Eye­ing RNAi po­ten­tial in can­cer and fi­bro­sis, trans-Pa­cif­ic biotech Sir­naomics lines up $47M Se­ries C

With sup­port from a syn­di­cate that speaks to its ex­ten­sive Chi­na ties, Gaithers­burg, MD-based Sir­naomics has raised an ad­di­tion­al $22 mil­lion to close out its C round.

As its name sug­gests, the biotech is fo­cused on all things re­lat­ed to small in­ter­fer­ing RNA (siR­NA), the key mol­e­cule mR­NA si­lenc­ing. Pop­u­lar­ized by Al­ny­lam, which scored the field’s first FDA ap­proval, siR­NA kicks off ac­tion in the RNA-in­duced si­lenc­ing com­plex, which then goes on to cleave a spe­cif­ic mR­NA, there­by down­reg­u­lat­ing tar­get genes.

Sir­naomics’ big idea is to em­ploy a bet­ter ve­hi­cle to car­ry the siR­NA car­go to cells: a polypep­tide nano-par­ti­cle, or PNP, com­posed of a branched his­ti­dine ly­sine poly­mer. Ac­cord­ing to the com­pa­ny, the pep­tide is biodegrad­able, of­fers pro­tec­tion to the siR­NA while in the blood­stream, and can car­ry mul­ti­ple siR­NA se­quences, al­low­ing their prod­ucts to go af­ter mul­ti­ple genes at once. The last prop­er­ty, it em­pha­sizes, is es­pe­cial­ly cru­cial for tar­get­ing can­cer.

CR-CP Life Sci­ences Fund — a joint ven­ture of two con­glom­er­ates from Hong Kong and Thai­land re­spec­tive­ly — led the Se­ries C2. Rich Yield Cap­i­tal, Rolling Boul­der In­vest­ment and Leg­end Sky In­vest­ment all chipped in to bring Sir­naomics over the $47 mil­lion line in to­tal.

The pro­ceeds will help pro­pel the lead drug can­di­date, STP705, for­ward, in­clud­ing an on­go­ing Phase II for non-melanoma skin can­cer and an­oth­er in bile duct can­cer/liv­er can­cer slat­ed to be­gin lat­er this year. There’s al­so a Phase II tri­al for hy­per­trophic scar re­duc­tion in Chi­na as Sir­naomics’ ex­plores the lead drug’s po­ten­tial in fi­brot­ic dis­eases.

“Sir­naomics is the on­ly biotech­nol­o­gy com­pa­ny con­duct­ing clin­i­cal drug de­vel­op­ment in the field of RNAi ther­a­peu­tics both in USA and Chi­na, the two ma­jor mar­kets for on­col­o­gy and fi­bro­sis,” Da Liu, the man­ag­ing di­rec­tor of CR-CP Life Sci­ence Fund, said in a state­ment.

Liu added that the biotech has a “tru­ly in­ter­na­tion­al” man­age­ment team, with a siz­able C-suite com­pris­ing CEO Patrick Lu, CMO Michael Molyneaux, CSO David Evans, COO George Ji, chief tech­ni­cal of­fi­cer Dmit­ry Samarsky, and chief pro­duc­tion of­fi­cer Marc Lemaître.

AveX­is sci­en­tif­ic founder fires back at No­var­tis CEO Vas Narasimhan, 'cat­e­gor­i­cal­ly de­nies any wrong­do­ing'

Brian Kaspar’s head was among the first to roll at Novartis after company execs became aware of the fact that manipulated data had been included in its application for Zolgensma, now the world’s most expensive therapy.

But in his first public response, the scientific founder at AveXis — acquired by Novartis for $8.7 billion — is firing back. And he says that not only was he not involved in any wrongdoing, he’s ready to defend his name as needed.

I reached out to Brian Kaspar after Novartis put out word that he and his brother Allen had been axed in mid-May, two months after the company became aware of the allegations related to manipulated data. His response came back through his attorneys.

