Boehringer Ingelheim today announced new data from its Phase III clinical trial programme, STARTVerso™, which evaluates faldaprevir* in combination with pegylated interferon and ribavirin (PegIFN/RBV). Patients with genotype-1 (GT-1) hepatitis C (HCV) who have not received previous treatment (treatment-naïve: STARTVerso™1&2),1 treatment-experienced patients (STARTVerso™3),2 and HIV co-infected patients (STARTVerso™4)3 participated in this study programme. The results from these and additional studies will be presented at the 64th Annual Meeting of the American Association for the Study of Liver Diseases (AASLD), also known as The Liver Meeting®, taking place 1-5 November in Washington, D.C.
Faldaprevir (formerly BI 201335) is an experimental drug candidate for the treatment of hepatitis C. It is being developed byBoehringer-Ingelheim and is currently in Phase III trials.[1]
Faldaprevir is a hepatitis C virus protease inhibitor.
Faldaprevir is being tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including BI 207127.
Data from the SOUND-C2 study, presented at the 2012 AASLD Liver Meeting, showed that a triple combination of faldaprevir, BI 207127, and ribavirin performed well in HCV genotype 1b patients.[2] Efficacy fell below 50%, however, for dual regimens without ribavirin and for genotype 1a patients.

Synthesis and optimization of a novel series of HCV NS3 protease inhibitors: 4-Arylproline analogs
The following Compound 1):
(1)
wherein B is
; L° is MeO-; L1 is Br; and R2 is and having the chemical name: l-{ [4-[8-Bromo-2-(2-isopropylcarbamoyl-thiazol-4-yl)-7- methoxy-quinolin-4-yloxy]-l-(R)-(2-cyclopentyloxycarbonyl amino-3,3-(S)-dimethyl- butyryl)-pyrrolidine-(S)-2-carbonyl]-amino}-2-(S)-vinyl-cyclopropane-(R)-carboxylic acid, is known as a selective and potent inhibitor of the HCV NS3 serine protease and useful in the treatment of HCV infection. Compound (1) falls within the scope of the acyclic peptide series of HCV inhibitors disclosed in U.S. Patents RE 40,525, 7,514,557 and 7,585,845. Compound (1) is disclosed specifically as Compound # 1055 in U.S. Patent 7,585,845, and as Compound # 1008 in U.S. Patent 7,514,557. Compound (1), and pharmaceutical formulations thereof, can be prepared according to the general procedures found in the above-cited references, all of which are herein incorporated by reference in their entirety. Preferred forms of Compound (1) include the crystalline forms, in particular the crystalline sodium salt form, which can be prepared as described in U.S. Patent Application Publication No. 2010/0093792, also incorporated herein by reference. Data demonstrating the activity of Compound (1) as an inhibitor of the HCV NS3 serine protease and its corresponding demonstrated utility in the treatment of HCV infection in mono-infected patients, can be found in U.S. Patent 7,585,845, as well as in numerous publications presenting the preclinical characterization or clinical trial results with Compound (1). See, e.g., Sulkowski MS, et al, Hepatol (2009), Vol. 50, pg. 2A, Abtract LB3; Sulkowski MS, et al., J Hepatol (2010) Vol. 52, Supp. 1, pgs. S462-S463, Abstract 1190; Berg et al., Hepatol (2010), Vol. 52, Supp. SI, Abstract 804; and White PW, et al., Antimicrob Agents Chemother (2010) 54(11):4611-4618.
Combination therapy regimens directed to administering Compound (1) with an interferon- alpha and ribavirin for the treatment of HCV infection are described in U.S. Patent Application Publication Nos. 2010/0068182 and 2011/0268700.
HIV/HCV coinfected persons tend to have higher HCV viral loads and are less likely to clear the HCV spontaneously. The urgency for treatment of persons who are coinfected is greater than it is for those with HCV infection alone. The course of liver disease is more rapid in HIV/HCV-coinfected persons, including an approximately 2-fold increased risk of cirrhosis, more rapid progression to decompensated liver disease and increased risk for hepatocellular carcinoma (Graham CS, et al., Clin Infect Dis (2001 );33:562-569) .
Treatment of HCV might improve the tolerability of highly active antiretroviral therapy (HAART) because HCV infection increases the risk of mitochondrial toxicity and hepatotoxicity from HAART (Sulkowski MS, et al., JAMA (2000);283:74-80; Lafeuil!ade A, et al., Lancet (2001);357:280-281 ). Although there is much less published information on treatment outcomes in those who are HIV/HCV-coinfected than in HCV mono-infected patients, all accumulated data demonstrate that sustained virological response (SVR) and cure from HCV infection with pegylated interferon alpha and ribavirin is achieved in a substantially lower proportion of HIV/HCV coinfected patients when compared to HCV mono-infected patients. Factors associated with a poor treatment response (e.g., a high baseline HCV viral load, cirrhosis, and African American race) are present in a higher proportion of HIV/HCV coinfected populations, when compared to HCV monoinfected populations. It is not clear to what extent HIV infection itself diminishes the SVR rate, and to what extent advanced immunosuppression (e.g., CD4+ T lymphocyte count <200/mm3) further reduces response to HCV treatment (Toriani FJ, et al., N Engl J Med (2004);351(5): 438 -50; Nunez M, et al., ARHR (2007); 23(8):972-982).
Thus, there is a continuing high unmet need in the art for therapies that are effective against HCV in patients that are co-infected with HIV.

