Pharmacyclics Inc. (NASDAQ: PCYC) is seeing shares surge today after it said that its Phase 1/2 trial of motexafin gadolinium plus antibody targeted radiation therapy demonstrated a high complete response rate in patients with non-Hodgkin’s lymphoma. The results of the study showed a 46% complete response rate in patients with multiply recurrent non-Hodgkin’s lymphoma who were treated with motexafin gadolinium in combination with Yttrium-90 Ibritumomab Tiuxetan, an approved antibody-targeted radiation therapy.
Patients were treated with a standard dose of Zevalin administered with 2.5 to 5.0 mg/kg of MGd given for six days. Of the 28 evaluable patients in the study, 46% showed a complete response and 11% more showed a partial response. Rituximab refractory patients showed an overall response rate of 86%, with a 64% complete response rate and a median time to progression of 14 months.
Adverse events seen were related to bone marrow suppression, an expected side effect of treatment with Zevalin.
This data was part of a presentation at the International Conference on Malignant Lymphoma. Shares are up some 19% at $1.25 today on more than 5-times volume. Its 520week trading range is $0.55 to $3.28 and its market cap is a mere $32.5 million even after the run. As of last quarter, it had roughly $21 million in liquidity from cash and equivalents.
