MM-398

MM-398 is a novel, stable nanotherapeutic encapsulation of irinotecan.  The U.S. Food and Drug Administration (FDA) has granted MM-398 orphan drug status for use in the treatment of pancreatic cancer.  PharmaEngine, Inc. has rights to develop and commercialize MM-398 in Taiwan under the designation PEP02.  


Title:  Identifying differential mechanisms of action for MM-398/PEP02, a novel nanotherapeutic encapsulation of irinotecan

Poster Session: Topoisomerase Inhibitors

Date/Time: Tuesday, Nov 15, 2011, 12:30 PM – 2:30 PM

Location: West Hall, Level One, Moscone Center West




MM-121

MM-121 is a monoclonal antibody designed to block signaling through the ErbB3 (HER3) receptor. MM-121, in partnership with Sanofi, is in clinical development in patients with breast, lung and ovarian cancer.


Title:  Targeting ErbB3 (HER3) and EGFR in Lung Cancer Patients: A Phase I Trial of MM-121 in Combination with Erlotinib in Patients with Non-Small Cell Lung Cancer (NSCLC)

Poster Session: Clinical Trials 3

Number: C27

Date/Time: Tuesday, Nov 15, 2011, 12:30 PM – 2:30 PM

Location: West Hall, Level One, Moscone Center West




MM-111

MM-111 is a novel bispecific antibody against ErbB3 (HER3), using an ErbB2 (HER2) targeting arm to enhance avidity and inhibition.  


Title:  Optimization of MM-111 and lapatinib dosing regimens using mathematical modeling and quantitative biology

Poster Session: Pharmacokinetics and Pharmacodynamics 3

Number: C118

Date/Time: Tuesday, Nov 15, 12:30 PM – 2:30 PM

Location: West Hall, Level One, Moscone Convention Center West




MM-302

MM-302 is a nanotherapeutic encapsulation of doxorubicin designed to target ErbB2 (HER2) overexpressing cancer cells, while limiting uptake into non-target cells.


Title:  HER2-targeted liposomal doxorubicin, MM-302, has a favorable cardiosafety profile in preclinical models

Poster Session: Novel Assay Technology

Number: C90

Date/Time: Tuesday, Nov 15, 2011, 12:30 PM – 2:30 PM

Location: West Hall, Level One, Moscone Center West




MM-151

MM-151 is a mixture of three fully human monoclonal antibodies directed against distinct non-overlapping epitopes in EGFR.


Title:  Elucidating mechanisms of action of MM-151, a mixture of three human antibody antagonists targeting EGFR

Poster Session: Therapeutic Agents: Biological 1

Number: A210

Date/Time: Sunday, Nov 13, 2011, 12:30 PM – 2:30 PM

Location: West Hall, Level One, Moscone Center West

Location: West Hall, Level One, Moscone Center West




MM-141

MM-141 is a comprehensive IGF-1R signaling inhibitor that is designed to address the redundancies that occur in tumors where both IGF-1R and ErbB3 (HER3) are activated, an approach intended to improve patient response by blocking survival signaling promoted by two separate pathways.


Title:  Therapeutically targeting redundant, growth factor-induced pro-survival signaling with MM-141, a novel bispecific antibody targeting IGF-1R and ErbB3 (HER3)

Poster Session: Therapeutic Agents: Biological 2

Number: B205
