Financings have been a hot topic this spring for Russo Partners as multiple companies with which we work secured venture capital funding to advance clinical programs. Below are more details about each company’s announcement, including the planned use of the funds and sample media coverage.
Alder BioPharmaceuticals

In April, Alder BioPharmaceuticals raised $38 million in a Series D financing that will accelerate the development of its pipeline of antibody therapeutics, including ALD403, a calcitonin gene-related peptide (CGRP)-inhibiting antibody for the treatment of migraine, as well as ALD518, an IL-6-inhibiting antibody that is currently in Phase 2 clinical studies for cancer-related indications. Alder retained the rights to develop ALD518 in cancer-related indications as part of a partnership formed with Bristol-Myers Squibb in 2009.
The round was led by new investor Novo Ventures and joined by existing investors Sevin Rosen Funds, Ventures West, HIG Ventures, TPG Biotech, Delphi Ventures and WRF Capital. Read more about this announcement in the following article from Xconomy and news brief from Fortune.
