Hello Readers,

It has now been at least six months since we started joining the gloom and doom crowd, and, frankly, because of the Fed flooding the universe with funny money, we thought that soon a light would appear at the end of the black hole. Then, an eerie thing happened on the way to the hoped-for recovery. Energy and commodity prices have soared because of the Fed’s rush to bail out the wealthy; a few Newsletters ago, we called it welfare for Wall Street, or something along those lines. The best thing the Fed can now do is to do simply nothing and let the markets finally run their course. The more they interfere, the longer the pain continues. We would have preferred to have seen a cataclysmic sell-off because that would have signaled the end to the catharsis. We are navigating unchartered waters, but the bottom-fishing could be good.

Our picks for this Newsletter are two biotechs, both listed on NASDAQ.

KOSAN BIOSCIENCES, INC. (NASDAQ: KOSN) – $1.66 Twelve-month hi-low has been $6.53 – $1.28. Based in Hayward, CA, with about 80 employees, this biotech has 42.6 million shares outstanding, $71.8 million in total current assets, $77.86 million in total assets, little debt, and $18.31 million in total liabilities. Institutional ownership is around 87%. Three analysts give the stock a “strong buy”, one a “moderate buy”, and two have it as a “hold”. www.kosan.com

Kosan Biosciences, Inc. is another one of those small biotechs with a healthy-looking balance sheet and some promising technologies, and it recently did a major restructuring so as to concentrate its resources on developing them. One of our main reasons for adding it to the Current Portfolio, however, is the number of analysts behind the stock.

Founded in 1995, and public for nearly seven years, Kosan bills itself as a cancer therapeutics company focusing on advancing two new classes of anti-cancer agents through clinical development: heat shock protein 90 (Hsp90) inhibitors and epothilones. Hsp90 inhibitors have a mechanism for targeting multiple pathways involved in cancer cell growth and survival. Kosan’s first and second generation Hsp90 inhibitor product candidates have demonstrated antitumor activity in multiple indications in early clinical trials. Its injectable suspension formulation of tanespimycin (KOS-953), the company’s first generation Hsp90 inhibitor and most advanced product candidate, is in Phase III clinical trial in combination with Velcade (bortezomib) for multiple myeloma, as well as in a Phase II clinical trial with Herceptin (trastuzumab) for HER 2-positive metastatic breast cancer.

Kosan claims that its epothilone drug candidates have the potential to compete in the emerging epothilone market. Epothilones inhibit cell division with a mechanism of action similar to taxanes, one of the most widely used classes of chemotherapeutic agents. The company’s compounds have been specially engineered to overcome resistance to taxanes and to have an attractive clinical profile. In mid-April, a Phase II trial of its lead epothilone drug candidate, KOS-1584, was initiated in patients with non-small cell lung cancer.

The company’s product portfolio also includes KOS-1803, a preclinical stage product for cancer; KOS-2187, a potent motilin receptor agonist that is in Phase I clinical testing for treating GERD; and KOS-2464, a preclinical stage product for cancer.

Unlike many small biotechs, Kosan does garner some revenues. During FY2007, ending 12/31/07, revenues were $22.7 million with net losses of $28.66 million.

Given the number of analysts following Kosan and the company’s balance sheet, the stock could be worth a shot.

Our 24-month target for the stock is $2.50 to $3.00.

ZIOPHARM ONCOLOGY, INC. (NASDAQ: ZIOP) – $3.00. Twelve-month hi-low has been $6.50 – $2.08. Located in New York City, with about 40 employees, this biotech has 21.4 million shares outstanding, $35.52 million in total current assets, $36.72 million in total assets, little debt, and $6.4 million in total liabilities. Institutional ownership is around 21%. Two analysts rate the stock a “strong buy”. www.ziopharm.com

We recently stumbled upon Ziopharm Oncology, Inc. while visiting the Business Week site. Besides having a decent balance sheet, we thought that using arsenic as a way of killing cancer was a novel idea.

Founded in 2003, and public for less than two years, Ziopharm, simply put, is developing a portfolio of in-licensed cancer drugs, focusing primarily on cancer therapeutics which are already on the market or in development. As we said, the company is using arsenic to treat cancer, or what some call ‘arsenicals’. There are other companies trying this, but Ziopharm uses arsenic which is organic and, therefore, supposedly reduces the most toxic side effects.

Ziopharm currently has three products in clinical development: Darinaparsin (ZIO-101) is in a Phase II trial in patients with advanced myeloma, patients with primary liver cancer, and patients with diverse hematological malignancies, and a Phase I trial has also begun involving oral administration. Palifosfamide (ZIO-201) is in late Phase II clinical trials in patients with advanced sarcoma and various advanced cancers, and a Phase I/II sarcoma trial is now underway. Indibulin (ZIO-301) is currently in a late Phase I trial in Europe and the U.S., and a Phase I/II combination trial has been initiated; Indibulin is a novel synthetic anti-mitotic agent that binds to tubulin, destabilizes microtubule polymerization, arrests tumor cell growth at the G2/M phase and inhibits cell mobility and metastasis.

Like many small biotechs, Ziopharm makes no money and shows a lot of losses. For example, in the 4thQT of FY2007, ending 12/31/07, revenue was zero and losses were $7.7 million.

The medical community has tried a lot of things to combat many forms of cancer. Why not arsenic? If it works……….?

Our 24-month target for the stock is $5.00 to $5.50.
