Say good­bye to plants: Syn­bio play­er An­theia earns new back­ers in quest to re­design flo­ra-de­rived med­i­cine man­u­fac­tur­ing

The age of syn­thet­ic bi­ol­o­gy is of­fi­cial­ly up­on us with su­per-uni­corns like Gink­go Bioworks chang­ing the game in terms of how in­vestors view those cell en­gi­neer­ing plat­forms. Now, a Cal­i­for­nia com­pa­ny look­ing to do away with frag­ile flo­ra sup­ply chains in drug de­vel­op­ment has earned a new round of in­vest­ment to chase its goal.

Syn­bio play­er An­theia raised a $73 mil­lion Se­ries B round it will use to ad­vance its pipeline of com­pounds de­rived from a plant-al­ter­na­tive man­u­fac­tur­ing process us­ing whole yeast cell en­gi­neer­ing, the com­pa­ny said Wednes­day.

The round was led by Viking Glob­al In­vestors and in­clud­ed par­tic­i­pa­tion from Sher­pa­lo Ven­tures and Hill­spire.

An­theia will aim to en­gi­neer and ad­vance its first phar­ma­ceu­ti­cal com­pound de­vel­oped through its yeast cell fer­men­ta­tion process as well as a range of key start­ing ma­te­ri­als (KSM) and API, it said. Many of those pre­cur­sor com­pounds are de­rived from plants with a sup­ply chain An­theia de­scribed as “frag­ile” giv­en en­vi­ron­men­tal threats, in­clud­ing nat­ur­al dis­as­ters and geopo­lit­i­cal con­flict.

The com­pa­ny’s en­gi­neer­ing plat­form would, in the­o­ry, re­place the need for com­plex plant-de­rived com­pounds al­to­geth­er, us­ing en­gi­neered yeast cells act­ing like a “minia­ture fac­to­ry” to churn out mol­e­cules at com­mer­cial scale. The com­pa­ny has some ear­ly da­ta back­ing up its claims, with its first en­gi­neered KSM run­ning at what the biotech calls “com­mer­cial­ly rel­e­vant titers” at the pi­lot scale.

Mean­while, An­theia has achieved biosyn­the­sis in four class­es of plant-de­rived med­i­cines, it said, in­clud­ing tropane al­ka­loids, the process of which was doc­u­ment­ed in a Sep­tem­ber ar­ti­cle from CEO Christi­na Smolke in Na­ture. Those drugs, which are used to treat neu­ro­mus­cu­lar dis­or­ders such as Parkin­son’s and mus­cle spasms, re­ly on the “in­ten­sive cul­ti­va­tion” of night­shades, An­theia said, due to the fact that there is no com­mer­cial-scale chem­i­cal syn­the­sis process avail­able.

The sup­ply chain for tropane al­ka­loids, in­clud­ing the an­timus­carinic agent at­ropine used to re­duce sali­va­tion be­fore surgery and an­ti-nau­sea patch­es made with scopo­lamine, is par­tic­u­lar­ly vul­ner­a­ble to dis­rup­tion, mak­ing it a ripe tar­get for An­theia’s plat­form. To repli­cate the drugs, An­theia’s yeast plat­form had to ex­press 26 genes de­rived from 10 or­gan­isms with eight gene dele­tions, un­der­scor­ing the com­plex­i­ty of those drugs and An­theia’s en­gi­neer­ing pow­er.

“An­theia’s syn­thet­ic bi­ol­o­gy plat­form can pre­vent drug short­ages by en­abling more re­silient and ag­ile pro­duc­tion of es­sen­tial med­i­cines for the US and glob­al mar­kets, solv­ing one of the most chal­leng­ing prob­lems in the in­dus­try and im­prov­ing the over­all health­care sys­tem,” Smolke said in a state­ment.

The three oth­er plant-de­rived med­i­cine class­es where An­theia has achieved biosyn­the­sis in­clude an­ti­tus­sives, chemother­a­peu­tics, and neu­ro­trans­mit­ter in­hibitors. Mean­while, the com­pa­ny has eyes on “un­drug­gable” class­es of ther­a­peu­tics giv­en the po­ten­tial to crack open ar­eas of drug en­gi­neer­ing where chem­i­cal syn­the­sis isn’t pos­si­ble.

Syn­bio plat­forms have come a long way in re­cent years as com­pa­nies that once couldn’t hold in­vestors’ at­ten­tion are now scor­ing mas­sive pub­lic of­fer­ings and fundrais­ing rounds.

The largest, by far, is Gink­go Bioworks, which went pub­lic in May as part of a re­verse merg­er that val­ued the com­pa­ny pre-mon­ey at a whop­ping $15 bil­lion. Gink­go scrapped for years to earn that val­u­a­tion, work­ing on ar­eas as di­verse as per­fume and syn­thet­ic meat be­fore their com­mer­cial-scale drug man­u­fac­tur­ing process went vi­ral.

Mean­while, com­pa­nies like Zymer­gen, us­ing cell fer­men­ta­tion to pro­duce in­dus­tri­al ma­te­ri­als, are al­so see­ing a wave of new in­ter­est. The biotech closed a $500 mil­lion IPO in April with the am­bi­tious goal of us­ing its plat­form to dis­rupt a po­ten­tial $3 bil­lion in­dus­tri­al ma­te­ri­als mar­ket.

De­spite falling Covid-19 sales, BioN­Tech main­tains '22 sales guid­ance

While Pfizer raked in almost $28 billion last quarter, its Covid-19 vaccine partner BioNTech reported a rise in total dose orders but a drop in sales.

The German biotech reported over $3.2 billion in revenue in Q2 on Monday, down from more than $6.7 billion in Q1, in part due to falling Covid sales. While management said last quarter that they anticipated a Covid sales drop — CEO Uğur Şahin said at the time that “the pandemic situation is still very much uncertain” — Q2 sales still missed consensus by 14%.

