Public HealthPoniard Rally To Continue: Strong Efficacy And Safety Data From Picoplatin
Poniard announced positive Phase II data from its two trials in CRC and CRPC with picoplatin this morning, including efficacy that was comparable to the current standard of care, with a significantly improved safety profile. We believe that these data provide further evidence of picoplatin"s favorable efficacy and safety profile in two more large oncology markets, in addition to SCLC, and position picoplatin as a platform treatment that can provide solutions in multiple oncology settings. We believe that given these data from CRC and CRPC, in addition to the anticipated Phase III SPEAR data in SCLC, will attract the interest of multiple players and we expect that Poniard will be able to at least secure a large pharma partnership sometime this summer, unless a company like Sanofi (SNY Not Rated), Takeda (TKD Not rated), or Bristol-Myers Squibb (BMY Not Rated) decide to step in and acquire the whole company, for rights to both the IV and oral version of picoplatin.
The CRC Phase II trial data.
In this randomized Phase II trial, 101 chemo-naive metastatic CRC patients treated with picoplatin in the FOLPI regimen demonstrated median PFS of 6.8 months, versus 7.0 months in patients treated with the current standard of care, oxaliplatin-containing, FOLFOX-6 regimen, while exhibiting very similar disease control (75% vs. 76% respectively). The main differentiating factor between the two treatment regimens was the reduced occurrence of neuropathy (29% in FOLPI vs. 60% in FOLFOX6), including a statistically significant difference in Grade Âõ neuropathy (0% vs. in FOLPI vs. 16% in FOLFOX6, p-valueThe CRPC Phase II trial data.
In this Phase II trial, 32 chemo-naïve CRPC patients treated with picoplatin in combination with docetaxel and prednisone, showed a 78% rate of PSA response, versus the 45% observed in the TAX-327 arm of q3w docetaxel. In addition, median PFS was 8.5 months, and 58% of the patients achieved disease control. On the safety front, there was no neurotoxicity observed, in contrast to what was observed in TAX-327, with 30% neuropathy, including 2% severe neuropathy.
