft haben, Genvec nicht vorher aufkaufen.
Bis zum Jahr 2020 wird sich der Kurs dann wahrscheinlich verhundertfacht haben, wenn die Aktie dem Beispiel von Regeneraon folgt.

Das sind hervorragende Studienergebnisse die Genvec da heute veröffentlicht hat
Co announced that data were presented on GenVec's respiratory syncytial virus (RSV) vaccine program at the "8th Annual International Respiratory Syncytial Virus Symposium," which took place in Santa Fe, New Mexico from September 27-30, 2012. Data presented at the conference demonstrated GenVec's universal RSV vaccine candidate is highly immunogenic and produces durable and broad protection from a single intramuscular administration. Protection in cotton rat and mouse models was characterized by functional RSV neutralizing antibodies and no disease potentiation was observed. GenVec's RSV vaccine candidate utilizes a proprietary adenovirus that is capable of generating a broad immune response while avoiding the problems of vector specific immunity that has hampered other vectored vaccines.

Antwort auf Beitrag Nr.: 43.666.407 von Macrocosmonaut am 01.10.12 20:53:38Ein paar Zahlen zum Marktpotential eines RSV-Impfstoffes um zu verdeutlichen wie gross das Marktpotential in diesem Segment ist:
Palizumab machte in 2011 rund 900 Millionen US-Dollar Jahresumsatz, und wird in diesem Jahr von Motavizumab mit rund 1.3 Milliarden US$ Jahresumsatz übertroffen. Der Motavizumab wird bis 2015 auf rund 1.8 Milliarden jährlich ansteigen - allerdings ist davon auszugehen, dass mit Einführung eines Impfstoffes grosse Teile dieser Umsäte an den Impfstoffhersteller wandern werden.
Ich gehe daher davon aus, dass bis 2020 der RSV-Impfstoffmarkt Umsätze von jährlich bis zu 2 Milliarden US-Dollar erwirtschaften kann - gemessen auf der Grundlage der Ausgaben für die derzeitigen o.g. Therapeutika.
Jährlich werden in den Industrienationen mehr als 3.5 Millionen Menschen mit RSV-infiziert. Mehr als 175000 Erwachsene müssen zur Behandlung stationär aufgenommern werden, mehr als 125000 Kinder sind ebenfalls stationär behandlungspflichtig und mehr als 90000 Säuglinge ebenfalls.

Abstract
Background
The Step trial raised the possibility that uncircumcised men with pre-existing Ad5 neutralizing antibodies carried an increased risk of HIV infection after vaccination. Thus, understanding Ad seropositivity in humans is important to the development of an AIDS vaccine. Here, we analyze the impact of different Ad5-specific neutralizing antibodies on immune function and clinical outcome.
Methods and Findings
Ad seropositivity in the Step trial volunteers was analyzed using chimeric rAd5/35 vectors to characterize their specificity for Ad5 fiber and non-fiber external (capsid) proteins. Immune responses and HIV seropositivity were correlated with the specificity of Ad5-neutralizing antibodies. Neutralizing antibodies induced by the vaccine in Ad5 seronegative subjects were directed preferentially to Ad5 capsid proteins, although some fiber-neutralizing antibodies could be detected. Pre-vaccination Ad5 serostatus did not affect the capsid-directed response after three vaccinations. In contrast, anti-fiber antibody titers were significantly higher in volunteers who were Ad5 seropositive prior to vaccination. Those Ad5 seropositive subjects who generated anti-capsid responses showed a marked reduction in vaccine-induced CD8 responses. Unexpectedly, anti-vector immunity differed qualitatively in Ad5 seropositive participants who became HIV-1 infected compared to uninfected case controls; Ad5 seropositive participants who later acquired HIV had lower neutralizing antibodies to capsid. Moreover, Ad35 seropositivity was decreased in HIV-infected subjects compared with uninfected case controls, while seroprevalence for other serotypes including Ad14, Ad28 and Ad41 was similar in both groups.
Conclusions
Together, these findings suggest that the case subjects were less immunologically responsive prior to infection. Subjects infected during the Step trial had qualitative differences in immunity that increased their risk of HIV-1 infection independent of vaccination.

