I have seen no documents that support your opinion/speculation. Saying so does not make it so. Useless speculation on everyone's part/opinions re money flow.
MSK is well funded. PPHM is prepared to supply the Bavituximab. As Cp said, the agreement as PR'd supplies no details on money flow.
Per biopharm: "Maybe them sponsoring is simply PPHM supplying the Bavituximab or PS Targeting agent drugs."
