Vigna Law Group: Trial Work Product Critical in Depo-Provera Cases

Greg Vigna, MD, JD

Vigna Law Group seeks Depo-Provera complaint files as key trial evidence in meningioma litigation.

LOS ANGELES, CA, UNITED STATES, August 21, 2026 /EINPresswire.com/ -- “Putting together a trial work product requires this important discovery. My firm does this work, and we have asked for them through the California JCCP because, to our knowledge, these documents to date have not been provided for the Multidistrict Litigation,” states Greg Vigna, MD, JD, and national neurological injury attorney.

Dr. Greg Vigna, MD, JD, continues, "Nothing is more important than how a pharmaceutical company handles the first reported serious risk. In the Cook IVC litigation, it was a far-reaching perforation of the filter into adjacent arteries by Dr. Sadaf. I reviewed every adverse event in that litigation for the purpose of understanding internal communications that describe knowledge and conduct.”

Read Sadaf, “Significant Caval Penetration by the Celect Inferior Vena Cava Filter: Attributable to Filter Design?”, published in 2007 in the Journal of Vascular and Interventional Radiology: https://www.jvir.org/article/S1051-0443(07)01022-6/abstract

Dr. Vigna explains, “Internal documents of adverse events are essential in trials. By going to trial, internal confidential documents become public. As in the Cook IVC litigation, when physician experts learn about the documented challenges of a pharmaceutical company medical articles are written to analyze such situations.”

Read “Lessons From Celect: Building Transparency and Trust in Medical Devices”, published in JACC Journals, Archives. Vol. 85, No. 10: https://www.jacc.org/doi/full/10.1016/j.jacc.2025.01.002

Dr. Vigna concludes, “My firm, with other firms in the JCCP, is doing the work to understand knowledge of Upjohn, Pharmacia, and Pfizer, and that is by way of the internal documents from the complaint files that might include meningioma. Other discovery is being provided, because we have Bellwethers that need to be heard.”
