Geron Stock Rises after Positive Interim Update on Imetelstat

Read MoreHide Full Article

Shares of Geron Corporation (GERN - Free Report) increased almost 20% on Monday after it provided a positive update on two late-stage studies for imetelstat, its lead pipeline candidate.

So far this year, Geron’s shares have outperformed the Zacks classified Medical - Biomedical and Genetics industry. The stock rose 23.7% during the period while the industry witnessed a gain of 2.9%.

Telomerase inhibitor, imetelstat, is being developed for the treatment of hematologic myeloid malignancies like myelofibrosis (MF) and myelodysplastic syndromes (MDS).

Geron informed that partner Johnson & Johnson’s (JNJ - Free Report) subsidiary Janssen has completed the second internal data review of two studies, IMbark (phase II for the treatment of MF) and IMerge (phase II/III for the treatment of MDS), on imetelstat.

We remind investors that in September last year, Janssen had announced unfavorable findings from the planned internal reviews of initial data from IMbark and IMerge. As a result of the analysis, Janssen had then said that clinical activity of imetelstat, in the 4.7 mg/kg dosing arm, in the IMbark study did not warrant any further investigation and that it will no longer enrol new patients.

In March this year, Geron informed that the treatment of patients remaining on study in IMbark and IMerge is ongoing to obtain additional and more mature data. However, new patient enrollment in both trials was suspended until completion of the second internal data reviews by Janssen.

Following the second internal review, for IMerge, Janssen said that the benefit/risk profile of imetelstat in the treated patients supports continued development in lower risk MDS indication. The companies plan to provide a data package and proposed trial design refinements to the FDA. Geron mentioned that if Janssen decides to proceed to Part 2 of IMerge (a larger, 170 patient, Phase III portion), patient enrollment will begin in the fourth quarter of this year.

For IMbark, the recent results suggest that the clinical benefit and a potential overall survival benefit observed supports continuation of the trial without modifications. The trial that assesses the safety and efficacy of imetelstat treatment in relapsed or refractory MDS will also include an assessment of overall survival. Also, the data suggest that 9.4 mg/kg is an appropriate starting dose in the study.

We remind investors that in Nov 2014 Geron entered into a license and collaboration agreement with Janssen, granting the latter exclusive worldwide rights to develop and commercialize imetelstat for all human therapeutic uses, including hematologic myeloid malignancies.

Geron currently carries a Zacks Rank #2 (Buy). You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
