Top 5 Biotech Stocks To Watch Right Now: Telik Inc (TELK.PH)

Telik, Inc. (Telik), incorporated in 1988, is a clinical-stage drug development company focused on discovering and developing small molecule drugs to treat cancer. The Company discovers its product candidates using the Company�� drug discovery technology, Target-Related Affinity Profiling (TRAP). TELINTRA, its principal drug product candidate in clinical development, is a small molecule glutathione analog inhibitor of the enzyme glutathione S-transferase P1-1 (GST P1-1). TELCYTA, its other product candidate, is a small molecule cancer drug product candidate designed to be activated in cancer cells.

Clinical Product Development

TELINTRA is the Company�� lead small molecule product candidate in clinical development for the treatment of blood disorders, including cancer. It has a mechanism of action and acts by inhibiting GST P1-1, an enzyme that is involved in the control of cellular growth and differentiation. Inhibition of GST P1-1 results in the activation of the signaling molecule Jun kinase, a regulator of the function of blood precursor cells. Preclinical tests show that TELINTRA is capable of causing the death or apoptosis of leukemic or malignant blood cells, while stimulating the growth and development of normal blood precursor cells. TELINTRA has been studied in Myelodysplastic Syndrome (MDS) using two formulations. A liposomal formulation was developed for intravenous administration of TELINTRA and was used in Phase I and Phase II studies in MDS patients. The results from the Phase II intravenous liposomal TELINTRA clinical trials demonstrated that TELINTRA treatment was associated with improvement in all three types of blood cell levels in patients with all types of MDS, including those in intermediate and high-risk groups. An oral dosage formulation (tablet) was subsequently developed and results from a Phase I study with TELINTRA tablets showed clinical activity and the formulation to be well tole rated. In June 2011, the Company initiated a Phase II clini! c! al trial to evaluate TELINTRA tablets. In October 2011, the Company initiated an additional Phase IIb clinical trial to evaluate TELINTRA tablets. '

The activity and safety profile of tablet formulation allowed the Company to complete a Phase II trial of TELINTRA tablets in MDS. The primary objective of the Phase II TELINTRA tablet study was to determine the efficacy of TELINTRA. A multivariate logistic regression analysis was conducted to identify MDS disease prognostic factors associated with erythroid improvement response rates, including prior MDS treatment, age, gender, the international prognostic scoring system (IPSS), risk, Eastern Cooperative Group performance status, years from MDS diagnosis, MDS World Health Organization subtypes, anemia only versus anemia plus other cytopenias, dose schedule and starting dose. Results from this study show that TELINTRA is the first GSTP1-1 enzyme inhibitor shown to cause clinically reductions in red blood cell transf usions, including transfusion independence in low to intermediate-1 risk MDS patients, as well as improvement in platelet count and white blood cell levels in certain patients. TELINTRA, administered orally twice daily, appeared to be convenient and flexible for chronic treatment administration.

TELCYTA is a small molecule drug product candidate that the Company is developed for the treatment of cancer. TELCYTA binds to GST. TELCYTA has been evaluated in multiple Phase II and Phase III clinical trials, including trials using TELCYTA as monotherapy and in combination regimens in ovarian, non-small cell lung, breast and colorectal cancer. Results from these clinical trials indicate that TELCYTA monotherapy was generally well-tolerated, with mostly mild to moderate side effects, particularly when compared to the side effects and toxicities of standard chemotherapeutic drugs. When TELCYTA was evaluated in combination with standard chemotherapeutic drugs, the tolera bility of the combinations was similar to that expected! of e! ac! h drug ! alone.

Clinical activity including objective tumor responses and/or disease stabilization was reported in the TELCYTA Phase II trials; however, TELCYTA did not meet its primary endpoints in the Phase III studies. Positive results from a Phase I-IIa multicenter, dose-ranging study of TELCYTA in combination with carboplatin and paclitaxel as first-line therapy for patients with non-small cell lung cancer, or NSCLC, were published in a peer reviewed publication. Clinical data demonstrated positive results of TELCYTA in combination with carboplatin and paclitaxel in the treatment of first-line lung cancer followed by TELCYTA maintenance therapy. As of December 31, 2011, the Company had an on-going investigator-led study at a single site of TELCYTA in patients with refractory or relapsed mantle cell lymphoma, diffuse B cell lymphoma, and multiple myeloma.

Preclinical Drug Product Development

The Company has a small molecule compound, TLK60 404, in preclinical development that inhibits both Aurora kinase and VEGFR kinase. Aurora kinase is a signaling enzyme whose function is required for cancer cell division, while VEGF plays a key role in tumor blood vessel formation, ensuring an adequate supply of nutrients to support tumor growth. These lead compounds prevented tumor growth in preclinical models of human colon cancer and human leukemia by inhibiting both Aurora kinase and VEGFR kinase. A development drug product candidate, TLK60404, has been selected.

The Company, using its TRAP technology has discovered TLK60357, a novel, potent small molecule inhibitor of cell division. TLK60357 inhibits the formation of microtubules that are necessary for cancer cell growth leading to persistent G2/M cancer cell cycle block and subsequent cell death. This compound demonstrates potent broad-spectrum anticancer activity against a number of human cancer cells. This compound also displays oral efficacy in multipl e, standard preclinical models of cancer. TLK6059! 6, a pote! nt! VGFR kin! ase inhibitor, blocks the formation of new blood vessels in tumors. Oral administration of TLK60596 to animal models of human colon cancer reduced tumor growth.
