基因治疗的概念出现在几十年前,当研究人员推测,人类疾病可以通过精确使用一种技术引入外来DNA来解决遗传缺陷和疾病症状。近年来,基因治疗的进步已经涉足治疗遗传疾病,癌症,神经退行性疾病等各领域。遗传性疾病如色素性视网膜炎等少数眼部疾病的基因也可以如此治疗。公司征集一种在人类眼部组织定性和定量(半)测量体内基因表达的方法。 具体如下https://www.innocentive.com/ar/challenge/9933643 The concept of gene therapy arose decades ago, when researchers postulated that human diseases could be treated by using a technique to introduce foreign DNA to correct genetic defects and disease phenotypes. In recent years, advances in gene therapy have been documented in the treatment of genetic disorders, cancer, and neurodegenerative diseases. Inherited diseases such as retinitis pigmentosa are among a handful of ocular diseases that are amenable to gene therapy. The Seeker desires solutions that will both qualitatively and (semi-) quantitatively measure in vivo gene expression in human ocular tissues. This Challenge requires only a written proposal. Source: InnoCentive Challenge ID: 9933643 Challenge Overview The number of clinical trials for gene therapy to treat ocular disorders is on the rise. Inherited diseases such as retinitis pigmentosa among others are thought to be good candidates for targeted treatment. Currently, there is no method in humans to determine the level or geographic location of transgene expression following administration of gene therapy for diseases of the eye, specifically the retina. The Seeker desires solutions that will both qualitatively and (semi-) quantitatively measure in vivo gene expression in human ocular tissues. Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on June 20, 2015. Late submissions will not be considered. This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the Seeker. To receive an award, Solvers will not be required to transfer their exclusive IP rights to the Seeker. Instead, Solvers will grant to the Seeker a   [更多]

寻找一种载体某些细胞或分子如蛋白质,DNA,RNA,和microRNA,用这些载体来制备高选择性的靶向药物,给药的方法是让药物化合物给药和输送到身体的病灶而达到治疗效果。具体的要求请看下面链接:https://www.innocentive.com/ar/challenge/9933675 AWARD: $30,000 USD | DEADLINE: 2/17/15 | ACTIVE SOLVERS: 108 | POSTED: 1/16/15 Exosomes are membrane-bound vesicles that are produced by many, if not all cell types. Exosomes are able to selectively target certain cells and deliver molecules such as proteins, DNA, RNA, and microRNA. These vesicles are thought to have great potential for targeted drug delivery. The Seeker desires innovative methods for exosome drug loading without significant disruption of the membrane components and properties of the exosome. This Challenge requires only a written proposal. Source: InnoCentive Challenge ID: 9933675 Challenge Overview Drug delivery is the method by which pharmaceutical compounds are administered and transported in the body to achieve therapeutic efficacy. Recently, exosomes have been identified as a novel method to deliver drugs in a targeted manner and their potential is derived from natural components such as specific proteins/lipids contained in the membrane of exosomes. Successful delivery of substantial amounts of therapeutic drugs using exosomes is critically dependent on a highly efficient and broadly applicable methodology for loading exosomes with the therapeutic agent, however at present no such technology is available. The Seeker is looking for one or more technologies that will facilitate exosome drug loading without significant disruption of the membrane components and properties of the exosome.   [更多]

静脉注射的优点就是快速静脉注射药物的分布在整个身体。通常,这些药物总是快速代谢,快速排出,导致短期的临床疗效。大家可以从微丸持续释放显效得皮启发。具体看链接:https://www.innocentive.com/ar/challenge/9933723 Intravenous delivery allows for the rapid distribution of injected drugs from the veins throughout the entire body. Oftentimes, these drugs are quickly metabolized and excreted resulting in short durations of clinical efficacy. Certain therapies may benefit from a bolus followed by sustained release. The Seeker wishes to identify a technology to sustain the delivery of a human high dose intravenous drug from a single injection administered over a period of 15 to 30 minutes. This Challenge requires only a written proposal. Source: InnoCentive Challenge ID: 9933723 Challenge Overview An intravenous sustained drug delivery technology is desired for a high dose drug that needs to be delivered over 8 to 10 hours. This intravenous sustained release delivery technology would allow a bolus of drug (approximately 40 to 60%) to be delivered quickly upon intravenous administration followed by the remaining dose (60 to 40%) delivered in a near zero order fashion from this intravenous administration over an 8 to 10 hour interval. This drug delivery technology needs to use materials that are already recognized as safe or can be easily qualified for parenteral administration in humans. This drug delivery technology should present no encumbrance to nurses administering the drug in a hospital setting. This technology should be amenable to delivering about 2 grams of a drug with an aqueous solubility of approximately 0.75 grams in 50 mL at 25°C and approximately 1 gram in 50 mL at 37°C during the 8 to 10 hour interval. Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on March 21, 2015. Late submissions will not be considered. This is a Theoretical Challenge that requires only a written proposal to be submitted. The Challenge award will be contingent upon theoretical evaluation of the proposal by the   [更多]
