- Regulus is a retail heavy stock which has recently tripled on mere Phase I results.
- Regulus' drug is not a one shot cure for Hep C and is inferior to Gilead's Harvoni.
- As the stock has spiked, insiders and partners have been very quick to dump large amounts of stock.
- Wednesday Regulus Therapeutics announced that it has demonstrated human proof of concept with a microRNA therapeutic from an ongoing clinical study involving the drug's use for treatment of Hepatitis C.
- Targeting microRNA for the treatment of Hep C has been attempted in the past and showed some significance, but also showed some health risks.
- It is important to understand that the drug is in very early stages, and has the potential to cause side effects according to previous studies on blocking miR-122.
- The suppression of miR-122 has a serious risk of Liver Cancer, and potential other serious side effects.
- The stock is up over 100% and I believe that is a gross overreaction.

- At The Liver Meeting in Boston, Gilead Sciences (GILD +1.1%) presented results from several Phase 2 and Phase 3 trials evaluating Harvoni (ledipasvir 90 mg/sofosbuvir 400 mg) for the treatment of chronic HCV infection in patients with limited or no treatment options, including decompensated cirrhosis, HCV recurrence following liver transplantation and patients refractory to other direct-acting antivirals.
- In a pooled analysis of Phase 2 and Phase 3 open-label studies involving more than 500 HCV-1 patients with compensated cirrhosis who received Harvoni alone or with ribavirin (RBV) for 12 or 24 weeks, 96% achieved SVR12.
- In a Phase 2 open-label study evaluating patients with decompensated cirrhosis and those with HCV recurrence after a liver transplant, 87% of those receiving Harvoni + RBV for 12 weeks achieved SVR12 compared to 89% of the treatment arm receiving a 24-week regimen (subgroup analysis of 108 HCV genotype 1 and 4 patients).
- In another subgroup analysis from the same Phase 2 trial, response rates for patients who developed HCV (genotypes 1 and 4) recurrence following liver transplantation who were treated with Harvoni + RBV were analyzed. SVR12 rates for non-cirrhotic patients were 96% and 98%, respectively, for the 12- and 24-week regimens. For patients with compensated cirrhosis, the SVR12 rate was 96% for both regimens. For patients with decompensated cirrhosis, the SVR12 rate was 81% for both regimens.
- In two studies of HCV patients who failed prior therapy, those receiving Harvoni + RBV for 12 weeks achieved SVR12 rates of 96% and 98%. Those receiving Harvoni alone for 24 weeks (Study GS-US-337-0121) achieved an SVR12 rate of 97%.

- At The Liver Meeting in Boston, Merck (NYSE:MRK) presented interim data on its triple-therapy regimen for HCV-1 infection. The investigational product combines the company's NS3/4A protease inhibitor, grazoprevir and its NS5A inhibitor, elbasvir, with Sovaldi (sofosbuvir).
- SVR4/8 for the 8-week regimen in treatment-naive cirrhotic patients was 94.7% (18 of 19). SVR4/8 values for other treatment groups, however, appear low. For the six-week regimen in treatment-naive cirrhotic patients, SVR4/8 was only 80% (16 of 20) with four relapses. For treatment-naive non-cirrhotic patients, the six-week regimen SVR4/8 was 86.7% (26/30) with four relapses while the four-week regimen failed to come anywhere close to efficacy at 38.7% (12/31) with 19 relapses.
- Of the 28 total relapses, 25 were genotype 1a and three were genotype 1b.
- The company plans to initiate Phase 2 clinical trials to assess the safety and efficacy of two short-duration triple therapy regimens: MK-3682 in combination with grazoprevir/elbasvir and MK-3682 in combination with grazoprevir and MK-8408 in non-cirrhotic HCV patients. MK-3682 is an investigational oral prodrug HCV nucleotide analogue NS5B polymerase inhibitor. MK-8408 is an investigational early-stage NS5A inhibitor.

- At this week's Annual Meeting for the Study of Liver Diseases in Boston, Achillion Pharmaceuticals (NASDAQ:ACHN) gave poster presentations on two of its HCV product candidates.
- In a Phase 2 pilot study evaluating eight-week treatment of its NS5A inhibitor, ACH-3102, in combination with Sovaldi (sofosbuvir) in treatment-naive HCV genotype 1 patients, the interferon-free, ribavirin-free regimen demonstrated 100% SVR12 in 12 patients. SVR12 or sustained viral response 12 weeks after the completion of therapy, is considered cured. Sovaldi's SVR12 (in combination with peg-interferon alfa and ribavirin) is 90% for HCV-1. Harvoni's (sofosbuvir + ledipasvir) is 94 - 99%.
- The company presented three posters on preclinical results for its uridine analog prodrug, ACH-3422. The data showed improved potency against HCV-3 compared to sofosbuvir. The combination of ACH-3422 with ACH-3102 or sovaprevir (Achillion's Phase 2 NS3/4A inhibitor) displayed additive synergistic activity in vitro. Also, ACH-3422, in combination with other direct-acting antiviral agents, demonstrated the ability to block the appearance of resistant colonies in vitro.
- According to recent research, the global prevalence of HCV genotypes is: type 1: 46%; type 2: 13%; type 3: 22% and type 4: 13%.

- Thinly-traded micro cap Regulus Therapeutics (NASDAQ:RGLS) is up a whopping 127% premarket on robust volume in response to its announcement that its experimental microRNA therapeutic, RG-101, demonstrated a mean 4 log reduction in viral load in 14 HCV patients after a single subcutaneous dose of 2 mg/kg as a monotherapy.
- Treatment with RG-101 resulted in significant and sustained reductions in HCV RNA in a variety of patients, including difficult-to-treat genotypes and some who experienced viral relapse after a prior IFN-containing regimen.
- Six of 14 patients had HCV RNA levels below the limit of quantification at day 29 and three reached day 57 below the limit.
- The study protocol has been amended to follow patients for up to six months after dosing to evaluate the possibility for certain patients to achieve viral cure after a single dose of RG-101.
- A full regimen of Gilead's (NASDAQ:GILD) HCV drug Sovaldi (sofosbuvir) involves taking a once-daily pill for almost three months.
