Strug­gling Heat gets a warm re­sponse to a snap­shot on can­cer vax da­ta

Jeff Hutchins, Heat Bi­o­log­ics

Heat Bi­o­log­ics man­aged to at least tem­porar­i­ly ex­tri­cate it­self from pen­ny stock ter­ri­to­ry af­ter of­fer­ing a pos­i­tive up­date on its com­bi­na­tion study for non-small cell lung can­cer. Its stock surged more than 20% this morn­ing based on an up­date for a hand­ful of pa­tients tak­ing a com­bi­na­tion of HS-110 and Bris­tol-My­ers Squibb’s check­point in­hibitor Op­di­vo.

The up­dat­ed snap­shot from the Durham, NC-based biotech in­clud­ed a note that 3 of 5 pa­tients en­rolled in a co­hort for low tu­mor in­fil­trat­ing lym­pho­cytes “ex­pe­ri­enced sig­nif­i­cant tu­mor re­duc­tion, which is high­er than the 10% re­sponse rate of low TIL pa­tients re­port­ed for ex­ist­ing da­ta on nivolum­ab alone.” 5 of 12 evalu­able pa­tients ex­pe­ri­enced an im­mune re­sponse to the com­bo.

As a re­sult Heat’s stock $HBTX nosed above the $1 mark.

Heat has ex­pe­ri­enced re­peat­ed set­backs that ground down its share price.  Last spring, the biotech cut staff. Then in the fall their drug HS-410 failed a mid-stage study for blad­der can­cer. The com­pa­ny cur­rent­ly has a mi­cro mar­ket cap hov­er­ing around $24 mil­lion, putting it in a very vul­ner­a­ble group. And Nas­daq is­sued a delist­ing warn­ing just a few days ago.

“Check­point in­hibitors, such as nivolum­ab, are cur­rent­ly ef­fec­tive in treat­ing ap­prox­i­mate­ly 10% of lung can­cer pa­tients with low TIL and about 20% of pa­tients over­all in the 2nd line set­ting,” said Jeff Hutchins, Heat’s top sci­en­tist and SVP, Pre­clin­i­cal De­vel­op­ment. “Our re­sults ap­pear to fur­ther val­i­date the ex­pect­ed mech­a­nism of ac­tion of our ap­proach in com­bi­na­tion with check­point in­hibitors, with a con­tin­u­ing trend to­wards ear­ly and sus­tained T cell ac­ti­va­tion in the pe­riph­er­al blood cells.”

What Will it Take to Re­al­ize the Promise and Po­ten­tial of Im­mune Cell Ther­a­pies?

What does it take to get to the finish line with a new cancer therapy – fast? With approvals in place and hundreds of immune cell therapy candidates in the pipeline, the global industry is poised to create a fundamental shift in cancer treatments towards precision medicine. At the same time, unique challenges associated with cell and process complexity present manufacturing bottlenecks that delay speed to market and heighten cost of goods sold (COGS) — these hurdles must be overcome to make precision treatments an option for every cancer patient. This series of articles highlights some of the key manufacturing challenges associated with the production of cell-based cancer therapies as well as the solutions needed to transcend them. Automation, process knowledge, scalability, and assured supply of high-quality starting material and reagents are all critical to realizing the full potential of CAR-based therapies and sustaining the momentum achieved in recent years. The articles will highlight leading-edge technologies that incorporate these features to integrate across workflows, accelerate timelines and reduce COGS – along with how these approaches are enabling the biopharmaceutical industry to cross the finish line faster with new treatment options for patients in need.

The biggest ques­tions fac­ing gene ther­a­py, the XLMTM com­mu­ni­ty, and Astel­las af­ter fourth pa­tient death

After three patients died last year in an Astellas gene therapy trial, the company halted the study and began figuring out how to safely get the program back on track. They would, executives eventually explained, cut the dose by more than half and institute a battery of other measures to try to prevent the same thing from happening again.

Then tragically, Astellas announced this week that the first patient to receive the new regimen had died, just weeks after administration.

EQRx, CStone un­furl full lung can­cer da­ta for PD-L1 drug in what the part­ners are call­ing a first

As a self-stylized drug pricing disruptor, EQRx has high hopes for its lead PD-(L)1 to offer proof of concept for the entire business model. After touting a win back in May, the biotech is back with full data in lung cancer that could back up an approval.

Patients dosed with EQRx and CStone Pharmaceuticals’ sugemalimab posted median progression-free survival of 9 months compared with 5.8 months for patients given placebo (p=0.0026), according to full data from the Phase III GEMSTONE-301 study in Stage III non-small cell lung cancer set to be presented at this weekend’s #ESMO21.

