The present invention provides novel salts of nilotinib and polymorphs thereof. The acid addition salts of nilotinib with benzenesulfonic acid, butanedisulfonic acid, 1-5- naphthalenedisulfonic acid, naphthalene-1-sulfonic acid and 1-hydroxynaphthoic acid; hydrates and anhydrates thereof.
Nilotinib, 4-methyl-N-[3-(4-methyl-lH-imidazol-l-yl)-5-(trifluoromethyl)phenyl]-3-[[4-(3-pyridinyl)-2-pyrimidinyl] amino] -benzamide, having the following formula

is marketed under the name Tasigna® in US and Europe. Tasigna contains nilotinib monohydrate monohydrochloride salt and is available as capsules for the treatment of adult patients with newly diagnosed Philadelphia chromosome positive chronic myeloid leukemia (Ph+ CML) in chronic phase. Tasigna is also indicated for the treatment of chronic phase and accelerated phase Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) in adult patients resistant or intolerant to prior therapy that included imatinib.
Nilotinib is considered a low solubility/low permeability (class IV) compound in the Biopharmaceutics Classification System (BCS). Therefore, dissolution of nilotinib can potentially be rate limiting step for in-vivo absorption. It is soluble in acidic media; being practically insoluble in buffer solutions of pH 4.5 and higher.

Sun Pharma to acquire GSK’s Australian opiates business

Sun Pharma to acquire GSK’s Australian opiates business
India-based Sun Pharmaceutical Industries has agreed to acquire GlaxoSmithKline’s (GSK) opiates business in Australia.
The agreement has been signed by wholly-owned subsidiaries of both firms, with the financial terms not disclosed.
Sun Pharma API business executive vice-president Iftach Seri said: “The global opiates market holds good potential and the addition of GSK’s Opiates business will strengthen our positioning further.”
Sun Pharmaceutical Industries Ltd(SUN.NS), India’s largest drugmaker by sales, said on Tuesday it has agreed to buy GlaxoSmithKline’s(GSK.L) opiates business in Australia to strengthen its pain management portfolio.
The business consists of analgesics made from raw materials found in opium poppy plants, and includes two manufacturing sites in the states of Tasmania and Victoria.
Financial details of the deal were not disclosed. A Sun Pharma spokesman declined to comment. Glaxo did not immediately respond to a request seeking comment.
Glaxo supplies a quarter of the world’s medicinal opiate needs from poppies grown by farmers in Tasmania, according to the company website. The company’s Australian opiates business brought in revenue of A$89 million ($69.63 million) in 2013.
Australia’s poppy industry is the world’s largest legal supplier of pharmaceutical grade opiates for painkillers, and Glaxo is one of three firms that control the crop and production in Tasmania.
The other two are Johnson & Johnson’s (JNJ.N) unit Tasmanian Alkaloids, and privately-held TPI Enterprises.
Glaxo’s decision to part with the opiates business comes as Tasmania’s poppy industry is facing a tough crop and the United Nations is expected to cut the state’s poppy crop area this week.
Glaxo said the deal would allow it to “focus on delivering its innovative product portfolio” in Australia.
“The opiates business has been an important part of our Australian business for many years, but as our portfolio transitions, we believe now is the right time to hand this business over to someone else,” Steve Morris, general manager of GSK Opiates, said in a statement.
The business employs 185 staff, including 155 in Victoria state and 30 in Tasmania state. Sun Pharma said it would hire all employees from both sites.
“The acquisition is a part of our strategy towards building our portfolio of opiates and accessing strong capabilities in this segment,” said Iftach Seri, executive vice president of the active pharmaceuticals ingredients business at Sun Pharma.
Both companies said they expect to close the deal by August.
Sun Pharma shares closed 1.93 percent higher on Tuesday, while the broader Nifty rose 0.44 percent.

Sun Pharma has bought Ranbaxy for $4 billion to create the world’s fifth-biggest generic drugmaker.
Dilip sanghvi, sun pharma promoter
The move will make the company the largest pharma firm in India, while Daiichi Sankyo – majority owner of Ranbaxy – will become the second largest shareholder in Sun Pharma with a 9% stake and the right to nominate one director to Sun Pharma’s Board of Directors. http://www.pharmatimes.com/Article/14-04-07/Sun_buys_Ranbaxy_for_4_billion.aspx

Dilip Shanghvi, Managing Director of Sun Pharma said in a release, “Ranbaxy has a significant presence in the Indian pharma market and in the US where it offers a broad portfolio of ANDAs and first-to-file opportunities. In high-growth emerging markets, it provides a strong platform which is highly complementary to Sun Pharma’s strengths,”
Under the agreement, Ranbaxy shareholders will get 0.8 shares of Sun Pharma for each Ranbaxy share.
Arun Sahwney, managing director and chief executive officer of Ranbaxy said in a statement, “Sun Pharma has a proven track record of creating significant long-term shareholder value and successfully integrating acquisitions into its growing portfolio of assets,”
Who Will Benefit?
Daiichi Sankyo Co. Ltd is the parent company of Ranbaxy as they acquired it from previous promoters and investors. As soon as Ranbaxy was acquired, their plants came under a scanner from US Food and Drug Administration (FDA), which troubled Daiichi as their own reputation was under stake.
Now, they will be the most relived entity as Sun Pharma will manage all such cases pertaining to Ranbaxy. Daiichi will now control 9% of Sun Pharma as a result of the current acquisition.
Insiders are claiming that Daiichi will sell this 9% stake as well and come out of the business all together.
Ranbaxy shareholders have cheered this latest development as their shares have gained since the announcement of this deal.
