HIV-1 Attachment Inhibitor Prodrug BMS-663068:
Interactions with Rifabutin, with or without Ritonavir, in Healthy
Subjects....http://www.natap.org/2015/IAS/IAS_64.htm
 
ViiV Healthcare to acquire Bristol-Myers Squibb HIV R&D assets
- HIV attachment & maturation
inhibitors....http://www.natap.org/2016/HIV/010816_01.htm

 
The late stage R&D assets include an attachment inhibitor (BMS-663068) investigated in Phase III as a breakthrough therapy candidate for heavily treatment-experienced patients. The other two assets are maturation inhibitors. The first one (BMS-955176) is in Phase IIb research for treatment-naïve and treatment-experienced patients, with the second (BMS-986173) being a back-up candidate. A transitional services agreement will be in place to manage the transfer of the assets following completion of the deal with Bristol-Myers Squibb.
 
The acquisition of Bristol-Myers Squibb's HIV discovery programmes includes a novel biologic treatment with a triple mechanism of action (BMS-986197), a maturation inhibitor, an allosteric integrase inhibitor and a capsid inhibitor. As part of the agreement, a number of Bristol-Myers Squibb drug discovery employees will be offered the opportunity to transfer to ViiV Healthcare. Bristol-Myers Squibb will continue to provide some support to the discovery programmes pursuant to a service agreement.
