近期的收獲: 原來接觸過補(bǔ)充資料,基本上是按照補(bǔ)充資料通知中提到的內(nèi)容,逐項完善,最后按照要求提交資料。 近期接觸了幾個臨床批件,發(fā)現(xiàn)好幾個產(chǎn)品都提到讓進(jìn)一步完善降解產(chǎn)物與降解途徑的研究,反觀補(bǔ)充資料期間也提到過類似的問題,當(dāng)時也已經(jīng)按照要求完善了,經(jīng)咨詢專家,得到的回復(fù)是主要的降解產(chǎn)物要制備、結(jié)構(gòu)確證并進(jìn)行研究,言外之意大家自己琢磨吧。 |

前不久學(xué)習(xí)了一下insight數(shù)據(jù)庫,對藥品的審評進(jìn)度查詢及集中審評的品種等都有詳細(xì)的介紹,但因為是收費(fèi)的,所以感覺不是很好,通過小木蟲及百度等等方面的學(xué)習(xí),發(fā)現(xiàn)其實自己也可以查到某個品種的審評進(jìn)度,即使在不知道受理號的情況下,分享一下給大家,雖然我也屬于菜鳥級別 愿共同進(jìn)步:1.CDE官網(wǎng)/信息公開/收審情況--受審目錄瀏覽(通過品種名稱及申報類型鎖定要查的大概內(nèi)容),接下來會有許多條信息展示,可根據(jù)前面的任一受理號進(jìn)行如下2步操作,查到是哪個廠家的品種; 2.藥監(jiān)總局首頁最下端--行政事項受理/輸入受理號即可 3.CDE官網(wǎng)/信息公開/收審情況--新報任務(wù)公示,輸入受理號及申報類型,就可以看到該品種當(dāng)前的審評進(jìn)度了。 |

相信論壇里做仿制藥的相對多一點,F(xiàn)DA中關(guān)于Generic Drug的指導(dǎo)原則這么多,大家都可以就其中一篇發(fā)表下學(xué)習(xí)收獲等…… Generic Drug Issued Date 180-Day Exclusivity When Multiple Abbreviated New Drug Applications Are Submitted on the Same Day (I) 8/1/2003 Abbreviated New Drug Applications: Impurities in Drug Products 11/29/2010 Alternate Source of Active Pharmaceutical Ingredients in Pending ANDAs (I) 12/12/2000 ANDAs: Impurities in Drug Substances; Chemistry, Manufacturing and Controls Information (I) 7/15/2009 ANDAs: Pharmaceutical Solid Polymorphism; Chemistry, Manufacturing and Controls Information (I) 7/9/2007 ANDAs: Stability Testing of Drug Substances and Products, Questions and Answers 5/15/2014 ANDA Submissions – Amendments and Easily 7/10/2014 ANDA Submissions – Prior Approval Supplements Under GDUFA 7/10/2014 ANDA Submissions -- Refuse-to-Receive Standards 9/16/2014 Controlled Correspondence Related to Generic Drug Development 8/26/2014 Court Decisions, ANDA Approvals, and 180-Day Exclusivity Under the Hatch-Waxman Amendments to the Federal Food, Drug, and Cosmetic Act (I) 3/30/2000 Handling and Retention of Bioavailability and Bioequivalence Testing Samples (I) 5/26/2004 Individual Product Bioequivalence Recommendations - List of Product Bioequivalence Recommendations (I) 6/11/2010 Letter announcing that the OGD will now accept the ICH long-term storage conditions as well as the stability studies conducted in the past (I)8/18/1995 Letter describing efforts by the CDER & the ORA to clarify the responsibilities of CDER chemistry review scientists and ORA field investigators in the new & abbreviated drug approval process in order to reduce duplication or redundancy in the process (I) 10/14/1994 Letter on incomplete Abbreviated Applications, Convictions Under GDEA, Multiple Supplements,Annual Reports for Bulk Antibiotics, Batch Size for Transdermal Drugs, Bioequivalence Protocols, Research, Deviations from OGD Policy (I) 4/8/1994 Letter on the provision of new information pertaining to new bioequivalence guidelines and refuse-to-file letters (I) 7/1/1992 Letter on the provision of new procedures and policies affecting the generic drug review process (I) 3/15/1989 Letter on the request for cooperation of regulated industry to improve the efficiency and effectiveness of the generic drug review process, by assuring the completeness and accuracy of required information and data submissions (I) 11/8/1991 Letter on the response to 12/20/84 letter from the Pharmaceutical Manufacturers Association about the Drug Price Competition and Patent Term Restoration Act (I) 3/26/1985 Letter to all ANDA and AADA applicants about the Generic Drug Enforcement Act of 1992 (GDEA), and the Office of Generic Drugs intention to refuse-to-file incomplete submissions as required by the new law (I) 1/15/1993 Letter to regulated industry notifying interested parties about important detailed information regarding labeling, scale-up, packaging, minor/major amendment criteria, and bioequivalence requirements (I) 8/4/1993 Major, Minor, and Telephone Amendments to Abbreviated New Drug Applications (I) 12/21/2001 Revising ANDA Labeling Following Revision of the RLD Labeling (I) 4/25/2000 Size, Shape, and Other Physical Attributes of Generic Tablets and Capsules 12/10/2013 Submission of Summary Bioequivalence Data for Abbreviated New Drug Applications (I) 5/6/2011 Variations in Drug Products that May Be Included in a Single ANDA (I) 1/27/1999 |

