Which clinical step is omitted for biosimilar agents?

1 answer:

4 0

There are normally four steps to approve (or not ) a medicine:
step 1: it must be proven that this drug is not toxic
step 2: it must be proven that this drug is active on sick people
step 3: it is compared to other drugs which have the same indication
step 4: is the pharmacovigilance. The drug is monitored during all its commercialization.

During the approval of biosimilar agents, step 2 is omitted because we need to establish that there are “no clinically meaningful differences” in the efficacy and safety of the biosimilar when compared to the original, which can be done in step 3.

Valentin [98]

Answer:

a. hox genes.

Explanation:

HOX genes have the following functions:

HOX genes are the homeobox subset.

They specify the areas of the embryo's body plan along the animal head-tail axis.

They are encoding Hox proteins that specify the position characteristics and ensure that the right structures form at the right position in the body.

They regulate high-level executive genes, such as transcription factors and intracellular signaling molecules, which adhere, number, form, and growth to cells.

The vertebrates are highly preserved.

The clusters and other genes occur uninterrupted.

Evolutionary, the heterogeneous regulatory areas between the genes most previously present are larger and more preserved than those present at the other ends of the clusters.

The characteristical feature is that these are homeodomain proteins with a highly preserved area of DNA binding encoded with homeobox gens.

OleMash [197]

Answer:

Bubbles are a sign that the yeast is alive, and that it is performing anaerobic respiration. You should notice that the mixtures with too little and too much sugar do not grow, bubble or foam properly. This is because the yeast needs the perfect amount in order to produce carbon dioxide.