Up­dat­ed: Pfiz­er scoops up Glob­al Blood Ther­a­peu­tics and its sick­le cell ther­a­pies for $5.4B

Pfizer is dropping $5.4 billion to acquire Global Blood Therapeutics.

Just ahead of the weekend, word got out that Pfizer was close to clinching a $5 billion buyout — albeit with other potential buyers still at the table. The pharma giant, flush with cash from Covid-19 vaccine sales, apparently got out on top.

The deal immediately swells Pfizer’s previously tiny sickle cell disease portfolio from just a Phase I program to one with an approved drug, Oxbryta, plus a whole pipeline that, if all approved, the company believes could make for a $3 billion franchise at peak.

With drug pric­ing al­most done, Con­gress looks to wrap up FDA user fee leg­is­la­tion

The Senate won’t return from its summer recess until Sept. 6, but when it does, it officially has 18 business days to finalize the reauthorization of the FDA user fee programs for the next 5 years, or else thousands of drug and biologics reviewers will be laid off and PDUFA dates will vanish in the interim.

FDA commissioner Rob Califf recently sent agency staff a memo explaining how, “Our latest estimates are that we have carryover for PDUFA [Prescription Drug User Fee Act], the user fee funding program that will run out of funding first, to cover only about 5 weeks into the next fiscal year.”

As­traZeneca and Dai­ichi Sankyo sprint to mar­ket af­ter FDA clears En­her­tu in just two weeks

Regulators didn’t keep AstraZeneca and Daiichi Sankyo waiting long at all for their latest Enhertu approval.

The partners pulled a win on Friday in HER2-low breast cancer patients who’ve already failed on chemotherapy, just two weeks after submitting a supplemental BLA. While this isn’t the FDA’s fastest approval — Bristol Myers Squibb won an OK for its blockbuster checkpoint inhibitor Opdivo in just five days back in March — it comes well ahead of Enhertu’s original Q4 PDUFA date.

Amgen had hoped that its latest study matching its landmark KRAS G12C drug Lumakras with checkpoint inhibitors would open up its treatment horizons and expand its commercial potential. Instead, the combo spurred safety issues that blunted efficacy and forced the pharma giant to alter course on its treatment strategy, once again disappointing analysts who have been tracking the drug’s faltering sales and limited therapeutic reach.

Ab­b­Vie sur­veys emo­tion­al im­pact of chron­ic leukemia con­di­tion, finds 'roller coast­er' of emo­tions

Rare diseases often have more than just physical effects on patients — especially when it comes to chronic conditions. In the case of the rare slow-growing blood cancer chronic lymphocytic leukemia (CLL), AbbVie wanted to try to assess the mental and emotional toll on patients.

So it surveyed more than 300 CLL patients, caregivers and physicians. While each group differed in how they felt — caregivers overwhelmingly (81%) felt positive about their role, for instance — patients described a “roller coaster” of emotions traversing diagnosis to treatment to remission and even relapse for some.

Bernhardt Zeiher, outgoing Astellas CMO (Astellas)

Q&A: Astel­las' re­tir­ing head of de­vel­op­ment re­flects on gene ther­a­py deaths

For anyone who’s been following discussions about the safety alarms surrounding the adeno-associated viruses (AAV) commonly used to deliver gene therapy, Astellas should be a familiar name.

The Japanese pharma — which bought out Audentes Therapeutics near the end of 2019 and later built a gene therapy unit around the acquisition — rocked the field when it reported three patient deaths in a trial testing AT132, the lead program from Audentes designed to treat a rare muscle disease called X-linked myotubular myopathy (XLMTM).

When the company restarted the trial, it adjusted the dose and instituted a battery of other measures to try to prevent the same thing from happening again. But tragically, the first patient to receive the new regimen died just weeks after administration. The therapy remains under clinical hold, and just weeks ago, Astellas flagged another safety-related hold for a separate gene therapy candidate. In the process of investigating the deaths, the company has also taken flak about the way it disclosed information.

Big questions remain — questions that can have big implications about the future of AAV gene therapies.

Bernhardt Zeiher did not imagine any of it when he first joined Astellas as the therapeutic area leader in inflammation, immunology and infectious diseases. But his ascent to chief medical officer and head of development coincided almost exactly with Astellas’ big move into gene therapy, putting him often in the driver’s seat to grapple with the setbacks.

As Zeiher prepares to retire next month after a 12-year tenure — leaving the unfinished tasks to his successor, a seasoned cancer drug developer — he chatted with Endpoints News, in part, to discuss the effort to understand what happened, lessons learned and the criticism along the way.

The transcript has been lightly edited for length and clarity.

Endpoints: I want to also ask you a bit about the gene therapy efforts you’ve been working on. Astellas has really been at the forefront of discovering the safety concerns associated with AAV gene therapy. What’s that been like for you?

Zeiher: Well, I have to admit, it’s been a bit of a roller coaster. We acquired Audentes. Huge amount of enthusiasm. What we saw with AT132 — that was the lead program in XLMTM — was just remarkable efficacy. I mean, kids who went from being on ventilators, not able to eat for themselves, sit up, do things like that, to off ventilators, walking, you know, really — one investigator called it this Lazarus-like effect. It was just really dramatic efficacy. And then to have the safety events that occurred. So they actually occurred within that first year of the acquisition. So we had the three patient deaths. Me and my organization became very, very much involved. In fact, Ed Conner, who had been the chief medical officer, he left after some of the deaths, but I stepped in as the kind of acting chief medical officer, we had another chief medical officer who was involved, and then we had a fourth death, and I became acting again for a period of time.