GenVec Enters Into $3.5 Million Contract With Naval Medical Research Center To Advance Malaria Program
2012-10-02 06:55 ET - News Release
GAITHERSBURG, Md., Oct. 2, 2012 /PRNewswire/ -- GenVec, Inc. (Nasdaq: GNVC) announced today that it has signed an agreement worth approximately $3.5 million with the Naval Medical Research Center (NMRC) to support malaria vaccine development.
Under the terms of the agreement, GenVec is responsible for producing clinical supplies of its malaria vaccine, which utilizes its novel, proprietary technology. NMRC plans to use this clinical material to assess the safety and efficacy of these next-generation vectored vaccines using the clinical challenge model developed by NMRC and the Walter Reed Army Institute of Research (WRAIR) malaria vaccine programs, which now are unified as the US Military Malaria Vaccine Program (USMMVP). GenVec retains the right to commercialize this novel technology. GenVec's malaria vaccine candidate utilizes a novel, proprietary adenovector delivery system that is capable of generating strong immune responses while avoiding the problems of vector-specific immunity that has hampered other vectored vaccines.
In April 2010, encouraging clinical data were presented from a Phase 1 malaria vaccine trial conducted by NMRC and WRAIR using GenVec adenovector technology coupled with DNA plasmid priming. Data indicate this DNA/adenovector malaria vaccine given to malaria-naive adults was safe and well-tolerated with minimal local or systemic reactions and no serious vaccine-related adverse reactions. Sterile protection, a complete absence of parasites in the blood, was seen in 4 out of 15 volunteers that had been inoculated with the vaccine and subsequently challenged with the malaria parasite.
"We appreciate the US military's continued commitment to the worldwide problem of malaria and its support of malaria vaccine development," said Dr. Joseph Bruder, Director of Research and head of GenVec's malaria program. "Work under this agreement will build upon the encouraging clinical results previously demonstrated in malaria with our vaccines."
About Malaria
Malaria is one of the world's most widespread and burdensome infectious diseases. This life-threatening parasitic infection is transmitted to humans through the bite of an infected mosquito. Malaria parasites initially invade liver cells and, after multiplying, release tens of thousands of new parasites, which invade red blood cells, multiply again, and then destroy these cells. High fever, headache, and shaking chills appear approximately nine to fourteen days after the infectious bite. If untreated, the infection can progress rapidly and become life threatening—destroying red blood cells, causing severe anemia, and blocking capillaries that nourish the brain and other vital organs, resulting in multisystem failure, coma and death. Malaria causes approximately 243 million acute illnesses and 863,000 deaths annually, mostly among children under the age of five. Malaria is a major health risk for travelers and the military.

Abstract
BACKGROUND:
We conducted a phase I, randomized, double-blind, placebo-controlled trial to assess the safety and immunogenicity of escalating doses of two recombinant replication defective adenovirus serotype 35 (Ad35) vectors containing gag, reverse transcriptase, integrase and nef (Ad35-GRIN) and env (Ad35-ENV), both derived from HIV-1 subtype A isolates. The trial enrolled 56 healthy HIV-uninfected adults.
METHODS:
Ad35-GRIN/ENV (Ad35-GRIN and Ad35-ENV mixed in the same vial in equal proportions) or Ad35-GRIN was administered intramuscularly at 0 and 6 months. Participants were randomized to receive either vaccine or placebo (10/4 per group, respectively) within one of four dosage groups: Ad35-GRIN/ENV 2×10(9) (A), 2×10(10) (B), 2×10(11) (C), or Ad35-GRIN 1×10(10) (D) viral particles.
RESULTS:
No vaccine-related serious adverse event was reported. Reactogenicity events reported were dose-dependent, mostly mild or moderate, some severe in Group C volunteers, all transient and resolving spontaneously. IFN-γ ELISPOT responses to any vaccine antigen were detected in 50, 56, 70 and 90% after the first vaccination, and in 75, 100, 88 and 86% of Groups A-D vaccine recipients after the second vaccination, respectively. The median spot forming cells (SFC) per 10(6) PBMC to any antigen was 78-139 across Groups A-C and 158-174 in Group D, after each of the vaccinations with a maximum of 2991 SFC. Four to five HIV proteins were commonly recognized across all the groups and over multiple timepoints. CD4+ and CD8+ T-cell responses were polyfunctional. Env antibodies were detected in all Group A-C vaccinees and Gag antibodies in most vaccinees after the second immunization. Ad35 neutralizing titers remained low after the second vaccination.
CONCLUSION/SIGNIFICANCE:
Ad35-GRIN/ENV reactogenicity was dose-related. HIV-specific cellular and humoral responses were seen in the majority of volunteers immunized with Ad35-GRIN/ENV or Ad35-GRIN and increased after the second vaccination. T-cell responses were broad and polyfunctional.
TRIAL REGISTRATION:
ClinicalTrials.gov NCT00851383.
Über Genvec´s Ad35 Entwicklungen wird man wahrscheinlich noch mehr hören - funktioniert nach einen Recherchen besser als die bis dato viel untersuchte ad5 Ansatz bei anderen Studien.

