Ex­clu­sive: At Hal Bar­ron’s R&D group at GSK, con­sen­sus is out, lead­ers are in and watch out for an ‘in­tense dri­ve’ to spur the late-stage pipeline

Hal Barron is talking offense. He’s talking teams and leaders. And 9 months into the job of a lifetime running a global, multibillion-dollar R&D shop, he’s got his game plan worked out and his top crew lined up.

Almost literally, it turned out, which I’ll get to later.

“I’m going to empower people,” Barron tells me emphatically, “and they’re going to make important decisions.”

“I feel a sense of urgency,” he says later, returning to a theme in our conversation.

We’re in a conference room on the top floor of an unmarked, mid-19th century Georgian townhouse that’s been refitted as a small operations center just off Berkeley Square in the center of London. Barron, who’s based in the Bay Area, has taken command of it for a few days, summoning members of the inner circle, with roots in San Francisco, the UK and Philadelphia.

I too was summoned, in a way.

Raymond Stevens, Structure Therapeutics CEO

Be­hind Fri­day's $161M IPO: A star sci­en­tist, GPCR drug dis­cov­ery and a plan to chal­lenge phar­ma in di­a­betes

What does it take to pull off a $161 million biotech IPO these days?

In Structure Therapeutics’ case, it means having a star scientist co-founder paired with the computational drug discovery company Schrödinger, $198 million in private funding from blue-chip investors, almost six years of research work on G protein-coupled receptors and a slate of oral, small-molecule drugs, with an eye on the huge and growing diabetes and weight-loss market.

Ma­gen­ta halts stem cell work and may sell it­self fol­low­ing pa­tient death, clin­i­cal hold

Magenta Therapeutics said it is halting work on its stem cell transplant drug pipeline and may sell itself, a week after the company reported the death of a patient in an early stage trial of its antibody-drug conjugate.

The Cambridge, MA-based company said it will conduct a “review of strategic alternatives,” and that could include an “acquisition, merger, business combination, or other transaction.”

In­fla­tion re­bates in­com­ing: Wyden calls on CMS to move quick­ly as No­var­tis CEO pledges re­ver­sal

Senate Finance Chair Ron Wyden (D-OR) this week sent a letter to the head of the Centers for Medicare & Medicaid Services seeking an update on how and when new inflation-linked rebates will take effect for drugs that see major price spikes.

The newly signed Inflation Reduction Act requires manufacturers to pay a rebate to Medicare when they increase drug prices faster than the rate of inflation.

Trodelvy notch­es a win in most com­mon form of breast can­cer

Following a promise last year to go “big and fast in breast cancer,” Gilead has secured a win for Trodelvy in the most common form.

The drug was approved to treat HR-positive, HER2-negative breast cancer patients who’ve already received endocrine-based therapy and at least two other systemic therapies for metastatic cancer, Gilead announced on Friday.

Trodelvy won its first indication in metastatic triple-negative breast cancer back in 2020, and has since added urothelial cancer to the list. HR-positive HER2-negative breast cancer accounts for roughly 70% of new breast cancer cases worldwide per year, according to senior VP of oncology clinical development Bill Grossman, and many patients develop resistance to endocrine-based therapies or worsen on chemotherapy.

John Roberts, exiting Vyant Bio CEO

Neu­rode­gen­er­a­tive biotech Vyant warns of po­ten­tial wind-down

The CEO and chief scientific officer of Vyant Bio are out the door as the little-known but publicly-listed neurodegenerative biotech searches for an exit or, if all else fails, a wind-down.

The soul-searching bookends a winding journey for the biotech, which rebranded and transitioned from diagnostics company Cancer Genetics in 2021 after a merger with StemoniX. That came after a failed merger attempt with NovellusDx (now Fore Biotherapeutics) in 2018. In the last few years, units have been sold off and the stock price $VYNT has plummeted from the $30 range to penny stock territory.

Sanofi scraps PhI­II tri­al for Prin­cip­ia drug af­ter re­view­ing com­pe­ti­tion

Months after the FDA placed Phase III trials of Sanofi’s BTK inhibitor on hold, the company is winding down one of the studies.

Sanofi reported in its Q4 earnings that the URSA study “was discontinued after careful evaluation of the emerging competitive treatment landscape in” myasthenia gravis, a rare disease that causes muscle weakness.

The Phase III, placebo-controlled trial was testing tolebrutinib in patients with the moderate-to-severe form of the disease. It started in late 2021, according to records on clinicaltrials.gov, and was originally designed to recruit 154 participants who were receiving the standard of care.

Medicago's vaccine greenhouse (Medicago via YouTube)

Cana­di­an plant-based vac­cine de­vel­op­er Med­ica­go shut­ters months af­ter lay­offs

Plant-based Covid-19 vaccine developer Medicago shut down this week with little fanfare. And its two subsidiaries, Medicago R&D and Medicago USA, are also closing their doors, according to a company news release.

The lone shareholder left standing, Japan-based Mitsubishi Chemical Group, “has determined not to make further investments in Medicago and to proceed with an orderly wind-up of its business and operations in Canada and in the United States.”

Af­ter 13 years, Ramy Mah­moud steps in­to CEO seat at Opti­nose; Ru­pert Vessey set to ex­it Bris­tol My­ers in Ju­ly

After 13 years as president and COO at Optinose, Ramy Mahmoud has stepped into a new role as its CEO. He is taking the place of Peter Miller, who stepped down earlier this week, though Miller is still staying with the company as a consultant.

In 2010, the two business partners joined Optinose to take it in a new direction, transforming it from a delivery platform to product company. They previously worked together at Johnson & Johnson, when Miller was president at Janssen and Mahmoud headed medical affairs. Miller said after he learned about Optinose, “I did what I always do, which is find people smarter than me to talk with about the idea. And the first person I called was Ramy … and I said, ‘Hey, Ramy, what do you think of this technology?’”
