Cana­di­an biotech to dis­con­tin­ue omega-3 pro­gram af­ter sec­ond PhI­II fails on sig­nif­i­cant triglyc­eride re­duc­tion

It’s been an event­ful 12 months or so for the omega-3 mar­ket, but one com­pa­ny’s lat­est at­tempt to use the ap­proach for se­vere hy­per­triglyc­eridemia came up short.

Cana­di­an biotech Acasti Phar­ma $AC­ST re­port­ed a sec­ond Phase III flop for its omega-3 phos­pho­lipid can­di­date CaPre on Mon­day, as the tri­al did not reach sta­tis­ti­cal sig­nif­i­cance for its pri­ma­ry end­point. The com­pa­ny stat­ed that, as a re­sult, it will not file for an NDA in the US nor con­duct ad­di­tion­al tri­als for the pro­gram.

“We are very dis­ap­point­ed in the out­come of the Tril­o­gy 2 study,” Acasti CEO Jan D’Alvise said in a state­ment. “While the triglyc­eride re­duc­tion ob­served in the con­trol arm was less than what was ob­served in the Tril­o­gy 1 Study, it still re­mains one of the high­est seen amongst the pre­vi­ous­ly con­duct­ed triglyc­eride re­duc­tion stud­ies.”

Acasti shares, which were al­ready in pen­ny-stock ter­ri­to­ry, fell 65% Mon­day fol­low­ing the news.

The com­pa­ny had been con­duct­ing two Phase III tri­als in par­al­lel, and af­ter Acasti re­port­ed that the first study didn’t hit sta­tis­ti­cal sig­nif­i­cance in Jan­u­ary, a path for­ward might still have re­mained had Mon­day’s re­sults proved more promis­ing. How­ev­er, that didn’t hap­pen, as both stud­ies saw “un­usu­al” triglyc­eride re­duc­tions in their place­bo arms.

Mon­day’s re­sults (“Tril­o­gy 2”) showed a 17.9% me­di­an re­duc­tion in triglyc­eride lev­els among pa­tients re­ceiv­ing place­bo at 12 weeks, as com­pared to 27.5% in the first Phase III (“Tril­o­gy 1”). Al­so, Acasti re­port­ed a 30.4% me­di­an re­duc­tion in triglyc­eride lev­els among all pa­tients re­ceiv­ing CaPre, as com­pared to the ear­li­er tri­al’s 30.5% rate.

That led to a p-val­ue of 0.19 for the un­ad­just­ed, place­bo-cor­rect­ed triglyc­eride re­duc­tion of 12.4%. Er­go, not sta­tis­ti­cal­ly sig­nif­i­cant.

The un­usu­al triglyc­eride re­duc­tion in the first Phase III spurred an au­dit of five test­ing sites which Acasti said in Feb­ru­ary dis­pro­por­tion­ate­ly con­tributed to the place­bo re­sponse. But in the sec­ond Phase III, the com­pa­ny be­lieves the tri­al “was like­ly not af­fect­ed by the same ‘Pre-Ran­dom­iza­tion Triglyc­eride Nor­mal­iza­tion’ ef­fect that we saw in Tril­o­gy 1,” D’Alvise said.

Fish oil omega-3 drugs have had their fair share of the spot­light re­cent­ly thanks to a patent fight be­tween the biotech Amarin and gener­ic drug­mak­ers. Af­ter Amarin re­ceived a block­buster FDA ap­proval last De­cem­ber for ex­pand­ing the use of Vas­cepa in­to pa­tients with el­e­vat­ed triglyc­eride lev­els, a US Dis­trict Court in­val­i­dat­ed the com­pa­ny’s IP in March.

Soon there­after, the FDA ap­proved the first Vas­cepa gener­ic in May, a copy of pure EPA from Hik­ma Phar­ma­ceu­ti­cals. But an­a­lysts at the time not­ed that a Hik­ma launch was not like­ly to take place any time soon giv­en the risks of a po­ten­tial suc­cess­ful ap­peal by Amarin.

Biotech Half­time Re­port: Af­ter a bumpy year, is biotech ready to re­bound?

The biotech sector has come down firmly from the highs of February as negative sentiment takes hold. The sector had a major boost of optimism from the success of the COVID-19 vaccines, making investors keenly aware of the potential of biopharma R&D engines. But from early this year, clinical trial, regulatory and access setbacks have reminded investors of the sector’s inherent risks.

