HBV functional cure likely to be triple combo, but no clear backbone; capsid target too crowded with other approaches showing potential, experts say
A hepatitis B virus (HBV) functional cure will likely be a triple therapy combination for most patients, but it is unclear which of the current investigated therapies are likely to have a pivotal backbone role, experts said.
Alexion’s Soliris for neuromyelitis optica treads fine line for Phase III safety; common side effects of low concern, experts say
Alexion Pharmaceuticals' (NASDAQ:ALXN) Soliris (eculizumab) is under close scrutiny for meningococcal infection risk in its Phase III for neuromyelitis optica (NMO), experts said. Even a low incidence of meningococcal infection is going to impact its risk profile, they said, though noted other adverse events (AEs) seem acceptable.
Jounce’s JTX-2011 has promising mechanism but experts highlight earliness of evidence to back clinical efficacy; combination elicits higher efficacy potential
Jounce Therapeutics’ (NASDAQ:JNCE) JTX-2011 mechanism as an inducible T-cell co-stimulator (ICOS) agonist holds promise to spur immune responses in gastric and breast cancer, experts said. However, the absence of validated clinical data draws pause on forecasting Phase I/II trial success, they noted.
Genkyotex’s Phase II GKT831 trial has sound mechanism rationale though not specific to PBC; GGT primary endpoint lacks clinical relevance, experts say
Genkyotex’s (EPA:GKTX) Phase II trial investigating GKT831 for primary biliary cholangitis (PBC) has a positive mechanism rationale for efficacy as its antioxidant and anti-inflammatory effect may have an impact on fibrosis, experts said. However, this comes with the caveat that its targets NOX1/NOX4 are not directly linked to the disease, drawing some expert caution.
J&J, Pfizer biosimilar payer policy case could survive motion to dismiss but proving anticompetitiveness remains challenging, experts say
Pfizer’s (NYSE:PFE) biosimilar antitrust claim against Johnson & Johnson (NYSE:JNJ) could be strong enough to reach the discovery stage of litigation but will survive only if the latter company's exclusionary tactics for Remicade (infliximab), beyond just lowered prices and bundling deals, are proven, said experts.
Audentes Therapeutics’ AT132 Phase I/II ASPIRO trial in XLMTM will continue with low dose for next drug treatment cohort based on safety, efficacy signals, source says
Audentes Therapeutics (NASDAQ:BOLD) does not plan to increase the dose for its next drug treatment cohort in its Phase I/II ASPIRO trial of gene therapy AT132 against X-linked myotubular myopathy (XLMTM) despite the company saying otherwise, said a source familiar. Rather, due in part to a potentially worrisome safety signal, the company intends to keep dosing patients at the same level as announced in recent data, the source said.
Blueprint’s BLU-285 mastocytosis ASH data promising, but KIT mutation-targeting knife may cut both ways – experts
Blueprint Medicines' (NASDAQ:BPMC) Phase I data for avapritinib in advanced systemic mastocytosis (SM) is praiseworthy but its advantageous target specificity could also engender resistance mutations down the line, experts said on the sidelines of the 2017 ASH meeting.
While the drug is seen as competitive to Novartis’ (VTX:NOVN) approved Rydapt (midostaurin), avapritinib’s greater specificity to KIT mutations – the driver mutation in SM – could also be a disadvantage with the resistance mutations having the potential to render the drug ineffective, experts said.
Unum plans additional cohort after cytokine release syndrome, neurotoxicity reports in Phase I lymphoma cell therapy study – source
Cytokine release syndrome (CRS) and neurotoxicity incidents have prompted Unum Therapeutics to evaluate a new dosing cohort in its Phase I study of cell therapy ACTR087 in relapsed/refractory non-Hodgkin’s lymphoma, said a source briefed on the situation.
Seres’ SER-287 elicits overall uncertainty for microbiome change for ulcerative colitis, maintenance use a possible prospect but with caveats – experts
Seres Therapeutics’ (NASDAQ:MCRB) Phase Ib SER-287 has drawn overall skeptical reviews from experts about its potential to change the microbiome of mild-to-moderate ulcerative colitis (UC) patients for clinical benefit. But any signal of microbial change in the trial’s patients would be welcome to help confirm SER-287 mechanism, they added.
Roche’s (VTX:ROG) Ocrevus (ocrelizumab) having additional reported cases of progressive multifocal leukoencephalopathy (PML) has not raised neurologist alarms despite analyst concern. Most physicians, familiar with treating PML, said the events should not negatively affect the medication’s uptake in multiple sclerosis (MS), despite contrary market opinions.