Technical Data
References
Yao et al (2006) Pharmacological, pharmacokinetic, and clinical properties of benidipine hydrochloride, a novel long-acting calcium channel blocker. J.Pharmacol.Sci. 100 243. PMID: 16565579.

Benidipine hydrochloride, whose chemical name is (±)-(R*)- 1 ,4-dihydro-2,6-dimethyl-4-(meta-nitrophenyl)-3 ,5-pyridinedica rbolate methyl ester [(R*)-l-benzyl-3-piperidine alcohol ester], belongs to dihydropyridine receptor antagonist. It can bind to dihydropyridine receptors at the binding site with high affinity and high specificity, and shows a strong inhibitory effect on Ca channel. Benidipine not only has an inhibitory effect on muscular (L-type) Ca channel, but also has an inhibitory effect on voltage-dependent N- and T-type Ca channels. It is, up to now, the only calcium antagonist that can inhibit all the three Ca channels mentioned above. Furthermore, benidipine has highly affinity with cell membrane, has vascular selectivity and renal protection effect. Therefore, it is an ideal, safe and effective agent for the treatment of hypertension and renal parenchymal hypertension and angina.
There are two chiral atoms in the molecule of benidipine hydrochloride, which locate on site 4 of the dihydropyridine ring and site 3′ of the side chain piperidine ring. Accordingly, benidipine hydrochloride has 4 optical isomers: (S)-(S)-(+)-a, (R)-(R)-(-)-a, (R)-(S)-(+)^ and (S)-(R)-(-)^, and the active ingredients for drug are the mixture of (S)-(S)-(+)-a and (R)-(R)-(-)-0L Therefore, it is necessary to separate a and β isomers during the post- treatment stage of benidipine hydrochloride preparation.
Based on the order of synthesis of dihydropyridine main ring, there mainly are two groups of total 5 synthesis routes of benidipine hydrochloride. Among them, there are two routes which involve synthesis of the main ring first: 1) acylchloridizing the main ring of dihydropyridine and then linking the side chain to synthesize directlybenidipine hydrochloride; 2) After acylchloridizing the main ring of dihydropyridine, 3-piperidinol and then benzyl is added. The routes involve the synthesis of the main ring later includes the following; 1) synthesizing the main ring via β-aminocrotonate; 2) synthesizing the main ring via acetylacetate ester; 3) the One-pot’ method involving 3-nitrobenzaldehyde, β-aminocrotonate and acetylaceate ester.
Several synthetic routes of benidipine hydrochloride and its analogues have been disclosed in EP0063365A1, EP0161877A2, JP57-171968A, EP0106275 A2, etc. Among them, EP0106275 A2 gave a summary of the synthetic pathways ofbenidipine hydrochloride. In all of the above references, it was mentioned to separate the benidipine hydrochloride prepared through column chromatography and spit it into its a and β isomers, thus obtain the therapeutically active (±)-a-benidipine hydrochloride.
In order to obtain a highly purified benidipine hydrochloride meeting pharmaceutical use, it is necessary to perform multiple recrystallization with acetone and/or ethanol. Moreover, the crystallization condition is relatively strict since it should be performed below freezing point or even below -20 °C . Furthermore, the crystallization process usually need a relatively long time (more than 24 hours).
JP2007-8819A thus disclosed a method for preparing highly purified benidipine hydrochloride meeting pharmaceutical use by first preparing the monohydrate of benidipine hydrochloride.
Because benidipine hydrochloride has a very low solubility, for dissolving in a solvent quickly, benidipine hydrochloride is often grounded into nanoparticles. CN 1794993 A provided a method to grind benidipine hydrochloride into particles of 1.0^50.0 μπι. The mechanical grinding method is performed by grinding larger particles of crystals into desired smaller size of crystals. This method consumes large amount of energy and time, and results in a widely distribution of the crystal particle size.
PEOPLE found the desired sizes of benidipinehydrochloride nanoparticles could be obtained by ultrasonic crystallization technology. Unlike the method of CN 1794993 A, the method according to the present invention obtains crystals from smaller to larger sizes. The distribution of particle sizes in the method of the present invention is relatively narrower since the solvent crystalizes rapidly and steadily in the solution. Overall, the present invention can save time and energy, and is readily for preparation. Summary of the invention