We­bi­nar: Re­al World End­points — the brave new world com­ing in build­ing fran­chise ther­a­pies

Several biopharma companies have been working on expanding drug labels through the use of real world endpoints, combing through the data to find evidence of a drug’s efficacy for particular indications. But we’ve just begun. Real World Evidence is becoming an important part of every clinical development plan, in the soup-through-nuts approach used in building franchises.

I’ve recruited a panel of 3 top experts in the field — the first in a series of premium webinars — to look at the practical realities governing what can be done today, and where this is headed over the next few years, at the prodding of the FDA.

As­traZeneca’s Imfinzi/treme com­bo strikes out — again — in lung can­cer. Is it time for last rites?

AstraZeneca bet big on the future of their PD-L1 Imfinzi combined with the experimental CTLA-4 drug tremelimumab. But once again it’s gone down to defeat in a major Phase III study — while adding damage to the theory involving targeting cancer with a high tumor mutational burden.

Early Wednesday the pharma giant announced that their NEPTUNE study had failed, with the combination unable to beat standard chemo at overall survival in high TMB cases of advanced non-small cell lung cancer. We won’t get hard data until later in the year, but the drumbeat of failures will call into question what — if any — future this combination can have left.

UP­DAT­ED: Pay­back? An­a­lysts say Sarep­ta was blind­sided by an FDA re­jec­tion dri­ven by reg­u­la­to­ry re­venge

In one of the least anticipated moves of the year, the FDA has rejected Sarepta’s application for an accelerated approval of its Duchenne MD drug golodirsen after fretting over safety issues.

In a statement that arrived after the bell on Monday, Sarepta explained the CRL, saying:

Af­ter a posse of Wall Street an­a­lysts pre­dict a like­ly new win for Sarep­ta, we're down to the wire on a crit­i­cal FDA de­ci­sion

As Bloomberg notes, most of the Wall Street analysts that cover Sarepta $SRPT are an upbeat bunch, ready to cheer on the team when it comes to their Duchenne MD drugs, or offer explanations when an odd setback occurs — as happened recently with a safety signal that was ‘erroneously’ reported last week.

FDA de­ci­sion on Ver­tex's CF triple will come just ahead of planned CEO shake­up

Vertex has clinched a priority review for the all-important cystic fibrosis triple that will blaze the trail for treating a large group of patients unhelped by its current drugs.

FDA regulators have set a PDUFA date of March 19, 2020, just a year after the Boston biotech posted positive Phase III results showing that people with two F508del mutations experienced statistically significant improvements in lung function after a 4-week regimen of VX-445, tezacaftor and ivacaftor. After reviewing 24-week data among patients with one F508del mutation and one minimal function mutation — and thoroughly comparing the VX-445 triple with another combo featuring VX-659 on scores like safety, drug-drug interactions, and photosensitivity — Vertex ultimately went with VX-445.

An MIT spin­out kills one of its ‘liv­ing ther­a­peu­tics’ af­ter flunk­ing an ear­ly-stage study — shares rout­ed

Just a few weeks after bagging $80 million in a deal to collaborate with Gingko Bioworks on its special blend of engineered bacteria used for “living therapeutics,” little Synlogic in Boston $SYBX is tossing one of its two clinical programs after watching an early-stage study go down in defeat.

Their Phase Ib/IIa study for SYNB1020 to counter the accumulation of ammonia in the body, a condition called hyperammonemia or urea cycle disorder, floundered at the interim readout, forcing the biotech to kill it and reserve its cash for pipeline therapies with greater potential.

Elan­co to buy Bay­er's an­i­mal health busi­ness for $7.6B, as deal­mak­ing gath­ers steam in the sec­tor

Last week, Elanco explicitly dodged answering questions about its rumored interest in Bayer’s animal health business in its post-earnings call. On Tuesday, the Eli Lilly spinoff disclosed it was purchasing the German drug maker’s veterinary unit in a cash-and-stock deal worth $7.6 billion. 

Elanco $ELAN has been busy on the deal-making front. In April, it laid out plans to swallow its partner, Kansas-based pet therapeutics company Aratana $PETX. A July report by Reuters suggested a potential Bayer deal was being explored, and Bloomberg last week said the deal was imminent, citing sources.