RBC Capital Markets recently surveyed investors to take the temperature of the market, a mix of specialists/generalists and long-only/ long-short investment strategies. Heading into the second half of the year, investors mostly see the sector as undervalued (49%), a large change from the first half of the year when only 20% rated it as undervalued. Around 41% of investors now believe that biotech will underperform the S&P500 in the second half of 2021. Despite that view, 54% plan to maintain their position in the market and 41% still plan to increase their holdings.

No­var­tis de­vel­op­ment chief John Tsai: 'We go deep in the new plat­form­s'

During our recent European Biopharma Summit, I talked with Novartis development chief John Tsai about his experiences over the 3-plus years he’s been at the pharma giant. You can read the transcript below or listen to the exchange in the link above.

John Carroll: I followed your career for quite some time. You’ve had more than 20 years in big pharma R&D and you’ve obviously seen quite a lot. I really was curious about what it was like for you three and a half years ago when you took over as R&D chief at Novartis. Obviously a big move, a lot of changes. You went to work for the former R&D chief of Novartis, Vas Narasimhan, who had his own track record there. So what was the biggest adjustment when you went into this position?

As­traZeneca on­col­o­gy R&D chief Su­san Gal­braith: 'Y­ou're go­ing to need or­thog­o­nal com­bi­na­tion­s'

 

Earlier in the week we broadcast our 4th annual European Biopharma Summit with a great lineup of top execs. One of the one-on-one conversations I set up was with Susan Galbraith, the oncology research chief at AstraZeneca. In a wide-ranging discussion, Galbraith reviewed the cancer drug pipeline and key trends influencing development work at the pharma giant. You can watch the video, above, or stick with the script below. — JC

A star Stan­ford pro­fes­sor leaves his lab for a start­up out to re­make psy­chi­a­try

About five years ago, Amit Etkin had a breakthrough.

The Stanford neurologist, a soft-spoken demi-prodigy who became a professor while still a resident, had been obsessed for a decade with how to better define psychiatric disorders. Drugs for depression or bipolar disorder didn’t work for many patients with the conditions, and he suspected the reason was how traditional diagnoses didn’t actually get at the heart of what was going on in a patient’s brain.

Roche's Tecen­triq cross­es the fin­ish line first in ad­ju­vant lung can­cer, po­ten­tial­ly kick­ing off gold rush

While falling behind the biggest PD-(L)1 drugs in terms of sales, Roche has looked to carve out a space for its Tecentriq with a growing expertise in lung cancer. The drug will now take an early lead in the sought-after adjuvant setting — but competitors are on the way.

The FDA on Friday approved Tecentriq as an adjuvant therapy for patients with Stage II-IIIA non small cell lung cancer with PD-(L)1 scores greater than or equal to 1, making it the first drug of its kind approved in an early setting that covers around 40% of all NSCLC patients.

Imfinzi/treme­li­mum­ab com­bo scores As­traZeneca an­oth­er OS win — this time in liv­er can­cer

Is the tide turning on AstraZeneca’s battered PD-L1/CTLA4 combo?

A single priming dose of the experimental tremelimumab, followed by Imfinzi every four weeks, beat Nexavar (sorafenib) in helping a group of liver cancer patients live longer in a Phase III study, the company reported, meeting the primary endpoint.

Specifically, the two drugs extended overall survival for patients with unresectable hepatocellular carcinoma who had not received prior systemic therapy and were not eligible for localized treatment.

FDA ad­comm votes unan­i­mous­ly in sup­port of a J&J Covid-19 boost­er two months af­ter one-dose shot

The FDA’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Friday voted 19-0 in favor of authorizing a second shot of J&J’s Covid-19 vaccine to follow at least two months after the initial dose.

Regulators don’t have to follow VRBPAC’s recommendation, but they almost always do. Considering that the CDC’s advisory committee has already been set to review the expanded EUA, VRBPAC’s recommendation is likely to be adopted.

FDA+ roundup: Marks on Wood­cock­'s tenure as act­ing com­mis­sion­er; FDA lead­ers of­fer per­spec­tive on bar­ri­ers to di­ver­si­ty in re­search

CBER director Peter Marks praised Janet Woodcock’s work as acting FDA commissioner, and while noting that Biden needs to nominate someone to fill the role permanently by Nov. 16, he said he has “no idea” when that actually might occur.

“Dr. Woodcock has been at the agency for over three decades and she, during that time, has proven herself to be a remarkably capable manager,” Marks said at the Alliance for Regenerative Medicine’s meeting Tuesday. “And she’s been managing as if she’s commissioner, unlike some previous acting [commissioners] who are afraid to actually do things. She doesn’t appear to be afraid to do things. I have not felt any different now from when we had a commissioner in place,” he added.