Abstract
BACKGROUND:
Neoadjuvant chemoradiotherapy followed by surgery is the primary treatment option for patients with locally advanced esophageal cancer. This multicenter phase I trial examined intratumoral injection of TNFerade biologic, an adenoviral vector that expresses the human tumor necrosis factor-α gene, with chemoradiotherapy in locally advanced esophageal cancer.
OBJECTIVES:
To assess pathologic complete response (pCR), time to disease progression, progression-free survival, survival, and safety and tolerance in patients treated with preoperative chemoradiation combined with endoscopy or EUS-guided intratumoral injection of TNFerade biologic.
DESIGN/INTERVENTION:
Five weekly injections of TNFerade biologic, dose-escalated logarithmically from 4 × 10(8) to 4 × 10(11) particle units (PU), were given in combination with cisplatin 75 mg/m(2) and intravenous 5-fluorouracil 1000 mg/m(2)/d for 96 hours on days 1 and 29, and concurrent radiation therapy to 45 Gy. Surgery was performed 9 to 15 weeks after treatment.
SETTING:
U.S. multicenter study.
PATIENTS:
Patients with stage II and III esophageal cancer were enrolled.
MAIN OUTCOME MEASUREMENTS:
Primary outcome measures were safety, feasibility, tolerability, and rate of pCR. Secondary outcome measures were overall survival (OS) and disease-free survival.
RESULTS:
Twenty-four patients with a median age of 61 years were enrolled; 88% of the patients were men, 21% were stage II, and 79% were stage III. Six (29%) had a pCR, observed among 21 patients (20 who underwent esophagectomy and 1 at autopsy). Dose-limiting toxicities were not observed. The most frequent potentially related adverse events were fatigue (54%), fever (38%), nausea (29%), vomiting (21%), esophagitis (21%), and chills (21%). At the top dose of 4 × 10(11) PU, thromboembolic events developed in 5 of 8 patients. The median OS was 47.8 months. The 3- and 5-year OS rates and disease-free survival rates were 54% and 41% and 38% and 38%, respectively.
LIMITATIONS:
We included primarily adenocarcinoma.
CONCLUSIONS:
Preoperative TNFerade, in combination with chemoradiotherapy, is active and safe at doses up to 4 × 10(10) PU and is associated with long survival. This regimen warrants additional studies.
Es scheint so als ob TNFerade beim Speiseröhrenkrebs einen lebensverlängernden Effekt hat.

