The invention relates to a combination of treatments, more particularly a combination treatment for HIV-1 infection. The present invention is directed to the use of bryostatin-1 and their natural and synthetic derivatives for AIDS therapy, in particular to the use of bryostatins in combination with other active drugs such as Histone Deacetylases (HDACs) inhibitors and anti-retrovirals, for the treatment of HIV-1 latency. According to the present invention, we provide a combination therapy for the treatment of HIV-1 latency which employs bryostatin-1 (and analogues) and one of the following HDAC inhibitors; valproic acid, butyrate derivatives, hydroxamic acids and benzamides. While HDACi can be used in continuous dosing protocol, bryostatins can be used following a cyclical dosing protocol. Bryostatins can be formulated in pharmaceutical acceptable carriers including nanoparticles, phospholipids nanosomes and / or biodegradable polymer nanospheres. This combination therapy needs to be used in patients treated with antiretroviral therapy (HIV-1 protease inhibitors, HIV-1 reverse transcriptase inhibitors, HIV-1 integrase inhibitors, CCR5 co-receptor inhibitors and fusion inhibitors).

Boosted cytidine analogue reverse transcriptase inhibitor antiretroviral compound is a new therapeutic anti HIV option, in combination with another drug such as a NRTI or a protease inhibitor. It's heightened and sustained antiretroviral potency is due to the increased intracellular level of 3TC triphosphate, the active form of 3TC. This effect is obtained by combining 3TC, in usual doses, with a reduced dose of ddC, in the same pharmaceutical formulation. The product could be administered twice or even once daily, which is convenient, and does not increase the pill burden for the patient. The reduced ddC dosage prevents the occurrence of ddC related side effects. Other cytidine derivatives (racemic or negative enantiomers) could have the same effects as ddC and could probably be combined with 3TC, and have the same effect. On the other hand, low dose ddC may also increase the intracellular levels of other cytidine derivatives as it does for 3TC. Boosted cytidine analogue reverse transcriptase inhibitor antiretroviral compound could also be formulated in combination with another drug such as another NRTI (e.g. abacavir) or any protease inhibitor in the same capsule or tablet. This approach offers a dual anti-HIV therapy that is as efficacious as the routine triple therapy. In this way the HIV treatment cost could be significantly reduced which is imperative for resource-poor settings. This new formulation is convenient and well tolerated with no additional toxicity than that of the combining drug (NRTI or protease inhibitor) and 3TC. Moreover, this will enable a larger number of patients to benefit from the already known 3TC effects. It will also increase the 3TC effects in those organs or HIV sanctuaries with usually reduced 3TC concentrations or activity. It could be indicated in both the initial as well as in salvage HIV therapy. It could also be used for therapy optimization or simplification. Moreover, in combination with another NRTI such as abacavir, or even alone, it could be beneficial for reducing the HIV harm in resource-poor settings.
