    BioBoyScout over ARO-COV.:

    Sharing a thought on Arrowhead's COVID drugs that are under development, and I would love to get your thoughts on what you think. My guess is that Arrowhead may be finalizing somewhere between 1-3 drugs to tackle all variants of the virus. As you may know, being able to effectively target other variants is now a very big concern, as these new variants are starting to cause problems (both in the ability to spread and how deadly they are). Health departments everywhere are now testing approximately 10% of all nasal swabs for the variants, and if they're found, they tend to hone in on that patient extra hard to try and stop the spread (good luck with that effort, given how fast this virus spreads).

    With that said, I can't imagine that Arrowhead would advance any of their COVID drugs all the way though the clinic without partnering, as the trials will need to be large and will require the attention that only a BP can give. Arrowhead can probably do a phase 1/2 on their own, however, this is probably worthless given the gravity and the need for these drugs. Additionally, phase 1 will probably need to be fairly complex in order to effectively target all the various different populations and to advance it broadly in the trials. I think it would probably be wisest to partner on day 1, as BP would know best on exactly the right populations to target - something that I believe is beyond Arrowhead's expertise.

    Therefore, I surmise that if and when Arrowhead introduces its COVID drugs, it will probably be with a BP partner. I don't think this is any easy task to convince a BP to invest around a half-billion or more of its money on testing an RNAi approach, especially since there are now many vaccines hitting the market with efforts to add boosters to cover other variants. In any event, time is ticking, which is why a suspect that we may hear something within the next month or two on their COVID drugs.

    ARC 520 resultaten zijn op 12 maart 2021 online gezet:

    Abstract
    Objective We examined the serological, virological (in serum and liver) and histological profiles in chronic hepatitis B virus (HBV) patients during and after completion of multiple dose (MD) ARC-520.

    Design The present phase 1b study was a multidose, open-label extension cohort of patients that had received single dose ARC-520 in our previous study. Eight patients received 4–9 4 weekly doses of MD ARC-520 and entecavir. Liver biopsies were performed in six patients. Intrahepatic and serum HBV DNA, HBV RNA and viral antigens were measured.

    Results All patients had 28.9–30.4 months of follow-up after the last MD. All three hepatitis B e antigen (HBeAg)-positive patients had profound reductions in hepatitis B surface antigen (HBsAg), HBeAg, hepatitis B core-related antigen and HBV RNA with two undergoing HBeAg seroconversion. One further achieved HBsAg seroconversion (anti-HBs level of 25.1 IU/L) and the remaining two had HBsAg reductions of -1.7 and -3.5 log IU/mL >30 months after MD. Among the five HBeAg-negative patients, four had modest HBsAg reduction >29 months after completion of MD and one achieved HBsAg seroconversion (anti-HBs level of 152.5 IU/L) and was negative for liver HBsAg staining. Entecavir was successfully stopped in this patient 12 months after HBsAg seroconversion. Temporally related alanine aminotransferase elevations preceded by HBsAg reductions were observed in three patients suggesting immune activation. HBcAg staining was negative in all six biopsied patients. Two patients with <10% HBsAg positive staining of hepatocytes had correspondingly low serum HBsAg levels of 1.5 and 11.5 IU/mL.

    Conclusions MD ARC-520 therapy achieved sustained and profound reductions of viral antigens and HBV RNA. HBsAg seroclearance was achievable.

    Op slide #12 staat het: 39% sustained responders (=fc?) bij hepatitis b door gebruik van JNJ/ARWR rnai technologie. Op het Yahoo forum wordt druk gespeculeerd of de combi's die JNJ toepast nog betere scores opleveren. Er is gerede hoop op:

    Dit zal tzt toch een uitslaande brand moeten veroorzaken lijkt me.

    Welkom, het moet allemaal nog beginnen... :-)
    Huidige dip lijkt me ook een mooi instappunt. HepB lijkt ook tekening in te komen: the JNJ combi was well tolerared (slide 15)! Ook hier scoort rnai beter dan aso (volgens eerder genoemde presentatie vandaag). Ik verheug me inmiddels ook op cf en nierkanker trial uitkomsten in Q2.

    Nog meer data. Vreselijk ingewikkelde ziekte.

    39% sustained responders. Dat lijken me toch prima resultaten. Waarom dit publiek maken middels een persbericht? Nu wordt er weinig tot geen aandacht aan geschonken. Of is het wachten op de combo resultaten?
