Gen­Sight has a gene ther­a­py mys­tery on its hands, which is about the last thing it want­ed at the end of Phase III.

As­sess­ing the 48-week da­ta from its first piv­otal test of a treat­ment for Leber Hered­i­tary Op­tic Neu­ropa­thy — or LHON, a rare ge­net­ic dis­ease that caus­es blind­ness — in­ves­ti­ga­tors pulled out a mean­ing­ful im­prove­ment in sight in their one treat­ed eye.

The mys­tery: The oth­er eyes that re­ceived a sham ther­a­py did just as well with their eye­sight. Ex­act­ly as well.

That makes the Phase III study of GS010 a fail­ure, and rather than stay to try and solve the mys­tery, in­vestors bailed, dri­ving down the Eu­roNext stock $SIGHT down by 34%.

One of the rea­sons why the ear­ly gene ther­a­py pi­o­neers like Gen­Sight picked hered­i­tary eye dis­eases to go af­ter first is that the eye is a con­tained unit, lim­it­ing off-tar­get ef­fects. But Gen­Sight’s Paris-based CEO Bernard Gilly says that as on­ly a frac­tion of pa­tients his­tor­i­cal­ly see a spon­ta­neous im­prove­ment in eye­sight, he’s won­der­ing if the ther­a­py in­ject­ed in­to one eye de­liv­ers an un­ex­pect­ed ben­e­fit to the oth­er.

At the same time, Gen­Sight tout­ed a hit on a reti­nal bio­mark­er for the dis­ease, which they claimed as ev­i­dence that the ther­a­py had an im­pact sep­a­rate from the sham.

“The fact that struc­tur­al mea­sures of the reti­na showed such a large sta­tis­ti­cal dif­fer­ence with treat­ment is com­pelling and ob­jec­tive ev­i­dence that this gene ther­a­py pro­tects the in­tegri­ty of many reti­nal gan­glion cells from the dam­age of LHON,” com­ment­ed com­pa­ny co-founder José-Alain Sa­hel.

That’s a messy ar­gu­ment, with the com­pa­ny ar­gu­ing that it ap­peared the ther­a­py im­proved sight for both eyes, but on­ly hit the sec­ondary bio­mark­er in the treat­ed eye. 

The com­pa­ny — which tried and failed to make it on­to Nas­daq — will be left look­ing for more da­ta to an­a­lyze from its next two Phase III stud­ies, which are up­com­ing. But easy ex­pla­na­tions will be hard to come by.

Novartis $NVS may have given up, but Amgen $AMGN and Allergan $AGN are plowing ahead with their knockoff of Roche’s blockbuster biologic Rituxan in the United States.

Their copycat, ABP 798, was found to have a clinically equivalent impact as Rituxan — meeting the main goal of the study involving CD20-positive B-cell non-Hodgkin’s lymphoma patients. This is the second trial supporting the profile of the biosimilar. In January, it came through with positive PK results in patients with rheumatoid arthritis.

→ BeiGene $BGNE is getting a boost in its drive to field a rival to Imbruvica. The FDA has offered an accelerated review to zanubrutinib, a BTK inhibitor that has posted positive results for mantle cell lymphoma. The PDUFA date lands on February 27, 2020. The drug scored breakthrough status at the beginning of the year.

→ BeiGene isn’t the only biopharma company to gain special regulatory status today. Mustang Bio $MBIO and St. Jude Children’s Research Hospital announced that MB-107, a lentiviral gene therapy for the treatment of X-linked severe combined immunodeficiency, also known as bubble boy disease, has been granted Regenerative Medicine Advanced Therapy status.

The Trump administration is not giving up just yet. On Wednesday, the HHS filed an appeal against a judge’s decision in July to overturn a ruling obligating drug manufacturers to disclose the list price of their therapies in television adverts — hours before it was stipulated to go into effect.

In May, the HHS published a final ruling requiring drugmakers to divulge the wholesale acquisition cost— of a 30-day supply of the drug — in tv ads in a bid to enhance price transparency in the United States. The pharmaceutical industry has vehemently opposed the rule, asserting that list prices are not what a typical patient in the United States pays for treatment — that number is typically determined by the type of (or lack thereof) insurance coverage, deductibles and out-of-pocket costs. Although there is truth to that claim, the move was considered symbolic in the Trump administration’s healthcare agenda to hold drugmakers accountable in a climate where skyrocketing drug prices have incensed Americans on both sides of the aisle.

Versant is once again stepping off the beaten track in biotech to see if they can blaze a trail of their own in a field that has looked too thorny to many investors for years.

The venture group and their partners at Apple Tree are bringing their latest creation out of stealth mode today. Born in Versant’s Inception Sciences’ Chinook Therapeutics is betting that its preclinical take on kidney disease can get an early lead among the companies starting up in the field.

Using a laptop borrowed from his former employer, South London’s St George’s Hospital, Sir Andrew Dillon set about establishing NICE — launched by the then health secretary Frank Dobson — in 1999.  On Thursday, the UK cost-effectiveness watchdog said its first and only chief executive — Dillon — is stepping down in March 2020.

Back in the day, decisions about which drugs and interventions were funded by the National Health Service (NHS) were made at the local level, but this ‘postcode prescribing’ system was fraught with skewed healthcare deployment making the structure unsustainable. A national system was deemed necessary — and NICE was formed to bridge that gap.
