Randomized Phase I Study of Trimetrexate Glucuronate (TMTX) With Leucovorin (LCV) Protection Plus Dapsone Versus Trimethoprim / Sulfamethoxazole (TMP/SMX) for Treatment of Moderately Severe Episodes of Pneumocystis Carinii Pneumonia
Randomized Phase I Study of Trimetrexate Glucuronate (TMTX) With Leucovorin (LCV) Protection Plus Dapsone Versus Trimethoprim / Sulfamethoxazole (TMP/SMX) for Treatment of Moderately Severe Episodes of Pneumocystis Carinii Pneumonia

To evaluate the safety of the combination of trimetrexate glucuronate (TMTX) and dapsone with leucovorin protection versus trimethoprim/sulfamethoxazole (TMP/SMX) in patients with AIDS and moderately severe Pneumocystis carinii pneumonia (PCP). To determine the pharmacokinetic parameters of TMTX, leucovorin, and dapsone and of TMP/SMX when given to patients with AIDS and moderately severe PCP.

Inclusion Criteria

Concurrent Medication:

Allowed:

  • Empiric therapy for other opportunistic pulmonary infection (TB or fungi) for the first 72 hours of study enrollment ONLY, until presence of suspected pathogens can be confidently excluded.

Patients must have:

  • AIDS.
  • Confirmed diagnosis of PCP.
  • Alveolar-arterial differences in dissolved oxygen >= 35 mm Hg but < 55 mm Hg on room air.

Exclusion Criteria

Co-existing Condition:

Patients with the following symptoms or conditions are excluded:

  • Severe renal or hepatic dysfunction.
  • Serious or life-threatening intolerance to TMP/SMX, TMTX, or dapsone.
  • Concurrent pneumothorax.
  • Active pulmonary tuberculosis or other inadequately treated opportunistic pulmonary infection (e.g., Cryptococcus neoforms, CMV). NOTE:
  • Identification of Mycobacterium avium or CMV in sputum or BAL fluid does not exclude, since these organisms may be present without causing disease.
  • Pulmonary Kaposi's sarcoma.
  • Active opportunistic infections or malignancies requiring induction therapy with bone marrow suppressive drugs (e.g., ganciclovir) or hepatotoxic drugs (e.g., chemotherapy).
  • Unable to have arterial blood gases on room air obtained at baseline.
  • Unwilling to undergo bronchoscopy, if sputum induction does not reveal Pneumocystis carinii.
  • Suspected malabsorption (e.g., ileus or severe diarrhea with > 6 stools/day).
  • Known absence of G6PD activity.
  • Large volume (1.0 to 1.5 liters) of intravenous fluid (5 percent in water) per 24 hours is medically inadvisable.
  • Unwilling to comply with study design.

Concurrent Medication:

Excluded:

  • Induction therapy with bone marrow suppressive drugs (e.g., ganciclovir) or hepatotoxic drugs (e.g., chemotherapy).
  • AZT, ddI, ddC, d4T, or other antiretroviral therapy.

Patients with the following prior condition are excluded:

Prior history of serious or life-threatening intolerance to TMP/SMX. (NOTE:

  • Patients with less severe reactions may be included at the discretion of the investigator and primary care provider.)

Prior Medication:

Excluded:

  • More than 24 hours of systemic anti-PCP therapy within 2 weeks prior to study entry.