化學(xué)藥品仿制藥國內(nèi)趨勢分析【原創(chuàng)】: 全局:首先要強(qiáng)調(diào)的是,一場超級大風(fēng)暴即將在我國的化藥行業(yè)發(fā)生,國內(nèi)化藥企業(yè)將進(jìn)入到大洗牌階段,對于小企業(yè)而言將是災(zāi)難性的,然而生存下來的將會有不錯且穩(wěn)定的收入。既是挑戰(zhàn),更是機(jī)遇。迎難而上,冷靜分析,積極準(zhǔn)備,亂世出英雄。小型藥企可以通過幾個特色的產(chǎn)品成長起來,大藥企將更強(qiáng)大!筆者希望這將是中國制藥行業(yè)質(zhì)變的開始! 文號方面:化學(xué)仿制藥較多的企業(yè)將面臨巨大的壓力,手里攥著幾百個文號企業(yè)與只有幾十個文號的企業(yè)差別不大,因為幾年以后大部分的文號將變成一疊廢紙,原本可以炫耀的文號數(shù)量,將變成現(xiàn)在巨大的壓力,僵尸文號將越來越少。仿制藥也將走精品路線,每個品種也許只有幾家優(yōu)質(zhì)的企業(yè)生產(chǎn),但這樣足夠了,對藥企來說價格上去了,需求量穩(wěn)定,藥企也將獲得該有的收入,對于制藥市場來說也是斷臂求生的機(jī)會,提升整體行業(yè)質(zhì)量,提升我國制藥的水平,提升患者對國產(chǎn)藥品的信心,造福大眾。 藥品價格方面:未來幾年內(nèi),隨著研發(fā)成本(工藝優(yōu)化、質(zhì)量一致性評價)的持續(xù)增加,仿制藥的價格將會有較大幅度的增長,為數(shù)不多的生產(chǎn)企業(yè)不太會惡性競爭,更可能是劃江而治,實現(xiàn)共贏。 制劑方面:面對現(xiàn)在仿制藥精品化的大趨勢,未來制劑將是重中之重,尋找可靠的、能力強(qiáng)的研發(fā)合作單位也將勢必成為熱點。因為現(xiàn)在大部分廠家的仿制藥制劑是通不過接下來的一致性評價,必須改工藝方有一線生計?煽康墓に,才有可靠的產(chǎn)品。制劑行業(yè)必將大爆發(fā)。 臨床研究機(jī)構(gòu):鑒于今年1622個項目的自查,多家知名的臨床試驗機(jī)構(gòu)深陷其中,有的更是被立案調(diào)查,將對之前所做的不合格的臨床試驗負(fù)責(zé),懲罰也是想當(dāng)嚴(yán)重的。就目前來看,很多臨床機(jī)構(gòu)都不愿意去接臨床項目,或者有選擇的去接受項目。且臨床研究的費(fèi)用將會越來越高,要求越來越嚴(yán)。那么,對于即將到來的質(zhì)量一致性評價的BE研究,全國大約十幾萬的文號就算是一小部分做BE研究,也是一個工作量無比巨大的工作,全國的臨床科研機(jī)構(gòu)根本不夠,故競爭又將非常激烈。費(fèi)用將會從目前的一百多萬,起碼漲到兩百多萬。這對于小型企業(yè)來說,又是壓力巨大;而大企業(yè)就更具有優(yōu)勢。故聯(lián)系可靠的、關(guān)系穩(wěn)定的臨床研究機(jī)構(gòu),將是工作重點之一。 新藥研發(fā)方面:未來幾年內(nèi),對于化藥新藥的研究將進(jìn)入一個寒冬,企業(yè)都被質(zhì)量一致性評價忙的無暇顧及,原有文號的保留和強(qiáng)化是藥企的根本,而目前化藥的研發(fā)難度較大,在未來幾年大洗牌的時代將不會有大突破。 中藥方面:由于化藥行業(yè)生存的壓力增大,會有更多的廠家將發(fā)力到相對穩(wěn)定的中藥行業(yè),而現(xiàn)有成熟的中藥品種將變成香餑餑。但也只適合有中藥研發(fā)基礎(chǔ)的企業(yè)。 |

活動很簡單,大家不要想太復(fù)雜噢,不用長篇大論,可以分享下最近掌握的小技巧之類的,或者簡單的一些經(jīng)驗吧。 示例: 以前知道drugfuture可以查找化合物的合成工藝路線,通過引用的專利來追溯原研的化合物專利等等。 最近發(fā)現(xiàn)藥渡網(wǎng)也是個不錯的網(wǎng)站,除了總結(jié)出一些經(jīng)典的工藝路線,還對批準(zhǔn)上市的藥物中的雜質(zhì)進(jìn)行了列舉,包括雜質(zhì)的化合物結(jié)構(gòu)哦。對于做仿制藥的立項調(diào)研,或者對于申報資料中3.2.S.2.6中工藝路線的選擇都有非常不錯的借鑒價值。 |

支持支持,版內(nèi)蟲友參與積極分享以及討論的熱情不是很高。我覺得需要多舉行相關(guān)的交流分享活動,聯(lián)絡(luò)一群愿意交流分享并為小木蟲的新藥研發(fā)板塊良好發(fā)展盡微薄之力的蟲蟲。 版主更應(yīng)該帶頭,金幣就不要吝嗇了。 ![]() |