To assess pathologic complete response (pCR), time to disease progression, progression-free survival, survival, and safety and tolerance in patients treated with preoperative chemoradiation combined with endoscopy or EUS-guided intratumoral injection of TNFerade biologic.
DESIGN/INTERVENTION:
Five weekly injections of TNFerade biologic, dose-escalated logarithmically from 4 × 10(8) to 4 × 10(11) particle units (PU), were given in combination with cisplatin 75 mg/m(2) and intravenous 5-fluorouracil 1000 mg/m(2)/d for 96 hours on days 1 and 29, and concurrent radiation therapy to 45 Gy. Surgery was performed 9 to 15 weeks after treatment.
SETTING:
U.S. multicenter study.
PATIENTS:
Patients with stage II and III esophageal cancer were enrolled.
MAIN OUTCOME MEASUREMENTS:
Primary outcome measures were safety, feasibility, tolerability, and rate of pCR. Secondary outcome measures were overall survival (OS) and disease-free survival.
RESULTS:
Twenty-four patients with a median age of 61 years were enrolled; 88% of the patients were men, 21% were stage II, and 79% were stage III. Six (29%) had a pCR, observed among 21 patients (20 who underwent esophagectomy and 1 at autopsy). Dose-limiting toxicities were not observed. The most frequent potentially related adverse events were fatigue (54%), fever (38%), nausea (29%), vomiting (21%), esophagitis (21%), and chills (21%). At the top dose of 4 × 10(11) PU, thromboembolic events developed in 5 of 8 patients. The median OS was 47.8 months. The 3- and 5-year OS rates and disease-free survival rates were 54% and 41% and 38% and 38%, respectively.
LIMITATIONS:
We included primarily adenocarcinoma.
CONCLUSIONS:
Preoperative TNFerade, in combination with chemoradiotherapy, is active and safe at doses up to 4 × 10(10) PU and is associated with long survival. This regimen warrants additional studies.

Abstract
PURPOSE OF REVIEW:
This review highlights recent advances in cochlear gene therapy over the past several years. Cochlear gene therapy has undergone tremendous advances over the past decade. Beginning with some groundbreaking work in 2005 documenting hair cell regeneration using virally mediated delivery of the mouse atonal 1 gene, gene therapy is now being explored as a possible treatment for a variety of causes of hearing loss.
RECENT FINDINGS:
Recent advances in cochlear gene therapy include improved methods of gene delivery with a better delineation of viral vectors that are suitable for this purpose, additional improvements in hair cell regeneration, and directed research toward autoimmune hearing loss, ototoxicity, spiral ganglion survival, and genetic forms of hearing loss.
SUMMARY:
If successful, cochlear gene therapy will dramatically alter our ability to treat a variety of forms of acquired and genetic hearing loss.

Je mehr man die Entwicklungen in der Gentherapie der letzten Jahre liest, umso mehr kommt man zu dem Schluss dass wir vor einer medizinischen Revolution stehen, wohl der grössten seit der Entdeckung der Antibiotika.
Man lese sich nur mal die Arbeiten zur Leber´schen Amaurose durch, einer Erkrankung die bislang als nicht behandelbar galt und zur Erblindung führt.

Abstract
Leber congenital amaurosis (LCA) is a severe retinal dystrophy manifesting from early infancy as poor vision or blindness. Loss-of-function mutations in GUCY2D cause LCA1 and are one of the most common causes of LCA, accounting for 20% of all cases. Human GUCY2D and mouse Gucy2e genes encode guanylate cyclase-1 (GC1), which is responsible for restoring the dark state in photoreceptors after light exposure. The Gucy2e(-/-) mouse shows partially diminished rod function, but an absence of cone function before degeneration. Although the cones appear morphologically normal, they exhibit mislocalization of proteins involved in phototransduction. In this study we tested the efficacy of an rAAV2/8 vector containing the human rhodopsin kinase promoter and the human GUCY2D gene. Following subretinal delivery of the vector in Gucy2e(-/-) mice, GC1 protein was detected in the rod and cone outer segments, and in transduced areas of retina cone transducin was appropriately localized to cone outer segments. Moreover, we observed a dose-dependent restoration of rod and cone function and an improvement in visual behavior of the treated mice. Most importantly, cone preservation was observed in transduced areas up to 6 months post injection. To date, this is the most effective rescue of the Gucy2e(-/-) mouse model of LCA and we propose that a vector, similar to the one used in this study, could be suitable for use in a clinical trial of gene therapy for LCA1.
