On the other hand, since you cant establish similarity/interchangeability,
you can't market it as the "generic" version of the branded one in developed

J****a 发帖数: 553 | 5 By my understanding, the DNA or amino acid sequence of the biosimilar
product need not be identical to the innovator product for a finding of
biosimilarity under the statute.There may be advantages to using a different
gene sequence that encodes the same protein.
"In general, FDA expects that the expression construct for a proposed
product will encode the same primary amino acid sequence as the reference

k******n 发帖数: 133 | 8 I disagree with your comments about biosimilar in US. The market is huge and
has a high entry barrier, which scares away all small players. As long as
you can make a "good" biosimilar, you can easily sell at 70% of the
originator's price and earn a decent profit. You can never sell them as
cheap as small generic drugs.

this area. |

N******o 发帖数: 25 | 16 I guess it's OK to have different gene sequence, but final protein sequence
has to be identical, as FDA mentioned. Minor mofification generally referers
to post-translation modification, including glycosylation, C-terminal Lys
truncation for mAb. FDA does gives small rooms for those known modifications
, especially glycosylation. Those have to be justifitable based on bioassay,
preclinical, even clinical data.
Overall, I believe no sequence variation acceptable in term of biosimilar.

d***2 发帖数: 341 | 23 应该都是做trial, 只是biosimilar的regulations跟trial design considerations会
有一点不一样. Biosimilar想当然尔都是跟original product比较, 大概都是做
equivalence or non-inferiority trials (也有做simulation的可能).
如果你已经有相当的pharma experience, 那试试看biosimilar也不错, 拓展新的经验.
Otherwise, 还是先从pharma开始, 学到的经验会更严谨&广泛一些, 当然, 这还跟公
司size, 团队的成熟度以及你自己的各方面能力有关.

一套完整的数据,从质量到临床和一个新药基本没有区别。
所谓biosimilar 的基础是,你不可以比reference product 差,而且,也不可以比它
更好。质量上的“相似”,是减少临床数据的绝对基础,否则就必须当作新药处理。至

高分子,多糖.....进行成分分析(只能这么简单说说了),你去恶补下biosimilar的
基本知识,读读他们关于Enoxaparin的专利和这段历史(包括他们跟FDA 的那些

t**n 发帖数: 4365 | 35 2太不靠谱,一个很强的biosimilar仿制药公司,都需要7-8年
A typical biosimilar takes 7-8 years to develop, at a cost of between USD 75
and 250 million, with clinical trials that may involve about 500 patients.
That compares to 8-10 years for a new drug application, at a cost of USD 800
million, including up to 1000 patients in clinical trials.
如果做不出药,账面上做不出利润,IPO就瞎扯谈了。 |