Solanezumab, Eli Lilly’s anti-beta-amyloid monoclonal antibody for Alzheimer’s disease
The market for Alzheimer’s disease therapies is set to nearly triple between 2012 and 2022, despite increasing genericisation and the fact that few new product launches are expected during this time, according to new forecasts.
The key driver of growth in the AD market will be Eli Lilly’s anti-beta-amyloid monoclonal antibody solanezumab, the first potentially disease-modifying therapy (DMT) to launch for AD, according to the study, from Decision Resources. It reports that solanezumab is expected to launch in the seven major pharmaceutical markets – the US, France, Germany, Italy, Spain, the UK and Japan – starting in 2018 and that, by 2022, the drug is forecast to attain sales in excess of $5 billion in these markets.
More than 85% of solanezumab’s projected total use in 2022 will be in the mild AD market – the population in which the drug is currently being tested – followed by the pre-AD 1-2 years market segment, says the firm, which defines this latter population as those patients who will go on to develop overt AD within the next one to two years.
Solanezumab (proposed INN) is a monoclonal antibody being investigated by Eli Lilly as a neuroprotector[1] for patients withAlzheimer’s disease.[2][3]
It binds to the amyloid-β peptides that make up the protein plaques seen in the brains of people with the disease.
2012 results of the EXPEDITION 1 & 2 phase 3 clinical trials were only mildly encouraging.[4][5][6] but were said to be the “first evidence that targeting the amyloid cascade can slow the progression of disease.”[7]

Mitochondria-targeting Cisplatin
Cisplatin is a chemotherapy drug given to more than half of all cancer patients. The drug kills cells very effectively by damaging nuclear DNA, but if tumors become resistant to cisplatin they often grow back.
A new study from the Massachusetts Institute of Technology (MIT) and the University of Toronto offers a possible way to overcome that resistance. The researchers found that when cisplatin was delivered to cellular structures called mitochondria, DNA in this organelle was damaged, leading to cancer cell death. Moreover, the mitochondrial-targeted drug could overcome cisplatin resistance.
“These results suggest that the mitochondria can be an important target for platinum-based drugs,” said Robert Radford, an MIT postdoc and an author of a paper describing the findings in the Oct. 31 online edition of the journal Chemistry & Biology.
Mitochondria-targeting cisplatin might also be effective at lower doses than regular cisplatin, helping to avoid…

Roche’s new leukaemia drug, Obinutuzumab, superior to Rituxan in clinical trial
JULY 25, 2013 12:52 AM / 6 COMMENTS / EDIT
July 24 2013 | By Márcio Barra
Roche has announced that its experimental leukemia drug GA101, or obinutuzumab, used in combination with chemotherapy, was better than Rituxan at helping people with chronic lymphocytic leukemia live longer without their disease worsening, according to the results from the second phase of the clinical trial. Both drugs were tested and compared in combination with chlorambucil.
Roche’s Phase III leukemia drug Obinutuzumab (GA101) yields positive results
- GA101 is the first glycoengineered, type II anti-CD20 mAb.

Obinutuzumab (GA101)
| FORMULA | C6512H10060N1712O2020S44 |
|---|
GA101 is the first glycoengineered, type II anti-CD20 monoclonal antibody (mAb) that has been designed for increased antibody-dependent cellular cytotoxicity (ADCC) and Direct CellDeath.1 This agent is being investigated in collaboration with Biogen Idec.
Swiss pharmaceutical company Roche has announced that its early Phase III trial of Leukemia drug obinutuzumab (GA101) demonstrated significantly improved progression-free survival in people with chronic lymphocytic leukemia (CLL).
The positive results yield from stage 1 of a three-arm study called CLL11, designed to investigate the efficacy and safety profile of obinutuzumab (GA101) plus chlorambucil, a chemotherapy, compared with chlorambucil alone in people with previously untreated chronic lymphocytic leukemia (CLL).
This phase of the study met its primary endpoint and an improvement in progression-free survival was achieved; obinutuzumab plus chlorambucil significantly reduced the risk of disease worsening or death compared to chlorambucil alone.
Roche chief medical officer and global product development head Hal Barron said; “the improvement in progression-free survival seen with GA101 is encouraging for people with CLL, a chronic illness of older people for which new treatment options are needed.”
“GA101 demonstrates our ongoing commitment to the research and development of new medicines for this disease.”
Obinutuzumab is Roche’s most advanced drug in development for the treatment of hematological malignancies.
It has been specifically designed as the first glycoengineered, type 2 anti-CD20 monoclonal antibody in development for B cell malignancies.
Afutuzumab is a monoclonal antibody being developed by Hoffmann-La Roche Inc. for the treatment of lymphoma.[1] It acts as an immunomodulator.[2][3] It was renamed obinutuzumab in 2009.[4]
