Brief summary: The objective of this open-label study regimen is to make didanosine (ddI) available to patients with AIDS who are clinically deteriorating on zidovudine (AZT) and cannot enter the Phase II ddI programs due to protocol exclusion or geographic location.


Eligibility criteria: Inclusion Criteria

Concurrent Medication:

Allowed:

* Concurrent medications for treatment of complications of AIDS are allowed.
* Aerosolized pentamidine.
* Phenytoin, but with caution.
* Note:
* Extreme caution should be exercised in the use of didanosine (ddI) in any patient receiving concurrent therapies, particularly those receiving other nucleosides (e.g., ganciclovir), drugs with toxicities similar to those observed with ddI (list included under concomitant medications section of protocol), and other drugs with significant toxicities, including many drugs used for treatment of major opportunistic infections.

Patients must be:

- Not suitable for entry into ddI phase II studies by reason of inclusion or exclusion criteria or by reason of geographic location.

Able to provide signed informed consent (parent/guardian as appropriate). Available for monthly follow-up while taking ddI. Meet required baseline laboratory values within 14 days prior to initial drug dosing.

Note:

* Extreme caution should be exercised in the use of ddI in any patient receiving concomitant therapies, particularly those receiving other nucleosides (e.g., ganciclovir), drugs with toxicities similar to those observed with ddI (list included under concomitant medications section of protocol), and other drugs with significant toxicities, including many drugs used for treatment of major opportunistic infections.

Caution should also be exercised in a patient having intractable diarrhea or patients following a low-sodium diet. Physicians caring for these patients must perform clinical and laboratory evaluations every 7-10 days for the first 2 months of ddI therapy. Should any adverse effect of any severity be detected during this period of intensive clinical and laboratory monitoring, the physician must call Bristol-Myers Squibb (1-800-662-7999). If the patient continues ddI therapy, Bristol-Myers Squibb will require submission of follow-up and adverse experience report forms every 10 days. Although data are not available to fully assess the risks associated with the use of ddI in high-risk patients (for example, patients with preexisting disorders of body systems known to be adversely affected by ddI, particularly those with history of peripheral neuropathy, pancreatitis, seizure disorder, cardiac abnormalities, gout, and significant elevations of liver function test results), all such patients must have clinical and laboratory evaluations performed every 10 days and results submitted to Bristol-Myers Squibb on the case report forms provided.

* Taking phenytoin concomitantly.
* Grade B or greater peripheral neuropathy.

Concurrent Medication:

Excluded:

* Zidovudine (AZT).
