3 Biggest Biotech Crashes This Month

By Keith Speights, The Motley Fool

Filed under:

What a month! The Dow set all-time highs. So did the S&P 500. But March wasn’t so great for everyone. While the big indexes enjoyed the thrill of victory, these three biotechs experienced the agony of defeat. Here’s what happened.

Serious impact
Impax Laboratories 
suffered from a comedy of errors. Unfortunately, the impact on its shares wasn’t so funny. Shares sank more than 22% during the month.

The culprit for the stock decline was none other than Impax itself. Back in March of last year, the Food and Drug Administration conducted an inspection of the company’s manufacturing facility in Hayward, Calif. Impax Labs had plenty of time to correct those problems. However, when the FDA completed its follow-up inspection earlier this month — one year later, three of the same problems were cited again. To make things worse, the FDA found nine new issues.

In response to the problems, CEO Larry Hsu stated that the company “committed significant resources in [its] efforts to meet FDA requirements.” Obviously, those resources and efforts weren’t enough.   

A long fuse
With a long fuse on a stick of dynamite, you know the explosion is still coming, even if it might take a little longer. The same type of situation has applied for Spectrum Pharmaceuticals . Many observers have expected for quite a while that Fusilev sales would eventually bomb. The explosion finally came in March, resulting in about a 35% drop in Spectrum’s shares.

Critics have been saying for months that sales for non-Hodgkin’s lymphoma drug Fusilev would fall as providers turned to generic alternatives. Fusilev enjoyed an extended period of high sales volumes resulting largely from shortages of generic leucovorin, driving Spectrum’s revenue up tremendously. However, that shortage ultimately ended as Teva and Sagent Pharmaceuticals cranked out more supply.

The anticipated firestorm hit in mid-March after Spectrum announced revenue guidance 40% lower than previously expected.This huge guidance cut stemmed from hospitals that switched to generics. No surprise there. Spectrum insisted that demand for Fusilev in clinics was “stable” and that “solid demand” was anticipated for 2013. Unfortunately for Spectrum, “stable” and “solid” aren’t words that can be accurately used to describe its stock these days.

The biggest crash of all
Impax and Spectrum might have had bad months, but at least they still look better than Ziopharm Oncology . Ziopharm’s stock collapsed more than 60% in March following bad news from a late-stage clinical trial this week.

The company had high hopes that palifosfamide would prove to be a potent treatment for metastatic soft tissue sarcoma. However, the drug failed to significantly improve progression-free survival, the primary endpoint of the phase 3 clinical study. Despite the study’s independent data monitoring committee’s recommendation for continued analysis to follow up on overall survival rates, Ziopharm decided to pull the plug on the program entirely.

What’s next for Ziopharm? The company says it will now regroup and focus on its synthetic biology programs.

3 Potential Game-Changing Cancer Drugs

By Keith Speights, The Motley Fool

Filed under:

Cancer just might be one of the scariest words in the English language. What goes through your mind when you hear that someone close to you has cancer? Sadness, probably. Fear, quite possibly. And there’s always a sense of relief if you learn that the cancer is treatable.

The good news is that more and more forms of cancer are treatable, with researchers marching full steam ahead to discover more effective treatments. Some of these treatments build upon previous approaches while others introduce surprising new twists. Here are three intriguing approaches to fighting cancer that could be on the way.

1. Feed a virus, starve a cancer
You have probably heard the old expression, “Feed a cold, starve a fever.” Now there could be a new spin on the old adage: Feed a virus, starve a cancer.

Oncolytics Biotech counts more than a dozen clinical trials under way with its product, Reolysin, targeting various forms of cancer. Reolysin is Oncolytics’ proprietary version of respiratory enteric orphan virus, or reovirus. Chances are pretty good that you have had a personal encounter with the all-too-common reovirus sometime in your life. 

When the reovirus infects a typical human cell, the cell fights back and keeps the reovirus from replicating. However, Oncolytics’ research found that this doesn’t happen when the reovirus infects a cancer cell. Instead, the reovirus replicates like crazy — and that ultimately kills the cancer cell.

A late-stage trial for Reolysin in treating head and neck cancers is under way. Oncolytics announced positive preliminary results in December from this study. The company has also seen positive results from mid-stage trials for Reolysin focusing on the treatment of lung cancer andcolorectal cancer. 

Meanwhile, Amgen thinks it might be on track to fight cancer using another virus. Talimogene laherparepvec is an experimental drug currently being studied for the treatment of melanoma. The drug uses the herpes simplex virus, or HSV, tag-teamed with a GM-CSF cytokine to harness the body’s immune system to kill cancer cells. Amgen expects to announce late-stage results this year.

2. From World War I to the war on cancer
The German army introduced the use of mustard gas during World War I. Several years later, though, scientists researched the possibility for the alkylating agents previously used for mustard gas to treat cancer. This work paid off with several chemotherapies ultimately stemming from the research over the next few decades.

One of the latest cancer drugs to emerge from research on alkylating agents is Ziopharm Oncology‘s  palifosfamide. Like other alkylating agents, palifosfamide works by interfering with the DNA of cancer cells. Alkylating agents have proven to be quite effective but also can be extremely toxic. A key advantage for palifosfamide is that the drug was designed to be much more tolerable than other similar chemotherapies.

Ziopharm has two late-stage clinical studies in progress for palifosfamide. The study farthest along targets treatment of metastatic soft tissue sarcoma using palifosfamide in combination with doxorubicin. Ziopharm expects to announce initial results from this study within the …read more