Am­gen rolls out da­ta for KRAS in­hibitor com­bo study in col­orec­tal can­cer, hop­ing to move on from ug­ly ear­ly re­sults

With the first win for its KRAS inhibitor sotorasib in hand, Amgen is pushing ahead with an aggressive clinical plan to capitalize on its first-to-market standing. The drugmaker thinks combinations — in-house or otherwise — could offer a path forward, and one early readout from that strategy is bearing fruit.

A combination of Amgen’s sotorasib and its EGFR inhibitor Vectibix posted an overall response rate of 27% in 26 patients with advanced colorectal cancer (CRC) with the KRAS-G12C mutation, according to data from the larger Phase Ib/II CODEBREAK 101 study set to present at this weekend’s virtual ESMO Congress.

As­traZeneca touts Imfinzi im­munother­a­py com­bos for lung can­cer in push to dri­ve PD-L1 drug up­take

Facing the big dogs in the PD-(L)1 space, AstraZeneca has taken its own contender Imfinzi into blockbuster territory in its four years on the market but sees even bigger things for the drug. Combinations could be the key, and early results from a mid-stage test are adding some fuel to that strategy.

Imfinzi combined with one of two investigational immunotherapies — a CD73 antibody dubbed oleclumab or an Innate’s anti-NGK2a named monalizumab — topped Imfinzi alone in terms of overall response and progression-free survival in patients with stage III non-small cell lung cancer whose tumors had not worsened during concurrent chemoradiation, according to interim data from the Phase II COAST trial set to be presented at #ESMO21.

Gri­fols drops $1B on Ger­man hold­ing com­pa­ny in con­tin­ued plas­ma push

One Spanish biotech is beefing up its plasma therapy operations, and on Friday, it announced that it’s doing so in a billion-dollar deal.

Grifols is now the largest shareholder of Biotest, a company valued at more than $1.8 billion. By teaming up, the two will try to increase the number of plasma therapies available and increase patient access around the world, Grifols said in a press release.

The company did so by acquiring holding company Tiancheng Pharmaceutical, the Germany-based owner of nearly 90% of Biotest shares, for nearly $1.27 billion. Grifols now owns nearly 90% of Biotest voting rights and almost 45% of the total share capital of Biotest.

Eu­ro­pean study finds that Gilead­'s Covid-19 an­tivi­ral remde­sivir shows no clin­i­cal ben­e­fit

Gilead’s remdesivir — or Veklury, as it’s marketed in the US — raked in around $2.8 billion last year as the only FDA-approved antiviral to treat Covid-19. But new data from a European study suggest the drug, which has been given to about half of hospitalized Covid patients in the country, has no actual benefit.

The open-label DisCoVeRy trial enrolled Covid-19 patients across 48 sites in Europe to test a handful of treatments, including remdesivir, lopinavir–ritonavir, lopinavir–ritonavir and interferon beta-1a, and hydroxychloroquine. To participate, patients had to show symptoms for seven days and require oxygen support. A total of 429 patients were randomized to receive remdesivir plus standard of care, while 428 were assigned to standard of care alone.

Zymeworks squares up with Her­ceptin af­ter HER2 bis­pe­cif­ic aces mid-stage test in esophageal can­cer

Roche’s Herceptin has long stood as standard of care across multiple advanced cancers, but a suite of next-gen players are looking to beat the aging giant at its own game. In HER2-expressing esophageal cancer, BeiGene partner Zymeworks thinks its bispecific antibody could have the juice to get it done.

Zymeworks’ bispecific antibody zanidatamab, combined with one of two chemotherapy regimens, posted an overall response rate of 75% in patients with advanced gastroesophageal adenocarcinoma (GEA) who had not previously received a HER2-targeted cancer therapy, the Vancouver-based biotech said Thursday.

Covid-19 roundup: FDA re­veals boost­er ad­comm ques­tion; Eli Lil­ly's an­ti­body cock­tail cleared for pre­ven­tion

The FDA released briefing documents this week from the agency and Pfizer each outlining their arguments for today’s Covid-19 booster shot adcomm, but one thing conspicuously missing was the question on which panel members would be voting. But late Thursday night, regulators published that question.

Adcomm members will be asked whether or not the safety and efficacy data from Pfizer/BioNTech’s original Phase III study “support approval” of a booster shot at least six months after the second dose in individuals older than 16. The question notably excludes the real-world data from Israel and other analyses that Pfizer and the Biden administration had said would be a centerpiece of their arguments for boosters.
