Best Gas Stocks To Invest In Right Now: Portola Pharmaceuticals Inc (PTLA)

Portola Pharmaceuticals, Inc. (Portola), incorporated on September 2, 2003, is a biopharmaceutical company developing product candidates that have the potential to represent advances in the fields of thrombosis and hematology. The Company is advancing its three wholly owned programs using biomarker and genetic approaches.

Betrixaban

Portola's compound, betrixaban, is an oral, once-daily Factor Xa inhibitor being evaluated in the only biomarker-based Phase-III study for hospital to home prophylaxis of venous thromboembolism (VTE) in acute medically ill patients. Betrixaban's properties particularly suited to potentially demonstrate efficacy without increasing bleeding in this patient population.

Andexanet Alfa

Portola's second development candidate, andexanet alfa (PRT4445), has the potential to be a reversal agent to directly reverse the effects of Factor Xa inhibitors in patients who suffer a bleeding episode or who require emergency surgery. Portola has entered into clinical collaboration agreements with all of the manufacturers of direct Factor Xa inhibitors, including Bristol-Myers Squibb and Pfizer (Eliquis [apixaban]), Bayer HealthCare and Janssen Pharmaceuticals (XARELTO [rivaroxaban]), and Daiichi Sankyo (Savaysa [edoxaban]), while retaining all decision-making and commercial rights to the program.

Cerdulatinib (PRT2070) and PRT2607

Portola's third wholly owned product candidate, cerdulatinib (PRT2070), is an orally available kinase inhibitor that uniquely inhibits two validated tumor proliferation pathways - spleen tyrosine kinase (Syk) and janus kinase (JAK). It is being studied in patients with leukemias or lymphomas with a focus on genetically-defined subtypes, as well as in patients who have failed therapy due to relapse or acquired mutations. Portola's fourth program is partnered with Biogen Idec and is focused on the development of PRT2607, a selective Syk inhibitor.

Advisors' Opinion:

• [By Todd Campbell]

  That leads me to Medivation (NASDAQ: MDVN  ) , Ophthotech (NASDAQ: OPHT  ) , and Portola (NASDAQ: PTLA  ) , three companies with important therapies that may very well be destined to become top sellers.

Advisors' Opinion:

• [By James E. Brumley]

  Since 2008's implosion from the stock, the interest in Savient Pharmaceuticals Inc. (NASDAQ:SVNT) has been waning. There was a brief burst of bullishness in September of last year, which stirred the bullish pot a little. But, when SVNT started to fade in October of that year - just as quickly as it had perked up - what lingering hopes there were for the stock finally started to melt away. By the middle of this year, pretty much everyone had written Savient Pharmaceuticals off as a lost cause. Big mistake. Over the last few days, SVNT has almost wiggled its way buck into a bullish zone.

• [By James E. Brumley]

  It's still too soon to say Savient Pharmaceuticals Inc. (NASDAQ:SVNT) is off and running. In fact, the stock's decidedly NOT off and running yet. But, it's not too soon to put SVNT on your watchlist of potential breakout candidates, as it's much closer to a breakout than most anyone can see.

Best Biotech Stocks To Invest In Right Now: TESARO Inc (TSRO)

TESARO, Inc. (TESARO), incorporated in March 2010, is a development-stage, oncology-focused biopharmaceutical company for cancer patients. The Company focuses on rolapitant and TSR-011 product. The Company�� marketed products and product candidates in development treat cancer through non-specific damage to cellular components or alter cell metabolism or internal repair mechanisms to the demise of cancer cells.

Rolapitant

Rolapitant is a potent and long-acting neurokinin-1, or NK-1, receptor antagonist is in Phase III clinical trials for the prevention of chemotherapy induced nausea and vomiting (CINV). It is in Phase III clinical trials. CINV, if not prevented by prophylaxis, has the potential to afflict up to 90% or more of cancer patients undergoing chemotherapy, depending upon the type of chemotherapy administered the dosing schedule of the chemotherapy, and the patients' age and gender, among other predisposing factors. Prolonged nausea and vomiting may result in unwanted weight loss, dehydration and malnutrition, as well as hospitalization. The Company has in-licensed the rights to rolapitant from OPKO Health, Inc.

TSR-011

TSR-011 is an orally available ALK inhibitor in preclinical development. ALK is known to be involved in certain types of cancers, including subsets of NSCLC, neuroblastoma and lymphoma. For patients in these subsets, the ALK gene is fused to an activating partner or contains point mutations, resulting in constitutive activation of ALK and the growth of cancer cells and tumor development. Inhibition of ALK in these cancer cells results in cell death and tumor growth inhibition or regression. In August 2011, the United States Food and Drug Administration approved the first ALK inhibitor, developed by Pfizer Inc., Xalkori (crizotinib), which was approved for the treatment of patients with locally advanced or metastatic NSCLC that are ALK positive.

The Company competes with GlaxoSmithKline plc, Roche Holding Ltd! . and Sanofi S.A.

Advisors' Opinion:

• [By Alexander Maxwell]

  One of the companies attempting to develop a better treatment for chronic diabetic foot ulcers is Osiris Therapeutics� (NASDAQ: OSIR  ) . Earlier this month, Osiris shares more than doubled as the company announced positive data for its CDFU drug Grafix. The study results were very impressive to say the least; the study was stopped early due to the overwhelming efficacy exhibited by the treatment. A main highlight is the fact that 62% of Grafix patients had their wound closed at 12 weeks, compared to only 21% of patients using conventional methods. Clearly, the efficacy in this endpoint was overwhelming. Grafix also achieved all of the secondary endpoints for the trial, and more importantly demonstrated a relatively benign safety record.�

  Additionally, stem cell therapies have remained elusive as the industry's ultimate Holy Grail. Osiris (NASDAQ: OSIR  ) received Canadian approval for the world's first stem cell drug, Prochymal, for children battling acute graft-versus-host disease, or GvHD, last year. The approval meant more symbolically than to the bottom line, but it definitely put the potential of stem cells front and center for investors.

• [By Lauren Pollock]

  Osiris Therapeutics Inc.(OSIR) said Friday a proposed ruling from the Centers for Medicare and Medicaid Services won’t immediately affect reimbursements for its Grafix stem-cell product. The regenerative medicine company said Grafix will maintain its current reimbursement status — also called transitional pass-through status — potentially through late 2015.

  A blast to the past
  It's occasionally very difficult to value biotech stocks, because of the wide range of outcomes possible given their pipelines. Other times, as in the case with Regulus Pharmaceuticals (NASDAQ: RGLS  ) , I bang my head against a table and wonder what the heck investors are thinking.

• [By Brian Orelli]

  Partners like this investment idea
  When Regulus Therapeutics (NASDAQ: RGLS  ) went public last year, investors weren't the only ones buying the share offering; Regulus' partners and founders clearly thought it was a good investment idea, because they bought more shares. Lots of them. AstraZeneca, Biogen Idec, Sanofi, GlaxoSmithKline�and Isis combined to purchase more than 70% of the shares that raised nearly $81 million for the biotech.

  Regulus Therapeutics (NASDAQ: RGLS  )
  Since presenting at the Deutsche Bank Healthcare Conference two weeks ago, shares of Regulus Therapeutics have been absolutely on fire. A mixture of ASCO and IPO fever have revived the love for newer issues, and having big name pharmaceutical companies gobbling up a majority of its IPO'd shares certainly helps its cause.
