Gilead Sciences CEO Daniel O’Day has spoken openly about acquisitions as a way to build up the company’s drug pipeline. This week, it made its biggest buy yet.
The $21 billion Immunomedics acquisition brings to Gilead a cancer drug that many analysts project will become a blockbuster seller. Some of those analysts think Gilead might have overpaid but the company says there were competing offers. The drug, sacitizumab govitecan (Trodelvy), is what’s called an antibody drug conjugate (ADC). This drug class has seen a lift in recent years. Four years ago, there were just three FDA-approved ADCs. The FDA has approved five ADCs since June 2019. It’s easy to forget, but the Immunomedics drug almost ended up in the hands of ADC specialist Seattle Genetics, which struck a deal for its rights in 2017 but then backed away amid shareholder opposition and litigation.
SeaGen (NASDAQ: SGEN) has since had better dealmaking luck. This week the Bothell, WA-based company struck two deals with Merck; in the larger one, the pharmaceutical giant is paying $600 million cash and making a $1 billion equity investment to begin a partnership to co-develop a SeaGen ADC. This week also brought news of startups emerging from stealth, corporate shakeups at two biotechs, and more life science IPOs. Let’s get to those stories in this week’s roundup.
LET’S MAKE A DEAL
—Gilead Sciences (NASDAQ: GILD) agreed to pay $21 billion to acquire Immunomedics (NASDAQ: IMMU) and its FDA-approved triple negative breast cancer drug sacitizumab govitecan, which is being studied for applications in other cancers.

—Qiagen (NYSE: QGEN) is paying $238 million to acquire the 80.1 percent of NeuMoDx Molecular that it doesn’t already own. Ann Arbor, MI-based NeuMoDx makes diagnostics instruments based on PCR technology.
—Vertex Pharmaceuticals (NASDAQ: VRTX) is paying Moderna (NASDAQ: MRNA) $75 million up front to kick off a three-year research collaboration focused on discovering and developing lipid nanoparticles and messenger RNAs that can deliver gene-editing therapies to the lungs for potential applications in cystic fibrosis (CF). The companies previously teamed up in lung and CF research in 2016.

—Boehringer Ingelheim inked a deal for rights to a Click Therapeutics mobile app that will be developed as a digital therapeutic for schizophrenia. Germany-based Boehringer Ingelheim is paying Click an unspecified upfront payment plus research funding. The New York startup is potentially eligible for milestone payments in a deal whose total value could reach up to $500 million.
—AstraZeneca (NYSE: AZN) is acquiring from Dogma Therapeutics an oral version of a type of cholesterol-lowering drug called a PCSK9 inhibitor. Currently available PCSK9 drugs are injectable. Cambridge, MA-based Dogma will receive an unspecified upfront payment plus additional payments tied to the progress of the preclinical compound.

—Cassava Sciences (NASDAQ: SAVA) reported encouraging data from a 64-patient placebo-controlled Phase 2 study testing sumifilam, an Alzheimer’s disease drug designed to restore the brain protein filamin A. The Austin, TX-based company said 98 percent of those who received the small molecule drug showed a response, including improvements in memory and cognition.
THIS WEEK IN BIOTECH IPOS
—Athira Pharma raised $204 million from its IPO, which priced at $17 per share, the top of its projected price range.
