Clinical Details

Official title: Dideoxycytidine ( Ro 24-2027 ). A Treatment Protocol for the Use of Dideoxycytidine ( ddC ) in Patients With AIDS or Advanced ARC Who Cannot Be Maintained on Zidovudine ( AZT ) Therapy.

Study design: Endpoint Classification: Safety Study, Masking: Open Label, Primary Purpose: Treatment


Minimum age: 12 Years. Maximum age: N/A. Gender(s): Both.


Inclusion Criteria Concurrent Medication: Allowed:

- Aerosolized Pentamidine or Trimethoprim/sulfamethoxazole prophylaxis against

Pneumocystis carinii pneumonia is recommended.

- Dapsone is permitted but discouraged.

- Drugs that could cause other serious toxicity when coadministered with study

medication is allowed for treatment of an acute intercurrent illness or opportunistic infection at the investigator's discretion.

- Any medication that has the potential to cause peripheral neuropathy should be

avoided; patients should consult their physicians for specific drugs.

- Isoniazid is permitted if there is no evidence of peripheral neuropathy at entry and

the patient is taking pyridoxine = or > 50 mg/day.

- Metronidazole is permitted only with a study drug interruption.

- Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole,

ganciclovir, intravenous pentamidine, intravenous acyclovir = or > 1000 mg/day orally or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent (weekly) laboratory assessments, as appropriate.

- Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might

be expected to cause increased toxicity when co-administered with ddC.

- The following experimental medications are allowed if, in the judgement of the

investigator, no serious additive toxicities are anticipated and the experimental drug is necessary for optimal patient management:

- Ampligen, azithromycin, BW 566C80, bovine colostrum, clarithromycin, diclazuril,

foscarnet, oral ganciclovir, GM-CSF, G-CSF, hypericin, IL-2, interferon-beta, interferon-gamma, itraconazole, liposomal amphotericin, liposomal gentamicin, nimodipine, PEG-IL2 (polyethylene glycosylated IL-2), roxithromycin, spiramycin, trimetrexate. Patients must have the following:

was not the reason for discontinuation of other anti-HIV therapy.

- Any finding suggestive of peripheral neuropathy found at baseline neurological exam.

If a patient has an isolated finding of an absent achilles reflex he may be entered if no signs or symptoms and no other findings are suggestive of peripheral neuropathy.

- Concomitant treatment with excluded medications. Excluded medications include any

other experimental drugs (including ddI), drugs with known nephrotoxic or hepatotoxic potential, and drugs likely to cause peripheral neuropathy.
